Description

The present invention relates to an elevator group management control system that supports automatic recovery after earthquake detection.

Conventionally, in elevators that support seismic control operation, after performing rescue operation such as stopping the car on the nearest floor when the earthquake detector detects shaking, the elevator is operated until a specialized maintenance person completes the inspection work. Was in a dormant state.

In this elevator, it takes a long time from the occurrence of an earthquake to the resumption of operation, and the services that can be provided to passengers are significantly reduced. Therefore, in recent years, diagnostic operation is automatically performed under predetermined conditions after earthquake control operation. In some cases, the service is prevented from deteriorating by automatically resuming the use of the elevator when no abnormality is detected.

For example, in the abstract of Patent Document 1, as a solution for "the time until automatic recovery can be shortened and the operation can be resumed even if some areas cannot be driven", "by the earthquake detection unit" When an earthquake is detected, the operation control unit individually allocates a floor area for check driving to the elevators of each unit by the area allocation control unit, and the check driving control unit checks and runs each unit. The restoration operation control unit resumes operation in the area where the vehicle can travel based on the driving results of each unit. In this way, by sharing the check operation with each unit, the time until automatic restoration can be shortened. In addition, even if some areas cannot be driven, the operation can be resumed. ", And a method of shortening the time of the diagnostic operation by allocating an area for performing the diagnostic operation to each unit is disclosed.

Japanese Unexamined Patent Publication No. 2008-37630

By the method disclosed in the above patent document, it becomes possible to resume the operation of the elevator early and safely after the control operation during an earthquake. However, with the above method, under the situation where the operating range of each unit is limited immediately after the elevator operation is resumed, if the current floor and the destination floor are separated, the elevator user needs to transfer to the elevator multiple times and move. It is inefficient and inconvenient for users.

The present invention has been made in view of this inconvenience, and an object of the present invention is to move from an arbitrary floor to another floor even when operating in a situation where the operating range of each elevator unit is limited after an earthquake is detected. The purpose of the present invention is to provide an elevator control system capable of suppressing the number of elevator connections when moving.

In order to achieve the above object, the elevator group management control system of the present invention includes a plurality of elevators installed in a building consisting of a plurality of floors, an earthquake detection device for detecting the occurrence of an earthquake, and the earthquake detection. A group management control system for elevators including a group management control device that controls a plurality of elevators based on the output of the device, and the group management control device is a ride of each elevator when an earthquake occurs. The car is stopped on the nearest floor, and after the earthquake stops, the diagnosis area divided by the number of elevators is assigned to each elevator, and after the diagnosis of the assigned diagnosis area is completed, the car of each elevator Sets a reference floor to stop in common, and resumes normal operation of each elevator only on the floor for which diagnosis has been completed and the reference floor , and also for the stop position of the car in the event of an earthquake. The diagnostic area was assigned to each elevator in correspondence with the hierarchical relationship .

According to the present invention, it is possible to suppress the number of elevator connections when moving from an arbitrary floor to another floor even in a situation where the operating range of each elevator unit is limited after an earthquake is detected. ..

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

First, with reference to FIG. 1, an outline of an elevator to which the group management control system of the present invention is applied will be described. The figure shows a group management control system in which three elevators (Units A to C) installed in one building are controlled by a group management control device 2.

As shown here, the elevator of Unit A includes a unit-specific control device 3a, a car 4a, a balance weight 5a, a hoisting machine 6a, and a tail code 7a. By driving the main rope 8a, the hoisting machine 6a raises and lowers the car 4a connected by the main rope 8a and the balance weight 5a in a slidable manner in the hoistway, and controls the control device 3a for each machine. Based on the control signal from the group management control device 2 input via the vehicle, the number of rotations is increased or decreased to raise or lower or stop the car 4a. Further, based on the control signal sent from the unit-specific control device 3a to the car 4a via the tail code 7a, the door of the car 4a is opened / closed, the lighting is turned on, the destination is specified, and the inside of the car in the operation panel 9a is specified. The display, the sound in the car, etc. are controlled. Since these control signals are also transmitted to the group management control unit 22, the group management control unit 22 can sequentially grasp the status of the A unit. The elevators of Units B and C have the same configuration as Unit A. Although a configuration in which three elevators are group-managed is illustrated here, it goes without saying that the present invention described later may be applied to a group management control system in which an arbitrary number of elevators are managed.

The earthquake detection device 1 transmits a signal to the group management control device 2 when the shaking is detected, and is installed in a machine room or the like.

