The locomotive operation monitoring device information refers to the locomotive operation status information including locomotive number, locomotive type, locomotive operation status, speed, kilometer mark, time and other information. It should be noted that the locomotive operation monitoring device information is not the information of the locomotive signal monitoring device (JMS host).

In this embodiment, the parallel port information output of the simulated locomotive signal host is realized by LTV-247 and 74HC139PW decoding chips, and the serial port information output of the simulated locomotive signal host is completed by NSIP83086-DSWTR; the parallel port information includes light color information, speed level information, insulation node information, etc., and the serial port information includes locomotive signal remote related information. The information is output to the JMS host through the interface isolation module to test its function.

[0038] Interface isolation module: command control is performed through the locomotive signal host output module, and then the NSI1312D chip is used to directly isolate the JMS test device from the JMS host under test, ensuring that a failure in the test device will not cause abnormal operation of the device under test.

[0039] The signal input end of the TAX box information output module is connected to the third signal output end of the core processing module, and command control is performed through the core processing module; in this embodiment, the TAX box information output module adopts the NSIP83086-DSWTR chip to output TAX box information; at the same time, the signal output end of the TAX box information output module is connected to the third signal input end of the JMS host, and the core processing module can output the TAX box information (actually the locomotive operation monitoring device information) in real time, and send it to the JMS host by outputting the TAX box information, including locomotive number, locomotive type, locomotive operation status, speed, kilometer mark, time and other information.
