[0016] The car operating panel 10 is a device that accepts car call operations by users. For example, the car operating panel 10 is provided inside the car 6, adjacent to the car door. For example, the car operating panel 10 is equipped with car equipment. For example, the car equipment is an alarm device. For example, the alarm device is a lighting device that lights up when the car operating panel 10 is operated. For example, the alarm device is an audio device that sounds an audio signal when the car operating panel 10 is operated. For example, the car equipment is an emergency call device. The emergency call device is a device that notifies by voice call in the event of an emergency. For example, the emergency call device is an emergency call button and an intercom.

[0017] The control device 11 is provided in the machine room 2. The control device 11 is electrically connected to devices such as the hoisting machine 4, the car operating panel 10, and the hall operating panel 8. The control device 11 is provided so as to be able to control the elevator as a whole.

[0018] The control device 11 receives information from each of the plurality of hall operating panels 8. The control device 11 dispatches a car 6 to each of the plurality of halls 3 based on the information received from each of the plurality of hall operating panels 8.

[0019] The control device 11 controls the operation of the plurality of hall devices 9 based on the traveling status of the car 6. For example, the control device 11 causes the hall devices 9 installed at the hall 3 where the car 6 arrives to notify users of the arrival of the car 6.

[0020] The control device 11 receives information from the car operating panel 10. The control device 11 controls the running of the car 6 based on the information received from the car operating panel 10.

[0021] The control device 11 includes a setting data storage unit 12, a transfer data storage unit 13, and an instruction unit 17. The setting data storage unit 12 stores data referenced by software programs. In the case of settings at the time of shipment of the control device 11, the setting data storage unit 12 stores data related to specification settings for the initial stage of elevator renovation work in correspondence with addresses.

[0022] The transfer data storage unit 13 is provided in a dummy area that is not referenced by the software program. The transfer data storage unit 13 includes a second-stage data storage unit 14, a third-stage data storage unit 15, and a restoration data storage unit 16.

[0024] The third stage data storage unit 15 stores data to be transferred in accordance with the specification setting of the third stage of the elevator renovation work and data indicating the transfer destination address.

[0025] The recovery data storage unit 16 stores the initial stage of the elevator repair work in association with the address. The recovery data storage unit 16 also stores the data that was stored in the setting data storage unit 12 immediately before it was overwritten in association with the address.

[0026] When elevator specifications are partially changed due to elevator renovation, the instruction unit 17 overwrites and stores data in the setting data storage unit 12 in accordance with the changes. For example, the instruction unit 17 overwrites and stores data corresponding to the transfer destination address stored in the transfer data storage unit 13 in the setting data storage unit 12. For example, the instruction unit 17 is provided so as to be operable by externally operating a switch or the like on a circuit board. For example, the instruction unit 17 is provided so as to be connected to and operable on an external device such as a portable switch.

[0027] Next, using Figures 2 to 4, we will explain how to change the elevator specification settings for each elevator renovation stage. FIG. 2 is a diagram showing the data configuration at the initial stage of the setting data storage unit 12 and the recovery data storage unit of the elevator control device 11 in the first embodiment.

[0028] As shown in Fig. 2, the setting data storage unit 12 and the transfer data storage unit 13 store multiple pieces of data. When the elevator renovation work is in the initial stage, the setting data storage unit 12 stores data for when the elevator specification settings are in the initial stage in association with addresses. Specifically, the setting data storage unit 12 stores data "01" in address "0000", data "02" in address "0001", and data "03" in address "0003".

[0029] When the elevator renovation work is in the early stages, the setting data storage unit 12 causes the software program to read out the data "01" at address "0000," the data "02" at address "0001," and the data "03" at address "0003" stored therein as elevator specification settings.

[0030] The second stage data storage unit 14 stores, in the first to third upper stages, data and corresponding addresses to be transferred to the setting data storage unit 12 when the elevator specification setting is set to the second stage.

[0031] The second-stage data storage unit 14 stores destination addresses corresponding to the data to be transferred in the second stage in the first and second upper stages. Specifically, the second-stage data storage unit 14 stores data "00" at address "1000" in the first upper stage. The second-stage data storage unit 14 stores data "00" at address "1001" in the second upper stage. In this case, the destination address is "0000", which is a combination of the data in the first and second upper stages of the second-stage data storage unit 14.

[0032] The second-stage data storage unit 14 stores data to be overwritten on the destination address to be transferred in the second stage at address "1002" in the third row from the top. Specifically, "02" is stored as the corresponding data at address "1002" in the third row from the top of the second-stage data storage unit 14.

[0033] The third stage data storage unit 15 stores, in the first to third upper stages, data and corresponding addresses to be transferred to the setting data storage unit 12 when the elevator specification setting reaches the third stage.

