一种VIP车辆无阻塞通行控制系统的配时方法，利用云平台控制中心分别控制道路交叉口信号灯控制器以及道路交叉口传感器来实现VIP车辆的无阻塞通行，所述通行控制系统的配时方法包括以下步骤：A timing method for a VIP vehicle non-blocking passage control system, which utilizes a cloud platform control center to respectively control a road intersection signal light controller and a road intersection sensor to realize the non-blocking passage of VIP vehicles, and the timing method for the passage control system Include the following steps:

S1、通过道路交叉口传感器检测和识别VIP车辆，并上传至云平台控制中心；S1. Detect and identify VIP vehicles through road intersection sensors, and upload them to the cloud platform control center;

S2、云平台控制中心根据道路交叉口的实时道路相位以及VIP相位来控制道路交叉口信号灯控制器，保证VIP车辆的无阻塞通行，其中相位是指道路交叉口一个方向的车流，VIP相位是指VIP车辆所处的相位；S2. The cloud platform control center controls the road intersection signal light controller according to the real-time road phase and VIP phase of the road intersection to ensure the unobstructed passage of VIP vehicles, where the phase refers to the traffic flow in one direction of the road intersection, and the VIP phase refers to The phase in which the VIP vehicle is located;

S3、当道路交叉口传感器检测到VIP车辆已完全通过此道路交叉口，则停止检测VIP车辆，并恢复此道路交叉口的正常通行；S3. When the road intersection sensor detects that the VIP vehicle has completely passed through the road intersection, it stops detecting the VIP vehicle and resumes normal traffic at the road intersection;

在道路交叉口传感器对VIP车辆实现检测和识别之前，需要云平台控制中心对VIP车辆发出的请求指令进行审批，包括以下步骤：Before the road intersection sensors can detect and identify VIP vehicles, the cloud platform control center needs to approve the request instructions sent by the VIP vehicles, including the following steps:

X1、VIP车辆发出请求指令，云平台控制中心接收指令进行审批，并获取审批通过后的VIP车辆信息，云平台控制中心根据VIP车辆信息设定出发地、目的地和沿途路线，并依据云平台控制中心存储的城市路网模型生成VIP车辆经过的道路交叉口信息，其中VIP车辆信息包括车牌号、车辆类型、车队长度以及VIP通行执行时间段；X1. The VIP vehicle sends a request command, the cloud platform control center receives the command for approval, and obtains the VIP vehicle information after the approval. The cloud platform control center sets the departure point, destination and route according to the VIP vehicle information, and according to the cloud platform The urban road network model stored in the control center generates the road intersection information passed by the VIP vehicle, where the VIP vehicle information includes the license plate number, vehicle type, fleet length and the VIP traffic execution time period;

X2、判断当前时间段是否处于VIP通行执行时间段，当处于VIP执行时间段内，则执行步骤X3，否则，重新进行判断；X2. Determine whether the current time period is within the VIP pass execution time period. If it is within the VIP execution time period, perform step X3, otherwise, make a new judgment;

由此，当VIP车辆到达道路交叉口时，通过步骤S2实现云平台控制中心分别控制道路交叉口信号灯控制器以及道路交叉口传感器来实现VIP车辆的无阻塞通行，步骤S2具体为：Thus, when the VIP vehicle arrives at the road intersection, the cloud platform control center controls the road intersection signal light controller and the road intersection sensor to realize the non-blocking passage of the VIP vehicle through step S2, and step S2 is specifically:

K1、道路交叉口传感器开始定位VIP车辆，获取当前路段内的VIP车辆及其行驶速度v；K1. The road intersection sensor starts to locate the VIP vehicle, and obtains the VIP vehicle in the current road section and its driving speed v;

