Example Embodiment
[0032] Example 1:
[0033] This embodiment includes a lane master controller 1, a license plate recognition unit 3, an antenna 4, an electric railing 5, a fee display 6, a pole drop coil 7 and a lane camera 8. The antenna 4 is projected diagonally downward to form an antenna communication coverage area 2. Vehicle isolation devices 11 are installed on both sides of the communication coverage area 2. The lane master controller 1 is connected to the license plate recognition unit 3, antenna 4, electric railing 5, toll display 6, rod drop coil 7 and lane camera 8, respectively. The lane master controls Lidar 9 is connected to device 1. The antenna 4 and the lidar 9 are installed on the gantry 10, the fee display 6 is installed in front of the electric railing 5, the drop coil 7 is installed behind the electric railing 5, the lane camera 8 is installed behind the electric railing 5, and the license plate recognition unit 3 focal length Aim at the far end of the antenna communication ...
Example Embodiment
[0043] Example 2:
[0044] In this embodiment, figure 1 The electric railing 5, the fee display 6, the pole drop coil 7, and the lane camera 8 move in the direction of the oncoming vehicle relative to "Example 1". The antenna communication coverage area 2 is basically flush with the electric railing 5, and the antenna communication coverage area 2 The distance between the proximal end and the electric railing 5 is close to 0 or a negative number, and the other is the same as in "Example 1".
Example Embodiment
[0045] Example 3:
[0046] In this embodiment, figure 1 The electric railing 5, the toll display 6, the pole drop coil 7, and the lane camera 8 move in the direction of the vehicle relative to "Example 1". The electric railing 5 is similar to the electric railings installed in the manual toll lane or the automatic truck lane. The antenna The distance between the near end of the communication coverage area 2 and the electric railing 5 is increased. In this embodiment, the first vehicle can pick up the card at the automatic card issuing machine or be processed by the toll collector. After completing the card picking, charging, or manual guidance to leave the lane, the system can process subsequent vehicles.
