Description

  Embodiments described herein relate generally to an elevator group management system including a landing destination floor registration device capable of registering a destination floor at a landing.

  Normally, when using an elevator, the user operates the UP direction (up direction) or DN direction (down direction) buttons installed on the landing area to register the hall call and responds to the registration floor. After getting on, perform operations such as registering a car call on the destination floor.

  On the other hand, if you have a device that can register the destination floor at the landing (referred to as a landing destination floor registration device), the user can register the destination floor in advance at the landing. No registration operation is required.

  Here, in a group management system having a plurality of elevators, when a user registers a destination floor at a landing, the number of a car that can be boarded is generally displayed on the landing destination floor registration device. The user can wait in front of the displayed unit, get on after arrival and move to the destination floor.

  However, if the traffic demand in the building becomes high, even if the unit number is displayed on the landing destination floor registration device, the unit may arrive in a state where it is almost full and cannot be boarded. In such a case, the user who could not get on has to register the destination floor again, which may be uncomfortable.

  Also, normally, when the boarding is not full and the boarding is not possible, for example, a “waiting for a while” waiting state such as “please wait for a while” is displayed on the landing destination floor registration device. However, it is preferable to refrain from waiting as much as possible because such a waiting display gives stress to the user waiting at the landing.

  The problem to be solved by the present invention is that when the user registers the destination floor at the landing, the display of the unit is displayed at a timing when the user can get on without displaying as much waiting as possible, so that the user can It is to provide an elevator group management system that can be efficiently carried without stress.

The elevator group management system according to the present embodiment is an elevator group management system that controls the operation of at least two or more units. In the elevator group management system, a display for registering a user's destination floor is installed at a landing on each floor. Based on the functioning hall destination floor registration device, the management table for storing the destination floor registered by the hall destination floor registration device and the hall call information including the registration floor, and the hall call information stored in the management table The allocation control means for selecting the optimal number of machines including the responses for the second and subsequent laps for the registered floor from among the above units, and the number of machines selected by the allocation control means on the first floor of the registered floor. When it is possible to respond, the fact that the corresponding machine responds to the above-mentioned landing destination floor registration device is displayed, and when the selected car can respond to the above registered floor after the second lap, Depending on the current response status; and a display control unit that displays that packed waiting state or the Unit on the car stop destination floor registration device responds, the display control means, Unit which is said selected above If you can respond to the registered floor after the second lap, if the unit is close to full and responding to the registered floor or if you are planning to respond, display the waiting status on the landing destination floor registration device It is characterized by.

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

(First embodiment)
FIG. 1 is a diagram showing the configuration of an elevator group management system according to the first embodiment, in which a configuration in which the operation of three elevators is group-controlled is shown. In addition, when there are a plurality of elevators, the term “unit” may be used. In addition, when it is simply called an elevator, it basically indicates a “car”.

  The single controllers 11a, 11b, and 11c are provided corresponding to the cars 12a, 12b, and 12c, and perform single unit control including drive control of a hoisting machine and door opening / closing control (not shown). . The cars 12a, 12b, 12c move up and down in the hoistway by driving a hoisting machine (not shown).

  On the other hand, at the landings on each floor, at least one landing destination floor registration device 13a, 13b, 13c... Is installed. The landing destination floor registration devices 13a, 13b, 13c,... Are devices for the user to register the destination floor at the landing on each floor, and are assigned to the operation units 14a, 14b, 14c,. It has display parts 15a, 15b, 15c... For displaying the number etc. Note that the destination floor registration method is generally based on the operation of the numeric keypad, but may be a method using, for example, a card reader or a wireless IC as long as registration is possible at the landing.

  When the destination floor registration is performed by the landing destination floor registration devices 13a, 13b, 13c... On each floor, two sets of information on the destination floor and the registered floor (the floor on which the destination floor registration operation has been performed) are combined into one set. The hall call information is output to the group management control device 20. The “destination floor” may be referred to as a “destination floor”, and the “registration floor” may be referred to as “occurrence floor”.

