[0049] For example, Figure 2The tunnel control system principle block diagram is shown, Figure 3 The tunnel control system principle block diagram is shown. The high-definition camera, millimeter wave radar, laser radar and vehicle detector collect visual information, speed information, acceleration information, distance information and traffic condition information of the vehicle, and send the information to the data communication module (a data acquisition board) through various specifications of sensor data interfaces. When the monitoring server detects a vehicle accident in the tunnel, a pre-warning control signal is sent to the second wireless communication module of each pre-warning area outside the tunnel through the first wireless communication module.
