GPS在场地集装箱轮胎吊上的应用

Application of GPS in Rubber-Tyred Gantry Crane

GPS结合场地集装箱轮胎吊大车编码器的性能,实现RTG在堆场上X/Y方向的定位,而编码器则实现了GPS定位的校验和推导功能,两者相互补偿,既提高了定位信号的更新速度,弥补GPS定位刷新率较低的不足,又消除了编码器长时间工作产生的累计误差,保证定位的精确性。

Global Positioning System (GPS) and the coder of Rubber-Tyred Gantry Crane (RTG) make a couple. GPS can position RTGs in X direction and Y direction, while the coder can checkout and calculate the positioning signal of GPS,thus GPS and coder complement each other. So,not only the updating speed of GPS is improved,but also the error accumulated of the coder is eliminated.
