摘要
为拓宽RTK高精度定位技术的应用范围,解决无动力设备管理等问题,本文研究并设计了一套低功耗高精度定位系统,该系统可以实现RTK厘米级定位,整机选用低功耗的定位模块、4G模块和MCU,并使用一种自动休眠机制以延长续航时间,在有限的体积和电池容量下实现了长达20天的持续工作。设计的配套上位机可以查看装置的实时位置信息。系统完全独立运行,可以灵活应用在各种设备上,实现对车辆、无人机、无动力设备或人员的持续定位。
With the rise of automated vehicle management in recent years,how to achieve high-precision equipment positioning has become a hot topic.Existing studies rarely deal with the high-precision positioning of unpowered devices.In our study,a low-power high-precision positioning system is designed based on Real-Time Kinematic(RTK)technology and can match centimetre-level positioning.Low-power modules such as positioning modules,4G modules and Microcontroller Unit(MCU)were selected for the overall hardware part.A new working strategy that allows the machine to better balance the auto-sleep and working states for longer endurance.Compared to conventional designs,we achieved up to 20 days of continuous operation with limited size and battery.The system is fully self-contained and can be matched to a wide range of commercially available equipment,such as vehicles,drones,unpowered equipment or rescuers.The matching host computer can easily view real-time location information.This research presents new challenges for miniaturization and portability of positioning systems.
