Train operation monitoring device with novel design structure

Abstract

The invention provides a train operation monitoring device. The train operation monitoring device comprises a monitoring host, a screen display and external extension equipment; the monitoring host comprises a host board, a communication board, a locomotive signal communication board, a simulating board, an input board, an output board, a recording board and a power supply board; the host board completes mutual communication with the communication board, the locomotive signal communication board and the simulating board through an internal CAN bus; the host board accesses the input board and the output board through a parallel interface; the host board communicates with the screen display through an external CAN bus; the external extension equipment is connected with the communication board through an extension equipment CAN bus; and a recorder board is connected with the internal CAN bus and the external CAN bus simultaneously. The train operation monitoring device has the following technical advantages: in a new monitoring host structure, system internal communication and external communication buses are isolated, so that the influence on the internal part of the system by system external interference is effectively protected; meanwhile, a recording function is independently completed through bus monitoring, so that stripping of a control function and the recording function is realized.

Description

technical field [0001] The invention relates to a train operation monitoring system, in particular to a train operation monitoring system with a new structure. Background technique [0002] The train operation monitoring device (LKJ) is in line with the conditions of railway line equipment and facilities and the requirements of transportation organization in various eras, and it can play the role of ensuring safety to the greatest extent. [0003] At present, the mainstream LKJ equipped on the road is the third-generation train control equipment LKJ2000 device, which is composed of a monitoring host, a human-computer interaction unit (also known as a screen display) and other auxiliary equipment. [0004] The monitoring host is the control center of the LKJ system, including monitoring record plug-ins, ground information processing plug-ins, communication plug-ins, analog input and output plug-ins, extended communication plug-ins, digital input plug-ins, digital input and ou...
