Description

Description: FIELD OF THE INVENTION The present invention relates to a control method for a multi-story parking lot, and more particularly to an improvement in a parking speed. More specifically, the present invention reduces the cycle time at the time of continuous storage and continuous exit,
Related to reducing waiting time. [Prior Art] Many conventional multi-story parking garages allow a vehicle to run completely on its own to enter and leave a car.
In some multi-story parking lots, elevators for transporting vehicles are provided, and in other portions, entry / exit is performed by relying on self-propelled vehicles. All of these multi-story parking lots require a large floor area due to the self-propelled space of the vehicle, and require occupants to enter and exit the parking floor, thus requiring security facilities such as emergency escape facilities on the parking floor. Furthermore, there is a problem that the surrounding environment is harmed due to the exhaust gas from the vehicle. In order to solve these problems, it is conceivable to construct a fully automated multi-story parking lot. The problem in this case is to reduce the waiting time required for entering and leaving the vehicle. This can be understood from the standpoint of a user of the multi-story parking lot, and it is inconvenient for a parking lot having a long waiting time until entry or exit. In particular, when a large number of vehicles need to be put in or taken out of the car at one time, the waiting time increases and becomes long. When constructing a large-scale multi-story parking lot, if the speed of entry and exit is slow, the parking lot will not function. Therefore, improvement of the entrance / exit speed is also important in increasing the size of the parking lot. The entrance / exit speed of the parking lot can be represented by the speed at which a large number of vehicles are continuously exited or the speed at which a large number of vehicles are continuously entered. For example, if you build a multi-story parking lot in the basement of a hotel, station, office building, etc., after the hotel's entertainment is over,
Departures are concentrated in the evening when they return home. Storage is concentrated before the start of the event, during commuting hours in the morning, and when leaving the office. In these cases, entry and exit are the slowest, and the entrance / exit speed of the multi-story parking lot is determined by the waiting time in this case. And making the customer wait for a long time to enter or leave the store loses the value of the multistory parking lot. [Problem of the Invention] An object of the present invention is to improve the speed at which a vehicle enters and exits a multilevel parking garage.
In particular, it is an object of the present invention to reduce the cycle time at the time of continuous loading and unloading, and to reduce the waiting time. [Configuration and Operation of the Invention] The control method of a multi-story parking lot according to the present invention provides a method for controlling an elevator for transporting a vehicle between a parking floor and a parking floor, and a parking pallet in the elevator and the parking floor. In the control method of a multi-story parking lot provided with a power trolley that also serves as an entrance and exit for transporting a vehicle, the elevator is provided with two types of elevators, an entrance elevator and an exit elevator, and the entrance and exit floor is provided with an entrance elevator. warehousing Bath provided in contact with, the unloading berth provided in contact with the unloading elevator, in the parking floor, before the inlet-outlet
Only along the running path of the driving truck of combined, provided the parking pallet, receipts Bath, unloading berth, receipts elevators, goods issue elevators, driving truck, each floor of the parking pallet, between which the horizontal sliding motion of the vehicle In addition to providing a conveyor for moving the vehicle at the time of continuous entry of vehicles, the vehicle is moved from the entrance berth to the entrance elevator so that the next vehicle can enter the entrance berth, the lifting cycle of the entrance elevator and the power bogie The transport cycle is performed at the same time, and when the vehicle is continuously unloaded, the vehicle is moved from the unloading elevator to the unloading berth, and the vehicle can be started from the unloading berth. Are performed at the same time. In this specification, the warehousing cycle refers to a cycle from entry into one berth by self-propelled entry to movement to a parking pallet which is a final parking position. The storage cycle time refers to the time required for storing one vehicle per storage berth during continuous storage. For example, if a vehicle can be stored from the storage berth every 40 seconds, the storage cycle time is 40 seconds. In this case, even if it takes more than one minute for the entered vehicle to arrive at the parking pallet, which is the final parking position, the movement of the transport trolley and the elevation of the elevator are simultaneously performed at the same time. Therefore, the cycle time of storage is 40 seconds. Further, in this specification, the leaving cycle refers to a cycle from the start of movement of the power bogie toward the parking pallet for one vehicle until the vehicle starts traveling by itself from the leaving berth. Similarly, the exit cycle time is an average exit interval at the time of consecutive exits per exit berth. As a concept other than the above, the storage berth cycle is a cycle from the entry of the vehicle into the storage berth to the completion of the transfer to the