Detailed Description
To make the purpose, technical solutions and advantages of the disclosed examples clearer, the technical solutions in the disclosed examples will be clearly and completely described below with reference to the drawings in the disclosed examples.
The rapid development of the internet of things promotes the generation of massive internet of things terminal products. The internet of things terminals exhibit various characteristics including wireless transmission technology, frequency bands and various forms according to different applications. The internet of things terminal is in a fragmentization state at present, and different detection mechanisms do not have a uniform industrial standard when testing various internet of things terminals.
The existing internet of things terminal detection methods comprise the following three methods:
1) reading SIM card information in a tested terminal, detecting whether the SIM card information can be successfully read, if so, starting the tested terminal and accessing a test network for testing; and if the terminal receives the access signaling in the access process, the communication capability of the terminal is considered to be qualified.
2) The module applied to the narrow-band Internet of things terminal is detected, and the radio frequency consistency and the protocol consistency of the module are detected so as to verify whether the module meets the 3GPP protocol requirements or not.
3) The method comprises the steps that equipment initiates a login request to send a CONNECT message, an Internet of things communication platform (IOT HUB for short) receives the equipment request, a getDeviceInfo interface (equipment query) of the platform is called to check whether equipment information is in an equipment data table, connection is refused if the equipment information does not exist, the IOT HUB sends a CONNACK message to the equipment if the equipment information exists, and the equipment login is successful.
However, in the above method, it is detected that the communication capability of the terminal and the protocol consistency of the platform or the module are consistent, but the network access problem may occur again after the terminal is reset in the actual use process of the terminal, the cell reselection problem that may occur when the terminal is located within the coverage area of two adjacent cells, and the network access problems of the terminal, such as the stability of the terminal receiving and sending services, the terminal receiving sensitivity, and the like, are not systematically tested. In addition, one of the characteristics of the terminal of the internet of things is low power consumption, so that power consumption verification aiming at the terminal is indispensable, and in the existing testing method, the testing aiming at the network access capability of the terminal does not involve a power consumption testing part. That is to say, the existing testing method is not matched with the actual use requirement of the terminal, so that the problems of frequent offline and low service life of the terminal product in the actual use process can also occur.
Aiming at the problem, the disclosure provides a terminal performance testing method and a system, so as to solve the problem that the actual use performance of the terminal cannot be accurately measured by the existing testing method.

In addition, before the above example is executed, a terminal test environment that can be used for executing the above example needs to be built, as shown in fig. 2, in a wireless network environment provided based on a base station 1, a base station signal is respectively input into two shielding boxes 3 through a signal attenuator, wherein 900M two paths of base station signals can be accessed into one shielding box 3, 1800M two paths of base station signals can be accessed into the other shielding box 3, and the signal strength in the shielding box 3 is adjusted by adjusting the signal attenuator 2, so that different wireless network environments are simulated.
Specifically, the data interface arranged on the shielding box 3 can be a USB port, in the terminal testing process, a serial port and a debug port of the testing terminal are developed, and the testing terminal is connected with the server through the USB port on the shielding box 3, so that it is ensured that the log of the testing terminal can be read by the server 4 after the testing terminal is placed in the shielding box, and an Attention instruction (Attention, referred to as AT for short) issued by the server 4 to the terminal can be reached, and therefore, the testing terminal can be controlled by inputting a corresponding AT instruction on the server 4 by an operator.
Secondly, after the post-test environment is set up, the test environment needs to be debugged to meet certain conditions, so that the test result is more accurate. The conditions include:
1) the basic functions of the test terminal are normal, the environment of the base station and the application platform is normal, wherein the application platform is a platform capable of receiving the heartbeat of the terminal or reporting the service data, and preferably, when the test terminal is a narrow-band Internet of things terminal, the application platform is an NB-IOT platform;
2) the uplink background noise of the cell is lower than-130 dbm;
3) the environment of the shielding box is an ideal background noise environment.
The terminal performance testing method provided by the disclosed example comprises the steps of sending at least one testing signal to at least one testing terminal in a shielding device through a signal attenuator outside the shielding device; according to a preset test task, the at least one test terminal responds to the at least one test signal and sends a test log to a server through a data interface arranged on the shielding device so that the server can generate a test report of the at least one test terminal according to the test log; wherein the preset test tasks include one or more of the following tests: the method comprises the steps of automatic network access testing, service connectivity testing, radio frequency sensitivity testing, cell reselection function testing, clock synchronization testing and power consumption testing, and can be matched with the actual use requirements of the terminal and effectively measure the performance levels of the terminal of the Internet of things in the actual use process.
On the basis of the above example, fig. 3 is a schematic flow chart of a terminal performance testing method provided in example two of the present disclosure, and when the preset test task is an automatic network access test, as shown in fig. 3, the method includes:
step 201, setting the state of the at least one test terminal as a working state.
