To achieve the foregoing, this elevator group control system controls the operation of multiple elevator cars, wherein the system comprises: a means for detecting the number of users present at an elevator landing on a prescribed floor; a means for detecting the number of riders inside elevator cars that are stopped with open doors at this prescribed floor; a means for calculating, on the basis of such number of users at the landing and such number of riders inside the cars, the number of elevator cars to be stopped with closed doors at the prescribed floor; and a means for opening the doors of any elevator cars that are stopped with closed doors at this prescribed floor.

Description

Elevator group management system

The present invention relates to an elevator group management system that manages and manages a plurality of elevators.

The elevator system is a vertical transportation system in a building, and in a particularly large building, it is composed of a system consisting of multiple elevators and an elevator group management that manages them as a group. The purpose of such an elevator system is to transport as many users as possible per predetermined time to the destination floor, and this is particularly important during busy hours such as when going to work or lunch.

For example, the technique described in Patent Document 1 describes an example of control in which the number of waiting passengers on a specific floor is detected, and the next door opening waiting car is selected as the next door opening waiting car. Yes.

In addition, in the technology described in Patent Document 2, as a group management system for managing a plurality of elevators, the degree of demand is determined based on statistical data, and the threshold corresponding to the rated number of passengers corresponding to the maximum number of passengers in the car is exceeded. It is described that a plurality of cars are assigned to a call.

: JP-A-3-256980 : JP 2011-195280 A

However, in the technique described in Patent Document 1, only the number of waiting passengers at the landing is considered, and the situation of the car that is already waiting in the door open state is not considered. I don't know when to open the waiting car inside, and eventually, there is a problem that I can't open the next waiting car until the door opens to a predetermined load or a predetermined time elapses. . As a result, even when there is a large number of waiting passengers at the time of congestion, the door-closing standby car cannot be opened until the above conditions are satisfied, so that it is difficult to open the door and the waiting time until getting into the car becomes long. In addition, there is a concern that if the car with a large number of waiting passengers is opened, the number of passengers may be insufficient and the number of passengers may not be increased when crowded.

The technique described in Patent Document 2 is based on the idea of allocating a plurality of cars according to the demand level only at a certain point in time, and if the car has already been dispatched after a lapse of time, The demand level alone does not tell whether the number of cars is appropriate, and it is also necessary to consider the situation of cars already dispatched. Demand for elevators is changing at a short time level in minutes, and in addition, considering the riding situation of the elevator car, if you do not carry out control according to the situation, it is possible to dispatch the appropriate number of cars difficult.

In order to achieve the above object, the present invention provides an elevator group management system for controlling the operation of a plurality of cars, a means for detecting the number of users at an elevator landing on a predetermined floor, and a door on the predetermined floor. Based on the means for detecting the number of passengers in the car that is open and stopped, and the number of passengers in the car and the number of passengers in the car based on the number of passengers in the platform and the number of passengers in the car, And a means for calculating, and a means for opening the car when the car is stopped at the predetermined floor when the door is closed.

According to the present invention, the user can be efficiently transported in the car, and the waiting time for the elevator of the entire user can be shortened.

The elevator group management system of Example 1 will be described.

The elevator system transports a large number of users smoothly and safely every day as a means of vertical movement in the building. Particularly in a large building, since there are many users, a plurality of elevators are installed, and the group management system manages these elevators as a group.

One of the most important performance indicators of an elevator system is the transport capacity (calculated by the number of transporters / time required) that represents the number of transporters per given time. At times, measures to improve transportation capacity are important. In order to increase transportation capacity, it is important to transport more people in a shorter time, and the solution is to use an elevator car that is waiting at the elevator platform on a crowded floor such as the lobby floor. Focus on utilization.

Here, first, the control of a standby elevator car in a general elevator group management system will be described. When there are several elevator cars in standby on the elevator platform on one floor, in principle, open only one car (open the car and the landing door) and let the rest of the cars remain closed Operation is being implemented. This is because when a plurality of cars are parked on the same floor with the door open, the car first departs from the car by pushing the door close button in the car, leaving the car one after another. In order to avoid this, the operation efficiency is reduced.

For this reason, even when there are many users at the elevator platform during a busy hour, in principle, only one unit is operated as a stand-by standby, and it is operated so that it is first placed in the open-open standby car. Here, when there is congestion, basically, many elevator cars are traveling with users on them, and there are few cases where a plurality of standby elevators are generated, and there is usually no problem in such operation.

However, if the number of elevators under group control is large (for example, 8 or more), and if the number of service floors is small and one lap time is short, multiple stand-by elevators may be generated at the platform even in crowded locations. Sex comes out. In particular, the number of cases is considered to increase as the number increases.

In the example of this embodiment, when a user arrives one after another at an elevator landing on a specific floor, such as when going to work or at the latter half of lunch, especially for the management of a large number of elevator groups, When there are multiple standby elevators, the aim is to improve the transportation capacity by effectively using them. In the situation where there are multiple standby elevators at the elevator landings on the predetermined floors such as the lobby floor and the dining hall floor, and users come to the landing one after another during crowded times, the basic idea of effective use of this standby elevator is as follows .

(1) Detect the number of users at the elevator platform, the number of passengers in the elevator car that is already waiting for door opening, and real-time (continuously from time to time) to match these usage conditions (number of users) Determine the elevator car that will be waiting for the door to open (select multiple units according to the situation) and control.

(2) For each elevator car that has been placed on standby in the doors, each user can enter the car smoothly so that each user can get on smoothly without wasting time, and each car will not start with a small number of people. Lead to.

The idea of (1) above is particularly important. If the number of doors to be opened is less than the number of passengers, users will need to wait at the landing unnecessarily. Or leave the car for a long time, and in either case will reduce transport capacity.

Examples of the embodiment based on the idea of utilizing the door-opening standby car in (1) and (2) above will be described below with reference to FIGS.

First, FIG. 1 shows a functional block diagram of the entire system. From the left of the figure, the overall configuration is input information (calling platform, building entrance / inside / number of elevators / cars, time), elevator group management control means 100, elevator control means 200 (for each number of elevators) This means is provided, but in this figure, one is represented as a representative), elevator 300 (this is also provided for each of several elevators, but one is represented in this figure) It comprises information guide means 400 for the car. The elevator group management control means 100 performs overall control of each elevator number control means 200, and the elevator number control means 200 controls each elevator number 300 according to this.

