Description

Technical Field

[0001] The present invention belongs to the technical field of smart home, and in particular relates to a method and a device for regulating the temperature of a heating pipe network at a central heating terminal. Background Art

[0002] Heating is an important way for residents to keep warm in winter. The standard indoor temperature for winter heating is 16℃-24℃. At present, most northern cities require that the indoor temperature for winter heating should not be lower than 18℃. The radiator central heating system should be designed for continuous heating at a heat medium temperature of 75℃-50℃ or 85℃-60℃; the water supply temperature for low-temperature hot water floor radiation heating should not be greater than 60℃. The water supply temperature for civil buildings should be 35℃-50℃. With the start of centralized heating in the north, many owners have reported that the heating temperature of their own water floor heating is not very ideal, and some families even install floor heating that has "no temperature" at all. The owners are really complaining that they have spent money but cannot get the ideal heating effect. In this way, it is necessary to effectively detect the indoor ambient temperature, but various smart home temperature detections on the market still have various problems.

[0003] For example, a distributed intelligent energy heating system and method disclosed in the authorization announcement number CN107461800A, although it enables energy enterprises to reduce personnel costs through remote management, improve energy efficiency and service quality, and reduce heating costs by more than 30% each year; residents use this system, using mobile phones, computers and other terminals to not only query energy consumption in real time, but also adjust the room temperature by themselves, and control the room temperature within the optimal standard of comfort and energy saving, achieving the dual effects of optimal body feeling and saving money, but it does not solve the existing uneven distribution of central heating heat. Now the community is centrally heated, some rooms have high room temperatures, and some rooms have low room temperatures, and the specific room temperature of the customer cannot be obtained in real time. It is impossible to achieve intelligent regulation of pipe network heating according to the terminal temperature to achieve client comfort. Some existing thermostats only realize the collection of indoor temperature, but are not accurate to the area of ​​the room. The current single room temperature and room area information cannot match. In terms of the installation of intelligent thermostats, samples are taken and measured according to the front end, middle end and end of the central heating pipe network, which not only avoids the cost pressure caused by the full deployment but also ensures the scientific nature of data collection. The temperature control modules can be flexibly networked to take into account the data of multiple rooms. To this end, we propose a method and device for regulating the heating network at the terminal of centralized heating. Summary of the invention

[0004] The object of the present invention is to provide a method and device for regulating the temperature of a heating pipe network at the terminal of a centralized heating system, so as to solve the problems raised in the above-mentioned background technology.
