Description

  The present invention relates to an elevator group management control device and an elevator group management control method, and is suitable for application to an elevator group management control device and an elevator group management control method for performing destination floor registration at an elevator hall. is there.

  Conventionally, group management control for efficiently operating a plurality of elevators has been performed. In elevator group management control, for example, an optimal elevator is selected from a plurality of elevators for a car call of a user, or an elevator that performs maintenance or the like is separated from a plurality of elevators and operated. It has been broken.

  In Patent Document 1, an independent operation switch is operated in order to operate a specific elevator independently from a plurality of elevators under group management control, and a destination call is given to the elevator corresponding to the operated operation means by the determining means. If assigned, it is disclosed that the elevator responds to the destination call before making the elevator independent of the control of the determining means.

  In Patent Document 2, registration of a new hall call is prohibited on the condition that the maintenance operation selection signal is received, and the operation control means sequentially responds to the registered hall call and car call. It is disclosed that after the registration of the hall call and the car call is canceled, the operation mode of the operation control means is switched to the maintenance operation mode.

  In general elevator group management control, the registered call and the provisional registration call are canceled when switching is performed by a maintenance switch provided in the car. Therefore, as described in Patent Document 1 and Patent Document 2, new calls are prohibited from being accepted at the time of maintenance operation switching so as not to impair the convenience of the user at the time of switching during maintenance operation, while responding to registered calls. After completing the service for all calls, the operation is switched.

  By the way, in recent years, there is a group management system using a landing destination floor input unit capable of registering a destination floor from the landing. As described above, in Patent Documents 1 and 2, both services for all calls while responding to registered calls. Upon completion, new calls are not accepted. For example, a destination call to the same floor may be created after switching to maintenance operation in a state where a destination call from a landing is already registered. In this case, since the elevator switched to the maintenance operation prohibits acceptance of a new call, the other elevators are stopped instead of the elevator. That is, after the elevator maintenance operation, a plurality of elevators may stop for the same destination floor, and there is a problem that the operation efficiency of the elevator is lowered.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an elevator group management control device and an elevator that can manage an elevator group that is group-controlled under priority on the use state of the elevator when performing maintenance operation of the designated elevator. We are going to propose a group management control method.

In order to solve such a problem, in the present invention, a unit control system that controls boarding / exiting and opening / closing of doors in a single unit of a plurality of elevator units, and a plurality of unit control systems are linked to manage operation of a plurality of units. An operation management control unit for performing a maintenance operation switching command to an arbitrary unit of a plurality of elevators, and switching the maintenance operation to a target vehicle for the maintenance operation switching command. It is determined whether or not the restriction that restricts the traffic is resolved, and when the restriction is resolved, a maintenance operation command is given to the arbitrary unit, and the current traffic situation is congested and the restriction matters characterized that you determined not eliminated, the group management control device of the elevator is provided.

  According to such a configuration, when performing maintenance operation of the elevator under the group management control, the elevator specified in the landing destination floor input unit for performing call registration installed in the landing area, giving priority to the use state of the elevator. Perform maintenance operation. As a result, it is possible to specify the number of units that perform maintenance operation from the landing destination floor input unit, and not to give priority to the maintenance operation command, but to improve the convenience of the user by giving priority to the use state of the elevator apparatus. it can.

  According to the present invention, when performing maintenance operation of an elevator designated from a landing destination floor input unit for performing call registration installed at a landing, an elevator group that is subjected to group management control giving priority to the use state of the elevator Can be managed and user convenience can be improved.

1 is a block diagram of an elevator group management control system according to an embodiment of the present invention. FIG. It is a block diagram which shows the specific structure of the maintenance function restriction | limiting process part concerning the embodiment. It is a flowchart which shows the detail of the maintenance function control process concerning the embodiment. It is a flowchart which shows the detail of the maintenance function control process concerning the embodiment.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

(1) Configuration of Group Management Control System FIG. 1 is a block diagram of an elevator group management control system according to the present embodiment.

  As shown in FIG. 1, a landing destination floor input unit 1 provided at a landing of an elevator includes a destination floor input unit 2 that registers a destination floor by an operation from the landing, and a maintenance target unit for performing maintenance operation. The maintenance operation command input unit 3 for designating and the notification unit 4 for notifying the operator of the results of these inputs.

  The destination floor input unit 2 includes, for example, a numeric keypad, a destination button, and a card reader, and is an input unit for a user to register a target floor in the elevator from the landing.

  The maintenance operation command input unit 3 uses the input unit of the destination floor input unit 2 described above, and receives a card for maintenance operation by a numeric keypad device of the destination floor input unit 2, a cryptographic operation using a destination button, or a card reader. It is an input unit for inputting a maintenance operation command by reading.

