Description

Technical Field

[0001] The invention relates to the field of stereo garage equipment, and in particular to an automatic correction system for a vehicle loading plate. Background Art

[0002] At present, many three-dimensional parking garages need to use car loading plates. The structure of the car loading plate can be roughly referred to in the patent announcement document CN217269176U, which includes two roller assemblies (the figure number in the document is 7), each roller assembly is independently matched with a drive motor, and the drive motor drives the round rollers on the roller assembly to rotate when it is running. However, there is a problem when parking a vehicle on a car loading plate with this structure, that is, the car loading plate with this structure cannot sense whether the vehicle is parked off-center on the car loading plate, nor can it correct the off-center parked vehicle. When the parking posture on the car loading plate is not correct, when the vehicle is lifted or lowered, it will cause the parking equipment and the vehicle to rub and collide. Summary of the invention

[0003] In view of the above problems, the present invention proposes an automatic correction system for a vehicle loading plate. The correction system can detect whether a vehicle is in a skewed state, and after the detection, the skewed vehicle can be corrected.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An automatic correction system for a vehicle-carrying plate comprises a first roller assembly, a second roller assembly, a first drive motor and a second drive motor, wherein the first drive motor cooperates with the first roller assembly, and the second drive motor cooperates with the second roller assembly, and further comprises a collection module, a power module and a control module, photoelectric detection assemblies are arranged on both sides of the first roller assembly, and photoelectric detection assemblies are arranged on both sides of the second roller assembly, the collection module and the power module are both electrically connected to the control module, the collection module is electrically connected to the photoelectric detection assembly, and the power module is electrically connected to the first drive motor and the second drive motor.

[0006] In this vehicle-carrying plate automatic correction system, each vehicle-carrying plate is composed of two roller assemblies (respectively a first roller assembly and a second roller assembly) and two motors (respectively a first drive motor and a second drive motor), the first roller assembly and the second roller assembly are located in the same plane and are distributed in a rectangular shape, photoelectric detection assemblies are arranged on both sides of the first roller assembly, and photoelectric detection assemblies are arranged on both sides of the second roller assembly, so it is equivalent to that photoelectric detection assemblies are arranged at the four corners of each vehicle-carrying plate, so a group of photoelectric detection assemblies are respectively arranged at the four corners of each vehicle-carrying plate, and each group of photoelectric detection assemblies is distributed in columns, so it is equivalent to that four columns of photoelectric detection assemblies are arranged on each vehicle-carrying plate, and the four columns of photoelectric detection assemblies are used to sense the four corners of the vehicle.

[0007] The specific working process of this correction system is as follows. Since the photoelectric detection component has two states, namely, an unblocked state (this state can be indicated by the number 0) and a blocked state (this state can be indicated by the number 1), the detection state of the four columns of photoelectric detection components on each carrier board can be represented by a group of four-digit numbers (the numbers can only be 0 or 1). The control module can determine whether the vehicle is in a skewed state and which direction to change to for correction by analyzing this group of numbers. When the control module determines that the vehicle is parked at the carrier position and needs to be corrected, the power module drives the first drive motor or the second drive motor to operate in the corresponding reverse direction. During the operation, the position of the vehicle on the carrier board can be corrected. After the correction is completed, the correction of the vehicle is completed.

[0008] In summary, this correction system can detect whether a vehicle is in a skewed state, and after the detection, the skewed vehicle can be corrected.

[0009] Optionally, an operation module is also included, and the operation module is connected to the control module.

[0010] The specific operation module may be an operation screen. After the driver has parked the vehicle, the driver may determine the parking completion signal through the operation module, and may also rely on the above operation module to perform the vehicle pickup operation when picking up the vehicle.

[0011] A calibration method applicable to the automatic calibration system as described above comprises the following steps:

[0012] S1 (collection step), the collection module is used to collect the photoelectric signal of the photoelectric detection component and transmit the signal to the control module,

[0013] S2 (analysis step), the control module is used to analyze the photoelectric signal and determine whether the vehicle needs to be corrected and the direction of correction,

[0014] S3 (execution step), when correction is required, the control module sequentially outputs the direction to be corrected and the corresponding motor to the power module. After receiving the instruction, the power module starts to output the action and drives the corresponding motor to run in the corresponding direction.