The county management control device 2 is provided with an earthquake detection means 21 and a county management control means 22. The earthquake detection unit 21 detects the occurrence and stop of an earthquake based on the signal received from the earthquake detection device 1. The group management control unit 22 includes a diagnosis area allocation unit 22a, a diagnosis operation control unit 22b, a service operation control unit 22c, and a diagnosis area expansion control unit 22d. Details of each will be described later. It should be noted that some or all of these do not necessarily have to be provided with dedicated hardware, and programs stored in a main storage device such as a semiconductor memory or data stored in an auxiliary storage device such as a hard disk can be stored in a CPU or the like. It may be realized by processing with a computing device.

The diagnosis area allocation unit 22a individually allocates a floor area (hereinafter, referred to as “allocation diagnosis area”) for performing diagnostic operation to each unit of the elevator. The details of the allocation diagnosis area set here will be described later with reference to FIG. 5 and the like.

The diagnostic operation control unit 22b causes each unit to perform a diagnostic operation according to the allocation of the diagnostic area allocation unit 22a. The diagnostic operation is an operation for diagnosing both whether the car of each unit can pass through the floor area and whether the landing door of the floor of each unit opens and closes normally.

The service operation control unit 22c causes each unit to resume operation in the travelable area based on the result of the diagnostic operation of each unit.

The diagnosis area expansion control unit 22d causes each unit that has resumed operation to perform a diagnosis operation outside the initial assigned diagnosis area under predetermined conditions.

The unit-specific control devices 3a, 3b, and 3c controlled by the group management control unit 22 are the unit control units 31a, 31b, 31c, the position detection units 32a, 32b, 32c, and the user presence / absence determination units 33a, 33b, 33c, respectively. It is provided with use section display units 34a, 34b, 34c. It should be noted that some or all of these do not necessarily have to be provided with dedicated hardware, and programs stored in a main storage device such as a semiconductor memory or data stored in an auxiliary storage device such as a hard disk can be stored in a CPU or the like. It may be realized by processing with a computing device.

The unit control units 31a, 31b, 31c control the hoisting machines 6a, 6b, 6c, etc. of each unit according to the signal sent from the group management control unit 22.

The position detection units 32a, 32b, and 32c detect the floor on which the car is located for each unit and transmit data to the group management control unit 22.

The user presence / absence determination units 33a, 33b, 33c receive information from the load sensors 10a, 10b, 10c and the landing buttons 12a, 12b, 12c for each unit, determine the presence / absence of a user for each unit, and the determination result. Is transmitted to the group management control unit 22.

Based on the information from the group management control unit 22, the use section display units 34a, 34b, and 34c display the usable floors of the unit, such as the indicators of the operation panels 9a, 9b, and 9c, and the landing indicators 13a, 13b. , 13c is used to control the display.

An example of specific control in the group management control system of the present embodiment having the above configuration will be described with reference to the flowcharts of FIGS. 2 to 4 and the schematic views of FIGS. 5 to 9.

FIG. 2 is a flowchart for explaining the processing procedure of this embodiment. When an earthquake occurs and the earthquake detection device 1 operates (S1), after detecting the earthquake, the group management control device 2 is the most of the car 4a, 4b, 4c with respect to the control devices 3a, 3b, and 3c for each unit. Order to move to the nearest floor and stop at the nearest floor (S2).

When the cars 4a, 4b, and 4c stop at the nearest floor, the diagnosis area allocation unit 22a allocates the diagnosis area to each unit (S3). In this step, the diagnostic area is assigned to each unit as follows. That is, first, the number of elevator units is acquired (S31), and the stop positions of each unit are acquired from the position detection units 32a, 32b, and 32c (S32). After that, a plurality of allocated diagnostic areas are created by equally dividing all floors by the number of units (S33), and the diagnostic areas are allocated according to the positional relationship between the stop position of each unit and the equally divided allocated diagnostic areas (S33). S34).

For example, as shown in FIG. 5, when three elevators are installed in a 30-story building, in step S33 described above, the 30th floor is divided into three equal parts, and the lower floors (1F to 10F) and the middle floor (1F to 10F). It is divided into three assigned diagnosis areas (11F to 20F) and higher floors (21F to 30F). If the stop positions of the car are dispersed in each allocation diagnosis area such as Unit A on the 10th floor, Unit B on the 15th floor, and Unit C on the 25th floor, Unit A is on the lower floor including 10F, and Unit B. The middle floor including the 15th floor is allocated to Unit C, and the upper floor including the 25th floor is allocated to Unit C as the allocation diagnosis area (S34). Although FIG. 5 shows an example in which all floors are equally divided by the number of units, the size of each allocated diagnosis area may be different, and as shown in FIG. 6, each allocated diagnosis area partially overlaps. You may.

