Description

Technical Field

[0001] The present invention relates to the field of intelligent control technology, and more specifically, to a parking lot controller module. Background Art

[0002] With the acceleration of urbanization and the continuous growth of car ownership, parking lots, as an important part of urban transportation infrastructure, have become increasingly prominent in terms of management and safety. In parking lots, traffic congestion often occurs and needs to be cleared and then moved to designated parking spaces. However, the safe parking of vehicles and prevention of damage have also become important issues that need to be solved urgently. Traditional parking lot management models often rely on manual patrols for evacuation and monitoring, but this method has problems such as low efficiency, slow response speed, and easy omissions, making it difficult to effectively prevent vehicles from being damaged.

[0003] In order to improve the management efficiency and safety of parking lots, parking lot control systems based on automation and intelligent technologies have been widely used in recent years. Among them, parking lot controller modules, as the core components of the control system, play a vital role. However, most of the parking lot controller modules on the market currently focus on basic functions such as vehicle entry and exit management and parking space allocation, and relatively few functional designs for preventing vehicle damage.

[0004] However, when a tire of an existing vehicle is deflated due to the vehicle itself or other human factors after it is parked in a parking lot, if the driver drives away without paying attention, the wheel hub will be deformed, thereby causing greater damage to the vehicle, which is likely to cause unnecessary disputes between the parking lot and the driver, and property loss to the driver. Therefore, a parking lot controller module is proposed. Summary of the invention

[0022] Preferably, the towing assembly includes a second slide rail, a slider and an electric push rod. The second slide rail is installed on the outside of the support seat. The slider is slidably installed on the second slide rail, and the slider is connected to the electric push rod.

[0023] Preferably, the tire detection assembly includes an electric push rod 2, a connecting plate, a laser emitter, a CCD and a protective plate.

[0024] Preferably, a lifting opening is provided on the support plate, and the protective plate is slidably connected to the inner wall of the lifting opening.

[0025] Technical effects and advantages of the present invention:

[0026] By extending the second electric push rod, the protective plate can be raised from the lifting port, so that the laser emitter and CCD are lifted above the top plate. The laser emitter emits laser from the bottom of the tire of the gravity sensing plate, and the CCD cooperates to detect the laser position emitted by the laser emitter. When the laser is emitted to the edge of the wheel hub, the extension of the second electric push rod is recorded, so that the tire height at this time can be determined. When the tire height is too low, the driver is directly reminded of the tire deflation of the vehicle through the broadcaster, so that the driver can maintain it in time. Before leaving, the tire height is checked again to avoid tire leakage during parking, which may lead to direct departure without timely discovery, and the wheel hub is deformed without the buffer of the tire, thereby further ensuring the parking safety of the vehicle and reducing the loss of vehicle damage.

[0027] The first motor is operated to rotate the first screw rod, so that the lifting plate can be raised and lowered, so that the first distance measuring component on the first moving mechanism can be adjusted in height. When the first distance measuring component descends to an appropriate position, the distance between the wheels can be detected, and when the first distance measuring component rises to an appropriate position, the vehicle can be monitored.

[0028] The second motor is operated to rotate the second screw rod, so that the slide seat moves under the sliding connection of the first slide rail, so that the horizontal position of the first distance measuring component can be adjusted. When the first distance measuring component moves at the bottom of the first bracket, the distance between the front and rear wheels on the side of the vehicle can be detected. When the first distance measuring component moves at the top of the first bracket, the monitoring range of the side of the vehicle can be improved, thereby avoiding the generation of blind spots in monitoring. Similarly, the second distance measuring component at different heights can also detect the distance between the front wheels of the vehicle and improve the monitoring range of the front and rear directions of the vehicle.

