JP4391247B2 - On-site monitoring system for multistory parking lot - Google Patents

Description

  The present invention relates to a monitoring system for monitoring the inside of a multilevel parking lot at the entrance / exit floor, and particularly, whether or not the driver (and passenger) of the vehicle entering the multilevel parking lot has left the inside of the entrance / exit floor of the parking lot. The present invention relates to an on-site monitoring system for a multi-story parking lot that more reliably detects the situation and improves the safety of the user.

  In general, a multilevel parking garage equipped with a mechanical parking device is provided with an entry / exit floor (also referred to as an entry / exit section or an entry / exit room) defined at one or a plurality of locations. A driving operation panel is provided outside the venue. Then, by operating the operation panel, an empty pallet (or a cage, or an elevator with a comb fork in a palletless type multi-level parking garage) is called to the entry / exit floor and placed at a predetermined position. The door opens, and the vehicle enters the pallet by the driving of the vehicle driver and stops at the normal position.

  After that, the driver (the passenger will get off outside before boarding) gets off and exits from the entrance / exit, and the entrance / exit door closes with the safety check inside the entrance / exit floor. A series of goods receipt work is completed. Thereafter, the pallet on which the vehicle is mounted by driving a mechanical parking device is transported to a predetermined parking space or the like as necessary.

  In such a multistory parking lot, after entering the warehouse, the entrance / exit door is closed and the mechanical parking device is driven. It has become.

  Therefore, as a method for confirming the presence or absence of a person in such a field, a structure for detecting the shading or movement of a person by a photoelectric detector, an infrared detector, an ultrasonic detector, etc., or an image taken by an imaging device Various structures for detecting a person by processing, and a structure for electrically detecting a person moving on a mat-like pressure-sensitive switch arranged on the floor have been proposed (for example, Patent Documents 1, 2, and 3). 4, 5, 6).

  Various proposals have also been made with a device for detecting whether the vehicle is overloaded by detecting the weight of the vehicle mounted in advance, from the viewpoint of ensuring safety when moving up and down such as a pallet on which the vehicle is mounted. (For example, see Patent Documents 7, 8, and 9).

  However, according to the conventional structure for checking presence / absence of a person in a multi-story parking lot as described above, it is a structure for detecting a person at a specific place in a passage or a vehicle in the field. There is a problem in that there is a lack of certainty of human existence because there are many blind spots in the parts captured by the imaging device due to the structure of the vehicle itself (seat seats, privacy glass windows, etc.), the structure of the parking lot, etc. .

  In addition, once the driver or passenger who has left the site enters the venue again, it takes too much time to enter the vehicle mounted on the pallet or the like and search for luggage or small items, and the timer of the operation control device has elapsed. There was a possibility that the entry / exit door could be closed and timed out.

  Therefore, in view of the above points, the present invention provides an on-site monitoring system for a three-dimensional parking lot that can more reliably detect the presence / absence of a person in the vehicle, and moreover, a three-dimensional parking lot that more reliably prevents people from being trapped in the place. The purpose is to provide an on-site monitoring system.

The technical means for solving the above-mentioned problems includes a lifting platform that is operated to move up and down along the hoistway, and the vehicle is mounted and stored on the lifting platform called up on the entry / exit floor. In the on-site monitoring system for a multistory parking lot, the vehicle has weight detection means for detecting the weight of the vehicle stored on the lifting platform called to the storage floor, and the weight of the vehicle stored on the lifting platform is determined. After detecting and obtaining the vehicle weight at the time of warehousing, the weight of the vehicle mounted on the lifting platform is detected to obtain the vehicle weight after mounting, and the weight difference between the vehicle weight at the time of warehousing and the vehicle weight after mounting is obtained. And a control unit that determines whether or not a person is present based on whether or not the difference in weight is within a preset range corresponding to the weight of the person, and the vehicle weight after mounting is obtained after the closing operation of the entrance door. The weight difference of the person is If within a preset range corresponding to the amount min, certain goods movements outlet door provided in the front inlet-outlet floor to the point of opening control.

