Metering and monitoring system and method for each door under central heating

Abstract

A metering system of individual household in centralized heating-supply device comprises remote transmitting meter unit and heating supply control valves. It is featured as erecting said control valves on various heating supply pipe, setting individual household control unit near to said control valves, transmitting information between real time centralized monitor unit and individual household control unit in two-way mode and enabling to selectively erect room temperature monitor in the room.

Description

technical field [0001] The invention relates to the field of heating metering and monitoring systems, in particular to a system and method for household metering and monitoring of central heating. Background technique [0002] At present, my country's central heating system is changing to a household metering system, and various types of household metering equipment emerge in an endless stream, such as the "heating billing control device" of my country's patent application number 02212886, the "intelligent control prepaid heating system" valve and heating prepayment control system", etc. [0003] At present, most residential buildings in China use single pipes in series to form a thermal cycle. This heating method not only has low efficiency and high energy consumption, but also is difficult to realize individual household control. For example, if a pipe on a certain floor is broken, it will affect the entire building. , Cutting off the heating in any one home will cause the...

AI Technical Summary

Problems solved by technology

[0005] 1. Poor applicability: For many old heating systems using serial lines, if household metering is to be realized, a heating control valve with billing function needs to be installed on each branch line, forming a situation of multiple meters for one household, and due to It is difficult to guarantee the accuracy and durability of metering for water quality, pipelines and other issues, which makes billing complicated, high maintenance costs, and almost impossible

[0006] 2. High cost: the heating control valve not only completes the line control function, but also completes the function of billing or measuring heating volume, which makes the structure of the control valve complex and the cost of transformation is high

[0007] 3. Poor control function: Heating users have various requirements for heating methods in different time periods and different rooms. For example, there is no need for heating during the day when there is no one at home, and only the bedroom can be heated at night, etc. These It is the current heating control device that considers less in design
