The vehicle allocation determination unit 102 determines the optimum number of vehicles to be dispatched from the floor where the landing call was made and the distributed standby floor where the

vehicles

131a, 131b, 131c, 131d are waiting.

The learning unit 103 detects the number of people using the elevator on a daily basis and learns the congestion situation. The learning unit 103 sets the congested floor by learning the traffic flow pattern and determining which mode the current traffic flow pattern is. Distributed zones and distributed floors are set according to this crowded floor. The learning unit 103 includes means for setting a plurality of distributed zones and means for setting distributed floors on which elevators are placed on standby in a distributed manner.

The distributed control unit 104 executes a control process of allocating an elevator car in advance to a congested floor recognized by the learning unit, a set distributed zone, or a distributed floor. In this embodiment, control is performed with the power supply floor as one of the distributed floors.

When the landing call is registered and the optimum elevator is determined, the guidance command unit 105 lights up the lantern installed at the landing and guides the user to arrive at the elevator. The guidance command unit 105 may be installed in the

unit control devices

135a, 135b, 135c, 135d.

The unit abnormality detection unit 107 (abnormality detection means) receives an abnormality of each unit (unit 1 elevator 130a, unit 2 elevator 130b, unit 3 elevator 130c, unit 4 elevator 130d) from the

unit control devices

135a, 135b, 135c, 135d. And detect an abnormal condition. The unit determined to be abnormal by the unit abnormality detection unit 107 is excluded from the vehicle allocation target of the vehicle allocation determination unit 102. In this embodiment, the abnormality of the

power feeding devices

132a, 132b, 132c is also included in the unit abnormality. The stop floors (1st floor, 7th floor, 12th floor) in which the

power supply devices

132a, 132b, 132c are set are referred to as power supply floors. The unit abnormality detection unit 107 (abnormality detection means) detects individual abnormalities of the power supply device on each of the power supply floors of the

power supply devices

132a, 132b, 132c (1st floor, 7th floor, 12th floor of the power supply device 132a, power supply device). 132b 1st floor, 7th floor, 12th floor, power supply device 132c 1st floor, 7th floor, 12th floor). In the Unit 1 abnormality detection unit 107 (abnormality detection means), in the

power supply devices

132a, 132b, 132c of the Unit 1 elevator 130a, the Unit 2 elevator 130b, and the Unit 3 elevator 130c, the power supply devices installed on all floors failed. In that case, it is excluded from the target of vehicle allocation. For example, if the power supply devices 132a on all floors of the Unit 1 elevator 130a break down, it is determined that there is an abnormality, and the Unit 1 elevator 130a is excluded from the vehicle allocation target of the vehicle allocation determination unit 102.

The power supply floor setting unit 108 determines whether the elevator is a unit elevator that requires power supply due to the low remaining charge of the battery, and if charging is required, determines which stop floor the

power supply devices

132a, 132b, 132c are set to. to decide. Further, in the

power supply devices

132a, 132b, 132c of the Unit 1 elevator 130a, the Unit 2 elevator 130b, and the Unit 3 elevator 130c, which are non-contact power supply type elevators, a part of the power supply is supplied by the Unit abnormality detection unit 107 (abnormality detection means). When the power supply device installed on the floor is determined to be abnormal (malfunction), when selecting the elevator to be assigned to the target distributed floor where the

power supply devices

132a, 132b, 132c determined to be abnormal (malfunction) are installed. Excludes Unit 1 elevator 130a, Unit 2 elevator 130b, and Unit 3 elevator 130c for which the

power supply devices

132a, 132b, and 132c are determined to be abnormal. For example, if the power supply device 132a on the 7th floor of the Unit 1 elevator 130a, which is a non-contact power supply type elevator, is determined to be abnormal (malfunction), the Unit 1 elevator 130a is excluded from the selection targets of the elevators having the 7th floor as the distributed floor. To do. However, although the 7th floor of the Unit 1 elevator 130a is excluded from the distribution floors, the elevators whose distribution floors are the 1st and 12th floors, which are other power supply floors, are selected.

