Description

The present invention relates to a replacement work method for replacing a component of an elevator having a plurality of components, a signal conversion device used in the replacement work, and an elevator renewal method.

Conventionally, when renewing elevator equipment installed in multi-story buildings, the hoistway in which the elevator was installed is often reused, and all of the components that make up the elevator are updated. Specifically, the elevator cars and the drive mechanism that raises and lowers the cars will be updated.

Additionally, due to recent improvements in technology, elevators that are controlled using new technology have features and performance that are significantly superior to existing elevators. For this reason, when an elevator is renovated, the control panel that controls the drive mechanism is often updated as well. Along with the update of the control panel, the various wiring that connects the drive mechanism and other components to the control panel will also be updated.

As a related technology, in the past, the guide sleeve extending from the existing wiring opening into the hoistway was cut at the introduction section on the hoistway side, and a new protective sleeve was installed in place of the guide sleeve that remained after cutting. There is a technology that allows various types of wiring to be routed from the control panel to the hoistway without special drilling work by laying various new wiring in the hoistway through a wiring opening (for example, the following (See Patent Document 1.)

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an elevator renewal method, elevator replacement method, and signal conversion device according to the present invention will be described in detail below with reference to the accompanying drawings.

(Elevator configuration)
First, the configuration of an elevator that is a target of the replacement work method according to the embodiment of the present invention will be described. FIG. 1 is an explanatory diagram showing the configuration of an elevator in a replacement work method according to an embodiment of the present invention.

In FIG. 1, an elevator 100 that is a target of the replacement work method according to the embodiment of the present invention can be realized by, for example, a rope-type (traction-type) elevator. Elevator 100 is installed in a building such as a multi-story building, for example.

The elevator 100 includes a car (car) 101 that carries people and goods. One car 101 is provided for each elevator 100. The car 101 is provided in a hoistway (not shown) that passes through each floor of the building in the vertical direction, that is, in the direction in which the car 101 moves.

The hoistway is equipped with a guide rail (not shown) on the side surface that guides the elevator car 101 to its ascending and descending position. Further, the hoistway is provided with a shock absorber 102 at the bottom to soften the impact when the car 101 falls and collides with the bottom surface. The shock absorber 102 may be a spring-type shock absorber 102 that uses the elastic force of a spring to soften the impact, or may be an oil-filled shock absorber 102 that uses hydraulic resistance to soften the impact. The buffer 102 may also be provided on the ceiling of the hoistway.

The cage 101 is connected to one end of the rope 103. The rope 103 is suspended over a pulley (not shown) and a traction machine 104 in a hanging manner, and the other end is connected to a counterweight 105. The rope 103 can be specifically realized, for example, by a steel wire.

The hoist 104 in the rope elevator 100 is installed, for example, in a machine room provided at the top of the elevator 100. The hoist 104 can be provided at the top of the elevator 100 with or without a machine room. Alternatively, if the elevator 100 is of a type without a machine room, the hoist 104 may be provided at the bottom of the elevator 100.

The hoist 104 is controlled using, for example, an inverter, and is driven and controlled by a control panel 106 so as to stop rotating at the floor where the car 101 is stopped. In the rope-type elevator 100, the car 101 is raised and lowered using frictional force (traction) between the rope 103 and the pulley, which is generated by driving the hoist 104. The hoisting machine 104 is driven and controlled by a control panel 106 included in the elevator 100.

The hoist 104 includes an encoder (not shown), and the control panel 106 can determine the rotational speed and rotational position of the hoist 104 based on an output signal from the encoder. For example, an absolute encoder or an incremental encoder may be used as the encoder.

The elevator 100 also includes an electromagnetic brake 107, a governor machine 108, a limit switch 109, and the like. The electromagnetic brake 107 includes a coil, and is driven and controlled by the control panel 106 to stop the rotation of the hoist 104 using electromagnetic force generated by energizing the coil. The electromagnetic brake 107 can maintain the state in which the rotation of the hoist 104 is stopped.

The electromagnetic brake 107 stops the rotation of the hoist 104 when the supply of power is stopped due to a power outage or the like. Specifically, the electromagnetic brake 107 is a non-excitation-operated electromagnetic brake 107 that operates with the force of a spring to stop the rotation of the hoist 104 when the coil is de-energized, such as during a power outage. be able to.

