本文介绍了声波探生系统在城市灾害救援中的应用,采用无线通信模块nRF24E1构建系统的无线传输机制,克服了以往有线探生设备的局限,具有较大范围的适用性。发射端实现微型化、低功耗设计,接收端可同时处理多路信号并具友好的人机交互。(该研究得到了国家“十一五”科技支撑计划项目《智能化电磁波生命探测装备研发》的支持,专题编号Abstract: The application in the disaster rescue of the life detection system base on sound wave is introduced. The wireless module nRF24E1 composes the wireless transmission architecture of the system to overcome the limitation of the wire system. The transmitter achieves micromation design and low power consumption. The receiver deals with multi-signals simultaneously and owns good man-machine conversation.Key words: disaster rescue; life detection; frequency-hopping communication