The power supply floor setting unit 108 serves as a selection means for selecting an elevator to be assigned to a distributed floor from a plurality of elevators subject to group management control based on the detection result of the unit abnormality detection unit 107 (abnormality detection means). It has a function.

In addition, the power supply floor setting unit 108 (selection means) excludes the Unit elevator from the vehicle allocation target when the power supply devices on all floors of the power supply floor break down.

Next, the distributed standby of the elevator will be described with reference to FIGS. 2 to 5. FIG. 2 is a diagram showing an example of a distributed zone table when distributed zones are given to three elevators. FIG. 3 is a diagram showing an example of a distributed zone table of an elevator when commuting. FIG. 4 is a diagram showing an example of a distributed zone table of an elevator at lunch time. FIG. 5 is a diagram showing an example of an elevator distributed zone table at the time of a meeting.

In FIGS. 2 to 5, in this embodiment, the elevators of Units 1 to 4 (4 units) are installed in the building on the 12th floor. The entrance is on the 1st floor, the conference room is on the 11th floor, and the cafeteria is on the 12th floor. The other blank floors are residential floors. Power supply devices are installed on the 1st, 7th, and 12th floors of each unit.

In a building with multiple elevators installed, multiple cars will be distributed on each floor so that the cars can arrive as soon as possible in response to a call from the user. The floor where the cars are distributed is called the distributed floor. The distributed floors are appropriately changed according to the traffic flow pattern of the elevator. If there is no landing call, each car will stand by on its own distributed floor, which is set according to the traffic flow pattern. In the case of a non-contact power supply type elevator, the floor set as the distributed floor is generally assigned to the power supply floor on which the power supply device is installed. The car charges the battery while stopped on the power supply floor. In addition, a distributed zone is assigned to each elevator, and when a landing call is made from the corresponding distributed zone, the car of the Unit elevator assigned to the distributed zone in preference to the other Unit elevators will be assigned. Express to the floor where you received the call.

In FIG. 2, in the situation where the expected number of people on each floor is evenly allocated, three of the four elevators are assigned to distributed zones Z1 to Z3 as targets of distributed control, and one of them is assigned. No distributed zone is assigned. For example, the Unit 1 elevator to the Unit 3 elevator are assigned distribution zones Z1 to Z3, respectively, and correspond to a landing call. In FIG. 2, the car of the Unit 1 elevator stands by on the 1st floor, which is a distributed floor, and corresponds to the landing calls on the 1st to 4th floors as the distributed zone Z1. The platform of the Unit 2 elevator will be on standby on the 7th floor, and will be called as a distributed zone Z2 on the 5th to 8th floors. The platform of the Unit 3 elevator will be on standby on the 12th floor, and will be called as a distributed zone Z3 on the 9th to 12th floors.

In Fig. 3, when going to work, the passengers getting on and off the elevator change, so the settings of the distributed floors and distributed zones are changed. When going to work, a traffic flow pattern appears in which passengers go from the entrance on the 1st floor to the residential floor of the office, so the settings of the distributed floors and distributed zones are changed so that the elevator cars are concentrated on the 1st floor. From the traffic flow pattern in the elevator, it is judged whether or not it is time to go to work. For the threshold value listed below the table, the value obtained by dividing the total value of the predicted number of people on each floor by the number of elevators is used. In the case of FIG. 2, the total value of the predicted number of people is 840, and this is divided by 4 of the number of elevators to calculate the threshold value 210. The threshold value is used for setting the distribution floor, which will be described later.

When going to work as shown in Fig. 3, the distributed floors of the elevators of Units 1 to 3 and the distributed zones Z1 to Z3 are set on the 1st floor, and the cars are distributed intensively to the 1st floor. For the platform of the Unit 4 elevator, the distributed floor is set to the 7th floor, and the 3rd to 12th floors are designated as the distributed zone Z4 to correspond to the platform calls on the 3rd to 12th floors.

