[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0022] The following will describe the device testing method and device of the present invention in conjunction with Figures 1 to 4 Describe the device testing method and device of the present invention.

[0023] As Figure 1 shown, the present invention provides a device testing method, which includes the following steps 110 to 150.

[0024] Step 110: Obtain a test script file.

[0025] It is understandable that, as Figure 2 shown, the execution subject of the device test method can be a control and display test platform, which can be communicatively connected to a database and simultaneously communicatively connected to a TCS device. The control and display test platform is used to test whether the interaction function between the TCS device and the control and display is normal.

[0026] It should be noted that the control and display mainly communicates with the TCS device, receives real-time station field change information, operation prompts, and alarm information from the TCS device; the control and display can send button command information to the TCS device to complete the text and language output of the station field graphic display, operation prompts, and alarm information on the console, mouse operation, and button information processing, etc.

[0027] The TCS device can interact with the control and display. The device test method provided by the present invention is to simulate the control and display through the control and display test platform to test whether the TCS device can correctly respond to the command data related to the control and display.

[0028] The test script file can be a test case program pre-written by a staff member, which can be a computer-executable program file and can be stored in the database.

[0029] As Figure 2 shown, the control and display test platform can include a test manager, which can perform logical operation operations and execute the test script file.

[0030] The test manager can be communicatively connected to the database and can obtain the test script file from the database.

[0031] Step 120: Run the test script file to obtain control and display command data and expected execution data.

[0032] It is understandable that the test manager can run the test script file and output the control and display command data and the expected execution data. The control and display command data is a data form used to drive the TCS device to execute control and display actions, and the expected execution data is the data that the TCS device will feedback to the test manager when the control and display command data is normally executed, that is, a data form in a theoretical sense and an expected value.

[0033] Step 130: Send the control and display command data to the TCS device for the TCS device to run the control and display command data and obtain feedback execution data.

[0034] It can be understood that the control and display test platform can send control and display command data to the TCS device, and the TCS device can execute the control and display command data. After executing the control and display command data, feedback execution data will be obtained, and the TCS device can send the feedback execution data to the control and display test platform.

[0035] Step 140: Receive the feedback execution data.

[0036] It can be understood that the control and display test platform can receive the feedback execution data from the TCS device.

[0037] Step 150: Determine the test result of the TCS device based on the feedback execution data and the expected execution data.

[0038] It can be understood that the feedback execution data is the actual value obtained by the TCS device executing the control and display command data, while the expected execution data is the theoretical output value corresponding to the control and display command data being executed by the TCS device under normal circumstances. By comparing the feedback execution data and the expected execution data, the test result of the TCS device can be obtained.

[0039] For example, the difference between the feedback execution data and the expected execution data can be calculated to see if the calculation result is 0, or division can be done to see if the calculation result is 1, so as to determine whether the feedback execution data and the expected execution data are consistent. If they are not consistent, it can be considered that the control and display test fails. If they are consistent, it can be considered that the control and display test is successful.

[0040] Of course, there can be a normal error between the feedback execution data and the expected execution data. As long as the gap between the feedback execution data and the expected execution data is within the normal error range, it is considered that the control and display test is successful.

[0041] After the TCS signal device is developed, it needs to be tested by the control and display test platform. Existing control and display test platforms are often relatively specific and have poor versatility, and cannot implement the test work of existing TCS signal devices. In order to solve the problem of testing TCS signal devices, the present invention has developed a set of control and display test software, which can send data to the TCS signal device according to the TCS and control and display communication interface protocol. At the same time, this software can receive the data sent by the TCS device and make a judgment on its operation result to achieve the test function.

[0042] In the urban rail transit CBTC system, the integration of ZC and CI has become the trend of the development of contemporary rail transit signal systems. TCS can achieve the integration of ZC and CI, and joint commissioning and testing are imminent. As an important part of the test process, the control and display test platform can timely detect the ZC device, CI device and train status, providing a favorable guarantee for discovering problems in the test process.

[0043] The current control and display test platform mainly consists of five parts, including interfaces, power supplies, monitoring, interlocking operations, and human-machine interfaces. The specific implementation process relies on interface devices to collect TCS information, perform internal operations on it, and finally display it through the human-machine interface for testers to view.

[0044] However, with the increase in the number of trains and the increase in test difficulty, the current control and display test platform has technical defects. One is the high difficulty of fault recovery, and the other is the large number of repeated test operations and low test efficiency.

[0045] With the increase in the number of urban rail transit lines, the test difficulty will also increase. When the hardware and software are not stable enough, it is easy to have situations such as system crashes and faults. At the same time, the signal devices to be tested may have problems, resulting in faults in the control and display test platform. When a fault occurs, testers can only find the cause of the fault through the human-machine interaction interface, but cannot accurately locate the cause. The present invention can find the problem according to specific interaction information and recorded log files.

