Description

  Embodiments described herein relate generally to an elevator control device and an elevator system.

  Conventionally, it is desirable to perform maintenance inspection work periodically after an elevator is installed in a building or the like. When performing maintenance and inspection work, the worker (maintenance staff) checks the operation of each device and performs maintenance on each part by stopping normal elevator operation, for example, high-speed elevator operation and low-speed operation. We are carrying out. Therefore, the user cannot basically use the elevator during the maintenance inspection work. In this case, the user may wait until the maintenance / inspection work is completed and the normal operation is resumed, or the user may use another movement route such as stairs. However, it may not be understood how long it will take for the maintenance and inspection work to end, which may confuse the user. In addition, there are users who are difficult to use stairs, such as wheelchair users and elderly people. In view of this, there have been proposed an elevator equipped with a system capable of talking with an operator during maintenance inspection work and an elevator equipped with a system capable of displaying the end time of the maintenance inspection work.

  However, in the prior art, it is possible to notify the guide of the time until the elevator can be used by displaying the end time of the maintenance and inspection work, etc., but the elevator can actually be used. This is after the maintenance and inspection work is completed, and will wait until then. In addition, when the user and the worker can talk and only switch to the inspection mode and have not started the actual work, the worker returns to the normal operation mode from the inspection mode and uses the elevator. You can also However, when the maintenance / inspection work is resumed, it is necessary to switch to the inspection mode again, and the efficiency of the maintenance / inspection work is reduced. Therefore, if the elevator can be operated even during inspection work, the elevator can be temporarily operated, and if an elevator control device that returns to the inspection mode after use is obtained, the convenience of the user can be obtained. This improves the efficiency of maintenance and inspection work and is meaningful.

  The elevator control device of the embodiment includes, for example, a control unit, a determination unit, and a mode switching unit. The control unit includes a normal operation mode for normal operation of the elevator, an inspection mode in which the normal operation mode is stopped for inspection of the elevator, and a mode for placing a specific user on the car during the execution of the inspection mode. Then, after moving the specific user to the destination floor, one of the temporary operation mode for returning to the inspection mode when a predetermined condition is satisfied is executed. The determination unit determines whether or not the specific user exists on a reference floor that allows the specific user to board during execution of the inspection mode. The mode switching unit outputs a switching command for switching the control state of the control unit from the inspection mode to the temporary operation mode when a specific user exists on the reference floor and the call registration of the car is received on the reference floor.

  Hereinafter, an elevator control device and an elevator system according to embodiments will be described in detail with reference to the drawings. The constituent elements in this embodiment include those that can be easily replaced by those skilled in the art or that are substantially the same, and the present invention is not limited to the following embodiments.

  FIG. 1 is a schematic diagram illustrating a configuration of an elevator system (elevator 10) to which the elevator control device of the embodiment can be applied. The elevator 10 moves up and down a hoistway 12 installed in a building (a building, a condominium, etc.) and moves between landings 18 provided on each floor 16. The elevator 10 is configured as a so-called elevator elevator in which a car 14 and a counterweight 20 are connected by a main rope 22. In this embodiment, the hoistway 12 shows the example installed in the building of "n" stories as an example. Each floor 16 indicates the first to nth floors by reference numerals 16 (1),..., 16 (n-1), 16 (n). In the present embodiment, for example, the first floor 16 (1) is an entrance floor and may be referred to as a “reference floor” that means a floor on the flow line that enters from the outside of the building and enters the elevator 10. In addition, the “reference floor” may mean a floor that allows a “specific user” described later to enter the car 14.

  The hoistway 12 is provided along the vertical direction of the building including the elevator 10, and is provided across a plurality of floors in the building so that the vertical direction is the elevating direction. In addition, a machine room 32 for installing a hoisting machine 24 (including a motor 26 and a main sheave 28) for moving the car 14 up and down, a deflecting sheave 30 and the like is provided on the upper side of the hoistway 12 in the up-and-down direction. . The hoistway 12 is provided with a guide rail (not shown) extending in the elevating direction that serves as a guide when the car 14 moves up and down.

  In the position corresponding to the landing 18 on each floor 16 of the hoistway 12, for example, a rectangular landing opening 12a is provided, and when the car 14 moves to the landing 18 on each floor 16 and stops, the car door of the car 14 34 coincides with the position of the landing opening 12a. Each platform 18 is provided with a platform door 36 that can be opened and closed so as to block the platform opening 12a. The landing door 36 is normally in a closed state, and its operation to the open state is restricted by a lock mechanism (not shown). Thus, the landing door 36 normally blocks between the landing 18 side and the hoistway 12 side. The landing door 36 is unlocked by the lock mechanism in conjunction with the car 14 arriving at the destination floor and the car door 34 is moved from the closed state to the open state, and is changed from the closed state to the open state. .

  Each landing 18 is provided with a landing operating panel 38 connected to the control panel 50 via a wireless or wired network. The platform operating panel 38 is an input device that is operated when a user calls the car 14 to the platform 18 where the user is located. Similarly, the car 14 is provided with an in-car operation panel 40. The in-car operation panel 40 is an input device used when a user who has entered the car 14 designates a destination floor or opens / closes the car door 34.