[0029] The distance between the center of the front wheel hub of the vehicle wheel is detected by the laser rangefinder in cooperation with the camera. The first moving mechanism is operated to move the positions of the laser rangefinder and the camera, so that the laser rangefinder detects the distance between the center of the wheel hub of the rear wheel of the vehicle. The distance between the front wheel and the rear wheel at this time can be determined by the moving distance of the first moving mechanism, and the front and rear measurement data of the laser rangefinder can be used to determine whether the vehicle is in a tilted state. If it is in a tilted state, the real distance between the front and rear wheels can be automatically calculated according to the moving data and the two sets of measurement data, thereby improving the accuracy of the distance detection between the front and rear wheels, so as to facilitate subsequent adjustment and positioning. Similarly, when the second distance measuring component measures the distance between the front wheels, it determines by measuring the distance between the inner edges of the front wheels, and can also automatically calculate the real distance between the front wheels in cooperation with the moving data of the second moving mechanism, so that the specific positions of the four wheels can be accurately determined. When monitoring a parked vehicle, after the camera rises to a certain height, the inclination of the camera can be adjusted by extending and retracting the electric telescopic rod, thereby adjusting the monitoring range.

[0030] By setting the support plate, the movable groove can be completely sealed, thereby avoiding cracks, thereby ensuring the flatness of the top of the top plate, avoiding the vehicle tire from sinking, and improving safety. By setting a gravity sensor between the gravity sensing plate and the support seat, it is possible to detect whether the tire is positioned on the gravity sensing plate, thereby improving the positioning accuracy. By setting a universal wheel at the bottom of the support seat, when the position of the support plate is adjusted, the movement is smoother and the movement friction is reduced.

[0031] By cooperating with each two sets of electric push rods, the overall push-pull force of the tire support mechanism can be increased, thereby reducing the push-pull force shared by each electric push rod, thereby increasing the service life of the electric push rod and avoiding deformation. By setting the second slide rail, resistance can be avoided when the four electric push rods are running separately, making the structure more reasonable and moving more convenient.

[0032] By setting up the vehicle type recording module and the storage module, the position of the tire support mechanism can be quickly adjusted when the same vehicle type is docked later, thereby improving the efficiency of vehicle docking. At the same time, it is convenient to query the vehicle monitoring information.

[0033] The use of LoRa wireless communication technology enables long-distance, low-power communication, improves the efficiency and stability of data transmission, reduces system maintenance costs, and can automatically determine vehicle congestion in the parking lot and generate corresponding unblocking plans, effectively improving the efficiency of vehicles entering and exiting the parking lot, reducing the waiting time of car owners, and realizing automated control and intelligent management, reducing the need for manual intervention, reducing labor costs, and improving parking lot management efficiency.

[0047] The LoRa master module sends a data frame to the LoRa slave module of the specified address. The data frame structure includes an address part and a data part. The address part occupies 2 bytes (hexadecimal) and is used to identify the target LoRa slave module. The LoRa slave module is connected to a slave device, and the slave device is a parking space detector.

[0048] It also includes a data processing and feedback mechanism for processing the status information uploaded by the parking detector and controlling the recognition module to perform corresponding operations;

[0049] The identification module includes an identifier 3 and an audible and visual alarm 4. The audible and visual alarm 4 is installed on the identifier 3. The identification module is used to identify the identity of the vehicle;

[0050] The wheelbase detection module is connected to the identification module, and the wheelbase detection module includes a first lifting mechanism 6, a first moving mechanism 7, a first distance measuring component 8, a second lifting mechanism 10, a second moving mechanism 11 and a second distance measuring component 12. The wheelbase detection module is used to detect the distance between vehicle tires, wherein the first lifting mechanism 6 is connected to the first moving mechanism 7, the first moving mechanism 7 is equipped with the first distance measuring component 8, the second lifting mechanism 10 is equipped with the second moving mechanism 11, and the second moving mechanism 11 is equipped with the second distance measuring component 12;

[0051] The control module is connected to the wheelbase detection module, and the control module includes a dragging component 15, the dragging component 15 is connected to the tire support mechanism 13, and the control module is used to adjust the position of the tire support mechanism 13;

[0052] The voice prompt module is connected to the control module. The voice prompt module includes a broadcaster. The broadcaster is installed on one side of the identifier 3. The voice prompt module is used to remind the driver to move the vehicle position.

