Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, specifically to a control system applied to a lifting and traversing parking equipment. Background Technology

[0002] Parking equipment is widely used in China, with lift-and-slide parking systems accounting for over 60% of the market share. Lift-and-slide parking systems are simple in design and cost-effective, currently operating in millions of spaces. However, their relatively narrow entrance and exit width has been a persistent drawback. For the past two or three decades, the main structure (especially the control system) of lift-and-slide parking systems has seen little improvement; even when improvements have been made, they have primarily focused on changes in the operator's form factor, such as from mechanical buttons to card swipes and touchscreens. In recent years, some manufacturers have added four sets of drive rollers to all parking platforms for adjusting vehicle position and integrated related electronic control functions into the original control system. This improvement can correct the position of vehicles parked on the platform; however, due to high costs, poor compatibility, and low cost-effectiveness, it has limited appeal to customers. The biggest problem lies in the fact that the friction coefficient of roller-supported vehicles is significantly lower than that of vehicles supported by a flat steel plate, which has a significant impact on the lifting platform. This is because if the platform tilts during lifting, the possibility of vehicle overturning increases significantly, undoubtedly increasing the safety risks of the equipment. Therefore, finding a more effective and lower-cost technical solution has become an urgent problem to be solved in the industry. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology of improving the vehicle platform of the lifting and traversing parking equipment, such as unsatisfactory effect, low cost-effectiveness, poor compatibility, and high safety risks.

[0004] First, let's do a basic analysis:

[0005] The biggest drawback of lift-and-slide parking systems is the narrow width of the entrances and exits, and vehicle positioning cannot effectively solve this problem.

[0006] The characteristic of lift-and-slide parking systems is that the number of lateral parking platforms is far less than the number of lift parking platforms (the ratio of lateral parking platforms to the total number of parking platforms is less than half for two-story buildings, less than one-third for three-story buildings, and so on; while the number of lift parking platforms is the total number of parking platforms minus the number of lateral parking platforms). If vehicle positioning is the sole or primary objective, then all parking platforms indeed need to undergo the same improvements.

[0007] Because the lifting platform has traction chains on both sides in the longitudinal direction, the vehicles parked on the lifting platform are basically already in the center position. Therefore, it is not very meaningful to adjust the vehicle position on the lifting platform. More importantly, installing roller devices on the lifting platform will significantly increase the safety risks of equipment operation.

[0008] Further analysis:

[0009] 1. The key to solving the problem of users having difficulty storing and retrieving vehicles lies in whether the entrance and exit width of the storage and retrieval platform to be operated by the user can be increased without changing the overall width of the equipment. Therefore, the primary objective is to laterally shift vehicles that affect users' storage and retrieval operations and increase the width of the entrance and exit width for users' current entry and exit.

[0010] 2. Since there is at most one lifting platform on the ground floor, it is sufficient to increase the lateral displacement of the vehicle by only moving the platform; moreover, due to the presence of the traction chain, the lateral displacement increase of the lifting platform is not very meaningful.

[0011] 3. It is feasible to install a drive roller device on the vehicle platform to achieve lateral displacement of the vehicle, but only two sets of drive rollers are needed to achieve the relevant functions.

[0012] 4. By adopting appropriate control methods, the lateral displacement of the vehicle can be achieved by setting two sets of drive roller devices on the transverse moving plate.

[0013] 5. The lateral displacement of the vehicle can be operated independently of the vehicle control system. Considering the need to reduce the impact on the original control device and ensure compatibility (especially to facilitate the upgrading and transformation of existing equipment), it would be more reasonable to add a control device specifically designed for the lateral displacement of the vehicle or similar improved functions, while retaining the existing control device.

[0014] 6. It would be more reasonable to change the operator from a subordinate position in the control system to a command center position in the control system.

[0015] Based on the above analysis, the specific technical solution of the parking equipment control system of this utility model is as follows:

[0016] A parking equipment control system, characterized in that it is applicable to lifting and traversing parking equipment, comprising:

[0017] The first electronic control device includes a first main control unit and a drive device, a detection device, and a warning device that are connected to the first main control unit by line to realize vehicle scheduling.

[0018] The operator includes a keyboard unit and a display unit; the keyboard unit includes a vehicle panel selection key, a parking space selection key, or a license plate selection key.

