摘要
为了测定目标点相对观测点的相对坐标位置,提出了一种基于XMC4200单片机的硬件和软件设计方案,并设计了相应的坐标观测装置。利用电子罗盘、旋转编码器、激光测距机及GPS定位装置获取解算目标点坐标所需的坐标姿态信息,可将坐标姿态信息通过显示面板及手持终端进行显示,利用手持终端还可对目标点的磁偏角进行动态设置补偿。整个系统采用可充电式12V锂电池组进行供电,使得系统具有较好的便携性。经过实际测试,该便携式坐标观测装置具有较高的观测精度和较好的使用效果及应用前景。
In order to determine the relative position of target point to observation point, a design scheme of hardware and software based on XMC4200 microcontroller is proposed, and the corresponding coordinate observation device is designed. The attitude information needed to solve the target point coordinates is obtained by the electronic compass, rotary encoder, laser range finder and GPS instrument. The position information can be displayed on the display panel and handheld terminal. With a handheld terminal, the magnetic deviation can be setted up. The system is powered with a rechargeable 12 V lithium battery, therefore it has good portability. The experiment verifies that this portable instrument has high observation precision, is very effective, and have good application prospect.
