DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control device.

[0002]

2. Description of the Related Art In general, a relatively large building is provided with a plurality of elevators in order to improve the passenger transportation capacity by elevators, and a car which can be arrived in the shortest time by a group management control device when registering a call at the landing. In most cases, such a system is selected as the most suitable car for the passenger, and a system for allocating the car to the corresponding floor is introduced. However, as the size of the building increases, the number of elevator cars installed increases and the number of elevator halls also increases. Increasing the number of elevator cars increases the transportation capacity, which has the advantage of shortening the waiting time in the elevator hall and improving service to passengers.On the other hand, when the elevator hall is wide, elevators that must respond to hall calls If it is farther away than the waiter's position in the elevator hall, it will not be noticed when it arrives, or if it arrives late and arrives in front of the elevator, the door is already closed It cannot be denied that the elevator will be difficult to use. Therefore, there is a technology in which a plurality of hall call registration buttons are installed in an elevator hall, and an elevator car close to the hall button pressed by the user responds preferentially.

For example, in the technique disclosed in Japanese Patent Application Laid-Open No. Hei 6-298466, when there are a plurality of cars waiting for doors to close on a floor where a hall call is registered, a hall button pressed by a user is called. Is given priority to the standby car located closest to the position. As a result, the user can get into the elevator car without moving unnecessarily in the elevator hall. Further, Japanese Unexamined Patent Publication No.
According to the technology disclosed in Japanese Patent No. 322205, in selecting an elevator for a hall call, in addition to evaluating the time required for the elevator to reach the corresponding floor, a user who presses the hall button can move each car from the position of the button. The time required to move to the position is added to the evaluation items.

[0004]

As described above, the conventional elevator group management control device performs an evaluation including a priority if a car close to the hall button is present when a hall call registration occurs. However, even if a standby car exists on the floor, the car is not necessarily a car that is close to the pressed landing button. Therefore, depending on the position of the car,
There is a problem that the effect of the control for giving priority to the car near the landing button cannot be sufficiently achieved.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and statistics of the number of times each button is pressed on each floor are taken, and the number of times the button is pressed when the car is on standby on the corresponding floor is obtained. By controlling the arrangement of the car closest to the most frequent hall button, the frequency of responding to the car near the customer's location is increased, and the burden of moving the customer and the burden of searching for a response car is reduced. The purpose is to improve services.

[0006]

According to the present invention, a hall call registering means for registering hall call button information in response to a call of a hall call button, and a car allocating means for allocating an elevator car to respond to the hall call. A landing button press detecting means for detecting the hall call button information registered in the hall call registering means for each hall call button, and a floor call button information from the hall button pressing detecting means for each floor. A landing button press frequency statistical means for accumulating a statistical result of the hall call button press frequency, and an elevator car close to the hall button with the largest number of floor button presses based on the statistical result accumulated by the hall button press frequency statistical means. And a waiting designated car evaluating means for evaluating a car to be dispatched and put on standby with priority, and the car allocating means assigns the car designated by the waiting designated car evaluating means to a corresponding floor. It is intended to be assigned to.

The present invention further comprises a time recognizing means for recognizing a current time, wherein the hall button pressing number statistical means receives time information from the time recognizing means, thereby receiving the hall call button pressing number for each floor. The standby designated car evaluating means accumulates the statistical result of the elevator car close to the hall button with the largest number of times of pressing the hall button based on the statistical result corresponding to the current time. This is to evaluate the cars to be dispatched and put on standby.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIG. 1 is a schematic configuration diagram showing an elevator group management control device according to Embodiment 1 of the present invention. In the figure, 1-1 is a hall call registration means, 1-2 is a car allocating means, 1-3 is a designated car evaluation means for standby, 1-4 is a hall button pressing frequency statistics means, and 1-5 is a hall button pressing detecting means. , 1-6 indicate current time detecting means. When a hall call button is pressed at the elevator hall on each floor, a hall call is registered by the hall call registration means 1-1. The generated hall call registration information is transmitted to the car allocating means 1-2, and in the elevator system provided with a plurality of cars, a car which responds to the hall call is selected and made to respond to the hall call. Also,
The registered hall call information is input to the hall button press detection means 1-5.
As a result, the information is transmitted to the landing button press count statistical means 1-4 as information for each installation button. Here, the number of times the hall button is pressed by the hall call button for each floor is statistic. When the dispatching operation of the waiting car to a certain floor is performed, the landing button press count statistics means 1
-4, the statistical result of the number of presses of each hall button on the corresponding floor is transmitted to the standby designated car evaluation means 1-3, and the number of presses is the largest depending on the relationship between the preset hall button and the proximity car. After taking out the car close to the landing button, taking into account the statistical evaluation value of the number of presses according to the statistical result of the number of presses to the evaluation value of the car, the car to be dispatched to the corresponding floor and to be on standby is determined.

