Description

  The present invention relates to an elevator group management control device that performs group management control of operation of a plurality of elevators, and in particular, an elevator group management control device including a landing destination call registration device that registers a destination floor call at a landing on each floor. About.

  In recent elevators, there is one in which a call for a destination floor can be registered in advance at a landing on each floor. This is called a “destination destination call registration device”, and an operation panel having a destination floor button is installed at the landing on each floor, and the destination floor call is automatically registered at the landing through the operation panel (for example, , See Patent Document 1).

In an elevator equipped with such a landing destination call registration device, the passenger's destination floor can be known in advance, and there is an advantage that the car of each car can be efficiently responded. In this case, when a landing destination call is registered, a method is generally used in which allocation control is performed in consideration of the congestion status of each unit, and an optimal car is responded to the landing.
JP-A-6-92555

  However, the conventional assignment control method for a landing destination call does not take into account a change in the situation after the assigned car (the car that responds to the landing) is determined. For this reason, if another passenger gets on the middle floor, the passenger waiting at the landing may not be able to get in, and so-called “unloading” occurs, which may make the passenger feel uncomfortable. It was.

  More specifically, it is assumed that there is a passenger who is waiting for a destination call registered on the fifth floor. When the first call is assigned to the destination call and stops on the way to the 5th floor to drop the passenger, when another passenger gets in, the first car may be changed depending on the situation in the car. When you get to the 5th floor, it is almost full and you may not be able to board.

  In such a case, the passengers who could not get in the car feel unpleasant, and the registered destination call will be canceled due to the landing of the car, so the passenger needs to re-register. There were problems such as.

  The present invention has been made in view of the above points, and in the event that passengers are left behind, there is no need for re-registration by the passengers and an elevator capable of responding to other platforms in the hall. An object is to provide a group management control device.

  The elevator group management control device according to the present invention is an elevator group management control device that performs group management control of the operation of a plurality of passenger cars, and is installed at a landing on each floor, and an operation panel capable of registering the same destination floor repeatedly. The destination destination call reception means for receiving the destination call information registered by the operation of the operation panel, the destination call information of each floor received by the landing destination call reception means, and the operation information of each car. Based on the assignment control means for determining the car to respond to the hall where the destination call is newly registered and outputting an assignment command to the car, and the car determined by the assignment control means is An unloading judging means for judging whether or not passengers on the same destination floor waiting at the landing are left unloaded, and the allocation control means To add assigned to another car when Tsuminokoshi passenger is determined by the determination means, characterized in that to respond to the landing.

  According to the present invention, when passengers are left unloaded, other passenger cars can be made to respond to the hall without requiring re-registration operations by the passengers.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a diagram showing a configuration of an elevator hall according to the first embodiment of the present invention. Here, an example is shown in which three elevators (cars) from No. 1 to No. 3 are arranged in parallel in the building. The halls on the other floors have the same configuration.

  In the figure, 11 is an elevator hall, and holders 12 corresponding to the elevators are arranged in parallel. When the elevator (car) arrives, the hold door 12 is connected to a car door (not shown) and opens and closes. Next to the hold door 12, an operation panel 13 for passengers to register the destination floor at the hall 11 is arranged.

FIG. 2 shows the configuration of the operation panel 13 for destination call registration.
The destination call registration operation panel 13 is provided with a destination floor button 21, a disabled person button 22, a response car guidance display unit 23, and a response car guidance broadcast unit 24.

  On this operation panel 13, an arbitrary floor can be registered as a destination floor by pressing the destination floor button 21. In this case, it is possible to register the same destination floor repeatedly. For example, it is assumed that the passenger a has registered the 10th floor as the destination floor. At that time, the other passengers b and c can register the 10th floor again through the same operation panel 13 or another operation panel 13 installed at the landing.

  In addition, the operation panel 13 can notify the disabled person by pressing the disabled person button 22 together with the destination floor button 21.

  In addition to the guidance display of the car responding to the hall, the response car guidance display unit 23 displays a guidance display such as when the responding car is changed, when the car passes, or when the direction is reversed. Do. The response car guide broadcasting unit 24 performs these guidance displays by voice.