[0053] The positioning sensing module is connected to the voice prompt module, and the positioning sensing module is used to cooperate with the voice prompt module to sense whether the vehicle moving position is accurate, and the positioning sensing module includes a tire support mechanism 13;

[0054] The tire detection module is connected to the positioning sensing module. The tire detection module is used to detect the height of the vehicle tire in the current state. The tire detection module includes a tire detection component 16 , and the tire detection component 16 is installed on the tire support mechanism 13 .

[0055] When implementing it, Fig. 9 As shown, serial port device 2 is a device connected to the LoRa communication submodule, and uses the LoRa (Long Range) wireless communication module as a communication bridge between the master and slave devices. LoRa technology is very suitable for the transmission of vehicle information in parking lots due to its long-distance and low-power characteristics. The master device sends instructions or data to the slave device through LoRa, and the slave device receives the instructions and performs corresponding operations, or transmits back vehicle status information.

[0056] Modbus communication protocol: On the slave device side, in order to increase the flexibility and scalability of the system, a module supporting the Modbus communication protocol is introduced. Modbus is a communication protocol widely used in the industrial field. By adding address codes, it can realize independent control and management of multiple slave devices, and increase the number of devices under the slave device by up to 255 (FF) times. In this way, the master device can send instructions to specific slave devices through the Modbus protocol to achieve precise control.

[0057] In the module system, the LoRa master device is connected to each slave device wirelessly, and the slave device communicates with the connected parking space detector through the Modbus module. When the master device needs to obtain vehicle information or send a control command, it first sends the command to the target slave device through the LoRa network, and the slave device then forwards the command to the connected device through the Modbus protocol, performs the corresponding operation, and transmits the result back to the slave device through the Modbus protocol, and then the slave device transmits it back to the master device through the LoRa network.

[0058] The module system automatically determines the vehicle congestion in the parking lot and generates corresponding unblocking plans based on the received vehicle information (such as parking space occupancy, vehicle entry and exit records, etc.) through preset algorithms and logic. For example, when parking spaces in a certain area are tight, the system can automatically guide subsequent vehicles to other free areas, thereby effectively alleviating congestion.

[0059] Specifically, when the vehicle parks at the designated parking space, the identification module senses and identifies the vehicle information after the vehicle approaches the parking platform 1, and reminds the vehicle owner to enter the parking platform. After the vehicle enters the parking platform, the wheelbase detection module detects the wheelbase of the vehicle on the parking platform 1. After detecting the wheelbase of the vehicle, the control module adjusts the position of each tire support mechanism 13 according to the vehicle wheelbase data, and then cooperates with the voice prompt module to remind the driver to move the vehicle so that each tire is positioned on the corresponding tire support mechanism 13. After the positioning sensing module senses that each tire is on the tire support mechanism 13, the tire detection module detects the height of each tire. When the tire height is too low, the announcer reminds the driver. When the vehicle tire height meets the requirements, When required, the driver can leave. At the same time, the first distance measuring component 8 and the second distance measuring component 12 are raised to monitor the vehicles on the parking platform 1. When an unidentified person enters the parking platform 1, the sound and light alarm 4 warns to prevent the vehicles on the parking platform 1 from being damaged by human beings. After the driver returns and passes through the identification module for information recognition again, the tire detection module detects the height of each tire of the vehicle again to prevent tire leakage, which causes the driver to drive away directly and cause wheel deformation, thereby avoiding unnecessary damage to the vehicle. In this way, the monitoring and management of the vehicles on the parking platform 1 is improved, and the driver can be reminded of the tire condition of the vehicle in time, ensuring the safety of the vehicle parking and reducing the driver's losses caused by the vehicle itself.

