摘要
针对目前人员定位系统中标识卡电池使用时间短、维护工作量大的问题,提出采用低频唤醒技术降低电池工作时间,从而延长电池寿命,即设置标识卡在矿工下井时间之外为休眠状态,当矿工下井时使用低频信号接收器唤醒标识卡。测试结果表明,采用低频唤醒技术可以很好地改善标识卡电池的寿命,当信号发射周期为1-3s时,电池使用寿命延长为原来的2.7倍以上,并且标识卡的发射周期越短,改善效果越好。
In view of problem of short service time and great maintenance workload of identification card battery used in current personnel positioning system,the paper proposed to apply low-frequency wake-up technology to reduce battery operating time,thereby extend battery life,namely set dormant state for identification card when the miners are outside of the mine,and use low-frequency signal receiver to wake up the identification card when the miners go down the mine.The test results show that the use of low-frequency wake-up technology can greatly improve battery life of identification card,when the signal transmission period is 1-3s,the battery life is extended to more than 2.7times of the original,and the improving effect is better as the transmission period becomes shorter.