The speed governor 108 detects excessive speed of the car 101. The governor 108 can be realized, for example, by a centrifugal governor including a governor rope 108a, a governor pulley 108b, a rotating weight (not shown), and the like. In such a speed governor 108, the governor rope 108a is interlocked with the operation of the car 101. Governor pulley 108b rotates in conjunction with the operation of governor rope 108a.

The rotating weight operates according to the rotational speed of the governor pulley 108b, that is, the magnitude of the centrifugal force caused by the rotation of the governor pulley 108b. Specifically, the rotating weight operates to open toward the outer circumference of the governor pulley 108b when the rotation speed of the governor pulley 108b is high, and closes toward the inner circumference of the governor pulley 108b when the rotation speed of the governor pulley 108b is slow. It works like this.

The limit switch 109 includes a switch lever (not shown) that switches between supplying and cutting off power to the hoist 104. The switch lever is positioned at a position where power is supplied to the hoisting machine 104 during normal times, and when it is energized by the rotating weight of the speed governor 108, it cuts off the power supply to the hoisting machine 104. Displace to position.

The rotating weight of the speed governor 108 is configured such that the switch lever is displaced to a position where the power supply to the hoist 104 is cut off when the elevator speed of the car 101 reaches a certain level or higher than the rated speed. , energize the switch lever. Thereby, when excessive speed occurs in the car 101, the operation of the hoist 104 can be stopped and the car 101 can be stopped.

Furthermore, the elevator 100 may be equipped with an emergency stop device. The emergency stop device forces the operation of the car 101 when the operation of the car 101 and the operation of the governor rope 108a are different, that is, when the car 101 is in operation even though the governor rope 108a is stopped. make it stop. Since the emergency stop device can be easily realized using various known techniques, a description thereof will be omitted.

The basket 101 includes a door 101a. The car 101 also includes a motor (not shown) that opens and closes the door 101a, a door opening/closing sensor (not shown) that detects the open/closed state of the door 101a, an operation panel 101b, and the like. The motor that opens and closes the door 101a is driven and controlled by the control panel 106 to open and close the door 101a.

The output of the door opening/closing sensor changes depending on whether the door 101a or the door 110a is open or closed depending on the state of the safety shoe located between the door 101a and the door 110a. The door opening/closing sensor can be realized by, for example, a microswitch or a photoelectric sensor. The door opening/closing sensor is connected to the control panel 106 via wiring, and the signal output from the door opening/closing sensor is input to the control panel 106 via the wiring.

Doors 110a are provided at positions (platforms) 110 corresponding to each floor in the hoistway. A door 110a provided at the landing 110 is locked with a device called an interlock (not shown). The interlock engages with the opening/closing mechanism of the door 101a of the car 101 and releases the lock only when the motor provided in the car 101 is driven with the elevator 100 arriving at a stopped floor. Thereby, only the door 110a provided at the landing 110 on the floor where the car 101 is located can be opened and closed in conjunction with each other.

Each platform 110 is provided with an operation panel 111 that includes a platform call button 111a, a display 111b that displays the floor on which the car 101 is located, and the like.

In FIG. 2, the operation panel 101b is provided on the inner wall of the car 101, near the door 101a of the car 101. The operation panel 101b includes operation buttons 201, including a destination floor button for specifying the destination floor of the car 101, a door opening/closing button for opening and closing the door 101a, and the like.

The operation panel 101b provided in the car 101 includes a control board for the operation panel 101b, and is connected to the control panel 106 via the control board for the operation panel 101b. Each time the control board for the operation panel 101b receives an input operation on the operation button 201 by a user of the elevator 100, it generates a call signal according to the input operation, and outputs the generated call signal to the control panel 106. .

Further, the control board for the operation panel 101b outputs a signal according to the output of the door opening/closing sensor to the control panel 106, for example.

The landing call button 111a included in each operation panel 111 is provided, for example, on the wall surface 301 near the door 110a. The display devices 111b that display the floor on which the car 101 is located are each provided, for example, on the wall surface 302 above the door 110a. For example, as shown in FIG. 3, the display 111b displays the floor where the car 101 is located as well as the floors where the car 101 can stop. The display 111b may display only the floor where the car 101 is located. The elevator 100 does not need to include the display 111b.