  The car 14 has, for example, a box shape in which a user and luggage can be placed, and a car opening 14 a that allows the user and luggage to enter and exit is formed between the inside of the car 14 and the landing 18. Has been. An openable / closable car door 34 is provided so as to close the car opening 14a.

  The counterweight 20 is a counterweight connected to the car 14 via the main rope 22 and moves up and down in conjunction with the car 14 in the hoistway 12. The counterweight 20 moves up and down along a weight guide rail (not shown). The counterweight 20 is placed between the car 14 and the hoisting machine 24 disposed in the machine room 32 when the car 14 has a predetermined load (for example, about 1/2 of the maximum load). Weight is set to balance with. The main rope 22 is hung on the main sheave 28 and the deflector sheave 30 of the hoisting machine 24 provided at the upper part of the hoistway 12, and the car 14 is connected to one end and the counterweight 20 is connected to the other end. By connecting the two,

  The hoisting machine 24 includes, for example, a motor 26 and a main sheave 28 connected to the motor 26, and winds up the main rope 22 with power generated by the motor 26. The hoisting machine 24 can be driven and controlled by a control panel 50 disposed in the machine room 32.

  The control panel 50 is prepared in advance, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores a predetermined control program in advance, a RAM (Random Access Memory) that temporarily stores the calculation results of the CPU. A microcomputer having a backup RAM for storing information such as reference data and elevator 10 specifications and an input / output port device, a drive circuit, and the like. The control panel 50 is electrically connected to various parts of the various sensors, detectors, and elevators 10, and controls the operation of each part in an integrated manner. Depending on the specifications of the elevator 10, the machine room 32 may not be provided. In this case, the control panel 50 may be installed on the wall surface of the hoistway 12 or a three-way frame.

<Embodiment 1>
FIG. 2 is a functional block diagram of an elevator system including the elevator control device according to the first embodiment, and includes details of the control panel 50.

  The control panel 50 includes a car call registration unit 52, an operation control unit 54, a mode control device 56 (elevator control device), and the like. The car call registration unit 52 is used for the hall call registration SW (switches) of the hall operation panels 38 (38 (1), 38 (2),..., 38 (n-1), 38 (n)) provided in each hall 18. ) Register information corresponding to the hall call registration input by the user via 38a (call input unit). The landing call registration SW 38a is, for example, a button or a switch on a touch panel, but is not limited thereto. Also, the car call registration unit 52 is a car call that is input by the user to designate a destination floor via the in-car call registration SW (switch) 40a of the in-car operation panel 40 provided in the car 14. Register the information corresponding to the registration. The car call registration SW 40a is, for example, a button or a switch on a touch panel, but is not limited thereto. The operation control unit 54 determines the rotation direction and rotation speed of the motor 26 of the hoisting machine 24 according to the landing call registration and car call registration registered in the car call registration unit 52 and the mode state of the mode control unit 64 (control unit). The car 14 is operated by controlling the rotation amount, the braking state, and the like.

  The mode control device 56 includes a specific user determination unit 58 (determination unit), a specific user car call determination unit 60, a mode switching determination unit 62 (mode switching unit), a mode control unit 64, a notification unit 66, and the like. The mode control unit 64 includes a normal operation mode control unit 64a, an inspection mode control unit 64b, a temporary operation mode control unit 64c, and the like.

  The normal operation mode control unit 64a is a control unit that executes a normal operation mode in which the elevator 10 performs normal operation. In the normal operation mode, when the user of the elevator 10 performs call registration of the car 14 via the hall operation panel 38 or the in-car operation panel 40, the hall 18 where the car 14 is operated at high speed and the call is registered. This is a control mode in which the car 14 is moved efficiently.

  The inspection mode control unit 64b is a control unit that executes the inspection mode in which the normal operation mode is stopped and maintenance operation is performed instead when the maintenance inspection operation is performed. The inspection mode is a control mode in which the car 14 can be driven at a lower speed than in the normal operation mode, or the car 14 can be stopped at the position of the landing 18 or a position shifted from the landing 18 by the operator's operation. In addition, during the execution of the inspection mode, normal operations from the landing operation panel 38 and the in-car operation panel 40 are basically not accepted.

  The temporary operation mode control unit 64c is a mode for placing the specific user on the car 14 during the execution of the inspection mode, and when the specific user meets the predetermined condition after moving to the destination floor It is a control part which performs temporary operation mode which returns to inspection mode. The “specific user” is a user who is specifically permitted to use the elevator 10 even during the maintenance and inspection work of the elevator 10, and includes, for example, a wheelchair user who is difficult to use stairs or the like, a traffic weak person, and the like. The temporary operation mode is a platform where the specific user exists (for example, the standard floor: the first floor 16 (1) only when the worker permits the operation that the elevator 10 is in no problem even if the specific user is in operation. )) Is a control mode in which the car 14 can be operated in substantially the same state (speed) as the normal operation mode in response to only car call registration. The temporary operation mode is a control mode in which the control mode is automatically returned to the inspection mode when the response to the call registration during the temporary operation mode is completed.

