Description

Technical Field

[0001] This invention relates to an elevator control device, an elevator, and a method for controlling the control panel inside the car. Background Technology

[0002] In recent years, elevators have been provided with destination floor registration devices installed in the elevator lobby. Patent Document 1 describes an elevator registration device comprising: a tag carried by a passenger, which stores the passenger's used floor as the destination floor registration floor and transmits the destination floor registration floor information to an antenna; and an antenna capable of receiving information from the tag in the elevator lobby and inside the elevator car.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2005-255320 Summary of the Invention

[0006] -The problem the invention aims to solve-

[0007] The elevator registration device described in Patent Document 1 makes a call when a person carrying a tag enters the sensing area of ​​the waiting hall, and registers the destination floor when the person enters the sensing area of ​​the car. Furthermore, the elevator control device determines the passenger's destination floor based on the destination floor registration information received by the antenna and the floor the car has arrived at, and illuminates the destination floor registration button corresponding to the determined destination floor to register it as the destination floor.

[0008] However, in recent years, from an aesthetic design perspective, the destination floor registration device (hereinafter also referred to as the car-in-car destination floor registration device) has been concealed from passengers' view by placing it inside the switch cabinet. In this case, where the car-in-car destination floor registration device, such as one installed inside the switch cabinet, is controlled as described in Patent Document 1, the destination floor registration button illuminates whenever a destination floor is registered. Furthermore, if the light from the illuminated destination floor registration button leaks out from the switch cabinet, it may cause a sense of unease or discomfort to passengers unaware of the presence of the car-in-car destination floor registration device.

[0009] Furthermore, the destination floor registration device inside the elevator car within the switchgear is envisioned to be operated by the building manager or maintenance personnel of the building equipped with the elevator. However, for example, if the registration of a destination floor that was intended to stop is cancelled due to the operation of the destination floor registration device by the manager or maintenance personnel, a situation may arise where the elevator does not reach the destination floor registered by the passenger inside the car.

[0010] This invention was made taking the above-mentioned situation into consideration. The object of this invention is to prevent inconvenience or adverse situations in elevators that have both a destination floor registration device in the lobby and a destination floor registration device installed in the car's control cabinet.

[0011] -Solution methods-

[0012] To solve the above problems and achieve the objectives of this invention, the elevator control device of this invention controls the operation of the elevator based on the control of a group management control device. The group management control device manages the operation of multiple elevators based on destination floor information registered by a destination floor registration device installed in the elevator lobby. The elevator control device includes: an in-car operation panel control unit that controls the operation of the in-car operation panel. The in-car operation panel has a destination floor information display unit that displays the registered destination floor information from the destination floor registration device in the elevator lobby, and is installed inside a switch cabinet within the elevator car. Furthermore, when the in-car operation panel control unit detects that the switch cabinet is open, it controls the lighting of the destination floor information display unit corresponding to the registered destination floor.

[0013] -Invention Effects-

[0014] According to the present invention, it is possible to prevent inconvenience or adverse conditions such as light leakage from the switch cabinet in elevators that have both a destination floor registration device in the waiting hall and an operating panel in the car installed in the switch cabinet.

[0023] Hereinafter, examples of embodiments for carrying out the present invention (hereinafter referred to as "implementations") will be described with reference to the accompanying drawings. The present invention is not limited to these embodiments; the various values, etc., in the embodiments are illustrative. Furthermore, in this specification and the accompanying drawings, structural elements having the same structural elements or substantially the same function are given the same reference numerals, and repeated descriptions are omitted.

[0024] <Structure of Elevator System>

[0025] First, refer to Figure 1 The overall structure of the elevator system 100 involved in this embodiment will be described. Figure 1 This is an overall structural diagram of an elevator system 100 according to one embodiment of the present invention.

[0026] like Figure 1 As shown, the elevator system 100 includes: elevators 1_1 to 1_n (n is a natural number of 2 or more), elevator control devices 2_1 to 2_n, group management control device 3, input / output main processing device 4, and waiting hall destination floor registration devices 5_1 to 5_m (m is a natural number of 2 or more).

[0027] Furthermore, in the following description, elevators 1_1 to 1_n will be collectively referred to as elevator 1 unless it is necessary to identify them separately, and elevator control devices 2_1 to 2_n will be collectively referred to as elevator control devices 2 unless it is necessary to identify them separately. Additionally, waiting hall destination floor registration devices 5_1 to 5_m will be collectively referred to as waiting hall destination floor registration devices 5 unless it is necessary to identify them separately.

[0028] [elevator]

[0029] The structure of elevator 1 will be explained using elevator 1_1 as an example. Since the structures of elevators 1_2 to 1_n are the same as those of elevator 1_1, their descriptions will be omitted here.

[0030] Elevator 1_1 includes a car 10_1. The car 10_1 carries passengers, goods, etc., and moves up and down within a lift channel (not shown) formed within a building. The top surface of the car 10_1 is connected to a main rope 12_1, at the end of which a counterweight 11_1 is provided. The main rope 12_1 is wound around a traction machine 13_1 and a guide sheave 14_1. Furthermore, the car 10_1 moves up and down within the lift channel by controlling the movement of the traction machine 13_1 via an elevator control device 2_1. In the following description, unless it is necessary to separately identify the cars 10_1 to 10_n, they will be collectively referred to as car 10.