[0046] In the case of few testers and high test difficulty, testers need to repeatedly operate according to the human-machine interface to implement the test of TCS devices. However, the repeated operation process of testers may lead to test errors, reducing test efficiency. Moreover, test errors are not allowed for signal systems with a high safety factor. The present invention can write test cases by writing test script files. Running the test script file successfully proves that the test case passes, and if it fails, the reason can be found according to the generated log, reducing the occurrence of test errors. At the same time, the test cases can be repeatedly used in the same scenario, greatly improving test efficiency.

[0047] The device test method provided by the present invention obtains a test script file, automatically runs the test script file to obtain control and display command data and expected execution data. After the TCS device runs the control and display command data, feedback execution data can be obtained. Based on the feedback execution data and the expected execution data, the test result of the TCS device can be obtained, which can reduce the probability of test errors, avoid safety accidents, and improve test efficiency.

[0048] In some embodiments, the above step 130 of sending the control and display command data to the TCS device includes: identifying the control and display command data through the main engine and sending the control and display command data to the corresponding control and display sub-engines; sending the control and display command data to the TCS device through the control and display sub-engines.

[0049] It can be understood that, as Figure 2As shown, the control and display test platform may further include a main engine and a control and display sub-engine. The test manager may transfer the control and display command data to the main engine, and the main engine may identify the control and display command data and send the control and display command data to the corresponding control and display sub-engine.

[0050] The main engine may be connected to multiple sub-engines. Here, the function of interacting with the control and display is being tested, that is, sending the control and display command data to the corresponding control and display sub-engine.

[0051] The control and display sub-engine then sends the control and display command data to the TCS device.

[0052] In some embodiments, packing and sending the control and display command data to the TCS device through the control and display sub-engine includes: packing the control and display command data in accordance with the TCS interface specification format through the control and display sub-engine to obtain a control and display output data packet; sending the control and display output data packet to the TCS device through the control and display sub-engine.

[0053] It can be understood that the control and display sub-engine can parse and pack the control and display command data. Specifically, the control and display command data can be packed in accordance with the TCS interface specification format, so that a control and display output data packet can be obtained. The control and display sub-engine can send the control and display output data packet to the TCS device.

[0054] In some embodiments, step 150 above, determining the TCS device test result based on the feedback execution data and the expected execution data, includes: comparing the feedback execution data and the expected execution data. If the expected execution data and the feedback execution data are consistent, then output a test success message;

[0055] Or, if the expected execution data and the feedback execution data are inconsistent, then output a test failure message.

[0056] The difference between the feedback execution data and the expected execution data can be calculated to see if the calculation result is 0, or division can be done to see if the calculation result is 1, so as to determine whether the feedback execution data and the expected execution data are consistent.

[0057] If they are inconsistent, it can be considered that the control and display test fails, and then output a test failure message.

[0058] If they are consistent, it can be considered that the control and display test is successful, and then output a test success message.

[0059] Of course, there may be a normal error between the feedback execution data and the expected execution data. As long as the gap between the feedback execution data and the expected execution data is within the normal error range, it is considered that the control and display test is successful, and then output a test success message.

[0060] In some embodiments, the device testing method further includes: recording and saving the TCS device test results, and displaying the TCS device test results on the operation interface.

[0061] It can be understood that after obtaining the TCS device test results, the TCS device test results can be recorded and saved. For example, the TCS device test results can be sent to the database through the test manager.

[0062] The control and display test platform can also be connected to a display. The operation interface can be displayed on the display, and the TCS device test results can be displayed on the operation interface.

[0063] In some embodiments, the device testing method further includes: if the acquisition of the test script file fails, or the execution of the test script file fails, then outputting a test failure message and displaying the test failure message on the operation interface.

[0064] It can be understood that in the above step 110, the acquisition of the test script file may fail. If the acquisition of the test script file fails, then outputting a test failure message and interrupting the subsequent execution steps. The test failure message can be used as the TCS device test result.

[0065] In the above step 120, the execution of the test script file may also fail. If the execution of the test script file fails, then also outputting a test failure message and interrupting the subsequent execution steps. The test failure message can be used as the TCS device test result.

[0066] The test failure message can be recorded and saved. For example, the specific failure steps, time, and reasons of the test failure message can be recorded, and the test failure message and the corresponding specific failure steps, time, and reasons can also be displayed on the operation interface.

[0067] In some embodiments, the device testing method further includes: if the sending of the control and display command data fails, or the reception of the feedback execution data fails, then outputting a test failure message and displaying the test failure message on the operation interface.

[0068] It can be understood that in the above step 130, the sending of the control and display command data to the TCS device may fail. If the sending of the control and display command data fails, then outputting a test failure message and interrupting the subsequent execution steps. The test failure message can be used as the TCS device test result.

[0069] In the above step 140, the reception of the feedback execution data may also fail. For example, the TCS device does not send the feedback execution data to the control and display test platform. If the reception of the feedback execution data fails, then outputting a test failure message and interrupting the subsequent execution steps. The test failure message can be used as the TCS device test result.

[0070] The test failure information can be recorded and saved. For example, the specific failure steps, time, and reasons of the test failure information can be recorded, and the test failure information, as well as the corresponding specific failure steps, time, and reasons, can also be displayed on the running interface.