In general, an elevator group management control device counts evaluation values based on the current position of a car, control conditions, and the like in order to specify a control target of each car. In the first embodiment, this evaluation value is a waiting time evaluation value specified based on the time required to move from each car position to the floor to be waited for, and is assigned to a car that is in a state of energy saving suspension or a car that has been started many times. Quota evaluation value to limit the number of floors that can be serviced when the service floor is different for each car, and allocation priority evaluation value to give priority to the car with the largest number of serviceable floors. The car position evaluation value indicating the effect on the service on the other floor is used as an evaluation value, and each car is given a comprehensive evaluation value that takes into account the number of pressing times statistical evaluation value according to the number of pressing times statistical result. I have.

The above-described overall evaluation value is merely an example, and the weighting of each evaluation value does not need to be equivalent. Further, if the weight of the statistical evaluation value of the number of times of pressing is increased, it is canceled by other evaluation values. The case goes down.

Further, by providing the current time detecting means 1-6, the current time is grasped, and when the number of times of landing button presses is to be statistically transmitted, time information is transmitted to the landing button number of times statistical means 1-4. Statistical processing of the number of times the hall button is pressed can also be performed for each designated time zone. The time information is also transmitted to the standby designated car evaluation means 1-3 for evaluating the standby car, and when carrying out the dispatching operation of the standby car to the specific floor, the statistical result of the time zone including the acquired current time is obtained. It is obtained from the landing button press count statistics means 1-4.

FIG. 2 schematically shows an example of an elevator system to which the first embodiment is applied.
This shows the positional relationship between an elevator car and a hall call registration button on a certain floor, where 1 is an elevator hall, 2 is a car (a), 3 is a car (b), 4 is a car (c), 5 The car (d), 6 is a hall lantern for notifying the waiting car in the elevator hall 1 of the assigned car or the arrival car, 7 is a hall call registration button (A), 8 is a hall call registration button (B), and 9 is a hall call. The registration button (C) is shown. In the first embodiment, a total of three hall call registration buttons are provided, one for each of the four cars. Note that the hall lantern 6 is not installed in some buildings, and instead, a hall indicator indicating the position information of each car may be added.

FIG. 3 shows an example in which a car adjacent to each hall call registration button is set based on the example of FIG. Embodiment 1
Since the hall buttons are installed between the two cars, there are two cars adjacent to each hall button. That is, the button and the adjacent car do not always have a one-to-one relationship. Therefore, the proximity car of button A is car 1
And car 2, the proximity car of button B is car 2 and car 3, button C
Are the cars 3 and 4. The setting information here is referred to by the standby designated car evaluation means 1-3 in FIG. This setting is only one pattern, but the relationship between the button symbol and the car number may be different depending on the floor. In this case, it is only necessary to have the setting information of FIG. 3 for each floor.

FIG. 4 shows the landing button pressing frequency statistics means 1 of FIG.
4 is an example showing a storage form of data statistically obtained in FIG. In this example, in a seven-floor building, the number of hall buttons provided on each floor is three, and statistical data of the number of times the hall buttons are pressed is stored for each floor. When a button is pressed by a customer at each floor and each landing button, the fact that the button is pressed is detected by the landing button pressing detection means 1-5 in FIG. 1, and the statistics of the corresponding floor and the corresponding landing button are counted up. You. In this example, the past 1
Although the results for hours are stored, the length of time may be stored for one day if the number of hall call registrations is small or if the tendency of the buttons to be pressed does not change throughout the day. .