[0019] The operator is signal-connected to the first main control unit of the first electronic control device.

[0020] The control system further includes:

[0021] The second electronic control device includes a second main control unit and a vehicle position detection component and a vehicle displacement drive component connected to the second main control unit via wiring.

[0022] The vehicle position detection component is set up for each ground parking space to detect the lateral relative position of the vehicle platform currently located in the ground parking space and the vehicles parked on the vehicle platform.

[0023] Each lateral movement platform is equipped with one vehicle displacement drive assembly, which drives the displacement of vehicles parked on the lateral movement platform. The displacement drive includes lateral displacement drive and steering displacement drive.

[0024] The operator is signal-connected to the second main control unit of the second electronic control device.

[0025] Furthermore, according to the aforementioned parking equipment control system, the feature is that each of the longitudinal side edges of the transverse moving platform is provided with a set of vehicle lateral displacement over-limit detection units, and the over-limit detection units are signal-connected to the second main control unit.

[0026] When a vehicle parked on the transverse platform moves laterally, if the wheels exceed the preset displacement area, the over-limit detection unit is triggered to send an over-limit signal to the second main control unit, and the second main control unit commands the lateral movement of the vehicle on the transverse platform to stop.

[0027] Preferably, according to the aforementioned parking equipment control system, the over-limit detection unit includes a pressure plate and a position detection element; the pressure plate is disposed on both sides of the longitudinal edge of the transverse vehicle platform at a position away from the lane, and the position detection element is a rocker switch or a position switch, which is installed in conjunction with the pressure plate; when the outer side of the wheel touches the pressure plate, the pressure plate presses the position detection element, and the position detection element sends an over-limit signal.

[0028] Preferably, according to the aforementioned parking equipment control system, the vehicle position detection component includes a camera unit; two camera units are installed in each ground parking space, respectively installed on a frame above the two longitudinal edges of the ground parking space, with the shooting direction facing the longitudinal edges, and the captured image information includes the longitudinal edge of the vehicle platform currently located in the ground parking space and the longitudinal outline of the vehicle parked on the vehicle platform on the same side as the vehicle platform.

[0029] Furthermore, according to the aforementioned parking equipment control system, the feature is that only one set of camera units is installed on the common longitudinal edge line between two adjacent ground parking spaces. The image information captured by the camera unit includes the longitudinal edge lines of the two car platforms currently located in the two adjacent ground parking spaces, and the longitudinal outline of the vehicles parked on the two car platforms on the same side as the car platforms.

[0030] Preferably, according to the aforementioned parking equipment control system, the vehicle displacement drive assembly includes two sets of drive roller units powered by motor reducers and two sets of unpowered follower roller units. The motor reducers are connected to the second main control unit and are controlled by commands from the second main control unit.

[0031] The two sets of drive roller units are respectively arranged at both ends of the longitudinal direction of the transverse platform. The arrangement method includes longitudinal side arrangement or longitudinal diagonal arrangement, with each corresponding to one wheel of the vehicle parked on the transverse platform. The center line of the drive roller of the drive roller unit is parallel to the longitudinal center line of the transverse platform, and the center distance between two adjacent drive rollers is smaller than the width of the vehicle wheel.

[0032] The two sets of follower roller units are respectively set at the longitudinal ends of the transverse car platform where the drive roller unit is not set, and above each of the wheels of the vehicle parked on the transverse car platform; the center line of the follower roller of the follower roller unit is parallel to the longitudinal center line of the transverse car platform, and the center distance between two adjacent follower rollers is smaller than the width of the vehicle wheel.

[0033] The upper surfaces of the drive roller and the follower roller are located on the same horizontal plane.

[0034] The following provides further explanation of some of the statements mentioned above.

[0035] Regarding "drive devices, detection devices, and warning devices required for vehicle dispatching".

[0036] As is known in the industry, the aforementioned drive device, detection device, and warning device include a vehicle platform lateral movement drive unit, a vehicle platform lifting drive unit, a vehicle platform lateral movement position detection unit, a vehicle platform lifting position detection unit, a personnel / vehicle accident detection unit, and an equipment operation warning unit.

[0037] About the operator.