Similarly to the control board for the operation panel 101b, the control board 111c generates a call signal corresponding to the input operation each time it receives an input operation on the hall call button 111a by a user of the elevator 100, and outputs the generated call. A signal is output to the control panel 106.

In this embodiment, the constituent parts according to the present invention can be realized by, for example, each part that outputs a signal to the control panel 106, a so-called "upward signal", among the parts included in the elevator 100.

Specifically, the output terminal of the control panel 106 transmits a control down signal generated by the CPU of the control panel 106 to the hoisting machine 104, the electromagnetic brake 107, the door 101a of the car 101, and the door 110a of the landing 110. Outputs to motors that open and close.

The CPU of the control panel 106 controls a plurality of components included in the elevator 100 and is in charge of controlling the elevator 100 as a whole. The memory of the control panel 106 stores programs, data, etc. used to control a plurality of components included in the elevator 100. The CPU of the control panel 106 performs arithmetic processing using programs, data, etc. stored in the memory, based on, for example, an upstream signal input via an input terminal. Further, the CPU of the control panel 106 outputs, for example, a signal based on the result of the arithmetic processing to the corresponding component via the output terminal.

Specifically, the CPU of the control panel 106 opens and closes the hoisting machine 104, the electromagnetic brake 107, and the doors 101a and 105a based on, for example, an up signal (call signal) output from the control board for the operation panel 101b. A downlink signal for control is generated for each component such as a motor, and the generated downlink signal for control is output to each corresponding component. In addition, the CPU of the control panel 106 determines whether each component is operating normally based on upstream signals output from each component such as the hoisting machine 104 (encoder), brake sensor, and door opening/closing sensor. to judge. Further, the CPU of the control panel 106 outputs, for example, a control down signal including a floor signal indicating the floor on which the car 101 is located to the control board for the operation panel 101b, and on the operation panel 101b, The floor on which the car 101 is located and the direction of movement (whether it is ascending or descending) are displayed.

The communication I/F is connected to a management server computer via a network such as the Internet (both are not shown). The management server computer is installed in a remote location different from the location where the elevator 100 to be monitored is installed and away from the location where the elevator 100 is installed. The management server computer can be installed, for example, at a maintenance management company that maintains and manages the elevator 100.

The communication I/F transmits an alarm signal output from the CPU of the control panel 106 to the management server computer. The alarm signal is output from the CPU of the control panel 106, for example, when a fault is detected in the elevator 100, or when the operation mode of the elevator 100 changes.

Further, the communication I/F receives various instructions such as an instruction to execute a diagnostic operation transmitted from the management server computer, and outputs them to the CPU of the control panel 106. The diagnostic operation is to output a signal from the control panel 106 to each part of the elevator 100 to operate each part in a predetermined order, and to output a signal indicating whether each part has operated normally according to the output signal. This is realized by outputting from the control panel 106. For example, the management server computer 130 outputs an instruction to execute a diagnostic operation periodically (for example, every time the last day of the month arrives).

By connecting the control panel 106 and the management server computer via the Internet rather than a public voice network such as a telephone line via a communication I/F, telephone lines can be easily disconnected in the event of an emergency such as an earthquake or other natural disaster. It is possible to avoid a delay in grasping the situation of the elevator 100 due to this. Thereby, in a situation where the elevator 100 is remotely monitored using the management server computer, if a malfunction occurs in the operation of the elevator 100, prompt action can be taken.

The control panel 106 may further be connected to a public voice network via a communication I/F. Public voice networks include fixed telephone networks (public switched telephone networks) and mobile telephone networks. A public voice network is made up of multiple exchanges (not shown), including subscriber line exchanges that accommodate telephone lines, transit exchanges that bundle subscriber line exchanges, and gateway exchanges that connect to other carriers' telephone networks. . Since the public voice network is a well-known technology, a description thereof will be omitted.

By connecting the control panel 106 to a public voice network via a communication I/F, voice communication between the interphone terminal device 205 and the management center can be realized. In this case, specifically, the communication I/F can be realized by, for example, a PHS (Personal Handy-phone System) board.

In this case, the control panel 106 may perform data communication using a PHS board. That is, the PHS board may be used for voice communication as well as data communication. Since the installation location of the elevator 100 is fixed, by performing communication using PHS, it is possible to ensure the quality of communication and reduce the cost of communication. This makes it possible to achieve both data communication between the control panel 106 and the management server computer and voice communication between the intercom terminal device 205 and the management center at low cost.

