Description

  The present invention relates to an elevator group management control device that efficiently manages and controls transportation in a plurality of elevators.

  In a conventional elevator group management control device, call allocation control is one of group management controls performed when a plurality of elevators are installed. The call assignment control is to determine an assigned car to be answered by selecting and assigning a car to be serviced to the hall call as soon as the hall call is registered. By appropriately performing this call assignment, the transportation efficiency of a plurality of elevators installed in a building or the like can be improved.

  In addition, there is a system that registers a hall call at a certain distance from the hall, and a system that registers a hall call. For example, a device that can register a hall call at the entrance of a hall, From the above viewpoint, there is a system in which a card reader or the like is provided at the entrance of a condominium, and when a card reader is used, a call is registered and called to an elevator.

  When a device capable of registering a hall call at a remote location as described above is installed, it is necessary to consider the walking time of the user from the call registration device to just before the elevator. For example, if there is an elevator that is open, passengers who are already at the landing can get on immediately, but the elevator closes when a predetermined time has elapsed, so that passengers who register calls at remote locations may not be in time.

  In order to exclude such a situation from being avoided, a car whose expected arrival time is earlier than the walking time of the user from the call registration device to immediately before the elevator is excluded from the car assignment or the call registration device. There is a technique to call a car according to the walking time of the user from to the elevator. Further, according to Japanese Patent Application Publication No. 11-322205, for a plurality of elevators, the larger of the walking time to each elevator and the estimated arrival time of the car is the overall evaluation value of each elevator. A technique for selecting the minimum value from the overall evaluation values of all elevators is described.

Japanese Patent Application Publication No. JP-A-11-322205

  According to the technique described in Patent Document 1, all cars are not excluded from the assignment of cars to cars whose expected arrival time is earlier than the walking time of the user from the call registration device to immediately before the elevator. The situation of not being selected has been resolved.

  However, since the larger of the walking time to each elevator and the estimated arrival time of the car is the overall evaluation value of each elevator, the elevator arrival time is more than the walking time to the elevator for all the cars. Since the result is all the same on the comprehensive evaluation value when there is an early time, an arbitrary elevator may be selected. Then, in high-rise buildings where multiple cars are in service, it may be more efficient to arrive at an elevator near the registered floor and wait for the door to open, but it was arbitrarily selected. The elevator has a problem that the arrival time of the car may be significantly delayed from the walking time to the elevator due to calls to many other floors.

  The present invention is for solving the above-described problems. When the hall call registration device is located away from the hall, the car is considered in consideration of the walking time of the user and the number of elevator floors. An object is to provide an elevator group management control device to be selected.

In the present invention, when a hall call is registered from a landing button or a call registration means separated from the hall, a walking time estimation means for estimating a walking time for a passenger to reach the hall, and a plurality of cars can arrive at the hall Prediction operation means for predicting and calculating time, and actual waiting time obtained by subtracting the estimated walking time from the estimated arrival time of each of the cars predicted and calculated by the prediction calculating means , or arrival of each car from the walking time A waiting time conversion means for converting each into a loss time obtained by subtracting the predicted time, and the actual waiting time or the loss time converted by the waiting time conversion means, respectively , to increase the actual waiting time or the loss time. an evaluation value calculating means for calculating an evaluation value with an increase respectively, said substantially waiting time and when the loss computed the plurality of cars of the evaluation value calculating means And assigning means for determining a car with the minimum evaluation value among the evaluation values as assigned car based on the operation control means for instructing to move to the floor where the call to the car assigned registered, the Door opening / closing means that does not close the door until the estimated walking time elapses after the assigned car door is opened based on the actual waiting time or the loss time; The evaluation value accompanying the increase in the actual waiting time is made smaller than the inclination of the evaluation value accompanying the increase in the loss time, and the evaluation value accompanying the increase in the actual waiting time calculated by the evaluation value calculating means is the evaluation. It is characterized by being made lower than the evaluation value accompanying the increase in the loss time calculated by the value calculating means .

