Description

Electronic equipment and shutdown method thereof

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a shutdown method for an electronic device and an electronic device.

Background

Before shipping, an electronic device (e.g., a mobile phone, a tablet computer, etc.) needs to be tested many times, for example, an external device for testing the electronic device tests hardware performance (e.g., antenna performance, battery performance, etc.) of the electronic device. In the testing process, the electronic device is connected with an external device (for example, a personal computer or the like) through a Universal Serial Bus (USB) interface, after a tester finishes testing a certain performance of the electronic device through the external device, the tester may need to shut down the electronic device and disconnect the USB connection with the external device, put the electronic device in storage, and after a period of time, test other performances of the electronic device. For example, after the antenna performance of the electronic device is tested by the external device, the tester issues a shutdown instruction to the electronic device, and after the tester determines that the electronic device is shutdown, the tester disconnects the USB connection between the electronic device and the external device and puts the electronic device in storage.

However, when the tester issues the shutdown instruction to the electronic device through the external device, there may be a case where the instruction is delayed to issue, for example, the delay of issuing the shutdown instruction by the external device is 1 second, which results in a slow speed of disconnecting the USB connection between the electronic device and the external device by a production line worker. The electronic equipment is triggered to be started up when the electronic equipment is connected with the external equipment through the USB in a default mode during testing, and the electronic equipment is always connected with the external equipment through the USB in the testing process, so that the electronic equipment is triggered to be started up again when the speed of disconnecting the USB connection between the electronic equipment and the external equipment by testing personnel is low. After the electronic equipment is triggered to be started up again, if the display screen is not installed on the electronic equipment or the display screen is installed but the display function of the display screen is not started, the testing personnel default that the electronic equipment is shut down and put in storage. Under the condition, the electronic equipment is not shut down when being put in storage, so that the electric quantity of the battery of the electronic equipment is exhausted after the electronic equipment is put in storage, the battery needs to be disassembled and replaced when the electronic equipment is tested next time, and a large amount of manpower and financial resources are consumed.

Or the external device is connected with the electronic device through a wireless network during testing, and the electronic device controls the electronic device to be powered off and put in storage after determining that the wireless network connection between the external device and the electronic device is disconnected, so that the electronic device is successfully powered off and put in storage after the external device finishes testing the electronic device, the labor is saved, and the efficiency of powering off the mobile phone is improved.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, an embodiment of the present application provides a shutdown method for an electronic device, where the electronic device is connected to an external device for testing the electronic device through a USB, and the shutdown method includes: the electronic equipment receives a shutdown instruction, wherein the shutdown instruction is used for indicating the electronic equipment to shut down; responding to a shutdown instruction, the electronic equipment acquires a state value of the USB, wherein the state value is used for reflecting the connection state of the USB; under the condition that the electronic equipment determines that the state values of the USB acquired within the first preset time are all the first preset values, the electronic equipment determines that the USB connection between the electronic equipment and the external equipment is disconnected; the electronic equipment controls the electronic equipment to be powered off.

Therefore, the electronic equipment controls the electronic equipment to be shut down and put in storage after the electronic equipment determines that the USB connecting line between the external equipment and the electronic equipment is disconnected according to the state value of the USB acquired within the first preset time, the problem that the electronic equipment is immediately restarted when the external equipment is connected with the electronic equipment through the USB and the electronic equipment is shut down but the USB is not disconnected is solved, and the problem that the battery power of the electronic equipment is exhausted due to the fact that the electronic equipment is not shut down and put in storage is solved.

In addition, after the electronic equipment acquires the state value of the USB within the first preset time, whether the USB connecting line between the external equipment and the electronic equipment is disconnected or not is judged according to the state value of the USB acquired within the first preset time, the problem of misjudgment on the connection state between the external equipment and the electronic equipment is solved, and the accuracy of determining the connection state between the external equipment and the electronic equipment is improved.

In one possible implementation manner, the receiving, by the electronic device, a shutdown instruction includes: the electronic equipment receives a shutdown instruction through a main thread; the electronic equipment acquires the state value of the USB, and comprises the following steps: the electronic equipment acquires the state value of the USB through the first sub thread, and the first sub thread and the main thread are executed in parallel.

The electronic equipment acquires the shutdown instruction and the USB state value through two parallel threads, and the processes of acquiring data through the two threads are mutually independent and interfere complementarily, so that the data acquisition efficiency is improved, and the code robustness is also improved.

In another possible implementation manner, acquiring the state value of the USB includes: calling a file opening function, and opening a storage file, wherein the storage file stores state values of the USB at different times; calling a reading function for multiple times periodically, and reading a USB state value from a storage file; calling a reading function to read one state value of the USB from the storage file each time; the shutdown method further comprises the following steps: and calling a closing function to close the storage file.

In some embodiments, the electronic device may call a file open function through the first child thread to open the storage file, and then the electronic device reads the state value of the USB from the storage file by periodically calling the read function multiple times through the first child thread. For example, the electronic device calls the read function multiple times through the first sub thread to read the state value of the USB within the first preset time length from the storage file. Then, the electronic equipment calls a closing function to close the storage file through the first sub-thread.

