Design of Urban Rail Vehicle Sensor Network Data Transmission Simulation System

Using sensor networks technology, sensors are installed in the key parts of urban rail vehicles to collect real-time information of train status and achieve fully monitoring of trains; it is important for the safety of train. Firstly, in order to select a reasonable transmission policy and ensure real-time and reliable transmission of sensor information, this paper designs and develops sensor network data transmission simulation system for urban rail vehicles. Data transmission simulation system which is described in this article includes data collection subsystem, data storage subsystem, and data transfer subsystem. This system completely implements the function simulation of sensor networks collecting data, transferring data, and storing data in the process of train running. At the same time, considering the actual needs of the train monitoring, this paper also defines the data format and the way to code data and decode data. Secondly, based on the hardware platform described in this paper, this paper sets up an urban rail vehicle on-board distributed data processing system.
