Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a vehicle storage control method.

[Conventional technology]

In recent years, vertical circulation type mechanical parking devices have been widely used as vehicle parking facilities for effectively utilizing space. This parking device has a plurality of cages for storing vehicles connected in a ring shape so as to be rotatable. When the parking device is rotated and the cage in which no vehicle is stored is moved to the landing position,
It becomes possible to store a vehicle in the cage.

Conventionally, control of this parking device has been performed mainly with emphasis on the left and right weight balance based on the landing position. As an example, in a parking device 82 formed by connecting 12 cages 80 as shown in FIG. Then, every other cage 80 (in ascending order of numbers shown in FIG. 7(A)) is moved to the landing position and the vehicle is stored.

This prevents the left and right weight balance from being disrupted by the weight of the stored vehicle. After the number of stored vehicles reaches 50%, the vehicles are sequentially moved to the landing position starting from the unstored cage 80 closest to the landing position (in ascending order of numbers shown in FIG. 7(B)) and stored. Thereby, the cages are sequentially moved starting from the cage closest to the landing position, so that the cage calling time can be shortened.

In this way, we are able to extend the life of the parking device by performing control that emphasizes the left and right weight balance, and also reduce power consumption by shortening the cage calling time and reducing the amount of rotation of the parking device. ing.

[Problem to be solved by the invention]

However, the control of the parking device mainly focuses on the left and right weight balance, and it has not been sufficient to shorten the car calling time and reduce the amount of rotation of the parking device. For example, until the number of vehicles stored reaches 50%, control is performed that emphasizes weight balance, so cages that have a long travel distance are placed on the floor in order to store every other cage even if the adjacent cage does not contain any vehicles. I had to move it to a certain position.

The present invention has been made in consideration of the above facts, and an object thereof is to obtain a vehicle storage control method that can further shorten the average time for calling the car and reduce the amount of rotation of the parking device. .

[Means to solve the problem]

In order to achieve the above object, a vehicle storage control method according to the present invention includes a plurality of cages for storing vehicles connected in a ring to be rotatable, and a vehicle can be stored with respect to the cage at the landing position. A vehicle storage control method for storing a vehicle by rotating a circulating mechanical parking device to move one of the cages in which no vehicle is stored to a landing position, the method comprising: Divide into blocks, determine the number of blocks that can be ignored in terms of weight balance, and as long as the number of blocks containing vehicles is smaller than the difference obtained by subtracting the number of blocks from the total number of blocks, vehicles can be placed in any cage in each block. is stored, and after the number of blocks storing the vehicle becomes equal to the difference obtained by subtracting the number of blocks from the total number of blocks, the vehicle is stored in a cage that can be moved to a landing position in the shortest time. It is characterized by

In addition, the number of blocks that can be ignored in terms of weight balance is
Preferably, it is an integer that does not exceed the value obtained by dividing the difference obtained by subtracting the number of cages located on the vertical line passing through the landing position from the total number of cages by 4 and the predetermined number.

Furthermore, the vehicle storage control method can sequentially store vehicles in adjacent blocks as long as the number of blocks storing vehicles is smaller than the difference obtained by subtracting the number of blocks from the total number of blocks.

[Effect]

In the present invention, a plurality of cages is divided into a plurality of blocks containing a predetermined number of cages, and the number of blocks storing vehicles is smaller than the difference obtained by subtracting the number of blocks that can be ignored in terms of weight balance from the total number of blocks. stores a vehicle in one of the cages in each block. For this reason, the period of controlling storage with emphasis on the left and right weight balance is shorter than in the past, where control is performed with emphasis on the weight balance until the number of vehicles stored reaches 50%. Further, after the number of blocks in which the vehicle is stored becomes equal to the difference obtained by subtracting the number of blocks from the total number of blocks, the vehicle is stored in a cage that can be moved to a landing position in the shortest possible time. Therefore, compared to the conventional control in which the car calling time is taken into consideration after the number of stored vehicles reaches 50%, control is performed that emphasizes the car calling time from an early stage.

Therefore, the average time for calling the car can be further shortened, and the amount of rotation of the parking device can be reduced.

In addition, the number of blocks that can be ignored in terms of weight balance is an integer that does not exceed the value obtained by dividing the difference obtained by subtracting the number n1 of cages located on the vertical line passing through the landing position from the total number N of cages by 4 and the predetermined number. By doing so, the maximum value of the number of blocks that can be ignored without disturbing the weight balance can be determined, and the average cage calling time can be further shortened.

That is, since cages located on the vertical line passing through the landing position do not affect the weight balance, it is sufficient to consider the weight balance for N-nl cages.

The number of cages that affect the weight balance on the left and right sides is (N
−nl)/2. If more than 50% of the caged vehicles out of this number (N-nl)/2 are stored, the weight balance will be disrupted compared to the conventional method.
2) The following is the number of cages that can be ignored in terms of weight balance. The number of blocks is x11 The number of cages included in the block is n
If it is set to 2, blocks that satisfy 2 · n · rB can be ignored.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

The following explanation uses numerical values that do not interfere with the present invention, but
The present invention is not limited to this value.

