All other embodiments, based on the embodiments herein, which are within the scope of the protection of the present application, will be within the purview of one of ordinary skill in the art without the exercise of inventive faculty.
Example 1
The detection method of TBOX provided by the application can be applied to an application environment shown in figure 1. The detection equipment is connected with the signal conversion device through a USB bus, detection software matched with the signal conversion device is installed on the detection equipment, and the signal conversion device is connected with the TBOX to be detected through a CAN/LIN bus. The detection device can be, but is not limited to, various personal computers, notebook computers and other devices; the signal conversion device is a device capable of performing USB-CAN/LIN signal conversion, as shown in an internal structure block diagram of an example of the signal conversion device in fig. 2, the signal conversion device comprises a control chip MCU, a CAN transceiver, a LIN transceiver, a USB interface for connecting detection equipment and a CAN/LIN interface for connecting TBOX, LIN communication master-slave switching of the signal conversion device CAN be realized by a jumper wire mode, and the CAN/LIN interface is also connected with the control chip MCU through a power circuit and CAN provide power for the signal conversion device; the TBOX to be tested can be TBOX in different stages such as a development stage, a production stage, an experiment stage or an after-sales stage, and the detection requirements corresponding to the different stages are different.
As shown in fig. 3, an embodiment of the present application provides a method for detecting TBOX, which is described by taking application of the method to the detection apparatus in fig. 1 as an example, and includes the following steps:
in step 202, the detection device displays a login interface through detection software.
The detection software is software matched with the signal conversion device, and the login interface may be an interface for a user to input account information of the user to use the detection software, for example, an exemplary diagram of the login interface shown in fig. 4.
Specifically, the detection device may be connected to the TBOX to be detected through the signal conversion device, and the login interface is displayed through detection software matched with the signal conversion device.
In some embodiments, before step 202, the detection device may identify the hardware identification information of the signal conversion device by detecting the software, and display a login interface corresponding to the hardware identification information, so as to accurately provide a login interface matched with the signal conversion device, so that accurate matching with different types of signal conversion devices may be achieved, and the method has good expansibility. At this time, the internal memory of the signal conversion device is solidified with a piece of hardware identification information (such as a hardware code, a hardware model, etc.), and the hardware identification information can be used for the detection device to distinguish different types of signal conversion devices, so that the signal conversion device can be identified and matched quickly.
Specifically, after the detection equipment is connected with the signal conversion device through the USB bus, the detection equipment tries to establish communication connection with the signal conversion device, if the detection equipment successfully establishes communication connection with the signal conversion device, the detection equipment can identify hardware identification information of the signal conversion device through detection software, and after the hardware identification information is obtained, a login interface corresponding to the hardware identification information is displayed, and the displayed login interface is a login interface matched with the signal conversion device; otherwise, if the detection equipment fails to establish communication connection with the signal conversion device, the connection failure is displayed.
Step 204, obtaining user account information input by the user on the login interface, and determining a target operation mode corresponding to the user according to the user account information.
The user account information may include a user account and a password corresponding to the user account; the user-corresponding target operating mode may be any of a pre-configured plurality of operating modes, each of the plurality of operating modes corresponding to a stage in the TBOX product lifecycle, one operating mode being capable of performing all of the detection operations required for its corresponding stage, for example: the TBOX product lifecycle may be divided into a development phase, a production phase, an experimental phase, an after-market phase, and the like, and accordingly, the preconfigured plurality of operating modes may include, but are not limited to, one or more of a development phase operating mode, a production phase operating mode, an experimental phase operating mode, and an after-market phase operating mode.
Specifically, the target operation mode corresponding to the user can be set and modified according to actual needs. Considering that in a specific application scenario, the participants of TBOX in different detection phases are generally different, each user typically corresponds to only one mode of operation, for example: and the detection device judges that the target operation mode corresponding to the user A is a development stage operation mode according to the user account information after acquiring the user account information input by the user A on the login interface, and only loads the operation interface corresponding to the development stage operation mode.
