Summary of the Invention

Problems to be Solved by the Invention

[0004] The inventor of the present application has found the following new problems when performing elevator renewal work in a divided manner. Specifically, when performing elevator renewal work, if the control device cannot recognize the model of the device replaced in the first renewal work constituted by the division, the control device cannot control the new device after replacement during normal operation after the first renewal work.

[0005] Therefore, it is necessary for maintenance workers or the like to rewrite the model code (control parameter) of the device stored in the storage unit of the control device to the device code of the new model using, for example, a maintenance computer or the like. However, this rewriting is difficult to perform quickly, and there is also a risk of incorrect rewriting.

[0006] Furthermore, such rewriting becomes complicated, especially when elevator renovation work is carried out in stages, with the control unit being replaced at the beginning of the work, and after the first stage of the renovation work, which is comprised of stages, the replaced equipment other than the control unit and the original equipment are mixed together.

[0007] Therefore, the purpose of this disclosure is to provide a method for carrying out elevator renovations in stages, and a system for using when carrying out elevator renovations in stages, which makes it easier to quickly and accurately recognize the model information of the equipment in the control device. [Means for solving the problem]

[0008] To solve the above problems, the method for carrying out elevator renewal in stages according to the present disclosure is a method for carrying out elevator renewal work in stages, comprising: a first equipment replacement step in which a new first equipment replaced from an existing first piece of equipment transmits first identification information that can identify the model of the new first equipment to a control device; an operation step in which, after interrupting the renewal work of the elevator midway and before the renewal work of the elevator is completed, the control device performs normal control to transport passengers into the elevator car based on the first identification information; and a second equipment replacement step in which, after the operation step, the renewal work is resumed, an existing second piece of equipment is replaced with a new second piece of equipment, and the new second equipment transmits second identification information that can identify the model of the new second equipment to the control device.

[0009] According to this disclosure, the replaced new first device transmits first identification information to the control device that allows it to identify itself. Therefore, compared to the case where a person uses a maintenance computer to rewrite the model information of the first device in the control device's memory with the model information of the new first device, the control device can more easily and quickly recognize the model of the new first device.

[0010] Alternatively, before replacing the existing first equipment with the new first equipment, the existing control device may be replaced with the new control device, a second equipment information code for identifying the model of the second equipment may be read by the identification information reader, and information based on the second equipment information code may be transmitted to the control device via the identification information reader, thereby allowing the control device to recognize the model of the existing second equipment, and in the operation step, the control device may transport passengers to the elevator car based on the information based on the second equipment information code.

[0011] If an existing control unit is initially replaced with a new control unit, and among the multiple existing devices in the elevator, there are devices that cannot transmit their own model information to the control unit, and furthermore, these devices are to be replaced during the renewal work but cannot be replaced during the first renewal work after the division, then the replacement control unit needs to recognize the model of these devices in order to operate the elevator normally after the first renewal work.

[0012] In this configuration, information based on the second equipment information code of the second equipment is sent to the control device via the identification information reader. Therefore, the control device can recognize the model of the second equipment, and the control device can smoothly start normal operation of the elevator after the initial renewal work.

[0013] Alternatively, before replacing the existing first equipment with the new first equipment, the existing control device may be replaced with a new control device, the elevator may be equipped with a third equipment, a first third equipment information code for identifying the model of the third equipment may be read by an identification information reader, and information based on the first third equipment information code may be transmitted to the control device via the identification information reader so that the control device recognizes the model of the existing third equipment, in the operation step the control device transports passengers in the elevator car based on the information based on the first third equipment information code, after the operation step the third equipment may be replaced with a new third equipment, a second third equipment information code for identifying the model of the new third equipment may be read by an identification information reader, and information based on the second third equipment information code may be transmitted to the control device via the identification information reader so that the control device recognizes the model of the new third equipment.

[0014] In some cases, the replaced equipment may not be able to transmit information to the control unit that allows it to recognize the model of the replaced equipment. With this configuration, even if the replaced equipment is a third-party device that cannot transmit information to the control unit that allows it to recognize the model of the replaced equipment, the control unit can still recognize the model of the third-party device.

[0015] Furthermore, the second device information code may be attached to the existing second device. Also, the first third device information code may be attached to the existing third device.

[0016] While the first sub-renewal work, which is divided into sections, does not involve replacement, once the renewal work is completed, for each of the one or more pieces of equipment that needs to be replaced, a device information code that identifies the model of the equipment, such as a QR code (registered trademark) or barcode, is attached to the equipment in advance by being affixed or otherwise attached, based on the serial number, model number, or manufacturing number inscribed on the equipment by engraving or affixing a sticker, etc. Also, for example, information linking the above device information code with the model is pre-stored in the memory of the control unit that was replaced first.

