The Design of Community Alarm System
Abstract: The thesis is based on MCU burglar alarm system, using infrared alarm, by infrared sensor to monitor the deployment area, when the detected intrusion signal to drive its speaker alarm. At the same time, transmitting signals from the machine, the host receives from the coded signal machine, the processing circuit, output control signal, trigger buzzer alarm, while USB connection to communicate with the PC machine, PC machine intrusion location. This design adopts the idea of modular design make the design more flexibility, high reliability, simple operation, good economy.