  When the group management control device 20 receives the hall call information, the operation information (car position, driving direction, door open / close state, etc.) of each car (car 12a, 12b, 12c) obtained from the single control devices 11a, 11b, 11c. ) To select an optimal number to which the hall call information is assigned from among the above numbers. A car to which hall call information is finally assigned is called an “assigned car”. When the assigned car is determined, the car number is displayed for a certain period of time on the landing destination floor registration device 13 installed on the registration floor of the landing call.

  The group management control device 20 is a device that comprehensively controls the operation of each unit, and is configured by a computer on which a CPU, a ROM, a RAM, and the like are mounted. In the present embodiment, the group management control device 20 includes a registration control unit 21, a response time calculation unit 22, an allocation control unit 23, and a display control unit 24. These are processing units executed by software on a microprocessor, and information can be exchanged between the respective units as shown in FIG.

  For convenience, the registration control unit 21, the response time calculation unit 22, the allocation control unit 23, and the display control unit 24 are all described in the group management control device 20. However, it is not always necessary to arrange them in the same device. Instead, they may be arranged in separate devices.

  The registration control unit 21 has a management table 21a as shown in FIG. 2, and hall call information registered by the hall destination floor registration devices 13a, 13b, 13c... The machine is registered in the management table 21a. As described above, the hall call information includes two pieces of information: the destination floor and the registered floor.

  In the example of FIG. 2, the following three pieces of information are registered in the management table 21a. Such information is deleted when the response of the assigned machine is completed.

・ The first floor is registered in the hall destination floor registration device 13 installed on the seventh floor, and assigned to Unit A.
-The first floor is registered with the hall destination floor registration device 13 installed on the fourth floor and assigned to Unit C.
・ The 10th floor is registered in the hall destination floor registration device 13 installed on the 1st floor, and assigned to Unit B and output.

  When the assigned number is determined, the destination floor information is output to the corresponding single control device 11 in the single control devices 11a, 11b, and 11c. As a result, the car call is automatically registered in the car 12 through the single controller 11. For example, if “first floor” is output as destination floor information, a car call for the first floor is automatically registered in the car 12.

  The response time calculation unit 22 calculates a response time serving as an allocation index for each unit for the hall call newly registered in the registration control unit 21. The response time is calculated based on the current car position, driving direction, door open / closed state, etc. in addition to the already registered hall call information.

  Here, in the present embodiment, as the “response time”, a time from when a user registers a destination floor to arrival at the destination floor (this is referred to as service time) is used. In other words, in the first time from when the user registers the destination floor until the unit arrives at the registration floor of the hall call, the first time from the registration floor until the unit arrives at the destination floor registered by the user. The time obtained by adding the time of 2 is calculated as the response time used in the allocation control. The first time is calculated as the user waiting time, and the second time is calculated as the user boarding time.

  Based on the hall call information stored in the management table 21a, the allocation control unit 23 selects the most appropriate car including the responses after the second lap with respect to the registered floor from among the above cars. Specifically, an evaluation value representing the optimality for the hall call information is calculated based on the average response time (average waiting time + average boarding time) calculated by the response time calculation unit 22 for all the cars. Assign and output the hall call information to the highest rated unit. In general, the lower the numerical value, the higher the evaluation value.

  The display control unit 24 displays the number selected by the assignment control unit 23 on the display unit 15 of the landing destination floor registration device 13 operated by the user. Specifically, if the first floor can respond to the registered floor, the landing destination floor registration device 13 displays that the corresponding car responds, and the selected car can respond to the registered floor on the second and subsequent laps. In such a case, a waiting state is displayed on the landing destination floor registration device 13 or a message indicating that the unit responds according to the current response status of the unit.

  The “response after the second round” means that the selected machine passes through the registered floor once and then reverses the direction at an arbitrary floor and responds to the same registered floor. On the other hand, “response in the first round” means that the selected car responds without passing through the registered floor.