The elevator group management control means 100 includes a landing call assignment control means 110, a car dispatch control means 120 to a predetermined floor, a traffic state detection means 130 in the building, and a door opening standby control means 140 corresponding to the use state in real time. The landing call assignment control means 110 assigns the elevator car to be serviced for the landing call, and the car dispatch control means 120 to the predetermined floor is the elevator car at the time of congestion such as when going to work (the car for which the service to the call has been completed). Will be controlled to dispatch to the crowded floor (lobby floor if working). Each of them is assigned to a plurality of cars, and has a control of dispatching a plurality of cars. The in-building traffic condition detection means 130 detects the traffic condition such as at work or lunch from the time and number information, and car dispatch control is executed based on this detection information.

The door open standby control means 140 corresponding to the use state real time is the main control in this embodiment. This is a real-time response to the number of passengers at the platform and the number of people in the elevator car when multiple cars are stopped (standby) on a specific floor due to landing call assignment and vehicle allocation control. Control the elevator car standing by. Here, a feature is that the number of cars corresponding to the number of users is put on standby. The control input information is information on the number of people in the entrance of the building, the building, the elevator platform, the number of people in the car, and the state information (door open / closed state, stop, etc.) of each car obtained from the elevator control means 200. The information guidance means 400 for the door-opening waiting car provides information on the car waiting for the door-opening to the elevator platform user, and guides the user to smoothly get into the car that is opening the door.

As described above, the door-open standby control means 140 corresponding to the use state real-time is used by the user when a plurality of cars are stopped on a predetermined floor due to landing call assignment or car dispatch control at the time of congestion. It can be used effectively according to the situation (open the door and put the user on it) to increase transportation efficiency. Hereinafter, the details of the door-open standby control means will be described with reference to FIG.

Fig. 2 shows a functional block diagram of the entire system mainly for door opening standby control. Among the entire configuration, the control means 200 of each elevator unit, the elevator main body 300, and the information guide means 400 regarding the door-opening standby car that gives output information from the group management to the user are the same as in FIG. Description is omitted. The other parts correspond to the door open standby control means corresponding to the use state of FIG. 1 in real time. Hereinafter, this part will be described.

2 comprises the door opening standby control real-time determination means 141, the door opening standby car selection means 142, and the door opening standby car control means 143. The real-time judging means 141 for performing the door-opening standby is based on input information such as the number of passengers at the elevator platform and the number of passengers already waiting for door-opening. If so, determine whether to open the door. The point is that the necessary information is calculated and determined internally so that it can respond to the usage situation in real time. When it is determined that the door is to be opened, the door-opening standby car selection unit 142 selects a door-opening standby car from among the cars that are waiting for the door to close. The door-open standby car control means 143 outputs a command to the elevator car control means 200 of the car so as to open the selected car (waiting for door closing). As a result, the car opens the door and enters a door open standby state, and a user at the landing can get in.

Of the above-described configuration of the door-opening standby car control, what is important is the real-time determining means 141 for performing the door-opening standby, and details thereof will be described below. The real-time determination means 141 for performing the door-opening standby is a means for calculating the number of people who can board the open-door standby car 1411; a means for calculating the number of users who cannot enter the door-open standby car 1412; Consists of 1413.

First, the possible number of passengers calculating means 1411 for the already opened car is the number of passengers in the already waiting car detected by the already opened car detecting means 502, Using the number of cars already waiting to be opened detected by the number detection means 201 and the maximum number of passengers set by the maximum number of passengers setting means 150, boarding into a car already waiting for opening The possible number of people (total number of people in the case of multiple units) is calculated by the following formula.

Equation (1) subtracts the number of passengers in the car from the maximum number of passengers in the car for each open car, and calculates the number of people that can enter the car. The total number of people that can be boarded in the entire open-door waiting cage is calculated. Here, the number of passengers detecting means 502 in the already opened car is a load sensor in the car and an in-car image sensor (camera etc.). Further, the number detection means 201 of the already opened waiting car detects from the data in the elevator control means 200 (actually, the data in the elevator control means is used as it is rather than detection). The maximum number of passengers setting means 150 sets a substantial maximum value of the number of passengers in the car. This value is between 60% and 80% of the rated passenger capacity of the car, and is set to a value that matches the building situation (automatic setting by machine learning, setting by the operator, etc.). This car boarding maximum number of people setting means 150 functions as the elevator group management control means 100 (FIG. 1).

Next, the means for calculating the number of users 1412 who cannot enter the waiting car for open doors is the number of people who can enter the waiting car for open doors calculated by the means for calculating the number of passengers waiting for opening door 1411, the elevator platform, Using the elevator hall detected by the nearby user number detection means 501 and the number of users in the vicinity, the number of users who cannot enter the car that is already waiting for opening is calculated. In another expression, this means the same as the number of users who have overflowed from the open car in the open door, and in another expression, the number of users left in the open car. The calculation formula is as follows.

Number of users who cannot board = Number of people in the platform and nearby-Number of people who can board-Formula (2)
Here, the elevator platform and the number of users detecting means 501 in the vicinity thereof include an image sensor, a laser sensor, an ID (personal identification) tag carried by the user, etc. installed in and near the elevator platform on the target floor. It becomes a sensor to detect.

The door opening execution judgment means 1413 of the door closing standby car is the number of users who cannot enter the door opening waiting basket calculated by the number of users calculating means 1412 and the door closing waiting car detection means. If there is a car that is waiting for door closing at that time, based on the information on the presence / absence of the car and the number of cars that are detected in 202 and the maximum number of passengers in the car using the maximum number of passengers setting means 150, the information is displayed. It is determined whether or not to make it. This determination is performed according to the following equations (3) and (4).

Number of users who cannot get into the car waiting for opening the door ≧ Maximum number of passengers in the car ・・ Formula (3)
And the number of cars waiting to close on the floor> 0 ・・ Expression (4)
Here, the door closing standby car detection means 202 detects from the data in the elevator number control means 200 (same as the number of door opening standby car detection means 201).

The meaning of the formulas (3) and (4) is that the number of passengers at the landing that cannot enter the car that is already waiting to be opened is greater than or equal to the maximum number of passengers in the car, and the target floor is closed. This means that when there is an inside car, the door-opening of the door-closing standby car is carried out. Here, the reason why the number of passengers that cannot be boarded is greater than or equal to the maximum number of passengers in the car is to increase the boarding ratio of the car (the ratio of the actual number of passengers to the maximum number of passengers). For example, there is a small number of people who can not get in, and if a new door is opened, the car will leave with a small number of people, and there is a risk that users who come to the platform later will wait a long time. There is. Therefore, it is not necessary to open the door until the number of passengers reaches the maximum number of passengers, but by opening the door when it reaches, everyone gets in in a short time, so the boarding rate increases and the time required for boarding is short It is possible to improve transportation efficiency.

