Referring to fig. 1 in conjunction with fig. 2, 3 and 4, the present application discloses an automated testing method. The test method can test the object to be tested for rail transit, and comprises the following steps:

s11, establishing an instrument program control library and a to-be-detected object program control library of rail transit, wherein the instrument program control library comprises an instrument program control unit, and the to-be-detected object program control library comprises a control program control unit;

according to the automatic test method disclosed by the application, the object to be tested can be a single electronic controller or a system (such as a traction system and a gate control system) formed by the electronic controllers according to different instruments and meters and the object to be tested, and also can be a complete machine control system formed by all sub-control systems. Referring to fig. 3, an instrument of an automatic test system includes analog and digital related tests. Fig. 3 illustrates two PXIe chassis. One PXIe case mainly completes power supply and digital quantity related test work and participates in controlling a direct current power supply (GPIB interface), a universal meter (GPIB interface), an oscilloscope (GPIB interface), a matrix switch (PXIe interface), an electronic load (GPIB interface), a programmable direct current power supply (GPIB interface), a digital source meter (PXI interface), a program-controlled switch (PXI interface) and a relay switch (PXIe interface). The other PXIe case mainly completes analog quantity testing, pulse quantity testing, communication protocol testing and temperature testing and participates in controlling a current type signal generator (GPIB interface), a voltage amplifier (BNC interface), a digital source meter (GPIB interface), a universal meter (GPIB interface), a multiplexing switch (PXIe interface), a matrix switch (PXIe interface), an MVB card (CPCI interface), an Ethernet card (PXIe interface), a CAN card (PXIe interface), an RS232/RS422 card (PXIe interface), an RS232 card (PXIe interface), a temperature acquisition card (PXIe interface) and the like.

In this step, an instrument program library for each of the instruments may be created by: s111) reading the instruction of the instrument and being familiar with all functions of the instrument and meter; s112) reading the instrument control instructions one by one; s113) programming the instrument control instructions one by one; s114) testing instrument control instructions one by one; s115) completing instrument control instructions one by one; and completing the development of instrument control instructions. After the program control design is carried out according to the steps, the instrument program control library and the corresponding instrument program control unit can be obtained. The skilled person will understand that the program-controlled library of the object to be tested and the program-controlled unit thereof can also be obtained by designing in the aforementioned manner. The program control library of the object to be tested not only includes the program control library of each object to be tested, but also includes some auxiliary program control libraries related to the test of the object to be tested, for example, the program control units in the auxiliary program control libraries include a communication board program control unit and a program control unit for numerical value conversion. The program control unit for value conversion means that the value directly extracted from the data packet is represented in a binary form, the binary form of the data and the actual physical quantity follow a certain conversion rule, and the conversion rule is usually different for different variables and different objects to be measured (such as a single electronic controller). Therefore, a numerical value-physical quantity conversion module is added in the system, a user can configure a numerical value conversion rule through the module, the output numerical value of the program control module of the object to be tested is converted into actual physical quantity, and the converted physical quantity is applied to a test criterion.

S12, splitting the test case into a plurality of test steps, wherein each instrument program control unit and each control program control unit correspond to one test step respectively;

in this step, each testing step may be a single control of the instrument by the testing system software, a single communication with the object to be tested, or other operations (delay, logic control, etc.). The test cases may be split in the order of execution of the test steps. Fig. 2 illustrates the corresponding relationship between the program control unit and the testing step, for example, the program control unit of the program control library of the instrument 1 corresponds to the testing step 1, and by analogy with the illustration in fig. 2, one testing step corresponding to each program control unit of the instrument can be obtained; each control program control unit corresponds to one test step.

And S13, calling the corresponding instrument program control unit or the corresponding control program control unit to complete the test of the object to be tested for the rail transit according to the execution sequence of the test cases and the corresponding relation between the instrument program control unit and the control program control unit and the test steps.

Referring to fig. 4 and fig. 2 in combination with fig. 1, after each test step is executed, when the next test step is executed, the corresponding instrument program control unit or control program control unit is invoked to automatically complete the test of the object to be tested for rail transit according to the execution sequence and the input required by the test step.

The skilled person will understand that the above method can achieve the following technical effects: because the instrument program control unit and the control program control unit are established, and each instrument program control unit and each control program control unit respectively correspond to one-step test step, after the test case is compiled, the test case can correspond to the corresponding instrument program control unit and the corresponding control program control unit and automatically complete the test, so that the automatic test method has high test efficiency and convenient test.
