Abstract

The invention provides an expansion unit used in a train operation monitoring system, comprising: a shunting interface plug-in for collecting level adjustment signals; a digital input plug-in for collecting signals such as whistles; a digital-to-analog conversion plug-in for Collect the speed signal sent by the speed sensor, calculate the speed according to the speed-related information sent by the host unit, and output the signal to drive the two-hand meter to display the real speed and speed limit; the satellite positioning plug-in is used to collect satellite positioning information, and the collected The information is sent to the host unit; the WLAN plug-in is used to realize wireless data replacement, and replace the basic data of the host through WLAN; the level conversion plug-in is used to convert one or more locomotive working condition signals into contact signals for supply The host unit collects; the Ethernet switch is used to provide an Ethernet communication connection for large data transmission; and the power plug-in is used to convert the external power supply into a power supply suitable for other plug-ins inside the expansion 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...
