摘要
设计了一种由离子型烟雾检测报警器MC14468、AT89C51单片机、单片射频收发器nRF401构成的火灾自动报警系统。该系统分为检测发送部分和接收控制部分,采用单片机的多机通信模式和串行传输方式实现数据的传输。由于引入了无线通信技术为核心的nRF401和MC14468,系统的性能大大提高,且具有较高的可靠性。
An automatic fire alarm system is designed based on an iron-type smoke detector MC14468, microeontroller AT89C51 and a radio frequency transceiver nRF401. The system includes the part of detecting and sending and the part of receiving and control. The multi machine communication mode and serial transmission style are used to achieve data transmission. By introducing nRF401 and MC14468, the system is improved greatly in performance and has high responsibility.