  For example, when a maintenance operation command is input by a cryptographic operation, the maintenance operation command is output by performing an input operation different from that of a normal user by using a numeric keypad. Thereby, it is possible to separate normal use and use at the time of maintenance with one input unit without installing a new independent button or the like for the maintenance operation command. Actually, for example, when a maintenance operation command is input, an input method such as pressing a “0” button three times within 2 seconds and then inputting a 4-digit password can be used.

  In addition, it is good also as a structure which installs the application which only a maintenance worker can acquire in the portable terminal which an individual owns, and inputs a maintenance driving | operation instruction | command by the said application.

  The landing destination floor input unit 1 is connected to the group management control system 7 via the input / output control system 5 and the switching means 6. Normally, the switching means 6 connects the input / output control system 5 and the group management control system 7, but if any failure occurs, the connection is switched and the input / output control system 5 and each group The unit control systems 8A to 8N can be connected.

  As described above, the destination floor information input from the landing destination floor input unit 1 is transmitted to the group management control system 7 via the input / output control system 5. In addition to the destination floor information, the landing destination floor input unit 1 has information on the installation floor of the landing destination floor input unit 1 and a wheelchair button, a dedicated operation button, etc. installed in the landing destination floor input unit 1 Send special call information. Thereby, the group management control system 7 can acquire the information for performing the optimal number machine selection.

  Each elevator car under group management control controls raising and lowering of the cars 10A to 10N via hoisting machines 9A to 9N controlled by the respective car control systems 8A to 8N.

  The learning system 11 in the group management control system 7 can recognize the current traffic situation from the daily operation state based on the accumulated information. The learning system 11 in the group management control system 7 learns the traffic situation based on the car usage information and destination floor information such as the car position and the number of passengers, and what kind of driving program is suitable at that time. Judging. For this reason, it is possible to identify whether the number of passengers getting on and off by floor indicating the flow of people in the building belongs to the feature mode indicating the typical traffic situation in the building from the online input information.

  Here, the feature mode indicates the situation of the traffic situation divided into a certain number by the downlink and uplink traffic information. Usually, in the case of an office building, the traffic situation with a small number of passengers both up and down is called quiet, the traffic situation with many people going up and down is called up-peak, and the traffic situation with many people getting on and off is called down-peak. The feature mode has different features depending on the properties of the building, and new features may be extracted from the collected traffic conditions. When a new feature is extracted, the learning system 11 generates and registers it as a feature mode unique to the building. Further, the learning system 11 learns the tendency of other feature mode changes.

  The intelligent system 12 generates a new feature mode unique to the building separately from the feature mode indicating a typical traffic situation in the building, and controls each elevator using the generated feature mode.

  Further, the operation management control unit 13 includes a destination floor registration processing unit 14, a maintenance operation recognition processing unit 15, a maintenance function restriction processing unit 16, and a maintenance operation command processing unit 17.

  The destination floor registration processing unit 14 is based on the operation information of the unit managed by the group management control system 7 from the destination floor information, the installation floor information, and the special call information input from the landing destination floor input unit 1. In accordance with the traffic flow that changes from moment to moment, processing related to call registration is performed to select the optimal unit considering operation efficiency. Here, the operation information of the unit whose operation is managed by the group management control system 7 includes position information in the elevator, movement direction information of the elevator, information on the number of people in the car, and the like.

  The maintenance operation recognition processing unit 15 receives a signal from the maintenance operation command input unit 3 that designates a car that performs the maintenance operation from the landing destination floor input unit 1, and determines whether or not an appropriate maintenance operation can be performed. The maintenance function restriction processing unit 16 stores in advance restriction items when a maintenance operation command is given to a target vehicle, and determines whether these restriction items have been eliminated when performing maintenance operation. The maintenance operation command processing unit 17 gives a maintenance operation command to the relevant car when the restriction items in the maintenance function restriction processing unit 16 are eliminated. Details of the restrictions will be described later.

(2) Functional Configuration of Group Management Control System FIG. 2 is a block diagram showing a specific configuration of the maintenance function restriction processing unit 16 described above. As shown in FIG. 2, the maintenance function restriction processing unit 16 includes a time zone determination unit 18, a service end determination unit 19, a maintenance allocation mode processing unit 20, and a maintenance impossibility notification unit 21.

  The time zone determination unit 18 determines that there is no limit on the time zone as a restriction item. Specifically, the time zone determination unit determines whether the traffic flow is in a normal state or a quiet state, not in a work time zone or a crowded time zone. The service end determination unit 19 determines whether the service for the registered call in the unit that is the target of the maintenance operation as a restriction item is ended.