Therefore, the electronic device only calls the file opening function once through the first sub-thread, and then after the first sub-thread calls the reading function for multiple times to read the state values of the USB at multiple moments from the storage file, the first sub-thread calls the closing function to close the storage file. Therefore, the process that the storage file is opened only once and the state value of the USB is read for multiple times is achieved, and the problem that in the related technology, the storage file is opened once when the state value of the USB is read once, and then the storage file is closed once, so that the memory of the mobile phone is greatly consumed is solved.

In another possible implementation manner, the periodically calling the read function multiple times to obtain the state value of the USB from the storage file includes: calling a read-write position control function, and fixing a read pointer corresponding to the read function as a first position pointer; calling a reading function for multiple times based on the first position pointer, and reading one state value of the USB from the storage position indicated by the first position pointer in the storage file each time; and the storage position indicated by the first position pointer stores the state values of the USB at different times.

In some embodiments, the electronic device may call the read-write location control function through the first sub-thread, fix a read pointer corresponding to the read function as the first location pointer, and then call the read function multiple times based on the first location pointer, each time reading one status value of the USB from the storage location indicated by the first location pointer in the storage file.

It can be understood that the storage location indicated by the first location pointer stores therein the status values of the USB at different times, and the electronic device calls the read function to read the status values of the USB, so that the read function is ensured to read the status values of the USB from the storage location indicated by the first location pointer each time.

In another possible implementation manner, after the electronic device determines that the USB connection between the electronic device and the external device has been disconnected, the method further includes: the electronic equipment sends out prompt information; the prompt information is used for prompting that the USB connection between the electronic equipment and the external equipment of the user is disconnected; and controlling the electronic equipment to be powered off in response to the power-off operation of the user.

In some embodiments, after the electronic device determines that the USB connection line between the electronic device and the external device is disconnected, the electronic device may prompt the user by means of a voice prompt, and then the user may manually control the electronic device to power off. For example, the electronic device is powered off in response to a user operating a power-off key of the electronic device.

In another possible implementation manner, the shutdown method may further include:

and under the condition that the state value of the USB acquired by the electronic equipment is the second preset value, the electronic equipment continues to acquire the state value of the USB.

It can be understood that when the state value of the USB acquired by the electronic device is not the first preset value, the electronic device determines that the USB connection line between the electronic device and the external device is in a connection state, and the electronic device may continue to acquire the state value of the USB until the state values of the USB acquired by the electronic device within the first preset time period are all the first preset values, and the electronic device determines that the USB connection line between the electronic device and the external device is in a disconnection state.

It can be understood that, after the electronic device receives the shutdown instruction, if the external device sends a data acquisition instruction to the electronic device, and the electronic device does not receive the data acquisition instruction sent by the external device within the second preset time period, the electronic device may determine that the USB connection state between the electronic device and the external device is the disconnection state. Under the condition, the electronic equipment is controlled to be shut down and put in storage, and the electric quantity of the electronic equipment cannot be exhausted after the electronic equipment is put in storage.

In one possible implementation manner, the shutdown method may further include:

It is understood that, in order to implement the shutdown function of the electronic device, the electronic device includes hardware and/or software modules corresponding to the hardware and/or software modules for performing the respective functions. The present application can be realized in hardware or a combination of hardware and computer software in connection with the exemplary algorithm steps described in connection with the embodiments disclosed herein. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, with the embodiment described in connection with the particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

In this embodiment, the electronic device may be divided into functional modules according to the above method example, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module may be implemented in the form of hardware. It should be noted that the division of the modules in this embodiment is schematic, and is only a logic function division, and there may be another division manner in actual implementation.

For example, in a division manner, referring to fig. 3, fig. 3 is a schematic diagram of a software structure of an electronic device provided in an embodiment of the present application, and as shown in fig. 3, the electronic device may include a system library and a kernel layer.

Wherein, the system library can comprise a plurality of functional modules.

In the embodiment of the present application, the system library may include a first sub-thread, a data processing module, a data monitoring module, a second sub-thread, an audio prompting module, and a shutdown module.

The electronic device can acquire the state value of the USB through the first sub thread.

The data processing module is used for judging whether a USB connecting line between the electronic equipment and the external equipment is disconnected or not according to the state value of the USB.

The data monitoring module is used for monitoring WiFi signals in the mobile phone so as to judge whether WiFi connection between the external equipment and the electronic equipment is disconnected or not according to whether the WiFi signals are monitored or not.

The electronic device may obtain a data obtaining instruction sent by the external device through the second sub-thread, where the data obtaining instruction may be an instruction for obtaining single board information of the electronic device, an instruction for obtaining a calibration parameter of a radio frequency antenna of the electronic device, a related instruction for testing a current of the electronic device, and the like, and the data obtaining instruction is not limited herein.

The audio prompting module is used for prompting a user in a voice prompting mode after the USB connecting line or the wireless network between the electronic equipment and the external equipment is determined to be disconnected.

The shutdown module is used for controlling the electronic equipment to shut down according to the shutdown instruction.