Further, specifically, the output terminal 404 outputs, for example, an upstream signal outputted by each component, which is subjected to signal conversion processing by the CPU 402, to the new control panel 106'.

(Functional configuration of signal conversion device 400)
Next, the functional configuration of the signal conversion device 400 will be explained. FIG. 5 is a block diagram showing the functional configuration of signal conversion device 400. In FIG. 5, each function of the signal conversion device 400 is an input section 501 on the component side, an input section 502 on the new control panel 106' side, a signal conversion section 503, and an output section 504 on the new control panel 106' side. and an output unit 505 on the component side.

The input unit 501 on the component side receives input of uplink signals output from each component of the elevator 100 to the control panel 106 . The input unit 501 on the component side can be realized, for example, by a plurality of input terminals 401 (connection terminals) provided for each component. The input unit 502 on the new control panel 106' side receives the input of the down signal that the new control panel 106' outputs to each component of the elevator 100. The input section 502 on the new control panel 106' side can be realized, for example, by an input terminal 401 (connection terminal) provided corresponding to the new control panel 106'.

The signal conversion unit 503 converts the upstream signal received by the input unit 501 on the component side into another signal that has the same meaning as the upstream signal and can be understood by the new control panel 106'. Further, the signal conversion unit 503 converts the downlink signal received by the input unit 502 on the new control panel 106' side into a signal having the same meaning as the downlink signal, which is understood by each component to which the downlink signal is output. Convert it to another signal that can be used.

(Procedure for replacing control panel 106)
Next, the processing procedure of the replacement method according to the embodiment of the present invention will be explained. FIG. 6 is a flowchart showing the processing procedure of the replacement method according to the embodiment of the present invention. FIGS. 7A to 7D are explanatory diagrams showing an overview of the replacement process of the replacement method according to the embodiment of the present invention. A procedure for replacing the control panel 106 using the signal conversion device 400 will be described. FIG. 6 shows a procedure for replacing the control panel 106 using the signal conversion device 400. 7A to 7D outline the process of replacing the control panel 106 using the signal conversion device 400. 6 and FIGS. 7A to 7D show a replacement procedure when replacing the old control panel 106 with a new control panel 106'.

The new control panel 106' accepts input signals to the new control panel 106' and outputs signals based on the input signals. The new control panel 106' operates according to a program written in a programming language different from the program used by the control panel 106. The new control panel 106' is a machine language (machine language), that is, an electrical signal that can be expressed in binary values of "0" and "1", and a signal that is different from the signal that the control panel 106 can understand. to understand.

In addition, the new control panel 106' outputs a signal having the same meaning as the signal outputted by the control panel 106 to the plurality of components (components A to D) 700 controlled by the control panel 106. Outputs a signal different from the signal that the other parts understand. The new control panel 106' may output, to the plurality of components 700 controlled by the control panel 106, signals that can be understood by the components 700 in the same manner as the signals output by the control panel 106.

In FIG. 6, when replacing the control panel 106 using the signal conversion device 400, first disconnect the old control panel 106 and each component 700, which are connected as shown in FIG. 7A, and then The old control panel 106 is removed as shown in (step S601).

Next, as shown in FIG. 7C, the signal conversion device 400 is connected to the component 700 from which the old control panel 106 has been removed (step S602). The signal conversion device 400 can be attached to, for example, a wall of a hoistway. Then, as shown in FIG. 7D, the new control panel 106' is connected to the signal conversion device 400 connected to the configuration section 700 in step S602 (step S603). The new control panel 106' is installed near the control panel 106, for example.

Thereafter, an operation check is performed (step S604), and it is determined whether the elevator 100 operates normally (step S605). In step S604, for example, the operation of the new control panel 106' is confirmed based on the upstream signal input from each component 700 to the new control panel 106' via the signal conversion device 400. Specifically, for example, a destination floor button on the operation panel 101b of the car 101 is operated to check whether the car 101 will go up or down to the specified floor.

Further, in step S604, for example, the operation of each component 700 in accordance with the down signal input from the new control panel 106' via the signal conversion device 400 is confirmed. Specifically, for example, the user operates the operation panel 111 provided at the landing 110, generates a call to the corresponding floor in response to the operation, and checks whether the car 101 is moved to the corresponding floor. .

