Problems solved by technology

[0004] Although there are special locomotive status monitoring and data recording devices, it is impossible to directly adjust the online parameters of the locomotive
It is composed of a data acquisition module, a data transmission module and a data monitoring and recording module. It belongs to the redevelopment of the locomotive control device, and the relevant signals of the locomotive need to be re-wired. For customers, maintenance and costs are greatly increased.
In addition, some key variables of locomotive control cannot be obtained, and it is still difficult to find some key faults
Moreover, due to the harsh operating conditions of the electric locomotive, parameter configuration needs to be carried out under different working conditions of the locomotive, which is quite inconvenient for adjusting the PI parameters of the locomotive; in the past, the PI parameters were adjusted by using an oscilloscope to observe the adjustment effect and modify the locomotive control program. PI parameter value, which means that the control program needs to be modified for each change, which greatly reduces the reliability of the locomotive control device, and the parameter adjustment cycle is longer
[0005] At the same time, when the locomotive is running online, it is basically not feasible to carry multiple oscilloscopes or use data collection to observe the locomotive running status signals on the train, although some locomotive status signals and Fault entries, but because these information can only be transmitted once every 64ms, the real-time performance of the data information is poor, and it cannot accurately reflect and capture the transient hidden faults of the locomotive
At present, although some locomotives are controlled by microcomputer systems and have some fault record information, their storage space is limited. When a fault occurs, it can only record the status of 2 seconds before and after the fault. Therefore, the amount and length of recorded data are limited and cannot fully reflect the locomotive. status information for