  The specific user determination unit 58 determines whether or not “specific user” exists on the reference floor based on the detection result of the specific user detection unit 68 provided on the first floor 16 (1) which is the reference floor. To do. The specific user detection unit 68 is, for example, an imaging device or a laser sensor provided in the vicinity of the landing operation panel 38 of the landing 18 on the reference floor (first floor 16 (1)). An image of an object existing in the image is taken or a shape is acquired. Further, the specific user detection unit 68 may be an IC tag reader or the like. The specific user detection unit 68 is connected to the control panel 50 via a wireless or wired network.

  When the specific user detection unit 68 is an imaging device or a laser sensor, the specific user determination unit 58 can determine a specific user whose acquired information (captured image and shape information) is stored in advance in a storage unit (not shown). It is determined whether or not the user is a specific user. For example, when the determination information is “wheelchair”, if the acquired information includes a shape indicating “wheelchair”, the specific user determination unit 58 determines that there is a specific user at the landing 18. When the specific user detection unit 68 is an IC tag reader, the IC tag reader reads the contents of the IC tag possessed by the user at the landing 18 on the reference floor (first floor 16 (1)). The specific user determination unit 58 compares the read IC tag information with registration information that can be stored in advance in the storage unit to identify the specific user, and determines whether the IC tag holder is a registered specific user. Determine whether. The IC tag is given in advance to a person who satisfies a predetermined condition from a manager of the building or the elevator 10 or the like. The specific user detection unit 68 is not limited to an imaging device, a laser sensor, an IC tag reader, or the like, and may be any device that can acquire information that can identify a specific user.

  The specific user car call determination unit 60 determines the determination result of the specific user determination unit 58 and the landing operation panel 38 (38 (1)) on the reference floor (the first floor 16 (1)) registered in the car call registration unit 52. ) To determine whether or not the specific user has registered for the landing call on the reference floor (the first floor 16 (1)). That is, the specific user car call determination unit 60 determines whether or not the user satisfies a condition that allows the elevator 10 to be used during the maintenance and inspection work. For example, even when the hall call registration is performed on the hall operation panel 38 (38 (1)) on the standard floor (the first floor 16 (1)), the specific user determination unit 58 determines that the users on the standard floor are not. When it is determined that the user is a specific user, the specific user car call determination unit 60 performs a “negative determination”. That is, the specific user car call determination unit 60 determines that the user on the reference floor is not a right holder who can use the elevator 10 during the maintenance inspection work. On the other hand, when the ride is called and registered on the platform operation panel 38 (38 (1)) on the reference floor, the specific user determination unit 58 determines that the user on the reference floor is the specific user. In this case, the specific user car call determination unit 60 performs “affirmation determination”. That is, the specific user car call determination unit 60 determines that the user on the reference floor is a right holder who can use the elevator 10 during the maintenance inspection work.

  The mode switching determination unit 62 determines the operation state of the inspection mode SW (switch) 70 or the mode switching operation unit 72 operated by the operator, and indicates the operation state currently requested for the elevator 10 to the mode control unit 64. A signal to notify is output. The inspection mode SW 70 is a select switch or toggle switch for maintenance inspection work for switching between the normal operation mode and the inspection mode, and a position where the operator may start the maintenance inspection work, for example, a machine The control panel 50 of the room 32 and the vicinity thereof, the car room of the car 14, the ceiling, the landing 18 and the like are arranged. The inspection mode SW 70 is connected to the control panel 50 via a wireless or wired network. The inspection mode SW 70 is preferably locked so that only an operator can operate it. The mode switching operation unit 72 is a select switch, a toggle switch, or the like that is operated by an operator when switching to the temporary operation mode during execution of the inspection mode. The mode switching operation unit 72 is also disposed at a position where the operator may perform maintenance and inspection work, for example, at the control panel 50 of the machine room 32 or a position near the control panel 50. Moreover, in another Example, you may arrange | position in the passenger compartment 18 grade | etc., In the cage | basket | car interior of the passenger car 14, on the ceiling. The mode switching operation unit 72 is connected to the control panel 50 via a wireless or wired network. It is desirable that the mode switching operation unit 72 is also locked so that only an operator can operate.

  The mode control unit 64 controls the operation control unit 54 in the control mode based on the determination result of the mode switching determination unit 62 and realizes the operation of the car 14. The temporary operation mode control unit 64c of the mode control unit 64 acquires information on whether or not there is a car call registration by the specific user from the specific user car call determination unit 60 during the execution of the special operation mode. When the car call registration by the specific user no longer exists, the control mode is returned to the inspection mode.

  When the specific user car call determination unit 60 makes an “affirmation determination”, that is, when it is determined that there is a specific user who can use the elevator 10 during the maintenance and inspection work, the determination result is provided to the notification unit 66. The notification unit 66 outputs information indicating that the specific user exists on the reference floor (the first floor 16 (1)) to the notification output unit 74. The notification output unit 74 is, for example, an audio output device (speaker, buzzer, etc.) or a display device (monitor, indicator lamp, LED, etc.) provided at a place where an operator (maintenance worker) is working. The notification output unit 74 is connected to the control panel 50 via a wireless or wired network, and is disposed in the vicinity of the control panel 50 of the machine room 32 where an operator can work. In addition, when the mode switching operation unit 72 is provided at a plurality of positions, it is desirable that the notification output unit 74 is also provided. The notification content can be a voice announcement indicating that a car call has been registered by a specific user, or a notification sound by a buzzer. Moreover, you may alert | report by lighting of an indicator lamp or LED.

