Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] As Figure 10 shown, the intelligent barrier license plate recognition system is composed of a license plate recognition barrier device, a storage battery, a mains power facility, and an electronic control component;

[0031] The license plate recognition barrier device is composed of a license plate recognition camera, a barrier machine and supporting facilities, all of which are prior arts;

[0032] The storage battery and the electronic control component are installed inside the chassis of the barrier machine;

[0033] Each electrical component of the license plate recognition gate device is supplied through the same main line. This main line is respectively connected to the energy storage battery and the mains electricity through an electronic control component. The electronic control component can switch the power supply line for the license plate recognition gate device. An electricity monitor for monitoring the battery level is configured in the energy storage battery, and the electricity monitor feeds back the monitoring information to the controller. The license plate recognition gate device mainly uses the power of the energy storage battery. When the power of the energy storage battery is insufficient, the electronic control component switches the power supply so that the license plate recognition gate device uses the mains electricity.

[0034] As Figure 1 , Figure 2 , Figure 3 As shown, the electronic control component includes a housing 1. An inner housing 2 is rotatably installed in the housing 1. Four fixed terminals 22 are provided on the inner wall of the housing 1. The four fixed terminals 22 are evenly distributed. Two relatively positioned fixed terminals 22 form a group, and the four fixed terminals 22 form two groups. The two groups of fixed terminals 22 are respectively connected to the positive and negative lines of the energy storage battery and the mains electricity facilities. Two moving terminals 21 are symmetrically provided on the surface of the inner housing 2. The two moving terminals 21 contact a group of fixed terminals 22. The lines of the two moving terminals 21 are led out from the shaft end and connected to the positive and negative lines of the license plate recognition gate device. An axle column 3 is coaxially fixed to the inner housing 2. The driving device includes a rotating housing 31. The rotating housing 31 is rotatably installed on the outside of the axle column 3 through a bearing. A torsion spring is connected between the rotating housing 31 and the axle column 3. A motor 4 is installed on the surface of the housing 1. The output shaft of the motor 4 is fixed with a worm. A worm gear is fixed on the outside of the rotating housing 31. The worm gear is meshed with the worm. The controller is electrically connected to the motor 4;

[0035] As Figure 4 shown, an arc-shaped convex block 32 is fixed on the surface of the axle column 3. Two damping telescopic members 5 are provided on the surface of the housing 1. The two damping telescopic members 5 are distributed at the starting and ending positions of the rotation of the convex block 32;

[0036] As Figure 5 shown, the damping telescopic member 5 has two structures. Structure one: The damping telescopic member 5 includes a cylinder shell 54. The cylinder shell 54 is fixed to the housing 1. A friction disk 55 is elastically slidably arranged in the cylinder shell 54 through a spring. There is friction between the friction disk 55 and the inner wall of the cylinder shell 54. The part of the friction disk 55 that penetrates the cylinder shell 54 is connected with a contact member;

[0037] When the energy storage battery is fully charged, the two moving terminals 21 contact the two fixed terminals 22 connected to the energy storage battery to supply power to the license plate recognition barrier device. When the power monitor detects that the energy storage battery is insufficient, it transmits a signal to the controller, and the controller controls the motor 4 to work, and the rotating shell 31 rotates through the meshing transmission of the worm gear and the worm. Since the protrusion 32 is blocked by the abutment and cannot rotate with the rotating shell 31 in time, the torsion spring accumulates potential, and the elastic force causes the protrusion 32 to squeeze the abutment, so that the friction disk 55 shrinks into the cylindrical shell 54. Due to the friction between the friction disk 55 and the cylindrical shell 54, the shrinkage of the friction disk 55 The contraction has a certain damping property, and the time for the protrusion 32 to pass over the abutment is relatively long. During this process, the moving terminal 21 is still in contact with the fixed terminal 22 of the energy storage battery for electrical conduction. Since there will be a power outage in the subsequent power supply switching process, the controller can control the license plate recognition barrier device to store relevant data and the like during the process of the protrusion 32 passing over the abutment, so as to avoid the problem of data loss caused by power outage to the license plate recognition barrier device. When the friction disk 55 contracts to a certain distance, the protrusion 32 can pass over the abutment, and the elastic force causes the shaft column 3 to rotate rapidly, and the moving terminal 21 contacts the fixed terminal 22 connected to the mains, completing the circuit switching;

[0038] When the energy storage battery is restored, the power supply switching mode is the same as above.

