Description

[Technical Field]

[0001] An embodiment of the present invention relates to a stopping system for a parking apparatus that parks a vehicle such as an automobile, and also to a parking apparatus equipped with the stopping system. [Background technology]

[0002] A multi-level parking system is known as a vehicle parking system, in which vehicles are placed on pallets and parked in a stacked manner. In this multi-level parking system, the pallets are moved up and down or moved laterally to the left and right, allowing vehicles to enter and exit the parking system from the entrance and exit gate.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-209644 Summary of the Invention [Problem to be solved by the invention]

[0004] In parking systems such as multi-level parking systems, if an abnormal tilt of the pallet is detected, the operation of the parking system is brought to an emergency stop. Because a serious accident, such as a pallet collision, may occur or to prevent a serious accident from occurring, the user cannot release the emergency stop of the parking system. To release the emergency stop of the parking system, the manufacturer or management company of the parking system must be called. However, the pallet may shake significantly due to wind or an earthquake, temporarily detecting an abnormal tilt of the pallet. Even in this case, the abnormal tilt of the pallet is detected, so the operation of the parking system is brought to an emergency stop. Therefore, even if the pallet shaking stops and there is no problem with the parking system (i.e., the pallet is not abnormally tilted), the manufacturer or management company of the parking system must be called to release the emergency stop of the parking system. However, calling the manufacturer or management company to release the emergency stop of the parking system even when no serious accident has occurred increases the burden on the manufacturer or management company. Furthermore, it takes time to release the emergency stop of the parking system, which reduces the convenience of the parking system for users.

[0005] In view of the above-mentioned problems, one embodiment of the present invention aims to provide a parking device stopping system that allows a user to cancel the emergency stop of the parking device when no serious accident has occurred in the parking device that has been emergency stopped. Another embodiment of the present invention aims to provide a parking device equipped with the above-mentioned stopping system. [Means for solving the problem]

[0006] A parking device stopping system according to one embodiment of the present invention is a parking device stopping system that includes multiple parking areas in the vertical and horizontal directions, and in which a pallet on which a vehicle is placed moves between the multiple parking areas. The system includes a tilt sensor that is installed on the pallet and generates information corresponding to the tilt of the pallet, and a control device that sends an emergency stop signal to a control panel of the parking device to stop the operation of the parking device based on the information generated by the tilt sensor. After sending the emergency stop signal, the control device performs a determination at set time intervals as to whether or not a specified condition for using the information is met, and if the number of determinations does not meet the specified condition within a set number of determinations, it sends an emergency stop release signal to the control panel of the parking device to release the emergency stop of the parking device.

[0007] The predetermined condition may be that the control device receives information from a tilt sensor. The information may be an abnormality detection signal generated by the tilt sensor when the tilt sensor detects an abnormality in the tilt of the pallet.

[0008] The predetermined condition may be that the information is equal to or greater than a threshold value. The information may be a detection value obtained by a tilt sensor.

[0009] The set number of determinations may be set in accordance with the stepwise levels determined based on the detection value.

[0010] The set time may be set corresponding to a step level determined based on the detected value.

[0011] The control device may transmit an emergency stop signal when the power to the control panel of the parking device is ON.

[0012] The set number of determinations may be set in accordance with the position of the pallet.

[0013] The set time may be set corresponding to the position of the pallet.

[0014] The parking device stopping system may further include a wind speed sensor that generates a wind speed value, and the set number of determinations may be set based on the wind speed value.

[0015] The parking device stopping system may further include a wind speed sensor that generates a wind speed value, and the set time may be set based on the wind speed value.

[0016] When the control device receives an earthquake early warning, the set number of determinations may be set based on the earthquake early warning.

[0017] When the control device receives an emergency earthquake warning, the set time may be set based on the emergency earthquake warning. [Effects of the Invention]

[0018] According to one embodiment of the present invention, the parking device stopping system allows the user to cancel the emergency stop of a parking device that has been brought to an emergency stop due to, for example, a temporary abnormal tilt of a pallet, even if no serious accident has occurred. This allows the parking device manufacturer or management company to be called only in the event of a serious accident, thereby reducing the burden on the parking device manufacturer or management company and improving the convenience of the parking device for users.

[0020] Hereinafter, each embodiment of the invention disclosed in this application will be described with reference to the drawings. However, the present invention can be embodied in various forms without departing from the spirit of the invention, and should not be construed as being limited to the description of the embodiments exemplified below.

[0021] In order to clarify the description, the drawings may show the width, thickness, shape, etc. of each part schematically compared to the actual embodiment, but these are merely examples and do not limit the interpretation of the present invention. Furthermore, in the specification and drawings, components having the same functions as components explained with reference to previous drawings may be assigned the same reference numerals, and duplicate explanations may be omitted.

