Description

  The present invention relates to an elevator group management control device capable of updating a control program by remote operation.

  For example, an elevator installed in a building such as a condominium or an office is operated by an operation that matches the flow of people in the building. However, after the installation of the elevator, if the flow of people to and from each floor changes drastically due to changes in tenants in the building, the building manager may demand improved operations. For example, because the waiting time on the standard floor is long during work hours, you want to change to split operation or add a security setting floor.

  Normally, when there is such a request, the elevator company dispatches maintenance personnel to the site to change the specifications of the elevator. Specifically, a maintenance worker performs an operation of rewriting a control program incorporated in an elevator control device in accordance with a specification change. However, since this operation cannot be performed while the elevator is in operation, it is often performed at night or the like, which places a burden on maintenance personnel.

  Therefore, a method of automatically updating the elevator control program by remote control from the monitoring center is considered. For example, in Patent Document 1, the distribution date and time of the control program is set on the monitoring center side, and when the set distribution date and time is reached, the update control program is distributed to the elevator control device and rewritten. It is disclosed.

Further, in Patent Document 2, when the elevator control device receives an update control program from the monitoring center, it is determined whether or not the elevator is in a quiet state. An update is disclosed.

The means waits for the elevator selected by the update object selection means to enter a non-directional stop state in response to a registered car call, and then uses the update control program to change the elevator control program. It is characterized by updating .

  According to the present invention, since the control program is selectively updated according to the operation status of each elevator, the operation service for the user can be controlled efficiently without interruption even during operation. The program can be updated.

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

(First embodiment)
FIG. 1 is a diagram showing an overall configuration of an elevator group management control system according to a first embodiment of the present invention. In the example of FIG. 1, four elevators (A to D) are installed in a 20-story building.

  The elevator group management control system includes a group management control device 11 for performing group management control of each elevator of cars A to D, and a car control device 12a for individually controlling operation of the elevator cars 13a to 13d. 12d. The group management control device 11 and the car control devices 12a to 12d are composed of computers, and each operate by starting a control program.

  In addition, a hall call button 14 for a user to call an elevator is provided at the hall on each floor. When the hall call is registered by the operation of the hall call button 14, the group management control device 11 selects an optimal car from the elevators of each car according to a predetermined allocation evaluation formula, and assigns the hall to the car. Assign a call to answer.

  The “call to hall” is a call signal registered by operating the hall call button 14 installed on each floor, and includes information on the registered floor and the destination direction. This hall call signal is given to the group management control device 11. On the other hand, the “car call” is a call signal registered by operating a destination floor button (not shown) provided in the car room, and includes information on the destination floor specified by the user. It is. This car call signal is given to the car control device 12 corresponding to the car.

  The group management control device 11 is connected to an external monitoring center 15 via a public line network 16. The monitoring center 15 remotely monitors the operation state of the elevators of each property, and takes measures such as dispatching maintenance personnel to the site when any abnormality is detected. Moreover, the monitoring center 15 is provided with the transmission function of the control program with respect to the elevator of each property. In practice, a monitoring control device (computer) (not shown) is installed in the monitoring center 15, and the monitoring control device performs remote monitoring processing, control program transmission processing, and the like.

  Here, in the present embodiment, the group management control device 11 includes the communication interface unit 21, the program temporary storage unit 22, the update management unit 23, the first program storage unit 24, and the second program storage unit 25. An update target selection unit 26, a program transfer control unit 27, a group management control unit 28, an execution program storage unit 29, and a program switching control unit 30.

  The communication interface unit 21 performs data communication with the monitoring center 15 via the public line network 16. The program temporary storage unit 22 temporarily stores various control programs received from the monitoring center 15.

  The update management unit 23 has a database 23a described later (see FIG. 2), stores update management information (such as type information and update date / time information) related to the control program received from the monitoring center 15, and the type of the control program. In response to this, an update start command is output to the update target selection unit 26 or the program switching control unit 30.

  Here, there are two types of elevator control programs: a “single control program” and a “group management control program”. The “single control program” is a control program for controlling the operation of each elevator. The “group management control program” is a control program for controlling the entire group management system.

  The first program storage unit 24 stores a single control program among various control programs temporarily stored in the program temporary storage unit 22. The second program storage unit 25 stores a group management control program among various control programs temporarily stored in the program temporary storage unit 22.

  The update target selection unit 26 receives the first update start command from the update processing unit 23, and selects a target machine that needs to update the unit control program. The program transfer control unit 27 is used as the first update control unit, and for the car control device 12 of the target machine selected by the update target selection unit 26, the update transfer stored in the first program storage unit 24. The control program is updated by transferring the single control program.

  The group management control unit 28 holds the hall call registered by operating the hall call button 14 on each floor, and assigns elevators to the hall call based on the group management control program stored in the execution program storage unit 29. Control of operation operations such as control, driving at work and driving at lunch.