That is, in an elevator group management system that controls a plurality of cars, a detection unit (intra-building traffic condition detection means 130) that detects the number of users at an elevator landing on a predetermined floor, and a door on the predetermined floor. Based on the number of people in the car that has stopped, the number of people calculation section (capable number of people calculation means 1411), the number of passengers in the platform and the number of passengers in the car, stop at the predetermined floor A car number calculation unit (station call assignment control means 110) that calculates the number of cars and a car control unit that opens the car when there is a car that is closed and closed on a predetermined floor. (Door open standby control means 140).

The number calculation unit calculates the number of people who can enter the car from the number of passengers in the car with the door open, and the car control unit calculates the number of passengers at the detected platform and the calculated boarding number. Based on the possible number of people, if there is a car that is closed and closed on a given floor, the car is opened.

In addition, if the number of passengers at the boarding area is larger than the number of passengers that can be boarded, the car control unit opens the car that is closed and closed on the predetermined floor.

Further, a storage unit (maximum number of passengers setting means 150) for setting the maximum number of passengers in the car is provided in advance, and the car control unit determines whether the difference between the number of passengers at the boarding area and the number of people who can board the car is If the number of passengers is greater than the maximum number of passengers, the car that is stopped at the predetermined floor is opened.

In addition, the number of people who can not enter the car that has been opened and stopped among the users of the platform based on the number of users at the boarding area and the number of passengers in the car that has been opened. The car control unit opens the car when there is a car that is closed and closed on the predetermined floor, based on the calculated number of passengers that cannot enter the car.

In addition, when it is determined that there is a person who cannot get into the car, the car control unit opens the car that is closed and closed on the predetermined floor.

In addition, when it is determined that the number of passengers that cannot enter the car is greater than the maximum number of passengers in the car, the car control unit opens the car that is closed and closed on the predetermined floor.

In addition, when the car control unit (door opening standby car selecting means 142) selects a car to be newly opened and closed from a car that has been closed, there is already a car that has been opened and stopped. Choose the car that is farther from the elevator entrance than the car.

Also provided is a display unit (information guide means 400) for displaying position information at the platform of the opened car.

In addition, there is a stop time calculation unit that determines the stop time for a car that has been door-open stopped, and the car control unit will check whether the elevator that has stopped doors expires or the number of passengers in the car Alternatively, when either the load value reaches a predetermined value or more is satisfied, the car is closed and started.

In addition, the stop time calculation unit calculates the remaining time from the set stop time and the elapsed time of the elevator while the door is stopped to the end of standby, and the number of people calculation unit calculates the door opening from the detected number of passengers in the car or the load value. The display unit displays the position information on the platform of the car that has been opened and stopped, the calculated remaining time, and the number of people that can be boarded. The above is the control processing content of the real-time determination means 141 for performing the door-opening standby, which is the key of the present embodiment. Hereinafter, the concept of the control process will be described again with reference to FIG.

FIG. 3 is a diagram for explaining the concept of the control process for real-time determination of the door opening standby execution. First, there are the number of users (Y01) at the elevator platform on the target floor and the number of users heading to the platform. The user heading to the landing corresponds to the user at the landing at a few minutes ahead. There is a car (Y02) that is already waiting for door opening and the number of passengers (Y03) that are already in the car. Further, the number of passengers that can be boarded in the door-opening standby state (Y04) is obtained by subtracting the number of passengers already on board (Y03) from the maximum number of passengers in each car. The users at the boarding area will board the places where they can board. Then, when the number of passengers reaches the maximum number of passengers or when a predetermined time has passed, the passenger car departs (the number of passengers in that car departs). The above is a series of continuous processes in which the user enters the elevator landing, gets into the car from the landing, and the car departs.

Based on this process, the number of users at the landing (Y01) and the number of passengers that can enter the car waiting for door opening (Y04) are detected in real time. And the condition (3)), the sequential determination to further increase the number of door-opening standby cars is a feature of the control for determining the door-opening standby car in real time in this embodiment. Based on this idea, the start timing and the number of doors that are open to the door are appropriately controlled according to the number of users at the landing (Y01) and the number of passengers that can enter the car that is waiting for doors to open (Y04). As a result, users who come to the elevator landing one after another can prepare and board the door-open standby car appropriately, and can improve transportation efficiency by suppressing useless time delay and improving the boarding rate.

Hereinafter, returning to FIG. 2, the contents of the functional blocks of the entire system mainly for door-open standby control will be described.

The door-opening standby car control means 143 manages the door-opening standby car in addition to the door-opening of the door-closing standby car. Specifically, it manages the number of passengers in the car and the elapsed waiting time of each door open waiting car, and when the number of passengers in the car reaches the maximum number of passengers in the car (set by the maximum number of passengers setting means 150), Alternatively, when the door open standby time (set by the door open standby time setting means 160) is reached, it is determined that the door open standby has been completed, and the car is closed to leave. Here, the door opening waiting time setting means 160 is a control means in the elevator group management control means 100 in the same way as the car occupant maximum number of people setting means 150. The door open waiting time is set in the range of 10 to 20 seconds and is set by the operator.

The information guidance means 400 regarding the door-opening waiting car guides and provides information regarding the door-opening waiting car to the user of the landing so that the user of the landing can smoothly enter the door-opening waiting car. The information to be provided includes information on the position (layout) of each open door in the platform, the number of people that can enter the open door, the order of departure of each open door and the remaining time until departure, and destination floor information for each car (express operation) If the destination floor is assigned to each car in advance as in the case of time). The input to the information guide means 400 is obtained from the machine name information (used for position information) of the door-opening standby car obtained from the door-opening standby car control means 143, and the number of persons capable of boarding the door-opening standby car calculating means 1411. There are the number of passengers that can enter the waiting car for each door opening, and the remaining time until the departure of each car obtained from the door opening waiting car departure time calculating means 145.

In the door-opening waiting car departure remaining time calculating means 145, the difference between the door-opening waiting time set by the door-opening waiting time setting means 160 and the waiting elapsed time calculated by the door-opening waiting-car waiting time calculating means 144 is calculated. The remaining time until departure is calculated. Further, the waiting time calculation means 144 of the door-opening standby car measures the elapsed time from the door opening start of each door-opening standby car, and is shown here for the sake of clarity. The elapsed time is counted by the standby car control means 143, and it may be used as it is.

Finally, the additional assignment determination unit 111 in FIG. 2 will be described. This additional allocation judgment means, when there is a user who can not get into the open waiting car (the number of people is greater than zero), and there is no door closing waiting car on that floor, additional allocation of a new car on that floor Determine. This determination result is output to the assigned car selection means (the process in reference numeral 110 in FIG. 1), and in the case of performing additional assignment, an appropriate assigned car is selected there.