  According to such an emergency stop device for an elevator, when a hall call is registered from a call registration means separated from the hall button or the hall, there are a plurality of walking time estimation means for estimating the walking time for the passenger to reach the hall, Prediction calculation means for predicting and calculating the time at which the car can arrive at the landing, and waiting time for conversion into actual waiting time or loss time based on the difference between the estimated arrival time of the car predicted by the prediction calculation means and the estimated walking time. Using the time conversion means, the evaluation value calculating means for calculating an evaluation value that increases as the actual waiting time or the loss time increases, and the evaluation value calculating means Assigning means for determining the car having the smallest evaluation value as the assigned car, and operation control means for instructing the assigned car to move to the floor where the call is registered. Door opening / closing means that does not close the door until the estimated walking time elapses after the assigned car door is opened based on the substantial waiting time or the loss time. Since the hall call registration device includes a place away from the hall, the car is selected in consideration of the walking time of the user and the number of elevator floors, so that it can be called in a high-rise building where multiple cars are in service. Elevator group management control with high transport efficiency can be performed by arriving an elevator that can arrive at the arrival time more reliably with respect to the registered floor and opening the door.

Has been.

  The elevator group management control device 1 is also communicably connected to call registration means 7 installed at a position away from the landing. This call registration means 7 may be the same as the hall button 5 but can detect the arrival of passengers such as a card reader and a security gate and can transmit information to the elevator group management control device 1 as a hall call. If it is.

The interior of the elevator group management control device 1 will be described.
The elevator group management control device 1 includes communication means 8 that enables communication with each vehicle control means 3, landing guide control means 4, and call registration means 7.

  The elevator group management control device 1 includes a walking time estimation unit 9 that estimates a walking time until a passenger arrives at the landing when a call is registered from the landing button 5 or the call registration unit 7, and each car 2. When assigned to a new hall call, the prediction calculation means 10 that performs a prediction calculation such as how many seconds each car 2 can arrive, and the prediction of the walking time and the prediction calculation means 10 as an estimation result of the walking time estimation time 9 The waiting time conversion means 11 that compares the calculation results with each other and converts the predicted waiting time into a real waiting time or a loss time, and the evaluation value of each car for a new hall call based on the calculation results of the waiting time conversion means 11 The evaluation value calculation means 12 to be calculated, the assignment means 13 for determining the car 2 to be assigned based on the evaluation value of each car, and the door opening time when the assigned car 2 responds to the hall call A door opening and closing means 14 for determining, based on such determination of allocating means 13 and door opening and closing means 14, and a driving control unit 15 that controls the operation of the each car 2. Each component in the elevator group management control apparatus 1 is connected to be communicable with each other, and can exchange information.

The operation will be described.
FIG. 2 is a flowchart showing the operation of the elevator group management control apparatus according to the first embodiment of the present invention.
In step 100, when a call is registered from the hall button 5 or the call registration means 7, call registration information at least included in the floor information of the registered hall button 5 and the call registration means 7 and desired vertical movement information. Is input to the walking time estimation time 9 and the prediction calculation means 10 via the communication means 8 in the elevator group management control device 1.

  Next, in step 101, the prediction calculation means 10, based on the registration information of the call, out of N cars (N is a natural number of 2 or more), the car of the I-th car (I is a natural number of 1 to N), Prediction calculation of arrival time to reach the floor where call registration information is registered. The prediction calculation procedure has been widely implemented as group management control as shown in the method described in Japanese Patent Laid-Open Publication No. 54-102745.

  Next, in step 102, the walking time estimating means 9 first estimates the time required for the passenger who has registered for call to walk to the front of the car 2 at the landing. For example, the estimation of the walking time can be obtained by calculating a value obtained by dividing the distance from the position of the registered hall button 5 or call registration means 7 to the hall by the walking speed of the passenger. That is, walking time = distance to landing / walking speed. The distance to the landing is a value stored in advance by the walking time estimation unit 9 based on the call registration information, and the walking speed is also a value stored in advance by the walking time estimation unit 9. Since it is 4 km / h, it may be set as such. Therefore, the walking time estimation means 9 can store the walking time based on the call registration information in advance. In addition, when a call is registered by the landing button 5 before landing, the distance to the landing or the walking time stored in the walking time estimation means 9 may be zero.

