Application of Burglar Alarm System in Uptown Based on AT89C2051
Abstract : AT89C2051 is powerful programmed microship,the hardware principle and software realization of gyard against theft and alarm system based on AT89C2051 are introduce.
Key words : Microchip Guard against theft and alarm syetem AT89C2051
Many person have a habit that when going to study, working for a long time They will be home anti-theft lock insurance, prevent thieves entanglements room,but even the ordinary anti-theft entanglements will be sure for skiing, the theft have rich experience of habitual is also very easy e in, they take a little time to burst in. So somebody puts forward on the door with a concealed lock control switch,it can work after the owner leave out . If the master will closed concealed system in three minutes, then system should stop work. But when there are thieves breaking to steal, and couldn't find this secluded alarm system to close it,the system will automatically alarm in three minutes.
way to realizated system
design priniples
Such as figure 1 showes, using a microcontroller AT89C2051 as a CPU, it will realize intelligent system is established by an defend switch k1, the door switch k2(often shut), microcontroller AT89C2051, an 5 v Super-mini relays (SSR), 7805 voltage regulations, an addition can report to alarm, it will enter semaphore to keep long range to link, and carry out long range supervision.
against theft the hardware of system
The AT89C2051 is a programmable EPROM Microchip of high performance by 53 bytes knot, Compatible with industry standards MCS51 instruction group and pins, the pany produces of the A
T89C2051 is a kind of microcontroller with strong function, it provided a vivid altitude useful solution to a lo