[0031] The car 10_1 includes: a door 101_1, a destination floor display device 102_1 located on the upper right side of the door 101_1, and a destination floor registration device 103_1 inside the car. The destination floor display device 102_1 is composed of a panel such as an LCD (Liquid Crystal Display) or an organic EL (Electronic Luminescent) display, and displays information such as the floor to which the car 10_1 is registered as the intended destination floor.

[0032] The car-in destination registration device 103_1 includes: a display unit 110_1, an open button 111_1, an close button 112_1, a switch cabinet 113_1, and a car-in operation panel 114_1 stored in the switch cabinet 113_1.

[0033] The display unit 110_1 is composed of a panel such as an LCD or an OLED, which displays information such as arrows indicating the lifting direction of the car 10_1. The switch cabinet 113_1 is a box that is locked or unlocked by inserting a key into a keyhole (not shown).

[0034] The in-car operation panel 114_1, for example, is a touch panel that displays the destination floor button (an example of a destination floor information display unit) and detects passenger finger contact. Furthermore, the in-car operation panel 114_1 sends the destination floor information detected by the passenger's finger contact to the elevator control device 2_1. Additionally, based on the control of the elevator control device 2_1, the in-car operation panel 114_1 illuminates the destination floor button corresponding to the registered destination floor registered by the hall destination floor registration device 5.

[0035] In the following description, without needing to identify the switch cabinets 113_1 to 113_n separately, they are collectively referred to as switch cabinet 113, and without needing to identify the car control panels 114_1 to 114_n separately, they are collectively referred to as car control panels 114.

[0036] In addition, the control panel 114_1 inside the car is equipped with a dedicated switch 115_1 for switching between dedicated operation modes and a maintenance switch 116_1 for switching between maintenance operation modes. Dedicated operation is the operation that allows the car 10_1 to go directly to the floor designated as the dedicated operation destination floor (hereinafter also referred to as the dedicated operation destination floor). During dedicated operation, the car 10_1 does not stop at floors other than the dedicated operation destination floor.

[0037] Maintenance operation is performed during maintenance work on elevator 1 by maintenance personnel. Maintenance operation includes operations based on the maintenance personnel's actions, automatic diagnostic operations of elevator 1, etc. The lock / unlock switchgear 113_1 and the operation of the car control panel 114_1 are performed by maintenance personnel or building managers. In the following description, unless individual identification of dedicated switches 115_1 to 115_n is required, they will be collectively referred to as dedicated switches 115, and unless individual identification of maintenance switches 116_1 to 116_n is required, they will be collectively referred to as maintenance switches 116.

[0038] [Elevator Control System]

[0039] Elevator control devices 2_1 to 2_n, based on the control of group management control device 3, respectively control the lifting and lowering movements of elevators 1_1 to 1_n, the opening and closing movements of doors 101_1 to 101_n, and the display operations of destination floor display devices 102_1 to 102_n. Elevator control devices 2_1 to 2_n include in-car operation panel control units 21_1 to 1_n and operation control units 22_1 to 22_n. Furthermore, in the following description, unless it is necessary to separately identify the in-car operation panel control units 21_1 to 1_n, they will be collectively referred to as in-car operation panel control unit 21, and unless it is necessary to separately identify the operation control units 22_1 to 22_n, they will be collectively referred to as operation control unit 22.

[0040] The in-car control panel 21 controls the lighting / switching of the touch panel of the in-car control panel 114, and controls the display of destination floor buttons, maintenance operation buttons, etc. on the in-car control panel 114.

[0041] The operation control unit 22 controls the operation of the elevator 1 based on the control from the operation control unit 32 of the group management control device 3, or based on the destination floor information input from the elevator lobby destination floor registration device 5 from the input / output main processing device 4. For example, it controls the elevator to run to the destination floor registered as the destination floor and open the door (to provide service).

[0042] In addition, the operation control unit 22 also performs the following operation: based on the detection results obtained by load sensors (not shown), door photoelectric devices, etc. installed in the car 10, it determines whether there are passengers getting off the elevator from the car 10 or passengers getting on the elevator from the car 10, and controls the opening and closing of the door 101 based on the determination result.

[0043] Furthermore, in this embodiment, the elevator control device 2's car-side control unit 21 and / or operation control unit 22 perform the following controls (1) to (4):

[0044] (1) Control that illuminates the operating panel 114 inside the car when the switch cabinet 113 is in the open state and turns off the operating panel 114 inside the car after the switch cabinet 113 is in the closed state (Examples 1-4).

[0045] (2) Switching control for assigning or not assigning new calls from the destination floor registration device 5 in the waiting hall when the dedicated operation mode is enabled (Example 1: Refer to Figure 4 )

[0046] (3) Switching control for assigning or not assigning new calls from the destination floor registration device 5 in the waiting hall when the maintenance operation mode is enabled (Example 2: Refer to Figure 5 )

[0047] (4) Control of accepting or rejecting the registration cancellation action of the destination floor after it has been registered based on the operation of the control panel 114 in the car (Example 4: see Figure 7 )

[0048] (5) Adjustment and control of the opening time of door 101 when switch cabinet 113 is in the unlocked state (Example 5: Refer to Figure 8 ).

[0049] Regarding the control of (1) and (2) above (Example 1), refer to the following description. Figure 4 To describe in detail the control of (3) above (Example 2), refer to the following description. Figure 5 This will be described in detail. Regarding the control of (4) above (Example 4), refer to the following description. Figure 7 To describe in detail the control of (5) (Example 5), refer to the following description. Figure 8 Let me describe it in detail.