The working state means that the test terminal is successfully attached to the network, and the heartbeat data is normal in an uplink mode.
Specifically, the strength of a test signal in the shielding box is adjusted through the signal attenuator, so that the test terminal can successfully access the network, the time interval of heartbeat reporting data of the test terminal is set, and when the test terminal is successfully accessed to the network and the heartbeat data goes upward normally, the test terminal is in a working state.
Step 202, adjusting the attenuation value of the signal attenuator, so that the signal intensity of the at least one test signal is attenuated from a first intensity value to a second intensity value, and then is increased from the second intensity value to the first intensity value.
The first strength value is greater than the lowest strength value of the access signal of the test terminal, and the second strength value is less than the lowest strength value.
Step 203, collecting first heartbeat data of the test terminal in the strength change process of the test signal, and sending a test log including the first heartbeat data to the server.
In this example, the attenuation value of the signal attenuator is adjusted to attenuate the signal intensity of the test signal from the first intensity value to the second intensity value, at this time, the terminal is disconnected from the network and the heartbeat uplink is stopped, then the attenuation value of the signal attenuator is adjusted to increase the signal intensity of the test signal from the second intensity value to the first intensity value again, whether the terminal can automatically re-enter the network for attachment or not and whether the heartbeat uplink can be recovered to be normal or not are observed, and when the terminal is successfully attached to the network and the heartbeat is recovered to be normal, the terminal is passed through the test.
Taking the application to the terminal test environment set up in fig. 2 as an example, the test terminal is placed in a shielding box, and the reporting time interval of the modified terminal data (heartbeat/service) is 2-5 min; adjusting the network signal intensity in the shielding box to-75-90 dBm, meeting the terminal network access attachment condition, and observing whether the terminal network access attachment is successful; after the observed terminal is successfully attached to the network and the heartbeat is normally reported, adjusting the strength of the network signal accessed by the terminal equipment in the shielding box until the terminal is detached from the attachment/offline; then gradually restoring the network signal intensity to an initial range, observing whether the terminal can automatically access the network for attachment, and whether the subsequent heartbeat can be restored; if the network signal can be automatically accessed after being reset and the heartbeat can be recovered, the automatic network access is considered to be successful after the signal is reset.
The terminal performance testing method provided by the disclosed example sets the state of the at least one testing terminal as a working state; adjusting an attenuation value of the signal attenuator to attenuate a signal strength of the at least one test signal from a first strength value to a second strength value, wherein the first strength value is greater than a lowest strength value of an access signal of the test terminal, and the second strength value is less than the lowest strength value; the method comprises the steps of collecting first heartbeat data of the test terminal in the strength change process of the test signal, sending a test log comprising the first heartbeat data to the server, detecting the possible disconnection of the terminal in the actual use process due to the network signal deterioration, and improving the reliability of the terminal in the network re-accessing process due to the network signal strength change after the network signal is recovered.
On the basis of the example shown in fig. 1, fig. 4 is a schematic flowchart of a terminal performance testing method provided in the third example of the present disclosure, and when the preset test task is an automatic network access test, as shown in fig. 4, the method includes:
step 301, adjusting the attenuation value of the signal attenuator to make the signal strength of the at least one test signal be a first strength value.
Wherein the first strength value is greater than the lowest strength value of the access signal of the test terminal.
And 302, setting the state of the at least one test terminal to be a working state and a reset state in sequence.
Specifically, the working state means that the test terminal is successfully attached to the network, and the heartbeat data is normal in an uplink mode; the reset state comprises the operation of power failure and reset of the terminal, and the terminal can be issued through an AT instruction.
And 303, collecting second heartbeat data when the state of the test terminal is set to be a working state and a reset state in sequence, and sending a test log comprising the second heartbeat data to the server.
Specifically, the test terminal is set to be in a working state, namely after the successful network access attachment of the terminal is observed and the heartbeat data report is normal, the test terminal is set to be in a reset state, namely, the power-down operation is firstly carried out on the terminal, when the terminal is observed to be disconnected from the network and the heartbeat data stops reporting, the reset operation is carried out, whether the terminal can automatically re-access the network or not is observed, whether the heartbeat uplink is normal or not is observed, and when the successful network access attachment of the terminal and the heartbeat recovery are normal, the terminal is indicated to be passed through the test.
Taking the application to the terminal test environment set up in fig. 2 as an example, the test terminal is placed in a shielding box, and the reporting time interval of the modified terminal data (heartbeat/service) is 2-5 min; adjusting the network signal intensity in the shielding box to-75-90 dBm, meeting the terminal network access attachment condition, and observing whether the terminal network access attachment is successful; after the observed terminal is successfully attached to the network and the heartbeat is normally reported, resetting the terminal (the resetting action comprises power failure, resetting and the like); whether the terminal can automatically access to the network for attachment is observed, and whether the subsequent heartbeat can be recovered; if the terminal can automatically access the network and the heartbeat can be recovered after the terminal is reset; the automatic network access is considered to be successful after the terminal is reset.