This additional allocation judgment means assumes that there are a large number of elevator users from a specific floor at the end of a large meeting or event, for example. If the number of people calculation means 1412 determines that there is a user who can not get in, and there is no door-closing waiting car on the floor, the purpose is to assign a car to carry the user in advance and dispatch the car It is said. By allocating in advance, the allocated car is dispatched to the target floor, and it is possible to quickly enter the user by waiting for door closing or opening the car.

FIG. 4 shows an operation flowchart corresponding to a functional block diagram of the entire system mainly using the door open standby control shown in FIG. The contents of this flowchart will be described below.
First, it is determined whether or not the target floor is a floor on which a plurality of door-opening standbys are performed (processing F01). Normally, only one unit is set to open door standby. However, when the open door standby control is performed in real time corresponding to the use state shown in FIG. 1 and FIG. 2, multiple open door standbys occur. Judge as follows. Therefore, it is the same meaning that the door open standby is performed in real time corresponding to the multiple door open standby and the use state. In addition, such floors are floors on which a large number of people use elevators, such as lobby floors, cafeteria floors, and floors with large conference rooms.

If the answer is Yes at the floor where the multiple door open standby is performed, it is next determined whether or not it is time (or traffic flow state) to execute the multiple door open standby (processing F02). For example, when working, late lunch, or the end of a large meeting corresponds to the time for waiting for the door to open.

If the time for multiple stand open standby is Yes, then the following data for the target floor is detected or calculated from the sensor or past data (Process F03): number of users near the elevator platform and the platform, The number of passengers in the open waiting basket, the number of open waiting cars, and the number of closed doors. Here, the vicinity of the elevator platform refers to the area from the entrance of the platform, the entrance of the building to the elevator platform.

After detecting or calculating the above data, the number of people that can enter the waiting car is calculated from the following formula (processing F04).

(Number of cars in the open stand-by waiting car x maximum number of passengers in the car)-Total number of people in the open stand-by waiting car formula (5)
Or

Here, equation (5) and equation (6) are the same, and both calculate the number of people that can enter the waiting car with the door open. Moreover, Formula (6) is the same formula as Formula (1).

After calculating the number of people who can get into the waiting car with the door opened as described above, the number of users who can not get into the car with the door opened is calculated by the formula (2) already described (processing F05). Here, when the value of the expression (2) is negative, the value is set to zero.

Using the calculated number of users who cannot enter the open door, the above-described equation (3) is determined, and it is determined whether the number is large enough to satisfy a predetermined condition (processing F06). If the expression (3) is Yes, the determination of the expression (4) already described is further performed to determine the presence or absence of a door-closing waiting car (processing F07).

Finally, if the expression (4) is Yes, it is determined that the door is opened for the door-opening waiting car, a new car that is waiting for the door-opening is selected, and the car is made to wait in the door-opening state (processing F08). ).

The above is the flow of the operation for the functional block diagram of the entire system mainly for the door-opening standby control shown in FIG. 2, so that the number of passengers in the platform and the number of passengers in the waiting car already open In response, a new open door waiting car can be determined sequentially. Accordingly, there is a possibility that not only one but also two, three, and a plurality of door-opening standby may be performed depending on the usage situation. In other words, the number of door-opening waiting cars and the door-opening timing can be controlled in real time according to the usage situation, and the transportation efficiency at the time of congestion can be increased.

Hereinafter, an example of the control operation of the door-open standby that responds in real time to the use state described with reference to FIGS. 2, 3, and 4 will be described with reference to FIGS. 5 to 8 show the status of the elevator platform and the users in the vicinity of the elevator floor on the floor to be controlled for opening the doors (lobby floor) and the number of passengers in each car, respectively. The state in which the door-opening standby control is executed in real time according to the number of people and the number of passengers in the car waiting for the door-opening is described. Hereafter, the operation | movement is demonstrated about each figure.

Fig. 5 (a), Fig. 5 (b), Fig. 6 (a) and Fig. 6 (b) show the landings on the controlled floor of the group-managed elevator system of 6 group-managed elevators and 6 elevators. It represents the situation of the user in the car, and represents the situation according to the passage of time and the operation of the door opening control in this order. The layout of the landing and elevator car is common in each figure, and the same components are denoted by the same reference numerals.

First, FIG. 5 (a) will be described. FIG. 5 (a) illustrates the elevator platform on the floor subject to door opening control (for example, lobby floor) of the six group management elevator systems and the situation in the vicinity thereof. It represents the platform A01, the platform vicinity A02 including the platform entrance, each elevator car or hoistway (Unit 1 A02, Unit 2 A03, Unit 4 A04, Unit 5 A05).

Unit 1 A02 is in a state where the car is waiting for the door to close, the car is waiting on a white background, and the door A021 is closed (the landing and the car door are closed) Is shown. Unit 2 A03 is shown in black, with no car on that floor and traveling on another floor. Units 3 and 6 are in the same state as Unit 2 (the car is traveling on another floor). Unit 4 A04 is in the door open standby state (the car is shown in white), and the door (the landing door and the car door) A041 is open, and the user of the landing is in this car. A circle with the symbol A061 represents one user who has entered the car, and there are 6 passengers in the car. As with Unit 1 A02, Unit 5 A05 has a car waiting for the door closed, and the car is waiting on this floor, but door A051 is closed. There are a total of 16 users in the elevator landing A01 and the entrance vicinity A02. For example, a circle with the symbol A062 represents one of the users in the elevator platform, and a circle with the symbol A063 represents one of the users at the entrance of the elevator platform.

FIG. 5A shows the situation as described above. Hereinafter, the processing state of the real-time determination means (reference numeral 141 in FIG. 2) for performing the door-open standby in the functional block shown in FIG. explain. Although explanation is omitted, the flow of processing is the same as the flowchart of FIG.

First, each detected value and set value are as follows.

(a) Number of users in the elevator platform and the vicinity: 16 people (the elevator platform in FIG. 2 and the number of users in the vicinity thereof 501)
(b) Total number of passengers already waiting on doors open: 6 (number of passengers detection means 502 in the doors waiting to be opened in Fig. 2), where the only car that is waiting for doors open is A04 .

(c) Number of cars already waiting to be opened: 1 (Number of means for detecting the number of cars waiting to be opened in FIG. 2 201)
(d) Cars waiting for door closing: Units A02 and A05 (door closing waiting car detection means 202 in FIG. 2)
(e) Maximum number of passengers in the car: Set to 10 (maximum number of passengers setting means 150 in Fig. 2). Here, the maximum number of passengers in the car is 14 people and the boarding rate is 70%. Set to person.