FIG. 5 is a flowchart showing the operation of the car allocating means in the elevator group management control device according to the first embodiment. In 5-1, a standby car request is automatically generated when the standby car is absent by pre-registering the standby designated car evaluation means in FIG. 1 so as to secure the standby car on the specific floor. Set it. If the allocation request is NO in 5-1, the process ends, and if it is YES, the process proceeds to 5-2. 5
In -2, the landing button press count statistics means 1-4 refers to the result of the landing button press count statistics on the floor where the waiting car is requested, and the process proceeds to 5-3. In 5-3, based on the statistical result obtained in 5-2, a car close to the button that is pressed many times is extracted as a standby designated car candidate, and the process proceeds to 5-4. 5-
In step 4, the button press count evaluation value is added to the standby designated candidate extracted in step 5-3 so that the car can be easily selected as a standby car. In 5-5, a car to be assigned as a standby car is selected from all the cars including the standby designated car candidate in which the button press count evaluation value is added, based on the evaluation value calculation, and the process proceeds to 5-6. At 5-6, an instruction is transmitted to the finally selected car to wait on the corresponding floor.

Embodiment 2 FIG. FIG. 6 is a flowchart showing the operation of the car allocating means in the elevator group management control device according to the second embodiment. In the first embodiment, processing is performed so that a car close to the landing button is easily selected as a standby car by taking into account an evaluation value according to the number of times the button is pressed. Instead of selecting from the car, a method of unconditionally selecting a nearby car as a standby car is also conceivable. FIG. 6 shows the flow of the processing. In 6-1, it is determined whether or not there is a request to wait for a car to a specific floor. Here, a car standby operation in a quiet or normal time and a car dispatch operation to a specific floor when the specific floor is congested are requested. Then, it is determined that "there is a request" in the process of 6-1. When there is a request, the process proceeds to 6-2, and when there is no request, the process ends. In step 6-2, the process proceeds to step 6-3 with reference to the landing button press count statistical result on the floor where the waiting car is requested from the hall button press count statistical means 1-4 in FIG. In step 6-3, a car close to the button that is pressed many times is extracted based on the statistical result obtained in step 6-2, and the car is designated as a standby designated car candidate. At 6-4, it is determined whether the car extracted as a candidate can be on standby. For example, when a passenger is in a candidate car and is traveling to the destination floor of the passenger, or is traveling in response to a floor call registration of another floor, and cannot immediately wait for the corresponding floor If it is already on standby in response to a standby request on another floor, or if it is not in a state where general service can be performed, such as during maintenance and inspection, it is determined that standby is impossible, and in that case, the process proceeds to 6-5. 6-
If the candidate car can be waited at 4, the car is selected as the waiting car, and the process proceeds to 6-6. If there are a plurality of cars that are determined to be ready in 6-4, one of them is determined by evaluation value calculation from them.
At 6-5, a standby car is selected from the cars excluding the candidate car extracted at 6-3 by evaluation value calculation or the like, and the process proceeds to 6-6. At 6-6, an instruction is transmitted to the selected car to wait on the corresponding floor.

Embodiment 3 FIG. 7 is a diagram in which the statistical data of FIG. 4 described above is statistically classified by time zone in the elevator group management control device according to Embodiment 2 of the present invention.
The second embodiment is effective when the pattern of pressing the hall button changes in a time zone. The length of the time zone here may be similarly changed as needed. In addition, if the building has a feature that the pattern changes depending on the day, the time zone may be changed for each day of the week. It is not necessary that the intervals of the time zones are all the same, and a method of shortening the interval in a time zone in which the pattern changes drastically and lengthening the interval in a time zone with little change is conceivable.