[0038] One of the main functions of the operator is to select the vehicle platform for which a parking or retrieval operation is to be performed. The operator's keyboard unit can be configured with a vehicle platform selection key (usually inputting the vehicle platform number), a parking space selection key (inputting the parking space number or directly selecting a parking space), or a license plate selection key (usually inputting the license plate information on the touch screen). If the parking space selection key or the license plate selection key is used, the operator must correspondingly store a lookup table of the current parking space number and vehicle platform number or a lookup table of the current license plate information and vehicle platform number.

[0039] Regarding the functions and coordination of the operator, the first electronic control device, and the second electronic control device.

[0040] The operator receives the vehicle board selection information from the operator, and the vehicle board is defined as the access vehicle board.

[0041] The first electronic control device has the function of scheduling the position of the storage and retrieval platform.

[0042] The second electronic control device includes lateral displacement of vehicles parked on the transverse moving platform adjacent to the storage and retrieval platform to increase the entrance and exit width of the storage and retrieval platform, and also includes centering displacement of vehicles parked on the storage and retrieval platform.

[0043] The coordination between the operator and the first electronic control device includes:

[0044] If the access platform is a lifting platform and not on the ground floor, the information of the access platform is converted into a platform scheduling command and sent to the first main control unit. The first main control unit implements platform scheduling operation according to the platform scheduling command. The platform scheduling operation includes the access platform descending to the ground floor (with a lateral movement space below the access platform), as well as the lifting platform on the ground floor rising and returning to its original position, the lateral movement platform moving laterally to avoid obstacles, and the access platform descending to the ground floor (with a lateral movement platform below the access platform). After the platform scheduling operation is completed, the relevant information is sent to the operator.

[0045] The cooperation between the operator and the second electronic control device includes:

[0046] If the access platform is a lateral moving platform and a vehicle is parked there, the operator sends a centering displacement command for the vehicle to the second main control unit, and then sends a lateral displacement command to the second main control unit to increase the width of the access platform's entrance and exit. The second main control unit completes the relevant displacement operation according to the centering displacement command and the lateral displacement command. After the operation is completed, the relevant information is sent to the operator.

[0047] If the access platform is a lateral moving platform and there are no parked vehicles, or if the access platform is a lifting platform, the operator sends a lateral displacement command to the second main control unit to increase the width of the access platform's entrance / exit. The second main control unit completes the relevant displacement operation according to the lateral displacement command, and after the operation is completed, the relevant information is sent back to the operator.

[0048] Regarding "increasing the width of the entrance and exit for the storage and retrieval platform":

[0049] First, based on the actual situation of the lifting and lateral moving parking equipment, lifting chains / cables are installed at both the front and rear ends of the longitudinal sides of the lifting platform. Laterally moving vehicles on the lifting platform does not effectively increase the width of the entrance / exit of adjacent platforms. Therefore, the technical solution of this utility model only considers how to achieve lateral movement of vehicles on the lateral moving platform without considering the lifting platform itself.

[0050] Secondly, according to industry practice, lifting and traversing parking equipment uses a reverse parking method. Therefore, when storing and retrieving vehicles on the storage and retrieval platform, the driver's side is fixed. Increasing the width of the entrance and exit should prioritize the driver's side of the storage and retrieval platform, that is, allowing vehicles on the traversing platform adjacent to the driver's side of the storage and retrieval platform to move laterally away from the storage and retrieval platform. However, when the driver's side of the storage and retrieval platform is located at the outermost edge of the equipment, since there is no traversing platform adjacent to the driver's side, lateral movement of vehicles on the driver's side traversing platform cannot be achieved. In this case, lateral movement of vehicles on the non-driver's side traversing platform can be considered, allowing users to enter and exit the cab from the non-driver's side or go around the rear of the vehicle and then enter and exit the equipment's interior area from the non-driver's side.

[0051] Third, lateral displacement of the vehicle is not required in the following situations.

[0052] 1. The ground parking space adjacent to the driver's side of the parking platform is a lateral movement space.

[0053] 2. There are no vehicles parked on the driver's side of the access platform.

[0054] Regarding "centering displacement":

[0055] First, the "centering" refers to aligning the longitudinal centerline of the vehicle with the longitudinal centerline of the corresponding platform. For vehicles parked on the platform, being in a centered position is obviously advantageous for entry and exit.

