摘　　要：针对煤矿现场智能化矿山建设及提升井下作业人员生命安全实际需要,分析传统信息矿灯成本高、功耗大,WiFi无线射频置于灯头等缺点,设计一种低功耗、低成本精确定位语音对讲信息矿灯;通过对UWB定位技术和WiFi无线通信技术休眠机制的研究,延长了矿灯使用寿命;对语音信号压缩编码算法研究,将无线射频与灯头分离,采用单芯片声码器,降低了成本;定位语音对讲信息矿灯不仅实现高精度定位功能,同时,在危险状态下可以紧急呼救、群组撤离、各种灾害可靠逃生路线信息导播等,为矿工井下作业提供更安全有力的保障。Aiming at the actual needs of intelligent mine construction and improving the life safety,the paper analyzes the disadvantages of traditional information miner’s lamp,such as high cost,high power consumption,WiFi radio frequency placed in the cap.A miner’s lamp of low power consumption and low cost is designed.Through the study of UWB positioning technology and the sleep mechanism of WiFi wireless communication technology,the service life of mine lamp is extended;to study the speech signal compression coding algorithm,the radio frequency and lamp cap are separated,and the single chip vocoder is adopted,which reduces the cost.Locating voice intercom information miner’s lamp not only realizes high-precision positioning function,but also can call for emergency help,group evacuation and broadcast information of reliable escape routes of various disasters under dangerous conditions,providing a safer and stronger guarantee for miners’underground operations.