[0017] This configuration makes it easier to identify the location of the second device information code corresponding to the second device, and also makes it easier to identify the location of the first third device information code corresponding to the existing third device. Therefore, the second device information code and the first third device information code can be read quickly, making it easier to carry out construction work quickly.

[0018] Furthermore, the system used when carrying out the elevator renewal in stages according to this disclosure includes an information code for identifying the type of equipment included in the elevator, an identification information reader for reading the information code, and a control device that controls the drive of the elevator hoisting machine motor and is capable of identifying the type of equipment based on the information code from the identification information reader, before interrupting the elevator renewal work midway.

[0019] According to this disclosure, by reading the equipment's information code with an identification information reader, it becomes easier to mechanically resume normal elevator operation after the renovation work has been interrupted.

[0020] Furthermore, the system may include an information processing device that relays information from the identification information reading device to the control device.

[0021] According to this configuration, for example, an identification information reader that reads an information code can be easily electrically connected to the elevator's signal line via an information processing device (e.g., a maintenance computer).

[0022] Furthermore, the identification of the model by the control device may be performed before the elevator renovation work is interrupted, and after the renovation work resumes following the normal operation of the elevator, the new equipment installed after the removal of the equipment may transmit information to the control device that allows for the identification of the model of the new equipment.

[0023] This configuration makes it easier for the control device to quickly and accurately recognize the model of a new device. [Effects of the Invention]

[0024] According to the method and system for gradually renewing an elevator according to the present disclosure, when gradually renewing the elevator, it is easy to quickly and accurately make the control device recognize the model information of the equipment.

Brief Description of the Drawings

[0025] [Figure 1] It is a flowchart for explaining an example of the procedure of a method for gradually renewing an elevator according to an embodiment of the present disclosure. [Figure 2] It is a schematic configuration diagram of a system used when gradually renewing an elevator after the end of step S3. [Figure 3] It is a flowchart for explaining the procedure of step S8 in detail.

Mode for Carrying Out the Invention

[0026] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the elevator equipment may include one or more of a landing device, a car operation panel, a landing operation panel, a hoisting machine, a car door opening / closing device, and an announcement device. Also, when multiple embodiments, modification examples, etc. are included hereinafter, it is initially assumed that new embodiments can be constructed by appropriately combining their characteristic parts. Also, among the components described below, components not described in the independent claims indicating the most上位 concept are arbitrary components and not essential components.

[0027] Figure 1 is a flowchart illustrating an example of a procedure for a stepwise elevator renewal according to one embodiment of this disclosure. The elevator renewal work is divided into several sub-renewal works, and after each sub-renewal work is completed, the elevator is operated normally and passengers are transported by the car until the next sub-renewal work begins. Each sub-renewal work is carried out, for example, on at least one of the days and times when the elevator is used infrequently. The work schedule is determined in advance, and the date, time, and content of each sub-renewal work are determined in advance.

[0028] The procedure starts when the elevator mode is changed, for example, by operating the mode setting control unit installed inside the car, from the normal operation mode in which passengers are transported to a maintenance mode in which the raising and lowering of the car and the opening and closing of the car doors are controlled by an information processing unit (maintenance computer), or when the elevator operation is stopped from a normal operation state. In normal operation mode, the control device (control panel) controls the raising and lowering of the car (control of the hoisting motor) and the opening and closing of the car doors (control of the car door motor) based on the destination floor selection button, the car door opening button, the car door closing button installed inside the car, and the car call button installed at each floor landing. The landing doors are designed to open and close in conjunction with the car doors.

[0029] When the procedure starts, in step S1, one or more secondary pieces of equipment that will be replaced in the renewal work but not in the initial sub-renewal work are identified by a person (e.g., maintenance worker or installer) based on the schedule, etc. Furthermore, the model of each of the one or more secondary pieces of equipment is identified by a person based on identification information, such as serial number, model number, or manufacturing number, and a secondary equipment information code that can identify the model of the secondary equipment is attached to each of the one or more identified secondary pieces of equipment by means of an adhesive sticker or the like. Examples of secondary equipment information codes that may be attached include QR codes or barcodes.

[0030] In step S2, based on the schedule and other information, one or more third-party devices that will be replaced in the renewal work but not in the initial sub-renewal work are identified by a person. The difference between second-party and third-party devices will be explained later. Furthermore, each of the one or more third-party devices is identified by a person based on identification information, such as a serial number, model number, or manufacturing number, and a first third-party device information code that can identify the model of the third-party device is attached to each of the one or more identified third-party devices by means of a sticker or other means. Examples of the first third-party device information code that is attached include QR codes and barcodes.