The kernel layer is a layer between hardware and software. The kernel layer at least comprises a USB driver, a data acquisition module and a data monitoring module.

The USB driver is configured to drive a USB interface of the electronic device to receive an instruction sent by the external device, for example, when the external device is connected to the electronic device through the USB interface, the external device sends a shutdown instruction to the USB interface of the electronic device, and the USB interface of the USB driver drives the USB interface of the electronic device to obtain the shutdown instruction.

The data acquisition module is used for acquiring the USB state value from the storage file. The storage file comprises a plurality of storage positions, and one storage position stores state values of the USB at different moments.

The data monitoring module is configured to monitor whether the USB interface receives an instruction sent by the external device, for example, the data monitoring module may be configured to monitor whether the USB driver receives a shutdown instruction sent by the external device.

The technical solutions involved in the following embodiments can be implemented in an electronic device having the above hardware structure and software architecture. The following takes an electronic device as an example, and the present solution is exemplarily described.

In some embodiments, as shown in fig. 4, in a scenario where the mobile phone is connected to the external device through the USB connection line, after a performance test of the mobile phone by the external device is completed, the external device sends a shutdown instruction to the USB interface of the mobile phone through the USB connection line. For example, after the performance test of the external device on the radio frequency antenna of the mobile phone is completed, the external device sends a shutdown instruction to the USB interface of the mobile phone through the USB connection line. After the USB interface of the mobile phone receives a shutdown instruction sent by the external equipment, the data acquisition module of the mobile phone acquires the shutdown instruction from the USB interface through a serial port data thread, and the data processing module controls the mobile phone to shut down after determining that the USB connecting line between the mobile phone and the external equipment is disconnected according to the acquired USB state.

The USB state is used for representing the USB connection state between the mobile phone and the external equipment. The state value of the USB is used to reflect the USB state. For example, the state value of the USB is 1, which indicates that the mobile phone is connected to the external device through the USB connection line; the state value of the USB is 0, which represents that the USB connecting line between the mobile phone and the external equipment is disconnected.

Next, referring to fig. 5, the electronic device is taken as an example to explain the above process in detail, and fig. 5 is a first flowchart of a shutdown method provided in this embodiment of the present application. As shown in fig. 5, the method may include the steps of:

step 501, the external device sends a shutdown instruction to the USB interface of the mobile phone. Correspondingly, the USB interface of the mobile phone receives a shutdown instruction.

The power-off instruction is used for controlling the mobile phone to be powered off.

Because the mobile phone is connected with the external equipment through the USB connecting wire, data are transmitted between the mobile phone and the external equipment through the USB. In the embodiment of the application, after the external device finishes testing the mobile phone, the external device can send a shutdown instruction to the USB interface of the mobile phone through the USB connection line, and after the mobile phone is shutdown, the tester puts the mobile phone in storage for storage.

Step 502, the data monitoring module monitors that the USB interface receives a shutdown instruction.

Step 503, the data monitoring module stores the state value of the USB into a storage file.

In this embodiment of the application, the data monitoring module periodically monitors the open state of the USB interface (for example, every 100 ms) through the serial port data thread, and when the USB interface of the mobile phone is in the open state, after the data monitoring module monitors that the USB interface receives a shutdown instruction sent by the external device, the data monitoring module reads the shutdown instruction from the USB interface through the serial port data thread. That is, the data acquired by the serial port data thread includes a shutdown instruction, for example, the data acquired by the serial port data thread actmdserver may include the shutdown instruction.

Here, the serial port data thread may be a main thread, and is configured to obtain data from the USB interface and store the data in a storage file. For example, after the data monitoring module monitors that the USB interface receives a shutdown instruction sent by the external device, the data monitoring module periodically reads the state value of the USB from the USB interface through the serial data thread, and stores the state value read to the USB each time in the storage file.

For example, after the data monitoring module monitors that the USB interface receives a shutdown instruction sent by the external device, the data monitoring module monitors the connection state between the external device and the mobile phone every 1 second, and stores the state value of the USB into the storage file.

In step 504, the data monitoring module sends a serial port data thread to the data acquisition module. Correspondingly, the data acquisition module receives the serial port data thread.

In the embodiment of the application, after the data monitoring module reads the shutdown instruction through the serial port data thread, the data monitoring module sends the serial port data thread to the data acquisition module.

It is understood that the serial data thread may include various types of instructions, for example, the serial data thread may include an AP side instruction, an MA instruction or a Modem instruction. Here, after the data obtaining module receives the serial port data thread, the data obtaining module may determine, according to the instruction identifier of the shutdown instruction, that the shutdown instruction in the serial port data thread is the AP-side instruction. The instruction identifier may be used to identify the type to which the instruction belongs.

That is, each type of instruction has a corresponding instruction identifier, for example, the AP-side instruction, the MA instruction, and the Modem instruction have corresponding instruction identifiers, so as to identify the types corresponding to different instructions.

In this embodiment of the application, after the data obtaining module determines that the shutdown instruction in the serial port data thread is the AP side instruction, the AP side instruction may be analyzed by using an AP side instruction analysis logic, so as to obtain the first sub-thread. Wherein the first sub-thread may be a thread that is executed in parallel with the main thread.

