Train running monitoring system

Abstract

The invention provides an extension unit which is used in a train running monitoring system. The extension unit comprises a shunting interface plug-in, a digital value input plug-in, a digital-to-analogue conversion plug-in, a satellite positioning plug-in, a WLAN plug-in, a level switching plug-in, an Ethernet exchange board and a power source plug-in, wherein the shunting interface plug-in is used for collecting shunting signals; the digital value input plug-in is used for collecting signals such as whistling; the digital-to-analogue conversion plug-in is used for collecting velocity signals transmitted by a velocity sensor, calculating the velocity according to velocity-related information transmitted by a mainframe unit and outputting a signal to drive a double-pointer meter to display the actual velocity and the velocity limit; the satellite positioning plug-in is used for collecting satellite positioning information and transmitting the collected information to the mainframe unit; the WLAN plug-in is used for achieving the wireless data reloading and replacing mainframe basic data through WLAN; the level switching plug-in is used for converting one path or multiple paths of locomotive working condition signals into contact signals allowing the mainframe unit to collect; the Ethernet exchange board is used for providing Ethernet communication connection which is used for large data volume transmission; the power source plug-in is used for converting an external power source into a power source which is suitable for being used by other plugs-in inside the extension unit.

Description

technical field [0001] The invention relates to a train operation monitoring system, more specifically, relates to a train operation monitoring system adopting an integrated design of peripheral equipment. Background technique [0002] On the train, the train operation monitoring system such as the LKJ2000 train operation monitoring system currently used in mass production of domestic locomotives is the core component of train operation safety protection. LKJ2000 train operation monitoring system has continuously added peripheral boxes including digital-to-analog conversion boxes, level adjustment boxes, and function expansion boxes in the process of product application development in order to adapt to the interfaces of various equipment on the train. [0003] figure 1 It is an example configuration diagram of the LKJ2000 train operation monitoring system. Such as figure 1 As shown in , various devices are connected around the monitoring host, such as I-end and II-end scr...

AI Technical Summary

Problems solved by technology

from figure 1 The displayed structure of LKJ2000 shows that there are multiple peripheral boxes connected to the periphery of the monitoring host, and with the continuous expansion of functions, the number of connected devices may increase, resulting in problems such as scattered devices, taking up a lot of space, and inconvenient fault finding.