[0056] Second, the positional deviation of the vehicle on the platform includes angular deviation (the longitudinal centerline of the vehicle is not parallel to the longitudinal centerline of the corresponding platform) and / or lateral deviation (the longitudinal centerline of the vehicle is parallel to but does not coincide with the longitudinal centerline of the corresponding platform). Therefore, the centering displacement includes steering displacement (correcting the deviation that the longitudinal centerline of the vehicle is not parallel to the longitudinal centerline of the corresponding platform) and / or lateral displacement (correcting the deviation that the longitudinal centerline of the vehicle is parallel to but does not coincide with the longitudinal centerline of the corresponding platform), ultimately making the longitudinal centerline of the vehicle coincide with the longitudinal centerline of the corresponding platform.

[0057] It should be noted that the lifting platform of this utility model does not have a lateral displacement function and therefore does not have a centering displacement function. The main considerations are: unlike the platform above which there is no lateral sliding platform to obstruct parking, the lifting platform has lifting chains / cables at both the front and rear ends on both sides of the longitudinal direction. Therefore, vehicles that can be parked smoothly on the lifting platform will not have significant positional deviation. Most importantly, adding a lateral displacement function to the lifting platform would significantly increase safety hazards, which would be counterproductive.

[0058] Regarding the over-limit detection unit.

[0059] The purpose of setting up the over-limit detection unit is to prevent accidents caused by the vehicle moving beyond the limit due to malfunction of the camera unit.

[0060] Regarding the use of the camera unit.

[0061] It is recommended that the photo-taking unit be equipped with a timed detection function triggered by the signal from the vehicle / person entry detection unit, and that the captured image information be sent to the second main control unit. The second main control unit compares the image information before and after to obtain dynamic information on vehicle entry into the platform, vehicle exit from the platform, vehicle door opening, vehicle door closing, personnel entering the platform, and personnel leaving the platform. The dynamic information on the status change is sent to the operator. The operator then determines the usage status of the equipment and the completion status of the user's vehicle storage / retrieval based on this information and provides relevant prompts to the user on the display unit.

[0062] The timed detection function set by the photo-taking unit triggered by the signal of the vehicle / pedestrian trespass detection unit is based on the fact that multiple ground parking spaces share one vehicle / pedestrian trespass detection unit for the lifting and traversing parking equipment. Since it is impossible to determine which ground parking space the user specifically enters, in practical applications, the timed detection of the photo-taking unit triggered by the signal of each vehicle / pedestrian trespass detection unit must detect all ground parking spaces involved in that vehicle / pedestrian trespass detection unit.

[0063] Furthermore, with this technical solution, the completion of a user's parking is marked by the completion of four key actions: vehicle entering the platform, vehicle door opening, vehicle door closing, and personnel leaving the platform. Similarly, the completion of a user's retrieval is marked by the completion of the same four actions. This completely solves the problem that existing technologies have failed to address: how the control system can automatically determine the actual completion of user parking and retrieval. This provides the necessary conditions for further automation improvements to the lifting and traversing parking equipment. The automation functions applied to this technical solution can include: when the control system confirms that the user's operation on the parking platform has been completed, it can perform a centering movement on the vehicle that has already undergone lateral movement.

[0064] Based on the actual situation, the time interval for the above-mentioned timed detection does not need to be too small; it is recommended to be around 1 second.

[0065] Operating modes of the vehicle displacement drive components.

[0066] The operating modes of a vehicle displacement drive assembly based on two sets of drive rollers include the following two.

[0067] The first operating mode includes:

[0068] Lateral displacement operation mode: Two sets of drive roller units drive simultaneously, at the same speed, and in the same direction, so that the vehicle parked on the platform can move laterally.

[0069] Steering displacement operation mode: Two sets of drive roller units drive simultaneously, at the same speed, and in opposite directions, so that the vehicle parked on the platform can perform steering displacement.

[0070] The second operating mode includes:

[0071] Lateral displacement operation mode: Two sets of drive roller units drive simultaneously, at the same speed, and in the same direction, so that the vehicle parked on the platform can move laterally.

[0072] Steering displacement operation mode: One of the two sets of drive roller units acts as the drive unit, while the other acts as the follower unit, so that the vehicle parked on the platform can perform steering displacement.