  When the notification by the notification output unit 74 is performed, the worker operates the mode switching operation unit 72 and operates the temporary operation mode control unit if the current state of the elevator 10 is a state in which the specific user can be carried. 64c can be switched to the temporary operation mode. The notification output unit 74 may display information indicating whether or not the current state of the elevator 10 may be operated in the temporary operation mode. In this case, the criteria for switching to the temporary operation mode are clarified, and variations in judgment among workers can be prevented.

  An example of the operation of the elevator control device (mode control device 56) of the first embodiment configured as described above will be described with reference to the flowchart of FIG.

  Based on the operation state of the inspection mode SW 70, the mode switching determination unit 62 determines whether or not the current control mode state is the inspection mode (S100). When it is determined that the current control mode is not the inspection mode but the normal operation mode (No in S100), a signal indicating the state is provided to the mode control unit 64, and this flow is temporarily terminated. That is, the mode control unit 64 controls the operation control unit 54 by the normal operation mode control unit 64a. When the current control mode is the inspection mode (Yes in S100), that is, when the inspection mode SW 70 is operated by the operator so that the maintenance inspection work can be performed, a signal indicating the state is sent to the mode control unit. 64. In this case, the mode control unit 64 controls the operation control unit 54 by the inspection mode control unit 64b. Then, the specific user determination unit 58 determines whether there is a specific user on the reference floor based on the detection information of the specific user detection unit 68 (S102). When the specific user does not exist on the reference floor (No in S102), a signal indicating the state is provided to the specific user car call determination unit 60, and this flow is once ended. In this case, the specific user car call determination unit 60 makes a “negative determination”. That is, the mode control unit 64 continues the control of the operation control unit 54 by the inspection mode control unit 64b.

  When the specific user determination unit 58 determines that the specific user exists on the reference floor (Yes in S102), the specific user car call determination unit 60 provides a signal indicating the state to the specific user car call determination unit 60. 60 determines whether or not landing call registration has been performed on the reference floor in the car call registration unit 52 (S104). When the car call registration unit 52 does not provide a signal indicating the landing call registration on the reference floor (No in S104), the specific user car call determination unit 60 makes a “negative determination” and once ends this flow. That is, the mode control unit 64 continues the control of the operation control unit 54 by the inspection mode control unit 64b. On the other hand, when a signal indicating landing call registration is provided on the reference floor from the car call registration unit 52 (Yes in S104), the specific user car call determination unit 60 performs “affirmation determination” and notifies the notification unit 66 Provide a positive determination result. In this case, the notification unit 66 works a message indicating that there is a specific user who is permitted to use the elevator 10 during execution of the inspection mode on the reference floor for the worker via the notification output unit 74. The information is output (notified) to the person (S106).

  The specific user does not always operate the landing call registration SW 38a. For example, when the specific user is a wheelchair user, an attendant or a non-specific user present there may operate the landing call registration switch 38a. In the first embodiment and the following embodiment, when there is a specific user on the reference floor, even if a person other than the specific user operates the landing call registration switch 38a, the specific user operates it. Is considered.

  The mode switching determination unit 62 determines whether or not the operator has performed switching operation to the temporary operation mode via the mode switching operation unit 72 (S108). Even when the notification is given by the notification output unit 74, the worker is in a state where the current state of the elevator 10 is not switched to the temporary operation mode. If it is being canceled, the mode switching operation unit 72 is not operated. Further, the notification output unit 74 may output information indicating that the operation of the mode switching operation unit 72 is prohibited to alert the operator. When the mode switching determination unit 62 cannot acquire an operation signal from the mode switching operation unit 72 within a predetermined period (No in S108), the mode switching is temporarily terminated. In this case, the mode control unit 64 continues the control of the operation control unit 54 by the inspection mode control unit 64b.

  The mode switching determination unit 62 switches the control mode (control state) to the temporary operation mode for the mode control unit 64 when an operation signal can be acquired from the mode switching operation unit 72 within a predetermined period (Yes in S108). Is output (S110). That is, the mode switching determination unit 62 also functions as a “mode switching unit”.

  When the switching command is received from the mode switching determination unit 62, the control of the mode control unit 64 is switched from the control of the inspection mode control unit 64b to the control of the temporary operation mode control unit 64c, and the operation control unit 54 is driven in the temporary operation mode. The car 14 is operated (S112). That is, the car 14 is operated (moved) at a high speed substantially the same as that in the normal operation mode toward the reference floor where the specific user has registered the landing call. Furthermore, when the specific user enters the car 14 and registers the car call by the in-car call registration SW 40a for moving to the destination floor, the operation control unit 54 responds to the car call registration and sets the car 14 in response. Operate to the destination floor. Then, when the car 14 arrives at the destination floor, the operation control unit 54 opens the car door 34 of the car 14 and the landing door 36 of the destination floor for a predetermined period, and then closes it (S114). Until the opening / closing operation of the landing door 36 and the car door 34 on the destination floor can be confirmed (No in S114), the operation control unit 54 continues the operation of the car 14 in the temporary operation mode. On the other hand, when the opening / closing operation of the landing door 36 and the car door 34 on the destination floor can be confirmed (Yes in S114), the temporary operation mode control unit 64c returns the control mode to the inspection mode (S116), and a series of End the flow. That is, when the response to the specific user's car call registration is completed, the mode control unit 64 automatically returns to the inspection mode. In this case, the predetermined condition for returning from the temporary operation mode to the inspection mode is “the opening / closing operation of the landing door 36 and the car door 34 on the destination floor has been completed”.