It will be appreciated that different types of instructions have corresponding resolution logic, and that AP-side instructions herein also have corresponding AP-side instruction resolution logic.

It should be explained that each thread has a unique identifier to distinguish primary and secondary relationships among the threads. In addition, after a sub-thread is established in the main thread, the main thread and the sub-thread do not influence each other in their respective life cycles, that is, after the life cycle of the main thread is over, the sub-thread can continue to operate, or after the life cycle of the sub-thread is over, the main thread can continue to operate.

In step 505, the data obtaining module obtains the state value of the USB from the storage file.

The storage file comprises a plurality of storage positions, wherein one storage position stores the state values of the USB at different moments.

In the embodiment of the application, the data acquisition module can acquire the state value of the USB from the storage file through the first sub thread. For example, the data obtaining module obtains the state value of the USB through a first sub-thread thdddiagnotusb in the serial data thread atcmderver.

Because the first sub-thread and the main thread are two threads which are executed in parallel, when the data monitoring module reads the shutdown instruction through the main thread, the first sub-thread executes in parallel to acquire the state value of the USB, so that the robustness of codes is improved, and the execution efficiency is also improved.

Taking the example that the data obtaining module obtains the state value of the USB from the storage file through the first sub-thread thdddiagnotusb, in the related art, when the first sub-thread thdddiagnotusb obtains the state value of the USB from the storage file, the first sub-thread thdddiagnotusb obtains the state value of the USB by calling a file opening function, reading a function, and closing the function. Here, the file open function is used to open the storage file, the read function is used to read data stored in the storage file, and the close function is used to close the storage file. For example, the first sub-thread thdddiagnotusb acquires a state value of one USB stored in the storage file at a certain time by sequentially calling an open function, a read function, and a close function, where the first sub-thread thdddiagnotusb needs to continuously and cyclically execute a code "open-read-close" to acquire the state values of the USB stored in the storage file at different times. However, the first sub-thread continuously opens the storage file and then closes the storage file, which not only causes the memory of the mobile phone to be exhausted, but also destroys the robustness of the code.

In the embodiment of the application, when the data obtaining module obtains the state value of the USB by calling the file opening function, reading the function and closing the function through the first sub-thread, the first sub-thread may call the file opening function periodically and then call the reading function to read the state values of the USB stored in the storage file at different times, and then call the closing function to close the storage file. For example, after the first child thread calls the open function to open the storage file, the first child thread may periodically call the read function to read the state value of the USB within the first preset time duration stored in the storage file, and then call the close function to close the storage file. That is, the first child thread may acquire the state value of the USB within the first preset time duration stored in the storage file by executing the code "open while (1) { read } close".

Therefore, the process of the first sub-thread acquiring the state values of the USB stored in the storage file at different moments only calls the file opening function and the file closing function once. After the first sub-thread calls the file opening function to open the storage file, the reading function is called to read the state values of the stored USB at different moments in the storage file, and then the closing function is called to close the storage file. Therefore, the first sub-thread only opens the storage file once, and the problem that in the related art, the memory of the mobile phone is greatly consumed because the storage file is opened once when the state value of the USB is read once is solved, so that the processes of opening the file once and reading the state value of the USB for multiple times are realized.

In addition, since the read function (e.g., read function) is a common interface function, the mechanism is that after each time data stored in a current storage location in a storage file is read, the data stored in a next storage location is sequentially read when the data is read from the storage file next time. Here, the next storage position is a storage position adjacent to and behind the current storage position. For example, the first child thread reads the state value of the USB from the D1 location of the storage file when calling the read function for the first time, and the first child thread reads the state value of the USB from the D2 location of the storage file when calling the read function for the second time. The position D1 is adjacent to the position D2, and the position D2 is the next storage position of the position D1.

However, after the data monitoring module reads the state values of the USB at different times through the serial port data thread, the read state values of the USB are stored in a fixed storage location in the storage file. For example, after the data monitoring module acquires the state values of the USB at different times through the serial port data thread, the acquired state values of the USB are all stored in the storage location indicated by the first location pointer of the storage file. The storage position indicated by the first position pointer stores the state values of the USB at different times. For example, the storage location indicated by the first location pointer stores the USB status values read from the USB interface by the data snooping module at times T1, T2, and T3, respectively.

It should be explained that the storage location indicated by the first location pointer may be any location in the storage file, and the location of the storage location indicated by the first location pointer in the storage file is not limited herein.

Obviously, when the first sub-thread calls the read function multiple times to read the state values of the USB at different times from the storage file, the first sub-thread cannot acquire the state values of the USB at different times, which are stored in the storage location corresponding to the first location pointer of the storage file. Therefore, in the embodiment of the application, after the first sub-thread calls the read function each time to read the state value of the USB once from the storage location corresponding to the first position pointer of the storage file, the first sub-thread calls the read-write position control function once to return the first position pointer to the read-write function, so that the first sub-thread can also read the state value of the USB from the storage location indicated by the first position pointer when the first sub-thread calls the read-write function next time. The read-write position control function is used for controlling the first sub thread to read the state values of the USB at different moments from the same storage position of the storage file each time the read function is called. For example, the read/write position control function may be an lseek interface function.

