Description

Technical Field

[0001] The utility model relates to the field of ETC equipment, in particular to an ETC equipment with adjustable recognition range. Background Art

[0002] At present, the billing method used by ETC toll lanes on highways is to communicate with the on-board unit through the ETC device to obtain vehicle information, and then complete the billing and release of the vehicle. In the actual environment, vehicles often queue up when passing through the toll lanes. The rate at which the ETC device obtains information from the billing vehicles one by one is low, resulting in a low vehicle traffic rate. In addition, when the vehicle intervals are dense, the ETC device will communicate with multiple vehicles within the range, resulting in low efficiency in matching the vehicle information in the billing area with the information obtained by the ETC device, and even incorrect billing may occur. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem existing in the prior art that vehicles often queue up when passing through a toll lane, and the rate at which the ETC device obtains information from vehicles to be charged one by one is low, resulting in a low vehicle passage rate, and to provide an ETC device with an adjustable recognition range.

[0004] The utility model provides an ETC device with adjustable recognition range, comprising a box body, wherein the box body is rotatably provided with a camera device, the angle α between the axis of the camera device and the box body can be adjusted, and the angle α satisfies: 0°≤α≤180°.

[0005] By setting up a box body, various components of the ETC equipment are integrated into the box body, and the camera device is set on the surface of the box body so that the ETC equipment can be installed in one piece, and the camera device can be directed toward the lane to facilitate the distinction of the installation direction; the angle α between the axis of the camera device and the box body can be adjusted, and the direction of the axis of the camera device is the same as the direction of the line of sight of the camera device. During installation, the angle α is adjusted according to actual needs, so that the line of sight of the camera device covers different areas, thereby improving the flexibility of the use of the ETC equipment; by setting the angle α to meet: 0°≤α≤180°, the ability of the camera device's line of sight to cover the range of 0°≤α≤180° is improved, and the camera device can adjust the angle α in any direction within the surface of the box body, thereby improving the flexibility of the camera device and the coverage area of ​​the line of sight, and the information of multiple vehicles can be collected in a shorter time as needed, reducing the probability of collecting vehicle information one by one, thereby improving the vehicle passage rate.

[0006] Furthermore, the camera device may be connected to the box body via a universal joint, or may be connected to the box body via a rotating shaft or a fixing screw.

[0007] The box body is further provided with a connecting portion, and the box body can be connected to the mounting surface through the connecting portion. The angle between the surface of the box body where the connecting portion is located and the mounting surface is β, and the angle β can be adjusted through the connecting portion.

[0008] By providing a connecting portion, the box body can be connected to the installation surface through the connecting portion, which facilitates the installation of the box body.

[0013] The camera device includes a camera module, which is used to collect the vehicle's license plate color, license plate number, vehicle model, vehicle logo, traffic model, vehicle image and video.

[0014] By making the camera module capture and collect relevant information of the vehicle, the vehicle information can be constructed from multiple dimensions such as license plate color, license plate number, vehicle model, vehicle logo, traffic type, vehicle image and video, thereby improving the accuracy of vehicle recognition by the ETC device.

[0015] The camera module includes an image acquisition front-end unit and an image sensor unit.

[0016] The image acquisition front-end unit is used to collect light, that is, the image within the field of view coverage of the ETC device, and transmit the light to the image sensor unit.

[0021] An ETC device with adjustable recognition range also includes a main control module, which is used to match the information collected by the camera module with the information collected by the antenna module.

[0022] When the camera module and the antenna module collect information of multiple vehicles, the main control module matches the information collected by the camera module with the information collected by the antenna module to further improve the accuracy of vehicle identification by the ETC device.

[0023] The camera device and the connecting part are respectively arranged on two sides of the box body opposite to each other.

[0024] By arranging the camera device and the connecting part opposite to each other on both sides of the box body, it helps to balance the overall weight distribution of the ETC equipment and reduce stability problems caused by uneven weight.

[0025] Furthermore, the camera device and the connecting portion may also be arranged on the same surface of the box body.

[0026] The box body is provided with a cavity and a fixing screw, the camera device is arranged in the cavity, the contact surface between the camera device and the cavity is a spherical surface, and the fixing screw can pass through the cavity and abut against the camera device.

[0027] By setting the contact surface as a spherical surface, the camera device can be adjusted in multiple directions, providing greater flexibility and a wider viewing angle. At the same time, the spherical contact surface can distribute force more evenly, reduce local stress concentration, and help protect the camera device and the box body. By setting a fixing screw, after the position of the camera device is adjusted, the fixing screw can be abutted against the camera device to limit the rotation of the camera device.
