Description

Technical Field

[0001] The utility model relates to the technical field of axle identifiers, in particular to a vehicle axle identification device. Background Art

[0002] Overloading of trucks is a major hidden danger to road traffic safety. With the rapid development of information technology in recent years, scientific and technological control has become an important means of controlling overloading, among which the interconnected supervision of overloading information at the source of freight transportation has become an important direction. Overloading work not only needs to be managed from the road surface, but more importantly, it is necessary to control overloading from the source. Overloading source enterprises include sand and gravel bases, mining sites, brick factories, cement factories, large logistics parks, concrete mixing plants, etc. County (city) level overloading control centers collect data from electronic truck scales installed in source enterprises to carry out overloading control management.

[0003] The electronic truck scale used for overload control data collection, in addition to the traditional floor scale, also includes license plate recognition equipment, vehicle axle recognition equipment, etc. After obtaining the vehicle axle information and loading information, weighing is used to determine whether the vehicle is overloaded.

[0004] For vehicle axle identification devices, traditional axle identifiers mainly include rubber strip axle identifiers, contact axle identifiers, and piezoelectric axle identifiers. When using these traditional axle identifiers, they all require excavation of the foundation and burying of equipment, and either the initial equipment cost is high and the later maintenance is less, or the initial equipment cost is low, but the later maintenance cost is high and difficult. With the development of technology, emerging axle identifiers can better overcome the defects of traditional axle identifiers, without the need for excavation of the foundation, and the equipment investment cost and maintenance cost are significantly reduced, and support video traceability function.

[0005] However, at the same time, the existing AI axle identifiers are mainly installed on the side of the scale, and the truck is photographed from the side, and the number of vehicle axles is identified through the AI ​​image recognition system. However, the existing AI axle identifiers are all shot at a fixed angle, and there are many types of trucks, and the length and width of the vehicle body vary greatly. In addition, the size and width of the tires matched with the vehicle body also vary significantly. Fixed-angle shooting is not conducive to accurately collecting image information of the truck, which affects the recognition result. For this reason, we propose a vehicle axle recognition device. Utility Model Content

[0006] The utility model aims to solve the problem that the existing AI wheel axle identifier has fixed-angle shooting and a single shooting angle, and proposes a vehicle wheel axle identification device.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A vehicle axle identification device comprises a linear motion mechanism, a swing mechanism and an axle identifier installed on one side of a detection channel, wherein the moving direction of the linear motion mechanism is perpendicular to the entry and exit direction of the detection channel, a swing mechanism is arranged on the linear motion mechanism, the swing mechanism is swingably installed on the linear motion mechanism, the swing mechanism swings cyclically from the entrance to the exit direction of the detection channel, and the axle identifier is fixedly installed on the swing mechanism.

[0009] Furthermore, the linear motion mechanism includes a track and an electric track vehicle, the track is laid along a direction perpendicular to the inlet and outlet direction of the detection channel, an electric track vehicle is arranged on the track, and the swing mechanism is rotatably mounted on the electric track vehicle.

[0010] Furthermore, the swing mechanism includes a disc, a rotating shaft, and a crank rocker structure. A mounting groove is provided in the middle of the bottom of the disc, a rotating shaft is provided in the middle of the mounting groove, the disc is rotationally connected to the electric rail vehicle via the rotating shaft, and a crank rocker structure is provided on one side of the rotating shaft to drive the rotating shaft to swing.

[0011] Furthermore, the crank rocker structure includes a pin, a first connecting rod, a second connecting rod, and a motor. A pin fixedly connected to a disc is provided on one side of the rotating shaft. One end of the first connecting rod is hinged to the pin, and the other end is hinged to the second connecting rod. An end of the second connecting rod away from the first connecting rod is fixedly connected to the working end of the motor.

[0012] Furthermore, it also includes a towline cable, which is electrically connected to the linear motion mechanism, the swing mechanism, and the axle identifier.

[0013] Furthermore, the towed cable includes a suspension rope, a slip ring, a cable, a first support rod, and a second support rod. The first support rod is fixedly mounted on a linear motion mechanism, and the second support rod is mounted on one side of the linear motion mechanism. A suspension rope is connected between the two second support rods. A plurality of slip rings are slidably arranged on the suspension rope, and the cable is slidably suspended on the suspension rope through the slip rings.

