Abstract: Due to energy and bandwidth constraints，data collection，processing and transmission of wireless sensor network deployed in railway roadbed monitoring area，are required to be low energy consumption, high efficiency and high reliability. This paper puts forward the wireless sensor network clumping deployment strategy for intelligent monitoring, which would deploy data collection node as much as possible, and divide network to cluster as a single unit according to the number of node types, environmental characteristic. Processed the collection data using adaptive weighted fusion processing technology, which helps reduce data redundancy, improve data accuracy and collection efficiency. Simulation performance analysis shows that this method can greatly improve the data transmission efficiency, reduce the network energy consumption and prolong the network life cycle.
