基于GIS的工程测绘机器人自动定位系统设计

Design of Auto-positioning System for Engineering SurveyingRobot Based on GIS

根据传统定位系统在传递信息时采用惯性传感器,导致调试结果误差大的问题,设计了基于GIS的工程测绘机器人自动定位系统;根据工程测绘机器人自动定位系统总体结构,将系统分为硬件系统和软件系统两部分;通过s2c2440微处理器向ONPYHON480图像传感器中发送采集图像信号,经过135mm/F2.8全面幅远摄定焦光学镜头将图像信号转换为电子信号,通过直接内存存取系统传送到存储单元之中;设计电源电路为工程测绘机器人自动定位系统提供设备电力供应,避免电源本身所产生杂波对系统产生干扰;选择PDU模式收发短信息,利用GIS技术开发电子地图,实现工程测绘机器人自动定位;调试结果表明,该系统具有定位结果误差小的特点,静态测试点定位误差在3mm以内,动态测试点定位误差在6mm以内,辅助提升系统自动化程度。

According to the traditional positioning system,the inertial sensor is used in the transmission of information,which leads to the error of the debugging result.The automatic positioning system of engineering mapping robot based on GIS is designed.According to the overall structure of the automatic mapping system of engineering mapping robot,the system is divided into two parts:hardware system and software system.The image signal is sent to the ONPYHON480 image sensor through the s2c2440 microprocessor,and the image signal is converted into an electronic signal through a 135 mm/F2.8 full-width telephoto focusing lens,which is transmitted to the storage unit through the direct memory access system.The power supply circuit is designed to provide equipment power supply for the automatic mapping system of the engineering mapping robot,so as to avoid the interference generated by the power source itself.Select PDU mode to send and receive short messages,and use GIS technology to develop electronic maps to realize automatic positioning of engineering surveying robots.The debugging results show that the system has the characteristics of small error in positioning results.The positioning error of static test points is within 3mm,and the positioning error of dynamic test points is within 6 mm,which helps to improve the automation degree of the system.
