Embodiment 1

[0026] Such as figure 1 As shown, it includes a loop coil detector 1, two groups of ultrasonic detectors 2, 3 and a reverse detection controller 4. Wherein, the loop coil detector 1 is arranged perpendicular to the driving direction on the toll lane in front of the electric railing; two sets of ultrasonic detectors 2 and 3 are arranged at the side of the loop coil detector 1 on the lane.

[0027] Such as figure 2 As shown, the installation height of the two sets of ultrasonic detectors 2 and 3 is 0.7m from the plane of the roadway. The distance between two groups of ultrasonic detectors 2, 3 is 1.2m.

Embodiment 2

[0029] Present embodiment is except following feature, and other is all identical with embodiment 1: as image 3 As shown, it includes a loop coil detector 1 and two axle sensors 5,6. Two axle sensors are arranged in the ring coil detector perpendicular to the driving direction, and the vertical distance between the two axle sensors 5 and 6 is 0.5m.

Embodiment 3

[0031] Present embodiment is except following feature, and other is all identical with embodiment 1,2: as Figure 5 As shown, it includes an annular coil detector 1, two groups of ultrasonic detectors 2, 3 and two axle sensors 5, 6; two groups of ultrasonic detectors are arranged on the same side or both sides of the toll lane facing the annular coil detector, the Two sets of wheel axle sensors are arranged in the loop coil detector perpendicular to the driving direction. The distance between the two sets of ultrasonic detectors is 1.2m; the installation height of the ultrasonic detectors from the lane plane is 0.7m. The distance between two groups of wheel axle sensors is 0.5m; each group of wheel axle sensors has 1~2 pieces; the length of wheel axle sensors is 1.2m~4.5m.

Abstract

The invention discloses a vehicle reversing detection device at a toll lane in a toll station. The vehicle reversing detection comprises a ring coil detector at an electric handrail machine, two groups of ultrasonic detectors or (and) two groups of axle sensors, and a reversing detection controller, wherein the ring coil detector, and the two groups of ultrasonic detectors or (and) the two groups of axle sensors are respectively connected with the reversing detection controller; the ring coil detector is arranged on the toll lane at the automatic handrail machine; the two groups of ultrasonic detectors are over against the ring coil detector and are arranged on one side or two sides of the lane; and the two groups of axle sensors are vertical to the direction of travel and are arranged on the lane at the ring coil detector. The vehicle reversing detection device can be used for accurately recognizing the direction of travel of a vehicle passing by the toll lane and preventing cheat behaviors such as a phenomenon that the driver of a vehicle takes more cards during a reversing process.

Description

technical field [0001] The invention relates to the technical field of toll monitoring systems for toll roads, in particular to a vehicle reversing detection device in toll lanes of toll stations. Background technique [0002] Most toll roads in my country adopt a closed management method. Drivers obtain a pass card at the entrance, and the pass card records information such as the vehicle type, time, direction, and entrance toll station, and pays the toll at the exit according to the vehicle type and driving distance recorded in the pass card. However, many cheaters and fee evaders often take advantage of the flaws in the toll system and cheat by reversing the card. At present, reversing the card has become the most common way of cheating. The premise of reverse card cheating is to obtain multiple access cards. Due to the imperfection of the current lane detection facilities, it is impossible to accurately judge the driving direction of the vehicle after taking the card. ...