In step S4 of FIG. 2, the diagnostic operation control unit 22b issues a command to the unit-specific control devices 3a, 3b, and 3c, and each unit performs a diagnostic operation in the allocated diagnostic area assigned by the diagnostic area allocation unit 22a (S4). ). Then, it is diagnosed whether there is a non-driving area in the allocated diagnosis area (S5), and if a non-driving area is found in the allocated diagnosis area of a certain unit, the nearest diagnosis area is assigned to diagnose the non-driving area. The other unit will be in charge (S6).

When the diagnostic operation for all floors in the allocated diagnostic area is completed (Yes in S7), the service operation control unit 22c permits the restart of the normal operation in the diagnosed area (S8). At this time, the use section display units 34a, 34b, 34c display the usable areas on which the normal operation has been resumed on the indicators of the operation panels 9a, 9b, 9c and the landing indicators 13a, 13b, 13c.

After resuming normal operation limited to the area, when the user presence / absence determination units 33a, 33b, 33c of each unit detect that there are no users (S10, S11), the diagnosis area expansion control unit 22d sets the floor where the diagnosis is not completed. The diagnosis is executed by setting the enlarged diagnosis area (S12), and the number of runnable floors is gradually increased (S8).

Here, the details of the method for determining the presence or absence of a user in step S10 will be described with reference to FIG. The user presence / absence determination units 33a, 33b, 33c of each unit detect the absence of an elevator user under two conditions. One is when there is no load in the car based on the information of the load sensors 10a, 10b and 10c (S101), and the other is when the landing buttons 12a, 12b and 12c are not pressed for a predetermined time or more (S102). If both of these are true, it is determined that there is no user (S103). On the contrary, if neither of them is applicable, it is assumed that there is a user (S104).

Next, the details of the diagnosis area expansion control in step S12 will be described with reference to FIG. In step S12, it is first determined whether the reference floor has been determined (S121). When the reference floor is undecided (No in S121), the diagnosis area expansion control unit 22d tentatively determines the reference floor and allocates it to the diagnosis area of each unit (S122). Here, the reference floor is a floor on which a plurality of cars stop in common, and if a transfer is made on this reference floor, it is possible to move from any floor to another floor with the minimum number of connections. Will be. Normally, it is desirable to set the reference floor to the first floor, but the floor with the most users may be set to the reference floor.

On the other hand, if the reference floor has already been determined (Yes in S121), the stop position when the user is absent is acquired from the position detection units 32a, 32b, 32c of each unit (S123), and the nearest diagnostic operation is not performed. The implementation floor is detected (S124), and the floor is assigned to the diagnostic area of each unit (S125).

When the diagnostic area is added in step S122 or step S125, each unit performs a diagnostic operation on the newly assigned area (S126). Then, if there is no abnormality in the diagnosis operation result of the new diagnosis area (S127), the floor is added to the service operation area (S8). When there is an abnormality in the diagnosis result (S127), it is detected whether the driving is in the up / down direction or the floor where the abnormality occurred (S128). If the direction is upward, the floors above the floor with abnormal diagnostic operation are excluded from the floors where the diagnostic operation has not been performed, and the diagnostic area is not expanded to the floors after that (S1210). Similarly, if the direction is downward, the floors below the floor with abnormal diagnostic operation are excluded from the floors on which diagnostic operation has not been performed, and the diagnostic area is not expanded to the floors after that (S1211). As shown in FIG. 2, the diagnosis area expansion control in step S12 is repeatedly executed until there are no floors on which the diagnosis operation has not been performed (S9).

Next, the process in step S12 will be specifically described with reference to FIGS. 7 to 9. Here, it is assumed that the diagnosis in the assigned diagnosis area initially assigned to each unit has been completed.

FIG. 7 is a diagram illustrating step S122 of FIG. As shown here, when the reference floor is undecided (No in S121), the diagnosis area expansion control unit 22d tentatively determines a specific floor (for example, the first floor) as the reference floor (S122), and sets each unit. A diagnostic operation is performed (S126). If there is no abnormality in the diagnosis result, the tentatively determined floor is determined as the reference floor. Therefore, as shown in FIG. 7, each unit can use the reference floor in addition to the initial assigned diagnosis area.

As a result, for example, if you want to move from the 1st floor to the 30th floor, before setting the standard floor, move from the 1st floor to the 10th floor with Unit A, move from the 10th floor to the 11th floor with the stairs, and move from the 11th floor with Unit B. I had to move to the 20th floor, move from the 20th floor to the 21st floor by stairs, and move from the 21st floor to the 30th floor with Unit C, but after making the 1st floor the standard floor, Unit C is 1 You will be able to move from the floor to the 30th floor. That is, the number of elevator connections is reduced from 2 to 0, and the number of stairs is reduced from 2 to 0.