[0022] First Embodiment A parking device 10 according to one embodiment of the present invention will be described with reference to FIGS.

[0023] [1. Overview of the configuration of the parking device 10] 1 and 2 are schematic front and side views, respectively, showing the configuration of a parking device 10 according to one embodiment of the present invention. In this specification, the side of the parking device 10 where the entrance and exit gates are located will be referred to as the front, and the opposite side will be referred to as the back. Furthermore, the direction from the front of the parking device 10 to the back, or the direction from the back of the parking device 10 to the front (i.e., the direction in which a vehicle 500 enters and exits the parking device 10) will be referred to as the front-rear direction.

[0024] The parking apparatus 10 has a skeletal structure 100 assembled by support columns 101 and beams 102 erected between the support columns 101. The parking apparatus 10 also has a plurality of areas (hereinafter referred to as "parking areas") partitioned by the support columns 101 or beams 102 so that each vehicle 500 can be accommodated. For example, the parking apparatus 10 shown in FIG. 1 has 16 parking areas: four tiers in the vertical direction (lifting / lowering direction) where the vehicles 500 are stacked, and four rows in the horizontal direction (traverse direction) where the vehicles 500 are arranged side by side. However, the parking apparatus 10 requires spare space for the vehicles 500 to lift, lower, or traverse. Excluding this spare space, as shown in FIG. 1, the parking apparatus 10 can park and accommodate a maximum of 13 vehicles 500. Each tier of the parking apparatus 10 has an entrance / exit for the vehicles 500. That is, a gate 103 is installed on one level of the parking device 10, and the vehicle 500 can enter or leave the parking area by opening or closing the gate 103. The vehicle 500 is placed on a pallet 120 and stored in one of the parking areas.

[0025] The parking device 10 is roughly divided into a parking area located on the first ground level, a parking area located on the second and third intermediate levels, and a parking area located on the fourth uppermost level. A pallet 120 capable of moving laterally left and right is placed in the parking area located on the ground level. A pallet 120 and a traverse carriage 130 are placed in the parking area located on the intermediate level. The traverse carriage 130 is capable of moving laterally and can be coupled to the pallet 120 to move the pallet 120 left and right. A lifting device 121 is also installed on the pallet 120. The lifting device 121 can move the pallet 120 up and down. A pallet 120 with the lifting device 121 installed is placed in the parking area located on the uppermost level, but a traverse carriage 130 is not. Therefore, the pallet 120 placed in the parking area located on the uppermost level can move up and down but cannot move left and right.

[0026] Two pallets 120 adjacent in the left-right direction are arranged with a gap between them so that the vehicles 500 do not interfere with each other. The pallets 120 in the two-tier parking area move laterally from the second tier to the first tier, after the pallets 120 in the first tier parking area located below are moved laterally, allowing the vehicles 500 to enter and leave the parking lot. The pallets 120 in the three-tier parking area move laterally from the third tier to the first tier, after the pallets 120 in the first and second tier parking areas located below are moved laterally, allowing the vehicles 500 to enter and leave the parking lot. The pallets 120 in the four-tier parking area move laterally from the fourth tier to the first tier, after the pallets in the first to third tier parking areas located below are moved laterally.

[0027] The lifting device 121 for the pallets 120 placed in the parking areas located in the middle and top tiers can raise and lower the pallets 120 using suspending chains 122. Four suspending chains 122 installed at four locations on the front, back, left, and right of the pallet 120 are connected to the lifting device 121. However, if the pallet 120 is raised and lowered using only the suspending chains 122, the pallet 120 will sway due to vibrations from the suspending chains 122 or wind, making the lifting and lowering operation of the pallet 120 unstable. For this reason, the parking device 10 has a lifting guide 123 installed on the back side of the pallets 120 placed in the parking areas in the middle and top tiers. Furthermore, the support pillars 101 are provided with guide rails 104 extending in the vertical direction, and the traversing cart 130 is provided with guide rails 131 extending in the vertical direction. The lifting guide 123 of the pallet 120 can engage with the guide rails 104 and the guide rails 131. That is, the lifting guide 123 of the pallet 120 moves along the guide rails 104 and 131, thereby making it possible to stabilize the lifting and lowering operation of the pallet 120.

[0028] The operations of the parking apparatus 10, such as the driving operation of the lifting device 121 accompanying the vertical movement of the pallet 120, the lateral movement of the pallet 120 located on the first level, and the lateral movement of the lateral carriage 130 accompanying the lateral movement of the pallet 120 located on the intermediate level, are controlled based on control signals from a control panel 140. In FIG. 1, the control panel 140 is arranged on the rear side of the parking apparatus 10, but the control panel 140 may also be arranged on the front side of the parking apparatus 10. Meanwhile, a user can operate the operation panel 110 to park or take the vehicle 500 out of the parking apparatus 10. That is, a signal generated by operating the operation panel 110 is transmitted to the control panel 140, and the parking apparatus 10 operates. Here, the operation panel 110 will be described with reference to FIG. 3.

