With the rapid development of China's high-speed railway, operating environment monitoring of high-speed railway becomes the key technology which has an influence on speed and safety operation. In this paper, a routing protocol and topology of wireless sensor network based on event-trigger is proposed in view of the special property where the monitoring area is banded. And the triggering mechanism scheme and the corresponding routing protocol in combination with the high performance requirements of high-speed rail are designed to extend the life cycle of network. In simulation, it is verified that the system based on event-trigger can reduce the data volume of nodes and realize the purpose of reducing the energy consumption of nodes effectively. It is significance to guide the deployment of node in the environment monitoring.