  Furthermore, the multi-story parking lot includes a person detection unit that detects the presence of a person in the entry / exit floor, and the control unit is configured to detect the presence of a person in the entry / exit floor by the person detection unit. May have a structure in which the entrance / exit door is not closed.

  Further, the human detection means may have a structure including any one of a photoelectric detector, an infrared detector, an ultrasonic detector, a sound detector, a tread pressure detector, an imaging device, or a combination thereof.

According to the on-site monitoring system for a multilevel parking garage according to claim 1, the system includes weight detection means for detecting the weight of a vehicle stored on a lifting platform called up on a loading / unloading floor, and is stored on the lifting platform. After detecting the weight of the vehicle and obtaining the vehicle weight at the time of warehousing, the weight of the vehicle mounted on the lifting platform is detected to obtain the vehicle weight after the loading, and the weight difference between the vehicle weight at the time of warehousing and the vehicle weight after the loading Therefore, the weight difference is equal to the weight of the person because the weight difference is within a preset range corresponding to the weight of the person. If it is not within a preset range corresponding to, it is determined that there is still a person in the vehicle, and if the weight difference is within a preset range corresponding to the weight of the person, It is determined that a person has left the vehicle, where Is a method for determining the exit of a person in the vehicle, and does not cause a blind spot like the method of determining the presence or absence of a person by imaging of a conventional imaging device, can more reliably detect the presence or absence of a person in the vehicle, It is possible to effectively prevent people from being trapped in the hall.

In addition, the vehicle weight after mounting is obtained after the closing operation of the entry / exit door, and if the weight difference is not within a preset range corresponding to the weight of the person, the entry / exit floor Because the structure is designed to control the opening of the entrance door , even after the closing operation, the entrance door can be opened by detecting the presence of a person, effectively preventing people from being trapped in the hall. .

  In addition, the multistory parking lot includes a person detection means for detecting the presence of a person in the entry / exit floor, and the control unit detects the presence / absence of a person in the entry / exit floor by the person detection means. Since the door is not closed, the presence / absence of the person is detected not only in the vehicle but also in the place on the entry / exit floor, so that the confinement of the person in the place can be more effectively prevented.

  In particular, when the presence of a person is not detected by the human detection means, the entrance / exit door is closed, and then the vehicle weight after installation is obtained, and the weight difference between the vehicle weight at entry and the vehicle weight after installation is calculated. Even when the presence of a person is detected, the entrance / exit door is controlled to open, so that it is possible to effectively prevent people from being trapped in the hall.

  Furthermore, if the human detection means has a structure composed of any one of a photoelectric detector, an infrared detector, an ultrasonic detector, a sound detector, a tread pressure detector, an imaging device, or a combination thereof, as described above. In addition, people can be effectively prevented from being trapped in the hall.

  Then, control is performed so that the entry / exit of the vehicle 10 is detected by shielding the beams of the photoelectric detectors PH1, PH2. For example, after the photoelectric detector PH1 is shielded, the photoelectric detector PH2 is also shielded in that state. If it is determined that the vehicle 10 has been received, and the photoelectric detector PH2 is shielded from light, then if the photoelectric detector PH1 is also shielded in that state, it is determined that the vehicle 10 is leaving. Further, the photoelectric detector PH2 has a structure that also functions as a detector for regulating the rear end position of the vehicle 10. If the vehicle 10 entering the vehicle shields the beam of the photoelectric detector PH2, the photoelectric detector PH2 is urged to advance. Be controlled.

  The photoelectric detector PH4 functions as a detector for restricting the stop position of the vehicle 10, and it is determined whether or not the vehicle 10 is mounted on the pallet 12 by light shielding of both the photoelectric detector PH3 and the photoelectric detector PH4. .