Also, if you want to move from the 5th floor to the 25th floor, before setting the standard floor, move from the 5th floor to the 10th floor with Unit A, move from the 10th floor to the 11th floor with the stairs, and move from the 11th floor to the 20th floor with Unit B. I had to move to the floor, move from the 20th floor to the 21st floor by stairs, and move from the 21st floor to the 25th floor by Unit C, but after making the 1st floor the standard floor, the 5th floor by Unit A After moving to the 1st floor, you will be able to move from the 1st floor to the 25th floor with Unit C. That is, the number of elevator connections is reduced from 2 to 1, and the number of stairs is reduced from 2 to 0.

On the other hand, when the reference floor has been determined (Yes in S121), the diagnostic operation is performed from the stop position of the elevator when the user is absent to the nearest floor where the diagnostic operation has not been performed. For example, when each unit is stopped at the position shown in FIG. 8, Unit A performs diagnostic operation with the 11th floor, which is the nearest floor where diagnostic operation has not been performed, as the enlarged diagnostic area, and Unit B performs diagnostic operation with the 21st floor as the enlarged diagnostic area. The diagnostic operation is performed as, and Unit C performs the diagnostic operation with the 19th floor as the expanded diagnostic area. Similarly, when each unit is stopped at the position shown in FIG. 9, Unit A performs diagnostic operation with the 11th floor as the enlarged diagnostic area, Unit B performs diagnostic operation with the 9th floor as the enlarged diagnostic area, and Unit C. Performs diagnostic operation with the 2nd floor as the expanded diagnostic area.

According to the configuration of the first embodiment described above, since each unit has set a reference floor in which a plurality of units are commonly stopped after the diagnosis of the initially assigned allocation diagnosis area is completed, the user is arbitrary. It is possible to minimize the number of elevator connections when moving from one floor to another.

Next, the elevator control system of the second embodiment will be described with reference to FIGS. 10 and 11. It should be noted that the common points with the first embodiment will be omitted.

In FIG. 5 of the first embodiment, after the earthquake is detected, each unit is dispersed and stopped on the lower floors (1st to 10th floors), the middle floors (11th to 20th floors), and the upper floors (21st to 30th floors), respectively. Of the three divided diagnostic areas, the lower floor area is the lower floor stopped Unit A, the middle floor area is the middle floor stopped Unit B, and the upper floor area is the higher floor stopped Unit C. Assigned to.

However, when each unit stops on the adjacent floor, the allocation method of the first embodiment cannot be applied. Therefore, in this embodiment, a method of allocating a diagnostic area to each unit will be described by taking as an example a situation in which all units A to C are stopped on a higher floor.

FIG. 10 is a diagram for explaining the method of allocating the diagnostic area adopted in the elevator control system of this embodiment. After the earthquake is detected, Unit A stops on the 26th floor, Unit B stops on the 22nd floor, and C. It shows the situation where Unit stopped on the 28th floor.

Here, in FIG. 10, the allocation diagnosis area divided into three is assigned in correspondence with the vertical relationship of the stop floors of each unit. That is, the lower floor area is assigned to Unit B stopped on the lowest 22nd floor, the middle floor area is assigned to Unit A stopped on the 26th floor above it, and the higher floor area is assigned to Unit C stopped on the highest 28th floor. It was. With such an allocation method, even when a plurality of units stop on adjacent floors, the diagnosis area can be allocated in a combination that minimizes the movement time from the stop location to the allocation diagnosis area.

FIG. 11 is a diagram for explaining an alternative method of allocating the diagnostic area adopted in the elevator control system of this embodiment. Similar to FIG. 10, Unit A stops on the 26th floor after the earthquake is detected, and Unit B is displayed. Has stopped on the 22nd floor, and Unit C has stopped on the 28th floor.

Here, in FIG. 11, the allocation diagnosis area divided into three is allocated to the default unit regardless of the stop floor of each unit. That is, the lower floor area was assigned to the default Unit A, the middle floor area was assigned to the default Unit B, and the upper floor area was assigned to the default Unit C. With such an allocation method, even if multiple units stop on the adjacent floor, the allocation of the diagnosis area to each unit can be decided promptly, so the diagnosis in each allocation diagnosis area should be started early. Can be done.

In addition, in FIGS. 10 and 11, the size of the assigned diagnosis area of each unit is made equal, but the size may be different in consideration of the performance of each unit. Further, in FIGS. 10 and 11, the allocation diagnosis area of each unit is set exclusively, but it may be set in duplicate. Further, in FIGS. 10 and 11, although the allocated diagnosis area of each unit is composed of continuous floors, it may be configured to include dispersed floors.
