[0045] The present application will be further described in detail through specific embodiments combined with the drawings.

[0046] As shown in Figure 1 , Figure 3 and Figure 4 , the application provides a parking space ground lock control device, which comprises a base 1, a driving assembly 2 and a control assembly (not shown in the figure).

[0047] The base 1 is fixedly installed at the tail side position of the monitored parking space, which can ensure accurate recognition of the license plate and will not affect the normal entry and exit of the vehicle. The entrance side is not suitable for installation because it needs to ensure vehicle passage, and the two side positions may lead to license plate recognition failure due to the problem of viewing angle.

[0048] The driving assembly 2 comprises a driving motor 21, a rotating disc 22 and a traction member 23. The driving motor 21 is fixed inside the base 1, and its output shaft is drivingly connected with the rotating disc 22. The traction member 23 is made of high-strength steel wire or chain, one end of which is wound in the groove of the rotating disc 22, and the other end is connected to the parking space ground lock 7. When the driving motor 21 is powered on and operates, it drives the rotating disc 22 to rotate and wind the traction member 23, thereby exerting a pulling force to make the baffle 73 change from the horizontal state to the vertical and upright state.

[0049] The control assembly is installed on the base 1 and is in signal connection with the driving motor 21; the control assembly 3 is internally provided with a logic processing unit and can adjust the start-stop, steering and rotating speed parameters of the driving motor 21 in real time according to the license plate recognition signal or the remote control instruction, so as to ensure the accuracy and reliability of the action of the baffle 73.

[0050] The parking space ground lock control device of the application can realize automatic opening or closing of the parking space ground lock, and can improve the use experience of the user.

[0051] As shown in Figure 1 , Figure 3 and Figure 4 , in one specific embodiment of the application, the parking space ground lock control device is provided with a first detection assembly 3 for monitoring the rotating state of the rotating disc 22. The first detection assembly 3 comprises a grating disc 31 and a photoelectric switch 32, wherein the grating disc 31 is coaxially fixed to the end face of the rotating disc 22 and rotates synchronously with the rotating disc 22; the photoelectric switch 32 is fixedly installed at a predetermined position of the base 1 and is in signal connection with the control assembly. The photoelectric switch 32 adopts a groove type structure, and the U-shaped groove is provided with a light emitting end and a light receiving end opposite to each other, and the disc body part of the grating disc 31 is embedded in the U-shaped groove. A plurality of light transmission holes are uniformly arranged in the circumferential direction of the grating disc 31, and the spacing between adjacent light transmission holes is matched with the detection accuracy of the photoelectric switch 32. When the rotating disc 22 drives the grating disc 31 to rotate, the light transmission holes pass through the detection area of the photoelectric switch 32 in sequence, generating a periodic pulse signal.

[0052] In the normal working state, when the baffle 73 of the parking space ground lock 7 is in the upright locked position, if the baffle 73 is pushed down due to external force impact, the falling action of the baffle 73 will be transmitted to the rotating disc 22 through the traction member 23, forcing the rotating disc 22 to rotate in the opposite direction. At this time, the grating disc 31 fixed on the rotating disc 22 rotates with it, and the photoelectric switch 32 can accurately identify the rotating direction of the rotating disc 22 by detecting the passing order of the light transmission holes. When the control assembly receives the reverse rotation signal detected by the photoelectric switch 32, it immediately sends a control instruction to the driving motor 21, and the driving motor 21 starts and drives the rotating disc 22 to rotate in the positive direction, and the baffle 73 is pulled back to the upright position through the traction member 23, thereby realizing the automatic protection function against malicious damage.

[0053] As shown in Figure 1 , Figure 3 and Figure 4As shown in the drawings, in one embodiment of the present application, the first detection assembly 3 is provided with at least two photoelectric switches 32, each of which is installed at a predetermined interval angle along the circumferential direction of the grating disc 31. When the grating disc 31 rotates with the rotating disc 22, each photoelectric switch 32 will detect the passing of the light transmission hole in turn, generating a sequence of pulse signals with phase difference. This arrangement of multiple photoelectric switches 32 can improve the reliability of the rotation direction detection, that is, even if a single photoelectric switch 32 fails or is disturbed, the system can still accurately determine the actual rotation direction and speed of the rotating disc 22 through the signals of other photoelectric switches 32. By comparing the phase relationship of the pulse signals output by each photoelectric switch 32 in real time, the control assembly can eliminate the misjudgment caused by vibration or external light interference, ensuring the accuracy of the abnormal state detection of the baffle 73.

[0054] As shown in the drawings, Figure 1 , Figure 3 and Figure 4 , in one embodiment of the present application, the parking space lock control device is further provided with a second detection assembly 4 for monitoring the rotation state of the drive motor 21. The second detection assembly 4 includes a magnetic member 41 and a Hall sensor 42, wherein the magnetic member 41 is installed on the output shaft of the drive motor 21 and rotates synchronously with the motor shaft; the Hall sensor 42 is installed at a predetermined position of the base 1, its sensing surface maintains appropriate distance with the rotation track of the magnetic member 41, and is electrically connected with the control assembly.

