It is a block diagram of the elevator system to which the group management apparatus of an elevator in Embodiment 2 is applied. An outline of the operation of the elevator group management device in the second embodiment will be described.

The embodiments will be described with reference to the accompanying drawings. In each figure, the same or corresponding parts are designated by the same reference numerals. The duplicate description of the relevant part will be simplified or omitted as appropriate.

Embodiment 1.
FIG. 1 is a configuration diagram of an elevator system to which the elevator group management device according to the first embodiment is applied.

In the elevator system of FIG. 1, the elevator platform 1 is provided on each floor of the building. A plurality of cars are provided inside a hoistway (not shown). In FIG. 1, a first car 2a and a second car 2b are shown.

The display device 3 is provided at the landing 1. For example, the display device 3 is provided on the wall surface of the landing 1. The display device 3 is provided so as to be able to display information.

For example, the plurality of car control devices are provided in a machine room (not shown). For example, the plurality of car control devices are provided at the upper or lower part of the hoistway. The plurality of car control devices are provided corresponding to each of the plurality of cars. In FIG. 1, the first car control device 4a is provided corresponding to the first car 2a. The second car control device 4b is provided corresponding to the second car 2b.

The user arrival detection device 5 is provided in the vicinity of each landing 1. For example, the user detection device includes a camera and a video processing unit. The camera is provided so as to be able to capture the traffic of a person near the elevator platform 1. The image processing unit detects that the person has arrived at the landing 1 as a user when the area of the person is extracted from the image of the camera and the person heading for the landing 1 is extracted.

For example, the group management device 6 is provided in the machine room. For example, the group management device 6 is provided at the upper or lower part of the hoistway. The group management device 6 includes a destination call automatic registration unit 6a, a call allocation unit 6b, a user number storage unit 6c, and an allocation candidate basket determination unit 6d.

Whenever the user arrival detection device 5 detects the arrival of the user at the landing 1, the destination call automatic registration unit 6a sets the floor of the landing 1 as the boarding floor and the predetermined specific floor as the getting-off floor. Register the destination call to be.

The call allocation unit 6b allocates the destination call to an appropriate car from the car candidates. For example, the call allocation unit 6b determines as an appropriate car a car that is scheduled to arrive at the boarding floor of the destination call in the shortest time. For example, the call allocation unit 6b comprehensively determines from a plurality of factors such as the influence on other users and energy efficiency to determine an appropriate car. The call allocation unit 6b transmits the destination call information to the car control device corresponding to the determined car.

Each time the call allocation unit 6b allocates an appropriate car to the destination call, the user number storage unit 6c stores information on the number of users of the plurality of cars assuming that the user is a user from the boarding floor to the getting-off floor in the car. Remember. When the car actually travels from the boarding floor corresponding to the destination call and arrives at the getting-off floor, the user number storage unit 6c limits the number of users from the boarding floor to the getting-off floor by only one. Erase from memory.

When the destination call automatic registration unit 6a registers the destination call, the allocation candidate car determination unit 6d determines the candidate of the car to which the destination call is assigned. For example, the allocation candidate car determination unit 6d confirms the number of users in each car when traveling from the boarding floor to the disembarking floor of the destination call, and at least excludes the cars that have reached the capacity. Determined as a candidate for the basket to be assigned to the destination call.

For example, the allocation candidate car determination unit 6d has information on the boarding floor and the getting-off floor corresponding to the destination call, the current position and running stop schedule of each car obtained from a plurality of car control devices, and the number of users storage unit 6c. The car candidates are decided based on the number of users of each car in.

Specifically, the allocation candidate car determination unit 6d determines the traveling direction after the car arrives at the boarding floor from the boarding floor and the getting-off floor corresponding to the destination call. When it is assumed that the allocation candidate car determination unit 6d allocates each car to the boarding floor and the traveling direction, each car when traveling in the same direction based on the information of the user number storage unit 6c. Estimated by the user of. The allocation candidate car determination unit 6d excludes the cars whose number of users reaches a preset number from the car candidates. For example, the allocation candidate car determination unit 6d excludes a car whose number of users reaches 80% of the capacity from the car candidates.

In addition, even if the number of users does not reach the preset number when the allocation candidate car determination unit 6d arrives at the boarding floor, the number of users further increases on the subsequent stop floor to the preset number. Exclude reach from car candidates. For example, if the specific floor is the 1st floor, the capacity of the 1st basket 2a is 3, 2 users from the 5th floor to the 1st floor, and 1 user from the 3rd floor to the 1st floor, 3 From the first floor to the first floor, there are three users of the first basket 2a. When destination calls from the 5th floor to the 1st floor are registered in this state, the allocation candidate car determination unit 6d excludes the first car 2a from the car candidates.