[0029] FIG. 3 is a schematic diagram illustrating the configuration of the operation panel 110 of the parking device 10 according to one embodiment of the present invention.

[0030] As shown in FIG. 3 , the operation panel 110 includes an operation power switch 111, an operation unit 112, an information display unit 113, an information input unit 114, and an emergency stop button 115. The operation power switch 111 is a switch for activating the operation panel 110 of the parking device 10. For example, by inserting an operation key into the operation power switch 111 and turning it from “off” to “on,” the operation panel 110 can be powered on, an operation on the operation unit 112 can be accepted, and / or information can be input using the information input unit 114. The operation unit 112 has an illumination lamp and an operation button for each operation procedure. The information display unit 113 displays various information. The information display unit 113 includes, for example, a display device using a liquid crystal or an OLED. The information input unit 114 accepts information input from a user. The information input unit 114 includes, for example, multiple buttons. The user can operate the multiple buttons on the information input unit 114 to input predetermined information. The emergency stop button 115 is a button that is operated in an emergency. When the emergency stop button 115 is operated, certain operations of the parking device 10 (for example, operations associated with the movement of the pallet 120 or the opening and closing operation of the gate 103) are stopped to ensure the safety of users. The emergency stop of the parking device 10 can be immediately released by operating the operation panel 110 (for example, operating the emergency stop button 115).

[0031] As described above, the parking apparatus 10 is a multi-story parking apparatus capable of parking a plurality of vehicles 500. In a multi-story parking apparatus, when a vehicle 500 parked in two to four levels enters or leaves the parking apparatus, the second to fourth levels of pallets 120 must be moved to the first level. The parking apparatus 10 shown in FIG. 1 uses a system in which the first level of pallet 120 moves laterally and the second to fourth levels of pallets 120 are raised and lowered, but the parking apparatus 10 is not limited to this system. For example, the parking apparatus 10 can use various systems, such as a system in which the first level of pallet 120 is lowered into an underground pit and the second to fourth levels of pallets 120 are lowered to the first level, a system in which the first to third levels of pallets 120 are slid forward and backward and the second to fourth levels of pallets 120 are lowered to the first level, or a combination of these systems.

[0032] Although the parking apparatus 10 shown in FIG. 1 has a four-tier, four-row structure, the structure of the parking apparatus 10 is not limited to this. Depending on the location where the parking apparatus 10 is installed, it may have a structure with fewer than four tiers or five or more tiers in the vertical direction, and may have a structure with fewer than four rows or five or more rows in the horizontal direction. The parking apparatus 10 may have a structure with 1 to m tiers (m is a natural number of 3 or greater) in the vertical direction and 1 to n rows (n is a natural number of 2 or greater) in the horizontal direction (although this specification may refer to the parking apparatus 10 as having m tiers x n rows of parking areas). In this case, the parking area on the first row corresponds to the parking area on the ground level, the parking areas on the second to m-1 rows correspond to the parking areas on the middle rows, and the mth row corresponds to the parking area on the top row. Therefore, in this case, the traverse vehicle 130 is arranged in the parking area located on the second to m-1 rows. Note that a configuration where m=2 can also be applied to parking apparatuses 10 that do not require traverse vehicles.

[0033] Incidentally, pallets 120 may sway due to the influence of wind or earthquakes and tilt significantly. If a significantly tilted pallet 120 moves, there is a risk that the pallet 120 or a vehicle 500 placed on the pallet 120 may collide with the support posts 101, beams 102, or traversing cart 130. For this reason, the parking device 10 is equipped with a stop system 200 that detects abnormal tilt of the pallet 120 and brings the operation of the parking device 10 to an emergency stop. The control configuration of the parking device 10 equipped with the stop system 200 will now be described with reference to FIG. 4.

[0034] 2. Configuration of the Stop System 200 4 is a block diagram illustrating the control configuration of the parking device 10 according to one embodiment of the present invention. As shown in FIG.

[0035] The tilt sensor 210 can detect the tilt of the pallet 120. Specifically, the tilt sensor 210 acquires a detection value corresponding to the tilt of the pallet 120, and generates an abnormality detection signal when the detection value is equal to or greater than a threshold value. The abnormality detection signal generated by the tilt sensor 210 is transmitted to the control device 220.

[0036] The tilt sensor 210 may be installed on each of the multiple pallets 120, or may be installed on some of the multiple pallets 120. For example, as shown in Fig. 2, the tilt sensor 210 is installed on the rear side of the upper surface of the pallet 120, but the installation position of the tilt sensor 210 is not limited to this. The tilt sensor 210 only needs to be installed in a position where it will not be run over by the vehicle 500, and may also be installed on the underside of the pallet 120.