  The execution program storage unit 29 stores the currently set group management control program for execution. The program switching control unit 30 is used as a second update control unit, receives a second update start command from the update processing unit 23, and transfers the group management control program stored in the execution program storage unit 29 to the second program The control program is updated by rewriting the group management control program stored in the storage unit 25.

  Next, the operation of the first embodiment of the present invention will be described.

  Normally, an elevator operates with an operation that matches the traffic flow and purpose of the building. However, after setting up the elevator, the building manager may request a reduction in waiting time for the hall or a change in the security floor for some reason. For example, since the waiting time on the reference floor in the attendance time zone is long, it is desired to change to attendance time division operation or add the seventh to ninth floors as security floors. In such a case, it is necessary to update the elevator control program in accordance with the specification change.

  The monitoring center 15 creates a control program that satisfies the specifications requested by the building manager and transmits it to the elevator group management control device 11 installed in the building. At this time, update management information is also transmitted in addition to the control program. The update management information includes control program type information, update date information, and the like. The update date and time information is a scheduled date and time when the control program is actually updated in the property, and is arbitrarily designated on the monitoring center 15 side.

  In the group management control device 11, the communication interface unit 21 temporarily stores the control program received from the monitoring center 15 via the communication network such as the public line network 16 in the program temporary storage unit 22 and adds it to the control program. The updated management information (type information, update date / time information, etc.) is given to the update management unit 23. The communication interface unit 21 can also perform data communication with an information terminal device such as a personal computer.

  After completing the reception of the control program, the update management unit 23 determines the type of the control program stored in the program temporary storage unit 22 based on the type information included in the update management information. The control program is transferred to the first program storage unit 24, and if it is a group management control program, the control program is transferred to the second program storage unit 25.

  Further, the update management unit 23 has a database 23a as shown in FIG. The database 23a records control program reception date and time, control program type information, scheduled update date and time, update status, update completion time, and the like.

  The type information includes “single unit” and “group management”, where “single unit” indicates a single unit control program, and “group management” indicates a group management control program.

  The scheduled update date and time has a start time and an end time, and the program update is permitted only when the both set times are satisfied. For example, if the start time is set to 00:00:00 and the end time is set to 01:00:00, the program is updated only between midnight and 1:00:00 Is permitted.

  The update management unit 23 compares the current date and time with the update date and time registered in the database 23a. Then, when the dates and times of the two coincide, that is, when the update date and time are reached, the update management unit 23 determines whether the program transfer control unit 27 is a “single control program” in accordance with the type of the control program. The first update start command is output to the update target selection unit 26, and in the case of the “group management control program”, the second update start command is output to the program switching control unit 30.

  For example, in the example of the database 23a in FIG. 2, when the type information is “single” and the current date is February 23, 2008 00:00:00, the program transfer control unit 27 and the update target selection The first update start command is output to the unit 26.

  Here, the operation when the single control program is updated will be described.

  FIG. 3 is a flowchart showing the update processing operation of the unit control program in the first embodiment of the present invention.

  In the group management control device 11, when the update target selection unit 26 receives the first update start command from the update management unit 23 (Yes in Step A11), the control program is not updated as a predetermined condition, and It is checked whether or not there is an elevator (elevator) that is stopped in a non-directional direction (step A12). The “non-directional stop state” means that the elevator has not registered a call and has stopped in a standby state.

  When there are a plurality of units satisfying the above conditions (Yes in Step A13), the update target selection unit 26 selects any one of them as an update target unit (Step A14). When only one unit satisfies the above conditions (No in step A13), the update target selection unit 26 selects the corresponding unit as the update target unit (step A15). The update target selection unit 26 outputs the information on the update target machine selected in this way to the program transfer control unit 27 (step A16).

  The program transfer control unit 27 transfers the single control program for update stored in the first program storage unit 24 to the car control device 12 corresponding to the car selected by the update target selection unit 26 (step A17). ). As a result, the car control device 12 updates its own control program based on the single control program for update received from the program transfer control unit 27 (step A18).

  Specifically, the control program set in a program memory (not shown) in the car control device 12 is rewritten to the update single control program received from the program transfer control unit 27. At this time, since the elevator is in the non-directional stop state, there is no problem even if the control program is updated during that time. In addition, since the other elevators are in operation, the driving service for the user is not interrupted.

  Then, after the update is completed, the car control device 12 transmits an update completion signal to the update target selection unit 26 and the program transfer control unit 27 (step A19). In response to this, the update target selection unit 26 determines whether or not the program update of all the units has been completed (step A20). When the program update of all the units has not been completed (No in Step A20), the update target selection unit 26 selects the next update target unit (Step A12).