In step S605, based on the confirmation result in step S604, it is determined whether the new control panel 106' operates based on the upstream signal input from each component 700 to the new control panel 106' via the signal conversion device 400. The elevator 100 is determined to be operating normally based on the results of whether or not the component 700 of the elevator 100 operates and whether or not the elevator 100 operates according to the down signal input from the new control panel 106' via the signal conversion device 400. Determine whether or not it works.

In step S605, if the elevator 100 operates normally (step S605: Yes), the replacement work of the control panel 106 is ended. On the other hand, in step S605, if the elevator 100 does not operate normally (step S605: No), the connection is confirmed (step S606).

In step S606, for example, the connection state between the component 700 that did not operate and the new control panel 106' is confirmed in accordance with the signal output from the new control panel 106'. After adjusting the connection state between the relevant component 700 and the new control panel 106', it is repeatedly determined whether the elevator 100 operates normally until the elevator 100 operates normally (step S605). ).

(Procedure for replacing component 700)
Next, the processing procedure of the replacement method according to the embodiment of the present invention will be explained. FIG. 8 is a flowchart showing the processing procedure of the replacement method according to the embodiment of the present invention. 9A to 9D are explanatory diagrams showing an overview of the replacement process of the replacement method according to the embodiment of the present invention. A procedure for replacing the component 700 using the signal conversion device 400 will be described. FIG. 8 shows a procedure for replacing the component 700. 9A to 9D, an overview of the replacement process of the component 700 is shown. In FIG. 8 and FIGS. 9A to 9D, the component (old component) 700 controlled via the signal conversion device 400 by the new control panel 106' replaced as described above is replaced with the new component 700'. It shows the replacement procedure when replacing.

In FIG. 8, when replacing the component 700, first, as shown in FIG. 9A, the connection between the signal conversion device 400 and the old component 700 is disconnected (step S801), and as shown in FIG. 9B, the new control A new component 700' replacing the removed old component 700 is connected to the panel 106' (step S802). Thereby, the old component 700 can be replaced with the new component 700'.

When replacing a plurality of old configuration units 700 with new configuration units 700′, in step S802, as shown in FIG. 9C, for each configuration unit 700 to be replaced, the corresponding old configuration unit 700 is replaced with the signal conversion device 400. A new component 700' replacing the removed old component 700 is connected to the new control panel 106'.

When all the old components 700 are replaced with new components 700', all the new components 700' are directly connected to the new control panel 106', and the new control panel 106' and the new components Direct signal exchange is performed with 700'. Accordingly, after all the old components 700 are replaced with new components 700', the signal conversion device 400 may be removed. The removed signal conversion device 400 can be reused for renewal of another elevator 100.

Next, the operation of the elevator 100 in which the old component 700 has been replaced with the new component 700' is checked (step S803), and it is determined whether the elevator 100 operates normally (step S804). In step S803, for example, a signal is output from the new control panel 106' to each component 700, and it is checked whether each component 700 operates according to the output signal. Alternatively, in step S803, only the operation of the replaced new component 700' may be checked.

Further, in step S803, for example, based on the signals output from each component 700, it is confirmed whether the new control panel 106' operates. Specifically, for example, a destination floor button on the operation panel 101b of the car 101 is operated to check whether the car 101 will go up or down to the specified floor.

In step S805, based on the confirmation result in step S804, whether or not the elevator 100 operates normally is determined based on whether all the components 700 have operated in accordance with the signals output from the new control panel 106'. to judge.

In step S805, if the elevator 100 operates normally (step S804: Yes), the replacement work of replacing the component part 700 with the new component part 700' is completed. On the other hand, in step S804, if the elevator 100 does not operate normally (step S804: No), the connection is confirmed (step S805).

In step S805, for example, the connection state between the component 700 that did not operate and the new control panel 106' is confirmed in accordance with the signal output from the new control panel 106'. After adjusting the connection state between the relevant component 700 and the new control panel 106', the elevator 10
It is repeatedly determined whether the elevator 100 operates normally until the elevator 100 operates normally (step S805).

In this way, when replacing the component 700 with the new component 700', by connecting the signal conversion device 400 between each component 700 and the new control panel 106', the control panel 106 can be controlled. Even when replacing with a new control panel 106' that operates according to a program written in a programming language different from the program used by the panel 106, the new control panel 106' can understand the signals output by the component 700. .

