【Abstract】In the rapid development of the high-speed rail economy，operational safety is an extremely important prerequisite.Without good safety and security，the construction of high-speed rail will be impossible.Based on the complex terrain and climatic characteristics of Chongqing area，this article starts with the external factors that may cause safety hazards in high-speed railways such as line infrastructure，natural environments and disasters，and combines embedded technology and 4G communication technologies with Chongqing High Speed Rail based on ZigBee wireless sensor networks.The research and exploration of the external environmental safety monitoring system has been carried out to compensate for the defects of poor flexibility，complicated wiring，limited monitoring range，and high construction cost of existing environmental monitoring systems.It is important for reducing the risk index of high-speed railways in Chongqing and improving the safe operation capability.The practical significance.

【Key words】High-speed railway；Safety monitoring；ZigBee；sensor network