At lunch time shown in FIG. 4, a traffic flow pattern that goes back and forth between the entrance on the first floor and the dining room floor, and between the living floor and the dining room floor appears. Set up on the floor to prepare for the transportation of passengers who have finished their meals. The 1st to 11th floors will be shared by the elevators of Units 2 to 4. For the platform of the Unit 2 elevator, the distributed floor is set to the 1st floor, and the distributed zone Z1 is set to the 1st to 3rd floors to correspond to the landing calls on the 1st to 3rd floors. The Unit 3 elevator has a distributed floor on the 7th floor and a distributed zone Z2 on the 4th to 7th floors, and responds to landing calls on the 4th to 7th floors. For the elevator of Unit 4, the distributed floor is set to the 9th floor, the distributed zone Z3 is set to the 8th to 11th floors, and the landing calls on the 8th to 11th floors are supported. Since the Unit 4 elevator is powered by the tail code, the 9th floor, which is not affected by the power supply floor, is a distributed floor.

At the time of the meeting shown in Fig. 5, a traffic flow pattern appears from the residential floor to the 11th floor where the meeting room floor is located, so for example, the 1st to 10th floors are shared by the elevators of Units 2 to 4. For the Unit 2 elevator, the distributed floor is set to the 1st floor, and the distributed zone Z1 is set to the 1st to 3rd floors to respond to landing calls on the 1st to 3rd floors. The Unit 3 elevator has a distributed floor on the 7th floor and a distributed zone Z2 on the 4th to 7th floors, and responds to landing calls on the 4th to 7th floors. The Unit 4 elevator has a distributed floor on the 9th floor and a distributed zone Z3 on the 8th to 10th floors, and responds to landing calls on the 8th to 10th floors. The distributed floors of the Unit 1 elevator car and the distributed zone Z4 will be set on the 11th to 12th floors to prepare for the transportation of passengers who have finished the meeting.

Next, the method of setting the distributed floor will be described with reference to FIGS. 6 to 12. FIG. 6 is a processing flow of an elevator operation management processing system according to an embodiment of the present invention. In FIG. 6, the operation management system 100 sets a distributed floor from the traffic flow pattern of the elevator (step S200), grasps the failure state of each unit elevator, and sets the unit elevator to be the target of distributed control (step S300). Then, the distribution floor of the unit elevator to be the target of the distribution control is selected and set (step S400), and the distribution command is output to each unit elevator (step 500).

Next, the details of each step S200 to S500 will be described with reference to FIGS. 7 to 12. FIG. 7 is a processing flow for setting the distributed floor according to the embodiment of the present invention. In FIG. 7, the learning unit 103 of the operation management system 100 determines which traffic flow mode the current traffic flow pattern corresponds to, and the number of distributed zones of the elevator to be controlled from the determined current traffic flow mode. , Congested floors and distributed floors are set (step S201). As the traffic flow mode, a plurality of combinations of the number of distributed zones, congested floors, and distributed floors are prepared, and an arbitrary traffic flow mode is selected and set from the detected traffic flow patterns.

Next, the power supply floor setting unit 108 of the operation management system 100 determines whether or not there is a unit elevator (contactless power supply type) that requires power supply as the elevator to be controlled among the plurality of elevators (step S202). If there is a unit elevator that requires power supply (YES in step S202), the power supply floor is specified for each unit elevator (step S203). In step S202, if there is no unit elevator (contactless power supply type) that requires power supply (NO in step S202), the process proceeds to step S204.

