Description

Technical Field

[0001] The present invention relates to rail transit technology, and more particularly to a method, device, computer storage medium and terminal for equipment testing. Background Art

[0002] The train control center equipment, referred to as the train control center (TCC) equipment, is the core ground equipment of the train control system. It comprehensively analyzes the line speed limit information, track section status and signal interlocking route information, etc., obtains the train driving permit, and then transmits it to the onboard subsystem through the train-to-ground communication channel to ensure the safety of all trains under its jurisdiction. The normal operation control of the TCC equipment is inseparable from the data interaction with the ground equipment connected to it (the ground equipment connected to the TCC equipment is referred to as the ground equipment in this article). While receiving the data from the ground equipment, it makes logical calculations based on the received data and issues instructions to one or more related ground equipment to complete the corresponding operations. Therefore, the interface data between the TCC equipment and the ground equipment has become the key to ensuring the safe and efficient operation of high-speed railways.

[0003] When the TCC device interacts with the ground equipment, the interface data of the TCC device is the byte data generated by the train control lower computer software through logical operations according to different train operation scenarios; because the lower computer software of the TCC device has a large software change span due to demand, for the interface data of the TCC device after the lower computer software is changed, the test and verification personnel cannot intuitively identify whether the change of the interface data is within the allowable range, whether it complies with the correctness of the change, and whether it complies with the fault-oriented safety principle. The relevant technology is generally judged and identified manually, generally by checking the terminal data or manually calculating after consulting the protocol specifications. Because there are many test modules involved, many ground devices connected to the TCC, and different interface protocols corresponding to different ground devices, it causes a large amount of calculation, a long test cycle, and is prone to problems such as missed tests and wrong tests.