  The photoelectric detector PH5 functions as a detector for restricting the front end position of the vehicle 10, and is controlled so as to promote backward movement when the incoming vehicle 10 shields the beam of the photoelectric detector PH5. In addition, if the beam is shielded by both the photoelectric detector PH2 and the photoelectric detector PH5, the vehicle length is over and the vehicle is controlled to be urged.

  Each of the photoelectric detectors PH6 and PH7 functions as a left end and right end regulating detector of the vehicle 10, and is controlled so as to prompt the user to forget to close the door or to exit the vehicle when the vehicle width is exceeded by shielding the beam.

Here, these photoelectric detectors PH1, PH2, PH6, PH7, etc. have a structure that is also used as a human detection means for detecting the presence of a person in the place on the entry / exit floor.

  Further, a driving operation panel 39 for controlling the operation of the parking device 1 is provided at one side of the entrance / exit 33 outside the venue. As shown in FIG. A power switch 40 for turning on / off, a numeric keypad 41 for inputting various operation information such as a self ID number when used by a user, a speaker 42 also serving as voice guidance and an alarm device, an emergency stop switch 43, an information display A display unit 44 made of liquid crystal or the like is provided.

  The control device 45 includes a control unit 45 that controls the driving of the parking device 1. The control device 45 includes a CPU 45 a, a memory 45 b, and the like. Up / down control of the pallet 12 by the pallet transfer device 19, turning control by the pallet turning device 20, weight detection control of the vehicle 10 by the load cell 29, opening / closing control of the entrance / exit door 34, from the speaker 42 or the like in case of abnormality Alarm control for issuing an alarm, detection control of the vehicle 10 and people by receiving and blocking the beams of the photoelectric detectors PH1 to PH7, and the like are performed.

  Next, the control of the entering / exiting operation of the vehicle 10 in the parking apparatus 1 will be described based on the flowcharts shown in FIGS.

  First, it is determined whether or not a call operation for entering / exiting has been performed (step S1). If there is a call operation, it is determined whether or not the call operation is for entering (step S2). Called (step S3).

  At this time, whether the vehicle 10 to be stored is the high roof vehicle HR is determined by a method of detecting the height of the vehicle 10 by a detector such as an optical sensor appropriately disposed in front of the loading / unloading port 33, An input method or the like may be adopted as appropriate depending on the situation. And the empty pallets 12 of the parking racks 11L and 11R corresponding to the vehicle height of the vehicle 10 are called. In addition, even if it is the structure which controls so that the empty pallet 12 for high roof cars HR may be called if there is no empty pallet 12 for normal cars SR in the normal car SR where the vehicle height of the vehicle 10 to be stored is not high. Good.

  Thereafter, it is determined whether or not the empty pallet 12 has arrived at the entry / exit floor (step S4). If the called empty pallet 12 arrives at the entry / exit floor, the entry / exit door 34 at the entry / exit entrance 33 is opened. Then, the driver drives the vehicle 10 and gets on the empty pallet 12 mounted on the lifting platform 8 (step S6).

  Then, it transfers to step S7, it is judged whether the vehicle 10 has stopped at the regular position by the detection state of each photoelectric detector PH1-PH7 with which the entrance / exit floor was equipped, and it has not stopped at the regular position. In this case, the driver is informed to stop at the normal position by the guidance display of the normal position stop by the guidance display board 36 and the voice guidance by the speaker provided therein (step S8).

When only the photoelectric detectors PH3 and PH4 are in the light-shielding detection state and the other photoelectric detectors PH1, PH2, and PH5 to PH7 are stopped at the normal positions in the light reception detection state, the timer 10 is set in advance. Time measurement for a predetermined time T1 (for example, in units of 5 seconds or constant detection) is started (step S9), the weight of the vehicle 10 stored on the pallet 12 is detected by the load cell 29, and the detected weight value is the vehicle at the time of storage. The weight W ₁ is taken in (step S10).