The lseek function is also referred to as a random access file and is used to locate a file pointer to a corresponding location in a specified file descriptor. For example, after calling the read function each time to read the state value of the USB from the storage location corresponding to the first location pointer of the storage file, the first child thread may call the lseek function to locate the file pointer to the first location pointer of the storage file, so that the first child thread may read the state values of the USB at different times from the same location of the storage file.

In step 506, the data acquisition module sends the state value of the USB to the data processing module. Accordingly, the data processing module receives the state value of the USB.

Step 507, the data processing module judges whether the USB connection line between the mobile phone and the external device is disconnected according to the USB state value.

In the embodiment of the application, the data processing module may obtain a state value of the USB within a first preset duration, so as to determine whether the USB connection line between the mobile phone and the external device is disconnected according to the state value of the USB within the first preset duration.

In a first situation, if the state values of the USB within the first preset time period acquired by the data processing module are all the first preset values (for example, the first preset value is 0), the data processing module determines that the USB connection line between the mobile phone and the external device is in a disconnected state.

It should be explained that the USB connection line between the mobile phone and the external device is in a disconnected state, which means that the USB connection line between the mobile phone and the external device is pulled out, and the mobile phone and the external device are not connected through the USB connection line.

For example, the data processing module may obtain the state value of the USB in real time, and if the state values of the USB obtained by the data processing module within a duration of 3 seconds are all 0, the data processing module determines that the USB connection line between the mobile phone and the external device is in a disconnected state.

The first preset time period is taken as 3 seconds as an example, and of course, the first preset time period may also be 2 seconds, 3.5 seconds, 4 seconds, and the like, which is not limited herein.

In the second situation, if the state value of the USB acquired by the data processing module is a second preset value (for example, the second preset value is 1), the data processing module determines that the USB connection line between the mobile phone and the external device is in a connection state. Namely, the USB connecting line between the mobile phone and the external equipment is not pulled out by the tester. Under the condition, the data processing module continuously reads the state value of the USB so as to judge whether the USB connecting line between the mobile phone and the external equipment is disconnected or not according to the subsequently acquired state value of the USB.

That is to say, when the state value of the USB acquired by the data processing module is 1, the data processing module may determine that the USB connection line between the mobile phone and the external device is in a connection state. The data processing module continuously reads the state value of the USB until the state values of the USB acquired within the first preset time are all 0, and the data processing module determines that the USB connecting line between the mobile phone and the external equipment is in a disconnected state.

It should be explained that, when the data obtaining module obtains the state value of the USB from the storage file, there may be a case where the obtained USB state is unstable due to a jump of the state value of the USB between 0 and 1, that is, there may be a jump of the state value of the USB obtained by the data obtaining module between 0 and 1. In this case, in order to avoid the data processing module from misjudging the USB connection state between the mobile phone and the external device, in this embodiment of the application, after the data processing module acquires the USB state value sent by the data acquisition module, the data processing module may judge that the USB connection between the mobile phone and the external device is in the disconnected state according to the USB state value within the first preset time period.

Step 508, the shutdown module controls the mobile phone to shutdown.

In some embodiments, after the data processing module determines that the USB connection line between the mobile phone and the external device is in the disconnected state, the shutdown module may control the mobile phone to shutdown according to a shutdown instruction received by the mobile phone. For example, the shutdown module may call a shutdown instruction through a shutdown interface function (e.g., call the shutdown instruction through a shutdown interface function shutdown) to control the mobile phone to be powered off.

In other embodiments, after the data processing module determines that the USB connection line between the mobile phone and the external device is in the disconnected state, the mobile phone may prompt the user in a manner of sending a prompt message. For example, the mobile phone may send a prompt sound through the audio prompt module to prompt a tester that the USB connection line between the mobile phone and the external device is in a disconnected state, so that the tester manually controls the mobile phone to shut down. For example, the mobile phone may send a voice prompt in a voice prompt manner to "the mobile phone is disconnected", or the mobile phone may send a sound such as a buzzer to prompt the tester, so that the tester manually controls the mobile phone to shut down and then puts the mobile phone in storage, thereby ensuring that the battery power of the mobile phone is sufficient during the next test.

In summary, after the USB interface of the mobile phone receives the shutdown instruction sent by the external device, the data processing module determines that the state value of the USB acquired within the first preset time period is 0, and then determines that the USB connection line between the mobile phone and the external device is in the disconnected state, and then the shutdown module calls the shutdown instruction through the shutdown interface function to control the mobile phone to shutdown, or the shutdown module notifies a tester to manually control the mobile phone to shutdown. Therefore, the mobile phone is controlled to be powered off after the USB connecting line between the mobile phone and the external equipment is disconnected, and the problem that the mobile phone can be restarted immediately when the mobile phone is powered off but the USB connection is not disconnected due to the USB connection between the mobile phone and the external equipment is solved.

