背景技术Background technique
随着城市化进程推进，交通安全问题成为不可避免的问题。常见的交通问题很大一部分是由驾驶员的非法变道、超速等造成，近年来的交通监控成为预防交通事故的有效手段之一。With the advancement of urbanization, traffic safety issues have become inevitable. A large part of common traffic problems are caused by illegal lane changes and speeding of drivers. In recent years, traffic monitoring has become one of the effective means to prevent traffic accidents.
现有的道路巡检大部分为采用警用巡逻车辆巡检以及定点安装监控摄像，巡检成本高，巡检范围小，只能得到巡逻车辆周围的交通信息，同样的，监控摄像可视范围小，存在盲区。Most of the existing road inspections use police patrol vehicles and fixed-point installation of monitoring cameras. The cost of inspections is high, and the scope of inspections is small. Only traffic information around the patrol vehicles can be obtained. Similarly, the visible range of surveillance cameras Small, there are blind spots.
与此同时，近年来多旋翼无人机得到快速发展，多旋翼无人机由于其结构简单、灵活多变等优势无论在军事还是民用上都得到了广泛的应用。无人机具有重量轻、体积较小、便于携带、成本低、能自动飞行，灵活性好、支持多种巡检模式等优点，将无人机应用于交通巡逻，能够增大巡逻范围，在较大范围内保证事故发生时第一时间了解到情况，并将画面回馈给地面控制中心，及时出警。At the same time, multi-rotor UAVs have developed rapidly in recent years. Due to their simple structure, flexibility and other advantages, multi-rotor UAVs have been widely used in both military and civilian applications. UAVs have the advantages of light weight, small size, portability, low cost, automatic flight, good flexibility, and support for multiple inspection modes. Applying UAVs to traffic patrols can increase the patrol range. In a large area, it is guaranteed that the situation will be understood at the first time when the accident occurs, and the screen will be fed back to the ground control center, and the police will be dispatched in time.
但是，无人机的电池容量有限，续航时间较短，成为其应用的一大瓶颈。However, the battery capacity of drones is limited and the battery life is short, which has become a major bottleneck for its application.
而无线供电技术（无线传能）装置不需要用电缆将设备与供电系统连接，便可以直接对其进行快速充电。加之非接触快速充电能够布置在多种场所，又可以为各种类型的设备提供充电服务，使随时随地充电变为可能。也可为无人机的应用提供充电。The wireless power supply technology (wireless energy transfer) device does not need to use a cable to connect the device to the power supply system, and can directly charge it quickly. In addition, non-contact fast charging can be arranged in a variety of places, and can provide charging services for various types of equipment, making it possible to charge anytime and anywhere. It can also provide charging for drone applications.
