The Design Of Intelligent Home Controlling System Based On Zigbee

With rising living conditions and technological advances,Smart Home is no longer unfamiliar to us,it means people have high requirements for their living condition.The inland Smart Home is famous for embedding Smart APPliance into families,but fitting up the whole Smart Home depending on house type before rough house fitting is blank.This design mainly directs to house type A of Dalian a certain district,performs full analysis of requirement and Smart Home Design.The design aimed to realize an overall solution with low cost,good expandability and satisfied with the owner's request.The solution can display temperature and humidity,investigate hazardous gas,adjust light,Infrared alarm,transmit to the owner's mobile app in time.This design is mainly aimed at selection of the indoors environment networking modes,each terminal module and processor's hardware and software development.First of all,this text introduces the current situation of domestic and foreign Smart Home,by comparing the advantages and disadvantages of several wireless transmissions,I choose the Zigbee technology for this design,it overcomes the big work quantity and high cost of cable output,it also has the characteristic of close range and low power,to be popular at present.On the hardware side,depending on analyzing own requirement,the resident decides four most concerned control and measuring content,according to their choices,this text sets up humiture terminal,gas detection terminal,light control terminal and infrared detection terminal.Choosing the sensors detection data of four node and write down the position where layout the sensor node.Choosing CC2530 chip from TI company as the coordinator of Zigbee to set up the indoor wireless communication network.On the software side,choosing IAR development software from TI Company,the powerful Z-stack provide the convenience of sustainable development of Smart Home development.Writing a protocol program of Embedded gateway,choosing the mobile phone receiving date method which is popular at present for upper computer,and synchronize the indoor data to the client's phones' APP.In the end,finish the debug test,make the summary of the design and consider the expectation to improve and optimize of the design.