より Each calculated value and judgment process is as follows based on these detected values or set values.

(f) Number of people who can enter the car that is already waiting for opening the door: From Equation (1), 10-6 = 4 people (Number of people who can enter the waiting car that is already open shown in Fig. 2 1411)
(g) Number of users who cannot enter the car that is already waiting for opening the door: From Equation (2), 16-4 = 12 people (number of users 1412 who can not get into the open waiting car shown in Fig. 2)
(h) Door open / closed judgment of door-open waiting car: Regarding formula (3), the number of users who cannot get into the car waiting for door-opening is 12> the maximum number of people on the car is 10. Regarding equation (4), the number of doors waiting for door closing is 2> 0. From the above, in order to satisfy the condition of the expression (3), the door opening execution of the door closing standby car is determined (door opening execution determining means 1413 of the door closing standby car in FIG. 2).

As described above, in the situation shown in Fig. 5 (a), the number of passengers who cannot enter the car that is waiting for opening doors exceeds the maximum number of people in the car. Determined. As a result, the door-opening standby car selection means 142 in FIG. 2 compares the door-closing standby car No. 1 A02 with the machine No. 5 A05. The control command of the door opening standby is transmitted to the control means 143 and the elevator machine control means 200, and the door opening standby of the No. 5 machine is executed.

Fig. 5 (b) shows the situation after a while since the situation shown in Fig. 5 (a) was waited for the door 5 to open. The same components as those in FIG. 5A are denoted by the same reference numerals, and the description thereof is omitted. As a change from Fig. 5 (a), Unit 5 A05 is in the door open standby (door A051 is in the door open state), the user of the landing boarded in Unit 5, and two people are on board (reference A064). One of the passengers). The number of passengers in Unit 4 A04, which is already waiting for door opening, has increased from 6 to 8. The number of users in and near the platform has changed to 14 in total because of people who have entered the car (subtraction) and those who have newly arrived at the platform (addition).

In this situation, as in the case of FIG. 5 (a), the processing state of the real-time determination means (reference numeral 141 in FIG. 2) for performing the door-opening standby in the functional block shown in FIG. 2 will be described below.

First, each detected value and set value are as follows.

Based on these detected values or set values, the calculated values and determination processing are as follows.

(f) Number of passengers that can enter the car that is already waiting for door opening: From Equation (1), 20-10 = 10 people (g) Number of passengers who cannot enter the car that is already waiting for door opening: Expression (2) 14-10 = 4 people (h) Door open / closed judgment of door-open waiting car: For formula (3), the number of users who cannot get into the car waiting for door-opening is 4 <the maximum number of people in the car is 10. From this, it is determined that the condition of the expression (3) is not satisfied and the door-closing standby car is not opened.

Fig. 6 (a) shows the situation after a further time has elapsed from the situation of Fig. 5 (b). The same components as those in FIG. 5B are denoted by the same reference numerals, and description thereof is omitted. As a change from Fig. 5 (b), the number of passengers in the No. 4 passenger car A04 has reached the maximum number of passengers of 10, and the door open standby car control means 143 in Fig. 2 determines whether the door open standby has ended. Is made. As a result, Unit 4 closes door A041 and the car starts. Unit 5A is in the door open standby state, and the number of passengers in the car has increased to six. There are a total of 10 users at and near the platform.

In this situation, as in the case of FIG. 5 (b), the state of processing of the real-time determination means (reference numeral 141 in FIG. 2) for performing the door-opening standby in the functional block shown in FIG. 2 will be described below.

First, each detected value and set value are as follows.

(a) Number of users in the elevator platform and the vicinity: 10 people (the elevator platform in FIG. 2 and the number of users in the vicinity thereof 501)
(b) Total number of passengers already waiting on doors open: 6 (number of passengers detection means 502 in the doors waiting to be opened in FIG. 2), where the only cars waiting for doors open are A05 . Unit 4 A04, which had been waiting for door opening until now, is now closing and preparing for departure.

(c) Number of cars already waiting to be opened: 1 (Number of means for detecting the number of cars waiting to be opened in FIG. 2 201)
(d) Car in standby state: Unit 1 A02 (door-closing standby car detection means 202 in FIG. 2)
(e) Maximum number of passengers in the car: 10 (Maximum number of passengers setting means 150 in Fig. 2)
Based on these detected values or set values, the calculated values and determination processing are as follows.

(f) Number of people who can enter the car that is already waiting for opening the door: From Equation (1), 10-6 = 4 people (Number of people who can enter the waiting car that is already open shown in Fig. 2 1411)
(g) Number of users who cannot enter the car that is already waiting for opening the door: From Equation (2), 10-4 = 6 people (number of users 1412 who can not get into the open waiting car as shown in Fig. 2)
(h) Door open / closed determination of door-open waiting car: For equation (3), the number of users who cannot get into the car waiting for door opening is 6> the maximum number of people in the car is 10. From this, it is determined that the condition of the expression (3) is not satisfied and the door-closing standby car is not opened (door opening execution determining means 1413 of the door-closing standby car in FIG. 2).

Fig. 6 (b) shows the situation after a further time has elapsed from the situation of Fig. 6 (a). The same components as those in FIG. 6A are denoted by the same reference numerals, and the description thereof is omitted. As a change from Fig. 6 (a), the first car A04 departs from this floor and is traveling on the other floor, and the fifth car A05 has 9 passengers. . Furthermore, as will be described later, as the number of passengers at the platform increases, it is judged that the number of cars waiting for door opening will be newly increased, and the car A02 waiting for door closing will start door opening (A021). . There are a total of 11 users in and around the platform.

In this situation, as in the case of FIG. 6 (a), the processing state of the real-time determination means (reference numeral 141 in FIG. 2) for performing the door-opening standby in the functional block shown in FIG. 2 will be described below.

First, each detected value and set value are as follows.

(a) Number of passengers in and around the elevator platform: 11 (b) Total number of passengers already waiting for opening doors: 9 people, where only No. 5 A05 is waiting for door opening.

(c) Number of cars already waiting for door opening: 1 (d) Cars waiting for door closing: Unit 1 A02. In FIG. 6 (b), the door has already begun to open, but here Think in the situation.

(e) Maximum number of passengers in the car: 10
Based on these detected values or set values, the calculated values and determination processing are as follows.

(f) Number of passengers that can enter the car that is already waiting for door opening: From Formula (1), 10-9 = 1 person (g) Number of users who cannot enter the car that is already waiting for door opening: Expression (2) Therefore, 11-1 = 10 people (h) Door open / closed judgment of door-open waiting car: Regarding formula (3), the number of users who can not get into the car waiting for door-opening is 10 or more, and the maximum number of people in the car is 10 people. For equation (4), the number of cars in the door-open standby> 0. Based on the above, in order to satisfy the condition of Equation (3), it is determined that the door-opening of the door-closing standby car is performed.