[0073] This utility model has the following advantages:

[0074] The parking equipment control system provided by this utility model is essentially based on the structure of the operator + control device (defined as the first control device in this utility model) that realizes the basic function of parking space scheduling in the existing control system. It adds a second control device specifically for detecting and controlling the displacement of the vehicle driven on the car platform, and improves the operator to adapt to information interaction with the second control device.

[0075] Compare with the closest existing technology:

[0076] 1. For various improvements and innovations other than parking space scheduling, the technical solution of this utility model only involves adaptive adjustments to the operator and the second control device, resulting in low R&D costs, easy upgrades and replacements, and high flexibility.

[0077] 2. The existing operator is equivalent to a supporting device of the control system. This utility model gives the operator the function of the command center of the control system. The traditional functions involving vehicle scheduling are handed over to the first control device for relevant detection and control, and the functions involving other new functions are handed over to the second control device for relevant detection and control. The structure is simple, clear and reasonable.

[0078] 3. For products from different manufacturers, a second control device and a matching operator can be added while retaining their original operating habits, control systems and control methods, so that the first control device, the second control device and the operator can be standardized and highly compatible.

[0079] 4. For the upgrading of existing equipment, a second control device and matching operator can be added while retaining the original control device and control method, so as to significantly reduce the transformation cost and significantly improve the performance of the original equipment.

[0080] 5. This utility model provides a technical solution with increasing the width of the entrance and exit of the storage and retrieval platform as the primary function and vehicle centering by lateral movement of the platform as an auxiliary function. More improved solutions can be developed with reference to this technical solution.

[0081] 6. The main advantages of the lifting and traversing parking equipment are low manufacturing cost and high cost-effectiveness. Therefore, this invention only requires installing a vehicle traversing drive assembly on the traversing platform and uses only two sets of drive rollers, resulting in low modification costs. Moreover, through optimized settings of relevant components in the control system and the adoption of appropriate control methods, it has the advantages of significantly improved performance and higher cost-effectiveness.

[0082] 7. This utility model can be applied to new products from different manufacturers, as well as to the upgrading and renovation of existing equipment, thus further expanding its scope of application. Attached Figure Description

[0089] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0090] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0091] Figure 1 The diagram shown is a simplified control system structure diagram of the existing technology for lifting and traversing parking equipment.

[0092] As can be seen in the image:

[0093] The operator 1a is connected to the control system 2a by signal. The control system 2a includes a control unit 20a and a vehicle platform lateral movement drive unit 21, a vehicle platform lifting drive unit 22, a vehicle platform lifting position detection unit 23, a vehicle platform lateral movement position detection unit 24, a person / vehicle accidental entry detection unit 25, and an equipment operation warning unit 26, which are connected to the control unit 20a by line.

[0094] As can be seen from the figure, in the prior art, the operator 1a and the control system 2a are relatively independent. The operator 1a sends the user's input information to the control system 2a, which then processes it. The information interaction is unidirectional.

[0095] Figure 2 The diagram shown is a simplified structural diagram of a parking equipment control system according to this utility model.

[0096] As can be seen in the image:

[0097] The control system consists of three parts: an operator 1, a first control device 2, and a second control device 3. The operator 1 is connected to the first main control unit 20 of the first control device 2 and also to the first main control unit 20 of the second control device 3.

[0098] The first control device 2 is equivalent to the control system of the prior art.

[0099] The second control device 3 is a new mechanism compared to the existing technology. The second main control unit 30 (which can be a single-chip microcomputer unit or a PLC unit) is connected to the vehicle displacement drive components 31a, 31b, 32a, 32b, 3Na, and 3Nb of the first and second lateral moving vehicle platforms. It is also connected to the vehicle position detection components 41, 42, and 4M of the ground parking space.

[0100] As mentioned above, each traverse platform requires two sets of drive components to drive the drive roller unit. N traverse platforms require N*2 sets of drive components; each ground parking space requires one set of vehicle position detection components, and M ground parking spaces require M sets of vehicle position detection components.

[0101] The structure of the drive assembly, the structure of the drive roller unit, and the drive of the drive assembly to the drive roller unit are all conventional technologies and will not be described in detail here.
