Description
技术领域technical field

背景技术Background technique
高速公路超速行驶已成为高速公路交通事故的主要原因。根据高速公路路段最新高速路限速规定调整，高速公路对不同类型的车辆的限制速度不同。为了严查高速公路车辆超速的现状，高速公路上安装了车辆测速装置，查出超速车辆，并给予警告，减少交通事故的发生。现有技术中，通过高速公路出入口的摄像机测速系统算出车辆的平均速度与限制速度相比较，并结合沿高速公路设置的现场监控用测速仪和摄像机监控车辆的瞬时速度来判断车辆是否超车，这种方案的不足之处在于仅在出入口采用视频处理技术获取信息，不能提供全程的车速监控信息，至使许多司机投机取巧，在没被检测到的路段大胆超速；另一种通过给进入高速公路的司机发放RFID标签，该标签与高速公路上的用于读取RFID的多个读卡器通信后，将信息发送到后台服务器进行数据计算分析，查出超速车辆，但该系统光通信网铺设成本高、维护不方便，不能满足我国现代化交通快速发展的需求。Speeding on expressways has become the main cause of expressway traffic accidents. Adjusted according to the latest expressway speed limit regulations on expressway sections, the expressway has different speed limits for different types of vehicles. In order to strictly investigate the current situation of speeding vehicles on expressways, vehicle speed measuring devices are installed on expressways to detect speeding vehicles and give warnings to reduce the occurrence of traffic accidents. In the prior art, the average speed of the vehicle is compared with the speed limit calculated by the camera speed measurement system at the entrance and exit of the expressway, and the instantaneous speed of the vehicle is monitored by the on-site monitoring speedometer and the camera set along the expressway to judge whether the vehicle is overtaking. The disadvantage of this scheme is that it only uses video processing technology to obtain information at the entrance and exit, and cannot provide the whole vehicle speed monitoring information, so that many drivers are opportunistic and boldly speeding on undetected road sections; Drivers issue RFID tags, which communicate with multiple card readers on the expressway for reading RFID, and then send the information to the background server for data calculation and analysis to detect speeding vehicles, but the laying cost of the optical communication network of the system High and inconvenient to maintain, it cannot meet the needs of the rapid development of China's modern transportation.
