[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the existing equipment test of the zone controller, the zone controller ZC is connected to the external device through several external interfaces, and exchanges information with the external device through the communication protocol between the external devices, including receiving status information and command information from the external device, and outputting control information and feedback information to the external device through logical operations. In the equipment test, the simulation software is used to simulate the information output to the ZC device by each external interface for a long time, and the functional correctness and stability of the ZC device are verified by observing the operating status of the ZC device. In addition, before performing equipment testing on the zone controller ZC, it is necessary to manually design the output information of the simulation software, usually selecting the output information of the external device in some simple application scenarios. After the test starts, the simulation software continuously sends pre-designed output information to the ZC device. The tester confirms whether the ZC device is operating normally by observing the operating status and interface output of the ZC device within the specified test time period. Since the output information of the simulation software needs to be manually designed before testing, usually only simple scenarios can be selected as device test scenarios. This means that the input data of the device test cannot cover all possible application scenarios of the device, affecting the comprehensiveness of the device test. At the same time, during the device testing process, testers are required to continuously observe the operating status and interface output of the device, which will take up more manpower and time for long-term device testing.

[0033] Figure 1 A schematic diagram of the structure of a device testing system for a city rail area controller provided by an embodiment of the present invention, such as Figure 1 As shown, an embodiment of the present invention provides a device testing system for an urban rail area controller, including a test scenario library module 101, a test data generation module 102 and a simulation software module 103, wherein:

[0034] The test scenario library module 101 is used to store and parse the acquired test scenarios, generate a target test scenario for the urban rail area controller to be tested according to preset test conditions, and send the target test scenario to the test data generation module 102. The target test scenario is used to verify the functional points of the urban rail area controller to be tested.

[0035] In an embodiment of the present invention, the main function of the test scenario library module 101 is to store and parse test scenarios that can verify the function points of the zone controller ZC. In order to ensure the accuracy and completeness of the test, the test scenario library module 101 needs to include all possible practical application scenarios as much as possible. In an embodiment of the present invention, a typical test scenario includes the following elements: the status of each device (signal, axle counter and section, etc.) on the urban rail line, the train status and external commands, etc. The test scenario library module 101 matches all test scenarios with the function points of the zone controller ZC according to the preset test conditions, thereby obtaining the target test scenario for the urban rail zone controller to be tested, so that the target test scenario and the zone controller ZC can be bidirectionally retrieved, that is, querying the test scenario corresponding to the function point of the zone controller ZC according to the function point and querying the zone controller ZC function point covered by the test scenario according to the test scenario.

[0036] The test data generation module 102 is used to convert the target test scenario into target test data, and send the target test data to the simulation software module 103 .

[0037] In the embodiment of the present invention, the main function of the test data generation module 102 is to convert the target test scenario into target test data. Since the test scenario is an abstract description of the test and cannot be directly recognized by the simulation software, the test data generation module 102 must be used to automatically translate the test scenario into test data that can be tested by the simulation software. This process does not require manual intervention, thereby improving the efficiency and accuracy of equipment testing.

[0038] The simulation software module 103 is used to test the urban rail area controller to be tested according to the target test data to obtain the test process information of the urban rail area controller to be tested.

[0039] In the embodiment of the present invention, the main function of the simulation software module 103 is to execute the test task. The simulation software module 103 simulates the external device of the zone controller ZC based on the target test data, and sends the target test data to the zone controller ZC, thereby driving the zone controller ZC to perform device testing.

[0040] An equipment testing system for an urban rail area controller provided by an embodiment of the present invention automatically generates target test data for the urban rail area controller to be tested by constructing a scenario library for testing the urban rail area controller, thereby performing equipment testing on the urban rail area controller to be tested. Compared with the prior art, the system has a wider range of test scenario coverage and a simpler test data generation method. At the same time, the system realizes real-time testing of the urban rail area controller through the automatically generated test data, thereby saving the manpower cost and time cost of long-term equipment testing.

[0041] On the basis of the above embodiment, the system further comprises: a test information analysis module, which is used to collect and analyze the test process information sent by the simulation software module to obtain the test analysis data of the urban rail area controller to be tested.

[0042] In an embodiment of the present invention, the main function of the test information analysis module is to be responsible for the collection and analysis of test process information. Through the test information analysis module, the test process information (including the internal state and output of the zone controller ZC) is collected and analyzed in real time, so that the tester can monitor the entire equipment test process through the test platform interface very intuitively and conveniently, and promptly discover and respond to faults and alarms during the test process. Preferably, in an embodiment of the present invention, the test information analysis module also supports query and analysis of historical test processes. The automatic collection and analysis of the test process information by the test information analysis module makes the test observation of the zone controller ZC easier, saving manpower and time costs.

[0043] On the basis of the above embodiment, the system further comprises: a test analysis data display module for displaying the test process information and test analysis data in real time.

[0044] On the basis of the above embodiment, the test scenario library module includes a test scenario generation unit and a test scenario matching unit, wherein:

[0045] The test scenario generating unit is used to generate various types of test scenarios according to the equipment status, train status and external commands on the urban rail line;

[0046] The test scenario matching unit is used to match the function points of the urban rail area controller to be tested with all the test scenarios in the test scenario library module, and if the bidirectional search conditions are met, the target test scenario of the urban rail area controller to be tested is obtained.

[0047] On the basis of the above embodiment, the test scenario library module further includes: a test scenario combination unit, which is used to combine multiple test scenarios to obtain a combined test scenario.

[0048] In the embodiment of the present invention, firstly, according to the test requirements, a suitable test scenario is selected from the test scenario library, and multiple test scenarios can be flexibly combined. The combined test scenario is matched with the urban rail area controller ZC to be tested by the test scenario matching unit to obtain the target test scenario; then, the test data generation module 102 reads the target test scenario and generates target test data. After the test is executed, the simulation software module 103 reads the target test data and starts the test. At the same time, the test information analysis module updates the test process information in real time and displays it on the interface of the test analysis data display module.

[0051] In an embodiment of the present invention, in order to ensure the accuracy and completeness of the test, it is necessary to obtain all possible practical application scenarios as much as possible. In one embodiment of the present invention, a typical test scenario includes the following elements: the status of each device (signal, axle counter and section, etc.) on the urban rail line, the train status and external commands, etc.; then, according to the preset test conditions, all test scenarios are matched with the function points of the zone controller ZC, so as to obtain the target test scenario for the urban rail zone controller to be tested, so that the target test scenario and the zone controller ZC can be bidirectionally retrieved, that is, the test scenario corresponding to the function point of the zone controller ZC is queried according to the function point, and the zone controller ZC function point covered by the test scenario is queried according to the test scenario.

[0052] Step 202: convert the target test scenario into target test data, and test the urban rail area controller to be tested according to the target test data to obtain test process information of the urban rail area controller to be tested.

[0053] In the embodiment of the present invention, since the test scenario is an abstract description of the test and cannot be directly recognized by the simulation software, the test scenario must be translated into test data that the simulation software can use. This process does not require human intervention, thereby improving the efficiency and accuracy of equipment testing. Then, based on the target test data, the external device of the zone controller ZC is simulated, and the target test data is sent to the zone controller ZC, thereby driving the zone controller ZC to perform equipment testing.