[0015] In the above steps, the photoelectric signal of the photoelectric detection component is first collected by the module. After the collection is completed, the photoelectric signal is analyzed to determine whether the vehicle is in a skewed state, and the vehicle in a skewed state is immediately corrected by running the corresponding motor.

[0016] Optionally, a recalibration step is also included. After the execution step is completed, the acquisition module continues to collect photoelectric signals and sends them to the control module. The control module analyzes whether the vehicle is in a skewed state based on the new photoelectric signals. If the vehicle is still in a skewed state, a new round of execution steps (ie, S3) is continued.

[0017] Because it may be impossible to completely correct the vehicle after executing one execution step, the vehicle is recalibrated to see if it is in a skewed state after executing one execution step. If the vehicle is still found to be in a skewed state after the recalibration, a new round of execution steps is executed to continue to correct the deviation.

[0018] Optionally, the execution time of a single execution step is set to N. When the controller timing reaches N, the control module immediately issues an alarm message, and the power module immediately controls the motor to stop; when the recalibration step is executed, the timing is reset to zero and restarted.

[0019] In order to prevent the vehicle from scraping the chain or hitting other vehicles due to excessive correction caused by abnormal external signals or the correction action cannot be stopped normally during the correction action, the alarm time of a single execution step is set to N. If the correction action (i.e. execution step) time exceeds N, the control module will issue an alarm signal and the power module will immediately control the motor to stop. The specific value of N can be set as needed.

[0020] Optionally, when the photoelectric signal collected after executing two rounds of execution steps still shows that the vehicle is in a skewed state, the next round of execution steps will not be continued, and the control module will directly issue an alarm message.

[0021] Because this correction method determines whether the vehicle is in a skewed state by whether the photoelectric detection component is covered, but if the vehicle is in an extra-wide state, the photoelectric detection component will always be covered. Therefore, after executing two rounds of execution steps, if the vehicle is still in a skewed state, the vehicle may be in an extra-wide state, so the above method is used to determine whether the vehicle is in an extra-wide state.

[0022] The beneficial effect of the present invention is that the correction system can detect whether the vehicle is in a skewed state, and after the detection, the skewed vehicle can be corrected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] Example 1

[0035] Combined with Figure 1 As shown in, an automatic correction system for a vehicle carrier plate includes a first roller assembly 101, a second roller assembly 102, a first drive motor 201 and a second drive motor 202, the first drive motor 201 is matched with the first roller assembly 101, and the second drive motor 202 is matched with the second roller assembly 102, and also includes a collection module, a power module and a control module. Photoelectric detection components are arranged on both sides of the first roller assembly 101, and photoelectric detection components are arranged on both sides of the second roller assembly 102. The collection module and the power module are both electrically connected to the control module, the collection module is electrically connected to the photoelectric detection component, and the power module is electrically connected to the first drive motor 201 and the second drive motor 202.

[0036] In this vehicle-carrying plate automatic correction system, each vehicle-carrying plate is composed of two roller assemblies (respectively, a first roller assembly 101 and a second roller assembly 102) and two motors (respectively, a first drive motor 201 and a second drive motor 202). The first roller assembly 101 and the second roller assembly 102 are located in the same plane and are distributed in a rectangular shape. Photoelectric detection assemblies are arranged on both sides of the first roller assembly 101, and photoelectric detection assemblies are arranged on both sides of the second roller assembly 102, so it is equivalent to that photoelectric detection assemblies are arranged at the four corners of each vehicle-carrying plate, so a group of photoelectric detection assemblies are respectively arranged at the four corners of each vehicle-carrying plate, and each group of photoelectric detection assemblies is distributed in columns, so it is equivalent to that four columns of photoelectric detection assemblies are arranged on each vehicle-carrying plate, and the four columns of photoelectric detection assemblies are used to sense the four corners of the vehicle.

