1. The building safety monitoring system based on the wireless sensor network is characterized by comprising a building safety monitoring data acquisition module, a building safety monitoring data transmission module and a building safety monitoring center;

  • the building safety monitoring data acquisition module acquires data through a wireless sensor network, and comprises data acquisition nodes and cluster head nodes, wherein the data acquisition nodes are arranged at a detected part and used for acquiring building safety monitoring data of a monitoring area;

    the cluster head nodes are used for collecting building safety monitoring data collected by the data collection nodes and performing data fusion processing and data compression processing on the building safety monitoring data;

    the building safety monitoring data transmission module is used for transmitting the building safety monitoring data of the cluster head nodes to the base station;

    the building safety monitoring center is used for receiving building safety monitoring data of the base station through the mobile communication network, analyzing and processing the building safety monitoring data and outputting a monitoring result;

    the data acquisition node acquires the building safety monitoring data of the monitoring area according to a set data acquisition strategy;

    the cluster head node is set to be in an active state all the time in the optional period, the data acquisition node enters the active state with random probability before the building safety monitoring data is acquired each time, and a calculation formula for defining the random probability is as follows;
