摘　　要：针对目前地震、矿难营救方式单一,以及检测仪器定位遇难者位置准确度小的现象,采用就地语音报警与远处调频信号接收的方式设计了一种生命求救信号发生器。该信号发生器可以通过遇难者语音求救、系统报警、脉搏报警三种方式向搜救者提供求救信号,以实现快速营救遇难人员的目的。通过实践测试表明,该信号生发器具有工作稳定、信号检测灵敏度高、发射频率稳定、遇难者定位准确以及整机功耗小、携带方便等优点。In view of the present earthquake, mine rescue way is single, and the detecting instrument positioning victim location accuracy small phenomenon, in the voice alarm and distant FM signal received by the design of a life distress signal generator. The signal generator can to rescue the victims, help voice alarm system, pulse three alarm modes provide a distress signal, fast rescue of victims to realize the purpose of. Through practical tests show that, the advantages of generator has the advantages of stable operation, signal detection sensitivity, stable emission frequency, the victims of accurate positioning and the whole power consumption, easy to carry the signal.
