摘　　要：通过分析基于北斗高精度定位、毫米波雷达多传感融合的多级定位技术,结合RFID、图像识别的方法,解决移动式集装箱装卸机械(集装箱正面吊、堆高机等)的关键信息采集问题。此方法通过采用北斗RTK高精度定位实现装卸机械的一级定位,然后通过采用MEMS倾角传感器、毫米波雷达实现装卸机械吊具的二级精确定位;基于二级定位结果,结合自动跟踪技术、图像识别技术,实现集装箱箱号的自动识别、集装箱的定位;采用多级定位,结合无源RFID技术,实现集卡汽车的定位;采用太阳能供电、系统低功耗设计,实现系统的低功耗运行。此方法不仅解决了移动式装卸机械的定位问题,也解决了集装箱和作业集卡车的定位问题,具有广阔的应用前景。Upon the analysis of the multi-stage positioning technology based on BeiDou high-precision positioning and millimeter-wave radar multi-sensor fusion, RFID and image recognition were employed to solve the key information collection problem of mobile container handling machinery(container front crane, stacker, etc.). This method adopted BeiDou RTK high-precision positioning to realize the primary positioning of handling machinery and the MEMS inclinometer and millimeter wave radar to realize the secondary precise positioning of the handling machinery spreader. Given the results of secondary positioning, automatic tracking technology and image recognition technology were used to achieve the automatic identification of container numbers and the positioning of containers. Multi-stage positioning and passive RFID technology were adopted to position container trucks. Solar power supply and low power consumption design were utilized to realize the low power consumption operation of the system.This method solves the positioning problems of mobile handling machinery, containers, and working container trucks, which has a broad application prospect.