  Here, with reference to FIG. 3 and FIG. 4, the relationship between the situation where the boarding is not possible and the display contents of the landing destination floor registration device 13 will be described.

  FIG. 3 is a diagram showing a situation where each unit is full and cannot be boarded. Now, assume that the user operates the landing destination floor registration device 13 on the seventh floor and registers the first floor as the destination floor.

  At this time, it is assumed that each unit is full as shown below.

Unit A: There are already passengers for the rated number of passengers (in this example, 5 people).
Unit B: When another user waiting on the same floor (7th floor in this example) gets on board, it becomes full.
Unit C: When another user who waits on the other floor (in this example, the fourth floor) gets on board, it becomes full.

  In such a case, although A machine passes without opening, since B machine and C machine open, there is a possibility that a user gets on by mistake. Further, in general, in a case such as Unit A, a full waiting state is displayed, so that the user is stressed.

  In the example of FIG. 3, the car is vacant when Unit C responds to the seventh floor, but the system (group management control device 20) is already in the fourth floor. Since it is managed including call registration, it is judged that it is almost full at this point.

  FIG. 4 is a diagram showing the contents displayed on the landing destination floor registration device 13, and display examples at normal time and when full are shown.

  The normal time is a state in which the user can get on the car that has landed on the registered floor in response to the first lap as usual. For example, as shown in FIG. 4A, it is assumed that the user registers the first floor as the destination floor by the landing destination floor registration device 13. When Unit A is determined as the selected unit and responds to the registered floor as usual, it is immediately indicated that Unit A responds to the display unit 15 of the landing destination floor registration device 13 as shown in FIG. Is displayed.

  On the other hand, when the selected car is almost full, the display is as shown in FIG. That is, for example, when Unit A is already almost full and there is no scheduled response on the registered floor, the display is the same as in normal time as shown in FIG. In this case, the first lap will be full and will respond in the second lap or later. The user waits without knowing that the crowd has passed, but since the unit that he can ride is displayed, there is less stress than when the waiting state is displayed.

  On the other hand, for example, when the C machine is the selected car and the C car is responding or is scheduled to respond, a waiting display is issued as shown in FIG. In other words, the door opens when Unit C responds to the registered floor, and therefore the user who registered the first floor may get on by mistake when displaying the selected number without displaying the waiting display. In order to prevent such an erroneous boarding, a waiting display is issued. In this case, the display as shown in FIG.

Next, the operation of the first embodiment will be described.
FIG. 5 is a flowchart showing the processing operation of the group management control device 20 in the first embodiment. Note that the processing shown in this flowchart is executed by the group management control device 20 which is a computer reading a predetermined program.

  When the user's destination floor is registered through the hall destination floor registration device 13 installed on an arbitrary floor (YES in step A11), hall call information including information on the destination floor and the registered floor is displayed in the group management control device 20. And stored in the management table 21a provided in the registration control unit 21 (step A12).

  When new hall call information is registered in the management table 21a, the allocation control unit 23 selects an optimum car from each car, including responses after the second lap for the registered floor, based on the hall call information. Select (step A13).

  Specifically, the average waiting time (first time) and average boarding time (second time) are obtained for all units through the response time calculation unit 22, and the response time (service time) obtained by adding these times is used as a base. Select the most suitable machine. In this case, the machine with the shortest response time (service time) is preferentially selected.

  Here, the allocation control unit 23 determines whether or not the selected car can respond in the first round (step A14). This is done by inferring from the registered information in the management table 21a when the selected machine stops on each floor, and checking whether it is close to full when responding in the first lap. .

  As explained in Fig. 3, when the number of users close to the rated number is already on board (example of Unit A), it is due to the ride of other users waiting on the same floor. This is a case where the space is full (example of Unit B), and a case where the space becomes full due to the riding of other users waiting on other floors (example of Unit C). If it is almost full, the selected car will respond after the second lap. At this time, only the most appropriate car is selected, and the hall call information is not assigned to the selected car. The “nearly full state” mentioned here includes a full state.