As a method of detecting the vehicle weight W ₁ at the time of warehousing, for example, the weight difference before and after the vehicle 10 enters the pallet 12 is detected by each load cell 29, and a load signal corresponding to the total detected load may be output. The conventional detection methods and processing methods disclosed in Japanese Utility Model Laid-Open Nos. 6-78538, 6-53573, and 6-32564 may be appropriately employed.

Thereafter, guidance display for getting off the vehicle 10 and leaving the parking device 1 is performed by the guidance display board 36 or the like (step S11). Then, it is determined whether or not the predetermined time T1 set in the timer has elapsed (step S12). When the predetermined time T1 has elapsed, the weight of the vehicle 10 stored on the pallet 12 is detected again in the same manner as described above. The detected weight value is taken in as a vehicle weight W ₂ after mounting (step S13).

Then, whether the following vehicle weight limit weight Wz after the captured mounted vehicle weight W ₂ is in the parking device 1 is determined (step S14), and if the vehicle weight W ₂ is less vehicle weight limit weight Wz after mounting Then, the weight difference W ₃ between the vehicle weight W ₁ at the time of entry and the vehicle weight W ₂ after installation is obtained by calculation (step S15), and the obtained weight difference W ₃ is set to the preset minimum weight difference WL and maximum weight difference. It is determined whether it is within the range of WH (step S16). The weight of light cars, ordinary cars, high roof cars, large cars, etc. is 1000 kg to 2000 kg, and the vehicle weight limit weight Wz is set to a suitable numerical value such as 2300 kg, for example. In addition, the vehicle weight W ₁ at the time of entry includes not only the weight of the vehicle 10 but also the weight of the driver and luggage, and the minimum weight difference WL is, for example, 40 kg in consideration of a small person getting off the vehicle. As the maximum weight difference WH, an appropriate numerical value such as 120 kg is set in advance in consideration of a case where a large person gets off.

Then, to be in the weight difference W ₃ within the above range in step S16, it is determined that there still remains the driver in the vehicle 10, carried by the guide panel 36 such guidance display alighting and exit (step S17 ). Then, counting of the predetermined time T1 set in the timer is started again (step S18), and the process returns to step S12.

Also, if within the weight difference W ₃ ranging in step S16, in blackout detection state only photoelectric detector PH3, PH4, other photoelectric detector PH1, PH2, determines whether PH5~PH7 light receiving detection state In step S19, if any one of the other photoelectric detectors PH1, PH2, and PH5 to PH7 is in the light-shielding detection state in addition to the photoelectric detectors PH3 and PH4, it is determined that a person is in the field. If only the photoelectric detectors PH3 and PH4 are in the light shielding detection state and the other photoelectric detectors PH1, PH2, and PH5 to PH7 are in the light reception detection state, it is determined that the driver has exited, and the entrance / exit door 34 Is closed (step S20).

  And when the entrance / exit door 34 is closed, the elevator 8 on which the vehicle 10 is mounted rises, and the pallet 12 on which the vehicle 10 is mounted is transferred to the original parking racks 11L and 11R. (Step S21), and a series of work is completed.

In step S14, if it is determined that the mounted vehicle weight W ₂ is heavier than the vehicle weight limit weight Wz, it is determined that the vehicle weight is over, and the vehicle 10 cannot enter the vehicle due to the vehicle weight over and guidance for leaving the vehicle 10. The display is notified to the driver through the guidance display board 36, a speaker, or the like (step S22).

Then, timing of a predetermined time T2 (for example, 15 seconds) preset in the timer is started (step S23), and then it is determined whether or not the predetermined time T2 has passed (step S24). When the predetermined time T2 has elapsed, said detected weight on the pallet 12 in the same manner, the weight detection value is taken as the exit weight W ₄ (step S25).

