Description

Technical Field

[0001] The present invention relates to the technical field of over-limit detection, and in particular to a vehicle compartment obstruction over-limit detection device based on laser radar. Background Art

[0002] Overload detection refers to the situation where the vehicle load exceeds the limit imposed by the highway. It mainly studies the relationship between vehicle load and highway, with a special focus on the normal use of highway. At present, vehicles are mainly detected by electronic overload detection. Automatic weighing and image recording equipment installed on important sections of highways are used to automatically detect, shoot and record the gross weight, number of axles, vehicle images and videos of freight vehicles in motion. Laser radar detection systems are used to accurately measure the width and height of vehicles.

[0003] Publication No.: CN214201756U discloses a vehicle over-limit detection device, which is convenient for wiping and cleaning the detection surface of the laser radar sensor by circulating and swinging the cleaning cotton, avoiding unclear detection caused by dust covering the detection surface of the laser radar sensor, and the laser radar sensor can be removed separately, which is convenient for personnel's subsequent maintenance work and meets usage needs.

[0004] However, when the device detects overload on vehicles traveling on county roads or rural roads, it is not convenient to effectively warn and advise the vehicle drivers. County roads and rural roads are mostly small roads with complicated road conditions and many pedestrians. Compared with national roads, provincial roads and expressways, there are fewer speeding and overload devices. Therefore, overload drivers are prone to take chances during driving, and the vehicle speed is much higher than the vehicle speed limit, which can easily cause traffic accidents. Although LED display screens are installed on some roads to warn overload drivers, most drivers do not watch the LED display screens while driving, resulting in the inability to effectively warn and advise the drivers. In addition, watching the LED display screen when the vehicle speed is fast can easily cause traffic accidents.

[0005] Therefore, it is necessary to provide a vehicle compartment occlusion over-limit detection device based on laser radar to solve the above technical problems. Summary of the invention

[0006] The present invention provides a vehicle compartment obstruction over-limit detection device based on laser radar, which solves the technical problem that the existing over-limit detection device in the related art is not convenient for effectively warning and advising the vehicle driver when performing over-limit detection on vehicles traveling on county roads or rural roads.

[0085] In this embodiment, when the drive shaft 86 rotates, it will drive the second half gear 137 to rotate, thereby driving the gear plate 133 and the piston 134 to move downward. Through the tension of the tension spring 132, the gear plate 133 and the piston 134 can be moved upward. Through the up and down reciprocating motion of the piston 134, the air is squeezed and discharged through the buzzer 136, making the buzzer 136 make a sound to warn pedestrians that there is a vehicle approaching from behind, and the sound of the buzzer 136 can disturb birds and prevent them from nesting in the gantry 7, thereby extending the service life of the device.

[0086] Please refer to Figures 1 to 15 The working principle of the vehicle compartment occlusion over-limit detection device based on laser radar provided by the present invention is as follows:

[0087] Step S1, the speed of the moving vehicle is detected by the speed measuring module 1, and the speed data is transmitted to the master control module 5, the master control module 5 analyzes and processes the data, and issues instructions to the electric telescopic rod 103, and the use angle of the laser radar sensor 11 is adjusted by extending or retracting the electric telescopic rod 103 according to the driving speed of the vehicle. When the speed of the moving vehicle is too fast, the electric telescopic rod 103 is extended to drive the adjustment frame 104 to move forward, and the laser radar sensor 11 is driven to flip upward under the action of the rotating member 102.

[0088] After the angle is adjusted, the laser radar sensor 11 can detect the moving vehicle at a farther distance to detect whether the vehicle appearance exceeds the limit;

[0089] Step S2, when the vehicle passes through the quartz weighing sensor and the vehicle detector, the weighing module 2 transmits the data to the master control module 5. After analyzing the data, the master control module 5 determines whether the vehicle is overloaded. When the master control module 5 determines that the vehicle is overloaded, it issues an instruction to the warning module 6. The warning module 6 controls the drive motor 89 to rotate, and issues an instruction to the capture module 4. The camera device 15 and the photographic device 16 are used to record the appearance information of the vehicle, and detect whether the illegal vehicle is blocked, and transmit the detection data to the master control module 5 for storage;

[0090] Step S3, the driving motor 89 rotates to drive the driving shaft 86 to rotate, the driving shaft 86 rotates to drive the first half gear 87 to rotate, the first half gear 87 rotates to drive the rotating shaft 84 to rotate through the first gear 88, the rotating shaft 84 rotates to drive the second bevel gear 85 to rotate, and the rotation of the second bevel gear 85 drives the first bevel gear 82 and the warning sign 81 to rotate, the driving shaft 86 will drive the worm 98 to rotate during the rotation process, and the rotation of the worm 98 will drive the worm wheel 91 to rotate, and the worm wheel 91 will drive the swing plate 95 to swing back and forth through the connecting rod 92 when rotating, and the swing plate 95 drives the swing bracket 96 and the warning rod 97 to swing back and forth through the rotating rod 94, so as to warn and advise the moving vehicle;

[0091] Step S4, when the rotating rod 94 drives the swing bracket 96 and the warning rod 97 to reciprocate left and right, it will also drive the second gear 124 to intermittently reciprocate, and the intermittent reciprocating rotation of the second gear 124 will drive the movable tooth plate 122 and the cleaning block 123 to reciprocate left and right. Through the reciprocating movement of the cleaning block 123, when the laser radar sensor 11 is adjusted to a vertical position by extending the electric telescopic rod 103, the cleaning block 123 can be used to clean the detection surface of the laser radar sensor 11;

[0092] In step S5, when the driving motor 89 drives the driving shaft 86 to rotate, the driving shaft 86 will simultaneously drive the second half gear 137 to rotate. The rotation of the second half gear 137 will drive the gear plate 133 to move downward, so that the guide block 131 slides downward on the inner side of the gantry 7 and the mounting frame 83, and the tension spring 132 is stretched, and the piston 134 slides downward in the sleeve 135. When the second half gear 137 rotates to a certain position and disengages from the gear plate 133, the tension of the tension spring 132 will drive the guide block 131 to slide upward on the inner side of the gantry 7 and the mounting frame 83. When the guide block 131 slides upward, it drives the gear plate 133 to move upward, so that the piston 134 slides upward in the sleeve 135, so that the air is discharged from the buzzer 136, and then the buzzer 136 produces a sound to warn pedestrians.
