摘要
采用FSK调制/解调芯片nRF401与89C51微型处理器实现小区远程无线自动报警器的设计方案。给出了系统的硬件电路组成逻辑框图和部分MCS51程序设计流程图。论述了系统中应用的报警数据格式与准确报警的策略。分析了系统报警时延存在的原因,在住宅小区内可以实现远程无线自动与网络化报警。
A plan of designing the circuit of realizing intelligent alarm, which utilizes FSK modulations/demodulations wireless receiver/transceiver nRF401 and microprocessor 89C51 is presented. The frame chart of the system hardware and the designing flowing chart of software are given. Furthermore, the fragment of data using in the system is given in the discussion. Which can realize intelligently and grouped alarm in the ordinary district.