[0050] [Group Management and Control Device]

[0051] The group management control device 3 includes a destination floor registration processing unit 31 and an operation control unit 32. The destination floor registration processing unit 31 processes the allocation of calls (registering destination floors) to the appropriate elevator 1 based on destination floor information sent from the lobby destination floor registration device 5 or the car destination floor registration device 103, and the operation information of each elevator 1. Furthermore, if the destination floor manually registered via the car operation panel 114 matches the destination floor registered from the lobby destination floor registration device 5, the destination floor registration processing unit 31 also controls the allocation of calls to the elevator 1 with the manually registered destination floor to increase its priority (Example 3: see reference). Figure 6 ).

[0052] The operation control unit 32 controls the elevator 1 to run to the destination floor registered by the destination floor registration processing unit 31, and controls the operation of the elevator 1 during dedicated operation or maintenance operation.

[0053] [Input / Output Main Processing Unit]

[0054] The input / output main processing unit 4 performs tasks such as controlling the transmission of destination floor information sent from the destination floor registration devices 5_1 to 5_m in the waiting hall to the group management control unit 3, receiving elevator information allocated by the group management control unit 3 and transmitting the display content to the destination floor registration devices 5_1 to 5_m in the waiting hall.

[0055] [Wait Hall Destination Floor Registration Device]

[0056] The destination floor registration devices 5_1 to 5_m in the waiting hall are installed in the waiting hall. The information of the destination floor selected by the user or read from the user's IC (Integrated Circuit) card, portable terminal, etc., is sent to the group management control device 3 or elevator 1 via the input / output main processing device 4.

[0057] <Example of a destination floor registration device in an elevator lobby>

[0058] Next, refer to Figure 2 The installation example of the destination floor registration device 5 in the waiting hall will be explained. Figure 2 This is a diagram showing an example of the installation of the destination floor registration device 5 in the waiting hall at location P.

[0059] exist Figure 2In the example shown, elevator lobby destination floor registration devices 5_1 and 5_2 are installed near the entrance of elevator lobby P, elevator lobby destination floor registration device 5_3 is installed between elevators 1_1 and 1_2, and elevator lobby destination floor registration device 5_4 is installed between elevators 1_2 and 1_3. Users can register their desired floor as their destination floor by operating any of the elevator lobby destination floor registration devices 5, or by covering their IC card, portable terminal, etc., which are registered with the desired floor, with the reader (not shown) of the elevator lobby destination floor registration device 5.

[0060] <Example of Computer Hardware Architecture>

[0061] Next, refer to Figure 3 The hardware structure of the elevator control device 2 and the group management control device 3 used to implement the functions of the elevator system 100 according to this embodiment will be described. Figure 3 This is a block diagram illustrating an example of the hardware structure of the elevator control device 2 and the group management control device 3.

[0062] Computer 200 is the hardware used as a so-called computer. Computer 200 includes a CPU (Central Processing Unit) 201, ROM (Read Only Memory) 202, and RAM (Random Access Memory) 203, all connected to bus B. Furthermore, computer 200 includes non-volatile memory 204 and a network interface 205.

[0063] CPU 201 reads the program code of the software implementing the various functions involved in this embodiment from ROM 202 and executes it. Alternatively, computer 200 may replace CPU 201 by having a processing device such as MPU (Micro-Processing Unit). Variables, parameters, etc., generated during the computation process are temporarily written into RAM 203.

[0064] As a non-volatile storage device 204, it can use, for example, HDD (Hard Disk Drive), SSD (Solid State Drive), floppy disk, optical disk, magneto-optical disk, CD-ROM, CD-R, non-volatile memory card, etc. In addition to the OS (Operating System) and various parameters, this non-volatile storage device 204 also records programs used to enable the computer 200 to function.

[0065] In addition, the program can also be stored in ROM 202. That is, non-volatile memory 204 or ROM 202 is used as an example of a computer-readable non-volatile recording medium that stores a program executed by a computer.

[0066] In the network interface 205, for example, a NIC (Network Interface Card) can be used to send and receive various data with external devices via a network such as a LAN or a communication line.

[0067] <Example 1>

[0068] Next, refer to Figure 4 The control method of the elevator system 100 in the car operation panel 114 according to Embodiment 1 of this embodiment will be described. Figure 4 This is a flowchart illustrating an example of the control processing steps of the elevator system 100 according to Embodiment 1 of this invention, performed on the in-car operation panel 114.

[0069] First, the elevator control device 2's in-car operation panel control unit 21 (refer to...) Figure 1 The system determines whether the switch cabinet 113 is unlocked (step S1). Furthermore, as in this embodiment, when the car operation panel 114 is composed of a touch panel, the car operation panel control unit 21 can also determine whether an operation has been input to the car operation panel 114, instead of determining whether the switch cabinet 113 is unlocked. In other words, the car operation panel control unit 21 can detect the unlocking of the switch cabinet 113 or the input of an operation to the car operation panel 114 composed of the touch panel as the open state of the switch cabinet 113.

[0070] If it is determined in step S1 that the switch cabinet 113 is not unlocked (if step S1 is determined to be no), the operation panel 114 inside the car remains off (step S2), and the process ends. That is, the operation panel control unit 21 inside the car does not illuminate the operation panel 114 inside the car, and the process ends. On the other hand, if it is determined that the switch cabinet 113 is unlocked (if step S1 is determined to be yes), the operation panel control unit 21 inside the car illuminates the operation panel 114 inside the car (step S3).