  The maintenance allocation mode processing unit 20 executes the maintenance allocation mode processing when the service end determination unit 19 determines that the service has not ended. Specifically, the maintenance allocation mode process is a process for reconsidering whether maintenance operation can be performed after giving an opportunity to end the service efficiently when the service has not ended.

  By executing the maintenance assignment mode process, when the service end determination unit 10 determines that the service has not ended, the maintenance operation command can be temporarily suspended. In other words, when a maintenance operation command is not given, it is possible to determine whether maintenance operation can be performed again after processing a service that has not ended, instead of determining that maintenance operation cannot be performed immediately. Yes.

  The maintenance impossibility notifying unit 21 is a time zone in which maintenance operation cannot be performed by the time zone determining unit 18, a case where the service end determining unit 19 determines that the service has not ended, or a maintenance allocation mode processing unit. When it is determined that the maintenance operation cannot be performed by the user 20, the user who has input the maintenance operation instruction that the maintenance operation is not possible immediately, or that the maintenance is switched after the service for the already registered ( Notify maintenance personnel).

(3) Details of Group Management Control Processing Next, details of the maintenance function control processing in the maintenance function restriction processing unit 16 will be described with reference to FIGS. 3 and 4. The maintenance function control process described below is a process executed when a maintenance operation command is input in the elevator group management control process. Since the elevator group management control process is the same as the conventional process, a detailed description thereof will be omitted.

  As shown in FIG. 3, first, the maintenance function restriction processing unit 16 determines whether or not a maintenance operation command has been input by a maintenance worker (S1). The maintenance function restriction processing unit 16 monitors a maintenance operation command from the maintenance operation recognition processing unit 15 and outputs a maintenance operation command from the maintenance operation recognition processing unit 15 when a maintenance operation command is input by a maintenance staff. To do. As described above, the maintenance operation command input is performed by performing a cryptographic operation of the destination floor input unit 2 of the landing destination floor input unit 1 (pressing the “0” button on the numeric keypad three times within 2 seconds and then entering a 4-digit password) Or by reading the ID card information for maintenance operation commands.

  If it is determined in step S1 that a maintenance operation command has been input, the time zone determination unit 18 of the maintenance function restriction processing unit 16 determines whether the restriction items have been eliminated (S2). Here, the restriction item means, for example, a case where the time zone in which the maintenance operation command is input is a time zone for work or a busy hour. The time zone determination unit 18 determines that the restriction has not been resolved when the time zone in which the maintenance operation command is input is a time zone, or a busy time zone, and the time zone in which the maintenance operation command is input. If is in a normal state or a quiet state, it is determined that the restriction has been removed.

  In step S2, when it is determined that the time zone in which the maintenance operation command is input corresponds to the restriction item, that is, when it is a time zone or a busy hour zone, and the traffic flow is not in a normal state or a quiet state, Since the maintenance operation cannot be registered, the maintenance impossibility notification unit 21 of the maintenance function restriction processing unit 16 outputs a maintenance addition notification to the notification unit 4 of the landing destination floor input unit 1 (S6).

  The maintenance staff usually predicts or investigates the usage pattern of the elevator installed in the building, and goes to the building to perform maintenance operation outside the limited time zone. However, if the traffic flow of the building is not as predicted, the maintenance operation is not registered in step S2. For this reason, the maintenance operation of the elevator is not given the highest priority, but the use form of the elevator apparatus in the building is given priority, and it is possible to prevent the convenience of the user from being impaired by the maintenance operation.

  On the other hand, when it is determined in step S2 that the normal state or the quiet state in which the restrictions are eliminated, the service end determination unit 19 determines whether all the registered calls of the relevant unit are serviced. (S3).

  If it is determined in step S3 that all registered call services have been completed, a maintenance operation command is given to the car through the maintenance operation command processing unit 17 (S4). It moves to the floor to which the maintenance operation command is input, and switches to maintenance operation when it arrives at the floor. Further, at that time, the notification unit 4 of the landing destination floor input unit 1 notifies the switching guidance such as “** Unit has been switched to maintenance operation”. As other notification methods, the above guidance is output by voice, the guidance is displayed on the display installed in the car, or the lantern installed at the landing is flashed separately from the arrival guidance (upward For example, a reservation light for the first time, a blinking reservation light for the lower direction, etc.).

  On the other hand, if it is determined in step S3 that all services have not yet been completed for the registered call, the maintenance allocation mode process of the relevant unit is performed in the group management control system 7. The process proceeds to the unit 20 (S5).

  Next, the details of the maintenance assignment mode process performed by the maintenance assignment mode processing unit 20 in step S5 will be described with reference to FIG.