  Next, the walking time estimating means 9 outputs the estimated walking time to the waiting time converting means 11, and outputs the arrival time for each car predicted and calculated by the prediction calculating means 10 to the waiting time converting means 11. . The waiting time conversion means 11 compares the arrival time for each car against the estimated walking time. Specifically, it is determined whether the arrival time for each car is large with respect to the estimated walking time.

  If the estimated walking time is shorter, in S103, the waiting time conversion means 11 changes the arrival time for each car to the actual waiting time. The actual waiting time is obtained by the actual waiting time = arrival time of each car−walking time. The difference between the arrival time of each car and the walking time is the difference between the actual waiting time and the walking time. I have to. The waiting time conversion unit 11 outputs the actual waiting time to the evaluation value calculation unit 12.

  If the estimated walking time is longer, in S104, the waiting time conversion means 11 calculates a loss time for each car. The loss time is a time in which each car cannot stop because it cannot operate, and is calculated by loss time = walking time−arrival time of each car. The waiting time conversion unit 11 outputs the actual waiting time to the evaluation value calculation unit 12.

  In S105, the evaluation value calculation means 12 performs evaluation value calculation based on the substantial waiting time in S103 and the loss time in S104. For example, the evaluation value is expressed by equation (1).

  FIG. 3 is a diagram illustrating an evaluation value with respect to a time when the evaluation value calculation unit 12 of the elevator group management control device according to the first embodiment of the present invention performs the evaluation value calculation. 3A, the vertical axis shows the evaluation value J1, the horizontal axis shows only the actual waiting time, FIG. 3B shows the evaluation value J2, the horizontal axis shows only the loss time, and FIG. In c), the vertical axis represents the evaluation value, and the horizontal axis represents the case where the actual waiting time and the loss time are combined.

The evaluation value for the actual waiting time obtained in S103 in FIG. 2 is FIG. 3A, but the obtained evaluation value J1 increases as the actual waiting time increases, and the evaluation value. The slope of J1 is also increased. The reason is that the greater the waiting time, the greater the passenger dissatisfaction.
In addition, the evaluation value J1 is multiplied by the weight wi, which is the weight of the passenger already on the Unit I, as the coefficient, so there are many passengers, so there is a high probability of getting on and off at another floor, Considering that the arrival time is delayed accordingly, the weight wi is used as a coefficient. Accordingly, it is possible to prevent a decrease in elevator transportation efficiency.

The evaluation value for the loss time obtained in S104 in FIG. 2 is FIG. 3B, but the obtained evaluation value J2 increases as the loss time increases, and the evaluation value J2 The slope is also getting bigger. The reason is to consider that the transport efficiency of the elevator is drastically decreased as the loss time is increased, and the decrease in the transport efficiency of the elevator can be prevented.
In addition, the evaluation value J2 is multiplied by the weight wi, which is the weight of the passenger already on Unit I, as the coefficient, so there are many passengers, so there is a high probability of getting on and off at another floor, Considering that the arrival time is delayed accordingly, the weight wi is used as a coefficient. Accordingly, it is possible to prevent a decrease in elevator transportation efficiency.
When the evaluation value J1 in FIG. 3A is compared with the evaluation value J2 in FIG. 3B, the evaluation value J2 has a larger slope with respect to time as a whole. This is an evaluation value that makes passengers wait at the landing in order to take into account that the transport efficiency of the entire car 2 is reduced when the car 2 of the Unit I is stopped rather than having the passengers again. The value of J1 is lowered overall.