[0071] Next, the control panel 21 inside the car determines whether the dedicated switch 115 has been switched to the on position (step S4). When the dedicated switch 115 is on, the elevator 1 is controlled in a dedicated operation mode. If it is determined in step S4 that the dedicated switch 115 has not been switched to the on position (if step S4 determines no), the operation control unit 22 of the elevator control device 2 performs service to the elevator 1 that is newly registered as the destination floor or has already been registered as the destination floor (hereinafter also referred to as the registered destination floor) (step S5).

[0072] Next, the car-side control panel 21 determines whether the switch cabinet 113 is locked (step S6). If it is determined in step S6 that the switch cabinet 113 is not locked (if step S6 determines no), the car-side control panel 21 returns to step S4 and makes a determination. On the other hand, if it is determined in step S6 that the switch cabinet 113 is locked (if step S6 determines yes), the car-side control panel 21 turns off the car-side control panel 114 (step S7). In other words, the control by which the car-side control panel 21 links with the registration information of the destination floor registration device 5 in the waiting hall to illuminate the destination floor button on the car-side control panel 114 ends.

[0073] Furthermore, in step S6, the car-side control panel 21 can also detect that the inactivity time of the car-side control panel 114 has lasted for a given threshold time, instead of locking the switch cabinet 113. That is, the car-side control panel 21 can detect the locking of the switch cabinet 113 or the inactivity time of the car-side control panel 114 exceeding the given threshold time as the switch cabinet 113 being in the off state.

[0074] If, in step S4, it is determined that the dedicated switch 115 is turned on (if step S4 determines yes), the control panel 21 inside the car stops receiving new calls from the destination floor registration device 5 in the waiting hall and allocates them to the elevator 1 (step S8). Next, the operation control unit 22 of the elevator control device 2 (refer to...) Figure 1 The service to the existing registration destination layer is executed (step S9). Next, the in-car operation panel control unit 21 determines whether there is still an existing registration destination layer (step S10). If it is determined in step S10 that there is still an existing registration destination layer (if step S10 determines yes), the operation control unit 22 performs the processing of step S9. That is, the service to the existing registration destination layer is executed.

[0075] On the other hand, if it is determined in step S10 that there is no existing registered destination floor (if step S10 is determined to be no), the car operation panel control unit 21 determines whether a dedicated operation destination floor has been registered (step S11). That is, it determines whether a given floor has been set as a dedicated operation destination floor through operation of the car operation panel 114. If it is determined in step S10 that no dedicated operation destination floor has been registered (if step S11 is determined to be no), the car operation panel control unit 21 repeatedly performs the determination in step S11.

[0076] On the other hand, if it is determined in step S11 that a dedicated destination floor has been registered (if step S11 is determined to be yes), the operation control unit 22 of the elevator control device 2 executes the service of elevator 1 to the dedicated destination floor (step S12). Next, the car operation panel control unit 21 determines whether the dedicated switch 115 is closed (step S13). If it is determined in step S13 that the dedicated switch 115 is not closed (if step S13 is determined to be no), the car operation panel control unit 21 repeatedly performs the determination in step S13.

[0077] On the other hand, if it is determined in step S13 that the dedicated switch 115 is closed (if step S13 is determined to be yes), the elevator control device 2 restarts the allocation of new calls from the destination floor registration device 5 in the waiting hall to the elevator 1 (step S14). Next, the operation control unit 22 of the elevator control device 2 performs service to the elevator 1 to the new registered destination floor (step S15).

[0078] Next, the car-side control panel 21 determines whether the switch cabinet 113 is locked (step S16). If it is determined in step S16 that the switch cabinet 113 is not locked (if step S16 determines no), the car-side control panel 21 returns to step S15 and performs processing. On the other hand, if it is determined in step S16 that the switch cabinet 113 is locked (if step S16 determines yes), the car-side control panel 21 performs processing in step S7. That is, the car-side control panel 114 is turned off. After processing in step S7, the control processing of the car-side control panel by the elevator system 100 ends.

[0079] In Embodiment 1 described above, the lighting or extinguishing of the control panel 114 inside the car corresponds to the unlocking or locking of the switch cabinet 113, respectively. Alternatively, the lighting or extinguishing of the control panel 114 inside the car corresponds to a contact with the control panel 114 (which is composed of a touch panel) or a period of inactivity on the control panel 114 exceeding a given threshold time. Therefore, according to Embodiment 1, the destination floor button will not be lit in conjunction with the registration information of the destination floor registration device 5 in the waiting hall during the period when the switch cabinet 113 is closed. Therefore, since there is no situation where light leaks from the switch cabinet 113 even though the passenger inside the car 10 is not doing anything, it will not cause passengers any sense of incongruity or unease. In addition, since it is not necessary to reset sensors for this control, it is possible to prevent an increase in the number of components and manufacturing costs of the elevator 1.

[0080] Furthermore, in Embodiment 1 described above, since new calls from the waiting hall to the elevator car 10 are not registered while the dedicated switch 115 is open, it is possible to prevent the elevator car 10 from stopping in a waiting hall with existing calls during dedicated operation. Additionally, even when the dedicated switch 115 is open, if there are existing call registrations in the waiting hall, the elevator car 10 can be used to serve the registered destination floor, and dedicated operation can be performed after that service is performed. Therefore, according to Embodiment 1, it is possible to prevent the elevator 1 from stopping at a floor where calls have already been registered. Furthermore, according to Embodiment 1, since the service to the existing registered destination floor is performed before dedicated operation, it is possible to prevent passengers in the elevator car 10 from unnecessarily waiting due to dedicated operation being performed first.

