一种双CPU主从式毫米波雷达系统

我国国土辽阔，地形复杂，丘陵及山区较多，气象条件复杂，为了实现安全、可靠的供电，迫切需求自动化、现代化的巡检技术手段。目前，国网公司正逐步采用无人机技术来提高架空输电线路的运行效率和质量，无人机已成为电网巡检的重要技术手段。分析目前架空输电线路巡检的紧迫形势，及现有无人机巡检技术的优点及机载避障技术的缺陷，提出了一种用于输电线路巡检无人机的毫米波避障雷达，该雷达系统采用双CPU主从搭配模式，可有效测量出障碍物距离，为无人机巡检保驾护航。

A Master-Slave Dual CPU Millimeter Wave Radar System

China has a vast territory, complicated terrain, many hills and mountains, and complicated meteorological conditions. The automatic and modern inspection technologies are the urgent needs to achieve safe and reliable power supply. At present, the company is gradually adopting UAV technology to improve the efficiency and quality of overhead transmission lines. UAV has become an important technical means for grid inspection. This paper analyzes the current situation of overhead transmission line inspection and the advantages of existing UAV inspection technology and the defects of airborne obstacle avoidance technology. A millimeter wave obstacle avoidance radar for transmission line patrol UAV is proposed. The radar system adopts dual CPU master slave mode, it can measure the distance of the obstacle effectively and escort the UAV patrol.
