The node utilizes the temperature sensor and a one-chip microcomputer to realize temperature detection and control for the environment in a house and is characterized by being simple in structure, low in cost, and easy for popularization.

Description

Intelligent domestic system temperature control node based on ZigBee

Technical field

The utility model belongs to Smart Home control technology field, relate to a kind of based on the control of the temperature in the intelligent domestic system of ZigBee node, adopt specifically 8 8-digit microcontrollers and temperature sensor to realize temperature detection and control in the home environment, in order to create a comfortable home environment.

Background technology

High speed development along with technology such as computing machine, electronics and networks, and people are to the pursuit of quality of life and the change of residential conception, people more and more pursue the intellectuality of the trifling matters of everyday life, wish can both insert intelligence program in daily life staying idle at home, thereby enjoy simple life operation.Thereby the life staying idle at home environment of intelligence becomes following a kind of development trend.It not only can provide exquisite home room to the user, and can provide safer, comfortable living environment to the household.The development of electronic industry also makes intelligent domestic system turn to gradually embedded system field take embedded home gateway as core take PC as control center by when beginning.

The development of ZigBee technology makes the intelligent domestic system wireless penetration develop into a kind of trend.This mainly because wireless network can provide greater flexibility, has saved the energy and the expense that connect up in the intelligent domestic system, provides very easily approach for common household is upgraded to intelligent domestic system.Safe, low-cost, the low-power consumption of ZigBee technology, closely waiting characteristics all to meet very much the demand of intelligent home network, is a developing direction of following Smart Home so ZigBee technology and intelligent domestic system are merged.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of with low cost, simple in structure, being applied to based on the control of the temperature in the intelligent domestic system of ZigBee node of being easy to promote is provided, thereby realizes temperature detection and control in the home environment.

The technical scheme that the utility model adopts is: a kind of intelligent domestic system temperature control node based on ZigBee, have controller, and also comprise the DS18B20 temperature sensor that links to each other with controller; The ZigBee wireless communication module that links to each other with controller; The temperature control modules that links to each other with controller.

Described DS18B20 temperature sensor links to each other with the I/O interface of controller, is used for the detection and numeral output of home environment temperature.