storage elevator. The exit berth cycle refers to the cycle from the reloading of the vehicle from the exit elevator to the start of the vehicle from the berth. The elevator raising / lowering cycle is a cycle of reciprocating lifting / lowering movement between a loading / unloading floor and a parking floor, and includes reloading the vehicle between the berth and the power bogie during this time. The transfer cycle of the power bogie is a cycle of reciprocating horizontal movement between the elevator and the parking pallet, and during this time, reloading the vehicle between the parking pallet and the elevator is included. The inventor has found that in entering and exiting this type of multi-story parking lot, the self-propelled movement of the vehicle to or from the exit berth is the slowest. That is, in order to stop the vehicle by self-running at the storage berth, the vehicle must enter the storage berth by self-running, stop the engine, and the occupant must move down from the vehicle. The same applies to the case of leaving the car, and it takes the longest time to stop and start the vehicle at the entrance / exit berth, and to get on and off the people as compared with other operations such as raising and lowering the elevator. On the other hand, the entry and exit of vehicles to and from the multi-story parking garage is based on the self-propelled
Alternatively, in the case of leaving a car, the cycle includes three cycles of self-running of the vehicle by an occupant from a leaving berth, lifting and lowering of an elevator, and movement of a power bogie within a parking floor. Therefore, if these cycles are performed simultaneously in parallel, the speed of loading and unloading can be greatly improved.
Assuming that each cycle requires the same time for simplicity, the loading / unloading speed can be improved by about three times by performing the cycles in parallel as compared with the case where each cycle is performed serially. What actually takes the longest time is getting on and off the people at the entrance / exit berth and stopping or starting the vehicle. An improvement in the entrance / exit speed is particularly required when a large number of vehicles are entered / exited continuously. Therefore, at the time of continuous loading / unloading, the elevator moving-up process and the moving vehicle moving process are performed simultaneously in parallel with the vehicle being allowed to enter and leave the entrance / exit berth, thereby improving the entering / exiting speed. Here, the entrance / exit berth and the elevator are separated so that the entrance / exit of the vehicle to / from the entrance / exit berth and the elevation of the elevator can be performed in parallel. To be able to do it. Also, in order to smoothly transfer vehicles between the entrance / exit berth, elevator and power bogie, conveyors such as rollers and belt conveyors are provided on the floors of the entrance / exit berth, the elevator and the power bogie, and the vehicle moves by sliding motion. To be moved. Further, the elevator is separated for entry and exit, and the berth is also separated for entry and exit. Although this seems to reduce the efficiency of the elevator at first glance, it is actually more efficient to separate the entrance and exit from the elevator. For example, if a berth has a garage vehicle, the garage cannot be left. If the entry and exit cycles are performed by the same elevator, it is difficult to control the elevator. On the other hand, separate for entrance and exit for storage, and if a dedicated elevator and berth are provided, respectively, while continuous entrance and exit are performed simultaneously, each elevator will perform a simple movement of entrance or exit, The moving direction of the berth or elevator conveyor is one direction, which is efficient. Also, since the berths are also separated into a garage only and a garage only, there is no problem such as the entering vehicle entering the berth waiting for the exiting vehicle from the elevator and stopping the function.
Further, the self-propelled route of the entering vehicle and the self-propelled route of the leaving vehicle can be separated, and there is no fear of collision between the two. In a simple process, the cycle time of entry and exit is the cycle time of the entrance berth and exit berth, plus the cycle time of the elevator and the cycle time of the power bogie, but in the present invention, these cycles overlap at the same time. Done and shorter than the sum of these. In particular, in continuous storage and continuous storage, cycles for different vehicles are performed simultaneously. For example, at the time of continuous warehousing, at the same time as the vehicle enters the storage berth, at the same time as the vehicle entering the storage berth, the elevator ascending / descending cycle with respect to the vehicle one vehicle before, and two or more vehicles as viewed from the vehicle entering the storage berth. The transport cycle of the power truck for the vehicle is performed. Here, the elevator elevating cycle with respect to the immediately preceding vehicle is performed because the entrance berth receives the next vehicle while the elevator is elevating. The fact that the power bogie is transporting two or more preceding vehicles means that the power bogie is transporting a vehicle that has entered the berth last time. Here, the reason why two or more vehicles are used is that if there are a plurality of parking floors,
This is because the power bogie may be carrying different vehicles at the same time on the second floor and the second floor. [Embodiment] The overall structure of a multistory parking lot will be described with reference to FIGS. In FIG.