As a result of the above determination, the first door A02 of the door-closing standby car has been opened, and the opening of the first door A021 has started as shown in FIG. 6 (b).

As described above, according to the flow of Fig. 5 (a) (b) and Fig. 6 (a) (b), the car in the door open stand-by according to the situation of the elevator user and the number of passengers in the door open stand-by car in real time. The operation of controlling the above has been described. With the control described here, it is appropriate to consider the dynamic situation of users who come to the elevator platform one after another during busy hours such as work and lunch, and people who enter the elevator car waiting for opening from the platform. Because the number of cars and the timing of opening the door can be controlled by the number and timing, users can smoothly get into the elevator car from the platform even when it is congested, the wasted time is suppressed, and the number of passengers can be controlled appropriately. The transportation efficiency of the system can be improved.

7 and 8 show the operation of the door-open standby control by the functional block shown in FIG. 2, similarly to FIGS. FIGS. 7 and 8 differ from FIGS. 5 and 6 in that there is an entrance / exit gate (reference A07 in FIGS. 7A and 7B, reference A08 in FIG. 8) just before the entrance of the elevator platform. In this respect, for example, the lobby floor (entrance floor) is assumed. The point is to detect in advance the person entering the elevator platform at this entrance / exit gate. The contents of the operation will be described below with reference to FIGS.

Figures 7 (a) and 7 (b) show the situation of the users on the floors controlled by the group-managed elevator system of 6 elevators that are group-managed as in Figure 5 (a) and the users in the 6 elevator cars. It represents the situation according to the passage of time and the operation of the door opening control in this order. The layout of the landing and elevator car is the same as in FIG. 5 (a), and the same components are denoted by the same reference numerals. The difference from FIG. 5 (a) is that there is an entrance / exit gate A07, where the number of users heading to the elevator landing A01 is detected in advance. As will be described later, this entrance / exit gate A07 corresponds to the elevator hall and the user number detection means 501 in the vicinity thereof in FIG. The entrance / exit gate A07 may be a security gate or an entrance / exit door.

In the following, description will be given first with reference to FIG. Here, the same components as those in FIG. 5A are denoted by the same reference numerals, and description thereof is omitted. The situation in this figure is that Unit 4 A04 and Unit 5 A05 are waiting for door opening, 9 people are on board, and 5 people are on board. There is only one door closed car, Unit A02, and Units 2, 3, and 6 are not on this floor and are traveling on other floors. There are a total of nine users at the elevator landing A01, and there are two users who are going to enter the elevator landing through the entrance / exit gate A07.

[The point here is that the number of users at the elevator platform is calculated by integrating the number of people entering the elevator platform from this entrance / exit gate. The number of users at the elevator platform is calculated by adding the number of users entering the elevator platform from the entrance / exit gate to the number of users at the elevator platform just before that point, and then entering the elevator waiting for door opening. Subtract. If it does in this way, the number of passengers of an elevator boarding can be detected by calculation by the number detection by the entrance / exit gate and the number detection means in the elevator car. For this reason, the entrance / exit gate A07 in FIG. 7A corresponds to the elevator landing in FIG. 2 and the user number detection means 501 in the vicinity thereof.

Based on this method, the processing of the real-time determination means (reference numeral 141 in FIG. 2) for performing the door-opening standby in the functional block shown in FIG. 2 can be executed thereafter as in the case of FIG. 5 (a). This will be described below.

First, each detected value and set value are as follows.

(a) Number of passengers in and around the elevator platform: 9 (detected by the method described above)
(b) Total number of passengers already waiting for door opening: 9 + 3 = 12 people (passenger waiting number detection means 502 in FIG. 2), where the car waiting for door opening is No. 4 It becomes A04 and Unit 5 A05.

(c) Number of cars already waiting for door opening: 2 (number of means 201 for detecting the number of cars waiting to be opened in FIG. 2)
(d) Car in standby state: Unit 1 A02 (door-closing standby car detection means 202 in FIG. 2).

(e) Maximum number of passengers in the car: 10 (Maximum number of passengers setting means 150 in Fig. 2)
Based on these calculated values, detected values, and set values, the respective calculated values and determination processing are as follows.

(f) Number of people who can board the car that is already waiting for opening the door: From Equation (1), 20-12 = 8 people (Number of people who can board the car waiting for the open door shown in Fig. 2 1411)
(g) Number of users who cannot enter the car that is already waiting for opening the door: From formula (2), 9-8 = 1 (number of users 1412 who can not get into the open waiting car shown in Fig. 2)
(h) Door open / closed determination of door-open waiting car: For equation (3), the number of users who cannot get into the car waiting for door-opening is 1> the maximum number of people in the car is 10. From this, it is determined that the condition of the expression (3) is not satisfied and the door-closing standby car is not opened (door opening execution determining means 1413 of the door-closing standby car in FIG. 2).

Fig. 7 (b) shows the situation after a further time has elapsed from the situation of Fig. 7 (a). The same components as those in FIG. 7A are denoted by the same reference numerals, and description thereof is omitted. As a change from Fig. 7 (a), the number of passengers in the No. 4 car A04 has reached the maximum number of passengers of 10 people, and the door open standby car control means 143 in Fig. 2 determines the end of the door open standby. Is made. As a result, Unit 4 closes door A041 and the car starts. Unit 5A is in the door open standby state, and the number of passengers in the car has increased to five. There are a total of 8 users at and near the platform.

The number of users at and near the platform can be calculated from the situation shown in Fig. 7 (a) using the calculation method described above. From the situation shown in Fig. 7 (a), the number of users at the platform is 2 people (additional) and from Fig. 7 (a). It can be calculated as 9 + 2−3 = 8 from the number of people (subtracted) who entered the door-opening waiting car No. 4 and No. 5 during the time passage of Fig. 7 (b).

Hereinafter, the detection and calculation processing for each person is the same as the above-described processing, and therefore will be omitted.