[0037] The control device 220 can execute control processing related to an emergency stop of the parking device 10. The control device 220 may be an IC chip that executes a control sequence, or may be a computer that executes a control program. The control device 220 can execute control processing related to an emergency stop of the parking device 10 by executing the control sequence or the control program. In FIG. 2, the control device 220 is installed separately from the control panel 140. However, the control device 220 may be incorporated into the control panel 140.

[0038] The control device 220 includes a determination unit 221 and a storage unit 222. The determination unit 221 can execute various control processes, including a determination process based on an abnormality detection signal transmitted from the tilt sensor 210. The control processes executed by the determination unit 221 will be described in detail below. The determination unit 221 can also acquire data and information necessary for the control processes. The storage unit 222 can store data or information necessary for the determination processes. For example, the storage unit 222 can store preset thresholds or setting values necessary for the determination processes. The determination unit 221 can execute the determination processes using the thresholds or setting values stored in the storage unit 222.

[0039] The components of the control device 220 are not limited to the determination unit 221 and the storage unit 222. For example, the control device 220 may include a communication unit that receives data or information or transmits data or information.

[0040] Here, the control panel 140 will also be described. The control panel 140 can execute control processing related to the operation of the parking apparatus 10. The control panel 140 may include an IC chip that executes a control sequence, or may include a computer that executes a control program. The control panel 140 can execute control processing related to the operation of the parking apparatus 10 by executing the control sequence or the control program. In FIG. 2, the control panel 140 is installed on the rear side of the parking apparatus 10, but the location of the control panel 140 is not limited to this.

[0041] The control panel 140 includes a control unit 141 and a memory unit 142. The control unit 141 controls the operation of the parking device 10, such as the drive operation of the lifting device 121 accompanying the vertical movement of the pallets 120, the lateral movement of the pallets 120 located on the first level, and the lateral movement of the lateral movement cart 130 accompanying the lateral movement of the pallets 120 located on the intermediate levels. The memory unit 142 can store position information of the pallets 120. Each of the multiple pallets 120 has unique identification information. The pallets 120 move between parking areas, and the control unit 141 can acquire position information of each of the multiple pallets 120 based on the identification information of the pallets 120. The acquired position information of the pallets 120 is stored in the memory unit 142. The memory unit 142 can also store the status (ON or OFF) of the operation power switch 111 acquired from the operation power switch 111 of the operation panel 110. Here, the ON and OFF statuses of the operation power switch 111 correspond to the ON and OFF statuses of the power supply to the operation panel 110, respectively.

[0042] When the control panel 140 receives an emergency stop signal from the stop system 200, it brings the operation of the parking device 10 to an emergency stop. Unlike the emergency stop of the parking device 10, the emergency stop of the parking device 10 cannot, in principle, be released by operating the operation panel 110. For example, when the parking device 10 is in an emergency stop, communication between the control panel 140 and the operation panel 110 is cut off. However, when the control panel 140 receives an emergency stop release signal from the stop system 200, communication between the control panel 140 and the operation panel 110 is reconnected, and it becomes possible to release the emergency stop of the parking device 10 by operating the operation panel 110.

[0043] [3. Control process of the stop system 200] Fig. 5 is a flowchart illustrating the control process of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. As shown in Fig. 5, the control process of the stopping system 200 in this embodiment includes steps S100 to S170. The control process of the stopping system 200 in this embodiment will be described below in accordance with the order of the steps in the flowchart of Fig. 5.

[0044] In step S100, the tilt sensor 210 acquires a detection value corresponding to the tilt of the pallet 120. If the detection value is equal to or greater than a preset threshold, the tilt sensor 210 transmits an abnormality detection signal to the control device 220. The determination unit 221 of the control device 220 determines whether or not the abnormality detection signal has been received. If the abnormality detection signal has been received (step S100: YES), step S110 is executed. If the abnormality detection signal has not been received (step S100: NO), step S100 is executed again. Note that if the detection value is equal to or greater than the threshold, the tilt sensor 210 continues to transmit the abnormality detection signal to the control device 220.

[0045] In step S110, the determination unit 221 transmits an emergency stop signal to the control panel 140. The control unit 141 of the control panel 140 that has received the emergency stop signal stops the operation of the parking device 10 and blocks reception of operation signals from the operation panel 110. As a result, the parking device 10 cannot be operated by the operation panel 110.

[0046] In step S120, the determination unit 221 measures the time t after the parking device 10 is brought to an emergency stop.

[0047] In step S130, the determination unit 221 determines whether the time t is equal to or greater than a preset time T. If the time t is equal to or greater than the set time T (step S130: YES), step S140 is executed. If the time t is less than the set time T (step S130: NO), step S130 is executed again.

