District heating control system and method based on distributed sensor network

Abstract

The invention relates to a community heating control system and method based on a distributed sensing network. The community heating control system based on the distributed sensing network comprises a plurality of sensor nodes and a server. The sensor nodes are used for regularly acquiring external environment information of buildings. The server is used for conducting heating control on a community according to the environment information acquired by the sensor nodes and the solar altitude of the position of the community in the corresponding moment. According to the invention, the illumination, the temperature and the humidity of each building at the moment and the covering influence caused by shadows of adjacent buildings on the building at the moment are acquired in real time, the temperature environment of households on each floor of each building is accurately estimated, then total data are collected, and targeted and accurate heating is conducted on each household through a simulated annealing algorithm. Energy is saved to the maximum extent on the basis that the comfort of the living environment of the households is guaranteed.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a district heating control system and method based on a distributed sensor network. Background technique [0002] Western developed countries have carried out large-scale building energy conservation for more than 40 years, and their buildings are characterized by high comfort and low energy consumption. For example, France has formally stipulated the energy-saving standards for heating residential buildings in legal form since 1974. From 1984 to 1990, the energy consumption of buildings in France dropped from 42% to 45% of the total energy consumption of the society to 28%. Today, Europe has established extremely strict zero-energy residential standards, carbon dioxide emission standards and energy self-sufficiency standards, and western developed countries are far ahead in the field of building energy conservation. [0003] Compared with western developed countries, China's...

Problems solved by technology

In contrast, most cities in the north still use old-fashioned central heating and all-day heating to provide heating for residents, which can no longer meet the needs of modern cities for energy conservation and environmental protection.
