基于单片机的红外防盗报警系统设计
Infrared burglar alarm design controls which based
on the monolithicintegrated circuit
Abstract ： Along with society's unceasing progress and science and
technology,economical unceasing development, the people living standard obtainsthe
very big enhancement, to private property protection consciousnessin unceasing
enhancement, thus set the new request to the securitymeasure. This design is for
satisfy the family type electron securitysystem which the modern housing security
needs to design.
At present in the market condition equips mainly has the pressure totouch the
hair style burglar alarm, the switch electron burglar alarmand the pressure shields
light the hair style burglar alarmand so on each kind of alarm apparatus, but these
kind of quite commonalarm apparatuses all have some shortcomings. installm the
antijamming ability strong, thesensitivity high, safe was reliable. This kind of security
installmenthiding, was not easily discovered by the bandits and
thieves.Simultaneously its signal after monolithic integrated circuit systemprocessing
the convenience and P the C machine correspondence, isadvantageous for the
multiuser unification management.
This design designs two parts including the hardware and software. Thehardware
partially including the monolithic integrated circuit controlcircuit, infrared pokes head
in the electric circuit, t the overall system is works under the systemsoftware control.
The system program may divide into following severalmodules: The data acquisition,
the keyboard control, reports to thepolice with the demonstration small steelyard
function.
Key Words: AT89S51 monolithic integrated circuit, infrared sensor,data
acquisition, alarm circuit
