技术领域technical field

背景技术Background technique
交通灯一般为周期性设置,在交通控制系统中,对于交通的特殊需求,没有过多的考虑,例如:当有特殊需求的车辆如消防车,救护车等急需通过路口时,法规规定它们可以在确保安全的前提下,闯红灯,但是当遇到城市交通发生严重堵塞时,私家车只能依次排队通过交叉路口,没办法给紧急交通车辆让道。Traffic lights are generally set periodically. In the traffic control system, there is not too much consideration for the special needs of traffic. For example: when vehicles with special needs such as fire trucks and ambulances need to pass through the intersection urgently, the regulations stipulate that they can On the premise of ensuring safety, run a red light, but when there is a serious traffic jam in the city, private cars can only line up to pass the intersection one by one, and there is no way to give way to emergency traffic vehicles.
专利CN201510337760.6提出了一种交通应急干预系统和方法,通过智能摄像头对车辆的图像进行采集和识别,在出现紧急车辆时,计算其运行路线和可能经过的红绿灯编号,从而对红绿灯进行控制,这种方法虽然可以使得紧急车辆快速通过,但是需要的图像识别技术精度非常高,而且计算量很大,消耗成本过高,不适合普遍推广。Patent CN201510337760.6 proposes a traffic emergency intervention system and method, which collects and recognizes images of vehicles through smart cameras, and calculates its running route and possible traffic light numbers when an emergency vehicle appears, so as to control the traffic lights. Although this method can allow emergency vehicles to pass quickly, it requires very high accuracy of image recognition technology, a large amount of calculation, and high consumption costs, so it is not suitable for general promotion.

上述系统的工作流程如图2所示,该系统在工作时,首先状态监测模块1中的摄像头11对来往车辆进行拍摄,如果声音传感器捕捉到紧急车辆发出的声音信号,则传输至控制模块2,控制模块2对摄像头11发出控制信号对当前经过的车辆车牌进行识别,如果声音传感器未捕捉到声音信号,则摄像头11对来往车辆的车牌按照顺序进行识别,摄像头11将捕捉到的车牌图像传输至图像处理器12,由于摄像头对汽车车牌的图像捕捉是现有的交通管控中最基本的实现手段,因此对图像识别的精度要求比较低,易于实现,经图像处理器12提取滤波后,通过无线信号发射器14传输至控制模块2,控制模块2首先通过无线信号接收器21接收图像信号,继而传输至MCU控制芯片22,MCU控制芯片22通过交换机23连接至交通管理中心服务器3,将图像与交通管理中心服务器3的图像进行比对,如果识别出该车牌对应的车辆为紧急车辆,则测速仪13对车牌对应的车辆进行测速,并将速度传输至MCU控制芯片22,MCU控制芯片22根据速度计算该车辆到达交通灯4的时间t,并检测该交通灯4的情况,如果为绿灯且绿灯的时间大于t+8s,则控制器对控制执行组件24发出不做任何操作的信号,如果绿灯时间小于t+8s,则控制器控制延时器延长绿灯的时间至t+8s,以防止紧急车辆还没通过路口红绿灯就变色从而导致交通事故;如果为红灯且红灯的时间小于t+10s,则控制器对控制执行组件24发出不做任何操作的信号,从而让行人有足够的时间通过十字路口,如果红灯时间大于t+10s,则控制器控制延时器缩短红灯时间至t+10s,以便紧急车辆可以快速通过红绿灯。The workflow of the above-mentioned system is shown in Figure 2. When the system is working, first the camera 11 in the state monitoring module 1 takes pictures of passing vehicles, and if the sound sensor captures the sound signal sent by the emergency vehicle, it is transmitted to the control module 2 , the control module 2 sends a control signal to the camera 11 to identify the current passing vehicle license plate, if the sound sensor does not capture the sound signal, the camera 11 recognizes the license plates of the passing vehicles in order, and the camera 11 transmits the captured license plate image To the image processor 12, since the image capture of the vehicle license plate by the camera is the most basic means of realization in the existing traffic control, the accuracy requirements for image recognition are relatively low and easy to implement. After the image processor 12 extracts and filters, pass The wireless signal transmitter 14 transmits to the control module 2, and the control module 2 first receives the image signal by the wireless signal receiver 21, and then transmits to the MCU control chip 22, and the MCU control chip 22 is connected to the traffic management center server 3 by the switch 23, and the image signal Compared with the image of the traffic management center server 3, if it is recognized that the vehicle corresponding to the license plate is an emergency vehicle, the speedometer 13 measures the speed of the vehicle corresponding to the license plate, and transmits the speed to the MCU control chip 22, and the MCU control chip 22 Calculate the time t when the vehicle arrives at the traffic light 4 according to the speed, and detect the situation of the traffic light 4, if it is a green light and the time of the green light is greater than t+8s, then the controller sends a signal of no operation to the control execution component 24, If the time of the green light is less than t+8s, the controller controls the delayer to extend the time of the green light to t+8s, so as to prevent the emergency vehicle from changing color before passing the traffic light at the intersection and causing traffic accidents; if it is a red light and the time of the red light is less than t+10s, then the controller sends a signal of no operation to the control executive component 24, so that pedestrians have enough time to pass through the intersection, if the red light time is greater than t+10s, the controller controls the delayer to shorten the red light The time is up to t+10s so that emergency vehicles can quickly pass through the traffic lights.
