Power control method and device

The invention relates to a power control method and device. The method comprises the following steps: acquiring a frame error rate of target equipment in a positioning system; if the frame error rate is greater than a preset frame error threshold, determining a cause of the frame error rate; determining a power control strategy according to the cause; and executing a power adjustment operation based on the power control strategy to reduce the frame error rate of the target device to be within a preset frame error threshold. The positioning precision of the positioning system can be effectively improved. 本申请涉及一种功率控制方法及装置，其中该方法包括：获取定位系统中目标设备的误帧率；如果误帧率大于预设误帧阈值，确定误帧率的引发原因；根据引发原因确定功率控制策略；基于功率控制策略执行功率调整操作，以将目标设备的误帧率降低至预设误帧阈值之内。本申请能够有效提升定位系统的定位精度。