[0081] Furthermore, in Embodiment 1 described above, when the dedicated switch 115 is closed, the allocation of new calls to the car 10 from the destination floor registration device 5 in the waiting hall resumes. Therefore, according to Embodiment 1, it is possible to prevent the load from being continuously concentrated on elevator 1 other than the elevator 1 on which the dedicated switch 115 has been operated.

[0082] Furthermore, when the car control panel 114 is configured as a standard control panel instead of a touch panel, the car control panel control unit 21 controls the lighting or extinguishing of the destination floor button on the car control panel 114 in conjunction with the unlocking or locking of the switchgear 113. Moreover, the destination floor button illuminated by the car control panel control unit 21 during the unlocking detection of the switchgear 113 is the destination floor button corresponding to the registered destination floor registered through the hall destination floor registration device 5.

[0083] <Example 2>

[0084] Next, refer to Figure 5 The following describes the control method of the elevator system 100 in car operation panel 114 according to Embodiment 2 of this embodiment. Figure 5 This is a flowchart illustrating an example of the control processing steps of the elevator system 100 according to Embodiment 2 of this invention, performed by the in-car operation panel 114.

[0085] First, the car control panel 21 of the elevator control device 2 determines whether the switch cabinet 113 is unlocked (step S21). If it is determined in step S21 that the switch cabinet 113 is not unlocked (if step S21 determines no), the car control panel 114 remains off (step S22), and the process ends. That is, the car control panel 21 does not illuminate the car control panel 114 and the process ends. On the other hand, if it is determined that the switch cabinet 113 is unlocked (if step S21 determines yes), the car control panel 21 illuminates the car control panel 114 (step S23).

[0086] Next, the control panel 21 inside the car determines whether the maintenance switch 116 has been switched to the on position (step S24). When the maintenance switch 116 is on, the elevator 1 is controlled in maintenance operation mode. If it is determined in step S24 that the maintenance switch 116 has not been switched to the on position (if step S24 determines no), the operation control unit 22 of the elevator control device 2 performs service to the elevator 1 to a new or existing registered destination floor (step S25).

[0087] Next, the car-side control panel 21 determines whether the switch cabinet 113 is locked (step S26). If it is determined in step S26 that the switch cabinet 113 is not locked (if step S26 determines no), the car-side control panel 21 returns to step S24 and makes a determination. On the other hand, if it is determined in step S26 that the switch cabinet 113 is locked (if step S26 determines yes), the car-side control panel 21 turns off the car-side control panel 114 (step S27), ending this process.

[0088] If it is determined in step S24 that the maintenance switch 116 is turned on (if step S24 determines yes), the car operation panel control unit 21 stops receiving new calls from the destination floor registration device 5 in the waiting hall and controls the allocation of the elevator 1 to that elevator (step S28). Next, the operation control unit 22 of the elevator control device 2 performs service to the existing registered destination floor (step S29).

[0089] Next, the control panel 21 inside the car determines whether there are any existing registered destination floors (step S30). If it is determined in step S30 that there are existing registered destination floors (if step S30 determines yes), the operation control unit 22 performs the processing in step S29. That is, it performs service to the existing registered destination floor.

[0090] On the other hand, if it is determined in step S30 that there are no existing registered destination floors (if step S30 determines no), the operation control unit 22 starts the maintenance operation of elevator 1 (step S31). Next, the car operation panel control unit 21 displays the maintenance operation button on the car operation panel 114 (step S32). By performing this control, since the maintenance operation button will not be displayed when providing service to an existing registered destination floor, it is possible to prevent accidental operation of the maintenance operation button by passengers.

[0091] Next, the car control panel 21 determines whether the maintenance switch 116 is closed (step S33). If it is determined in step S33 that the maintenance switch 116 is not closed (if step S33 determines no), the car control panel 21 repeatedly performs the determination in step S33.

[0092] On the other hand, if it is determined in step S33 that the maintenance switch 116 is closed (if step S33 is determined to be yes), the elevator control device 2 restarts the allocation of new calls from the waiting hall destination floor registration device 5 to the elevator 1 (step S34). Next, the operation control unit 22 of the elevator control device 2 performs service to the elevator 1 to the new registered destination floor (step S35).

[0093] Next, the car-side control panel 21 determines whether the switch cabinet 113 is locked (step S36). If it is determined in step S36 that the switch cabinet 113 is not locked (if step S36 determines no), the car-side control panel 21 returns to step S35 and performs processing. On the other hand, if it is determined in step S36 that the switch cabinet 113 is locked (if step S36 determines yes), the car-side control panel 21 performs processing in step S27. That is, the car-side control panel 114 is turned off. After processing in step S27, the control processing of the car-side control panel by the elevator system 100 ends.

[0094] In Embodiment 2 described above, the lighting or extinguishing of the control panel 114 inside the car is also correlated with the unlocking action of the switch cabinet 113 (or, the contact action with the control panel 114 inside the car, which is composed of a touch panel) or the locking action. Therefore, according to Embodiment 2, similar to Embodiment 1, since there will be no situation where light leaks from the switch cabinet 113 even though the passenger inside the car 10 is not doing anything, it will not cause passengers any sense of incongruity or unease.

[0095] Furthermore, in the above-described embodiment 2, since new calls from the waiting hall to the car 10 are not registered during the period when the maintenance switch 116 is turned on, it is possible to prevent the car 10 from stopping in the waiting hall where there are calls during maintenance operation.

