Intellectual Control System Of Housing

With the social informationization and household intellectualization in the new century, it becomes more and more important to have a central control on multi-resources. So this paper puts forward the application and designs of the Centralized Controller Based on MCU(single-chip microcomputer)in this essay. With the introduction of the intellectual housing concept,the development of centralized controller on household appliances comes into a new stage. It can control all electrical appliances intensively in residence, hotel or office through Premises Distribution System. The controlling target can be the common switch, the opening and closing of the air condition and acoustics or even timing switch of the some other electric machines, etc.It takes MCS-51 MCU as the core design, is a multifunctional controller including a keyboard, a clock and a telecommunication interface. It consists of an upper computer and a lower computer. By using encode software, we can write a steady and reliable program code through information from the whole analysis, modeling,testing of the software engineering.The part of clock of this design, as well as the display of different time zones of regions in the world can be regulated by the key-press.The keyboard and the circuit of the clock are controlled by the MCU in the upper computer. The MCU from the lower computer is in charge of the multifunctional controlling circuit.Serial communication is realized by the connection of communication interface between two MUCs. The M UC i n control of the keyboard and clock is taken as the upper computer. After the messages typed from the keyboard are checked and disposed,it will be sent to the lower computer. The lower computer makes alogical judgment and sends out the control commands in accordance with the output results of all function circuits. It means that the multifunctional controller as the lower computer accepts the commands from the upper computer and realizes the control of electrical household appliances such as air-condition and water heaters, I i ghti ng, remote control of the temperature di stance between the outside and the i nside, self-control of the elevation of the curtain,anti-thief alarm, timing control,remote control by telephone and computer control.This thesis is based on research and analysis of the overall demand of the intelligent control system, the utilization of mature application of the MCU,and also including the requirement analysis of the system, software modeling,overall design, implementation and testing systematically by adoption of the software engineering way. All functions set by the system are realized,and succeed in realizing the applications of Intellectual control system of housing based on GPRS, the desired target of the project is reached.