Fig. 8 shows the structure of the building where the entrance / exit gate A08 is at the entrance of the building and the distance (A08) to the elevator landing A01 is long compared to Fig. 7 (a). For this reason, the person (A066) who entered from the entrance / exit gate A08 is not only the person (A067) going to the elevator landing A01 but also the person (A068) who moves in another direction. In the case of FIG. 8, as in the case of FIG. 7 (a), from the number of people entering the building from the entrance / exit gate A08, the number of people heading to the elevator platform, the number of people entering the car waiting for door opening, It is possible to estimate the number of users at the elevator platform. Specifically, if the number of people entering the building can be calculated from the number of people entering the building from the entrance / exit gate, the number of people going to the elevator platform will be used, and the elevator platform will be used in the same way as in Fig. 7 (a). The number of users in can be calculated. Here, the method of calculating the number of people entering the building from the entrance / exit gate to the elevator platform is a method of statistical estimation from past data (including machine learning), a method of directly detecting by providing sensors Can be considered. Accordingly, the entrance / exit gate A08 in FIG. 8 may be considered to correspond to the elevator landing and the user number detection means 501 in the vicinity thereof in FIG.

If the number of passengers at the boarding point can be calculated, the number of people who can enter the open-door waiting car and the number of users who cannot enter the open-side open car, as described in Figs. 5 (a) and 7 (a) Can be calculated to determine whether or not to open the door with the door closed.

FIG. 9 is a process for selecting a door opening standby car in the control flowchart of the number of door opening waiting cars shown in FIG. 4 (a new door opening standby is performed from the car waiting for door closing on the target floor in FIG. 4). The flowchart which showed the process (F08) which selects the cage | basket | car is represented. In FIG. 9, processes different from those in FIG. Hereinafter, processing portions different from those in FIG. 4 will be described.

If there is a car waiting on the floor with the door closed (if YES as a result of processing F07), the car from the entrance of the platform is more than the car waiting on the door open among the cars waiting for the door closed. It is determined whether there is a car with a long distance (F081). If there is such a door-closing waiting car, the car is set as the next door-opening waiting car (F082). Here, when there are a plurality of such door-closing waiting cars, a car closer to the landing entrance is set.

If there is no door open waiting car that satisfies the condition that the distance from the landing entrance is longer than any car that is already waiting for door opening, the distance from the landing entrance is the most among the cars waiting for door closing. The long car is set as the next door-open waiting car (F083).

According to the method of selecting the door-opening waiting car shown in FIG. 9 above, the user who has come to the landing is closer in distance to the car that is already waiting for door-opening than the car that has been waiting for door-opening. It ’s easier to get in there. In this way, by making it easier to get into the car that is already waiting for the door open, the boarding rate of the car waiting for the door open can be increased, and the overall transportation capacity can be increased. Conversely, if such a selection method is not implemented, the user will first get into the car that has been waiting for door opening, and the car that is already waiting for door opening will leave with a low occupancy rate. This may lead to a decrease in transport capacity.

FIG. 10 shows a flowchart for generating guidance information for the door-opening waiting car (means 400 in FIG. 2) in the embodiment shown in FIG. This is guide information for a user who has arrived at the landing to smoothly get into a plurality of door-open waiting cars.

First, the door-opening standby car control means 143 (FIG. 2) determines whether there is a car that is currently in the door-open standby on the floor where the door-open standby with a plurality of vehicles is performed (F09). If yes, go to the next process, if no, get out of this process.

When there is a car waiting in the door open state, the door opening standby car number-capable number calculation means 1411 (FIG. 2) calculates the number of persons that can enter the car for each door open stand-by car (F10).
This value can be calculated by obtaining the difference in the number of passengers in the car from the maximum number of people in the car.

Subsequently, for each door-opening waiting car, the door-opening waiting car departure remaining time calculating means 145 (FIG. 2) calculates the remaining time until the door-opening waiting time expires (F11). This value can be calculated by the difference between the set value of the door open standby time and the elapsed time from the start of the door open standby of the car.

Further, the door opening waiting car departure remaining time calculating means 145 (FIG. 2) determines the departure order of the car waiting for door opening waiting from the calculated remaining time until the door opening waiting expiration (F12). As the remaining time is smaller, the departure order can be determined first.

Subsequently, the door-open waiting car control means 143 (FIG. 2) determines whether or not a destination floor has been designated in advance for each car waiting for door opening (F13). This is the case for control such as divisional express at work.

If the destination floor is designated in advance, the information guide means 400 (FIG. 2) provides the following information about each car waiting for door opening to the user at the landing (F14).

1) Departure order of the car, 2) Remaining time until expiration of the car's door opening (departure), 3) Number of people who can board the car, 4) Destination floor of the car.

If the destination floor is not designated in advance, information excluding the destination floor information from the information item of F14 is provided (F15).

That is, an order determination unit (car control means 143) is provided for determining the order in which the door-opening stop is finished and the elevator is started from the calculated remaining stop time of the car that has been door-opened. Display the order.

FIG. 11 is a diagram showing an example of information guidance regarding the door-opening waiting car in the embodiment shown in FIGS. 2 and 10. Here, a device such as a large information display device is assumed. In the display display portion B01, information on the elevator car waiting for door opening is displayed together with the simulated image B02 of the elevator platform. The images representing the cars on the boarding area (three cars facing each other in a total of 6 cars) are B03-B08, and correspond to the images of each car of B03, B06, B07 with the message “Can be boarded” Elevator No. (No.1, No.4, No.5) represents the units that can be boarded while waiting for door opening. The user of the boarding area can quickly check the position of the car in the door opening waiting area by looking at this display. The black-painted cars (No.2, No.3, No.6) represent the door-closed state (cars that are not subject to boarding, such as when traveling).

For each car image B03, B06, B07 of each unit that can be boarded while waiting for opening the door, information (B09, B10, B11) that is necessary or helpful for the user to get into the car is presented. ing. Specifically, for each car, information B091 of the remaining time until the car departs and information B092 of the number of people who can get into the car are displayed. Looking at this information, the user can select a machine with a short (short) departure time if he / she is in a hurry, and a person who does not have time to depart. Also, by looking at the number of people that can be boarded, it can be determined whether or not the car can be boarded. In addition, the group management control side aims to encourage boarding by showing information on the number of people on board, because it is possible to improve transportation capacity by placing as many users as possible in the car (increasing the boarding rate). It is said.

As described above, according to the information guidance on the door opening waiting car shown in FIG. 11, the user of the elevator hall quickly knows the position of the car waiting for the door opening, and information on the time until departure and the number of people who can board, Each can choose the elevator car they want. In addition, since there are many users who are in a hurry basically at the time of congestion, it is possible to improve the car occupancy rate and shorten the time required for boarding by using these displays. As a result, the elevator transportation capacity determined by the number of passengers per hour is improved.

FIG. 12 is an example of information guidance regarding the door-opening waiting car in the embodiment shown in FIGS. 2 and 10, and is a diagram showing an example different from FIG. 12, what is different from FIG. 11 shows different reference numerals, and only that portion will be described here. 12 is different from FIG. 11 in that departure order B093 and destination floor information B094 are added to the guidance information for the car waiting for door opening. By adding such information, the user can make a more accurate determination. The destination floor information is indispensable when an operation in which the destination floor is different depending on the unit such as a divided express.

