A Research of the Positioning System for Rail Transit Based on Wireless Sensor Networks

Abstract:

Article Preview

The paper provides a method to establish a system for monitoring the arrival time of trains or subway trains, and their real-time positions and speeds during runtime. The system consists of wireless sensor nodes along the tracks and in the gateways at stations, which are connected to a central control room. The monitoring principle is the following: (1) when a train or subway train is entering the detection area, the related nodes will work and monitor data including the real-time positions and speeds; (2) when all data are obtained, the nodes will process the data and transfer the data to the gateways; (3) the gateways will further process the data and transfer the data to the central control room. Then, the central control room will provide the information of the arrival time, real-time positions and speeds of trains or subway trains to each station. Apparently, this system and method will provide a base for the safely automatic operation of trains or subway trains.
