Research and Development on IGPS Receiver for Flexible Assembly Platform of Large and Thin-Walled Parts

主要介绍了Indoor GPS(iGPS)测量系统接受器的研制,iGPS测量系统原理是基于区域GPS三维空间测量技术,利用红外扇面激光代替卫星微波信号向全局范围内发送,传感器接受激光信号之后,经过电路处理将其处理成脉冲信号,利用现场可编程门列FPGA,设计数字信号处理单元,测量出激光信号之间的时间间隔,根据后方角度交会原理计算出接收器当前空间位置三维坐标值。系统应用于大型薄壁件制造的柔性自动化装配平台实现实时在线反馈调整,得到满意的效果。

Research and development on measurement system receiver using indoor GPS（iGPS）are introduced.The measurement principal of this system using iGPS is based on the regional GPS three-dimensional measurement techniques.Instead of the satellite microwave,the infrared fan laser was used to send signals into the global scope.And then,the laser signal received by the sensor was processed into a pulse signal through the circuit.The local programmable gate column FPGA was adopted to design the digital signal processing unit so as to measure the time interval between the laser signal.After all,three-dimensional coordinate values of the current space location of receiver were calculated according to the principle of the rear angle of intersection.This system was used in the flexible and automation assembly platform for large and thin-walled parts and the real-time online feedback and adjustment is achieved with a satisfactory result.