Each of the plurality of car control devices controls the operation of the car according to the destination call from the group management device 6. Specifically, the car control device controls the running of the car and the opening / closing of the door according to the destination call. More specifically, the car control device drives the car toward the boarding floor corresponding to the destination call. After the car has stopped on the boarding floor, the car control device opens the door. After a certain period of time, the car controller closes the door. The car control device drives the car toward the drop-off floor corresponding to the destination call. After the car has stopped on the disembarkation floor, the car controller opens the door. After a certain period of time, the car controller closes the door.

Next, the outline of the operation of the group management apparatus 6 will be described with reference to FIG.
FIG. 2 illustrates an outline of the operation of the elevator group management device according to the first embodiment.

In step S1, the group management device 6 determines whether or not the user arrival detection device 5 has detected the arrival of the user at the landing 1. If the user arrival detection device 5 has not detected the arrival of the user at the landing 1 in step S1, the group management device 6 repeats the operation of step S1. When the user arrival detection device 5 detects the arrival of the user at the landing 1 in step S1, the group management device 6 performs the operation of step S2.

In step S2, the group management device 6 registers a destination call from the floor of the landing 1 to a specific floor. After that, the group management device 6 performs the operation of step S3. In step S3, the group management device 6 determines a plurality of car candidates to be assigned to the destination call from among the plurality of cars. After that, the group management device 6 performs the operation of step S4. In step S4, the group management device 6 assigns an appropriate car to the destination call from among a plurality of car candidates. After that, the group management device 6 performs the operation of step S5. In step S5, the group management device 6 updates the information on the number of users of the plurality of cars as if they are users from the floor of the landing 1 in the car to the specific floor.

According to the first embodiment described above, in the elevator in which a plurality of cars are managed as a group, in the group management device 6, the user arrival detection device 5 is sent to the user's landing 1 by the destination call automatic registration unit 6a. Registers a destination call from the first floor of the platform to a specific floor each time the arrival of the vehicle is detected. The group management device 6 determines an appropriate car candidate to be assigned to the destination call by the user number storage unit 6c and the allocation candidate car determination unit 6d. Therefore, even if there is no operation for registering the destination call, the user can be moved more reliably to a specific floor without performing a special operation. For example, in a situation where the disembarkation floor is fixed, all users can move without any operation without having to equip a personal authentication device or the like. Further, when a user is detected, a plurality of cars can be appropriately assigned according to the number of users without specifying the group for each destination floor.

It should be noted that the function of the destination call automatic registration unit 6a or the user number storage unit 6c may be disabled in a time zone other than the specific time zone. In this case, the functions of the destination call automatic registration unit 6a and the user number storage unit 6c become effective in a specific time zone. For example, in the case of a hotel, the lobby floor may be a specific floor only in the morning. For example, in the case of an office, the dining room floor may be set as a specific floor only during the day.

If it is the upper floor of the condominium, the floor where the entrance / exit of the condominium exists may be a specific floor at all times.

Further, the specific floor may be any floor that is well known to elevator users. In this case, a specific floor may be changed depending on the time zone and the day of the week.

Further, in the call allocation unit 6b, the display device 3 may display the number of destination calls assigned to each car as the number of people available from the floor of the landing 1. In this case, even if multiple cars arrive on the same floor, it is possible to clarify how many people should board each car. For example, the number of people that can be used at the next arrival or during arrival may be displayed near the door of the platform 1 of each car. In these cases, it is possible to use an appropriate car without causing trouble to users on other floors.

Further, the detection range of the user arrival detection device 5 may be clearly indicated on the floor surface of the landing 1, and the destination call may be automatically registered only for the person who has passed the detection range. Further, a plurality of user arrival detection devices 5 may be provided on each floor, and destination calls corresponding to different destination floors may be automatically registered for each detection by the plurality of user arrival detection devices 5.

In the allocation candidate car determination unit 6d, a car to be excluded from the candidates may be determined by another function. For example, when the number of stops on the middle floor while traveling in a certain direction is determined and a new destination call is assigned, the car whose number of stops exceeds a preset number may be excluded from the car candidates. In this case, the orbital time of each car can be made uniform.

Next, an example of the group management device 6 will be described with reference to FIG.
FIG. 3 is a hardware configuration diagram of the elevator group management device according to the first embodiment.

Each function of the group management device 6 can be realized by a processing circuit. For example, the processing circuit comprises at least one processor 100a and at least one memory 100b. For example, the processing circuit comprises at least one dedicated hardware 200.

When the processing circuit includes at least one processor 100a and at least one memory 100b, each function of the group management device 6 is realized by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in at least one memory 100b. At least one processor 100a realizes each function of the group management device 6 by reading and executing a program stored in at least one memory 100b. At least one processor 100a is also referred to as a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, and a DSP. For example, at least one memory 100b is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.

If the processing circuit comprises at least one dedicated hardware 200, the processing circuit may be implemented, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. To. For example, each function of the group management device 6 is realized by a processing circuit. For example, each function of the group management device 6 is collectively realized by a processing circuit.