In the embodiment of the application, when the mobile phone is connected with the external device through the USB or the wireless network, after the external device sends the shutdown instruction to the mobile phone, if the USB or the wireless network connection between the mobile phone and the external device is not disconnected and the mobile phone is not shutdown, the external device may also send other instructions to the mobile phone.

For example, after the external device sends a shutdown instruction to the USB interface of the mobile phone, when the USB connection line between the mobile phone and the external device is not disconnected and the mobile phone is not shutdown, the external device may also send a data acquisition instruction to the USB interface of the mobile phone through the USB connection line. The data acquisition instruction is used for acquiring certain information in the mobile phone or controlling the mobile phone to execute an operation corresponding to the instruction. For example, the data acquisition instruction may be an instruction for acquiring information of a single board of a mobile phone, an instruction for calibrating a radio frequency antenna of the mobile phone, an instruction for performing a related test on a current of the mobile phone, or the like. After the external device sends a data acquisition instruction to the USB interface of the mobile phone, the mobile phone may determine whether the USB connection line between the mobile phone and the external device is disconnected according to whether the data acquisition instruction sent by the external device can be received.

The following takes the connection between the mobile phone and the external device through the USB connection line as an example, and the above process is explained in detail with reference to fig. 6, where fig. 6 is a schematic flow diagram of a shutdown method provided in this embodiment of the present application. As shown in fig. 6, the method may include the steps of:

step 601, the external device sends a shutdown instruction to the USB interface of the mobile phone. Correspondingly, the USB interface of the mobile phone receives a shutdown instruction.

Step 602, the external device sends a data acquisition instruction to the USB interface of the mobile phone. Correspondingly, the USB interface of the mobile phone receives the data acquisition instruction.

In this embodiment of the application, the execution processes of step 601 and step 602 are not limited, the external device may send a shutdown instruction to the USB interface of the mobile phone first, and then send a data acquisition instruction, that is, sequentially execute step 601 and step 602, the external device may also send a data acquisition instruction to the USB interface of the mobile phone first, and then send a shutdown instruction, that is, execute step 602 first and then execute step 601, and the external device may also send a shutdown instruction and a data acquisition instruction to the USB interface of the mobile phone simultaneously, that is, execute step 601 and step 602 simultaneously, where this is not limited.

Step 603, the data monitoring module monitors that the USB interface receives a shutdown instruction.

In step 604, the data monitoring module monitors whether the USB interface receives the data acquisition instruction within a second preset time period.

In the embodiment of the application, after the external device sends the data acquisition instruction to the USB interface of the mobile phone, the mobile phone may determine whether the USB connection line between the mobile phone and the external device is disconnected according to whether the USB interface receives the data acquisition instruction sent by the external device.

In a possible situation, if the data monitoring module of the mobile phone does not monitor that the USB interface receives the data acquisition instruction sent by the external device within a second preset time period during which the external device sends the data acquisition instruction, the mobile phone determines that the USB connection line between the mobile phone and the external device is disconnected.

In another possible situation, if the data monitoring module of the mobile phone monitors that the USB interface receives the data acquisition instruction sent by the external device within a second preset time period during which the external device sends the data acquisition instruction, the mobile phone determines that the USB connection line between the mobile phone and the external device is in a connection state.

In the embodiment of the application, when the data monitoring module reads the shutdown instruction from the USB interface through the serial port data thread, the mobile phone may obtain the data acquisition instruction sent by the external device through other threads. For example, the mobile phone obtains a data obtaining instruction sent by the external device through the second sub thread. The second sub-thread may be a thread executed in parallel with the serial port data thread. That is to say, the mobile phone can acquire various instructions sent by the external device in a multi-thread manner, thereby ensuring the stability of the external device in testing the mobile phone.

It should be noted that the external device sends the shutdown instruction to the mobile phone and sends the data acquisition instruction to the mobile phone in a multi-thread manner, for example, the external device may send the shutdown instruction and the instruction for acquiring the information of the single board of the mobile phone to the mobile phone through different threads. When one thread can not normally run, the running of other threads is not influenced, so that the stability of the mobile phone in the test process is ensured, and the data transmission efficiency is improved.

Step 605, the power-off module controls the mobile phone to power off.

In the embodiment of the application, after the mobile phone determines that the USB connection line between the mobile phone and the external device is disconnected, the shutdown module of the mobile phone calls the shutdown instruction to control the mobile phone to shutdown, or the mobile phone may prompt the user by sending a prompt message, so that the tester manually controls the mobile phone to shutdown. The second preset time period is not limited, and the second preset time period may be 2 seconds, 3 seconds, and the like.

Step 606, the data monitoring module sends a data acquisition instruction to the data acquisition module. Correspondingly, the data acquisition module receives the data acquisition instruction.

In step 607, the data obtaining module obtains information corresponding to the data obtaining instruction.

In step 608, the data obtaining module sends the information corresponding to the data obtaining instruction to the external device through the USB interface. Correspondingly, the external equipment receives information corresponding to the data acquisition instruction.