[0060] Specifically, after the vehicle is identified by the identifier 3, it enters the parking platform 1, the first lifting mechanism 6 on the first bracket 5 operates to make the first moving mechanism 7 descend, and at the same time, the first distance measuring component 8 operates to control the descending position height of the first moving mechanism 7, and then the first moving mechanism 7 operates to make the first distance measuring component 8 detect the distance between the front and rear tires on the side of the vehicle, and the second lifting mechanism 10 on the second bracket 9 operates to make the second moving mechanism 11 descend, so that the second distance measuring component 12 descends to an appropriate position, and then the second distance measuring component 12 detects the distance between the two front wheels on the front side of the vehicle, so as to determine the distance between the four wheels, and then, each dragging component 15 cooperates to drag each tire supporting mechanism 13 to a specified position, and the announcer reminds the driver to move the vehicle so that each wheel is positioned to the corresponding On the tire support mechanism 13, after completing the tire positioning, each tire detection component 16 respectively detects and records the tire height at this time, and performs another detection before the vehicle leaves, compares the height difference of the front and rear tires, and determines whether the tire is leaking. By determining that the tire height is too low, the driver can be reminded of the tire leakage information to avoid the driver directly driving away, causing the wheel hub to deform and cause unnecessary losses. In the process of the vehicle being parked on the parking platform 1, the first distance measuring component 8 and the second distance measuring component 12 are respectively lifted to appropriate heights, and the camera angle is adjusted to make the vehicle within the monitoring range to improve the comprehensiveness of vehicle monitoring, and when an unidentified person enters the vicinity of the vehicle on the parking platform 1, the sound and light alarm 4 sounds an alarm to drive away, thereby improving the protection of the vehicle, avoiding human damage to the vehicle, and improving the safety of vehicle parking.

[0061] Four tire support mechanisms 13 are provided, and each tire support mechanism 13 is connected to a towing assembly 15 on four sides, and each towing assembly 15 is commonly connected to a parking platform 1, a mounting groove 14 is provided in the parking platform 1, a top plate 2 is provided at the top of the parking platform 1, and each top plate 2 is provided with a movable groove, and the bottom end of each tire support mechanism 13 is arranged in the mounting groove 14, and the top surface of each tire support mechanism 13 passes through the movable groove and is flush with the top plate 2, and a matching groove is provided at the top of the movable groove.

[0062] In specific implementation, each tire support mechanism 13 is connected to four dragging assemblies 15, and every two dragging assemblies 15 cooperate in pushing and pulling. When two dragging assemblies 15 push and pull the tire support mechanism 13, the other two dragging assemblies 15 play a guiding role. In the process of shifting the tire support mechanism 13, the tire support mechanism 13 is limited by the movable groove, and the matching groove cooperates with the top of the tire support mechanism 13, which can avoid the formation of holes in the top of the top plate 2, thereby preventing the tire from sinking during the movement of the vehicle.

[0063] An identifier 3 is installed on the top plate 2, and an audible and visual alarm 4 is installed on the top of the identifier 3. A first bracket 5 is provided on one side of the identifier 3, and a first lifting mechanism 6, a first moving mechanism 7 and a first ranging component 8 are installed on the first bracket 5. A second bracket 9 is provided on one side of the first bracket 5, and a second lifting mechanism 10, a second moving mechanism 11 and a second ranging component 12 are installed on the second bracket 9.

[0064] In specific implementation, after the vehicle information is identified by the identifier 3, the first lifting mechanism 6, the first moving mechanism 7 and the first distance measuring component 8 on the first bracket 5 cooperate to operate and can detect the distance between the front and rear wheels on the side of the vehicle, and the second lifting mechanism 10, the second moving mechanism 11 and the second distance measuring component 12 on the second bracket 9 can detect the distance between the two tires on the front side of the vehicle, so that with the cooperation of the two distance measuring components, the distance between the vehicle tires can be determined. When the vehicle is parked on the parking platform 1, the two distance measuring components rise and adjust the camera angle, so that the vehicle can be covered within the monitoring range to improve the monitoring of vehicle safety. When an unidentified person approaches the vehicle, the sound and light alarm 4 will be triggered to sound an alarm and drive away in time, thereby improving the safety of vehicle parking and avoiding vehicle losses. When the vehicle is identified by the identifier 3 before leaving, if the identification information is abnormal, the sound and light alarm 4 will sound an alarm.