FIG. 13 shows a diagram illustrating an installation example of information guidance related to the door-open standby car in the embodiment shown in FIGS. The information provided here is the content described with reference to FIGS. FIG. 13 shows the situation of the landing (C01) of four group management elevators with two vehicles facing each other. At each landing door (C02, C03, C04, C05) of the four elevators, there are two cars waiting for door opening, and the machines with the symbols C02 and C04 fall under this category. The information display device that provides information should be installed in an easy-to-see position so that users who have arrived at the elevator platform can easily see it, the wall at the entrance of the platform (location of C06 and C07), and the ceiling inside the platform A position hung from (C08) is good.

The elevator group management system of Example 2 will be described. Note that the description of the points in common with the first embodiment will be omitted.

FIG. 14 shows a functional block diagram of the entire system mainly for door opening standby control, and shows an embodiment different from FIG. 14, the same components as those in FIG. 2 are denoted by the same reference numerals, and description thereof is omitted here.

14 differs from FIG. 2 in the internal processing of the real-time determination means 141 for performing the door-opening standby and the number-of-doors-calculating means 146 for entering the door-opening standby car. Here, the number-of-opening-basis-counter calculating means 146 is the same process as the number-of-opening-counter calculating means 1411 for the already-opened waiting car in FIG. Is omitted. Hereinafter, the internal processing of the real-time determination unit 141 for performing the door opening standby will be described.

The internal processing of the real-time determination means 141 for performing the open standby in FIG. 14 includes a door opening waiting car required number calculating means 1414 and a door opening execution determining means 1415 for the door closing standby car.

First, the door opening waiting car required number calculating means 1414 includes the number of persons detected by the passenger number detecting means 501 in the elevator hall and the vicinity thereof, the number of persons detected by the number of passengers detecting means 502 of the already opened door waiting car, and the maximum number of passengers setting means 150. Calculate the required number of door-open waiting cars using the following formula from the set number of persons.

Necessary number of door-opening waiting cars = INT [(number of passengers in the elevator platform and the vicinity of the landing + total number of passengers in the waiting-for-opening car) / maximum number of passengers in the car] formula (7)
In Expression (7), INT represents an integer function processing that rounds off the decimal point of the operation result in parentheses. By calculating the number of standby units required by equation (7), it is possible to determine the number of passengers suitable for the number of passengers and riding conditions. Furthermore, the number of waiting units can be calculated as a necessary and not excessive value by the integer processing.

Next, the door opening execution determination means 1415 of the door closing waiting car determines whether a new door opening waiting car is necessary and whether there is a door closing waiting car by the following two formulas.

Necessary number of open-door waiting baskets> Number of existing open-standby cars ··· Formula (8)
And the number of cars waiting to close doors> 0 ... Formula (9)
When the conditions of these two formulas are satisfied, it is determined that a new door-opening waiting car is necessary, and the door-opening waiting car selection means 142 selects an appropriate car from the door-closing waiting car, and creates a new door. It becomes a waiting basket. The subsequent processing is the same as the functional block diagram of FIG.

The feature of the functional block in FIG. 14 is that the required number is calculated using the number of door-opening waiting cars as an index, and the number of door-opening waiting cars is set accordingly. In particular, in this method, when the number of users increases rapidly, it is possible to open a plurality of units at the same time and wait for the door to open. For example, the required number of open doors in the formula (8) When there are two more cars than the number of cars and there are two or more doors waiting to be closed, it is also possible to control the two cars to open and stand by at a time.

As a result, for example, if there is a large conference room on the floor and the elevator is waiting in advance on that floor, and many users gather at the elevator platform after the conference, multiple It is possible to transport a large number of users in a short time by opening the platform.

In other words, the number-of-cars calculation unit stops the door on the predetermined floor based on the number of passengers at the platform, the number of passengers in the car that has been stopped open, and the maximum number of passengers in the car. The required number of cars is calculated, and the car controller opens the car when there is a car that is closed and closed on the predetermined floor based on the required number of cars.

In addition, if the calculated required number is larger than the number of cars whose doors are stopped at that time, the car control unit opens the cars that are stopped and closed on a predetermined floor.

FIG. 15 shows an operation flowchart for the functional block diagram of the entire system mainly using the door open standby control shown in FIG. 14, and the operation flowchart of FIG. 4 is changed. In the operation flowchart of FIG. 15, the same processes as those in FIG.

In the operation flowchart of FIG. 15, the difference from FIG. 4 is that the required number of door-opening waiting cars is calculated by formula (7) (F16), and the required number of door-opening waiting cars is the number of already-opening waiting cars. There are two points in the process (F17) for determining whether or not it is larger than (8).

The effect of the control according to the operation flowchart of FIG. 15 is the same as that of FIG. 14, and the number of door-open waiting cars required according to the situation of the user is calculated, and compared with the number of cars already waiting for door opening, The number of cars that should be opened and closed at the same time is calculated, and the simultaneous opening and closing control of a plurality of cars is possible according to the usage situation.

As described above, the control of the elevator car in the door open standby that responds in real time to the use state described so far becomes more effective as the number of elevator group management systems becomes larger. Specifically, it is considered effective for group management of 8 or more units, and the reason will be described below.

Generally, one lap time for an elevator is set to about 60 to 120 seconds. If the lap time is 60 seconds, the number of elevators for group management is large, and if there are 8 or more elevators, the average arrival interval of cars to a given floor (eg lobby floor) is 60 seconds / 8 cars = 7.5 Second. The waiting time of the elevator car (standby stop time when the door is opened) is assumed to be 10 to 15 seconds considering the time required for boarding a large number of people, and one car on the lobby floor is waiting for the door to open. Is more likely to arrive on the lobby floor. Therefore, the execution opportunity of the plurality of door opening standbys described so far in the present embodiment increases. As the number increases, the opportunity increases. For example, if the number of cars is 12 and the lap time is 60 seconds, the average arrival interval to the lobby floor is 5 seconds and the waiting time is about 15 seconds. There is a possibility that the number of waiting cars on the floor may increase to three, and if there are a large number of elevator users, if two or three waiting elevator cars are made to wait in the open position, many people will be waiting at the same time. It can be carried in In this way, the concept of controlling by opening and closing a plurality of doors in one embodiment shown in FIG. 1, FIG. 2, FIG. 14 and the like is particularly effective in the management of a large number of elevator groups of 8 or more. The effect is considered to increase as the number increases.