FIG. 1 shows a circulating mechanical parking system 10 to which the vehicle storage control method of the present invention can be applied.

The parking device 10 has 28 cages 30 that can store vehicles.
57, and each cage is connected in an annular manner by a connecting means 22 such as a chino. Parking device 10
is guided by a guide rail (not shown) and can rotate in the forward direction (in the direction of the arrow in FIG. 1) and in the reverse direction (in the direction of the arrow B in FIG. 1).

Also, the cage 30 shown at the lowest position in FIG.
The position corresponding to is considered to be the landing position.

When the parking device 10 rotates and is moved to the landing position, the cage can store a vehicle.

Further, a parking device drive device 12 is disposed near the landing position. The parking device drive device 12 includes a motor that generates a driving force, and a transmission means such as a gear that transmits the driving force of the motor to a connecting means such as a chino. The parking device driving device 12 drives the parking device 10 by the driving force of the motor.
can be moved in the forward direction (in the direction of arrow B in FIG. 1) and in the reverse direction (in the direction of arrow B in FIG. 1). The parking device drive device 12 is connected to a control device 14 .

The control device 14 is a device composed of a microcomputer or the like, and an operation panel 16 is connected to the control device 14. The operation panel 16 is equipped with a cage call button 18. The car call button 18 is operated when the vehicle is stored, and the car is called by operating it. Further, the operation panel 16 is provided with a large number of switches (not shown), and by operating these switches, an arbitrary cage is moved to the landing position when the vehicle is taken out of the garage or the like. Further, the control device 14 is connected to a notification means 20 that can notify that the parking device 10 is “full.” This notification means 20 can be composed of a buzzer, a lamp, a display, etc.

In this example, a block consisting of two cages is defined as shown in FIG. 2, and 28 cages 30 to 57 are divided into 14
It is divided into blocks 60 to 73. In addition, in this example, the total number of cages N is 28, the number n1 of cages located on the vertical line L passing through the landing position is 2, and the number n2 of cages constituting one block is 2, so in terms of weight balance. The number of blocks that can be ignored is as follows.

-3.25 Since the number of blocks is an integer that does not exceed the value determined by the above formula, it is set to "3" in this embodiment.

The control device 14 stores this value as the number of blocks that can be ignored in terms of weight balance.

Next, the operation of this embodiment will be explained with reference to the flowchart of FIG. Note that this flowchart is executed when the cage call button 18 on the operation panel 16 is operated.

In step 100, it is determined whether there is a cage in which no vehicle is stored. If there is no car in which a car is not stored, the notification means 20 is activated in step 102 to notify that the car is "full" and the process ends.

If there is a cage that has not been stored in the vehicle, it is determined in step 104 whether it is necessary to store the cage in consideration of weight balance. This determination is made by finding the number of blocks that do not contain vehicles in which all the cages in the blocks are non-vehicles. This is done by determining whether there are many. As an example, when the parking device 10 is in the state shown in FIG. 4, five blocks 61, 63.
Since 64, 66, and 69 correspond to blocks in which no vehicles are stored, the determination in step 104 is affirmative.

Further, when the parking apparatus 10 is in the state shown in FIG. 5, only three blocks 63, 68, and 70 correspond to the blocks in which no vehicles are stored, and the determination in step 104 is negative.

If the determination in step 104 is affirmative, it is determined that it is necessary to store the vehicle in consideration of the weight balance, and in steps 106 to 114, the vehicle is stored in consideration of the weight balance.
Store vehicles in blocks.

That is, in step 106, the parking device 10 is moved in the forward direction (
When the cage is rotated in the direction of the arrow in FIG. 1), the moving distance for the cage that constitutes the non-vehicle storage block and is closest to the landing position to move to the landing position is calculated. For example, in FIG. 4, the cage 32 corresponds, and the moving distance (two cages moved) is calculated.

Next, in step 108, when the parking device 10 is rotated in the opposite direction (in the direction of arrow B in FIG. 1), the cage forming the non-vehicle storage block and closest to the landing position moves to the landing position. Calculate the distance traveled. For example, in FIG. 4, the cage 49 corresponds, and the moving distance (9 cages moved) is calculated.

In step 110, step 106 and step 108
The moving distances determined in are compared, and it is determined whether the moving distance when moving in the forward direction is smaller than the moving distance when moving in the opposite direction. If the determination in step 110 is affirmative, in step 112 the parking device 10 is
Rotate in the positive direction by the travel distance determined in step 6. If the determination in step 110 is negative, in step 114 the parking device 10 is rotated in the opposite direction by the moving distance determined in step 108. For example, in FIG. 4, the moving distance of the cage 32 is shorter than the moving distance of the cage 49, so the determination in step 110 is affirmative, and in step 112, the parking device I
Move O by two positions in the forward direction.

As a result, the cage that constitutes the non-vehicle storage block and is closest to the landing position is moved to the landing position, allowing the vehicle to be stored. In addition, since vehicles are stored in blocks where no vehicles are stored, the parking device 1
0's weight balance will not collapse.

