Description

Elevator group management control device {ELEVATOR GROUP MANAGEMENT AND CONTROL DEVICE}

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

In the conventional elevator group management control apparatus, call allocation control is one of group management control to be performed when a plurality of elevators are provided together. Call allocation control is to determine which allocation car to respond to by selecting and assigning a car to be served to the landing call immediately after a landing 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 for registering a platform call at a certain distance from the platform and registering a platform call. For example, a device for registering a platform call at the entrance of the platform is provided. Examples of the installation include a system such as a card reader installed at the entrance of a mansion from a security point of view, and the card reader is used to register a call in an elevator to make a call.

As shown above, when a device capable of registering a platform call at a remote location is provided, it is necessary to consider the user's walking time from the call registration device to the front of the elevator. For example, if there is an elevator with a door open, passengers who are already in the platform can board immediately, but since the elevator is closed after a predetermined time, passengers who have registered a call from a remote location may be late.

In order to eliminate such a state, a car with an estimated arrival time earlier than the user walking time from the call registration device to the front of the elevator is excluded from the allocation of the car, or the user from the call registration device to the front of the elevator. There is a technique to call a car in accordance with the walking time. In addition, according to Japanese Patent Application Laid-open No. Hei 11-322205, a plurality of elevators are regarded as a comprehensive evaluation value of each elevator, with the larger one of the walking time to each elevator and the estimated time of arrival of the car being all. The technique which selects the minimum among the comprehensive evaluation values of an elevator is described.

Patent Document 1: Japanese Patent Application Laid-open No. Hei 11-322205

According to the technique described in Patent Literature 1, all cars are not selected because they are not excluded from the allocation of cars for cars that have an estimated time of arrival earlier than the user walking time from the call registration device to the front of the elevator. The situation is solved.

However, since the larger of the walking time to each elevator and the estimated arrival time of the car is made into the comprehensive evaluation value of each elevator, when the arrival time of the elevator is earlier than the walking time to the elevator for all the cars, Since the result is the same on all the comprehensive evaluation values, arbitrary elevators may be selected. Then, in a high-rise building in which a plurality of cars are commissioned, it may be more efficient to arrive at an elevator close to the floor where the call is registered, and to wait with the door open. There existed a problem that the arrival time of a compartment may be delayed considerably later than the walking time to an elevator.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides an elevator group management control device for selecting a car in consideration of a user's walking time or the number of floors of an elevator when the platform call registration device is located at a place away from the platform. It aims to do it.

The present invention provides a pedestrian time estimating means for estimating a pedestrian time for a passenger to reach a platform when the platform call is registered from a platform button or a call registration means away from the platform, and a time at which each car can arrive at the platform. Predictive calculating means for predicting a value, and waiting time converting means for converting a difference between the walking time estimated as the arrival predicted time of the car predicted by the predictive calculating means into a substantial waiting time or a loss time; An evaluation value calculating means for calculating an evaluation value which increases with the increase of the actual waiting time or the loss time using the substantial waiting time or the loss time, and the evaluation value calculated by the evaluation value calculating means. This minimum car is assigned as an assigned car Determining means for determining, operation control means for instructing the assigned car to move to the floor where a call is registered, and the door of the allocated car is opened based on the actual waiting time or the loss time. After that, the door is provided with an opening and closing means not to close the door until the estimated walking time has elapsed.

According to the emergency stop device of an elevator according to this, when the platform call is registered from the call registration means away from a platform button or a platform, the walking time estimation means which estimates the walking time which a passenger reaches to a platform, and each car which has many Prediction calculation means for predicting and calculating the time that can arrive at the platform, and waiting for converting the difference between the walking time estimated by the arrival prediction time of the car predicted by the prediction calculation means into a substantial waiting time or a loss time. A time conversion means, an evaluation value calculating means for calculating an evaluation value which increases with the increase of the actual waiting time or the loss time by using the substantial waiting time or the loss time, and the evaluation value calculating means As long as the above evaluation value is the minimum Assigning means for determining a car as an allocated car, driving control means for instructing the assigned car to move to a floor to which a call is registered, and based on the actual waiting time or the lost time, After the door of the car is opened, the door opening and closing means is not provided until the estimated walking time has elapsed, and thus the door call registration device includes a place away from the platform. By selecting a car in consideration of the walking time of a car and the number of floors of an elevator, a door that is more reliably arrived at an arrival time for a floor registered in a call in a high-rise building where a plurality of cars are commissioned is opened. Ellie with good carrying efficiency in the open state It may be subjected to the group management control of the data.

Are electrically connected to each other.

The elevator group management control device 1 is also communicatively connected to the call registration means 7 provided at a position away from the platform. The call registration means 7 may be the same as the boarding point button 5, but for example, a card reader, a security gate, or the like detects the arrival of a passenger and sends information to the elevator group management control device 1 as a boarding point call. It can be anything that can be delivered.

The inside of the elevator group management control apparatus 1 is demonstrated.