  As described above, according to the first embodiment, when the elevator 10 is operating in the inspection mode and the landing call registration is received by the specific user, the operator operates the mode switching operation unit 72. When the operation in the temporary operation mode is permitted, the inspection mode is promptly switched to the temporary operation mode. And the operation control part 54 moves the passenger car 14 in the operation mode similar to the normal operation mode, and carries the specific user to the destination floor. As a result, the use waiting time of the elevator 10 of the specific user can be shortened, and the confusion and annoyance of the specific user can be easily reduced. In addition, after carrying the specific user to the destination floor, the mode automatically returns to the inspection mode, so that the worker who has temporarily suspended the maintenance inspection work to permit the specific user to use the elevator 10 is After the use of the specific user of the elevator 10 is completed, the maintenance and inspection work can be resumed smoothly.

  Even when it is notified through the notification unit 66 that the specific user has registered for the landing call on the reference floor, it is not preferable to switch to the temporary operation mode depending on the state of the inspection work of the elevator 10. There is. In this case, the inspection mode is continued and the operation of the elevator 10 is stopped. In such a case, the worker may explain the situation to a specific user on the reference floor through an interphone or the like to obtain an understanding.

<Embodiment 2>
FIG. 4 is a functional block diagram of an elevator system including the elevator control apparatus according to the second embodiment, and includes details of the control panel 50. The basic configuration is the same as that of the first embodiment shown in FIG. 2, and the same reference numerals are given to the same configuration, and detailed description thereof is omitted.

  In the mode control device 56 of the second embodiment, in addition to the configuration of the first embodiment, the car 14 responds to the reference floor landing call and further responds to the car call registration of the specific user during execution of the temporary operation mode. Then, after moving to the destination floor, a return determination unit 76 for detecting whether or not the vehicle is on the reference floor (returned) is provided. For example, a reference floor car detection unit 78 provided at a position corresponding to the reference floor in the hoistway 12 is connected to the return determination unit 76 via a wired or wireless network. As the reference floor car detection unit 78, for example, an image sensor or a sensor such as a photoelectric switch can be used. When the reference floor car detection unit 78 is an imaging device, the captured image is provided to the return determination unit 76, and the return determination unit 76 performs image analysis or the like to determine whether the car 14 exists on the reference floor. To do. When the reference floor car detection unit 78 is a sensor such as a photoelectric switch, the sensor signal is provided to the return determination unit 76 to determine whether or not the car 14 exists on the reference floor.

  When the return determination unit 76 detects that the car 14 is on the reference floor (returned) after the car 14 responds to the landing call registration and the car call registration during the execution of the temporary operation mode, Is provided to the temporary operation mode control unit 64c. The temporary operation mode control unit 64c determines that the response to the car call registration of the specific user has been completed, and executes a process of returning the control mode to the inspection mode. Therefore, when the return determination unit 76 detects the return of the car 14 to the reference floor, the operation control unit 54 thereafter operates the car 14 in the inspection mode. The return operation in the temporary operation mode can be controlled by the temporary operation mode control unit 64c.

  FIG. 5 is a flowchart illustrating an example of the operation of the elevator control device (mode control device 56) according to the second embodiment. The process of switching from the inspection mode to the temporary operation mode and operating the car 14 in the temporary operation mode is the same as the process of the first embodiment described with reference to FIG. Therefore, the same processing is given the same step number, and detailed description thereof is omitted.

  As described above, in the flowchart of FIG. 5, the processing from S100 to S114 is the same as the processing of the flowchart of FIG. In S114, when the opening / closing operation of the landing door 36 and the car door 34 on the destination floor can be confirmed (Yes in S114), the temporary operation mode control unit 64c performs the return operation of the car 14 so as to execute the return operation. A command signal is supplied to 54. The operation control unit 54 executes the return operation by controlling the rotation direction, rotation speed, rotation amount, braking state, etc. of the motor 26 of the hoisting machine 24 so as to quickly move the car 14 to the reference floor ( S200).

  The return determination unit 76 determines whether or not the car 14 has returned to the reference floor based on the detection result (captured image or sensor signal) provided from the reference floor car detection unit 78 (S202). When the return (return information) of the car 14 cannot be detected (No in S202), the temporary operation mode control unit 64c continues the return operation control. On the other hand, when the return determination unit 76 detects the return of the car 14 to the reference floor (Yes in S202), the temporary operation mode control unit 64c returns the control mode to the inspection mode (S204), and a series of flows End. That is, when the response to the car call registration of the specific user is completed and the car 14 returns to the reference floor, the mode control unit 64 automatically returns to the inspection mode. In this case, the predetermined condition for returning from the temporary operation mode to the inspection mode is “the car 14 returned to the reference floor after responding to the landing call registration and the car call registration during the execution of the temporary operation mode”. It becomes.

