Research And Implementation Of Embedded System In Intelligent Household

rapid development of computer technology and network technology make the ind-ustrial fields and all areas of life quickly into informatization automation and intelligent, which also gives household intelligent the very big development space.Presently, the in-telligent household has broad market needs, based on which it designed and developed an intelligent household system which is with embedded ARM system structure for dev-elopment platform and with linux for operating system.This design mainly achieved wireless connection between the embedded ARM ma-in controller and the information home appliances as well as wireless transceiver data a-nd control for household appliances, and based on which realized remote monitoring an-d control for intelligent household system through the cable connection between the A-RM main controller and the remote computer.For the family network between the controller and information appliance, By com-paring the several wireless transmission technology finally we choice the bluetooth as t-he wireless networking technology,and used the bluetooth adapter based on BlueCore4-Flash series bluetooth chips that is produced by British CSR company to realize the co-nnection between the controller and appliance. Here the bluetooth adapter is equivalent to a serial line and simulated a9needle RS232serial, and played the cable replacement role, which can avoided the cable wiring that will bring us heavy workload. And becau-se bluetooth support AT instruction set, so for the bluetooth adapter that is connected e-ach other we can realize the controller to the status of the information home appliances by sending AT commands to receive and dispatch data.For remote control of the system, first of all, Web server was successfully transplanted to the ARM development board which is main controller, then it writed static parts of the monitoring system website by using HTML--ypertext markup language and writed dynamic parts with CGI namely general gateway interface language, operation results of the CGI programs were send to the client browser in the form of the HTML pages, which achieved interaction between the system and users. In the design, remote monitoring system mainly realized the indoor temperature monitoring through displaying measured value of the temperature sensor, showing and regulating operation state of information home appliances such as air conditioning, refrigerator.