The elevator group management control apparatus 1 is provided with the communication means 8 which enables communication with each stand control means 3, the boarding point guide control means 4, and the call registration means 7. As shown in FIG.

Moreover, the elevator group management control apparatus 1 is a walk time estimation means 9 which estimates the walking time until a passenger arrives at a landing hall when a call is registered from the landing button 5 or the call registration means 7. ) And prediction calculation means 10 for performing prediction calculation that each car 2 can arrive after a few seconds when each car 2 is assigned to a new landing call, and a walking time estimation time.

Each component in the elevator group management control device 1 is connected so as to be communicable with each other, and information can be exchanged.

The operation will be described.

Fig. 2 is a flowchart showing the operation of the elevator group management control device of the first embodiment of the present invention.

In step 100, when a call is registered from the boarding point button 5 or the call registration means 7, at least it is included with respect to the floor of the registered landing button 5 or the call registration means 7 or the desired up-and-down movement information. The registration information of the call is input to the walking time estimation time 9 and the predictive calculating means 10 via the communication means 8 in the elevator group management control device 1.

Next, in step 101, the predictive calculating means 10 selects a car (I is a natural number of 1 to N) from among N (N is a natural number of 2 or more) cars based on the registration information of the call. For each step, a prediction operation of the arrival time for reaching the registered floor of the call registration information is performed. The procedure of the predictive calculation is conventionally widely implemented as group management control, as shown in the method described in Japanese Patent Laid-Open No. 54-102745.

Next, in step 102, first, the walking time estimating means 9 estimates the time required for the passenger who has registered the call to walk to the front of the car 2 of the landing. For example, the estimation of the walking time is obtained by calculating a value obtained by dividing the distance from the position of the registered landing button 5 or the call registration means 7 to the landing by the passenger's walking speed. That is, walking time = distance to a platform ÷ walking speed. The distance to the platform is based on the registration information of the call using the value previously stored by the walking time estimating means 9, and the walking speed is also used by using the value previously stored by the walking time estimating means 9, for example, Since the walking speed is 4 km / h, you may set it in this way. Therefore, it is also possible for the walking time estimation means 9 to store the walking time based on the registration information of the call in advance. In addition, when a call is registered by the boarding point button 5 in front of a boarding point, the distance to the boarding point memorized by the walking time estimation means 9, or the walking time may become O.

Next, the walking time estimating means 9 outputs the estimated walking time to the waiting time converting means 11, and calculates the arrival time for each car predicted by the predictive calculating means 10 by the waiting time converting means. Output to (11). The waiting time converting means 11 compares the arrival time for each car with respect to the estimated walking time. Specifically, it is determined whether the arrival time for each car is large for the estimated walking time.

If the estimated walking time is short, in S103, the waiting time converting means 11 changes the arrival time for each car to the actual waiting time. The actual waiting time is determined by the actual waiting time = the arrival time of each car-the driving time. The difference between the actual waiting time and the arrival time of each car and the walking time is that the difference is the actual waiting time because it is difficult to feel that passengers are waiting to perform an operation such as walking. The waiting time converting means 11 outputs the substantial waiting time to the evaluation value calculating means 12.

If the estimated walking time is long, in S104, the waiting time converting means 11 calculates a loss time for each car. Lost time is the time when each car cannot be operated and cannot be stopped. Loss time = walking time-the arrival time of each car. The waiting time converting means 11 outputs the substantial waiting time to the evaluation value calculating means 12.

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

[Equation 1]

J (I) = Σwifi (xi)

J (I): Evaluation value at the time of allocation of unit I ... (1)

wi: weight

xi: actual wait time or loss time

3 is a diagram showing an evaluation value with respect to the time when the evaluation value calculating means 12 of the elevator group management control device of the first embodiment of the present invention performed the evaluation value calculation. 3 (a) shows the evaluation value J1, the horizontal axis shows only the substantial waiting time, and FIG. 3 (b) shows the evaluation value J2, the horizontal axis shows only the loss time, and FIG. 3 (c) shows the evaluation value, The abscissa represents the sum of the actual waiting time and the loss time.

Although the evaluation value with respect to the substantial waiting time calculated | required by S103 in FIG. 2 is FIG.3 (a), the evaluation value J1 calculated | required has become large, and the inclination of evaluation value J1 also becomes large as actual waiting time becomes large. The reason is that as the actual waiting time increases, passenger complaints also increase dramatically.

Multiplying the weight wi, which is the weight of the passenger already in Unit I, by the factor J1 evaluates that the probability of getting on and off the other floor is high, and the arrival time is late. In consideration, the weight wi is taken as a coefficient. The fall of the transportation efficiency of an elevator can be prevented by that much.

The evaluation value with respect to the loss time calculated | required by S104 in FIG. 2 is shown in FIG.3 (b), The evaluation value J2 calculated | required has become large, and also the inclination of evaluation value J2 becomes large as loss time becomes large. The reason for this is to consider that the transportation efficiency of the elevator drastically decreases as the loss time increases, and it is possible to prevent the reduction of the transportation efficiency of the elevator.

