On-off time area method heat metering system

Abstract

The invention is an on-off time area method heat metering system which is characterized in that an indoor temperature controller is fixedly installed in a room of a user and provided with an anti-moving device, an on-off controller has a multi-split function, the users on the same floor share a on-off controller, an EOV (electrically operated valve) is installed on a heat supplying main pipeline of the users, a building heat meter is installed the main pipeline of a building heat supplying system, an acquisition calculator is installed on the middle floor of a middle unit of a building, the system adopts a centralized power source for supplying power, wireless communication is adopted among the indoor temperature controller, the on-off controller, a repeater and the acquisition calculator, and wire communication is adopted between the building heat meter and the acquisition calculator. The system adopts the centralized power source to supply power for the system, the on-off controller is of a multi-split mode, the entire construction cost of the system is reduced greatly, simultaneously, the system can amend the quantity of heat apportioned by the on-off time area method according to the indoor temperature situation of the user, which makes charging more scientific and reasonable.

Description

technical field [0001] The invention relates to the technical field of heat supply metering, in particular to an on-off time area method heat metering system. Background technique [0002] The on-off time area method heat metering system is one of the main heat metering methods implemented in the current heat metering reform. It can not only apportion the heat consumption of the building, but also adjust and control the user's indoor temperature to achieve energy saving. At the same time, it can upload the user's indoor temperature, which provides important information for the production of thermal power enterprises. Therefore, it has been widely promoted and used in many domestic provinces and cities. However, many deficiencies in the system have been found in actual use. The first is that the cost of the system is relatively high (including the cost of the product itself, construction and installation, and supporting projects). In order to supply power to the on-off contr...

Problems solved by technology

However, many deficiencies in the system have been found in actual use. The first is that the cost of the system is relatively high (including the cost of the product itself, construction and installation, and supporting projects). In order to supply power to the on-off controller in the system, it is basically to install a power supply for each unit. In this way, not only the cost itself is increased, but also an electric energy metering device needs to be installed in each unit to measure the heat of the unit. The electric energy consumed by the metering system greatly increases the cost of the entire system; in addition, the on-off controller in the current system basically uses one for each household, corresponding to the user one by one, and the cost is also high

The second is that the heat allocation error is relatively large, especially when the user's heating system cannot meet the standard requirements, the error will be even greater, which directly affects the heat allocation and charging

According to the requirements of "Technical Conditions for On-off Time Area Method Heat Metering Device", when the user's heating system does not meet the standard requirements, the heat allocation formula given in the standard should be corrected. The current situation is that quite a few heating systems do not meet the standard requirements. At the same time, the vast majority of enterprises that produce on-off time area method heat metering systems have not corrected the calculation results, a small number of enterprises have adopted the correction of inlet and return water temperatures, and some other enterprises have provided the function of user location correction, but the effect is not good. Ideal. In addition, although the system itself can collect the user's indoor temperature, most of the room temperature controllers in the on-off time area method heat metering systems produced by various enterprises cannot be fixedly installed, and a few that can be fixedly installed do not have the anti-movement function. , the user can manually interfere with the uploaded indoor temperature data, therefore, the user's indoor temperature collected by the system cannot be used to correct the allocation results