Reference numeral 2 denotes a building of a multi-story parking lot, 4 denotes an entrance floor, and 6 denotes an exit floor. The same floor may be used for both entry and exit without distinguishing between the entry floor 4 and the exit floor 6. Hereinafter, the storage floor 4 and the storage floor 6 are collectively referred to as a storage floor. As is clear from the figure, the entrance and exit floors are preferably arranged on the ground floor of the building 2. 8
Reference numerals -1 to 8-11 denote a storage zone in which the storage elevator 9 and the storage berth 11 are set, and one storage berth 11 is provided for each elevator 9. 10-1
Reference numerals 10 to 11 denote a leaving zone in which a leaving elevator 9 'and a leaving berth 12 are set. Similarly, a leaving berth 12 is provided for each elevator 9'. Note that two storage berths 11 may be provided on both sides of the storage elevator 9 or two storage berths 12 may be provided on both sides of the storage elevator 9 ′ to enhance the capacity of the storage zone 8 and the storage zone 10. The entrance berth 11 and the exit berth 12 are provided corresponding to the front and rear wheels of the vehicle.
It consists of two power rollers. Of course, instead of the power roller, another conveyor such as a belt conveyor may be used. In the present invention, vehicle transport means such as rollers and belt conveyors are collectively referred to as conveyors. Similarly, the elevators 9, 9 'are also provided with two power rollers for transporting the vehicle. That is, the storage elevator 9 and the storage berth 1
1. The vehicle is moved between the exit elevator 9 'and the exit berth 12 by sliding the vehicle with a power roller. Reference numeral 13 denotes a pedestrian floor of the building, which is used for traffic of pedestrians from the entrance floor 4 or the exit floor 6, a shopping center, an office space, and the like. 23 is a control computer. FIG. 4 shows a plan view of the parking floor 14. For the sake of simplicity, only the exit elevator 9 'is shown in the figure, but the entrance elevator 9 is also provided. In the figure, reference numeral 16 denotes a power bogie for transporting a vehicle, and reference numeral 18 denotes a parking pallet of the vehicle. The power truck 16 and the parking pallet 18 are also provided with two power rollers, and the vehicle is exchanged between the power truck 16 and the parking pallet 18 by the sliding motion of the power rollers. Reference numeral 20 denotes a rail for moving the power truck, and the power truck 16 runs on the rail 20 by wheels (not shown). The power truck 16 has a motor (not shown). The wheels are rotated by a motor using electric power from a power supply line provided separately from the rail 20, for example, and travel on the rail 20. The power cart 16 is controlled by receiving a control signal through a signal line (not shown). In addition, as a configuration of the cart 16, a towing roller provided on the parking floor 14 is used.
It is also possible to tow a trolley. However, towing the truck with the rollers reduces the traveling speed of the truck. That is, assuming that the number of rotations of the roller and the wheel of the bogie is the same, the speed of the bogie becomes overwhelmingly larger when wheels having a larger diameter are used. Next, the diameter of the roller is directly connected to the rattling of the truck during traveling, and there is a limit to the diameter of the roller.
Also, using rollers to provide power to all of these rollers disposed on the entire surface of the parking floor 14 significantly increases the equipment cost of the multi-story parking lot. So the trolley 16
, A self-propelled carriage is used on the rail 20. FIG. 5 shows the power rollers 2 provided on the floors of the elevators 9 and 9 ′ and the power carriage 16.
