详细介绍离散多音频调制原理，对mmse信道缩短法和基于其他代价函数的时域均衡器设计方法的进行了系统全面的分析和阐述，分析了各自的优缺点；对时域均衡器结构进行研究；仿真比较了各种时域均衡方法，为进行时域均衡器设计时均衡算法、均衡器结构的选择提供了有价值的参考。 - It realizes the functions of storing and transferring the information of fire alarm , displaying time , scanning keyboards , the safe maintenance of system and so on . the part of wireless communication is controlled by at89c2051 mcu , mainly realizing transmitting and receiving data between controller and other detectors . the external signals received by a wireless module are transmitted to mcu through shaping circuit , and the signals of mcu are transmitted by a wireless module through tone modulation circuit
人机交互部分以单片机c8051f020为核心,为用户提供一个良好的操作环境,实现了火灾报警信息的存储及调用、时间的显示、键盘的扫描、系统的安全维护等功能;无线通信部分由单片机at89c2051来控制,主要实现控制器与其它探测装置之间信号的无线发射和接收,无线通讯模块接收到的外部信号经过整形电路送入单片机,单片机发出的信号经过音频调制再由无线通讯模块发送出去,这样实现了数据的无线传输;本文还从节能的角度出发,兼顾性能的可靠性,提出了一种合理的无线火灾报警的信息传输模式。