  The maintenance allocation mode processing unit 20 of the maintenance function restriction processing unit 16 determines whether or not there is a machine that is transitioning to the maintenance allocation mode (S6). If there is no unit that is shifting to the maintenance assignment mode in step S6, the maintenance assignment mode processing unit 20 ends the process.

  On the other hand, if there is a car that is shifting to the maintenance assignment mode in step S6, the maintenance assignment mode processing unit 20 determines whether a new car call by the user has been input (S7). If it is determined in step S7 that a new call has not been input, the processing of step S11 described later is executed by continuously setting the relevant unit as the maintenance allocation mode.

  On the other hand, if it is determined in step S7 that a new call has been input, the maintenance allocation mode processing unit 20 determines whether the predicted number of passengers in the relevant unit is full (S8).

  On the other hand, if it is determined in step S8 that the predicted number of passengers in the relevant unit is not full, the departure floor, destination floor and directionality of the new call are the same as the registered call of the unit in maintenance allocation mode. It is determined whether it coincides with the stop floor and direction (S9).

  If it is determined in step S9 that they match, the maintenance assignment mode processing unit 20 assigns a new call to the relevant car (S10).

  On the other hand, if it is determined in step S8 that the predicted number of passengers in the relevant unit is full, and if it is determined in step S9 that they do not match, the maintenance allocation mode processing unit 20 responds to the new call. Then, the relevant machine is excluded from the assignment (S13).

  In this way, all the services of registered calls have not been completed by the maintenance allocation mode processing unit 20, and the machine that has been shifted to the maintenance allocation mode can efficiently service the remaining registered calls. To complete all registered calls. However, in a situation where all the services cannot be completed, the car is excluded from the car call assignment during the maintenance assignment mode so that a new call is not assigned to the car.

  And the maintenance function restriction | limiting process part 16 determines whether all the registered calls with respect to the said number machine are serviced (S11). If it is determined in step S11 that all services have been completed, the maintenance allocation mode processing unit 20 gives a maintenance operation command to the relevant machine via the maintenance operation command processing unit 17.

  On the other hand, if it is determined in step S11 that all services have not been completed, the maintenance allocation mode processing unit 20 continues to set the relevant unit to the maintenance allocation mode.

  In Step S11, the relevant machine that has received the maintenance operation command moves to the floor to which the maintenance operation command is input, and switches to maintenance operation when it reaches the floor. Further, at that time, the notification unit 4 of the landing destination floor input unit 1 notifies the switching guidance such as “** Unit has been switched to maintenance operation”. As other notification methods, the above guidance is output by voice, the guidance is displayed on the display installed in the car, or the lantern installed at the landing is flashed separately from the arrival guidance (upward For example, a reservation light for the first time, a blinking reservation light for the lower direction, etc.).

(4) Effects of the present embodiment As described above, according to the present embodiment, from the landing destination floor input unit 1 for performing call registration installed at the landing without providing a maintenance switch in the car. It is possible to specify the unit that performs maintenance operation. In addition, the maintenance function control process by the maintenance function restriction processing unit 16 can prioritize the maintenance operation command, but can prioritize the use state of the elevator apparatus, so that convenience for the user can be improved.

  Moreover, if the time zone and the registered call are taken into consideration as the restriction items by the maintenance function restriction processing unit 16, the convenience of the user of the elevator device can be further prioritized and the elevator device can be operated. In addition, when there is a registered call by the maintenance assignment mode processing by the maintenance assignment mode processing unit 20, the maintenance operation instruction is not immediately given, but the maintenance operation instruction is put on hold and the service is efficiently performed. It is possible to reconsider whether maintenance operation is possible. As a result, it is possible to perform the maintenance operation with some flexibility.

(5) Other Embodiments In the present embodiment, the maintenance allocation mode processing unit 20 in step S9, the starting floor and destination floor of the new call, the stop floor of the unit that performs the maintenance operation, and Judgment is made based on the directionality, and it is determined whether or not allocation is possible to prevent an increase in the stop floor of the relevant unit. However, the present invention is not limited to this. For example, in step S9, a method of permitting call registration between the current floor and the final destination floor of the relevant unit, or a method of permitting preliminary registration for a certain period after a maintenance operation is input may be used.

  Also, in this embodiment, registration of a new car call is permitted when the direction of the new call and the direction of the final car call of the unit that performs maintenance operation match, but this is limited to this example. Not. For example, even if the direction of the last car call of the unit that performs maintenance operation is different from the direction of the new landing call, if the stop floors of the two coincide, the new car call registration may be permitted. Good.

  In the above-described embodiment, the above-described restriction condition is added by the maintenance function restriction processing unit 16, but the present invention is not limited to this restriction condition. For example, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to the one having all the configurations described.