[0048] In step S140, the determination unit 221 determines whether or not an abnormality detection signal has been received. If an abnormality detection signal has been received (step S140: YES), step S150 is executed. If an abnormality detection signal has not been received (step S140: NO), step S170 is executed.

[0049] In step S150, the determination unit 221 determines whether the number of determinations n of receiving an abnormality detection signal after an emergency stop of the parking device 10 (i.e., the number of determinations n of determinations made in step S140, where the initial value of the number of determinations is n=1) is equal to or greater than the preset number of determinations N. When the number of determinations n is equal to or greater than the set number of determinations N (step S150: YES), the control process of the stop system 200 ends. When the control process of the stop system 200 ends, the tilt sensor 210 may continue to transmit the abnormality detection signal, or the tilt sensor 210 may be controlled so that the generation of the abnormality detection signal is stopped. On the other hand, when the number of determinations n is less than the set number of determinations N (step S150: NO), step S160 is executed.

[0050] In step S160, the determination unit 221 sets the number of determinations n to n + 1. This makes it possible to count the determinations made in step S140.

[0051] In step S170, the determination unit 221 transmits an emergency stop release signal to the control panel 140. When step S170 is executed, the control processing of the shutdown system 200 ends.

[0052] If step S170 is not executed, i.e., if the number of determinations n is equal to or greater than the set number of determinations N in step S150, the emergency stop of the parking apparatus 10 is maintained. In this case, the abnormal tilt of the pallet 120 is maintained, and there is a high possibility that a serious accident has occurred in the parking apparatus 10. Because communication from the operation panel 110 to the control panel 140 is cut off, the user cannot release the emergency stop of the parking apparatus 10 by operating the operation panel 110. Therefore, in order to release the emergency stop of the parking apparatus 10, it is necessary to call the manufacturer or management company of the parking apparatus 10.

[0053] On the other hand, when step S170 is executed, that is, when the abnormality detection signal is not received within the set number of determinations N when the number of determinations n reaches the set number of determinations N, the control panel 140, which has received the emergency stop release signal generated by the control device 220, releases the emergency stop of the parking device 10. In this case, it is highly likely that no serious incident has occurred in the parking device 10. Therefore, the emergency stop of the parking device 10 is released, and operation of the parking device 10 and operation by the operation panel 110 are enabled. In other words, the parking device 10 is in a stopped state in which it can be operated by the operation panel 110. Therefore, the user can operate the operation panel 110 to resume operation of the parking device.

[0054] With the parking apparatus 10 equipped with the stop system 200 according to this embodiment, if no serious accident has occurred, for example, if the parking apparatus 10 has been brought to an emergency stop due to a temporary abnormal tilt of the pallet 120, the user can cancel the emergency stop of the parking apparatus 10. As a result, if no serious accident has occurred with the parking apparatus 10, there is no need to call the manufacturer or management company of the parking apparatus 10, which reduces the burden on the manufacturer or management company of the parking apparatus. In addition, the convenience of the parking apparatus 10 for users is improved.

[0055] The configuration of the parking device 10 including the stopping system 200 according to this embodiment can be modified in various ways. Below, several modified examples of the parking device 10 will be described with reference to Figs. 6 and 9. In the description of the modified examples, the description of the same configuration as the parking device 10 will be omitted. However, the modified examples of the parking device 10 are not limited to these.

[0056] <Modification 1-1 of the First Embodiment> 6 is a flowchart illustrating the control process of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. The control process of the stopping system 200 shown in FIG. 6 includes step S105 between step S100 and step S110.

[0057] In step S105, the determination unit 221 acquires the status (ON or OFF) of the operation power switch 111 from the memory unit 142 of the control panel 140. When the operation power switch 111 of the operation panel 110 is ON, the user is operating the operation panel 110 and the pallet 120 is moving or is able to move, that is, the parking device 10 is in the activated state. The determination unit 221 determines whether or not the operation power switch 111 is ON. When the operation power switch 111 is ON (step S105), step S110 is executed. When the operation power switch 111 is not ON (step S105), step S100 is executed again.

[0058] In this modified example, when the operation power switch 111 is not ON, i.e., when the operation power switch 111 is OFF, the parking apparatus 10 does not enter an emergency stop state even if there is an abnormality in the tilt of the pallet 120. However, when the user turns the operation power switch 111 ON, the steps from step S110 onwards are executed, and the parking apparatus 10 is brought to an emergency stop. In this modified example, the parking apparatus 10 can be brought to an emergency stop while the user is operating the operation panel 110 of the parking apparatus 10, so the user recognizes that the parking apparatus 10 has been brought to an emergency stop and can call the manufacturer or management company of the parking apparatus 10.