In step S204, the power supply floor setting unit 108 determines whether or not the congested floor of each distributed zone and the power supply floor match, and if they match (YES in step S204), the congested floor is set to the distributed floor. (Step S205). For example, in FIG. 4, the crowded floors are the 1st floor and the 12th floor, and these are the distributed floors, and the 1st floor and the 12th floor are the power supply floors, and the crowded floors and the distributed floors are the same. In this embodiment, when there is a non-contact power supply type elevator (unit elevator that requires power supply), the distributed floor is basically a power supply floor, which is a non-contact power supply type elevator and is a normal non-contact power supply type elevator or non-contact power supply type elevator. Elevators that are not contact-powered are targeted for distribution, and if there is no non-contact-powered elevator, distributed control is performed by elevators that are not contact-powered.

In step S204, if the unit elevator (non-contact power supply type) that requires power supply does not exist, the power supply floor setting unit 108 determines that there is no power supply floor (YES in step S204), and makes the congested floor a distributed floor. (Step S205).

In step S204, if the congested floor of each distributed zone and the power supply floor do not match (NO in step S204), the power supply floor setting unit 108 proceeds to step S206 and determines whether or not the congested floor is congested above the threshold value. To do. The threshold value here is the threshold value described with reference to FIGS. 3 to 5. If the congestion floor is more than the threshold value (YES in step S206), the distribution floor in the distribution zone is designated as the floor where the power supply floor and the congestion floor match (step S207).

In step S206, when the congestion floor is not more than the threshold value (NO in step S206), the power supply floor setting unit 108 gives priority to the storage of electricity in the battery and designates the power supply floor as the distributed floor (step S208).

Next, the process of the power supply floor setting unit 108 in step S203 will be described with reference to FIG. FIG. 8 is a processing flow of the power supply floor setting unit according to the embodiment of the present invention.

In step S210, the power supply floor setting unit 108 determines whether or not there is a unit elevator (contactless power supply type) that requires power supply because the battery charge capacity is insufficient and there is a unit elevator that requires power supply. To do. When there is a Unit elevator that requires power supply (YES in step S210), it is determined whether or not the power supply device is abnormal (step S211). The unit abnormality detection unit 107 is used to determine the abnormality of the power feeding device. For example, the unit abnormality detection unit 107 monitors the charging status of the battery when the car stops at each power supply floor and stops at each power supply floor, and if the charge amount per unit time is equal to or less than a predetermined value, the battery charge status is monitored. Judge that the power supply device on the stop floor is abnormal and store it.

When the power supply device on a certain stop floor is determined to be abnormal (YES in step S211), the power supply floor setting unit 108 acquires the floor information set in advance or the power supply device is operating normally from the unit abnormality detection unit 107. Then, the floor on which the power supply device is determined to be abnormal is regarded as an abnormal floor and excluded from the target of the power supply floor (distributed floor) (step S212). That is, the non-contact power supply type elevator determined to be an abnormal floor is excluded from the selection target of the elevator that allocates this abnormal floor as a distributed floor. In determining the abnormality of the power supply device in step S211, the floor on which the power supply device is determined to be abnormal is set as the abnormal floor, and the floor on which the other power supply devices are operating normally is the target of the power supply floor (distributed floor).

In step S210, the power supply floor setting unit 108 ends the process when the battery charge capacity is sufficient and there is no unit elevator that requires power supply (NO in step 210).

In step S211, if there is no abnormality on the floor on which the power supply device is installed (NO in step S211), the power supply floor setting unit 108 sets in advance or provides floor information in which the power supply device is operating normally to the unit abnormality detection unit. The floor obtained from 107 and determined to be normal is set as the power supply floor (distributed floor) (step S213). In step S213, in determining the abnormality of the power supply device, the floor where the power supply device is determined to be abnormal is set as the abnormal floor, and the floor where the other power supply devices are determined to be operating normally is set as the power supply floor (distributed floor). Includes steps.