2 is shown. In the embodiment, the entrance berth 11 and the exit berth 12 and the elevator 9,
Vehicle movement between 9 ', vehicle movement between elevators 9, 9' and power bogie 16, power bogie 1
All the vehicle movement between the vehicle 6 and the parking pallet 18 is performed using the power roller 22. Although not particularly shown, it is assumed that a similar power coroller 22 is also provided on the entrance berth 11, the exit berth 12, and the parking pallet 18. The power rollers 22 are power rollers and correspond to the front and rear wheels of the vehicle, and are provided at two places on the floor of the power carriage 16 and the elevators 9, 9 '. These power rollers 22 cause the vehicle to slide and move. 24
Is a bollard for fixing the vehicle to the power bogie 16. Reference numeral 26 denotes a sensor such as an ultrasonic wave for detecting the movement of the vehicle, which is used to confirm that the movement of the vehicle has started and that the movement of the vehicle has ended. Here the power rollers 22, and side-slip power roller. This is to prevent the vehicle from sliding longitudinally with respect to the power roller 22 .
Also instead of in correspondence with the front and rear wheels of a vehicle provided with two power rollers, using a single power roller longitudinal, which may correspond to both the front and rear wheels. The operation of the device will be described. The vehicle that has entered the storage floor 4 travels to the storage berth 11 by itself, and the occupant gets off there. Subsequent entry work is automatically performed, and the occupant may enter a shopping center or the like in the building from a passage (not shown). In the case of leaving the vehicle, the occupant only needs to get into the vehicle in the retrieval berth 12 from the pedestrian passage 13, travel by himself, and exit from the retrieval floor 6. In the embodiment, since there is no reversing operation of the direction of the vehicle, the vehicle entering the storage floor 4 exits to the exit floor 6 in the same direction. Therefore, the traveling of the vehicle to the retrieval floor 6 does not require a change in direction. Also, if the incoming floor 4 and the outgoing floor 6 are separated,
The flow of the vehicle is not congested, and the flow of the vehicle is natural. During this time, the pedestrian passage 13
, The flow of people becomes natural. FIG. 1 shows an operation mode of the embodiment, taking a case of continuous entry and exit of a vehicle as an example. The process for moving the vehicle into and out of the vehicle separately is simple, and is evident from the process for successively moving in and out of the vehicle. FIG. 2A shows an operation mode when all the operations are performed serially.
9 shows an operation mode when the elevator 9 'is moved up and down and the power carriage 16 is moved in parallel. These figures show an example of leaving the vehicle, but the same applies to entering the vehicle. FIG. 6 shows an operation algorithm of the embodiment. Of the symbols such as 2-1 in FIG. 1, the first 2 represents the number of the vehicle being processed, and the second 1 represents each process in the processing cycle. Regarding the exit berth 12, process 0 refers to the movement of the vehicle by the power rollers from the elevator 9 ', and process 1 refers to the self-running of the vehicle by the occupant. For the elevator 9 ′, the processing 1 is for moving the elevator 9 ′ to the parking floor 14, the processing 2 is for exchanging the vehicle with the power bogie 16 by the power roller, and the processing 3 is for moving the elevator 9 ′ to the exit floor 6. 'Move. Process 4 refers to moving the vehicle to the exit berth 12 using the power roller. Regarding the parking floor 18, process 1 involves moving the trolley 16 to the parking pallet 18, process 2 involves exchanging the vehicle with the parking pallet 18 using power rollers, and process 3 occurs before the elevator 9 '. The process 4 refers to the transfer of the vehicle to the elevator 9 'by the power roller. It is assumed that the vehicle is requested to be taken out of the vehicle continuously. In the embodiment, the door of the elevator 9 ′, which has been waiting at the same time as the unloading berth 12 becomes empty, opens and the power roller 22
The vehicle is sent out from the elevator 9 'to the exit berth 12 by using. This work
The operation is performed after the two conditions of the end of the movement of the elevator 9 ′ and the empty space of the exit berth 12 are satisfied. Self-propelled retrieval is the slowest operation, and in many cases, the elevator 9 'waits for the retrieval berth 12 to be vacant on the retrieval floor 6. Therefore, the next vehicle arrives at the exit berth 12 almost at the same time that the preceding vehicle starts from the exit berth 12 and the exit berth 12 becomes empty. Further, in the embodiment, the vehicle may be started or entered not in the narrow elevators 9 and 9 ′ but in a wide outside exit berth 12 or entrance berth 11. Therefore, there is little feeling of psychological pressure on the occupants, and the large space allows easy self-propelled driving. When the operation of moving the vehicle by the power roller 22 is completed, the occupant gets on the vehicle and leaves the vehicle. At the same time, the elevator 9 'moves to the next parking floor 14. On the other hand, independently of this, each power bogie 16 moves the vehicle that has received the command to a position short of the elevator 9 '. That is, the power cart 16 moves to the required parking pallet 18, and the vehicle is mounted on the power cart 16 from the parking pallet 18 by the power roller 22, and the elevator 9
Move to just before '. Then, waiting for the arrival of the elevator 9 ', or when the movement of the power carriage 16 is slow, the elevator 9' waits for the arrival of the power carriage 16 to move the vehicle by the power roller 22. Here, the elevator 9 'is raised and lowered and the power bogie 16
And move simultaneously. Thereafter, the elevator 9 'moves to the retrieval floor 6, waits for the retrieval berth 12 to become empty, and sends out the vehicle. Of these operations, it is necessary to synchronize the vehicle movement between the elevators 9, 9 'and the entrance berth 11 and the exit berth 12, and the elevator 9, 9'.