  Note that the evaluation value J3 in FIG. 3C is the sum of the evaluation value J1 in FIG. 3A and the evaluation value J2 in FIG. By using such a function, evaluation can be performed without distinguishing between the substantial waiting time and the loss time in S103 and S104.

In S106, it is confirmed whether the allocation means 13 has been performed for each car No. 1 to No. N. If not, the steps from S101 to S105 are performed for the next car, and if completed, the process goes to S107. Then, the assigned car is determined by selecting the car of the No. I car having the smallest evaluation value J1 and J2 or J3. Finally, in S108, the assigning means 13 issues an assignment command to the assigned car 2.

For the assigned car 2, the operation control means 15 assigns the assigned car 2 based on the waiting time or loss time of the assigned car 2 stored in the waiting time converting means 11 or the evaluation value calculating means 12. Control the operation of.
FIG. 4 is a flowchart of control for the assigned car 2 performed by the operation control means 14 of the elevator group management control apparatus according to the first embodiment of the present invention.

  First, in S200, the operation control means 15 instructs the assigned car 2 to operate up to the floor where the call registration is made. Control of the position or speed of the assigned car 2 is performed by each of the vehicle control means 3 transmitted via the communication means 8. When the car 2 arrives, the door opening / closing means 14 outputs a door opening instruction, and each of the table control means 3 transmitted via the communication means 8 controls the position or speed of the door. Then, the door is opened.

  Next, in S201, the door opening / closing means 14 confirms whether or not the walking time of the passenger has elapsed since the landing call is registered. If it has passed, the door opening / closing means 14 instructs the communication means 8 to close the door in S202. Each table control means 3 transmitted through the door controls the position or speed of the door. If the walking time of the passenger has not elapsed since the landing call was registered, an instruction is given to maintain the door open state in S203. This is repeated every predetermined time. S203 is for preventing the door from closing and moving to another floor when the walking time of the passenger has not elapsed since the hall call was registered.

  Therefore, according to the first embodiment, when the hall call is registered from the hall button 5 or the call registration means 7 separated from the hall, the walking time estimation means 9 for estimating the walking time for the passenger to reach the hall, Prediction calculation means 10 for predicting and calculating the time at which each car 2 can arrive at the landing, and the actual waiting time or loss time based on the difference between the estimated arrival time of the car 2 predicted by the prediction calculation means 10 and the estimated walking time A waiting time conversion means 11 for converting to an evaluation value, an evaluation value calculating means 12 for calculating an evaluation value that increases with an increase in the actual waiting time or the loss time, and an evaluation value calculating means 12 An assigning means 13 for determining a car having the smallest calculated evaluation value as an assigned car, an operation control means 15 for instructing the assigned car 2 to move to a floor where a call is registered, and a substantial waiting time. After the door of the assigned car 2 is opened based on the interval or loss time, the door opening / closing means 14 that does not close the door until the estimated walking time elapses is provided. When the registration device includes a place away from the landing, by selecting the car in consideration of the user's walking time and the number of elevator floors, it is more suitable for the floor registered and called in a high-rise building where multiple cars are in service. Elevator group management control with high transport efficiency can be performed by arriving an elevator that can surely arrive at the arrival time and opening the door.

It should be noted that an evaluation value that increases from the reference time when the actual waiting time or loss time is 0 is used as a reference, and the minimum value of the evaluation value of each car is assigned, thereby reducing the loss time as in the conventional case. In the case of the case, as shown in Japanese Patent Application Publication No. 11-322205, the larger of the walking time to each elevator and the expected arrival time of the car When using the overall evaluation value of the elevator, if the arrival time of the elevator is earlier than the walking time to the elevator for all the cars, the overall evaluation value is the same, so any elevator is selected However, in high-rise buildings where multiple cars are in service, it may be more efficient to wait for the doors to open with an elevator near the registered floor. The arbitrarily selected elevator can also solve the problem that the arrival time of the car may be significantly delayed from the walking time to the elevator due to calls to many other floors.

  The elevator group management control device according to the present invention is suitable for elevator operation.