Next, the configuration of the elevator group management control device will be described.
FIG. 3 is a diagram showing the overall configuration of the elevator group management control apparatus according to the first embodiment of the present invention, in which a configuration in which three elevators (cars) are arranged in parallel is shown. .

  The group management control device 31 includes a computer equipped with a CPU, ROM, RAM, and the like, and performs group management control of a plurality (three in this case) of cars 42a, 42b, and 42c under management. The single control devices 41a, 41b, 41c are provided corresponding to the respective cars 42a, 42b, 42c, and operate the respective cars according to instructions from the group management control device 31. These single control devices 41 a, 41 b and 41 c are also configured by a computer in the same manner as the group management control device 31.

  Further, load detectors 43a, 43b, and 43c for detecting the load in the car are installed in the cars 42a, 42b, and 42c, respectively. The detection signals of these load detection devices 43a, 43b, and 43c are given to the group management control device 31.

  Here, in the present embodiment, the group management control device 31 is provided with a landing destination call reception unit 32, a management table 32a, an allocation control unit 33, an unloading determination unit 34, and a guide unit 35.

  The landing destination call accepting unit 32 collectively receives destination call information transmitted by operating the operation panels 13a, 13b, 13c... Installed at the landings on each floor, and holds the information in the management table 32a for each floor.

  The allocation control unit 33 acquires the destination call information of each floor from the landing destination call reception unit 32 and includes the position and traveling direction of each car (car), the number of passengers, and the like from the single control devices 41a, 41b, 41c. By acquiring the operation information, a car to be responded to the hall in which the destination call is newly registered is determined, and an allocation command is output to the car.

  The unloading determination unit 34 determines whether or not passengers on the same destination floor waiting at the landing are left unloaded when the car determined by the allocation control unit 33 reaches the landing. Specifically, the load values before and after landing are detected by a load detection device installed in the car, and it is determined that there is an unloading when there is no load change. When the unloading determination unit 34 determines that there is unloading, the allocation control unit 33 performs additional allocation to another car.

  The guide unit 35 transmits the guidance information of the car responding by the assignment control unit 33 to the operation panel 13 installed at the landing.

Next, the operation of the embodiment will be described.
The information on the destination call is transmitted from the operation panels 13a, 13b, 13b... Installed at the landings on each floor and received by the group management control device 31. This destination call information includes the hall where the destination call is registered, the destination floor of the passenger at the hall, the number of registrations, the type of passenger (general / handicapped), and the like. The hall destination call receiving unit 32 receives the information on the destination call of each floor, and stores it in the management table 32a as shown in FIG. 4 for each floor.

  FIG. 4 is a diagram showing an example of a destination call registered at the landing on the first floor, and information on the destination floor, the number of times of registration, and the type of passenger is held. The number of registrations is the number of times the destination floor has been registered. This example shows that the second-floor bound is registered twice and the fifth-floor bound is registered once. The passenger type distinguishes whether the passenger is a general person or a handicapped person, and here, it is shown that the passenger who registered for the fifth floor is a handicapped person.

  In addition, although "a disabled person" shows the person who needs a wheelchair fundamentally here, it shall include the passenger who gets on with an object with a certain amount of weight other than a wheelchair, for example.

  Here, when a destination call is newly registered at a landing on a certain floor, processing as shown in FIG. 5 is executed.

  FIG. 5 is a flowchart showing the processing operation of the group management control device 31. Note that the processing shown in this flowchart is executed by the group management control device 31 that is a computer reading a predetermined program.

  First, when a destination call is newly registered at a landing on a certain floor, the allocation control unit 33 provided in the group management control device 31 acquires information on the destination call from the landing destination call reception unit 32 (step S101). ). Then, the allocation control unit 33 determines a car to be responded to the destination call in each of the cars 42a, 42b, and 42c using a predetermined evaluation function and the like, and assigns an instruction to the determined car. Is output (step S102).