  If the selected car is not nearly full and can respond in the first lap as usual (NO in step A14), the allocation control unit 23 creates an operation schedule that can respond in the first lap (step A15). ). The allocation control unit 23 performs allocation output to the selected car according to the operation schedule and makes it respond to the registered floor, and the selected car responds to the display unit 15 of the registered destination floor registration device 13 through the display control unit 24. Is displayed (step A16).

  A display example at this time is shown in FIG. In this example, the fact that the A machine responds is displayed. Thereby, the user can get on at the time of the response of No. A and go to the destination floor (1F in this example).

  On the other hand, when the selected car is almost full and a response is made after the second lap (YES in step A14), the allocation control unit 23 creates an operation schedule that can respond after the second lap. (Step A17).

  At that time, the allocation control unit 23 refers to the management table 21a and determines whether or not the selected machine to respond in the second and subsequent laps is responding to the registration floor or is scheduled to respond (step A18). As a result, when there is no response and no response plan (NO in step A18), the allocation control unit 23 outputs the allocation to the selected car according to the operation schedule for the second and subsequent laps and responds to the registration floor, and displays The fact that the selected car responds is displayed on the display unit 15 of the registration destination hall registration device 13 through the control unit 24 (step A16).

  A display example at this time is shown in FIG. The fact that Unit A responds is displayed, but the first lap is actually full. The user waits without knowing that the first lap is full, but there is little stress because there is no waiting display.

  Further, when the response is being made or is scheduled to be answered (YES in step S18), the assignment control unit 23 registers through the display control unit 24 in order to prevent the user from getting on by mistake when the selected car responds. The display unit 15 of the floor destination floor registration device 13 on the floor displays that it is in a waiting state (step A19).

  A display example at this time is shown in FIG. In this example, a waiting state such as “It is busy. Please wait for a while” is displayed.

  If the selected car passes the registered floor and can be boarded with the next response (YES in step A20), the assignment control unit 23 performs assignment output to the selected car according to the operation schedule for the second and subsequent laps. In response to the registered floor, the display control unit 24 displays on the display unit 15 of the registered floor landing destination floor registration device 13 that the selected car responds (step A16).

  A display example at this time is shown in FIG. In this example, it is displayed that the C machine responds. As a result, the user can get on and go to the destination floor (in this example, 1F) the next time the Unit C responds.

  As described above, according to the first embodiment, when the user registers the destination floor at the landing, the optimal number of machines including the response of the second lap is selected, and the number of persons is filled according to the response status of the selected number of machines. A waiting state or a message indicating that the unit responds is displayed. Thereby, it becomes possible to display the number machine at a timing when the user can get on without displaying as much waiting as possible, and it is possible to carry it efficiently without causing stress to the user.

(Second Embodiment)
Next, a second embodiment will be described.

  In the first embodiment, since allocation control is always performed with priority given to operation efficiency, a waiting state may be displayed depending on the response status of the selected car. However, when such a waiting state is displayed when the number of users is low, it may be uncomfortable for some users. Therefore, in the second embodiment, the display of waiting for a full space is suppressed as much as possible when it is quiet.

  FIG. 6 is a diagram showing a configuration of an elevator group management system according to the second embodiment. In addition, the same code | symbol is attached | subjected to the same part as the structure of FIG. 1 in the said 1st Embodiment, and the description shall be abbreviate | omitted.

  In FIG. 6, the group management control device 20 includes a traffic situation determination unit 25 in addition to the configuration of the first embodiment. The traffic situation determination unit 25 determines whether the current traffic situation is a quiet time or a busy time. Here, “when it is quiet” means that there are few elevator users, and “when it is crowded” means that there are many elevator users.

  The allocation control unit 23 detects the presence / absence of a unit that can be displayed immediately on the display unit 15 of the registered destination floor registration device 13 when it is determined that the traffic situation determination unit 25 is not busy. In such a case, that number is selected as the optimum number, and the display control unit 24 displays that the number is responding. In addition, the allocation control unit 23, when it is determined that the traffic situation determination unit 25 is congested or when no unit that can be displayed immediately is detected, the second and subsequent laps for the registered floor from among the units. Select the optimal unit including the response.