[0031] The control device is preferably configured as a computer, such as a microcomputer, but in the next step S3, the elevator's control device is replaced. Figure 2 is a schematic diagram of the system 80 used when the elevator is refurbished in stages after the completion of step S3. Note that steps S1 to S3 can be performed in any order, and there may be times when steps can be performed simultaneously.

[0032] In Figure 2, the control device (control panel) 5 is a new control device after replacement, one or more first devices 10 are devices of elevator 1 that are replaced in the initial renewal work, and one or more second devices 30 and one or more third devices 50 are devices of elevator 1 that are not replaced in the initial sub-renewal work, as described above. As in this embodiment, elevator 1 may have one or more fourth devices 70 that are not replaced in this renewal work. Note that the procedures related to the fourth device 70 are omitted in Figure 1 and Figure 3 which will be explained below.

[0033] As shown in Figure 2, the control device 5 includes a control unit 6 and a storage unit 7. The control unit 6, i.e., the processor, includes, for example, a CPU (Central Processing Unit). The storage unit 7 is composed of a hard disk drive (HDD), semiconductor memory, etc., and the semiconductor memory is composed of non-volatile memory such as ROM (Read Only Memory) and volatile memory such as RAM (Random Access Memory). The storage unit 7 may consist of only one storage medium or may consist of multiple different storage mediums. The CPU reads and executes programs etc. that have been pre-stored in the storage unit. The non-volatile memory pre-stores control programs, predetermined thresholds etc. The volatile memory temporarily stores the read programs and processing data.

[0034] The memory unit 7 pre-stores information for each of the one or more second devices 30, linking the information based on the second device information code 30a with the model of the second device 30. The memory unit 7 also pre-stores information for each of the one or more third devices 50, linking the information based on the first third device information code 50a with the model of the third device 50.

[0035] Once step S3 is completed, in the following step S4, one or more first equipment 10s that are to be replaced in the initial sub-renewal work are replaced. There may be times when two or more first equipment 10s are replaced simultaneously. The newly replaced first equipment 10 transmits first identification information that identifies the model of the new first equipment 10 to the control device 5. As a result, the control device 5 becomes able to recognize the model of the new first equipment 10. In Figure 2, the information transmission path in step S4 is shown by a dotted arrow 75. In Figure 2, the destination of the information is shown to be an existing first equipment 10, but in reality, the destination of the information is a new first equipment that is not shown in Figure 2.

[0036] Step S4 can be performed at any time after the control device has been replaced with a new control device 5 and before the first sub-renewal work is completed. In Step S5, the identification information reading device 8, for example, a QR code reader or a barcode reader, is used to read the second equipment information code 30a that is attached to the second equipment 30 before replacement. After reading the second equipment information code 30a, the identification information reading device 8 is electrically connected to the signal line of the elevator 1 via, for example, an information processing device (maintenance computer) 9, and the information based on the read second equipment information code is transmitted from the identification information reading device 8 to the control device 5.

[0037] In Figure 2, the reading of the second device information code 30a by the identification information reading device 8 is indicated by a dashed-dotted arrow 85, the reading of the first third device information code 50a by the identification information reading device 8 (described below) is indicated by a dashed-dotted arrow 86, and the reading of the fourth device code 70a by the identification information reading device 8 (described below) is indicated by a dashed-dotted arrow 87.

[0038] In step S6, the identification information reader 8 is used to read the first third equipment information code attached to the third equipment before replacement. After reading the first third equipment information code, the identification information reader 8 is electrically connected to the signal line of the elevator 1 via, for example, an information processing device (maintenance computer) 9, and the information based on the read first third equipment information code is transmitted from the identification information reader 8 to the control device 5.

[0039] Steps S5 and S6 can be performed at any time after the control device has been replaced with a new control device 5 and before the first sub-renewal work is completed. Furthermore, with respect to one or more fourth devices 70 that are not replaced in this renewal work, as shown in Figure 2, each of the one or more fourth devices 70 may be identified by a person based on identification information, such as a serial number, model number, or manufacturing number, and each of the one or more fourth devices 70 whose model has been identified may be fitted with a fourth device information code 70a that can identify the model of the fourth device 70, such as by affixing.

[0040] The fourth device information code to be attached may be, for example, a QR code or a barcode. Furthermore, the storage unit 7 may pre-store information for each of the one or more fourth devices 70, linking the information based on the fourth device information code with the model of the fourth device 70. Alternatively, the identification information reader 8 may be used to read the fourth device information code attached to the fourth device 70.

