Problems solved by technology

The heat meter method mainly uses a mechanical heat meter or an ultrasonic heat meter plus a temperature control valve, which is widely used in Tianjin. This method has been tested for a long time and is relatively stable, but it has the following disadvantages: 1. Water quality problems, If the water quality is poor, it is easy to cause blockage of the mechanical heat meter; the measureme

Embodiment Construction

[0034] like figure 1 As shown, the system control mode of the present invention can set up a management and control group in the whole community or heating area as a whole, that is, a heating control center is set up, and the heating control center is equipped with computers, charging management modules, data sending and receiving devices, etc.; The control center directly controls the building distribution devices of each heating building, and the communication between each control center and the building distribution devices is transmitted in a wireless or wired manner. The data calculates the heat apportionment value of each user; it controls the on-off controller of each floor or heating unit, and the communication between the building apportionment device and the on-off controller is transmitted in a wired manner, and uses power carrier communication technology to transfer Power supply and communication are realized through a power line, and the on-off controller is direc...

Abstract

The invention discloses a heat metering system, which comprises a metering control unit composed of a total heat meter of a building, a building allocation device and an on/off controller, and a user terminal unit composed of an on/off control valve, a flow adjusting valve, a room temperature controller, a water inlet temperature sensor, a water return temperature sensor and a thermoreceptor. In addition, a heat metering allocation method of the heat metering system is also provided by the invention; the room temperature controller detects indoor temperature in real time; the on/off controller transmits a start command to the on/off control valve of the user to supply heat when the temperature is lower than the temperature set by the user; and the on/off controller transmits a close command to the on/off control valve of the user to stop heat supply when the temperature is higher than the temperature set by the user. Hierarchical control and module design are carried out by the system disclosed by the invention; the quantity and the structure of each sub-system can be flexibly adjusted according to the engineering actual situation and safely protected layer by layer, and basic life needs and effective heat metering control of the user can be ensured.

Description

technical field [0001] The invention relates to a building heat metering system with real-time heat apportionment function. Background technique [0002] With the continuous advancement of my country's urbanization process and the continuous increase of urban residential area, central heating has become the development trend of my country's heating field. At the same time, with the continuous improvement of people's requirements for material living standards, many central regions that used to have no central heating have begun to use heating facilities more and more widely. Because the traditional heating metering method only measures and charges by area, it cannot reflect the fairness and rationality of the charges, nor can it mobilize the user's awareness of heating and energy saving, wasting a lot of energy, which violates the social concept of environmental protection and sustainable development . [0003] At present, the heat metering methods tried in many areas inclu...