[0037] The specific working process of this correction system is as follows. Since the photoelectric detection component has two states, namely, an unblocked state (this state can be indicated by the number 0) and a blocked state (this state can be indicated by the number 1), the detection state of the four columns of photoelectric detection components on each vehicle-carrying plate can be represented by a group of four-digit numbers (the numbers can only be 0 or 1). The control module can determine whether the vehicle is in a skewed state and which direction to change to for correction by analyzing this group of numbers. When the control module determines that the vehicle is parked at the vehicle-carrying position and needs to be corrected, the power module drives the first drive motor 201 or the second drive motor 202 to run in the corresponding reverse direction. During the operation, the position of the vehicle on the vehicle-carrying plate can be corrected. After the correction is completed, the correction of the vehicle is completed.

[0038] Combined with Figure 1 As shown in the figure, there are four rows of photoelectric detection components, which are located at the four corners of the vehicle carrier plate, namely the front left photoelectric detection component 311, the front right photoelectric detection component 312, the rear left photoelectric detection component 321 and the rear right photoelectric detection component 322. Each vehicle carrier plate is provided with four groups of photoelectric detection modules.

[0039] In summary, this correction system can detect whether a vehicle is in a skewed state, and after the detection, the skewed vehicle can be corrected.

[0040] It also includes an operating module, which is connected to the control module.

[0041] Example 2

[0042] A calibration method applicable to the automatic calibration system as described above comprises the following steps:

[0043] S1 (collection step), the collection module is used to collect the photoelectric signal of the photoelectric detection component and transmit the signal to the control module,

[0044] S2 (analysis step), the control module is used to analyze the photoelectric signal and determine whether the vehicle needs to be corrected and the direction of correction,

[0045] S3 (execution step), when correction is required, the control module sequentially outputs the direction to be corrected and the corresponding motor to the power module. After receiving the instruction, the power module starts to output the action and drives the corresponding motor to run in the corresponding direction.

[0046] In the above steps, the photoelectric signal of the photoelectric detection component is first collected by the module. After the collection is completed, the photoelectric signal is analyzed to determine whether the vehicle is in a skewed state, and the vehicle in a skewed state is immediately corrected by running the corresponding motor.

[0047] It also includes a recalibration step. After the execution step is completed, the acquisition module continues to collect photoelectric signals and sends them to the control module. The control module analyzes whether the vehicle is in a skewed state based on the new photoelectric signals. If the vehicle is still in a skewed state, a new round of execution steps (ie, S3) is continued.

[0048] Because it may be impossible to completely correct the vehicle after executing one execution step, the vehicle is recalibrated to see if it is in a skewed state after executing one execution step. If the vehicle is still found to be in a skewed state after the recalibration, a new round of execution steps is executed to continue to correct the deviation.

[0049] The execution time of a single execution step is set to N. When the controller timing reaches N, the control module immediately issues an alarm message and the power module immediately controls the motor to stop. When the recalibration step is executed, the timing is reset to zero and restarted.

[0050] In order to prevent the vehicle from scraping the chain or hitting other vehicles due to excessive correction caused by abnormal external signals or the correction action cannot be stopped normally during the correction action, the alarm time of a single execution step is set to N. If the correction action (i.e. execution step) time exceeds N, the control module will issue an alarm signal and the power module will immediately control the motor to stop. The specific value of N can be set as needed.

[0051] If the photoelectric signal collected after executing two rounds of execution steps still shows that the vehicle is in a skewed state, the next round of execution steps will not be continued, and the control module will directly issue an alarm message.

[0052] Because this correction method determines whether the vehicle is in a skewed state by whether the photoelectric detection component is covered, but if the vehicle is in an extra-wide state, the photoelectric detection component will always be covered. Therefore, after executing two rounds of execution steps, if the vehicle is still in a skewed state, the vehicle may be in an extra-wide state, so the above method is used to determine whether the vehicle is in an extra-wide state.

[0053] Example 3

[0054] Combined with Figure 2 To Attachment Figure 4 As shown in , the correction method shown in Example 2 is further described in detail.