  In this way, until the program update of all the units is completed, the unit that matches the condition is searched one by one and the program is updated. When the program update of all units is completed (Yes in step A21), the program transfer control unit 27 transmits an update completion signal for all units to the update management unit 23. The update management unit 23 updates the contents of the database 23a in response to an update completion signal for all the units (step A21).

  As described above, according to the first embodiment of the present invention, in a state where a plurality of elevators are in operation, elevators that can be updated are selected and sequentially updated. As a result, even during operation, the control program can be updated efficiently without interrupting the operation service for the user, and it is possible to quickly respond to a specification change request from the building administrator. .

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  In the first embodiment, the control program is updated when the elevators of each unit are in the non-directional stop state. However, in the second embodiment, when there is no non-directional stop unit. The control program is updated by forcibly entering a non-directional stop state.

  Since the apparatus configuration is the same as that in FIG. 1 in the first embodiment, the operation of the update process of the single control program will be described here.

  FIG. 4 is a flowchart showing the update processing operation of the unit control program in the second embodiment of the present invention.

  In the group management control device 11, when the update target selection unit 26 receives the first update start command from the update management unit 23 (Yes in Step B <b> 11), the update target selection unit 26 checks whether the control program has not been updated (elevator). (Step B12).

  When there is an unupdated car (Yes in Step B12), the update target selection unit 26 checks whether there is a car that is in a non-directional stopped state among the unupdated car (Step B13). If there is a non-directional stop unit (Yes in Step B13), the update target selection unit 26 selects any one of them as the update target unit, and the group management control unit 28 sets information on the selected update target unit. (Step B14).

  On the other hand, when there is no non-directional stop car (No in Step B13), the update target selection unit 26 sets the car with the smallest registered number of car calls among the elevators of each car currently operating as the car to be updated. The information of the selected update target machine is output to the group management control unit 28 (step B15).

  Here, it is assumed that the group management control unit 28 does not perform an operation command output such as an allocation command or a distributed standby command for the update target machine selected by the update target selection unit 26. Specifically, the update target machine is set as out of group management control (hereinafter referred to as “out of group”) (steps B16 and B17), and thereafter, it is excluded from the newly registered hall call allocation target. To control.

  Thereby, the allocation command for the registered hall call is changed to another car, and the elevator in operation can shift to the non-directional stop state after the response of the registered car call is completed. In other words, by the out-of-group setting, the elevator in operation can be forcibly stopped in a non-directional manner so that it can be updated quickly.

  In step B16, if the elevator that has been in the non-directional stop state from the beginning is set out of the group, the non-directional stop state can be maintained for the elevator even if there is a landing call after that.

  The update target selection unit 26 updates the program transfer control unit 27 after confirming that the update target machine has shifted to the non-directional stop state in response to the already registered car call (Yes in Step B18). The target machine information is output (step B19). The program transfer control unit 27 transfers the single control program for update stored in the first program storage unit 24 to the car control device 12 corresponding to the car selected by the update target selection unit 26 (step B20). ).

  The car control device 12 updates the control program for the elevator based on the single control program for update received from the program transfer control unit 27 (step B21). After completion of the update, the car control device 12 transmits an update completion signal to the update target selection unit 26, the program transfer control unit 27, and the group management control unit 28 (step B22). In response to this, the group management control unit 28 releases the out-of-group setting of the update completion machine (step B23). Further, the update target selection unit 26 selects the next update target car (step B12).

  In this way, when the program update of all units is completed (No in Step B12), the program transfer control unit 27 transmits an update completion signal for all units to the update management unit 23. The update manager 23 updates the contents of the database 23a in response to an update completion signal for all units (step B24).

  Thus, according to the second embodiment of the present invention, as in the first embodiment, the control program is efficiently updated without interrupting the driving service for the user even during driving. can do. Even when there is no updatable elevator, the program update can be started and completed promptly by forcibly setting the non-directional stop state by the out-of-group setting.

(Third embodiment)
Next, a third embodiment of the present invention will be described.

  In the first and second embodiments, the updating method of the unit control program for controlling the operation of each elevator has been described. In the third embodiment, group management control for group management control of the entire elevator is performed. A case where the program is updated will be described.

  Since the apparatus configuration is the same as that in FIG. 1 in the first embodiment, the operation of the group management control program update process will be described here.

  FIG. 5 is a flowchart showing the operation of updating the group management control program in the third embodiment of the present invention.

  In the group management control device 11, when receiving the second update start command from the update management unit 23 (Yes in step C11), the program switching control unit 30 accesses the group management control unit 28 to check whether or not the hall call is registered. Is checked (step C12).

  When the hall call is not registered (Yes in step C12), the program switching control unit 30 sets all the units out of the group through the group management control unit 28 (step C13). As described above, “outside group setting” means setting outside group management control, and the elevator immediately enters a non-directional stop state after the completion of the response of the registered car call.