[0059] <Modification 1-2 of the First Embodiment> The tilt sensor 210 may be configured with multiple thresholds, and multiple abnormality detection signals corresponding to the multiple thresholds may be generated. For example, the tilt sensor 210 may be configured with a first threshold and a second threshold greater than the first threshold. In this case, the first abnormality detection signal is generated when the detection value is equal to or greater than the first threshold and less than the second threshold. The second abnormality detection signal is generated when the detection value is equal to or greater than the second threshold. That is, the tilt sensor 210 transmits a first abnormality detection signal to the control device 220 when the pallet 120 exhibits a slight tilt equal to or greater than the first threshold, and transmits a second abnormality detection signal to the control device 220 when the pallet 120 exhibits a serious tilt equal to or greater than the second threshold.

[0060] 7 is a flowchart illustrating the control process of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. The control process of the stopping system 200 shown in FIG. 7 further includes step S108 in the flowchart shown in FIG.

[0061] In step S108, the determination unit 221 of the control device 220 determines whether the received abnormality detection signal is the second abnormality detection signal. If the received abnormality detection signal is the second abnormality detection signal (step S108: YES), step S105 is executed. If the received abnormality detection signal is not the second abnormality detection signal (step S108: NO), step S100 is executed again.

[0062] In the control processing of the stopping system 200 according to this modification, even if the operation power switch 111 is OFF (step S105: NO), when the control device 220 receives a second abnormality detection signal (step S108: YES), an emergency stop signal is sent to the control panel 140 (step S110). That is, according to the control processing of the stopping system 200 according to this modification, even if the operation power switch 111 is OFF, a large tilt of the pallet 120 can be detected and the parking device 10 can be brought to an emergency stop. This makes it possible to prevent a serious accident involving the parking device 10.

[0063] <Modification 1-3 of the First Embodiment> Another modified example will be described in which the tilt sensor 210 generates a plurality of abnormality detection signals (for example, the first abnormality detection signal and the second abnormality detection signal described above).

[0064] 8 is a flowchart illustrating the control process of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. The control process of the stopping system 200 shown in FIG. 8 includes steps S102 and S104 instead of step S100 in the flowchart shown in FIG.

[0065] In step S102, the determination unit 221 determines whether or not a second abnormality detection signal has been received. If the second abnormality detection signal has been received (step S102: YES), step S110 is executed. If the second abnormality detection signal has not been received (step S102: NO), step S104 is executed.

[0066] In step S104, the determination unit 221 determines whether or not a first abnormality detection signal has been received. If the first abnormality detection signal has been received (step S104: YES), step S105 is executed. If the first abnormality detection signal has not been received (step S104: NO), step S102 is executed again.

[0067] In the control processing of the stopping system 200 according to this modification, when the control device 220 receives a second abnormality detection signal (step S102: YES), an emergency stop signal is sent to the control panel 140 regardless of the status of the operation power switch 111 (step S110). Also, when the control device 220 receives a first abnormality detection signal (step S104: YES), an emergency stop signal is sent to the control panel 140 according to the status of the operation power switch 111 (step S110). In other words, according to the control processing of the stopping system 200 according to this modification, even if the operation power switch 111 is OFF, a large tilt of the pallet 120 can be detected and the parking device 10 can be brought to an emergency stop. This makes it possible to prevent a serious accident involving the parking device 10.

[0068] <Modification 2 of the First Embodiment> 9 is a flowchart illustrating the control process of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. The flowchart shown in FIG. 9 includes step S115 between step S110 and step S120.

[0069] In step S115, the determination unit 221 acquires, from the storage unit 142 of the control panel 140, the position information of the pallet 120 on which the tilt sensor 210 that transmits the abnormality detection signal is installed.

[0070] In step S130 of this modified example, a preset time T position can be used. Depending on the position of the pallet 120, the pallet 120 may be prone to shaking and tilting. For example, a pallet 120 located at the top tier may shake more than a pallet 120 located at the ground level, and the shaking time may be longer. Therefore, if the same set time is set for the tilt sensor 210 installed on the pallet 120 located at the top tier and the tilt sensor 210 installed on the pallet 120 located at the ground level, the tilt sensor 210 installed on the pallet 120 located at the top tier will transmit an abnormality detection signal more frequently. Therefore, a set time Tposition is set to adjust the influence of the position of the pallet 120. For example, the set time T position is set to the tilt sensor 210 installed on the pallet 120 located on the ground level. position The time t can be longer than the set time T position If the time t is equal to or greater than the set time T position If it is less than the predetermined value (step S130: NO), step S130 is executed again.

