Environment Monitoring system of Rail Transit based on ZigBee Protocol

Abstract：With the high development of subway and high-speed railway in our country, people gradually begin to pay attention to the construction of rail transit communication project, not only for the purpose of convenience to life, but also for the problem of travel safety. Rail transit safety is the most important problem, which involves many aspects. This paper mainly discusses the impact of environmental factors on rail transit. Monitoring the environmental factors of rail transit is to ensure rail transit is a kind of preventive method for the potential danger of track, which has a certain significance of research. This paper mainly studies the application of ZigBee protocol in rail transit, and designs a system based on ZigBee protocol to monitor the environment of rail transit, which can be monitored in real time. A series of factors affecting the track such as temperature, humidity, vibration and so on are displayed by the signal centralized monitoring system (PC of the environmental monitoring system of rail transit). This design uses CC2530 MCU, which is a special communication system solution for IEEE 802.15.4 and ZigBee protocol produced in Texas. This paper mainly describes how to configure the sensor and make up the wireless sensor network by CC2530 chip. A small network composed of four ZigBee modules and how to design a signal centralized monitoring system to be connected with the central computer in the ZigBee rail transit system to read the data collected by the node and display it on the signal centralized monitoring system.
