红外线防盗报警器系统设计

湖南理工学院毕业设计（论文）AbstractWith the continuous development and progress of society,people have more and moreattention to security issues on the property,now life also have a wide range of security products,some can protect the personal safety of others can protect the property safety,the design isaccording to the show set a microcontroller based intelligent residential burglar alarm,can thehouse property safety.Intelligent anti-theft alarm system of this design is mainly realized in the house when noone can set don't open,the house is in a monitoring state,when a sensor detects when someoneenters the thief into the house,the control system will control the alarm device for alarm.Through searching related literature summary ideas in the design process design,the design isdivided into two parts:hardware design and software design in the design:in hardware design ismainly based on the design task of the hardware diagram of the whole system design,hardwarecircuit diagram is designed according to the diagram of each module,including the MCU modulecircuit,pyroelectric sensor module circuit,alarm circuit and key module setting module circuitetc..The system mainly uses the C language technology to design and debug the software controlprogram.After the test of hardware and software,the physical circuit board is designed.This design has the important use value in the life,and the design cost is low,the volume issmall,may use flexibly.Key words:single chip microcomputer;pyroelectric infrared sensor;alarm circuit;intelligentanti-theft