[0041] The identification information reading device 8, after reading the fourth equipment information code, may be electrically connected to the signal line of the elevator 1 via, for example, an information processing device (maintenance computer) 9, to transmit information based on the read fourth equipment information code 70a from the identification information reading device 8 to the control device 5, thereby enabling the control device 5 to recognize the model of each fourth equipment 70. Alternatively, information on the models of one or more fourth equipment 70 may be pre-stored in the storage unit 7 of the replaced control device 5.

[0042] The control of equipment 10, 30, and 50 in the control device 5 varies depending on the model of equipment 10, 30, and 50. In step S7, after the renovation work is interrupted, the control device 5 performs normal control to transport passengers into the elevator car 1 based on the first identification information, the information based on the second equipment information code, and the information based on the first third equipment information code.

[0043] Step S7 is performed to shorten the continuous downtime of elevator 1 and improve user convenience by allowing elevator 1 to operate normally and transport passengers after the first sub-renovation work is completed and before the next sub-renovation work begins. As a result of the above operation, the new control device 5 recognizes the models of each piece of equipment 10, 30, 50, and 70 installed in elevator 1, so that normal operation of elevator 1 can be smoothly started after the first sub-renovation work.

[0044] In step S8, after the operation step, the remaining sub-renewal work and the normal operation of elevator 1 are repeated alternately until the renewal work is completed. Once step S8 is completed, the procedure is finished. Figure 3 is a flowchart that explains the procedure of step S8 in detail.

[0045] The procedure in step S8 first involves replacing one or more existing second devices 30 with new second devices in one or more sub-renewal projects in step S11, and then transmitting second identification information that identifies the model of the new second device to the control device 5.

[0046] A new second device can transmit second identification information to the control device 5 that identifies the model of the new second device, whereas a new third device cannot transmit identification information to the control device 5 that identifies the model of the new third device.

[0047] In step S12, in one or more sub-renewal work, the third equipment 50 is replaced with a new third equipment, and the second third equipment information code for identifying the model of the new third equipment is read by the identification information reader 8. Then, for example, information based on the second third equipment information code is transmitted to the control device 5 via the identification information reader 8 and the information processing device 9 so that the control device 5 can recognize the model of the new third equipment.

[0048] One or more sub-renewal work in step S12 may or may not be the same as one or more sub-renewal work in step S11. Steps S11 and S12 may be performed in either order, and there may be times when they are performed simultaneously. Once steps S11 and S12 are completed, the procedure in step S8 is completed.

[0049] The method for carrying out the renewal of elevator 1 in stages according to this disclosure is a method for carrying out the renewal work of elevator 1 in stages, and includes: a first equipment replacement step in which a new first equipment, which has been replaced from an existing first equipment 10, transmits first identification information to a control device 5 that allows the new first equipment to identify the model of the new first equipment; an operation step in which, after the renewal work of elevator 1 has been interrupted midway and before the renewal work of elevator 1 is completed, the control device 5 performs normal control to transport passengers into the elevator car of elevator 1 based on the first identification information; and a second equipment replacement step in which, after the operation step, the renewal work is resumed, the existing second equipment 30 is replaced with a new second equipment, and the new second equipment 30 transmits second identification information to the control device 5 that allows the new second equipment to identify the model of the new second equipment.

[0050] According to this disclosure, the replaced new first equipment transmits first identification information to the control device that allows it to identify itself. Therefore, compared to the conventional method, namely, a method in which a person uses a maintenance computer to chronologically rewrite the model codes (control parameters) of one or more first equipment in the memory of the control device to the model codes of one or more new first equipment, the control device 5 can more easily and quickly recognize the model of the new first equipment.

[0051] Alternatively, before replacing the existing first equipment 10 with a new first equipment, the existing control device may be replaced with a new control device 5, the second equipment information code 30a for identifying the model of the second equipment 30 may be read by the identification information reading device 8, and information based on the second equipment information code may be transmitted to the control device 5 via the identification information reading device 8, thereby allowing the control device 5 to recognize the model of the existing second equipment 30, and in the operation step, the control device may transport passengers to the elevator car 1 based on the information based on the second equipment information code.

[0052] If the existing control unit is initially replaced with a new control unit 5, and among the multiple existing pieces of equipment in elevator 1 are pieces of equipment 30 and 50 that cannot transmit their own model information to the control unit, and furthermore, if these pieces of equipment 30 and 50 cannot be replaced in the first renovation work after the division, then the replacement control unit 5 needs to recognize the models of these pieces of equipment 30 and 50 in order to operate elevator 1 normally after the first renovation work.