In addition, the evaluation value J2 multiplying the weight wi, which is the weight of the passenger already in Unit I by the coefficient, indicates that the passengers are more likely to climb to another floor, and the arrival time is late. In consideration, the weight wi is taken as a coefficient. The fall of the transportation efficiency of an elevator can be prevented by that much.

Moreover, when the evaluation value J1 in FIG.3 (a) is compared with the evaluation value J2 in FIG.3 (b), the inclination with respect to time as the evaluation value J2 generally becomes large. The value of evaluation value J1 which is a side which makes a passenger wait in a platform because the side which stops the cage | basket | car 2 of Unit I rather than having to wait for a passenger considers the transportation efficiency of the cage | basket | car 2 whole fall. Is lowering overall.

In addition, the evaluation value J3 of FIG. 3 (c) is the sum of the sum of the inverses of the loss time of the evaluation value J1 of FIG. 3 (a) and the evaluation value J2 of FIG. In particular, the evaluation can be performed even if the actual waiting time and the loss time are not distinguished in S103 or S104.

In S106, if the assigning means 13 confirms whether it was performed to each unit No. 1-N unit, if it was not done, it performs the steps to S101-S105 about the next car, and when it is finished, S107. The allocation car is determined by selecting the car of unit I which the evaluation values J1, J2, or J3 become the minimum. Finally, in S108, the allocating means 13 issues an allocating command to the allotted car 2.

For the assigned car 2, the operation control means 15 is based on the waiting time or the loss time of the assigned car 2 stored in the waiting time converting means 11 or the evaluation value calculating means 12. The operation of the assigned car 2 is controlled.

4 is a flowchart of control on the assigned car 2 executed by the operation control means 14 of the elevator group management control device of the first embodiment of the present invention.

First, in S200, the operation control means 15 instructs the operation | movement to the floor to which the call registration was made with respect to the allocation car 2. And control of the position or speed of the allocation car 2 is performed by each 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 stand control means 3 transmitted via the communication means 8 controls the position or speed of the door. The door is then opened.

Next, in S201, the door opening / closing means 14 confirms whether or not the passenger's walking time has elapsed since the landing call is registered, and if so, instructs the door to be closed in S202, via the communication means 8; Each transmitted control means 3 controls the position or speed of the door. If the passenger's walking time has not elapsed since the landing call was registered, the instruction in S203 is to keep the door open. This is repeated every predetermined time. S203 is for preventing the door from closing and moving to another floor when the passenger's walking time has not elapsed since the landing call is registered.

Therefore, according to Embodiment 1, when the landing call is registered from the landing button 5 or the call registration means 7 away from the landing, the walking time estimation means 9 which estimates the walking time which a passenger reaches to a landing. And the predictive computing means 10 for predicting and calculating the time at which each of the plurality of cars 2 can arrive at the landing, and the estimated predicted time of arrival of the car 2 predicted and calculated by the predictive computing means 10. A waiting time converting means 11 for converting the difference from the estimated walking time into a substantial waiting time or a loss time, and an evaluation value which increases with the substantial waiting time or loss time using the substantial waiting time or loss time. Is assigned as the assigned car by the evaluation value calculating means 12 which calculates the value, and the car whose minimum evaluation value which the evaluation value calculating means 12 calculated is minimum. Assigned means 13, operation control means 15 for instructing the assigned car 2 to move to the floor on which the call is registered, and the assigned car based on the actual waiting time or lost time. Since the door opening and closing means 14 which does not make the door closed until the estimated walking time elapses after the door of 2) has been opened, since the landing call registration device includes a place away from the landing, By selecting a car in consideration of the walking time of a car and the number of floors of an elevator, a door that is more reliably arrived at an arrival time for a floor registered in a call in a high-rise building where a plurality of cars are commissioned is opened. In an open state, group management control of an elevator with good transportation efficiency can be performed.

In addition, it is set as the evaluation value which increases from the criterion on the basis of when the actual waiting time or the loss time is 0, and the minimum value of the evaluation value of each car is made into the assigned car, As shown in Japanese Patent Application Laid-open No. Hei 11-322205, a case which is not subject to any evaluation, the larger of the walking time to each elevator and the estimated time of arrival of the car, the overall evaluation of each elevator. In the case of setting the value, when the arrival time of the elevator was earlier than the walking time to the elevator for all cars, all of them resulted in the same result on the comprehensive evaluation value, so that an arbitrary elevator was selected and a plurality of cars were commissioned. In high-rise buildings to say, Elibe close to the floor registered to call In some cases, it is efficient to wait for the door to be opened and wait for the door to be left open. However, when the elevator is arbitrarily selected, the arrival time of the car may be delayed by a large number than the walking time to the elevator. We can solve problem that we say.

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