Realization of heat management system based on low voltage power line carrier

In the current heating system, according to heat metering and controlling the reasonable charge is an inevitable trend. Due to the high temperature of heating pipelines, the transmission line along the pipeline is easily damaged. In order to solve this problem, this system uses voltage power transmission carrier. Metering management system in this paper is based on voltage power communication carrier, and mainly consists of flow-sensor, temperature sensor, microcontroller and PLC. This paper expounds heat metering and power line carrier-current project design principle and realization circuit using PL3106 build carrier. The new technical scheme offered a good technical base of Network Management for Thermal supply enterprises.