K2、当道路交叉口传感器识别到VIP车辆时，道路交叉口信号灯控制器分别判断道路目前相位是否在VIP相位上，当VIP车辆不在VIP相位上，则立即调整到VIP相位上，当道路目前相位在VIP相位上时则不进行调整，若预计VIP车辆到达交叉口时的实时道路相位与VIP相位冲突，则在交叉口的信号灯的上一个相位结束后，通过云平台控制交叉口信号灯控制器使信号灯全红，将原本应该的交叉口道路相位改为VIP相位，若预计车辆到达道路交叉口的实时道路相位与VIP相位相同，则根据VIP车辆通过交叉口的时间来将相位时长进行延长，其中相位时长根据VIP车辆到达道路交叉口时间和通过道路交叉口的时间进行确定，并将此道路交叉口命名为N；K2. When the road intersection sensor recognizes the VIP vehicle, the road intersection signal light controller determines whether the current phase of the road is on the VIP phase. When the VIP vehicle is not on the VIP phase, it will immediately adjust to the VIP phase. When the current phase of the road is on the VIP phase When it is on the VIP phase, it will not be adjusted. If the real-time road phase when the VIP vehicle arrives at the intersection is expected to conflict with the VIP phase, after the previous phase of the signal light at the intersection ends, the cloud platform will control the intersection signal light controller to make The signal light is all red, and the original road phase of the intersection is changed to the VIP phase. If the real-time road phase when the vehicle arrives at the road intersection is expected to be the same as the VIP phase, the phase duration is extended according to the time that the VIP vehicle passes through the intersection. The phase duration is determined according to the time when the VIP vehicle arrives at the road intersection and the time it passes through the road intersection, and the road intersection is named N;

此时，VIP车辆已经通过了道路交叉口N，通过步骤S3实现道路交叉口N的正常通行，步骤S3具体为：At this time, the VIP vehicle has passed the road intersection N, and the normal passage of the road intersection N is realized through step S3, and step S3 is specifically:

After receiving the information that the VIP vehicle has completely passed the road intersection N, the cloud platform control center first detects whether there is a next road intersection N+1, and when it does not detect the existence of the next road intersection N+1 When the current VIP pass is ended and the information is sent to the cloud platform control center for display, when the existence of the next road intersection N+1 is detected, it will immediately notify the next intersection N that the VIP vehicle will reach. +1 signal light controller, and send the distance W1 from road intersection N to road intersection N+1 and predicted travel time T01 to road intersection N+1 signal light controller, where predicted travel time T01 is based on distance W1 and VIP vehicles The driving speed v is obtained, and it is named by analogy;

Y3、云平台控制中心通过道路交叉口传感检测到VIP车辆已经完全通过道路交叉口N+1的信息后，并在道路交叉口N+1处使用步骤S2，通过道路交叉口N+1的时刻命名为T2进行存储，T2-T1为VIP车辆通过道路交叉口N到道路交叉口N+1的实际行程时间，并将实际行程时间T2-T1发送到云平台控制中心进行显示，以此类推；Y3. After the cloud platform control center detects the information that the VIP vehicle has completely passed the road intersection N+1 through the road intersection sensor, and uses step S2 at the road intersection N+1, through the road intersection N+1 The time is named as T2 for storage, T2-T1 is the actual travel time of the VIP vehicle through the road intersection N to the road intersection N+1, and the actual travel time T2-T1 is sent to the cloud platform control center for display, and so on. ;

Y4、当云平台控制中心接收到VIP车辆已经驶过最后一个道路交叉口的信息后，通行控制系统结束工作，发送至云平台控制中心进行显示；Y4. When the cloud platform control center receives the information that the VIP vehicle has passed the last road intersection, the traffic control system ends its work and sends it to the cloud platform control center for display;

当云平台控制中心检测到VIP车辆未按规划路线行驶，云平台控制中心强制结束本次VIP通行重新规划路线；When the cloud platform control center detects that the VIP vehicle does not travel according to the planned route, the cloud platform control center forcibly ends the VIP pass and re-plans the route;

所述通行控制系统还包括道路交叉口摄像头，配时方法通过道路交叉口摄像头寻找识别VIP车辆；The traffic control system further includes a road intersection camera, and the timing method uses the road intersection camera to find and identify VIP vehicles;
