Safety control method and system for heat supply pipe network

The invention relates to a safety control method and a system for a heat supply pipe network. The safety control method comprises the steps of S1, collecting the monitoring information of nodes in theheat supply pipe network and judging whether various types of monitoring information accord with a preset safety range or not; S2, judging whether self various types of monitoring information accordwith a preset safety range or not; and S3, carrying out safety control through a determined safety control strategy adopted by each level of node. According to the safety control method and the systemfor the heat supply pipe network, hierarchical processing of monitoring data can be carried out by using the connection characteristics of a pipe network and the attribute characteristics of node resources, hierarchical operation of security control is carried out by combining the computing power of the nodes, so that various types of nodes can have opportunities to carry out security control andcomputing processing in a c