Thereafter, it is determined whether or not the exit weight W _{4 taken in} is substantially the same as the initial weight W ₀ before the vehicle 10 enters the pallet 12 (step S26). It is determined that it has not moved, and the process returns to step S22.

Further, in step S26, if it is substantially the exit weight W ₄ and initial weight W ₀ is the same for all the photodetectors PH1~PH7 shifts is determined whether the light receiving detection state in step S27, one of If the photoelectric detectors PH1 to PH7 detect the light-shielding state, it is determined that the vehicle is in the middle of delivery and stands by. If all the photoelectric detectors PH1 to PH7 are in a non-detection state where the light-shielding state is not detected, it is determined that the vehicle 10 has left the field, and the entrance door 34 is closed, and the entrance door 34 is opened. Close (step S28).

  Then, the lifting / lowering table 8 stands by on the loading / unloading floor with the empty pallet 12 mounted thereon, and a series of work is completed (step S29).

  In step S2, if the calling operation is not a warehousing but a warehousing, the process proceeds to step S30, where the pallet 12 requested for warehousing is called to the warehousing / removing floor, and the called pallet 12 has arrived at the warehousing / leaving floor. Is determined (step S31).

  When the pallet 12 arrives at the loading / unloading floor, the pallet 12 is turned 180 degrees by driving the pallet turning device 20, the direction of the mounted vehicle 10 is changed, and the direction of the vehicle 10 is the direction of the loading / unloading port 33. (Step S32).

  When the direction change by the pallet turning device 20 is completed, the entry / exit door 34 is opened (step S33), the user enters the parking device 1, gets into the vehicle 10, and exits by forward driving (step S33). S34).

  Thereafter, the process proceeds to step S27, where it is determined whether or not the vehicle 10 has exited, and when the delivery is detected, the entry / exit door 34 is closed (step S28), and the elevator platform 8 is an empty pallet. 12 is mounted on the loading / unloading floor, and a series of work is completed (step S29).

This embodiment is constructed as described above, determine the weight difference W ₃ between the goods receipt when the vehicle weight W ₁ and the mounting post vehicle weight W _2, depending on whether the range that weight difference W ₃ is set in advance This is a control method for determining whether or not the driver has left the vehicle 10 that has entered the pallet 12, and compared with a conventional method for determining the presence or absence of a person through imaging by an imaging device, Since it is a method for determining the exit of a person in the vehicle 10, a blind spot as in the prior art does not occur, the presence or absence of a person in the vehicle 10 can be detected more reliably, and the confinement of a person in the field can be effectively prevented. .

  In addition, each photoelectric detector PH1 to PH7 is also used as a human detection means for detecting the presence of a person outside the vehicle 10 in the hall, and not only in the vehicle 10 but also in the hall on the entry / exit floor. It has a structure in which the presence / absence is detected to prevent an inadvertent closing operation of the entrance / exit door 34, and there is an advantage that it is possible to more effectively prevent people from being confined in the field and to share the members.

In the above embodiment, the exit of a person in the vehicle 10 is determined based on the weight difference W ₃ between the vehicle weight W ₁ at the time of warehousing and the vehicle weight W ₂ after installation, and the vehicle in the field is detected by the photoelectric detectors PH1 to PH7. 10 shows the control for closing the entrance door 34 after judging the exit of an outside person. After stopping at the regular position in step S7, the photoelectric detectors PH1 to PH7 When the presence of a person is not detected, the entrance / exit door 34 is closed automatically or artificially, and after the entrance / exit entrance door 34 is closed, the vehicle weight W ₂ after loading is taken in, and the weight difference W ₃ is calculated. It is good also as control which calculates | requires and determines the presence or absence of the person in the vehicle 10. FIG.

  In this case, if the presence of a person in the vehicle 10 is detected, a control method for opening the entrance / exit door 34 may be used. Moreover, the control etc. which alert | report the presence of a person with the speaker 42 to the driver etc. who are thought to be still near the parking apparatus 1 may be sufficient.