  When the car that has received the allocation command has landed on the landing (Yes in step S103), the unloading determination unit 34 determines whether or not a passenger on the same destination floor waiting at the landing has been able to get on the car (step). S104). If the passenger cannot get in the car, it is determined that there is an unloading (Yes in step S104), and that is notified to the assignment control unit 33. As a result, the assignment controller 33 makes an additional assignment to another car and responds to the hall (step S105).

  Here, the determination of the unloading in step S104 is made based on the load change of the car that has landed on the landing.

  More specifically, it is assumed that the destination call for the 8th floor is registered by the passengers a and b at the 5th floor landing in the operation state as shown in FIG. 6, and the first car 42a responds. . Further, it is assumed that passengers A, B, C, and D are already in the car 42a.

  Since the process is complicated, if one platform responds to a destination floor and another destination floor is registered at the same platform, another platform is assigned to each floor platform. It shall respond.

  When the car 42a arrives at the 5th floor hall, passengers a and b can get in if there is sufficient boarding space in the car. In this case, since the load of the car 42a increases more than before landing, it can be determined that there is no unloading from the load change.

  In addition, when the passenger car 42a arrives at the landing on the fifth floor, some of passengers A, B, C, and D may get off there. In this case, if it is a standard car size, the passenger who gets into the car and the passenger who gets off do not act at the same time, and usually the passenger waiting at the landing boardes after the passenger gets off. Therefore, the presence or absence of unloading can be determined by looking at the load change based on the load value after the passenger gets off.

  On the other hand, when the car 42a stops on the way to the 5th floor (assumed to be the 4th floor), if another passenger gets in from the 4th floor, it may be possible to reach the 5th floor in a state that is almost full. In such a case, the passengers a and b cannot get in, so the load does not change before and after landing. Therefore, when there is no load change, it can be determined that “there is no leftover”.

  If it is determined that there is an unloading, the fifth floor call information stored in the management table 32a is held as it is, and the fifth floor is additionally allocated to the car 42b or the car 42c. In the example of FIG. 6, the car 42b is traveling upward from the first floor, and additional allocation is made to this car 42b. In actuality, not only the car position and the traveling direction but also the number of passengers and the destination floor of each passenger are taken into consideration, and an additional allocation is made to the optimum car.

  When a car to be responded to the 5th floor hall is determined, guidance to that effect is given to the hall through the guide section 36. Specifically, a guidance display such as “No. 1 machine responds” is displayed on the response car guidance display section 23 provided on the operation panel 13 shown in FIG. 2, for example, as shown in FIG. At the same time, a similar guidance is output from the response car guidance broadcasting unit 24 by voice.

  Also, if another car responds to the landing due to the additional allocation, for example, as shown in FIG. 7B, “No. 2 will respond, so please wait.” Guidance is made.

  In this way, when the car arrives at the landing, it is determined whether passengers on the same destination floor waiting at the landing are left unloaded, and when left unloaded, other cars are made to respond. As a result, if the passenger who could not get on is waiting on the spot, he / she can go to the target floor by taking the next car without re-registering the destination floor again.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the first embodiment, it is determined whether or not passengers on the same destination floor waiting at the landing are left unloaded, and when left unloaded, other cars are made to respond by additional allocation. However, even if the other car responds, if the boarding space does not satisfy the number of unloading passengers, the unloading may occur again. Therefore, the second embodiment is characterized in that the number of unreserved persons is detected, additional allocation is made to a car that can accommodate the unreserved persons, and the platform is made to respond.

  FIG. 8 is a diagram showing an overall configuration of an elevator group management control apparatus according to the second embodiment of the present invention, in which a configuration in which three elevators (cars) are arranged in parallel is shown. . In FIG. 8, the same components as those in FIG. 3 in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The difference from the configuration of FIG. 3 is that a group number detection unit 36 is added to the group management control device 31. The unloading number detection unit 36 detects the number of unloading when it is determined by the unloading determination unit 34 that “there is unloading”. Specifically, the number of passengers waiting on the same destination floor is detected with reference to the management table 32a, and the number of passengers who could not get on the car by comparing the number of passengers with the load change of the car. Ask.

The processing operation in the second embodiment will be described below.
FIG. 9 is a flowchart showing the processing operation of the group management control device 31. Note that the processing shown in this flowchart is executed by the group management control device 31 that is a computer reading a predetermined program.