  As described above, according to the second embodiment, when the elevator 10 is operating in the inspection mode and the landing call registration is received by the specific user, the operator operates the mode switching operation unit 72. When the operation in the temporary operation mode is permitted, the inspection mode is promptly switched to the temporary operation mode. And the operation control part 54 moves the passenger car 14 in the operation mode similar to the normal operation mode, and carries the specific user to the destination floor. As a result, the use waiting time of the elevator 10 of the specific user can be shortened, and the confusion and annoyance of the specific user can be easily reduced. In addition, after the specific user is brought to the destination floor, when the car 14 returns to the reference floor, it automatically returns to the inspection mode. Therefore, the maintenance inspection work is performed to allow the specific user to use the elevator 10. The worker who has temporarily suspended the vehicle can resume the maintenance and inspection work smoothly without adjusting the position of the car 14 after the use of the elevator 10 by the specific user is completed.

  In the above description, an example in which a dedicated reference floor car detection unit 78 is provided for detection of return in the temporary operation mode has been described. However, an apparatus that detects the position of the existing car 14 in the elevator 10 is used. May be. For example, the hoistway 12 may be provided with a limit switch at a position corresponding to each landing 18, and the car 14 may be provided with an operating body (sometimes referred to as a “dressing plate”) for operating the limit switch. . In addition, the motor 26 includes a pulse generator that outputs a signal indicating an operation state. Accordingly, the return determination unit 76 can detect the position of the car 14 based on the output signal of the limit switch operated by the landing plate and the output signal of the pulse generator, and the car 14 returns to the reference floor. It is possible to determine whether or not a captured image is used, and the same effect as when a captured image is used can be obtained.

<Embodiment 3>
FIG. 6 is a functional block diagram of an elevator system including the elevator control device according to the third embodiment, and includes details of the control panel 50. The basic configuration is the same as that of the second embodiment shown in FIG. 4, and the same reference numerals are given to the same configuration, and detailed description thereof is omitted.

  In addition to the configuration of the second embodiment, the mode control device 56 of the third embodiment further includes an in-car occupant determination unit 80 that detects whether there is an occupant (user) in the car 14. An occupant detection unit 82 disposed in the car 14 is connected to the in-car occupant determination unit 80 via a wired or wireless network. An imaging device, a weight sensor, or the like can be used as the occupant detection unit 82. When the occupant detection unit 82 is an imaging device, the captured image is provided to the in-car occupant determination unit 80, and the in-car occupant determination unit 80 performs image analysis or the like to determine whether there is an occupant in the car 14. Determine. When the occupant detection unit 82 is a sensor such as a weight sensor, a sensor signal is provided to the in-car occupant determination unit 80, and the car 14 is heavier than a weight when the car 14 is "empty". It is determined that there are passengers inside.

  When the occupant determination unit 80 detects that there is no occupant in the car 14 during execution of the temporary operation mode, the occupant determination unit 80 provides a signal indicating the state to the temporary operation mode control unit 64c. The temporary operation mode control unit 64c determines that the response to the car call registration of the specific user has been completed by acquiring the signal, and executes processing for returning the control mode to the inspection mode. Therefore, the mode control unit 64 acquires a signal indicating that no occupant is present in the car 14 during the execution of the temporary operation mode, and when the car 14 returns to the reference floor, the car thereafter. 14 will be operated in the inspection mode.

  By providing the in-car occupant determination unit 80, it is easy to finish responding to the car call registration of the user in the car 14 even when a non-specific user has entered the car 14 together with the specific user. Can be detected. For example, when a specific user intends to use the elevator 10, there are cases where the user himself / herself operates the landing call registration switch 38a on the reference floor, and when there is an attendant, the attendant may operate. In addition, a non-specific user (third party) who is present with a specific user may operate on behalf of the specific user. Even in such a case, the elevator 10 can be operated in the temporary operation mode, and a specific user can get into the car 14. In this case, it is unreasonable to move only a specific user to the destination floor in the car 14, and to the specific user and his / her attendant, as well as non-specific users present there It is reasonable to get on the car 14 operated in the temporary operation mode. The in-car occupant determination unit 80 detects all occupants other than the specific user, so that all the occupants including the specific user and the non-specific users present around the specific user have exited the car 14. In this case, the temporary operation mode can be returned to the inspection mode.

  FIG. 7 is a flowchart illustrating an example of the operation of the elevator control device (mode control device 56) according to the third embodiment. The process of switching from the inspection mode to the temporary operation mode and operating the car 14 in the temporary operation mode is the same as the process of the first embodiment described with reference to FIG. Therefore, the same processing is given the same step number, and detailed description thereof is omitted.

  As described above, in the flowchart of FIG. 7, the processing from S100 to S112 is the same as the processing of the flowchart of FIG. In S112, the car occupant determination unit 80 always detects presence / absence information indicating whether or not there is no occupant in the car 14 in a state where the car 14 is operated in the temporary operation mode (S300). When the occupant determination unit 80 determines that there is an occupant in the car 14 (No in S300), the operation of the car 14 in the temporary operation mode is continued. That is, all the passengers on the car 14 are carried to the destination floor. On the other hand, if the in-car occupant determination unit 80 determines that there is no occupant in the car 14 (Yes in S300), the temporary operation mode control unit 64c performs other operations on the reference floor during operation in the temporary operation mode. It is determined whether there is no landing call registration (S302). For example, when the stop and operation are repeated on a plurality of floors corresponding to the car call registration registered by a specific user or a non-specific user, the elevator 10 appears to be operating normally. If a non-specific user is waiting on the reference floor during this time, it will be unreasonable that the user will not be able to get on the car 14 after returning to the inspection mode despite waiting for the car 14 for a long time. Therefore, if there is a landing call registration on the reference floor during operation in the temporary operation mode (No in S302), the process proceeds to S112 and the operation in the temporary operation mode is continued. That is, use of the elevator 10 is permitted to a user who has been waiting on the reference floor during execution of the temporary operation mode regardless of whether or not the user is a specific user.