Also, when replacing the control panel 106 with a new control panel 106' that operates according to a program written in a programming language different from the program used by the control panel 106, the signals output by the new control panel 106' are configured. 700 can be understood and operated correctly.

Maintenance management of the elevator 100 can be carried out by, for example, periodically checking the operation history of the elevator 100 to be maintained or managing the operation history based on the communication results between the control panel 106 of the elevator 100 and an inspection terminal. This is achieved by replacing parts based on the following. Furthermore, maintenance management of the elevator 100 is realized, for example, by periodically communicating between the control panel 106 and the management server computer, executing diagnostic operations, and replacing parts according to the results of the diagnostic operations. .

In the maintenance management of such an elevator 100, for example, in the elevator 100 in which each component 700 is controlled by a dedicated ASIC, when it is desired to replace some components 700 with a new component 700', the new component 700 is controlled by a dedicated ASIC. It is assumed that the component 700' cannot be controlled by an existing ASIC. In such a situation, the new component 700' is limited to one that can be controlled by the existing ASIC.

More specifically, for example, in the elevator 100 where each component 700 is controlled by a dedicated ASIC, when replacing the hoisting machine, the power consumption is lower than that of the existing component (the hoisting machine) 700. Even if another hoisting machine with lower power and higher output exists, it is not possible to replace it with another hoisting machine due to limitations imposed by the existing ASIC. For this reason, those responsible for managing the elevator 100 are forced to choose between replacing the hoist with a hoisting machine that can be controlled by the existing ASIC, or renovating the elevator to include the existing ASIC. There was a situation where the degree of freedom in maintenance management by the 100 management managers was low.

In addition, communication between the control panel 106 and a terminal for inspection related to maintenance management of the elevator 100, or communication between the control panel 106 and the management server computer, uses signals specific to each manufacturer (manufacturer) of the elevator 100. The current situation is that there are many communications being carried out. For this reason, the current situation is that it is difficult for an independent elevator 100 maintenance service company that is independent of the manufacturer and the elevator management company affiliated with the manufacturer (hereinafter referred to as "manufacturer, etc.") to perform maintenance management.

In the current situation where communication is performed using signals unique to each manufacturer when maintaining and managing the elevator 100, the new component 700' that replaces the component 700 can be selected within the range specified by the manufacturer of each elevator 100. Unavoidably, there was a situation in which the person in charge of managing the elevator 100 and others had little freedom in maintenance management.

In addition, in the current situation where communication is performed using signals unique to each manufacturer, it is easy for the manufacturer of each elevator 100 to uniquely set the cost (maintenance management cost) required for maintenance management of the elevator 100. There was a situation in which it was difficult to reduce the maintenance and management costs borne by managers and others.

The safety and sense of security of the users of the elevator 100 tend to increase as the frequency of maintenance and inspection of the elevator 100 increases. On the other hand, in order to reduce maintenance and management costs in the above situation, it is possible to reduce the maintenance and management costs by reducing the frequency of maintenance inspections to the minimum level stipulated by the guidelines of the Ministry of Land, Infrastructure, Transport and Tourism or close to it. It becomes difficult to achieve both a reduction in the amount of noise and an improvement in the safety of users of the elevator 100.

On the other hand, according to the replacement work method of this embodiment, as described above, the replacement from the control panel 106 to the new control panel 106' is performed prior to replacing the component part 700 to the new component part 700'. Previously, by connecting the signal conversion device 400 between the new control panel 106' and the component section 700, it is possible to operate the elevator 100 even when the component section 700 and the new component section 700' coexist. Can be done. Thereby, the replacement work from the component part 700 to the new component part 700' can be performed in a distributed manner for each component part 700, and the elevator 100 can be operated between each replacement work.

In the embodiment described above, the elevator 100 was described in which each component 700 is controlled by executing various processes such as signal conversion processing using the CPU, but the control of the elevator 100 is realized using the CPU. Not limited to things. Instead with the CPU, for example, the ASIC (ASIC (APPLICICATION SPECIFIC INTEGRATED CIRCUIT), which is a specific integrated circuit for specific applications that collects multiple circuits, FPGA (FIELD -PROG (FIELD -PROG RAMMABLE GATE ARRAY ) etc. may be used to realize control of the elevator 100.