[0014] Compared with the prior art, the utility model provides a vehicle axle identification device, which has the following beneficial effects:

[0015] The utility model discloses a vehicle axle recognition device. When a truck enters a detection channel from an entrance, the shooting angle of an AI identifier is adjusted according to the vehicle model. At the same time, a linear moving mechanism is used to adjust the vertical distance between the AI ​​identifier and the detection channel so that the shooting angle is adapted to the shooting distance. The utility model is applicable to the axle recognition operation of trucks of different models. When shooting, the axle identifier shoots from the front side of the truck for the first time to identify the axle and single or double tires. When the truck leaves the detection channel, the swing mechanism drives the axle identifier to shoot from the rear side of the truck for the second time. The staff only needs to compare whether the two recognition results are consistent. Compared with the prior art, the truck is shot from an oblique angle, the shooting angle of the axle identifier is increased, the image data used to identify the axle is increased, and the recognition rate is improved.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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 of the embodiments.

[0025] Reference Figure 1-5 The utility model discloses a vehicle axle identification device, comprising a linear moving mechanism 1, a swinging mechanism 2 and an axle identifier 3 installed on one side of a detection channel 5. The moving direction of the linear moving mechanism 1 is perpendicular to the entry and exit direction of the detection channel 5. The linear moving mechanism 1 is installed with a swinging mechanism 2, which is swingably installed on the linear moving mechanism 1. The swinging mechanism 2 swings cyclically from the entrance to the exit direction of the detection channel 5, and the axle identifier 3 is fixedly installed on the swinging mechanism 2.

[0026] The axle identifier 3 can use the AI ​​axle identification system of Hubei Kerr Software Development Co., Ltd. The AI ​​axle identification system includes an axle identifier body and an AI axle identification host. The axle identifier body is installed on the swing mechanism 2. The axle identifier body captures and collects data and sends it to the AI ​​axle identification host for calculation and identification.

[0027] like Figure 1 In the vehicle, the detection channel 5 enters in the direction of the arrow and then exits. When the truck travels near the entrance, the shooting angle and position of the axle identifier 3 are adjusted according to the size of the vehicle.

[0028] In the present application, the shooting angle of the axle identifier 3 refers to the angle between the axle identifier 3 and the entry and exit direction of the detection channel 5. When the angle is 0, the shooting direction of the axle identifier 3 is parallel to the entry and exit direction of the detection channel 5. The smaller the angle, the longer and taller the truck can be photographed by the axle identifier 3, and the easier it is to identify single or double tires with the content of the captured image. The larger the angle, the shorter and shorter the truck can be photographed by the axle identifier 3, and the easier it is to identify the number of axles with the content of the captured image.

[0029] At the same time, when the vertical distance between the axle identifier 3 and the detection channel 5 is smaller, shorter and lower trucks can be photographed, and when the vertical distance is larger, longer and taller trucks can be photographed.

[0030] When photographing a small truck, the angle is adjusted to be larger through the swing mechanism 2, and the axle identifier 3 is driven close to the detection channel 5 through the linear moving mechanism 1. When photographing a large truck, the angle is adjusted to be smaller through the swing mechanism 2, and the axle identifier 3 is driven away from the detection channel 5 through the linear moving mechanism 1, so that the axle identifier 3 can photograph different types of trucks from a more suitable angle and position.

[0031] When the truck drives to the entrance of the detection channel 5, the axle identifier 3 takes a picture of the truck from the front side and identifies the number of axles and whether it is an odd or even tire.

[0032] When the truck enters the detection channel 5, the swing mechanism 2 drives the axle identifier 3 to swing in the direction of the truck's exit. When the truck exits the detection channel 5, the axle identifier 3 photographs the truck from the rear side and photographs the truck image again.

[0033] The two recognition results and the captured images are sent to the control terminal. The staff checks and compares the two data and video information through the display of the control terminal to confirm the recognition results.

[0034] The linear moving mechanism 1 includes a track 101 and an electric track car 102. The track 101 is laid in a direction perpendicular to the entry and exit direction of the detection channel 5. The electric track car 102 is installed on the track 101. The swing mechanism 2 is rotatably installed on the electric track car 102. The electric track car 102 travels on the track 101 in a direction approaching or moving away from the detection channel 5, thereby driving the wheel axle identifier 3 to approach or move away from the detection channel 5.