[0071] In step S150 of this modified example, the preset number of determinations is set as a preset number of determinations N depending on the position of the pallet 120. position As described above, the pallet 120 located on the top tier swings more than the pallet 120 located on the ground tier, and the swinging time is longer. position Not only the set number of judgments N position For example, the influence of the position of the pallet 120 may be adjusted by setting the set number of determinations N position is set by the number of determinations N position The number of judgments n can be set to be larger than the number of judgments N position If the number of determinations n is equal to or greater than the set number of determinations N position If it is less than (step S150: NO), step S150 is executed.

[0072] In this modification, the set time T position and the number of set judgments N position By setting the above, the influence of the position of the pallet 120 can be suppressed.

[0073] Second Embodiment A parking device 10 according to one embodiment of the present invention will be described with reference to Figure 10. In the description of this embodiment, the description of the same configuration as the parking device 10 of the first embodiment may be omitted.

[0074] Fig. 10 is a flowchart illustrating the control processing of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. As shown in Fig. 10, the control processing of the stopping system 200 in this embodiment includes steps S200 to S270. Below, the control processing of the stopping system 200 in this embodiment will be described in accordance with the order of the steps in the flowchart in Fig. 10.

[0075] In step S200, the tilt sensor 210 acquires a detection value corresponding to the tilt of the pallet 120 and transmits the acquired detection value to the control device 220. The determination unit 221 of the control device 220 determines whether the detection value is equal to or greater than a preset threshold. If the detection value is equal to or greater than the threshold (step S200: YES), step S210 is executed. If the detection value is less than the threshold (step S200: NO), step S200 is executed again. Note that the tilt sensor 210 continues to transmit the detection value to the control device 220 at all times.

[0076] Steps S210 to S230 are similar to steps S110 to S130 described in the first embodiment, respectively, and therefore will not be described again.

[0077] In step S240, determination unit 221 determines whether the detection value is equal to or greater than the threshold value. If the detection value is equal to or greater than the threshold value (step S240: YES), the control process of stop system 200 ends. If the detection value is less than the threshold value (step S240: NO), step S260 is executed.

[0078] Steps S250 to S270 are similar to steps S150 to S170 described in the first embodiment, respectively, and therefore will not be described again.

[0079] In the parking apparatus 10 equipped with the stopping system 200 according to this embodiment, the control device 220 receives a detection value, rather than an abnormality detection signal, from the tilt sensor 210. The determination unit 221 can make a determination based on the detection value. Therefore, if the parking apparatus 10 has made an emergency stop without a serious accident occurring, the user can cancel the emergency stop of the parking apparatus 10. As a result, if no serious accident has occurred in the parking apparatus 10, there is no need to call the manufacturer or management company of the parking apparatus 10, which reduces the burden on the manufacturer or management company of the parking apparatus. This also improves the convenience of the parking apparatus 10 for users.

[0080] The value transmitted by the tilt sensor 210 to the control device 220 may not be a detected value, but may be a level value obtained by dividing the magnitude of the detected value by the tilt sensor 210. In this case, in step S240, the determination unit 221 of the control device 220 determines whether the level value is a predetermined set level value. If the level value is the set level value (step S240: YES), the control process of the stopping system 200 ends. If the level value is not the set level value (step S240: NO), step S260 is executed.

[0081] The configuration of the parking device 10 including the stopping system 200 according to this embodiment can be modified in various ways. One modified example of the parking device 10 will now be described with reference to FIG. 11. In the description of the modified example, the description of the same configuration as the parking device 10 will be omitted. However, the modified examples of the parking device 10 are not limited to these.

[0082] <Modification of the second embodiment> 11 is a flowchart illustrating the control process of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. The control process of the stopping system 200 shown in FIG. 11 includes step S205 between step S200 and step S210.

[0083] In step S205, the determination unit 221 classifies the magnitude of the detection value in stages and determines the level. The number of levels is not particularly limited. For convenience, the following description will be given assuming that the larger the detection value, the higher the level.

[0084] In step S230 of this modified example, a preset time is set for each level T level The pallet 120 with a large detection value and large vibrations also has a long vibration time. level is set to adjust the effect of the magnitude of shaking of the pallet 120. For example, the set time T level , the set time T level The time t can be longer than the set time T level If the time t is equal to or greater than the set time T level If it is less than the predetermined value (step S230: NO), step S230 is executed again.

[0085] In step S250 of this modified example, the preset number of determinations is set as the set number of determinations for each level N level As described above, the detection value is large and the pallet 120 that shakes a lot also has a long shaking time. level Not only the set number of judgments N level For example, the number of determinations at the high level N level The number of judgments at low level N level The number of judgments n can be set to be larger than the number of judgments N level If the number of determinations n is equal to or greater than the set number of determinations N level If it is less than (step S250: NO), step S260 is executed.

[0086] In this modification, the set time T leveland the number of set judgments N level By setting the above, the influence of the magnitude of the shaking of the pallet 120 can be suppressed.