  In FIG. 9, the processing from step S201 to S204 is the same as that from step S101 to S104 in FIG. That is, first, when a destination call is newly registered at a landing on a certain floor, the allocation control unit 33 provided in the group management control device 31 acquires information on the destination call from the landing destination call reception unit 32 ( Step S201). Then, the allocation control unit 33 determines a car to be responded to the destination call in each of the cars 42a, 42b, and 42c using a predetermined evaluation function and the like, and assigns an instruction to the determined car. Is output (step S202).

  When the car that has received the allocation command has landed on the landing (Yes in step S203), the unloading determination unit 34 determines whether or not a passenger on the same destination floor waiting at the landing has been able to get on the car (step). S204). If the passenger cannot get in the car, it is determined that “there is no leftover” (Yes in step S204).

  Here, in the second embodiment, when it is determined that “there is an unloading”, the unloading number detection unit 36 detects the unloading number at the landing (step S205), and notifies the allocation control unit 33 to that effect. It is done. The allocation control unit 33 makes additional allocation to the car that can accommodate the unreserved number of passengers and responds to the landing (step S206).

  The detection of the number of unloaders in step S205 is performed based on the number of registrations for each destination floor and the change in the car load held in the management table 32a.

  More specifically, in the example of FIG. 6, it is assumed that the destination call for the 8th floor is registered by the passengers a and b at the landing on the 5th floor, and the first car 42a responds. Further, it is assumed that passengers A, B, C, and D are already in the car 42a.

  Since the process is complicated, if one platform responds to a destination floor and another destination floor is registered at the same platform, another platform is assigned to each floor platform. It shall respond.

  When the car 42a arrives at the landing on the fifth floor, it can be seen that there are two passengers waiting for the eighth floor from the number of registrations for each destination floor in the management table 32a. Therefore, for example, when an increase in load of about 120 kg is detected as 60 kg per passenger, it can be determined that two passengers a and b were able to get on. In addition, when the destination call is registered by pressing the handicapped person button 22 provided on the operation panel 13, the number of persons can be detected more accurately by considering the weight of the wheelchair.

  On the other hand, if the load increases around 60 kg, it can be determined that one of the passengers a and b is left behind. If there is no load change, it can be determined that two passengers a and b are left behind.

  In addition, when the passenger car 42a arrives at the landing on the fifth floor, some of passengers A, B, C, and D may get off there. In this case, if it is a standard car size, the passenger who gets into the car and the passenger who gets off do not act at the same time, and usually the passenger waiting at the landing boardes after the passenger gets off. Therefore, if the change in the load is observed with reference to the load value after the passenger gets off, it can be determined whether there is any unloading and the number of unloaded items.

  If it is determined that there is a leftover, the call information on the fifth floor stored in the management table 32a is held as it is, and the car 42b or the car 42c is taken into consideration in consideration of the number of leftovers at that time. Additional allocation of the fifth floor is made. In this case, for example, even if the car closest to the landing is the car 42b, if there is not enough room left in the boarding space of the car 42b, an additional allocation is made to the car 42c. Will be.

  The current number of passengers in the cars 42a, 42b, 42c can be detected from the respective load values. As another method, it is also obtained by learning the relationship between the number of registrations for each destination floor obtained by operating the operation panels 13a, 13b, 13c.

  When a car to be responded to the 5th floor hall is determined, guidance to that effect is given to the hall through the guide section 36. This is as described in FIG.

  In this way, by detecting not only the presence or absence of unloading but also including the number of unloaded items, the optimal car can be responded by additional allocation, and all passengers waiting at the landing can be reliably carried. Become.

  For example, when the number of unloading passengers is large and it is not sufficient to additionally allocate one car, additional allocation is made to another car to respond.

  In each of the above embodiments, the case has been described where three cars are group-managed, but the same applies to the case where more cars are group-managed.

  In addition, the number of passengers in the car is detected based on the load value. For example, a camera (not shown) is installed in the car, and the number of passengers is determined by analyzing the images taken by the camera. It may be detected.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments.
