Abstract

The invention relates to the field of train operation monitoring systems, in particular to a train multi-way operation data switching storage device of a monitoring record plug-in. The device comprises a selector switch, an FPGA chip and a data storage chip, wherein the selector switch is connected with the FPGA chip and is used for switching data addresses of multiple kinds of train multi-way operation data and sending a data address switching signal to the FPGA chip; the FPGA chip is connected with the data storage chip and writes train multi-way operation data into a corresponding data address of the data storage chip according to the received data address switching signal of the selector switch; and the data storage chip is used for storing the train multi-path operation data of the monitoring record plug-in transmitted by the FPGA chip. According to the invention, switching is carried out through the externally configured panel switch, logic control of the FPGA chip is changed, write-in of various different train route data is realized, the time for replacing storage data is saved, and the hardware space utilization rate is improved.

Description

technical field [0001] The invention relates to the field of train operation monitoring systems, and more specifically, relates to a monitoring and recording plug-in device for switching and storing train multi-channel operation data. Background technique [0002] The LKJ2000 train operation monitoring device is an important guarantee for the safe operation of railway locomotives, and the monitoring record plug-in is the core of the LKJ2000 train operation monitoring device. [0003] With the opening of new lines of various railway companies and the change of LKJ data transfer organization, users have put forward new requirements for the storage and switching of on-board basic data of the LKJ host plug-in during operation of different transfer routes. [0004] On the one hand, the existing monitoring and recording plug-in can only write and call the data of one running crossing at a time. When the train needs to run on multiple lines, it needs to reload the LKJ data every ti...
