It should be noted that the execution subject of the method may be a computer device.
Optionally, the rail transit signal equipment (such as a power supply device, a turnout device, an axle counting device and an on-board device) is electrically tested by adopting a testing tool, so that the electrical qualification of the rail transit signal equipment from hardware development to a production testing link is ensured.
Based on factors such as the running environment and the realization efficiency of the test tool, a Java language is adopted to develop the test tool, and a design test tool framework is constructed by combining the socket cross-platform technical characteristics; the UI interface of the test tool is developed in Java-SE language by adopting a Swing framework, and the UI interface is developed by compiling codes, defining a proprietary protocol format and the like; the test tool and the board card to be tested are subjected to data interaction in a question-and-answer mode by adopting a TCP protocol, and meanwhile, the test tool has a friendly interactive interface and interactive logic, is simple and easy to use and realizes cross-platform use.
The test tool is connected with a board card to be tested in rail transit signal equipment through reliable TCP communication, a C/S (client/server) interaction mode is adopted, and development is carried out by combining an object-oriented programming idea with a UML (unified modeling language); the operation habits of testers are fully considered, and an easily-operated guiding type user interface UI is adopted.