[0096] Furthermore, even when maintenance switch 116 is turned on, the elevator car 10 will continue to serve the registered destination floor if there is already a call registration in the waiting hall. Therefore, according to Embodiment 2, it is possible to prevent the elevator 1 from stopping at a floor where a call has already been registered.

[0097] Furthermore, in Embodiment 2, the service for calling and registering in the existing elevator lobby is executed before the service for manually registered destination floors via the control panel 114 inside the elevator car. Therefore, according to Embodiment 2, it is possible to prevent the service for manually registered destination floors via the control panel 114 inside the elevator car from being executed before the manually registered destination floor, thereby causing inconvenience to passengers already in the elevator.

[0098] <Example 3>

[0099] Next, refer to Figure 6 The following describes the control method of the elevator system 100 in car operation panel 114 according to Embodiment 3 of this embodiment. Figure 6 This is a flowchart illustrating an example of the control processing steps of the elevator system 100 according to Embodiment 3 of this invention, performed on the in-car operation panel 114.

[0100] First, the car control panel 21 of the elevator control device 2 determines whether the switch cabinet 113 is unlocked (step S41). If it is determined in step S41 that the switch cabinet 113 is not unlocked (if step S41 determines no), the car control panel 114 remains off (step S42), and the process ends. That is, the car control panel 21 does not illuminate the car control panel 114 and the process ends. On the other hand, if it is determined that the switch cabinet 113 is unlocked (if step S41 determines yes), the car control panel 21 illuminates the car control panel 114 (step S43).

[0101] Next, the car operation panel control unit 21 determines whether the destination floor has been manually registered via the car operation panel 114 (step S44). If it is determined in step S44 that the destination floor has not been manually registered (if step S44 determines no), the car operation panel control unit 21 repeatedly performs the determination in step S44.

[0102] On the other hand, if it is determined in step S44 that the destination floor has been manually registered (if step S44 is determined to be yes), it is determined whether the manually registered destination floor is the same destination floor registered by the elevator lobby destination floor registration device 5 (step S45). That is, in step S45, for the destination floor manually registered via the car control panel 114, it is determined whether there is also a call registered from the elevator lobby.

[0103] If, in step S45, it is determined that the manually registered destination floor is the same as the registered destination floor of the waiting hall destination floor registration device 5 (if step S45 determines yes), the destination floor registration processing unit 31 performs a process to increase the allocation order of elevator calls to those manually registered for the destination floor (step S46). Through this process, calls from the waiting hall destination floor registration device 5 are preferentially allocated to elevator 1 (car 10) that has operated the car control panel 114.

[0104] On the other hand, if it is determined in step S45 that the manually registered destination floor is not the registered destination floor of the waiting hall destination floor registration device 5 (if step S45 determines otherwise), the destination floor registration processing unit 31 controls the allocation of the elevator 1 to the elevator by suspending the acceptance of new calls sent from the waiting hall destination floor registration device 5 (step S47). Next, the operation control unit 22 of the elevator control device 2 performs the service to the existing registered destination floor (step S48).

[0105] Next, the car control panel 21 determines whether there are any existing registered destination floors (step S49). If it is determined in step S49 that there are existing registered destination floors (if step S49 is determined to be yes), the operation control unit 22 performs the processing in step S48. That is, it performs service to an existing registered destination floor. On the other hand, if it is determined in step S49 that there are no existing registered destination floors (if step S49 is determined to be no), or after the processing in step S46, the operation control unit 22 performs service to elevator 1 for manually registered destination floors (step S50).

[0106] Next, the car-side control panel 21 determines whether the switchgear 113 is locked (step S51). If it is determined in step S51 that the switchgear 113 is not locked (if step S51 determines no), the car-side control panel 21 repeatedly performs the determination in step S51. On the other hand, if it is determined in step S51 that the switchgear 113 is locked (if step S51 determines yes), the car-side control panel 21 turns off the car-side control panel 114 (step S52). After the processing in step S52, the control processing of the car-side control panel by the elevator system 100 ends.

[0107] In Embodiment 3 described above, when the destination floor registered by the lobby destination floor registration device 5 matches the manually registered destination floor in the car operation panel 114, the call from the lobby destination floor registration device 5 is preferentially assigned to the elevator 1 (car 10) that has operated the car operation panel 114. By implementing this control, since the newly registered floor in the lobby is the same as the manually registered destination floor in the car operation panel 114, it will not be assigned to elevators other than those manually registered via the car operation panel 114. Therefore, duplicate calls are no longer generated within the elevator system 100 that performs group management control. In other words, according to Embodiment 3, it is possible to prevent a decrease in the operating efficiency of elevator 1 in the elevator system 100 due to the generation of duplicate calls.

[0108] Furthermore, in Embodiment 3 described above, the service for calling and registering in the existing elevator lobby is executed before the service for manually registering at the destination floor via the control panel 114 inside the elevator car. Therefore, according to Embodiment 3, similarly to Embodiment 2, it is possible to prevent the situation where the service for manually registered destination floors via the control panel 114 inside the elevator car is executed before the manually registered destination floor, thereby causing inconvenience to passengers already in the elevator.