[0065] The first lifting mechanism 6 and the second lifting mechanism 10 have the same structure. The first lifting mechanism 6 includes a first motor 601, a first screw rod 602, a guide rod 603 and a lifting plate 604. The output end of the first motor 601 is connected to the first screw rod 602, and guide rods 603 are arranged on both sides of the first screw rod 602. The lifting plate 604 is sleeved on the first screw rod 602, and the lifting plate 604 is slidably connected to the guide rod 603.

[0066] During specific implementation, the first motor 601 is operated to rotate the first screw rod 602, so that the lifting plate 604 can be lifted and lowered, so that the first distance measuring component 8 on the first moving mechanism 7 can be adjusted in height. When the first distance measuring component 8 descends to an appropriate position, the distance between the wheels can be detected, and when the first distance measuring component 8 rises to an appropriate position, the vehicle can be monitored.

[0067] The first moving mechanism 7 and the second moving mechanism 11 have the same structure. The first moving mechanism 7 includes a second motor 701, a second screw rod 702, a first slide rail 703 and a slide seat 704. The second motor 701 and the first slide rail 703 are both installed on the lifting plate 604. The output end of the second motor 701 is connected to the second screw rod 702, and the second screw rod 702 is sleeved with a slide seat 704 that is slidably connected to the first slide rail 703.

[0068] In a specific implementation, the second motor 701 is operated to rotate the second screw rod 702, so that the slide seat 704 moves under the sliding connection of the first slide rail 703, so that the horizontal position of the first distance measuring component 8 can be adjusted;

[0069] Specifically, when the first ranging component 8 moves at the bottom of the first bracket 5, it can detect the distance between the front and rear wheels on the side of the vehicle, and when the first ranging component 8 moves at the top of the first bracket 5, it can improve the monitoring range of the side of the vehicle, thereby avoiding the generation of monitoring blind spots. Similarly, the second ranging component 12 at different heights can also detect the distance between the front wheels of the vehicle and improve the monitoring range of the front and rear directions of the vehicle.

[0070] The first distance measuring component 8 and the second distance measuring component 12 have the same structure, wherein the first distance measuring component 8 is used to detect the distance between the front and rear wheels of the vehicle, and the second distance measuring component 12 is used to detect the distance between the two front wheels of the vehicle. The first distance measuring component 8 includes a laser rangefinder 801, a camera 802 and an electric telescopic rod 803, the laser rangefinder 801 is installed on the slide 704, the top end of the camera 802 is movably connected to one end of the electric telescopic rod 803, the other end of the electric telescopic rod 803 is movably connected to the slide 704, and the bottom end of the camera 802 is movably connected to the slide 704.

[0071] In specific implementation, the distance between the center of the front wheel hub of the vehicle wheel is detected by the laser rangefinder 801 in cooperation with the camera 802, and the first moving mechanism 7 is operated to move the positions of the laser rangefinder 801 and the camera 802, so that the laser rangefinder 801 detects the distance between the center of the wheel hub of the rear wheel of the vehicle. The distance between the front wheel and the rear wheel at this time can be determined by the moving distance of the first moving mechanism 7, and the front and rear measurement data of the laser rangefinder 801 can be used to determine whether the vehicle is in a tilted state. If it is in a tilted state, the real distance between the front and rear wheels can be automatically calculated according to the moving data and the two sets of measurement data, thereby improving the accuracy of the distance detection between the front and rear wheels, so as to facilitate the subsequent adjustment and positioning. Similarly, when the second distance measuring component 12 measures the distance between the front wheels, it determines it by measuring the distance between the inner edges of the front wheels, and can also automatically calculate the real distance between the front wheels in cooperation with the moving data of the second moving mechanism 11, so that the specific positions of the four wheels can be accurately determined.

[0072] When monitoring a parked vehicle, after the camera 802 rises to a certain height, the electric telescopic rod 803 can be extended and retracted to adjust the inclination of the camera 802, thereby adjusting the monitoring range.