[0034] The third stage data storage unit 15 stores destination addresses corresponding to the data to be transferred in the third stage in the first and second upper stages. Specifically, the third stage data storage unit 15 stores data "00" at address "1100" in the first upper stage. The third stage data storage unit 15 stores data "01" at address "1101" in the second upper stage. In this case, the destination address is "0001", which is a combination of the data in the first and second upper stages of the third stage data storage unit 15.

[0035] The third-stage data storage unit 15 stores data to be overwritten on the destination address to be transferred in the third stage at address "1102" in the third stage from the top. Specifically, the third-stage data storage unit 15 stores data "03" at address "1102" in the third stage from the top.

[0036] Next, the configurations of the setting data storage unit 12 and the restoration data storage unit when the elevator renovation work has moved from the initial stage to the second stage will be described with reference to FIG. FIG. 3 is a diagram showing the second stage data configuration of the setting data storage unit 12 and the return data storage unit of the elevator control device according to the first embodiment.

[0037] When the elevator renovation work moves from the initial stage to the second stage, the instruction unit 17 (not shown) overwrites and stores the data stored in the second stage data storage unit 14 in the setting data storage unit 12. For example, the instruction unit 17, in response to an external operation, overwrites and stores the data stored in the second stage data storage unit 14 in the setting data storage unit 12. Specifically, the instruction unit 17 overwrites and stores the data "02" stored in the second stage data storage unit 14 at address "0000" in the setting data storage unit 12, which is the forwarding address. As a result, the data referenced in the software program is changed to the specification settings for the elevator renovation work being in the second stage.

[0038] At this time, the recovery data storage unit 16 stores the data for the elevator specification settings in the initial stage that was stored in the setting data storage unit 12 when the elevator renovation work was in the initial stage, and the corresponding address.

[0039] The recovery data storage unit 16 stores, in the first and second upper rows, destination addresses corresponding to the data stored in the setting data storage unit 12 at the initial stage. The recovery data storage unit 16 stores the data "00" at address "2000" in the first upper row. The recovery data storage unit 16 stores the data "00" at address "2001" in the second upper row. In this case, the combined "0000" of the first and second upper rows of the recovery data storage unit 16 is the address of the setting data storage unit 12 at the initial stage.

[0040] The recovery data storage unit 16 stores the data of the setting data storage unit 12 in the initial stage in the third row from the top. The recovery data storage unit 16 stores "01" as the data of the setting data storage unit 12 in the initial stage in the address "2002" in the third row from the top.

[0041] For example, when elevator renovation work moves from the initial stage to the second stage, the car operating panel 10 (not shown) is replaced. At this time, the data corresponding to address "0000" in the setting data storage unit 12 changes from "01" to "02," thereby changing the settings of the replaced car operating panel 10. For example, when the data corresponding to address "0000" in the setting data storage unit 12 changes from "01" to "02," the alarm device lights up in a lighting pattern appropriate for the alarm device of the new replaced car operating panel 10. For example, when the data corresponding to address "0000" in the setting data storage unit 12 changes from "01" to "02," the alarm device makes an announcement using a voice setting appropriate for the alarm device of the new replaced car operating panel 10.

[0042] Next, the configurations of the setting data storage unit 12 and the recovery data storage unit when the elevator renovation work moves from the second stage to the third stage will be explained using Fig. 4. Fig. 4 is a data configuration diagram of the third stage of the elevator control device in the first embodiment.

[0043] When the elevator renovation work moves from the second stage to the third stage, the instruction unit 17 (not shown) overwrites and stores the data stored in the third stage data storage unit 15 in the setting data storage unit 12. For example, the instruction unit 17, in response to an external operation, overwrites and stores the data stored in the third stage data storage unit 15 in the setting data storage unit 12. Specifically, the instruction unit 17 overwrites and stores the data "03" stored in the third stage data storage unit 15 at address "0001" in the setting data storage unit 12, which is the forwarding address. As a result, the data referenced in the software program is changed to the specification settings for when the elevator renovation work is in the third stage.

[0044] At this time, the recovery data storage unit 16 overwrites and stores the data for the elevator specification setting in the second stage stored in the setting data storage unit 12 when the elevator renovation work is in the second stage, and the corresponding address.

[0045] The recovery data storage unit 16 overwrites and stores in the first and second upper rows the transfer destination addresses corresponding to the data stored in the setting data storage unit 12 in the second stage. The recovery data storage unit 16 overwrites and stores the data "00" at address "2000" in the first upper row. The recovery data storage unit 16 overwrites and stores the data "01" at address "2001" in the second upper row. In this case, the combination of the first and second upper rows of the recovery data storage unit 16, "0001," is the address of the setting data storage unit 12 in the second stage.