  On the other hand, when the hall call is registered (No in Step C12), the program switching control unit 30 waits for the registration of the hall call to be lost. This is because if all the cars are set out of the group with the hall call registered, the registered hall call will be canceled and the elevator user will be confused.

  After setting all the units out of the group, the program switching unit 15 rewrites the group management control program for update stored in the second program storage unit 25 to the control program already set in the execution program storage unit 29 ( Step C14). In this case, since all the units are set out of the group, there is no problem even if the group management control program is rewritten.

  After completing the program update, the program switching control unit 30 outputs the update completion signal to the update management unit 23 and the group management control unit 28 (step C15). In response to this, the group management control unit 28 cancels the out-of-group setting for all units (step C16). Further, the update management unit 23 updates the contents of the database 23a (step C17).

  Thus, according to the third embodiment of the present invention, the entire group management system is configured by setting all elevators out of the group after waiting for the registration of the hall call to be lost even during operation. The control program can be updated efficiently.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.

  The update of the above-described single control program or group management control program may not be completed at a preset update date and time depending on the registration status of the hall call and the operation status of the elevator. The fourth embodiment deals with such a case.

  Since the apparatus configuration is the same as that in FIG. 1 in the first embodiment, the operation of the program update process at the end of the update date and time will be described here.

  FIG. 6 is a flowchart showing the operation of the program update process at the end of the update date and time in the fourth embodiment of the present invention.

  When the update end time recorded in the database 23a is reached (Yes in Step D11), the update management unit 23 checks whether there is an incomplete update program (Step D12). If there is an incomplete update program (Yes in Step D12), the update management unit 23 outputs a stop command for all units to the group management control unit 28 via the update target selection unit 26 (Step D13).

  When the group management control unit 28 receives the all-unit suspension command from the update management unit 23, the group management control unit 28 instructs the car control devices 12a to 12d of all the units to stop the operation of each unit. The update target selection unit 26 checks whether or not all the units are in a dormant state. When all units are in a suspended state (Yes in step D14), the update management unit 23 instructs the program transfer control unit 27 or the program switching control unit 30 to update all units according to the type of the control program that has not been updated. Is output.

  That is, if it is a “single control program”, the update management unit 23 outputs an all-machine update command to the program transfer control unit 27. In response to this all-car update command, the program transfer control unit 27 collectively transmits a single control program for updating to the car control devices 12a to 12d of all car numbers. In the car control devices 12a to 12d, program update is executed based on the received single control program for update (step D15). After completion of the update, the car control devices 12a to 12d respectively transmit an update completion signal of each car to the group management control unit 28 (step D16). In response to this, the group management control unit 28 releases the suspension setting for the update completion machine (step D17).

  On the other hand, in the case of a “group management control program”, the update management unit 23 outputs an update command to the program switching control unit 30. In response to this update command, the program switching control unit 30 rewrites the group management control program for update stored in the second program storage unit 25 into the execution program storage unit 29 (step D15). After completing the program update, the program switching control unit 30 outputs an update completion signal to the update target selection unit 26, the program transfer control unit 27, and the group management control unit 28 (step D16). In response to this, the group management control unit 28 cancels the suspension setting for all units (step D17). Further, the update management unit 23 updates the contents of the database 23a (step D18).

  As described above, in the fourth embodiment of the present invention, the unit control program or the group management control program is not easily updated, and when the update end time has elapsed, all the units are forcibly suspended. By executing the program update in the state, it becomes possible to strictly observe the update date of the program.

  Note that the method of the fourth embodiment can also be applied when an abnormality occurs in the elevator control program and the program needs to be changed immediately. In that case, set a short time for the update date and time, and if the update is not completed within that time, it is assumed that an abnormality has occurred, and all units are forcibly put into a suspended state and the program is updated. Just do it.

  Moreover, although each said embodiment demonstrated the case where the control program of an elevator was updated, it is possible similarly when updating the parameter used with the control program.

  In addition, while updating the control program of each unit, for example, a message such as “Currently it cannot be used for the elevator of ** unit. Please wait.” Is displayed on the indicator installed at the landing, The user may be notified by voice. Further, after the control program is updated, the user may be notified of the specific change in the display or voice.

  Specifically, the update management unit 23 refers to the database 23 a to check the program update status of each unit, and sends a notification instruction to the unit being updated via the update target selection unit 26 or the program switching control unit 30. This is given to the control unit 28. In response to this notification command, the group management control unit 28 notifies the landing or the car on each floor that it is being updated. Thereby, even if it is updating, the user can use another elevator without being confused, and can grasp how it was changed after updating.

  In each of the above-described embodiments, the update control program is transmitted from the monitoring center 15. However, the update control program may be transmitted from branch offices located in various locations.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various forms can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be omitted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
