Description

Technical Field

[0001] The utility model relates to the technical field of green pass vehicle detection, in particular to a parking and reversing detection device during the detection process of green pass vehicles on highways. Background Art

[0002] Currently, the inspection of green channel vehicles mainly adopts the principle of X-ray radiation imaging. The fan-shaped rays emitted by the X-ray transmitter penetrate the closed compartment and the cargo loaded therein, and are received by the X-ray receiver installed on the other side. Because the density of the various parts of the various items loaded in the vehicle varies, the degree of absorption of X-rays varies, resulting in different signal strengths output by the detector. After image processing, the strong and weak signals output by the detector can generate an image related to the outline and shape of the items loaded in the vehicle, which is displayed on the computer screen. By viewing the video, it is possible to see the items loaded in the closed compartment and distinguish whether there are mixed loads, empty loads, suspected dangerous goods, etc., thus achieving the inspection purpose;

[0003] Although the existing green channel lane vehicle inspection all adopts X-ray inspection, X-ray is a kind of ionizing radiation. If it is exposed for a long time or in high doses, it may cause damage to human cells and pose a risk to human health. Therefore, when a vehicle passes through the green channel, it will be quickly scanned and inspected and pass. However, during the inspection process, it is inevitable that some drivers and staff do not communicate well, resulting in the phenomenon of slow speed, parking or reversing during the inspection. However, when the vehicle enters the inspection channel and the X-ray is working, if the vehicle speed is too slow, parking or reversing, the X-ray machine will continue to work, thereby further increasing the harm to the human body. For this reason, the utility model provides a parking and reversing detection device during the green channel vehicle inspection process on a highway. Utility Model Content

[0007] It also includes a mounting bracket installed on the ceiling directly above the exit of the green pass detection channel, on which a millimeter-wave radar is installed facing the entrance of the green pass detection channel.

[0013] The present invention relates to a parking and reversing detection device for green-pass vehicle inspection on highways. The device uses the cooperation of ground-sensing coils and safety gratings to sense vehicles and trigger the millimeter-wave radar.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-2 The present invention provides a technical solution for a parking and reversing detection device during the green pass vehicle inspection process on a highway: a parking and reversing detection device during the green pass vehicle inspection process on a highway, comprising symmetrically distributed safety islands 1, a green pass detection channel formed between two safety islands 1, and also comprising an X-ray transmitting cabinet 2 and an X-ray receiving cabinet 3 symmetrically distributed on the two safety islands 1 near the entrance of the green pass detection channel, an X-ray transmitter being provided at the upper end of the X-ray transmitting cabinet 2, and an X-ray receiver corresponding to the X-ray transmitter being provided at the lower end of the X-ray receiving cabinet 3, X-ray scanning can be used to scan and image vehicles entering the green pass detection channel, and the image formed by the scan can reflect the cargo loading situation of the vehicle, so that the inspectors can judge whether the loaded cargo is in compliance with regulations.

[0019] A grating transmitting end 4 and a grating receiving end 5 are respectively provided on the two safety islands 1 near the X-ray transmitting cabinet 2 and the X-ray receiving cabinet 3. The grating transmitting end 4 and the grating receiving end 5 are combined to form a safety grating. The safety grating can sense whether a vehicle enters or passes through the scanning range. In conjunction with the application of the ground sensing coil 10, it can monitor when the vehicle enters the green pass detection channel entrance and reaches the detection position, thereby facilitating the transmission of signals to the external control system to control the opening or closing of the millimeter wave radar 8;

[0020] One of the safety islands 1 is also provided with a license plate recognition camera 6, a toll booth 11 and a release barrier 9 in sequence. The license plate recognition camera 6 is fixed to one of the safety islands 1 by an adjustable support rod, and the shooting angle of the license plate recognition camera 6 corresponds to the entrance of the green pass detection channel. Ground sensing coils 10 are provided at the entrance and exit of the green pass detection channel. The ground sensing coil 10 at the entrance of the green pass detection channel is located on the ground between the grating transmitting end 4 and the grating receiving end 5, and the ground sensing coil 10 at the exit of the green pass detection channel is located on the ground on one side of the release barrier 9. When a vehicle enters the green pass detection channel, the ground sensing coil 10 at the entrance of the green pass detection channel is used to sense the vehicle and transmit a signal to the external control system, which is convenient for controlling the millimeter wave radar 8 to start working, and the millimeter wave radar 8 is used to scan and detect the vehicle to determine the speed of the vehicle in the green pass detection channel, thereby determining whether the vehicle is in a parking or reversing state, until the vehicle drives out of the scanning range of the millimeter wave radar 8 or the rear of the vehicle drives out of the X-ray transmitter cabinet 2;

[0021] It also includes a mounting bracket 7 installed on the ceiling just above the exit of the green pass detection channel. A millimeter-wave radar 8 facing the entrance of the green pass detection channel is installed on the mounting bracket 7. The millimeter-wave radar 8 is movably fixed to the mounting bracket 7 through a connecting seat. The millimeter-wave radar 8 is tilted and faces the entrance of the green pass detection channel, so that it is convenient to better detect vehicles entering the green pass detection channel. Moreover, the millimeter-wave radar 8 can be easily disassembled and repaired through the mounting bracket 7, and the operation is convenient.

[0022] The working principle of the present invention is as follows: during operation, a vehicle enters the green pass detection channel entrance. When the front of the vehicle reaches the ground sensing coil 10 at the green pass detection channel entrance, the ground sensing coil 10 receives an induction signal and transmits the signal to an external control system, thereby using the control system to control the millimeter wave radar 8 to start working, and use the millimeter wave radar 8 to scan and detect the vehicle to determine the vehicle speed in the green pass detection channel. When the vehicle speed is normal, a signal is transmitted to the control system, and the control system controls the X-ray emitter to work, so as to perform scanning and imaging operations on the vehicle.

[0023] When the vehicle speed is lower than the minimum speed allowed, it is considered that the vehicle is in a parked state. When the vehicle is parked or reversing, the signal detected by the millimeter-wave radar 8 will be transmitted to the control system, and the control system will automatically stop the X-ray emitter and end the scanning detection.

[0024] When the rear end of the vehicle drives out of the ground sensor coil 10 at the entrance of the green pass detection channel and the safety grating formed between the grating transmitting end 4 and the grating receiving end 5 cannot detect the vehicle, a signal will be transmitted to the control system, and the control system will control the X-ray emitter to stop working and end this scanning detection.

[0025] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