[0035] The swing mechanism 2 includes a disc 201, a rotating shaft 202, and a crank rocker structure. A mounting groove 207 is provided in the middle of the bottom of the disc 201, and a rotating shaft 202 is installed in the middle of the mounting groove 207. The disc 201 is rotationally connected to the electric rail vehicle 102 through the rotating shaft 202. The rotating shaft 202 is fixedly connected to the disc 201, and the rotating shaft 202 is rotationally connected to the electric rail vehicle 102. A crank rocker structure is provided on one side of the rotating shaft 202 to drive the rotating shaft 202 to swing. When the crank rocker structure is in operation, it drives the rotating shaft 202 and the disc 201 to swing at a certain angle at the same time, thereby driving the wheel axle identifier 3 to swing, respectively toward the inlet and outlet of the detection channel 5.

[0036] The crank rocker structure includes a pin 203, a first connecting rod 204, a second connecting rod 205, and a motor 206. A pin 203 fixedly connected to the disc 201 is installed on one side of the rotating shaft 202. One end of the first connecting rod 204 is hinged to the pin 203, and the other end is hinged to the second connecting rod 205. The end of the second connecting rod 205 away from the first connecting rod 204 is fixedly connected to the working end of the motor 206. When the motor 206 rotates, the rotating shaft 202 and the disc 201 are driven to swing in a circle within a certain angle through the first connecting rod 204, the second connecting rod 205, and the pin 203.

[0037] The crank rocker structure in the present application is different from the traditional crank rocker structure in that when the pin 203 swings to the extreme position close to the side of the motor 206, the centers of the rotating shaft 202, the pin 203, the first connecting rod 204, the second connecting rod 205, and the motor 206 (when viewed from a top view) are on the same straight line.

[0038] The device also includes a towline cable 4, which is electrically connected to the linear moving mechanism 1, the swinging mechanism 2, and the axle identifier 3. The linear moving mechanism 1, the swinging mechanism 2, and the axle identifier 3 are connected to the control console and the external power supply through the towline cable 4 to transmit signals and power. Compared with the traditional buried wiring method, it is easy to lay without excavating the foundation, the ground, and the roadbed, and is convenient for later maintenance.

[0039] The towing cable 4 includes a suspension rope 401, a slip ring 402, a cable 403, a first support rod 404, and a second support rod 405. The first support rod 404 is fixedly installed on the electric rail car 102, and the second support rod 405 is installed on the ground on one side of the linear moving mechanism 1. The suspension rope 401 is connected between the two second support rods 405. The extension direction of the suspension rope 401 is the same as the laying direction of the track 101. A plurality of slip rings 402 are slidably installed on the suspension rope 401. The cable 403 is slidably hoisted on the suspension rope 401 through the slip ring 402. The electric rail car 102, the swing mechanism 2, and the axle identifier 3 are connected to external equipment through the cable 403. When the electric rail car 102 drives the swing mechanism 2 and the axle identifier 3 to move, the first support rod 404 drives the cable 403 to extend or contract synchronously.

[0040] Working principle: When in use, the device is arranged on one side of the detection channel 5, the initial position of the axle identifier 3 is toward the entrance of the detection channel 5, and the initial position of the electric rail car 102 is close to the side of the detection channel 5. When a small truck drives to the entrance of the detection channel 5, the starting motor 206 drives the disc 201 to rotate through the crank rocker structure, so that the shooting angle of the axle identifier 3 is increased; when a large truck drives to the entrance of the detection channel 5, the starting electric rail car 102 drives the axle identifier 3 away from the detection channel 5, and at the same time, the starting motor 206 drives the disc 201 to rotate through the crank rocker structure to adjust the axle identifier 3 to a suitable angle, thereby realizing image shooting of different models through different shooting angles, thereby improving the quality of the shooting content.

[0041] When the vehicle exits the detection channel 5, the axle identifier 3 is adjusted to rotate toward the exit of the detection channel 5 for shooting, and the vehicle is photographed from the rear side to obtain the vehicle's axle and single and double tire images for comparison and confirmation by the staff.
