Monitoring system and method of heat supply network

Abstract

The invention relates to a monitoring system and method of a heat supply network and can solve the problem of low utilization ratio of heat energy in the prior art. The key point of the technical scheme is as follows: the monitoring system of the heat supply network comprises an upper computer and a sub-monitoring system which comprises a controller, a primary side electric regulating valve, a primary side heat supply network circulating pump speed controller, a secondary side heat supply network circulating pump speed controller and a make-up water pump speed controller; the primary side electric regulating valve is electrically connected with the controller; the controller is electrically connected with a secondary side heat supply network circulating pump via the secondary side heat supply network circulating pump speed controller and is electrically connected with a primary side heat supply network circulating pump via the primary side heat supply network circulating pump speed controller; the make-up water pump speed controller is electrically connected with a make-up water pump; a water make-up startup circuit is connected on the make-up water pump speed controller; a sensorand a heat meter are arranged on the heat supply network and electrically connected with the controller; and the controller communicates with the upper computer via a communication network. The largest utilization ratio of the heat energy can be ensured through various control modes.

Description

technical field [0001] The invention relates to a heating network monitoring system and method, in particular to a system that can actively adjust the primary side flow and secondary side flow of the heating pipeline according to the operating status of different heating networks, and ensure the maximum utilization of heat energy through various control methods High-efficiency heating network monitoring system and method. Background technique [0002] China is a country that consumes a lot of energy, its energy utilization rate is very low, and its energy reserves are obviously insufficient. Most areas in northern my country have long winters. In order to ensure the normal heating of residents, the corresponding heating period is relatively long. Some areas need heating for more than half of the year. The heating industry has become an industry that consumes a lot of energy. In this way, under the premise of ensuring the normal heating of residents, how to respond to the re...
