Abstract: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 135mm/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 6mm, which helps to improve the automation degree of the system.
