Abstract

The disclosed system includes network central station in locomotive, and network junction station in each carriage. Both of the said network central station and network junction station is as front end, back end, data acquisition and execution unit and power section of equipment including digital signal processor and free space optical communication portion (FSO) of the forwarding and device control center. FSO includes optical transceivers A and B. In charge of carrying out continuous monitoring in real time for state of locomotive and carriages, data acquisition part in the data acquisition and execution unit includes wind pressure sensor, thermal axis sensor, bearing sensor, derailment detector, digital camera etc. The execution unit controls a banking locomotive to act operations accordant with main locomotive. The execution unit for carriage controls braking and releasing electropneumatic valve.

Description

(1) Technical field [0001] The invention relates to a free space optical communication (FSO) technology-based, additional Bluetooth (Bluetooth) equipment, wireless broadband USB (WUSB) equipment, IEEE802.xx equipment, infrared communication (IrDA) equipment, Wi-Fi Mesh ad hoc Network equipment, any one of the GPRS communication module as a backup train on-board wireless ad hoc network communication and train status real-time monitoring system. The present invention is mainly applied to a network communication system that automatically establishes a wireless link between two adjacent car bodies of a train with multiple locomotives on the railway, through which the network system can conveniently realize train traction, braking and Mitigation control and real-time monitoring of the whole train status, etc. (2) Background technology [0002] Known railway vehicle braking system is to rely on locomotive stewards to control the brakes, and the braking system of each train vehicl...