  FIG. 7 is a flowchart showing the processing operation of the group management control device 20 in the second embodiment. As in the first embodiment, the processing shown in this flowchart is executed by the group management control device 20 that is a computer reading a predetermined program.

  When the user's destination floor is registered through the hall destination floor registration device 13 installed on an arbitrary floor (YES in step B11), hall call information including information on the destination floor and the registered floor is displayed in the group management control device 20. And stored in the management table 21a provided in the registration control unit 21 (step B12).

  Here, in the second embodiment, when the hall call information allocation control is performed, the traffic situation determination unit 25 determines whether it is a busy time or a busy time (step B13). When it is busy / crowded, it is judged based on the service time or time zone.

  The service time is a time from when a user registers a destination floor to arrival at the destination floor, and corresponds to a response time calculated by the response time calculator 22. The service time is obtained for each unit, and if the average value per unit time (for example, one hour) of these service times is a certain value or less, it is determined that the elevator is not busy. On the other hand, if the average value of the service time per unit time exceeds a certain value, it is determined that the elevator is busy.

  The time zone is a time zone in which quietness / congestion can be expected. For example, in the case of an office building, it is a work time zone, a work time zone, or the like. A quiet / congested time zone is set in advance based on the traffic demand of the building, and it is determined whether it is quiet or busy according to the time zone at that time.

  In times of congestion, it is necessary to carry a large number of users efficiently. Therefore, when it is determined that the traffic situation determination unit 25 is congested (NO in step B13), the allocation control unit 23 executes the same process as in the first embodiment (step B14).

  That is, as shown in Steps A13 to A20 of FIG. 5, the optimal unit including the response of the second lap is selected from each unit, and the waiting state is filled according to the response status of the selected unit Or it displays on the display part 15 of the hall destination floor registration apparatus 13 installed in the registration floor that the said machine responds. Thereby, a user can get on the number machine which can get on correctly, and can carry it efficiently.

  On the other hand, when the full waiting time is displayed when it is quiet, some users may feel uncomfortable, so it is desirable not to display the full waiting time as much as possible. Therefore, if it is determined that the traffic situation determination unit 25 is not busy (YES in step B13), the allocation control unit 23 immediately displays on the display unit 15 of the landing destination floor registration device 13 installed on the registration floor. The presence / absence of a possible machine is detected (step B15). If a corresponding number is detected (YES in step B16), the allocation control unit 23 selects the number as the optimum number (step B17), and the number responds to the display control unit 24. A message is displayed (step B18).

  The response car displayed at this time is a car that can be displayed immediately, and is not necessarily efficient in operation when viewed from the whole elevator system. In other words, if there are many users on the same destination floor, the same unit is assigned to give priority to operation efficiency. On the other hand, when priority is given to immediate display, even a user on the same destination floor may be assigned a different unit, which may cause a long wait. However, when it is quiet, it is preferable to display the number of vehicles that can be boarded early to the user even if the efficiency is somewhat low.

  In addition, when the applicable number machine is not detected in the said step B16, the allocation control part 23 will perform the process similar to the said 1st Embodiment (step B14).

  As described above, according to the second embodiment, priority can be given to efficient operation during busy times, and priority can be given to immediate display during periods of quietness, so that it is possible to display appropriate units according to traffic conditions at that time. It can be carried without giving stress to users waiting at the landing.

  In each of the above embodiments, the group management system having three units (elevators) has been described as an example. However, three or more units may be used, and in short, group management control is performed on at least two units. Any configuration can be used.

  According to at least one embodiment described above, when a user registers a destination floor at a landing, by displaying the unit at a time when the user can get on without displaying as much waiting as possible, It is possible to provide a group management system for elevators that can be carried efficiently without giving stress to a person.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