[0055] When the system is in normal working state, if the baffle 73 of the parking space lock 7 is impacted by external force at the upright locking position, the dumping action of the baffle 73 will be transmitted to the rotating disc 22 through the traction member 23, and then drive the output shaft of the drive motor 21 to produce reverse rotation. At this time, the magnetic member 41 fixed on the rotating shaft rotates with the output shaft, and when its magnetic pole passes through the detection area of the Hall sensor 42, the Hall sensor 42 will produce corresponding change of electric signal. The control assembly can accurately determine the rotation direction of the output shaft of the drive motor 21 by analyzing the signal waveform characteristics output by the Hall sensor 42 in real time. When the reverse rotation signal of the rotating shaft is detected, the control assembly immediately sends a start instruction to the drive motor 21, and the drive motor 21 drives the rotating disc 22 to rotate forward immediately, and through the traction of the traction member 23, the baffle 73 is restored to the upright locking position, thereby realizing the automatic compensation function of abnormal external force.

[0056] As shown in the drawings, Figure 1 , Figure 3 and Figure 4As shown, in one specific embodiment of this application, the drive motor 21 includes a synchronously rotating drive shaft and a tail shaft. The drive shaft is located at the front end of the drive motor 21 and is directly connected to the turntable 22 to transmit torque; the tail shaft is located at the rear end of the drive motor 21 and is axially positioned via a tail shaft mounting base 43. The magnetic component 41 is a permanent magnet, which is fixedly mounted on the tail shaft mounting base 43 by interference fit or bonding, and rotates synchronously with the tail shaft. The second detection component 4 can accurately reflect the actual rotation state of the drive motor 21, while avoiding the possible impact on the main transmission system that might occur from installing detection elements on the drive shaft. The installation position of the Hall sensor 42 corresponds to the rotation trajectory of the magnetic component 41, and the air gap distance between them is controlled within the range of 3-5mm to ensure the stability and reliability of the detection signal.

[0057] like Figure 1 , Figure 3 and Figure 4 As shown in one specific embodiment of this application, the second detection component 4 is equipped with at least two Hall sensors 42, which are arranged at predetermined angular intervals along the rotational circumference of the magnetic component 41. Each Hall sensor 42 uses the same packaging specification, its sensing surface is parallel to the rotational plane of the magnetic component 41, and maintains a constant detection distance from the surface of the magnetic component 41. The mounting positions of the multiple Hall sensors 42 are precisely calculated to create a fixed phase difference between their output signals. When the magnetic component 41 rotates with the tail shaft, each Hall sensor 42 sequentially detects the change in the magnetic field of the magnetic component 41, generating pulse signals with timing differences. This arrangement of multiple Hall sensors 42 improves the reliability of rotation direction detection. By comparing the phase relationship of the output signals of each sensor, the control component can accurately determine the actual rotation direction of the drive motor 21, effectively avoiding misjudgments caused by single sensor failure or electromagnetic interference. Simultaneously, the redundant design of multiple Hall sensors 42 also improves the system's fault tolerance, ensuring that normal detection functions are maintained even when some sensors fail.

[0058] like Figure 1 and Figure 2 As shown, in one specific embodiment of this application, the parking space lock control device further integrates a monitor 5, which is installed at a preset position on the base 1 and establishes a communication connection with the control component. The monitor 5 employs a high-definition camera module, with its optical lens facing the vehicle parking area of ​​the monitored parking space. It features autofocus and wide dynamic range, enabling it to clearly capture the license plate information of parked vehicles under different lighting conditions. The monitor 5 uses a video analysis algorithm to identify license plate features in real time and transmits the identification results to the control component for processing. Based on the license plate information provided by the monitor 5 and combined with a preset authorized vehicle database, the control component determines whether the current vehicle has usage rights, thereby deciding whether to control the drive component 2 to perform the opening or closing operation of the parking lock.

[0059] As shown in Figure 1 and Figure 2 In one specific embodiment of the present application, the parking space ground lock control device is further provided with an illuminating lamp 6, the irradiation direction of which is kept synchronous with the view direction of the monitor 5. The illuminating lamp 6 adopts an LED light source module, has adjustable light intensity and color temperature parameters, and realizes intelligent light adjustment function through a control assembly. The illuminating lamp 6 is electrically connected with the control assembly, can automatically adjust output brightness according to ambient light intensity, and ensures to provide suitable license plate illumination conditions for the monitored parking space in different time periods. When the monitor 5 performs license plate recognition, the control assembly synchronously starts the illuminating lamp 6, provides stable auxiliary light source for image acquisition, and thus improves license plate recognition accuracy and system working reliability.

[0060] As shown in Figure 1 The present application also provides a parking space ground lock system, which comprises the parking space ground lock 7 and the parking space ground lock control device in the above-mentioned embodiments, and thus has the advantages of the parking space ground lock control device in the above-mentioned embodiments.

[0061] As shown in Figure 5 In one specific embodiment of the present application, the parking space ground lock 7 comprises a lock seat 71, a lock shaft 72 and a baffle 73. The lock seat 71 is installed on the monitored parking space, so as to prevent the parking space ground lock 7 from being moved.

[0062] The lock shaft 72 is rotatably connected with the lock seat 71, and the baffle 73 is connected with the lock shaft 72. One end of the traction member 23 of the parking space ground lock control device is connected with the lock shaft 72, so as to drive the lock shaft 72 to rotate, and thus drive the baffle 73 to stand on the lock seat 71, so as to realize parking space locking.

[0063] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
