Problems solved by technology

[0002] In the existing heating system, the "on-off time area method" is used to measure the user's heat sharing. This method is to control the room temperature by using the control valve to control the water intake. At the same time, the accumulated valve opening time and Based on the heating area, the heating heat consumption of the whole building is allocated, and the billing is carried out according to the allocated heat consumption. The time-area method has the following problems: 1. It is difficult for the current heating system to achieve the hydraulic balance between the heat users in the building; 2. It is common for users to increase or modify radiators without permission, resulting in the same valve opening time. , the water supply temperature is the same, but the indoor temperature is different

Embodiment Construction

[0051] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0052] The heat metering system of the present invention is as figure 1 As shown, the heat metering system includes: a heat meter 101 installed on the main heating pipe of the building, an on-off valve 102 installed on the inlet pipe of the user's heating system, and a temperature sensor installed on the outlet and inlet pipes of the user's heating system 103. A room temperature controller 104, a household heat meter 105 and a remote control center 106 installed in the room.

[0053] The heat meter 101 installed on the main heating pipeline of the building measures the sum of the heat used by all users in the building and provides it to the heat meter 105 for each household. Each user in the building is an independent horizontal series system.

[0054] The user controls the temperature in the room through the room temperature controller...

Abstract

The invention provides a heat metering method and system. The method includes the following steps that a neural network is trained; the total heat of a building is obtained; the time of valve switching on / off of all households is obtained, and water temperatures of water outlets and water inlets of heating pipelines, controlled by on-off valves, of all the households are obtained; correction factors are obtained through the trained neural network, and heat of each individual household is worked out finally. According to the heat metering method and system, the correction factors are constructed by using the neural network, so that under the existing hardware conditions, heat of the individual households is worked out more fairly and reasonable.