  Furthermore, in this embodiment, although the elevator type parking apparatus 1 by the pallet 12 system is shown, it can be applied to other parking apparatus structures such as a vertical circulation system and an underground pallet circulation system. Without using the vehicle, the vehicle 10 is directly mounted on the conveyor mounted on the elevator 8, the vehicle 10 tire is mounted on the comb fork formed on the elevator 8, or the elevator 8 A so-called pallet-less parking apparatus that does not use the pallet 12 such as a system in which the tires of the vehicle 10 are sandwiched between the formed pair of front and rear slide forks may be used.

  Further, although the structure using the load cell 29 as the weight detecting means is shown, other detecting means such as other strain gauge methods may be used as disclosed in JP-A-3-238278, etc. Not limited to anything.

  Furthermore, although the structure provided with the weight detection means in the lifting platform 8 is shown, it is good also as a structure which provides a weight detection means on the floor surface side of the pit 31 which supports the lifting platform 8 called to the loading / unloading floor. The position of the form is not limited at all.

  Moreover, although the structure using photoelectric detectors PH1 to PH7 as human detection means is shown, a known infrared detector is used in place of each photoelectric detector PH1 to PH7, and human detection is performed by receiving or shielding the infrared detector. May be a method for detecting the presence or absence of the vehicle 10 and the loading / unloading of the vehicle 10, and provides the same effect.

  Furthermore, as such a human detection means, a structure that detects the presence or absence of a person by detecting the movement of a person by a known ultrasonic detector, or a person's speaking voice or walking by a voice detector such as a known sound collecting microphone. A structure for detecting the presence or absence of a person by detecting sound, or a stepping pressure detector such as a so-called mat-type pressure sensitive switch that detects the pressure of walking on the floor is arranged, and the presence or absence of a person is detected by detecting the walking pressure. A structure for detecting or an image pickup device such as a known CCD camera may be arranged, and a structure for detecting the presence or absence of a person by image processing picked up by the image pickup device may be adopted. In addition to the performance, the detection range of the presence / absence of a person becomes wider, and there is an advantage that the blind spot of detection is reduced.

  Moreover, it is good also as a structure using combining these photoelectric detectors PH1-PH7 as a human detection means, an infrared detector, an ultrasonic detector, an audio | voice detector, a tread pressure detector, and an imaging device in combination. In this case, the number of blind spots for detecting the presence / absence of a person by each device becomes smaller, the detection of the presence / absence of a person becomes more reliable, and the confinement of a person in the field can be prevented more reliably.

  Furthermore, although the pallet turning device 20 shows a structure that turns 180 degrees, in the case of a structure in which the entrance / exit port 33 is arranged on the side of the parking structure 2, a control method that turns 90 degrees is adopted. Good.

  Moreover, although the parking apparatus 1 which can store the normal vehicle SR and the high roof vehicle HR with different vehicle heights in a mixed manner is shown, a method of storing only the normal vehicle SR or only the high roof vehicle HR may be used.

  Furthermore, although the parking apparatus 1 having a structure in which the entry / exit floor is a ground floor is shown, a structure in which two floors other than the ground floor are entry / exit floors may be used, and there are a plurality of entry / exit floors. The structure provided in the location may be sufficient and it is not restricted to the said embodiment at all.

It is the external appearance perspective view which removed some exterior plates of the elevator type parking apparatus which concerns on embodiment of this invention. It is the same section sectional front view. FIG. 3 is an enlarged sectional view taken along line III-III in FIG. 2. It is sectional drawing in the state where the said lifting platform arrived at the entering / exiting floor. It is sectional drawing of the state which the same lifting stand raised. It is a front view of the same entrance / exit part. It is the same control block diagram. It is a flowchart of an entering / exiting operation | movement. It is a flowchart of an entering / exiting operation | movement. It is a flowchart of an entering / exiting operation | movement.
