The domestic molding devices for monitoring the heating network compensator leakage are almost blank.To solve this problem

a new method of early warning and monitoring for heating network compensator was proposed

based on multiple-sensor direct and indirect cooperative working.Moreover

the early warning monitoring system for heating network compensator leakage was designed

which applies the temperature

flow

pressure and conductivity sensors and employs the intelligent processor and 4 G wireless sensor network technology.By using the remote data monitoring platform

the variations of break-variable

gradient and differential value of the real-time operating parameters are judged

thus the specific location of the leakage can be effectively identified.The simulation test and actual engineering application show that

the monitoring device for heating network compensator leakage can replace the conventional manual inspection methods and timely find out tiny leakage in the heating network compensator

which has an important meaning to promote the heating network optimization operation and reconstruction engineering.The research can provide data basis for stable operation and information management of heating network.
