"(the trigger information includes the track number, so the detection software can be positioned to a certain LED display screen), after all the vehicle-mounted annunciators are electrified to work, heartbeat packets are required to be sent to the server at regular time, the working state of TCP connection is ensured, meanwhile, the automatic test software platform can dynamically establish a mapping table of the equipment number and the IP address, and the software can rapidly position the IP address through the equipment number and send instruction data. And the vehicle-mounted signal machine receiving the communication command sends the output color lamp and the uplink and downlink data of the cab signal system in one second period. If the signal machine is not on-line, the software interface prompts fault information and sends a prompt message to the LED screen to display that the locomotive signal machine is not on-line and the equipment state is required to be checked.
Step three, in warehousing detection: after the AB plate switching device is electrified and is on line, heartbeat packets can be sent at regular time, and after the automatic detection platform software reads heartbeat data, the automatic detection platform software determines that the equipment is on line and starts automatic testing. If the waiting time is overtime, the LED display screen can display that the AB plate switching device is not on line, and the state of the equipment is required to be checked; first, the detection software will send a switch board command to the AB board switching device, which will force the a board to work after receiving the command. The output data of analysis loop current reader and locomotive semaphore can be compared to detection software, and LED display screen meeting prompt message simultaneously: "host A board output is being tested, please wait! If the color lamps are consistent with the uplink and downlink data and all the eight display lamps pass the test, the working normality of the host A board can be judged; secondly, the detection software sends a switch board instruction to the AB board switching device, and the AB board switching device forces the B board to work after receiving the instruction.