FIG. 8 is a flow chart showing the operation of the car allocating means in the elevator group management control device according to the third embodiment when the landing button pressing statistical processing is performed for each time zone. At 8-1, it is determined whether or not there is a request to wait for the car to a specific floor. Here, when a car standby operation during a quiet or normal time or a car dispatch operation to a specific floor during a specific floor congestion is requested, it is determined as “requested” in the process of 8-1. When there is a request, the process proceeds to 8-2, and when there is no request, the process ends. In step 8-2, the current time is detected. Subsequently, when the process proceeds to 8-3, the statistical result of the number of times the hall button is pressed on the floor where the waiting car is requested in the time zone including the current time detected in 8-2 is referred to. This corresponds to 1-4 in FIG.
This refers to referring to the data on the corresponding floor in the corresponding time zone among the statistical results shown in FIG. 7 obtained by performing the statistical processing by the landing button pressing number statistical means. Then proceed to 8-4, 9
Based on the statistical result obtained in step -3, a car close to the button that is pressed many times is taken out, and that car is designated as a standby designated car candidate. Proceeding to 8-5, a plus evaluation value is added to the waiting designated candidate car taken out in 8-4 so that it can be easily selected as a waiting car. In step 8-6, a car to be assigned as a standby car is selected from all the cars including the standby designated car candidate to which the plus evaluation value is added, based on the evaluation value calculation. Proceeding to 8-7, an instruction is transmitted to the finally selected car to wait on the corresponding floor.

Embodiment 4 FIG. 9 is a flowchart showing the operation of the car allocating means in the elevator group management control device according to the fourth embodiment, in which a car which has already been designated for standby in response to a standby operation request is depressed by a landing button on the corresponding floor. If the car is not the one closest to the landing button with the largest number of times, the waiting car is re-examined, that is, a candidate car designated for waiting is extracted again, and the designated car evaluating means 1-3 performs the evaluation process again. As a result, when the car in proximity to the hall button is selected as a standby car, a process of changing from the car which is initially on standby is performed. FIG. 9 will be described below. At 9-1, 0 is set to the internal variable fl. This variable is a count-up variable for a loop operation in which a value indicating a floor is substituted and a process of determining whether or not a waiting car exists on each floor from the lowest floor to the highest floor. Proceed to 9-2 and add 1 to the variable fl. In step 9-3, it is determined whether or not a standby car has been detected on each floor up to the top floor. If not, 9-
Proceed to 4. In 9-4, it is determined whether there is a car waiting on the fl floor in response to a request for a standby operation. If it does not exist, it returns to 9-2, and if it exists, it goes to 9-5. In 9-5, the statistical result of the number of times the landing button on the fl floor is pressed is acquired from the database shown in FIG. Proceeding to 9-6, car standby designated car candidates on the floor are extracted based on the data acquired in 9-5. The process proceeds to 9-7, and it is determined whether or not the standby designated candidate car extracted in 9-6 is equal to the car currently performing the standby operation. If they are equal, the process returns to 9-2; if they are not equal, the process proceeds to 9-8. In 9-8, the assignment of the waiting car is reviewed. The procedure is the same as that shown in FIG. As a result, when the standby designation candidate car is selected as the standby car, the standby car is changed to the newly selected car. Thereafter, the process proceeds to 9-2.

[0021]

Since the present invention is configured as described above, it has the following effects.

Based on the result of pre-stating the number of presses by the passenger for each hall button, control is performed such that a car close to the hall button with a large number of presses is preferentially dispatched to the corresponding floor, thereby achieving many uses. Since cars closer to the customer's position are preferentially dispatched and waited in advance, the frequency at which passengers can respond to cars that can be boarded without moving a long distance,
The service to the customer can be improved.

Further, by performing the statistics of the number of times the hall buttons are depressed for each predetermined time zone, even if the frequency of using the hall buttons varies depending on the time zone, an appropriate value can be set in accordance with the statistical result. A car can be dispatched.

If the car assigned to a certain floor is not a car close to the button with the largest number of presses of the landing button on the floor, the car to be dispatched and put on standby is evaluated again. Even if a car close to the button with the largest number of presses of the landing button on the corresponding floor is not selected in the allocation of the corresponding floor, it is possible to allocate and wait at the corresponding landing after that,
The convenience of the user can be further improved.
