针对进口芯片设计标识卡功耗过高导致电池充电、更换频繁，维护难度大，不适用于煤矿井下对各种矿车车皮长时间位置跟踪的问题，设计了基于国产化芯片的矿车车皮精确定位标识卡；介绍了硬件和软件2方面的降低车皮标识卡功耗设计：硬件采用全国产化芯片设计；软件优化定位网络算法，自适应调整射频发射功率。测试结果表明：硬件与软件相结合保证了定位精度不变、通信距离提高，使得产品成本降低，延长了车皮标识卡使用寿命，提升了车皮井下辅助运输效率和周转率。

Aiming at the problem that high power consumption of designed identification card with imported chip leads to frequent battery charging, frequent replacement and difficult maintenance, which is not suitable for the long-term position tracking of various vehicles in the coal mine, a precise positioning identification card based on the domestic chip for mine vehicles is designed. This paper introduces the design of hardware and software to reduce the power consumption of the identification card. The hardware adopts the domestic chip design; the software optimizes the positioning network algorithm and adaptively adjusts the RF transmission power. The test results show that the combination of hardware and software ensures constant positioning accuracy, improves communication distance, reduces product costs, extends the service life of the identification card, and improves the efficiency and turnover rate of underground auxiliary transportation of the vehicles.
