Simultaneously, a flexible temperature regulation way is provided, and the regulation and control demands of the different users can be better met; and the remote real-time monitoring based on Internet is realized, real-time inquiry, regulation and control through mobile phone short messages can be realized, and the use of each user can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of building heating measurement and control, in particular to a Zigbee-based central heating control system for public buildings. Background technique [0002] Energy and environmental issues have always been the two major themes that plague the development of the world today, and have always been the strategic focus of my country's economic work. Today, serious environmental problems are caused by the massive waste of building energy. In northern my country, heating energy consumption in winter accounts for about 65% of building energy consumption. Especially in public buildings, heating management is relatively extensive, resulting in serious waste of resources. At this stage, the extensive management of the heating system and the lack of infrastructure configuration lead to the unreasonable use of heat by heat users, which is a relatively obvious and prominent energy consumption problem reflected from th...

Problems solved by technology

Moderate control depends on accurate measurement. Temperature is the main index to reflect the thermal comfort of thermal users. In recent years, predecessors have proposed many methods in the measurement of building interior temperature: Lei Chun et al. Design and Implementation of Point Temperature Acquisition System" designed a multi-point temperature acquisition system based on wireless sensor network technology, and built a wireless network based on the ZigBee protocol stack to realize data acquisition and transmission between master and slave nodes. Chen Lei et al. A public place temperature collection system based on ZigBee technology" introduced a public place temperature collection framework based on Zigbee network, but these documents only give the hardware and software implementation of Zigbee-based multi-point temperature collection framework. There are no effective measures to deal with interference factors such as environment and noise, and to improve the accuracy of temperature acquisition; Zhang Juan et al. proposed a greenhouse based on multi-sensor data detection and data fusion technology in "Greenhouse Temperature Acquisition Based on Multi-sensor Data Fusion". The ambient temperature acquisition method removes the omission error of individual sensors by introducing the distribution map method, and at the same time adopts the method of recursive estimation and fusion based on the mean value to realize the effective processing of multi-sensor data to improve the accuracy of temperature measurement. However, the ambient temperature acquisition of the greenhouse It is very different from the indoor temperature measurement of public buildings, and its use of temperature measurement is also different from various environmental interference factors. Compared with the greenhouse environment, public buildings pay more attention to the accuracy of single-point temperature measurement at each temperature measurement point

Therefore, as far as the current work is concerned, there is still a lack of effective measures to accurately collect the internal temperature of public buildings, and then implement moderate heating control, and it is difficult to meet the needs of users with different heat requirements