[0039] like Figure 6 As shown, the structure 2 of the damping telescopic member 5: the damping telescopic member 5 includes a sealing shell 56, the sealing shell 56 is fixed to the housing 1, a piston disc 57 is elastically slid in the sealing shell 56 through a spring, a through groove 58 is provided on the surface of the piston disc 57, the sealing shell 56 is filled with damping fluid, and the piston disc 57 slides into the sealing shell 56 and is connected to a part of the sealing shell 56 where an abutment is provided;

[0040] When the bump 32 squeezes the abutment, the piston disc 57 contracts into the sealing shell 56, and the damping fluid in the sealing shell 56 must pass through the through groove 58. Since the through groove 58 has a small conductive area, the damping fluid penetration efficiency is low, and the piston disc 57 slides slowly in the sealing shell 56, forming a damping effect, ensuring that it takes a certain amount of time for the bump 32 to pass over the abutment.

[0041] like Figure 4 , Figure 5 As shown, the abutment member includes a carrier 51 and a roller 53. A slideway 52 is provided on the surface of the carrier 51. The outer end of the slideway 52 is inclined in the opposite direction of the protruding rotation. The shaft end of the roller 53 is inserted into the slideway 52 so that the roller 53 can move along the slideway 52. ​​A spring that abuts against the roller 53 is provided in the slideway 52 so that the roller 53 is kept at the inner end of the slideway 52.

[0042] When the power supply line is switched, the protrusion 32 contacts the roller 53 at the starting point. At this time, the roller 53 is stuck in the inner end of the slide 52 by force, so that the roller 53 and the carrier 51 move as a whole under the extrusion effect. When the protrusion 32 passes over the roller 53 at the starting point and reaches the roller 53 at the end point, the roller 53 at this position is contacted by the protrusion 32 and moves toward the outer end of the slide 52, so that the protrusion 32 can quickly pass over the roller 53 at the end point, ensuring that the moving terminal 21 and the fixed terminal 22 are quickly aligned and contacted after switching.

[0043] like Figure 3 As shown, a telescopic cavity 23 is opened on the surface of the inner shell 2, and the movable terminal 21 is elastically slidably arranged in the telescopic cavity 23 by a spring. The elastic force of the spring causes the movable terminal 21 to press and contact the fixed terminal 22 to ensure stable conduction.

[0044] The power supply circuit of motor 4 is the same as that of the license plate recognition gate equipment. Since the circuit switching work is completed with a delay, when the circuit is switched, the driving work of motor 4 has been completed. Therefore, the subsequent switching action has no effect on the task execution of motor 4, and there is no need to set an independent continuous power supply circuit for motor 4.

[0045] The sources of power for the energy storage battery are as follows:

[0046] like Figure 7 , Figure 8 , Figure 9 As shown, a pressing power generation device is arranged at the ground part of the gate, and the pressing power generation device comprises a sinking shell 6, which is installed on the ground, and a seesaw 7 is placed on the top of the sinking shell 6, one side of the seesaw 7 is rotatably connected with the sinking shell 6, and a spring is connected between the seesaw 7 and the sinking shell 6, so that the other side of the seesaw 7 is tilted and tilted in the direction of vehicle travel, and the tilted seesaw 7 has the function of preventing the vehicle from going in reverse, and a slide plate 9 is slidably arranged in the sinking shell 6, one end of a connecting rod 91 is rotatably connected with the slide plate 9, and the other end of the connecting rod 91 is rotatably connected with the tilted end of the seesaw 7, and a shaft rod 61 is rotatably arranged in the sinking shell 6, a gear is fixed on the surface of the shaft rod 61, and a rack is fixed on the surface of the skateboard 9, and the gear is meshed with the rack, and one end of the shaft rod 61 is connected to the generator 8 through a one-way bearing, and a transmission is arranged between the generator 8 and the shaft rod 61, which is used to increase the speed transmitted to the generator 8, and the output line of the generator 8 is connected to the energy storage battery through a rectifier, a charging controller, a transformer and other components;

[0047] When a vehicle passes through the barrier, the wheels roll over the rocker 7, causing the rocker 7 to swing down, pushing the slide plate 9 to slide through the connecting rod 91, causing the shaft 61 to rotate through the meshing connection of the gear and rack, and the generator 8 is driven to rotate to generate electricity, and the electrical energy is stored in the energy storage battery. Since the shaft 61 and the generator 8 are connected by a one-way bearing, when the vehicle passes, the shaft 61 can rotate quickly, and the rocker 7 can be quickly tilted up due to the elastic force.

[0048] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