9 ′ and a power bogie. Therefore, the operations of the storage berth 11, the exit berth 12, the elevators 9, 9 ', and the components of the power bogie 16 can be advanced simultaneously, and a waiting time can be set for a slower one. Here, the processing time of entry and exit is considered. When entering and exiting the vehicle continuously, the slowest is the entry and stop of the vehicle into the normal entrance berth 11 by self-propelled, and the departure of the vehicle from the exit berth 12 by self-propelled. Therefore, the self-propelled operation of the preceding vehicle to the entrance berth or the self-propelled operation from the exit berth is completed, and the processing of the next vehicle is enabled. In the case of carrying out the storage separately, since the elevator 9 is already waiting in the storage berth 11, the vehicle moves to the elevator 9 by the power roller at the same time as the vehicle 9 enters the storage berth by self-propelled. In addition, in the case of leaving the warehouse separately, at the same time as the elevator 9 ′ moves to the parking floor 14, the vehicle requiring the power bogie 16 is moved to the front of the elevator 9 ′. Therefore, the substantial required time is only about the round trip time of the elevators 9, 9 '. FIG. 6 shows an outline of the control algorithm. Upon receiving a command to enter and leave, each element of the elevators 9, 9 ', the entrance berth 11, the exit berth 12, and the power bogie 16 inputs a new instruction at the end of their respective queues. Each element performs processing from the head of its own queue, and when its responsibility is over, it deletes the head of the queue and starts processing the next command in the queue. There is not a single queue, but a queue for each of the elevators 9, 9 ', the entrance berth 11, the exit berth 12, and the power cart 16, and independently processes its own work from the beginning. There is unevenness in speed and load of each element. The loading of the entrance berth 11 and the exit berth 12 is the highest, and the elevator 9,
9 'is second to this, and the load of the power bogie 16 is low. Then, waiting for the preparation of the delivery partner of the vehicle to be completed (this is called positioning in FIG. 6), the vehicle is delivered. If the alignment condition is not satisfied, the element that has completed processing first enters a wait state. When the delivery is completed, the element that has completed the work processes the next command. Elements that have not received the command (for example, the power truck 16 on the floor that has not received the loading / unloading command) enter a rest state. [Effects of the Invention] According to the present invention, the entrance and exit speed of the multilevel parking lot is increased, and the waiting time of the customer is reduced.
In addition, the reduction of waiting time enables the multi-story parking lot to be enlarged. In this invention, in particular, a storage elevator and a release elevator are separately provided to facilitate continuous storage and continuous release, furthermore, a storage berth is connected to the storage elevator, and a storage berth is connected to the storage elevator, And the flow of outgoing cars are separated. As a result, the safety of entering and exiting the store is increased, and guidance of the occupants becomes easier. According to the present invention, a control method for performing continuous storage and continuous release in a short time is provided, and the cycle time of continuous storage and continuous release is minimized. According to the second aspect of the present invention, a plurality of parking floors are provided, and the parking and retrieving to and from another vehicle are simultaneously performed for each parking floor, thereby shortening the parking and retrieving cycle. For example, one vehicle is transported by the power bogie on the first parking floor, and at the same time another vehicle is transported on the second parking floor, and the elevator is efficiently operated without waste. Allows the vehicle to enter or depart continuously. In particular, according to the third aspect of the present invention, the entry / exit floor is provided on the ground floor to facilitate access to and from the road.