In addition, in the embodiment mentioned above, the rope-type elevator 100 was described, but the elevator 100 according to the present invention is not limited to the rope-type elevator 100. Instead of or in addition to the rope elevator 100, a hydraulic elevator 100 may be used, for example.

Further, in the above-described embodiment, a replacement construction method was described when replacing the control panel 106 equipped with a communication function with a new control panel 106', but the control panel 106 is not limited to one equipped with a communication function. . For example, even if the control panel 106 is not equipped with a communication function because remote monitoring was not assumed at the time of installation, and a separate communication device is connected after installation, the control panel 106 is replaced with a new control panel 106'. The replacement work method according to this invention can be applied. In this case, for example, the control panel 106 and the communication device are replaced with a new control panel 106'.

As explained above, when replacing the control panel 106 with a new control panel 106', the replacement construction method according to the embodiment of the present invention replaces the signal output by the component 700 with a signal having the same meaning as the signal. A signal conversion device 400 that converts into another signal that can be understood by the new control panel 106' is connected between the new control panel 106' and the components 700, and then at least one of the components 700 is A feature is that the new control panel 106' is replaced with a new component 700' that outputs a signal that can be understood.

According to the replacement construction method of the embodiment of the present invention, the signal conversion device 400 is connected between the new control panel 106' and the component 700 before replacing the control panel 106 with the new control panel 106'. Accordingly, the signal output by the configuration unit 700 can be converted by the signal conversion device 400 into another signal that the new control panel 106' can understand, and can be input to the new control panel 106'. As a result, even if the component 700 and the new component 700' coexist, the new control panel 1
06' can be operated.

Further, in the replacement work method according to the embodiment of the present invention, when replacing the control panel 106 with a new control panel 106', the signal output by the new control panel 106' is not changed to a signal having the same meaning as the signal. Then, a signal conversion device 400 that converts into another signal that can be understood by the component 700 is connected between the new control panel 106' and the component 700, and then at least one of the components 700 is connected to the new control panel 106. It is characterized in that it is replaced with a new component 700' that can understand the signals output by '.

According to the replacement construction method of the embodiment of the present invention, the signal conversion device 400 is connected between the new control panel 106' and the component 700 before replacing the control panel 106 with the new control panel 106'. Accordingly, the signal output by the new control panel 106' can be converted by the signal conversion device 400 into another signal that the component 700 can understand and input to the component 700. Thereby, the new control panel 106' can control the component 700, and the elevator 100 can be operated even when the component 700 and the new component 700' coexist.

Thereby, the replacement of the component part 700 with the new component part 700' can be performed multiple times (multiple days) during times when the elevator 100 is used less frequently, such as at night. Therefore, even if the renovation work takes several days from start to completion, the elevator can be renewed without causing any inconvenience to elevator users.

Further, according to the replacement construction method of the embodiment of the present invention, the component part 700 and the new component part 700' coexist, that is, only a part of the component part 700 is replaced with the new component part 700'. The elevator 100 can be operated even in this state. As a result, even after the control panel 106 is replaced with a new control panel 106', the usable components 700 can continue to be used without being replaced.

In this way, by selectively replacing only the components 700 that need to be updated, it becomes easier to plan and manage maintenance costs required for maintenance management of the elevator 100. As a result, it becomes possible to increase the frequency of replacement of specific components 700, such as the component 700 related to safety, and it is possible to improve the safety of users of the elevator 100.

Further, according to the replacement work method of the embodiment of the present invention, the elevator can be replaced without being influenced by the compatibility between the control panel 106 and the new component 700' or the new control panel 106' and the component 700. Renewal can be done in a distributed manner. This allows an independent maintenance management company to perform maintenance and management equivalent to that of a manufacturer without being influenced by the manufacturer of the elevator 100, without causing any inconvenience to elevator users.

In addition, the person in charge of managing the elevator 100 may not be limited to the manufacturer, but may have a company selected from a plurality of companies such as independent maintenance management companies and manufacturers maintain and manage the elevator 100. 100% safety can be ensured. In this way, by making it possible for an independent maintenance management company to perform maintenance management equivalent to that of a manufacturer, etc., the safety of the elevator 100 is ensured, and the maintenance management of the elevator 100 is monopolized by the manufacturer. It is possible to reduce the expenses (maintenance and management costs) required to perform the same maintenance and management as compared to the case of the above.