[0087] <Third embodiment> A parking device 10 according to one embodiment of the present invention will be described with reference to Figures 12 and 13. In the description of this embodiment, the description of the same configuration as the configuration of the parking device 10 of the first or second embodiment may be omitted.

[0088] Fig. 12 is a block diagram illustrating the control configuration of the parking device 10 according to one embodiment of the present invention. As shown in Fig. 12, the stopping system 200 includes a tilt sensor 210, a control device 220, and a wind speed sensor 230. The stopping system 200 can also receive emergency earthquake alerts provided by the Earthquake Prediction and Surveillance System (EPOS).

[0089] The wind speed sensor 230 can generate a wind speed value including wind direction and wind speed. The wind speed value generated by the wind speed sensor 230 is transmitted to the control device 220.

[0090] In this embodiment, a configuration is described in which the shutdown system 200 includes a wind speed sensor 230 and is capable of receiving emergency earthquake alerts, but a configuration that does not include a wind speed sensor 230 or a configuration that does not receive emergency earthquake alerts is also possible.

[0091] Fig. 13 is a flowchart illustrating the control processing of the stopping system 200 of the parking device 10 according to one embodiment of the present invention. As shown in Fig. 13, the control processing of the stopping system in this embodiment includes steps S300 to S370. Below, the control processing of the stopping system 200 in this embodiment will be described in accordance with the order of the steps in the flowchart in Fig. 13.

[0092] Steps S300 and S310 are similar to steps S100 and S110, respectively, described in the first embodiment, and therefore will not be described again.

[0093] In step S315, the determination unit 221 determines the cause of abnormality detection for the pallet 120 based on the receipt of an emergency earthquake warning from the EPOS or a wind speed value equal to or greater than a threshold value measured by the wind speed sensor 230. For example, when an emergency earthquake warning is received, the cause of abnormality detection is determined to be an earthquake. Also, when the wind speed value is equal to or greater than a threshold value, the cause of abnormality detection is determined to be wind. In some cases, the abnormality detection cause is a combination of factors. In such cases, the cause of abnormality detection is determined according to a preset priority order for the abnormality detection factors. For example, the priority order is set so that earthquakes have a higher priority than wind.

[0094] Step S320 is the same as step S120 described in the first embodiment, and therefore a description thereof will be omitted.

[0095] In step S330, a preset time T factor can be used. Depending on the abnormality detection factor, the way the pallet 120 shakes and the inclination of the pallet 120 also differs. For example, if the abnormality detection factor is wind, the pallet 120 will shake significantly in one direction in which the wind blows. On the other hand, if the abnormality detection factor is itself, the pallet 120 will shake in a complex manner such as vertical or horizontal shaking due to an earthquake, which may result in a large inclination of the pallet 120. Therefore, the set time T factor is set to adjust the influence of the abnormality detection factor of the pallet 120. For example, in the case of an earthquake, the set time T factor In the case of wind, the set time T factor The time t can be longer than the set time T factor If the time t is equal to or greater than the set time T factor If it is less than the predetermined value (step S330: NO), step S330 is executed again.

[0096] Step S340 is the same as step S140 described in the first embodiment, and therefore a description thereof will be omitted.

[0097] In step S350, the preset number of determinations is set as the preset number of determinations for each abnormality detection factor, N factor As described above, the tilt of the pallet 120 may vary depending on the cause of the abnormality detection. factor Not only the set number of judgments N factor For example, the influence of the abnormality detection factor of the pallet 120 may be adjusted by setting the set number of determinations N factor The number of judgments in the case of wind is set as N factor The number of judgments n can be set to be larger than the number of judgments N factor If the number of determinations n is equal to or greater than the set number of determinations N factor If it is less than (step S350: NO), step S360 is executed.

[0098] Steps S360 and S370 are similar to steps S160 and S170 described in the first embodiment, and therefore a description thereof will be omitted.

[0099] In the parking device 10 equipped with the stopping system 200 according to this embodiment, the set time T factor and the number of set judgments N factor By setting this, it is possible to suppress the influence of abnormality detection factors of the pallet 120. Furthermore, for a parking device 10 that has been brought to an emergency stop without a serious accident occurring, the user can cancel the emergency stop of the parking device 10. As a result, if no serious accident has occurred in the parking device 10, there is no need to call the manufacturer or management company of the parking device 10, which reduces the burden on the manufacturer or management company of the parking device. In addition, the convenience of the parking device 10 for users is improved.

[0100] The parking devices 10 according to the first to third embodiments, including modified examples, can also be configured in appropriate combinations.

[0101] Even if there are other effects and advantages different from those brought about by the aspects of the above-described embodiments, those that are clear from the description in this specification or that can be easily predicted by a person skilled in the art are naturally understood to be brought about by the present invention.