The terminal performance testing method provided by the disclosed example enables the signal strength of the at least one test signal to be a first strength value by adjusting the attenuation value of the signal attenuator, wherein the first strength value is greater than the lowest strength value of the access signal of the test terminal; setting the state of the at least one test terminal to be a working state and a reset state in sequence; the method comprises the steps of collecting second heartbeat data when the test terminal is set to be in a working state and a reset state in sequence, sending a test log comprising the second heartbeat data to the server, detecting whether the terminal can automatically re-access the network after being reset after the terminal is disconnected due to terminal power failure and the like possibly occurring in the actual use process, and improving the reliability of re-accessing the network after the terminal is reset in the actual use process.
On the basis of the example shown in fig. 1, fig. 5 is a flowchart illustrating a terminal performance testing method provided in the fourth example of the present disclosure, and when the preset testing task is a service connectivity test, as shown in fig. 4, the method includes:
step 401, setting the state of the at least one test terminal as a working state, and adjusting the attenuation value of the signal attenuator to make the signal strength of the at least one test signal be a first strength value.
Wherein the first strength value is greater than the lowest strength value of the access signal of the test terminal.
Step 402, controlling the test terminal to perform service triggering by using the wireless network provided by the at least one test signal, and uploading application data to a service platform through the wireless network, so that the service platform sends a test log including the application data to the server.
In this example, the attenuation value of the signal attenuator is adjusted to make the signal intensity of the test signal be a first intensity value, after successful network access attachment of the terminal and normal heartbeat uplink are observed, the service triggering is performed on the terminal side, whether corresponding application data are reported or not is observed on the application platform side, and when the terminal is observed to be capable of automatically network access attachment and normal heartbeat is observed; and after the terminal side service is triggered, the application platform side receives the application data report, and the service connectivity test is considered to pass.
Taking the application to the terminal test environment set up in fig. 2 as an example, the test terminal is placed in a shielding box, and the terminal is successfully registered on the application platform, so that the application platform can identify and analyze data sent by the terminal; modifying the reporting time interval of terminal data (heartbeat/service) to be 2-5 min; adjusting the network signal intensity in the shielding box to-75-90 dBm, meeting the terminal network access attachment condition, and observing whether the terminal network access attachment is successful; after the observed terminal is successfully attached to the network and the heartbeat is normally reported, the terminal side is triggered by business and observes whether corresponding application data are reported or not on the application platform side; if the terminal can automatically access the network and the heartbeat is normal, and the application platform side receives the application data report after the service of the terminal side is triggered; the traffic connectivity test is deemed to pass.
The terminal performance testing method provided by the example of the present disclosure sets the state of the at least one testing terminal as a working state, and adjusts the attenuation value of the signal attenuator to make the signal strength of the at least one testing signal be a first strength value, where the first strength value is greater than the lowest strength value of the access signal of the testing terminal; and controlling the test terminal to utilize the wireless network provided by the at least one test signal to trigger the service, and uploading application data to the service platform through the wireless network so that the service platform sends a test log comprising the application data to the server, thereby detecting whether the terminal can normally send the data to the platform and ensuring that the service of the terminal can be reached in the actual use process.

step 503, collecting the states of the test terminal under different signal strengths, and sending a test log including the signal strength and the corresponding state to the server, so that the server determines the lowest strength value of the test terminal according to the test log.
In this example, the attenuation value of the signal attenuator is adjusted to make the test signal strength in the shielding box reach the first strength value, and it is observed whether each test terminal successfully accesses the network and the heartbeat data goes up normally, i.e. whether the test terminal is in a working state, when it is observed that each test terminal can normally report data under the network coverage condition, the signal strength in the shielding box is gradually reduced at a preset strength attenuation interval, and the lowest access level of the terminal is determined.
Optionally, after the lowest access level of the test terminal is determined, whether a packet loss phenomenon does not occur when the test terminal continuously sends a plurality of data packets is determined; and if the terminal can be attached to the network and the heartbeat is normal, and the condition that a plurality of packets of data continuously generated by the terminal are not lost is avoided, determining that the lowest access level of the terminal is the lowest intensity value.
In addition, in order to ensure the consistency of the radio frequency sensitivity of the terminals in the same batch and prevent the test error caused by random sampling, a plurality of test terminals can be put into the shielding box.