[0109] Furthermore, in Embodiment 3 described above, if the manually registered floor on the car control panel 114 is inconsistent with the newly registered floor registered from the destination floor registration device 5 in the waiting hall, the elevator 1 that has been manually registered on the car control panel 114 will not be assigned a new registration floor. Therefore, according to Embodiment 3, it is possible to prevent a situation where the elevator 1 no longer provides service at the destination floor manually registered via the car control panel 114, regardless of how much time has passed.

[0110] <Example 4>

[0111] Next, refer to Figure 7 The following describes the control method of the elevator system 100 in car operation panel 114 according to Embodiment 4 of this embodiment. Figure 7 This is a flowchart illustrating an example of the control processing steps of the elevator system 100 according to Embodiment 4 of this invention, performed by the in-car operation panel 114.

[0112] First, the car control panel 21 of the elevator control device 2 determines whether the switch cabinet 113 is unlocked (step S61). If it is determined in step S61 that the switch cabinet 113 is not unlocked (if step S61 determines no), the car control panel 114 remains off (step S62), and the process ends. That is, the car control panel 21 does not illuminate the car control panel 114 and the process ends. On the other hand, if it is determined in step S61 that the switch cabinet 113 is unlocked (if step S61 determines yes), the car control panel 21 illuminates the car control panel 114 (step S63).

[0113] Next, the car operation panel control unit 21 determines whether the destination floor has been manually registered via the car operation panel 114 (step S64). If it is determined in step S64 that the destination floor has not been manually registered (if step S64 determines no), the car operation panel control unit 21 repeatedly performs the determination in step S64.

[0114] On the other hand, if it is determined in step S64 that the destination floor has been manually registered (if step S64 determines yes), the car operation panel control unit 21 determines whether an operation to cancel the registration of the already registered destination floor has been entered in the car operation panel 114 (step S65). The operation to cancel the registration of the already registered destination floor may include, for example, a long press on the destination floor or a double press.

[0115] If it is determined in step S65 that no cancellation operation has been entered, the car operation panel control unit 21 repeatedly performs the determination in step S65. On the other hand, if it is determined that a cancellation operation has been entered (if it is determined in step S65), the car operation panel control unit 21 determines whether the floor where the cancellation operation was entered is a manually registered floor of the car operation panel 114 (step S66).

[0116] If, in step S66, it is determined that the destination floor was not manually registered (if step S66 determines no), that is, if the destination floor was registered from the destination floor registration device 5 in the waiting hall, the car operation panel control unit 21 will invalidate the cancellation operation input and will not accept the input (step S68). Next, the car operation panel control unit 21 will control the corresponding destination floor button on the car operation panel 114, that is, the destination floor button where the cancellation operation was input, to flash (step S69).

[0117] By controlling this process via the in-car operation panel control unit 21, the operator who has cancelled a floor can be aware that cancellation for that floor is no longer possible. Furthermore, the notification to the operator is not limited to flashing the destination floor button; it can also be a notification from a speaker (not shown) inside the car 10, such as a buzzer or broadcast. After step S69, the control processing of the in-car operation panel 114 by the elevator system 100 ends.

[0118] If, in step S66, it is determined that the floor to which the cancellation operation was input is a manually registered floor (if step S66 determines yes), the car control panel 21 determines whether the floor to which the cancellation operation was input is also a registered floor (waiting hall registration floor) of the waiting hall destination floor registration device 5 (step S67). If, in step S67, it is determined that it is also a waiting hall registration floor (if step S67 determines yes), the processing after step S68 is performed. That is, if the manually registered floor is also a waiting hall registration floor, the cancellation operation input is invalidated, and the destination floor button is flashed.

[0119] On the other hand, if in step S67 it is determined that the floor to which the cancellation operation was input is not a waiting hall registration floor, that is, a floor registered only through manual operation of the car control panel 114 (if step S67 determines otherwise), the car control panel 21 performs the registration cancellation (step S70). After the processing of step S70, the control processing of the car control panel 114 by the elevator system 100 ends.

[0120] In Embodiment 4 described above, since the cancellation operation of the registration targeting the destination floor registered from the destination floor registration device 5 in the waiting hall is invalidated, the service of elevator 1 to the destination floor registered from the destination floor registration device 5 in the waiting hall can be reliably performed. Therefore, according to Embodiment 4, it is possible to prevent a situation where elevator 1 does not provide service to passengers who register their destination floor in the waiting hall and enter the car 10.

[0121] Furthermore, in the above-described embodiment 4, since cancellation operations for destination floors registered only via the in-car control panel 114 are accepted, the ease of use of the in-car control panel 114 is maintained.

[0122] Furthermore, in Embodiment 4 described above, when a cancellation operation input for a destination floor registered from the waiting hall destination floor registration device 5 is set to invalid, control is performed to make the corresponding destination floor button flash. Therefore, according to Embodiment 4, it is possible to prevent the operator performing the cancellation operation from feeling uneasy about the cancellation not taking effect.

[0123] <Example 5>

[0124] Next, refer to Figure 8 The following describes the control method of the elevator system 100 in car operation panel 114 according to Embodiment 5 of this embodiment. Figure 8 This is a flowchart illustrating an example of the control processing steps of the elevator system 100 according to Embodiment 5 of this invention, performed on the in-car operation panel 114.

[0125] First, the operation control unit 22 of the elevator control device 2 determines whether the car 10 has reached the destination floor manually registered via the operation panel 114 inside the car (manually registered destination floor) (step S81). If it is determined in step S81 that the car 10 has not reached the manually registered destination floor (if step S81 determines no), the operation control unit 22 repeatedly performs the determination in step S81.

