Monitoring method of high-speed train operating environment

Abstract

The present invention discloses a high speed train operation environment monitoring method which can solve the existing problem that a destination node of a wireless sensor network is limited to process and analyze the sensor data. The method comprises the steps of using a sensor node of the wireless sensor network to carry out the data coding on the high speed train ground operation environment monitoring data according to the node information of the sensor node and the obtained information of the high speed train ground operation environment monitoring data to obtain the coded high speed train ground operation environment monitoring data; using the sensor node to send the coded high speed train ground operation environment monitoring data to the destination node of the wireless sensor network in a one-hop or multi-hop manner.

Description

technical field [0001] The invention relates to the technical field of monitoring the operating environment of high-speed trains, in particular to a method for monitoring the operating environment of high-speed trains. Background technique [0002] The wireless sensor network is composed of sensor nodes with perception, computing and communication capabilities. All nodes form a one-to-many or many-to-one communication network through self-organization, and send the collected sensor data through one or more hops. to the destination node. Wireless sensor networks have broad application prospects in the field of high-speed railway operation environment monitoring. [0003] However, the existing sensor data transmitted through the wireless sensor network does not include the latitude and altitude information of the sensor node and the transmission distance information when the sensor data is transmitted to the current sensor node, so the destination node of the wireless sensor ...