Taking the application to the terminal test environment set up in fig. 2 as an example, 1 semi-finished terminal and 5 finished terminals with serial ports and DEBUG ports opened are simultaneously placed in a shielding box; modifying the reporting time interval of 6 terminal data (heartbeat/service) to 2-5 min; adjusting the network signal intensity in the shielding box to about-115 dBm, and observing whether the 6 terminals are successfully attached to the network and the heartbeat (service) data is normal in uplink; if 6 terminals can normally report data under the network coverage condition, 1-5dB is taken as a step length to downwards reduce signal coverage in a shielding box, and whether the 6 terminals successfully access to the network and successfully attach and heartbeat (service) data are normally uplink is observed in real time until the lowest access level value of the terminals is confirmed.
After the lowest access level of the terminal is determined, testing the stability of 6 terminals continuously transmitting 15 packets of data on the basis; if 6 terminals can be attached to the network and the heartbeat is normal, and no packet loss occurs when 15 packets of data continuously occur in 6 terminals; the lowest access level of the terminal is determined to be the lowest access level of the terminal that is finally measured, i.e. the lowest strength value.

On the basis of the example shown in fig. 1, fig. 8 is a schematic flowchart of a terminal performance testing method provided in a seventh example of the present disclosure, and when the preset test task is a clock synchronization test, as shown in fig. 7, the method includes:
step 701, setting the state of the at least one test terminal to be a working state and a reset state in sequence;

On the basis of the example shown in fig. 1, fig. 9 is a schematic flowchart of a terminal performance testing method provided in an eighth example of the present disclosure, and when the preset test task is a terminal power consumption test, a power supply device connected to a test terminal is further disposed in the shielding device, and the power supply device is configured to supply power to the test terminal, as shown in fig. 9, the method includes:
step 801, setting the state of the test terminal to a working state, an idle state and a dormant state in sequence.
And 802, acquiring current consumption data of the test terminal in different states by using the power supply device, and sending a test log comprising the current consumption data to a server through the test terminal.
In this example, the power supply device may adopt a dc power supply analyzer, which can provide a dc power supply voltage of 0V-20V, and can meet the power supply requirements of the terminals of the internet of things in most networks.
Taking the application to the built terminal test environment as an example, firstly, adjusting the signal intensity of a cell in a shielding box; powering up the tested terminal and starting testing; the test terminal initiates a registration process, successfully attaches to a network, and enters a working state; the terminal releases RRC connection, enters an idle state, waits T3324 overtime and enters a dormant state; waiting for the next heartbeat cycle to arrive, and repeating at least 10 heartbeat cycles; after the current waveform is stable, respectively recording the current consumption conditions of the terminal in a working state, an idle state and a dormant state; and calculating the power consumption consumed by one heartbeat packet according to the power consumption of one heartbeat cycle, namely the working state power consumption, the idle state power consumption and the dormant state current, namely the dormant state time, and estimating the service life of the terminal according to the total capacity of the battery.
Specifically, the working state is a state in which the terminal can transmit data, the terminal is in the state immediately after registering to access the network, the terminal can transmit and receive data, an inactivity timer is triggered after no data interaction, and the time of the working state is the time taken for transmitting data plus the time set by the inactivity timer (for example, the current network setting is 20 s).
When the inactivity timer is overtime, the terminal enters an idle state, which is a monitoring state that the terminal enters after sending data, and triggers a T3324 timer, and in this state, the terminal still monitors whether the network pages itself within a period of time, and once the terminal monitors the network, the terminal immediately returns to a working state and starts to receive and send data. The time of the idle state is equal to the time set by the T3324 timer (for example, the current network setting is 10 s).
If there is no data interaction request in the monitoring process, the terminal enters the dormant state after the T3324 timer is overtime. In this state, the terminal will turn off the transceiver, and does not monitor the paging of the wireless side, and the downlink is not accessible, similar to the power-off state, so the power can be very small. The time of the sleep state is the heartbeat time interval or the service triggering time of the terminal, and it should be noted that the duration of the sleep state of each type of terminal is different and is set by the terminal manufacturer.
According to the terminal performance testing method provided by the embodiment of the disclosure, the state of the testing terminal is sequentially set to be a working state, an idle state and a dormant state, the power supply device is utilized to collect current consumption data of the testing terminal in different states, and a testing log including the current consumption data is sent to a server through the testing terminal. The theoretical service life of the terminal is evaluated by detecting the current consumption condition of the terminal in different network states and combining the battery power of the terminal, so that reference is provided for a user when the terminal is selected.
It should be noted that, in a plurality of test scenarios such as the automatic network access test, the service connectivity test, the radio frequency sensitivity test, the cell reselection function test, the clock synchronization test, the power consumption test, and the like described in the above examples, any two or more test scenarios may be coupled, that is, after the terminal completes the test in one test scenario, the terminal automatically enters another test scenario to perform the test.