[0053] In this configuration, information based on the second equipment information code of the second equipment 30 is sent to the control device 5 via the identification information reader 8. Therefore, the control device 5 can recognize the model of the second equipment 30, and the control device 5 can quickly start normal operation of the elevator 1 after the initial renewal work.

[0054] Alternatively, before replacing the existing first equipment 10 with a new first equipment, the existing control device may be replaced with a new control device 5, and the elevator 1 may be equipped with a third equipment 50, and a first third equipment information code 50a for identifying the model of the third equipment may be read by the identification information reader 8, and information based on the first third equipment information code 50a may be transmitted to the control device 5 via the identification information reader 8, thereby allowing the control device 5 to recognize the model of the existing third equipment. Alternatively, during the operation step, the control device 5 may transport passengers into the elevator car of the elevator 1 based on information based on the first third equipment information code, and after the operation step, the third equipment 50 may be replaced with a new third equipment, and a second third equipment information code for identifying the model of the new third equipment may be read by the identification information reader 8, and information based on the second third equipment information code may be transmitted to the control device 5 via the identification information reader 8, thereby allowing the control device 5 to recognize the model of the new third equipment 50.

[0055] In some cases, the replaced equipment may not be able to transmit information to the control device 5 that allows the replacement equipment to be identified. However, with this configuration, even if the replaced equipment is a third-party device that cannot transmit information to the control device that allows the replacement equipment to be identified, the control device 5 can still recognize the model of the replaced third-party device.

[0056] Alternatively, the second device information code 30a may be attached to the existing second device 30. Furthermore, the first third device information code 50a may be attached to the existing third device 50.

[0057] For example, the memory unit 7 of the first replaced control device 5 stores in advance information linked to the equipment information codes 30a and 50a and the model. With this configuration, the installation location of the second equipment information code 30a corresponding to the second equipment 30 becomes easily recognizable, and the installation location of the first third equipment information code 50a corresponding to the existing third equipment 50 also becomes easily recognizable. Therefore, the reading of the second equipment information code 30a and the first third equipment information code 50a can be performed quickly, making it easier to carry out construction work quickly.

[0058] Furthermore, the system used when carrying out the phased renewal of elevator 1 according to this disclosure includes information codes 30a and 50a for identifying the models of equipment 30 and 50 included in elevator 1, an identification information reading device 8 for reading the information codes 30a and 50a, and a control device 5 that controls the drive of the hoisting machine motor of elevator 1 and is capable of identifying the models of equipment 30 and 50 based on the information codes 30a and 50a from the identification information reading device 8, before interrupting the renewal work of elevator 1.

[0059] According to this disclosure, by reading the equipment information codes 30a and 50a with the identification information reading device 8, it becomes easier to mechanically resume normal operation of elevator 1 after the renovation work has been interrupted.

[0060] Furthermore, the system may include an information processing device 9 that relays information from the identification information reading device 8 to the control device 5. The information processing device 9 may consist of a maintenance computer.

[0061] With this configuration, for example, the identification information reading device 8, which reads the information codes 30a and 50a, can be easily electrically connected to the signal line of the elevator 1 via the information processing device 9.

[0062] Furthermore, the control device 5 may identify the model of the second equipment 30 before the renovation work on elevator 1 is interrupted, and after the renovation work resumes following the normal operation of elevator 1, the new second equipment installed after the removal of the second equipment 30 may transmit information to the control device 5 that allows for the identification of the model of the new second equipment.

[0063] This configuration makes it easier for the control device to quickly and accurately recognize the model of a new device.

[0064] This disclosure is not limited to the embodiments and their variations, and various improvements and modifications are possible within the scope of the claims of this application and their equivalents.

[0065] For example, in the above embodiment, the control device 5 used the second device information code 30a to identify the model of the second device 30 before replacement. However, it is also possible that the second device before replacement receives a transmission command for identification information that can identify its model from the new control device after the control device has been replaced, and transmits the identification information to the new control device in response to that transmission command.

[0066] Furthermore, the case in which elevator 1 is equipped with a third device 50 and a fourth device 70 was described. However, the elevator does not have to have at least one of the third and fourth devices. Furthermore, the case in which information based on information codes 30a, 50a, and 70a is transmitted to the control device 5 via an identification information reader 8 and an information processing device (relay device) 9 was described. However, the information based on the information codes may be electrically connected to the elevator's signal line via the identification information reader but without going through the information processing device. Furthermore, the case in which information codes 30a, 50a, and 70a are attached to devices 30 and 50 was described. However, the information codes may be attached near the devices, etc., and do not have to be attached to the devices themselves. [Explanation of Symbols]