In some embodiments, step 204 specifically includes the steps of: and acquiring user account information input by a user on a login interface, verifying the user account information, calling mapping relation data between preset user account information and an operation mode when the user account information passes verification, and determining a target operation mode corresponding to the user according to the mapping relation data.
The mapping relation data between the user account information and the operation mode can be stored in an internal memory of the detection equipment, and can also be stored in a network server externally connected with the detection equipment; in the specific implementation process, the user account information is verified, that is, the user account and the password corresponding to the user account are usually verified, for example, whether the user account exists, whether the password corresponding to the user account is correct, and the like.
Step 206, displaying an operation interface corresponding to the target operation mode, wherein the operation interface includes a plurality of operation items executable in the target operation mode.
The operation interfaces corresponding to different operation modes are different, each operation interface comprises a plurality of operation items which can be executed in the corresponding operation mode, and the operation items are detection options which can be executed by a user in a target operation mode. Because the detection requirements of the TBOX in different stages are different, the detection items required to be carried out in different stages are different, and various operation items contained in the operation interface may overlap, change or increase under different operation modes so as to meet the detection requirements of different stages. An example of an operator interface is shown in fig. 5.
Specifically, the detection device loads/invokes the operation interface corresponding to the target operation mode through detection software and displays the operation interface on the display device of the detection device, and as only the operation interface corresponding to the target operation mode is displayed for each user, the operation interface seen by the user is simpler and clearer, and the selection by the user is facilitated.
Step 208, obtaining a target operation instruction corresponding to an operation item to be executed, which is selected by a user from a plurality of operation items, and sending the target operation instruction to a signal conversion device, so that the signal conversion device converts the target operation instruction into an operation instruction which can be identified by the TBOX, wherein the operation instruction is used for indicating the TBOX to detect the TBOX according to the operation item to be executed so as to obtain original detection data, and the signal conversion device converts the original detection data into detection data which can be identified by the detection equipment.
The target operation instruction is an operation instruction corresponding to the selected operation item to be executed, and may be, but not limited to, a query instruction, a data acquisition instruction, or a parameter setting instruction.
Specifically, the user may select an operation item to be executed from a plurality of operation items included in the operation interface, and confirm execution, and at this time, the detection device receives a target operation instruction corresponding to the operation item to be executed. In specific implementation, a user can select a single operation item to perform single-item detection on the TBOX through the detection device, or can select a plurality of operation items to perform multiple-item detection on the TBOX at the same time.
Step 210, obtaining detection data from the signal conversion device, and analyzing the detection data to obtain a detection result of detecting the TBOX according to the operation item to be executed.
Specifically, the detection device obtains the detection data which can be identified from the signal conversion device, and analyzes the detection data to obtain a detection result of detecting the TBOX according to the operation item to be executed. In the actual operation process, the detection device may store the detection result, and may also display the detection result.
The embodiment provides a TBOX detection method, which is applied to detection equipment, wherein the detection equipment is connected to a TBOX to be detected through a signal conversion device, and detection software matched with the signal conversion device is installed on the detection equipment; the detection equipment displays a login interface through detection software, then obtains user account information input by a user on the login interface, determines a target operation mode corresponding to the user according to the user account information, displays an operation interface corresponding to the target operation mode, obtains a target operation instruction corresponding to an operation item to be executed, which is selected by the user from a plurality of operation items, and sends the target operation instruction to a signal conversion device, so that the signal conversion device converts the target operation instruction into an operation instruction which can be identified by TBOX, the operation instruction is used for indicating the TBOX to detect the TBOX according to the operation item to be executed so as to obtain original detection data, and the signal conversion device converts the original detection data into detection data which can be identified by detection equipment; the detection device acquires detection data from the signal conversion device, and analyzes the detection data to obtain a detection result of detecting the TBOX according to the operation item to be executed. In this embodiment, the detection device only needs to load the target operation mode corresponding to each user, so that each user only enters the corresponding target operation mode after logging in, and does not need to load all operation modes in the test software, so that the data volume required to be loaded by the detection device can be reduced, the calculation pressure of the detection device is reduced, the test efficiency of TBOX is improved, the hardware requirement on the detection device is reduced, and the cost can be reduced.