  In S302, when there is no landing call registration on the reference floor during operation in the temporary operation mode (Yes in S302), the temporary operation mode control unit 64c causes the operation control unit 54 to execute the return operation of the car 14. Supply command signal. The operation control unit 54 executes the return operation by controlling the rotation direction, rotation speed, rotation amount, braking state, etc. of the motor 26 of the hoisting machine 24 so as to quickly move the car 14 to the reference floor ( S304).

  The return determination unit 76 determines whether or not the car 14 has returned to the reference floor based on the detection result provided from the reference floor car detection unit 78 (S306). When the return of the car 14 cannot be detected (No in S306), the temporary operation mode control unit 64c continues the return operation control. On the other hand, when the return determination unit 76 detects the return of the car 14 to the reference floor (Yes in S306), the temporary operation mode control unit 64c returns the control mode to the inspection mode (S308), and a series of flows End. That is, when the use of all the users existing on the reference floor is completed during execution of the temporary operation mode and the car 14 returns to the reference floor, the mode control unit 64 automatically returns to the inspection mode. In this case, the predetermined condition for returning from the temporary operation mode to the inspection mode is “use of all the users existing on the reference floor during the execution of the temporary operation mode has been completed and returned to the reference floor of the car 14. It will be.

  As described above, according to the third embodiment, when the elevator 10 is operating in the inspection mode and the landing call registration is received by the specific user, the operator operates the mode switching operation unit 72. When the operation in the temporary operation mode is permitted, the inspection mode is promptly switched to the temporary operation mode. Then, the operation control unit 54 moves the car 14 in the same operation mode as in the normal operation mode, and carries all the users who are present on the reference floor including the specific user to the destination floor. As a result, it is possible to reduce the waiting time for the elevator 10 of the specific user who is on the reference floor and the user who is on the reference floor during operation in the temporary operation mode, and the standard during operation in the specific user or temporary operation mode. It becomes easy to reduce the confusion and annoyance of the user who was on the floor. In addition, since all the users who were on the standard floor during operation in the temporary operation mode are carried to the target floor and then automatically return to the inspection mode, the operator will be informed whenever the landing call registration is performed on the standard floor. There is no need to respond, and the worker who has temporarily suspended the maintenance and inspection work to allow the specific user to use the elevator 10 can resume the maintenance and inspection work smoothly after the use of the specific user is completed. it can.

<Embodiment 4>
FIG. 8 is a functional block diagram of an elevator system including the elevator control apparatus according to the fourth embodiment, and includes details of the control panel 50. The basic configuration is the same as the configuration of the third embodiment shown in FIG. 6, and the same reference numerals are given to the same configuration, and detailed description thereof is omitted.

  The specific user determination unit 58 of the mode control device 56 of the fourth embodiment includes specific user detection units 68 (68 (1), 68 (2),..., 68 () provided at the landing 18 on each floor 16. n-1) and 68 (n)) are connected. That is, the specific user determination unit 58 determines whether or not there is a specific user at each landing 18. Each embodiment mentioned above showed the example which enables operation of the elevator 10 in temporary operation mode, only when a specific user exists in a reference floor. In this case, for example, when the specific user who has returned from the outside room returns to his / her home, the troublesomeness when the elevator 10 cannot be used in the inspection mode can be eliminated. On the other hand, the fourth embodiment is an example that enables operation in the temporary operation mode even when a specific user moves between the landings 18 to the upper floor or the lower floor. In this case, if only non-specific users are allowed to operate in the temporary operation mode until they register at the landing call outside the standard floor, the maintenance and inspection work interrupted by the execution of the temporary operation mode takes a long time. . Therefore, in the present embodiment, the operation in the temporary operation mode is enabled only when there is a specific user other than the reference floor.

  FIG. 9 is a flowchart illustrating an example of the operation of the elevator control device (mode control device 56) according to the fourth embodiment. The process of switching from the inspection mode to the temporary operation mode and operating the car 14 in the temporary operation mode is the same as the process of the third embodiment described with reference to FIG. Therefore, the same processing is given the same step number, and detailed description thereof is omitted.

