Title: TRAIN OPERATION MONITORING SYSTEM
Abstract:
An expansion unit used in a train operation monitoring system, comprising: a shunting interface pluggable unit for collecting a flat shunting signal; a digital input pluggable unit for collecting signals such as whistling; a digital-to-analog conversion pluggable unit for collecting a speed signal transmitted by a speed sensor and calculating the speed, and outputting a signal to drive a double needle gauge to display the real-time speed and speed limit; a satellite positioning pluggable unit for collecting satellite positioning information etc.; a WLAN pluggable unit for realizing wireless data reloading etc.; a level conversion pluggable unit for converting one-path or multiple-path running condition signals of the locomotive into contact signals for collection by the host unit; an Ethernet converter for providing Ethernet communication connection for large-volume data transmission; and a power supply pluggable unit for converting an external power supply to a power supply suitable for use by other pluggable units inside the expansion unit. A peripheral expansion box of the train operation monitoring system of an LKJ2000 train is integrated by means of an expansion unit such that the train operation monitoring system is minimized, having advantages such as facilitating expansion.