[0073] The tire support mechanism 13 includes a support plate 1301, a support seat 1302, a gravity sensing plate 1303 and a universal wheel 1304, wherein the universal wheel 1304 is installed at the bottom of the support seat 1302, the support plate 1301 is installed at the top of the support seat 1302, the gravity sensing plate 1303 is installed in the middle of the support plate 1301, and a gravity sensor is arranged between the gravity sensing plate 1303 and the support seat 1302, wherein the support plate 1301 is slidably arranged in the matching groove, and the length and width of the support seat 1302 are smaller than the length and width of the movable groove, while the length and width of the support plate 1301 are larger than the length and width of the movable groove.

[0074] In specific implementation, the setting of the support plate 1301 can ensure that the movable groove can be completely sealed when the support plate 1301 moves in the matching groove, thereby avoiding cracks, thereby ensuring the flatness of the top of the top plate 2, avoiding the vehicle tire from sinking, and improving safety. By setting a gravity sensor between the gravity sensing plate 1303 and the support seat 1302, it is possible to detect whether the tire is positioned on the gravity sensing plate 1303, thereby improving the positioning accuracy. By setting a universal wheel 1304 at the bottom of the support seat 1302, the movement is smoother and the movement friction is reduced when the position of the support plate 1301 is adjusted.

[0075] The dragging assembly 15 includes a second slide rail 1501, a slider 1502 and an electric push rod 1503. The second slide rail 1501 is installed on the outside of the support seat 1302. The slider 1502 is slidably installed on the second slide rail 1501. The slider 1502 is connected to the electric push rod 1503.

[0076] During specific implementation, the electric push rod 1503 is extended and retracted, so that the slider 1502 can pull the second slide rail 1501, thereby moving the position of the tire support mechanism 13, and the cooperation of every two groups of electric push rods 1503 can increase the overall push-pull force of the tire support mechanism 13, thereby reducing the push-pull force shared by each electric push rod 1503, thereby increasing the service life of the electric push rod 1503 and avoiding deformation. The second slide rail 1501 is set to avoid resistance when the four electric push rods 1503 are running separately, making the structure more reasonable and the movement more convenient.

[0077] The tire detection assembly 16 includes an electric push rod 1601, a connecting plate 1602, a laser emitter 1603, a CCD1604 and a protective plate 1605. The electric push rod 1601 is installed on one side of the support seat 1302. The connecting plate 1602 is installed on the telescopic end of the electric push rod 1601. The laser emitter 1603 is installed on the connecting plate 1602. CCD1604 is arranged on one side of the laser emitter 1603. A support block is connected between the connecting plate 1602 and the protective plate 1605. The protective plate 1605 is arranged above the laser emitter 1603 and CCD1604. A lifting port is opened on the support plate 1301, and the protective plate 1605 is slidably connected to the inner wall of the lifting port.

[0078] In specific implementation, the protective plate 1605 can be raised from the lifting port by extending the electric push rod 1601, so that the laser emitter 1603 and the CCD 1604 are lifted above the top plate 2, and the laser emitter 1603 emits laser from the bottom of the tire of the gravity sensing plate 1303, and the CCD 1604 cooperates to detect the laser position emitted by the laser emitter 1603. When the laser is emitted to the edge of the wheel hub, the extension amount of the electric push rod 1601 is recorded, so that the tire height at this time can be determined. When the tire height is too low, the driver is directly notified of the vehicle wheel through the broadcaster. The tire is deflated so that the driver can maintain it in time. Before leaving, the tire height is checked again to avoid tire leakage during parking, which may lead to direct driving away without timely discovery and deformation of the wheel hub without the buffer of the tire, thereby further ensuring the parking safety of the vehicle and reducing the loss of vehicle damage. The protective plate 1605 is slidably matched with the lifting port so that the protective plate 1605 can protect the laser emitter 1603 and CCD1604 at the bottom, thereby increasing the service life of the laser emitter 1603 and CCD1604.

[0079] Specifically, it also includes a vehicle model recording module and a storage module. The vehicle model recording module is used to record the wheelbase information of the vehicle after parking, and the storage module is used to store the information of the vehicle model recording module and the monitoring information of the camera 802, so that when the same vehicle model is parked later, the position of the tire support mechanism 13 can be quickly adjusted to improve the efficiency of vehicle parking. At the same time, it is convenient to query the vehicle monitoring information.