In this embodiment, in a non-contact power supply elevator equipped with a power supply device, when an abnormality in the power supply device is detected and the power supply device is determined to be abnormal, the target in which the power supply device determined to be abnormal is installed. One of the features of selecting the elevators to be assigned to the distributed floors is that the power supply device has a process of excluding the non-contact power supply type elevators that are judged to be abnormal from the selection target. According to this embodiment, the power supply floor in which the abnormality of the power supply device is detected is excluded from the selection target so that the non-contact power supply type elevator is not assigned as the distributed floor. It is possible to prevent the battery from becoming insufficiently charged.

Next, step S300 for setting the unit to be distributed will be described. FIG. 9 is a processing flow for setting the distributed target unit according to the embodiment of the present invention. In FIG. 9, the power supply floor setting unit 108 sets the unit elevator that can be controlled as a dispersion target from the detection result of the unit abnormality detection unit 107 (step S301). The processing of the unit abnormality detection unit 107 will be described later.

In step S302, the power supply floor setting unit 108 determines whether or not there is a unit elevator (contactless power supply type) that requires power supply among the elevators subject to distributed control, and the unit elevator that requires power supply exists. In the case (YES in step S302), the power supply floor setting unit 108 specifies the power supply floor for each unit elevator and acquires the information of the unit unit elevator to be supplied (step S303), and for each distributed floor, The number of vehicles that can be dispatched and the number of units that can be dispatched are detected (step S304).

In step S302, the power supply floor setting unit 108 proceeds to step S304 when there is no unit elevator (non-contact power supply type) that requires power supply among the elevators subject to distributed control (NO in step S302). The processing of the power supply floor setting unit 108 is as shown in FIG. 8, and the non-contact power supply type elevator provided with the abnormal floor having an abnormality in the power supply device is excluded from the elevators to be selected having the abnormal floor as the distributed floor.

Next, the processing of the unit abnormality detection unit 107 will be described. FIG. 10 is a processing flow of the unit abnormality detection unit according to the embodiment of the present invention.

The unit abnormality detection unit 107 determines whether each unit elevator is in maintenance operation or in an abnormal state (step S310). If any of the elevators is in maintenance operation or in an abnormal state (YES in step S310), the elevator determined to be abnormal is excluded from the elevators that can be dispatched (step S311). By this process, in step S301 of FIG. 9, information on the controllable unit elevator is set. Then, the power supply floor setting unit 108 (selection means) excludes the unit elevator determined to be abnormal from the unit elevators that can be dispatched based on the result of the unit abnormality detection unit 107 (abnormality detection means), and starts from the normal unit elevator. Select the No. 1 elevator that can be dispatched.

In step S310, if any of the elevators is not in maintenance operation or in an abnormal state (NO in step S310), it is determined whether or not there is an elevator that requires power supply because the battery charge capacity is insufficient. (Step S312).

If there is a unit elevator that requires power supply in step S312 (YES in step S312), the process proceeds to step S313 to determine whether or not one or more power supply devices of the corresponding unit elevator are operating. If one or more power supply devices of the corresponding unit elevator are operating (YES in step S313), the process is terminated assuming that there is no unit elevator to be excluded from the unit elevators that can be dispatched. When all the power supply devices of the corresponding unit elevators are not operating (NO in step S313), the target unit elevators are excluded from the unit elevators that can be dispatched (step S311).

In step S312, if there is no unit elevator that requires power supply (NO in step S312), the process is terminated assuming that there is no unit elevator to be excluded from the unit elevators that can be dispatched.

According to this embodiment, if any one of the plurality of elevators is in maintenance operation, is in an abnormal state, or all of the power supply devices are out of order, the target elevator is excluded from the elevators that can be dispatched. Therefore, it is possible to smoothly dispatch the vehicle to the floor where the landing was called by operating with the normal Unit elevator.

Next, step S400 of the distributed machine selection setting will be described. FIG. 11 is a processing flow of the distributed unit selection setting according to the embodiment of the present invention.

The operation management system 100 determines whether or not there are a stop unit and a planned stop unit in each distributed zone (step S401).