For example, it is assumed that the data obtaining instruction is an instruction for obtaining board information of a mobile phone, and after the data obtaining module obtains the data obtaining instruction, the data obtaining module may obtain the board information of the mobile phone according to the data obtaining instruction. And then, the data acquisition module sends the single-board information of the mobile phone to the external equipment through the USB interface. Correspondingly, the external equipment receives the single board information of the mobile phone.

In some embodiments, it is assumed that the data acquisition instruction acquired by the data acquisition module is an instruction for testing some performances of the mobile phone, and the mobile phone may test the mobile phone according to the data acquisition instruction. For example, assuming that the data acquisition instruction acquired by the data acquisition module is an instruction for testing a radio frequency antenna of a mobile phone, the mobile phone may test a video antenna of the mobile phone according to the instruction.

It should be noted that, in the above-mentioned fig. 6, the connection between the mobile phone and the external device is taken as an example, and the method in the above-mentioned fig. 6 is also applicable to the connection between the mobile phone and the external device through other manners, for example, the connection between the mobile phone and the external device is through a wireless network, which is not limited herein.

To sum up, after the mobile phone receives the shutdown instruction sent by the external device, the external device sends a data acquisition instruction to the mobile phone, and if the mobile phone does not receive the data acquisition instruction within the second preset time period, it is determined that the connection between the mobile phone and the external device is disconnected, and then the mobile phone is controlled to be shut down. Therefore, the mobile phone is controlled to be powered off after the connection between the mobile phone and the external equipment is disconnected, and the problem that the electric quantity of the mobile phone is exhausted due to storage and storage of the mobile phone without being powered off is solved.

In other embodiments, as shown in fig. 7, in a scenario where the mobile phone is connected to the external device through the wireless network, after a performance test of the mobile phone by the external device is completed, the external device sends a shutdown instruction to the mobile phone through the wireless network, and after determining that the mobile phone is shutdown, the tester stores the mobile phone in a storage.

For example, assume that the mobile phone and the external device are connected through a Wireless-Fidelity (WiFi), that is, the external device performs data transmission with the mobile phone through WiFi. For example, after the external device finishes the performance test of the radio frequency antenna of the mobile phone, the external device sends a shutdown instruction to the mobile phone through WiFi. After the mobile phone obtains the shutdown instruction, the mobile phone continuously monitors the WiFi signal, and the mobile phone determines whether the WiFi connection between the mobile phone and the external equipment is disconnected according to whether the WiFi signal is monitored. If the mobile phone does not monitor the WiFi signal, the WiFi connection between the mobile phone and the external equipment is determined to be disconnected, and the mobile phone is controlled to be powered off.

Next, taking a wireless network connection between the mobile phone and the external device as an example, the above process is explained in detail with reference to fig. 8, and fig. 8 is a third flowchart of the shutdown method provided in this embodiment of the present application. As shown in fig. 8, the method may include the steps of:

step 801, the external device sends a shutdown instruction to a WiFi communication interface of the mobile phone through WiFi.

Because the mobile phone is connected with the external equipment through WiFi, data are transmitted between the mobile phone and the external equipment through WiFi. In the embodiment of the application, when the external device controls the mobile phone to be powered off, the external device may send a power-off instruction to the mobile phone through the WiFi.

In step 802, the data monitoring module monitors that the WiFi communication interface obtains a shutdown instruction.

In step 803, the data monitoring module sends a data monitoring instruction to the data monitoring module. Correspondingly, the data monitoring module receives the data monitoring instruction.

The data monitoring instruction is used for indicating the data monitoring module to monitor WiFi signals in the mobile phone.

And step 804, the data monitoring module judges whether the WiFi connection between the mobile phone and the external equipment is disconnected according to whether the WiFi signals can be monitored.

It will be appreciated that the WiFi signal of the handset has its corresponding signal identification used to uniquely tag the WiFi signal. The data monitoring module can monitor various signals, and the data monitoring module can identify the WiFi signals from the various signals according to the signal identifications corresponding to the WiFi signals.

In the embodiment of the application, the data monitoring module can monitor the WiFi signal in the mobile phone in real time, and if the data monitoring module can monitor the WiFi signal in the mobile phone, it is determined that the WiFi connection between the mobile phone and the external device is not disconnected. And if the data monitoring module does not monitor the WiFi signal in the mobile phone, determining that the WiFi connection between the mobile phone and the external equipment is disconnected.

In order to avoid unstable WiFi signals in the mobile phone, the data monitoring module misjudges the WiFi connection state between the mobile phone and the external equipment. In the embodiment of the application, under the condition that the data monitoring module determines that the WiFi signal in the mobile phone is monitored within the third preset time period, the data monitoring module determines that the WiFi connection between the mobile phone and the external device is not disconnected. And the data monitoring module does not monitor the WiFi signal in the mobile phone within a third preset time length, and the disconnection of the WiFi connection between the mobile phone and the external equipment is determined. For example, if the data monitoring module does not monitor a WiFi signal in the mobile phone within 3 seconds, it is determined that the WiFi connection between the mobile phone and the external device is disconnected.

The third preset time period is not limited, and the third preset time period may be 2 seconds, 3 seconds, and the like.