[0126] Furthermore, in step S81, the operation control unit 22 may instead determine whether the operation mode should be switched to the normal operation mode, instead of determining whether the car 10 has reached the manually registered destination floor. The normal operation mode is the mode in which the car travels to the registered destination floor registered from the waiting hall destination floor registration device 5. The switching of the normal operation mode is performed, for example, by the operation control unit 22 when the dedicated switch 115 or the maintenance switch 116 is closed.

[0127] On the other hand, if it is determined in step S81 that elevator 1 has reached the manual registration floor (if step S81 determines yes), the car operation panel control unit 21 determines whether the open (unlocked) state of switch cabinet 113 has been detected (step S82). If it is determined in step S82 that the unlocking of switch cabinet 113 has not been detected (if step S82 determines no), the operation control unit 22 determines whether the door opening time has expired (step S83).

[0128] If it is determined in step S83 that the door opening time has not expired (if step S83 is determined to be no), the car operation panel control unit 21 repeatedly performs the determination in step S83. On the other hand, if it is determined in step S83 that the door opening time has expired (if step S83 is determined to be yes), the car operation panel control unit 21 executes the door closing (step S84), ending this process.

[0129] If, in step S82, it is determined that the switch cabinet 113 is in an open state (if step S82 determines yes), the operation control unit 22 sets the door opening time to a longer time than the normal door opening time (an example of the second door opening time) (step S85). By performing this control by the operation control unit 22, it is possible to prevent the door 101 (see reference 114) from being locked again during the door opening time period when the operator of the control panel 114 inside the car attempts to relock the switch cabinet 113. Figure 1 ( ) Close. Therefore, according to Embodiment 5, it is possible to prevent situations such as: the operator moving to a floor different from the floor they originally intended to descend from elevator 1; the operator unnecessarily pressing the open button 111 (see reference) to prevent such a situation from occurring. Figure 1 ).

[0130] In step S85, after setting a longer door opening time, the operation control unit 22 determines whether a passenger's alighting has been detected based on the detection result of a load sensor (not shown) installed in the car 10 (step S86). If it is determined in step S86 that no passenger alighting has been detected (if step S86 determines no), the operation control unit 22 determines whether the door opening time has expired (step S87). If it is determined in step S87 that the door opening time has not expired (if step S87 determines no), the operation control unit 22 returns to step S86 and continues the determination.

[0131] On the other hand, if it is determined in step S87 that the door opening time has expired (if step S87 is determined to be yes), the operation control unit 22 further extends the door opening time (step S88) and returns to step S86 for determination. If a passenger's alighting is detected in step S86 (if step S86 is determined to be yes), the operation control unit 22 determines whether a passenger's alighting has been detected based on the detection result of a door photoelectric device (not shown) installed in the car 10 (step S89). If it is determined in step S89 that no passenger's alighting has been detected (if step S89 is determined to be no), the processing after step S87 is performed.

[0132] On the other hand, if it is determined in step S89 that a passenger has been detected alighting (if step S89 determines yes), the operation control unit 22 notifies the passenger of the door closing operation via a speaker (not shown) inside the car 10 (step S90), and executes the door closing (step S84). After the processing of step S84, the control processing of the elevator system 100 on the car operation panel 114 ends.

[0133] In other words, in Embodiment 5, even if the door opening time set longer in step S85 has expired, the door opening time is further extended if no passenger disembarks based on the detection results of the load sensor and the door photoelectric device. Therefore, according to Embodiment 5, since closing the door is only performed when the passenger has reliably disembarked, it is possible to prevent the door 101 from closing while the operator is performing operations such as locking the control panel 114 inside the car.

[0134] Furthermore, in Embodiment 5, examples of passenger alighting detection based on the detection results of a load sensor and passenger alighting detection based on the detection results of a door photoelectric device were given, but the present invention is not limited to these. When the detection accuracy of the load sensor or the door photoelectric device is sufficient, passenger alighting can also be detected based on the detection results of either the load sensor or the door photoelectric device. With this configuration, it is possible to ensure the time when a passenger alights from the car 10 to lock the switch cabinet 113, and to shorten the standby time of the door 101 from when the passenger alights until it is actually closed.

[0135] Furthermore, in Embodiment 5, the closing of the door is announced (pre-announced) before it is actually closed. Therefore, since passengers are aware in advance that door 101 is closing, they can take appropriate action, such as pressing the open button 111, as needed. Thus, for example, in the event of a malfunction in the load sensor or door photoelectric device, or in the case of other passengers boarding the elevator car 10 at approximately the same time as the passenger's alighting, situations where the passenger comes into contact with the closing door 101 can be prevented.

[0136] Furthermore, the above-described embodiments are provided for the purpose of explaining the present invention in detail and are not necessarily limited to having all the structures described.

[0137] In addition, Figure 1 Control lines or information lines indicated by arrows or double arrows are those deemed necessary for illustration, and are not necessarily limited to showing all control lines or information lines on the product. It can also be assumed that almost all structures are interconnected.

[0138] Furthermore, the processing steps described in this specification for processing time series naturally include processing performed sequentially in the order described, but not necessarily in a time series manner, and also include processing performed in parallel or individually (e.g., parallel processing or target-based processing).

[0139] Furthermore, as long as the respective hardware components can send and receive information via a network, the structural elements of the elevator system according to the above-described embodiment of the present invention can be installed on any hardware component. Additionally, the processing implemented by a processing unit can be achieved by a single hardware component or by distributed processing based on multiple hardware components.