  As described above, in the flowchart of FIG. 9, the processes of S100 to S112 and S300 other than the processes of “No in S102” and “No in S104” are the same as the processes in the flowchart in FIG. In S102, when there is no specific user on the reference floor (No in S102), the specific user determination unit 58 determines whether there is a specific user on the landing 18 on the other floor 16 or not. A determination is made based on the detection result of the user detection unit 68 (68 (1), 68 (2),..., 68 (n−1), 68 (n)) (S400). When there is no specific user other than the reference floor (No in S400), a signal indicating the state is provided to the specific user car call determination unit 60, and this flow is once ended. In this case, the specific user car call determination unit 60 makes a “negative determination”. That is, the mode control unit 64 continues the control of the operation control unit 54 by the inspection mode control unit 64b. In S400, when the specific user exists on the floor 16 other than the reference floor (Yes in S400), a signal indicating the state is provided to the specific user car call determination unit 60. In this case, the specific user car call determination unit 60 performs “affirmation determination”. At this time, in the car call registration unit 52, when the hall call registration is registered on the floor 16 where the specific user exists (Yes in S400), the process proceeds to S106, and the notification unit 66 sets the notification output unit 74. The message indicating that the specific user exists outside the reference floor is notified to the worker. That is, when there is a specific user at any of the landings 18, it is possible to switch to the temporary operation mode. On the other hand, in the car call registration unit 52, when the landing call registration is not registered on the floor 16 where the specific user exists (No in S400), a signal indicating the state is provided to the specific user car call determination unit 60. Once this flow is finished. In this case, the specific user car call determination unit 60 makes a “negative determination”. That is, the mode control unit 64 continues the control of the operation control unit 54 by the inspection mode control unit 64b. In S104, when there is no landing call registration on the reference floor (No in S104), the process proceeds to S400, the other floor 16 is confirmed, and the subsequent processing is executed.

  In S300, when the car occupant determination unit 80 determines that no passenger is present in the car 14 (Yes in S300), the specific user car call determination unit 60 determines that all the floors 16 in which the specific user exists exist. In step S404, it is determined whether or not the landing call registration has been answered. When there is a landing call registration that has not been answered, the process proceeds to S112, and the temporary operation mode control unit 64c responds to the remaining landing call registration via the operation control unit 54.

  In S404, when the specific user car call determination unit 60 determines that it has responded to the landing call registration at all floors 16 where the specific user exists (Yes in S404), the temporary operation mode control unit 64c A command signal is supplied to the operation control unit 54 so as to execute 14 return operations. The operation control unit 54 controls the rotation direction, the rotation speed, the rotation amount, the braking state, and the like of the motor 26 of the hoisting machine 24 so as to quickly move the car 14 to the reference floor (S406).

  The return determination unit 76 determines whether or not the car 14 has returned to the reference floor based on the detection result provided from the reference floor car detection unit 78 (S408). When the return of the car 14 cannot be detected (No in S408), the temporary operation mode control unit 64c continues the return operation control. On the other hand, when the return determination unit 76 detects the return of the car 14 to the reference floor (Yes in S408), the temporary operation mode control unit 64c returns the control mode to the inspection mode (S410), and a series of flows End. That is, when the car 14 returns to the reference floor and the use of the elevator 10 of all users who have been waiting for the car 14 together with the specific user and the specific user during the execution of the temporary operation mode is completed, the mode control unit 64 automatically Return to inspection mode. In this case, the predetermined condition for returning from the temporary operation mode to the inspection mode is “specific users existing on all floors during execution of the temporary operation mode and all users waiting for the car 14 together with the specific users. Has been completed and has returned to the reference floor of the car 14 ”.

  As described above, according to the fourth embodiment, when the elevator 10 is operating in the inspection mode and the landing call registration is received by the specific user, the operator operates the mode switching operation unit 72. When the operation in the temporary operation mode is permitted, the inspection mode is promptly switched to the temporary operation mode. Then, the operation control unit 54 moves the car 14 in the same operation mode as in the normal operation mode, and carries all the users who have waited for the car 14 together with the specific user and the specific user to the destination floor. As a result, the use waiting time of the elevator 10 can be shortened for all the users who have been waiting for the elevator 10 together with the specific user and the specific user in any floor 16, and the trouble caused by the waiting of the elevator 10 It becomes easy to reduce annoyance. In addition, since the specific user and all users who have been waiting for the elevator 10 together with the specific user are brought to the target floor and automatically return to the inspection mode, the worker who has temporarily suspended the maintenance inspection work Maintenance inspection can be resumed smoothly.

  In the second, third, and fourth embodiments described above, an example is shown in which the temporary operation mode control unit 64c returns to the inspection mode when the car 14 returns to the reference floor. In another embodiment, after the return to the inspection mode, the place where the car 14 was located when the control mode was switched from the inspection mode to the temporary operation mode based on the registration of the specific user's landing call (for inspection) The car 14 may be automatically returned to the stop position). In another embodiment, when the car call registration of a specific user or a user who has been waiting for the car 14 together with the specific user is completed, the car 14 is moved to a position where the car 14 has been stopped for inspection. And the control mode may be returned to the inspection mode. In this case, it is possible to resume more smoothly from the state in which the maintenance and inspection work that has been interrupted by the execution of the temporary operation mode is interrupted.

  Further, when the elevator 10 is operated in the temporary operation mode, the operator may be able to confirm the state in the landing 18 or the car 14. For example, the image acquired by the specific user detection unit 68 or the occupant detection unit 82 may be displayed in the vicinity of the worker or on a portable display device. Further, when the elevator 10 is operated in the temporary operation mode, a conversation with a specific user or the like may be possible. In this case, it is possible to easily confirm safety during operation in the temporary operation mode.
