Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator group management and control method for managing a plurality of elevator cars with uneven service floors as a group.

`` To the rod ■ Suichi + + pull - TLypi decoy purchaser yo 1 Conventionally,
In elevator groups that service multiple floors, each car usually serves the same floor.
For example, when there is a parking lot or a management room underground, the service floors of each car may be uneven for various reasons, such as only a specific car operating the underground floor.

In this way, in an elevator where multiple cars with uneven service floors are installed and managed as a group, only some cars can be serviced from the floor where all the cars can be serviced (hereinafter referred to as "common floor"). If a car that responds to a hall call cannot service the desired floor, a user going to a floor (hereinafter referred to as an uneven floor) must either wait until a car that services the uneven floor responds, or ride that car and return to the desired floor. There were inconveniences such as having to go near the desired floor before changing trains. For this reason, if only cars that can service uneven floors are assigned to hall calls, there would be no need for transfers, but not only would the waiting time be longer, but in reality, many customers would go to the common floor. Operation efficiency also deteriorates.

It is also possible to install hall buttons separately for different destinations, such as hall buttons for common floor services and hall buttons for services on uneven floors, but this would be expensive, or it would be a prank or a rush. There are problems such as passengers being unable to press both buttons.

[Means for solving the problems] The present invention was made to solve the above problems, and
When allocating a hall call, normal evaluation values such as waiting time are calculated for cars that can service uneven floors (hereinafter referred to as cars that can service uneven floors). For cars (hereinafter referred to as non-service cars with uneven floors), an evaluation value calculated by converting the rate of transition from the floor where a hall call occurred to a car call on an uneven floor is added to the normal evaluation value. has.

In other words, a floor with a high rate of transition from a floor where a hall call occurs to a car call on an uneven floor, that is, a floor with a high rate of passengers going to an uneven floor, is given a large evaluation value, and a floor with a high rate of passengers going to a common floor is given a high evaluation value. By adding a small evaluation value to the evaluation value of a non-service car on an uneven floor, it becomes difficult for a hall call to be assigned to a non-service car on an uneven floor on a floor where there is a high possibility that passengers will go to an uneven floor. It is.

[Example code] Hereinafter, one embodiment of the present invention will be described based on the drawings.

The figure shows the relationship between cars and calls for explaining the present invention.For convenience of explanation, four elevators, number 1 to Il&L4, are in service, and the first basement floor and the second basement floor are uneven floors. In Figure 0, which shows an example where only Units 1 and 2 can be serviced and the 1st to 6th floors are common floors, the car of N11l No. 1 is ascending the 2nd basement floor, while the car of No. 2 is descending from the 6th floor, the car of N113 is ascending from the 1st floor, and Omi No. 4 is descending from the 4th floor.

C11 is the first floor car call that was successfully registered in the car of No. 1, and C16 is the same <6 that was successfully registered in the car of No. N111.
The car call on the floor is also C22B.

C21 and C23 are the car names for the 2nd basement floor, 1st floor, and 3rd floor registered in the car of NnZ car, and C33 and C3.
5 is the car call on the 3rd and 5th floors registered in the car of No. 3, C41 is the car call on the 1st floor registered in the car of Arashi No. 4, and HD2 is the newly generated hall heading down to the 2nd floor. This assignment will be explained by calling.

First, the rate of transition from the hall call on each floor to the car call on an uneven floor, that is, the rate at which passengers who board a car from the landing on the departure floor press the car call button on an uneven floor, is determined in advance for each floor, and the transition rate is determined in advance for each floor. The rate is converted into a corresponding evaluation value and created as data in advance.

Here, in the case of transition from a hall call to a car call with uneven floors, only the descending direction needs to be considered, so only the descending direction will be described below.

Table 1 shows the floor of each floor (departure floor) and the corner of the landing (destination floor).
This is a calculation of whether the elevator will transition to a car call or not, only for cars that can be serviced on uneven floors after operating the elevator for a certain period of time. It shows that the number of times that the button was pressed was seven times, and the number of times that the car call button on the second basement floor was pressed was three times.

Table 1 Table 2 shows the transition rate calculated for each floor from Table 1.
For example, for the 6th floor, out of the 16 total car calls within a certain period of time, 5 were calls to uneven floors, so the transition rate is 0.31.

Table 2 be.

Table 3 From Tables 2 and 3, evaluation values corresponding to hall calls on each floor are stored in advance as fixed data and used for subsequent allocation calculations. For example, for a landing call in the direction of descending to the second floor, the transition rate for uneven floors is 0.8, so the evaluation value is 30, so this evaluation value of 30 is used in the allocation calculation as described later. It is added only to service cars, so that non-service cars with uneven floors are difficult to be assigned.

Note that the transition rate to uneven floors does not have to be determined by running the elevator as described above, but can be simply calculated by calculating the ratio of the number of uneven floors to the total number of floors that may transition from each hall call. You can also use it as For example, for a landing call going down to the 3rd floor, the number of floors that may change is a total of 4 floors from the 2nd floor to the 2nd basement, and the irregular numbers of floors are the 1st basement and the 2nd basement. Since this is the second floor, the transition rate to an irregular floor can be determined as 0.5.

Furthermore, since this transition rate actually changes depending on the day of the week or the time of day, the data in Table 1 may be collected at predetermined time intervals and updated each time.

Next, the assignment calculation will be explained.

In the figure, when it is assumed that a descending hall call HD2 on the second floor occurs, a normal evaluation value calculation is first performed for each car. Here, the expected waiting time for hall call HD2 is calculated as a normal evaluation value, and the result is No. 1.
Assume that the time was 50 seconds for Unit No. 2, 20 seconds for Arashi Unit 2, 40 seconds for NQa Unit, and 10 seconds for Nc Unit 4.

Next, since the evaluation value corresponding to the transition rate from the hall call HD2 to the uneven floor is stored as data as described above, this value is assigned to N1113, which is a non-service car with an uneven floor.
Add only to Unit No. 4. As mentioned above, here the transition rate from hall call HD2 to irregular floors is 0.
8, and the corresponding evaluation value is 30, so if this is added only to N113 and NQ Unit 4, the evaluation value of each unit is Arashi Unit 1 -50+ 0-5O N112 Unit -20+ 0-20 81113 Unit 140 + 30- 70 Arashi Unit 4■10+30 proverb 40. As a result, hall call HD2 is assigned to car No. N11g with the smallest evaluation value.

In other words, hall call HD2 should be assigned to NQ 4 considering only the waiting time, but since it is unclear whether passengers boarding from the second floor will go to the common floor or the uneven floor, passengers will Considering the rate of access to uneven floors, it was assigned to Arashi Unit 2, which can service uneven floors.

Note that the conversion of the transition rate into an evaluation value, that is, the weighting of the normal evaluation value, is not limited to the above example and can be arbitrarily determined.

[Effects of the Invention] According to the present invention, since the transition rate to an uneven floor is added to the conventional evaluation value as an evaluation value, the floor where there is a high possibility that passengers will go to an uneven floor is determined by which floor is available for uneven floor service. This makes it easier to allocate hall calls to customers, reducing the chance of having to change trains without deteriorating the overall efficiency or waiting time of the group, which has a significant effect on reducing the inconvenience for customers who prefer to use uneven floors. demonstrate.