[0046] The recovery data storage unit 16 overwrites and stores the data of the setting data storage unit 12 in the second stage in the third row from the top. The recovery data storage unit 16 overwrites and stores "02" as the data of the setting data storage unit 12 in the second stage in the address "2002" in the third row from the top.

[0047] For example, when elevator renovation work moves from the second stage to the third stage, the hall operating panel 8 (not shown) is replaced. At this time, the data corresponding to address "0001" in the setting data storage unit 12 changes from "02" to "03," thereby changing the settings of the replaced hall operating panel 8. For example, when the data corresponding to address "0001" in the setting data storage unit 12 changes from "02" to "03," the alarm device lights up in a lighting pattern suitable for the alarm device of the new replaced hall operating panel 8. For example, when the data corresponding to address "0001" in the setting data storage unit 12 changes from "02" to "03," the alarm device makes an announcement using a voice setting suitable for the alarm device of the new replaced hall operating panel 8.

[0048] Next, an example of the control device 11 will be described with reference to FIG. FIG. 5 is a hardware configuration diagram of the instruction unit of the elevator control device according to the first embodiment.

[0049] Each function of the control device 11 may be realized by a processing circuit. For example, the processing circuit may include at least one processor 100a and at least one memory 100b. For example, the processing circuit may include at least one dedicated hardware 200.

[0050] When the processing circuit includes at least one processor 100a and at least one memory 100b, the functions of the control device 11 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in the at least one memory 100b. The at least one processor 100a implements the functions of the control device 11 by reading and executing the program stored in the at least one memory 100b. The at least one processor 100a is also referred to as a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 100b may be a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD.

[0051] When the processing circuit includes at least one dedicated hardware 200, the processing circuit may be realized, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the instruction unit 17 may be realized by a processing circuit. For example, each function of the control device 11 may be realized collectively by a processing circuit.

[0052] Some of the functions of the instruction unit 17 may be realized by dedicated hardware 200, and the other functions may be realized by software or firmware. For example, some of the functions of the instruction unit 17 may be realized by a processing circuit as the dedicated hardware 200, and other functions of the instruction unit 17 may be realized by at least one processor 100a reading and executing a program stored in at least one memory 100b.

[0053] In this way, the processing circuitry implements the functions of the instruction unit 17 using hardware 200, software, firmware, or a combination thereof.

[0054] According to the first embodiment described above, the control device 11 replaces the data read by the software program at each stage of elevator specification change, which allows elevator renovation to be carried out in a simple manner.

[0055] Furthermore, the control device 11 changes the specification settings without using a computer owned by the maintenance company. Therefore, the specification settings of the elevator can be changed regardless of the number of employees who can use the computer or the number of computers. As a result, there is no need to dispatch a worker to the building where the elevator is installed to change the specification settings.

[0056] Furthermore, in the control device 11, workers cannot manually rewrite data by individually specifying addresses. This prevents incorrect specification settings. As a result, problems with elevator operation due to incorrect elevator specification settings do not occur. Furthermore, there is no need to reset the elevator specification settings. This prevents delays in the renovation work schedule.

[0057] Furthermore, the transfer data storage unit 13 stores the data in a dummy area, which prevents the data from being erroneously read out by a software program.

[0058] Furthermore, the transfer data storage unit 13 stores the data that was stored in the setting data storage unit 12 before it was overwritten. Therefore, if data in the setting data storage unit 12 is accidentally overwritten, the data in the setting data storage unit 12 can be restored to the state before it was overwritten.

[0059] Furthermore, the transfer data storage unit 13 stores a plurality of data items in association with addresses, which prevents data from being overwritten by mistake at a different address.

[0060] The instruction unit 17 is operated by receiving an input from the outside, and therefore can be operated by an operator from the control device 11.

[0061] The instruction unit 17 is connected to and operated by an external device, so that an operator can operate the control device 11 using the external device.

[0062] The transfer data storage unit 13 may include storage units for multiple stages in addition to the second-stage data storage unit 14 and the third-stage data storage unit 15. In this case, the storage units for multiple stages may have the same configuration as the second-stage data storage unit 14 and the third-stage data storage unit 15.

[0063] The instruction unit 17 may receive external input using a toggle switch. In this case, a three-position toggle switch with up, middle, and down positions may be used, and in the up position, data for advancing to the next stage may be overwritten, and in the down position, data for returning to the previous stage may be overwritten.

[0064] The elevator control device 11 of the first embodiment may be applied to an elevator that does not have a machine room 2 and has a hoisting machine 4, control device 11, and monitoring device installed at the top or bottom of the elevator shaft 1. [Explanation of symbols]
