Office air conditioner semi-intelligent regulating and controlling system based on wireless sensor network

Abstract

The invention discloses an office air conditioner semi-intelligent regulating and controlling system based on a wireless sensor network. The system comprises a human body information detection unit, an office environment detection unit, an operating state detection unit, a central processor, a pre-warning unit and a wireless communication module. The human body information detection unit is used for detecting the human body surface temperature and the heart rate value. The office environment detection unit is used for detecting the temperature, humidity, air pressure and air speed in an office. The operating state detection unit is used for detecting a compressor and a blowing fan in an air conditioner and the operating power of the air conditioner. According to the system, environmental parameters and human body biological signals are measured through an intelligent wearable device with various sensors, demand information of the human body on the environment is acquired accurately in real time, and the working state of the air conditioner is automatically adjusted according to the demands of the human body on the environment; and by means of the arrangement of the human body infrared sensors, the number of office workers can be counted, the central air conditioner is controlled through the central processor, the central air conditioner is adjusted to output a proper amount of air, and waste of resources is reduced.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, in particular to a semi-intelligent control system for office air-conditioning based on a wireless sensor network. Background technique [0002] Wireless sensor network is currently the most widely used and concerned subject in the world as well as the field of design, and it is also a research direction of cutting-edge hotspots with interdisciplinary and highly integrated knowledge. Sensor technology, micro-electro-mechanical systems, modern network technology and wireless communication technology have all made progress at the same time. It is independent of basic communication equipment such as base stations or mobile routers, and forms a network formed by self-organization through a specific distributed protocol. It can monitor, perceive and collect information about various environments or detection objects in the network distribution area in real time through collaboration. ...

Problems solved by technology

[0003] There are many wastes of energy in the use of air conditioners

In the absence of people, the air conditioners in many offices are still working, and there are still uneven heating and cooling of the air conditioner temperature. The temperature in some places in the room is higher, while the temperature in other places is lower. The utilization rate is not maximized at all