Further, if the determination in step 104 is negative, it is determined that although not all the blocks have vehicles stored, it is negligible in terms of weight balance, and in steps 116 to 126, the car calling time is taken into consideration. Store the vehicle.

That is, in step 116, when the parking device 10 is rotated in the forward direction, the distance traveled by which the cage that does not contain a vehicle and is closest to the landing position is moved to the landing position is calculated. For example, in FIG. 5, the cage 33 corresponds, and the moving distance (one for three cages) is calculated. In step 118, when the parking device 10 is rotated in the opposite direction, a moving distance is calculated for the cage that does not contain a vehicle and is closest to the landing position to move to the landing position. For example, in FIG.
is applicable, and the moving distance (4 digits) is calculated.

In step 120, step 116 and step 11
Compare the travel distances obtained in step 8. If it is determined that the moving distance in the forward direction is smaller than the moving distance in the reverse direction, the parking device 10 is rotated in the forward direction by the moving distance determined in step 116 in step 122. If it is determined in step 120 that the moving distance in the reverse direction is smaller than the moving distance in the forward direction, then in step 124 the parking device 10 is rotated in the opposite direction by the moving distance determined in step 118.

For example, in FIG. 5, the moving distance of the cage 33 is
Since the moving distance is shorter than the moving distance, the determination in step 120 is affirmative, and in step 122, the parking device 10 is moved in the forward direction by three spaces.

As a result, the cage in which no vehicle is stored and which is closest to the landing position is moved to the landing position, allowing the vehicle to be stored.

Further, if it is determined in step 120 that the moving distance in the forward direction and the moving distance in the reverse direction are equal, the process moves to step 126, and it is determined whether or not there are consecutive cages in which no vehicles are stored in the opposite direction of the parking device 10. Determine. Although this determination is not directly related to shortening the car calling time, it is performed in consideration of the weight balance of the parking device 10. If the determination in step 126 is affirmative, the parking device 10 is rotated in the opposite direction in step 124. Further, if the determination in step 126 is negative, the parking device 10 is rotated in the forward direction in step 122. For example, if it is assumed in FIG. 5 that no vehicle is stored in the cage 55, the determination in step 126 will be affirmative, and the parking device 10 will be rotated in the opposite direction in step 124.

Next, with reference to FIG. 6, the amount of rotation (traveling distance) of the parking device 10 when the conventional vehicle storage control method and the vehicle storage control method of the present invention are applied to the parking device 10 of this embodiment. Compare. Note that FIG. 6(A) shows the conventional
Figure (B) shows the present invention, and the numbers inside circles indicate the order of movement to the landing position. As shown in FIG. 6, in the present invention, control is performed in consideration of cage calling time from an earlier stage than in the past (from the 11th onwards), so the moving distance is smaller than in the past.

As described above, in this embodiment, the 28 cages 30 to 57 are divided into 14 blocks 60 to 73 including two cages, the number of blocks that can be ignored in terms of weight balance is set to "3", and the blocks not stored in the vehicle are Store a vehicle in one of the cages in each block while the number of blocks is greater than the number of blocks that can ignore weight balance, and after the number of blocks that do not store vehicles becomes less than the number of blocks that can ignore weight balance, the minimum time Since the vehicle is controlled to be stored in the cage that can be moved to the landing position, the average time for calling the cage can be further shortened, and the amount of rotation of the parking device 10 can be reduced.

In addition, in this embodiment, even if the number of blocks that are not stored in a vehicle is greater than the number of blocks that can ignore the weight balance, a cage with a short travel distance to the landing position is selected and moved, so that it is difficult for vehicles to move in and out. In actual use, which occurs randomly, the car calling time is significantly shortened and the amount of rotation is reduced compared to the conventional method.

Note that in this embodiment, one block was composed of two cages, but the present invention is not limited to this, and one block can also be composed of three or more cages. .

In addition, in this example, the number of blocks that can be ignored in terms of weight balance is determined by the following formula, and is 4 ・ nl
4 ・ Z = 3.25 The number of blocks was set as "3" as an integer that does not exceed the value calculated by the above formula, but when using the above formula, any integer that does not exceed the value calculated by the above formula is sufficient. For example, by adopting a value of 2 or less as the number of blocks that can be ignored in terms of weight balance, control may be performed with greater emphasis on weight balance.

Further, in this embodiment, an even number of cages has been described, but an odd number of cages may also be used. In the case of an odd number of cages, nl of the above-mentioned 0 formula becomes 1.

〔Effect of the invention〕

As explained above, in the present invention, as long as the number of blocks storing vehicles is smaller than the difference obtained by subtracting the number of blocks from the total number of blocks, a vehicle is stored in one of the cages of each block, and the vehicle is not stored. After the number of blocks entered is equal to the difference obtained by subtracting the number of blocks from the total number of blocks, the vehicle is stored in a cage that can be moved to the landing position in the shortest possible time, so the average time for calling the cage is It has the excellent effect that it can be further shortened and the amount of rotation of the parking device can be reduced.