For each function of the group management device 6, a part may be realized by the dedicated hardware 200, and the other part may be realized by software or firmware. For example, the function of the destination call automatic registration unit 6a is realized by a processing circuit as dedicated hardware 200, and for functions other than the function of the destination call automatic registration unit 6a, at least one processor 100a is in at least one memory 100b. It may be realized by reading and executing the stored program.

In this way, the processing circuit realizes each function of the group management device 6 by hardware 200, software, firmware, or a combination thereof.

Although not shown, each function of the car control device is also realized by the same processing circuit as the processing circuit that realizes each function of the group management device 6.

Embodiment 2.
FIG. 4 is a configuration diagram of an elevator system to which the elevator group management device according to the first embodiment is applied. The same or corresponding parts as those of the first embodiment are designated by the same reference numerals. The explanation of this part is omitted.

In the second embodiment, the plurality of actual user estimation devices are provided so as to be able to estimate the number of users who are actually in the plurality of cars. For example, the first actual user estimation device 7a is provided so as to be able to estimate the number of users who are actually in the first car 2a. For example, the second actual user estimation device 7b is provided so as to be able to estimate the number of users actually in the second car 2b.

For example, each of the plurality of actual user estimation devices is a scale. In this case, each of the plurality of actual user estimation devices estimates the number of users actually in the car based on the comparison result between the preset weight per person and the load of the current car.

For example, each of the plurality of actual user estimation devices includes a camera and a video processing unit. In this case, the number of users actually in the car is estimated by detecting the person area from the image inside the car and calculating the floor area occupancy rate.

The group management device 6 includes a fullness detection unit 6e.

The occupancy detection unit 6e acquires information on the number of users actually in the car from a plurality of actual user estimation devices. When the number of users actually in the car exceeds a preset number when the car departs, the occupancy detection unit 6e is on the floor of the landing 1 in the same direction as the departure direction of the car. The process of allocating the destination call assigned to the car on the floor between the above and the specific floor to another car is performed. At this time, the occupancy detection unit 6e excludes the car from the car candidates for the destination call until the number of users in the car becomes less than or equal to the preset number.

Next, the outline of the operation of the group management apparatus 6 will be described with reference to FIG.
FIG. 5 illustrates an outline of the operation of the elevator group management device according to the second embodiment.

The operation of FIG. 5 is performed out of synchronization with the operation of FIG. In step S11, the group management device 6 determines whether or not each of the plurality of cars is full. For example, the group management device 6 determines that the car is full when the number of people inside the car reaches 80% of the capacity. If all the cars are not full in step S11, the group management device 6 performs the operation of step S11. If any of the cars is full in step S11, the group management device 6 performs the operation of step S12.

In step S12, the group management device 6 corrects the information on the number of users of the car. For example, the group management device 6 corrects the number of users of the car to the number of people when it is determined that the car is full. Specifically, the basket is full of 3 people, 1 person is assigned from the 5th floor to the 1st floor, 1 person is assigned to the 4th floor to the 1st floor, and 1 person is assigned to the 2nd floor to the 1st floor. If the car is full when departing from, it is unclear whether the car actually got in two passengers from the 5th floor or two passengers from the 4th floor. .. In this case, the group management device 6 corrects when two users get on the car from the 4th floor to the 1st floor. As a result, the car is treated as full between the 4th floor and the 1st floor.

After that, the group management device 6 performs the operation of step S13. In step S13, the group management device 6 changes the assignment of a part of the destination call assigned to the car. Specifically, the group management device 6 temporarily performs all of the destination calls already assigned to the car, in which the floor between the floor where the car departs and the specific floor is the boarding floor. Cancel. After that, the group management device 6 re-registers these destination calls. At this time, the cars for which fullness is detected are excluded from the car candidates to which these destination calls are assigned. As a result, these destination calls are assigned to another car if the car is full. After that, the group management device 6 ends the operation.

According to the second embodiment described above, when the number of users actually in the car exceeds a preset number when the car departs, the direction is the same as the departure direction of the car. In, the destination call assigned to the car on the floor between the floor of the landing 1 and the specific floor is assigned to another car. Therefore, the influence of the detection accuracy of the arrival of the user at the landing 1, the number of users who use each car when a plurality of cars arrive at the landing 1, and the number of users who actually board each car. However, it is possible to suppress the occurrence of users who cannot get into the car.

For example, if the number of destination calls assigned to each car cannot be displayed on the display device 3 as the number of people available from the floor of the landing 1, the number of destination calls assigned to each car is used. It is possible to avoid unnecessary car stop even if the number of people available from the floor of the landing 1 is displayed on the display device 3 or ignored.

Even if it is determined in step S11 whether or not the car is full, it is determined based on the total of the number of users who are actually in the car and the number of users who are planning to ride in the car from other floors. good. In this case, in step S13, the process of allocating the destination call assigned to the car to another car on the floor between the floor of the landing 1 and the specific floor until the total becomes less than or equal to the preset number. Is done. In this case, the timing of determination of allocation can be advanced.