In the embodiment of the application, when the data monitoring module reads the shutdown instruction from the WiFi communication interface through the serial port data thread, the data monitoring module may monitor the WiFi signal in the mobile phone through other threads. For example, the data monitoring module monitors a WiFi signal in the mobile phone through the third sub thread. The third sub-thread may be a thread executed in parallel with the serial port data thread. That is to say, the mobile phone can acquire data in a multi-thread manner, so that the efficiency and stability of data acquisition are improved.

In step 804, if the data monitoring module determines that the WiFi connection between the mobile phone and the external device is in a disconnected state, step 805 is executed, otherwise, the data monitoring module monitors a WiFi signal to determine whether the WiFi connection between the mobile phone and the external device is disconnected.

Step 805, the data monitoring module sends a shutdown instruction to the shutdown module. Correspondingly, the shutdown module receives a shutdown instruction.

In step 806, the shutdown module controls the mobile phone to shutdown according to the shutdown instruction.

In some embodiments, after the data monitoring module determines that the WiFi connection between the mobile phone and the external device is in a disconnected state, the data monitoring module sends a shutdown instruction to the shutdown module, so that the shutdown module controls the mobile phone to shutdown according to the shutdown instruction.

In other embodiments, after the data monitoring module determines that the WiFi connection between the mobile phone and the external device is in a disconnected state, the mobile phone may prompt a tester that the WiFi connection between the mobile phone and the external device is in a disconnected state through the audio prompting module, so that the tester manually controls the mobile phone to turn off. For example, the mobile phone may send a voice prompt in a voice prompt manner to "the mobile phone is disconnected", or the mobile phone may send a sound such as a buzzer to prompt the tester. Therefore, after the external equipment finishes testing certain performances of the mobile phone, the mobile phone is controlled to be powered off in a code and manual combination mode, and the production line efficiency is improved.

In the embodiment of the application, the mobile phone is connected with the external device through the WiFi, after the external device sends the shutdown instruction to the mobile phone, when the data monitoring module does not monitor the WiFi signal, it is determined that the WiFi connection between the mobile phone and the external device is disconnected, and then the shutdown module or a tester controls the mobile phone to shutdown. Therefore, data transmission is carried out between the mobile phone and the external equipment through WiFi connection, and the problem that the mobile phone can be restarted immediately when the mobile phone is powered off but the USB connection is not disconnected due to USB connection between the mobile phone and the external equipment is solved fundamentally. The mobile phone executes the shutdown operation after determining that the WiFi connection between the mobile phone and the external equipment is disconnected, so that the mobile phone is successfully shut down and then put in storage after the external equipment finishes testing the mobile phone, the labor is saved, and the shutdown efficiency of the mobile phone is improved.

The above description is made by taking WiFi connection as an example of the wireless network connection between the mobile phone and the external device. The shutdown method provided by the embodiment of the application can also be applied to other wireless network connection scenes. For example, the mobile phone and the external device may communicate with each other via bluetooth or ZigBee, which is not limited herein.

In summary, in the scheme provided in the embodiment of the present application, when the mobile phone is connected to the external device through the USB, and the data processing module determines that the state values of the USB acquired within the first preset time period are all the first preset values, it is determined that the USB connection line between the mobile phone and the external device is in the disconnected state, so that the problem of misjudgment on the connection state of the USB when the state value of the USB acquired by the data processing module jumps between the first preset value and the second preset value is avoided. Subsequently, the mobile phone calls a shutdown instruction or informs a tester to control the shutdown of the mobile phone, so that the mobile phone is controlled to be shut down and put in storage after the USB connection between the external equipment and the mobile phone is disconnected.

In addition, after the data processing module calls the file opening function to open the storage file through the first sub-thread, the reading function is called to read the stored state values of the USB at different moments from the storage file, and then the closing function is called to close the storage file. Therefore, the first sub-thread only calls the file opening function once to open the storage file, the problem that in the related technology, the memory of the mobile phone is greatly consumed because the storage file is opened once when the state value of the USB is read once is solved, and therefore the purpose that the file is opened once and the state value of the USB is read for many times is achieved.

In addition, when the mobile phone is connected with the external equipment through the USB or the wireless network, after the mobile phone receives a shutdown instruction sent by the external equipment, if the mobile phone does not receive the data acquisition instruction within a second preset time period, the USB connection or the wireless network connection between the external equipment and the mobile phone is determined to be in a disconnected state, then the mobile phone calls the shutdown instruction or informs a tester to control the mobile phone to shutdown, so that the mobile phone is controlled to be shut down and put in storage after the USB connection or the wireless network connection between the external equipment and the mobile phone is disconnected, and the problem that the battery power is exhausted due to the fact that the mobile phone is not shut down and put in storage is solved.

In addition, when data are transmitted between the mobile phone and the external equipment through wireless network connection, the mobile phone does not monitor a wireless network signal within a third preset time period, the disconnection of the wireless network connection between the mobile phone and the external equipment is determined, then the mobile phone is controlled to be shut down and put in storage, the mobile phone is successfully shut down and put in storage after the external equipment finishes testing the mobile phone, manpower is saved, and the efficiency of shutting down the mobile phone is improved.