By the above processing, the abnormal floor with an abnormality in the power supply device of any of the multiple elevators is excluded from the selection target so that the non-contact power supply type elevator is not assigned as a distributed floor, and the multiple elevators. Of these, the elevators of which one of the units is in maintenance operation, is in an abnormal state, or all of the power supply devices are out of order are excluded from the targets of the units that can be dispatched.

The learning unit 103 determines whether or not there is a unit elevator stopped and a unit elevator scheduled to be stopped in each distributed zone (step S401). In step S401, when there is a unit elevator stopped in each distributed zone and a unit elevator scheduled to be stopped (YES in step S401), the distributed floors in each distributed zone are excluded (step S402). Next, it is determined whether or not the distributed floor exists (step S403), and if the distributed floor already exists (YES in step S403), the stopped unit elevator and the unit elevator scheduled to be stopped are distributed. Exclude from the target unit elevator (step S404). Further, it is determined whether or not there are a plurality of distributed floors (step S405), and if there are already a plurality of distributed floors (YES in step S405), the stopped unit elevator and the unit elevator scheduled to be stopped are determined. Exclude from the unit elevators to be dispersed (step S406). After that, the main process of selecting the distributed unit is executed (step S407).

The vehicle allocation determination unit 102 determines whether or not all the distributed floors have been selected (step S408), and if the selection of the distributed floors has been completed (YES in step S408), ends the process and selects the distributed floors. If is not completed (NO in step S408), the process is repeated until the selection of the distributed floor is completed.

In step S403, if the distributed floor does not exist (NO in step S403), the process ends.

In step S405, when a plurality of distributed floors do not exist (NO in step S405), the main process of selecting the distributed unit is executed (step S407).

Next, the distributed machine selection main process in step S407 will be described. FIG. 12 is a main processing flow for selecting a distributed unit according to an embodiment of the present invention.

The power supply floor setting unit 108 of the operation management system 100 determines whether or not there is a unit elevator (contactless power supply type) that requires power supply as the elevator to be controlled among the plurality of elevators (step S410). When there is a unit elevator that requires power supply (YES in step S410), it is determined whether or not the distributed floor of the unit elevator that requires power supply is the power supply floor (step S411). In step S411, when the distributed floor is the power supply floor (YES in step S411), the vehicle allocation determination unit 102 performs the vehicle allocation determination process from the unit elevator to be distributed (step S412). Basically, if there is a Unit elevator (contactless power supply type) that requires power supply, the distributed floor is treated as a power supply floor. Further, in step S410, when there is no unit elevator that requires power supply (NO in step S410), the vehicle allocation determination unit 102 performs vehicle allocation determination processing from the unit elevator to be distributed (step S412).

In step S411, when the distributed floor is not the power supply floor (NO in step S411), the power supply floor setting unit 108 stops the distributed floor at the unit elevator to be fed according to the pre-registration status from the current position. The predicted battery value at the time is calculated (step S413), and it is determined whether or not the predicted battery value is equal to or greater than the threshold value (step S414).

In step S414, when the power supply floor setting unit 108 determines that the predicted battery value is equal to or higher than the threshold value (YES in step S414), the vehicle allocation determination unit 102 performs vehicle allocation determination processing from the unit elevator to be distributed (step S412). ).

Further, in step S414, when the power supply floor setting unit 108 determines that the predicted battery value is equal to or higher than the threshold value (NO in step S414), the movement time to the nearest power supply floor, the charging time, and the dispersion in the corresponding unit elevator. The time to move to the floor is added to the penalty (step S415).

By the above processing, the vehicle allocation decision unit 102 performs the vehicle allocation decision process, and based on this decision, the vehicle allocation command unit 106 outputs the vehicle allocation command to each unit elevator.

According to this embodiment, it is possible to provide an elevator system and a control method of the elevator system that suppress the influence on the elevator operation due to the failure of the power feeding device.