[0055] S1, the owner parks the vehicle on the vehicle loading board and confirms the parking is completed on the operation module (i.e., the operation screen). The status of the vehicle at this time is as shown in the following figure. Figure 2 as shown in .

[0056] S2, the acquisition module sends four pairs of photoelectric signals (front left unblocked 0, front right blocked 1, rear left blocked 1, rear right unblocked 0) to the control module. The front left and front right here refer to the wheels of the vehicle.

[0057] S3, the controller receives the photoelectric signal of 0110 and determines that the 2nd and 3rd digits need to be corrected (the 1st digit, 2nd digit, 3rd digit, and 4th digit from right to left)

[0058] The correction rule is: the directions and motors that need to be moved in the 1st, 2nd, 3rd and 4th positions are: the second drive motor moves left, the second drive motor moves right, the first drive motor moves left and the first drive motor moves right.

[0059] It is determined that the vehicle carrier needs to move the first roller assembly to the left and the second roller assembly to the right, and the first drive motor is simultaneously issued an instruction to move the first drive motor to the left and the second drive motor to the right to the power module.

[0060] S4, the power module receives the command and simultaneously executes the first drive motor to move left and the second drive motor to move right. Through the actions of the first roller assembly to move left and the second roller assembly to move right, the front of the vehicle moves to the left and the rear of the vehicle moves to the right. The vehicle rotates clockwise with the center of the vehicle plate as the axis. In order to make the corrected vehicle posture closer to the standard parking posture, the correction action is delayed, that is, after the vehicle leaves the blocked photoelectric, the power module will continue to act for 1S (tentatively 1S, the specific time depends on different types and different motors).

[0061] S5, if after correction, the body posture is overcorrected and deviates from the center line, the posture after correction is as follows Figure 3 , the control module can perform recalibration based on the received four pairs of photoelectric signals (photoelectric signal is 0001). According to the correction rule, the recalibration action is to move the first drive motor to the left. At this time, the delay time of the recheck action is 0.5S (tentatively set to 0.5S, the specific time depends on different types and motors). The final state after the correction is completed is as shown in the attached figure. Figure 4 as shown in .

[0062] To avoid multiple calibrations of the vehicle plate, each vehicle plate is set to be calibrated up to 2 times (including 1 re-inspection action). If the number of calibrations exceeds 2 times, the controller will send out an alarm signal, indicating that the vehicle is abnormal and cannot be parked, and the administrator needs to be contacted for processing.

[0063] The above embodiment is only a schematic diagram of a state where a vehicle carrying plate needs to be corrected after parking.

[0064] Example 4

[0065] This embodiment shows the process of aligning multiple vehicle loading plates after parking. Figure 5 As shown in the Figure 5 There are three vehicle-carrying plates in total, and each vehicle-carrying plate is provided with a correction system as shown in Example 1. Figure 5There are vehicles parked on each vehicle loading plate, and each vehicle on the vehicle loading plate needs to be corrected. The correction order is based on the three groups of photoelectric signals received by the control module, and the order of the vehicle plate number from high to low, that is, the 3rd column, the 2nd column, and the 1st column (see the attached Figure 5 As shown in the figure, the top loading board is the third column, and the bottom loading board is the first column). The corresponding correction direction and action are obtained, and the correction action is performed in sequence. The vehicles on each loading board are corrected according to the method shown in Example 3. When the correction of the loading board in the third column is completed or no correction is required, the four pairs of photoelectric signals in the third group are all (0000). At this time, the controller executes the correction action of the second column, and similarly executes the correction action of the first column. Finally, when the vehicles parked on each loading board have completed the correction, the status of the vehicles on the loading board is as shown in the attached figure. Figure 6 In this embodiment, only three vehicle loading plates are arranged, and in other equivalent embodiments, more vehicle loading plates can be arranged, and the vehicles on each vehicle loading plate are calibrated in turn according to the detailed calibration method shown in Example 3.

[0066] The above-described embodiments only express some embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, it is still possible to modify the technical solutions recorded in the above-mentioned embodiments, or to replace some of the technical features therein with equivalents.
