Design Of Doors And Windows Linkage System Based On PIC And CC2420

The Smart home system is the use of advanced computers and communicationtechnologies, a variety of devices in the famliy(such as lighting systems,environmental control, security systems, networks appliances)connected via a homenetwork with a unified intelligent control. This topic is the CC2420chip andPIC18F4620module, ZigBee technology uses C51RF-3-JX development board smarthome system-based experimental research, the main achievement of the function: by aterminal equipment put on the lock core, the receiving module can receive the signaland indicate the electrical appliances to close the window, and then the indicator lightflashes. When we come back home and open the door, intelligent control will be overand we can open and close our windows manually.In this design, the central control in intelligent home system, door locks,information gathering and lock the window to control the three modules of thehardware design, to determine the micro-processing chip and the RF chip peripheralconnections on the power supply circuit, interface circuit, signal converter circuit andlight circuit to do the design and analysis. Through two chips the initial setup and theprogram flow chart of the microprocessor control of the RF chip and radiofrequency(RF) chip network structures and networking process, the final test interfacedata reflects the data transmission and reception.This study uses a ZigBee, this is a short-range, low-rate wireless network, homewireless router network lock control and window switch control connected together,making it in the lock at the same time automatically lock each home windows, homesecurity index. At the same time, the overall design of the system can be based on theactual application of the actual application of the same modified and applied to otherfamilies in the field of intelligent control, for example, by detecting the heatingtemperature control humidifier steam displacement of intelligent systems.
