用C51单片机设计报警接收装置

Use C51 MCU to design the Receiving System Giving an Alarm

该设计为一种报警接收装置。采用性能稳定、价格低廉的C51单片机为核心部件,接收前端如主动红外、被动红外、门磁、煤气泄漏等探测器的报警信号,通过蜂鸣器、LED数码管和指示灯等提供声光报警输出,同时设置布防、撤防和清除按钮便于操作。是一种经济、适用的安全防范报警接收装置。该设计电路简单。程序用汇编语言编写,结构合理。具有扩充数码键盘、报警联动输出、与上位机通讯等功能。

Design is one kind of the receiving system giving an alarm. Adopt the cheap C51 of function price stabilization, monolithic machine to be a core component, the alarm signal receiving fore-end if initiative is infrared, passivity is infrared, probes such as door magnetism, gas leak, exports, interposes at the same time the easy to compose in reply reset button operation organizing a defence, withdrawing from a defended position by the fact that the buzzer phone, LED numerical code and guiding lights etc. provide acousto-optic warning. Be that one kind of economical , suitable for use safety keeps watch the receiving system giving an alarm. Owe design the circuital simplicity. Procedure uses assembly language to compile and compose, structure is rational. The gear having the keyboard expanding a numerical code, giving an alarm exports, communication waits for a function with superordination.
