Description

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

Conventionally, when renewing the equipment of an elevator installed in a multi-story building or the like, the hoistway where the elevator is installed is often reused and all the components constituting the elevator are updated. Specifically, the elevator car and the drive mechanism for raising and lowering the car will be updated.

In addition, due to recent technological improvements, elevators controlled using new technology have significantly superior functions and performance than existing elevators. For this reason, when the elevator is renewed, the control panel that controls the drive mechanism and the like is often updated. Along with the update of the control panel, various wirings connecting the components such as the drive mechanism and the control panel are also updated.

As a related technology, specifically, a guide sleeve extending from an existing wiring port into the hoistway is cut at an introduction portion on the hoistway side, and a new protective sleeve is installed in place of the guide sleeve remaining after cutting. There was a technology in which various new wires were laid in the hoistway through the wiring port so that the various wires could be passed from the control panel to the hoistway without any special drilling work (for example, the following). See Patent Document 1).

In addition, as a related technology, specifically, during the renewal work, the old group management device is removed, and the operation control of all elevators including the old elevator is performed only by the new group management device. There was a technology in which the old elevator was configured to send and receive signals to and from the new group management device via the old and new switching interface (see, for example, Patent Document 2 below). ).

Hereinafter, preferred embodiments of the signal conversion device and the replacement work method according to the present invention will be described in detail with reference to the accompanying drawings.

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

In FIG. 1, the elevator 100, which is the target of the replacement work method of the first embodiment according to the present invention, can be realized by, for example, a rope type (traction type) elevator. The elevator 100 is installed in a building such as a multi-story building. The elevator 100 shown in FIG. 1 operates independently. Therefore, it does not operate in conjunction with other elevators, and does not have a control unit (for example, the group management device 1001 of the second embodiment shown in FIG. 10) for operating in conjunction with other elevators. , Not even connected.

The elevator 100 includes only one basket (riding basket) 101 for carrying people and goods. One basket 101 is provided as a single unit, that is, in one elevator 100. The basket 101 is provided in one hoistway (not shown in FIG. 1) that penetrates each floor in the building along the vertical direction, that is, the moving direction of the basket 101.

As can be seen from FIG. 10 described later, since the elevator 100 that operates independently has one basket 101, there is also one hoistway (in FIG. 10, there are three elevators that operate independently (1). Units 100-1, 2 units 100-2, 3 units 100-3). In FIG. 1, since only one hoisting machine 104 and one rope 103 are drawn for each basket 101, the elevator according to the first embodiment is an elevator that operates independently, that is, This elevator is provided with only one basket, and has an elevator equipment configuration in one hoistway, such as a basket 101, a shock absorber 102, a rope 103, and a hoisting machine 104. That is, this is an elevator having a plurality of components consisting of only one hoistway. Further, the elevator 100 that operates independently here is composed of components controlled by a control panel 106, which will be described later, and does not include components outside the building such as a monitoring center.

The hoistway is provided with a guide rail (not shown) that guides the elevating position of the basket 101 on the side surface. Further, the hoistway is provided with a shock absorber 102 at the bottom, which cushions the impact when the basket 101 falls and collides with the bottom surface. The shock absorber 102 may be a spring-type shock absorber 102 that softens the impact by utilizing the elastic force of the spring, or may be an oil-filled shock absorber 102 that softens the shock by utilizing the hydraulic resistance. The shock absorber 102 may also be provided on the ceiling surface of the hoistway.

The basket 101 is connected to one end of the rope 103. The rope 103 is slidably hung on a pulley (not shown) and a hoisting machine (traction machine) 104, and the other end is connected to a counterweight 105. Specifically, the rope 103 can be realized by, for example, a steel wire.

The hoisting machine 104 in the rope-type elevator 100 is installed, for example, in a machine room provided at the top of the elevator 100. The hoisting machine 104 can be provided at the uppermost part of the elevator 100 regardless of the presence or absence of a machine room. Alternatively, when the elevator 100 is of a type without a machine room, the hoisting machine 104 may be provided at the lower part of the elevator 100.

The hoisting machine 104 is controlled by using, for example, an inverter, and is driven and controlled by the control panel 106 so as to stop the rotation on the floor where the basket 101 is stopped. In the rope type elevator 100, the basket 101 is moved up and down by utilizing the frictional force (traction) between the rope 103 and the pulley generated by driving the hoisting machine 104. The hoisting machine 104 is driven and controlled by a control panel 106 included in the elevator 100.

The hoisting machine 104 includes an encoder (not shown), and the control panel 106 can determine the rotation speed and the rotation position of the hoisting machine 104 based on the output signal from the encoder. As the encoder, for example, an absolute encoder may be used, or an incremental encoder may be used.

Further, the elevator 100 includes an electromagnetic brake 107, a speed governor (governor machine) 108, a limit switch 109, and the like. The electromagnetic brake 107 includes a coil, is driven and controlled by a control panel 106, and uses an electromagnetic force generated by energizing the coil to stop the rotation of the hoisting machine 104. The electromagnetic brake 107 can maintain the state in which the hoisting machine 104 has stopped rotating.

The electromagnetic brake 107 stops the rotation of the hoisting machine 104 when the power supply is stopped due to a power failure or the like. Specifically, the electromagnetic brake 107 uses a non-excitation actuated electromagnetic brake 107 that operates by the force of a spring to stop the rotation of the hoisting machine 104 when the energization of the coil is cut off, such as during a power failure. be able to.

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

The rotary weight operates according to the rotation 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 rotary weight operates so as to open toward the outer peripheral side of the governor pulley 108b when the rotation speed of the governor pulley 108b is high, and closes to the inner peripheral side of the governor pulley 108b when the rotation speed of the governor pulley 108b is slow. Works like this.

The limit switch 109 includes a switch lever (not shown) for switching power supply / cutoff to the hoisting machine 104. The switch lever is positioned at a position to supply power to the hoisting machine 104 in normal times, and cuts off the power supply to the hoisting machine 104 when urged by the rotary weight of the speed governor 108. Displace to position.

The rotary weight of the speed governor 108 is displaced so that the switch lever is displaced to a position where the power supply to the hoisting machine 104 is cut off when the ascending / descending speed of the basket 101 exceeds a certain speed with respect to the rated speed. To urge the switch lever. As a result, when the speed of the basket 101 is exceeded, the operation of the hoisting machine 104 can be stopped and the basket 101 can be stopped.

Further, the elevator 100 may be provided with an emergency stop device. The emergency stop device forcibly operates the basket 101 when the operation of the basket 101 and the operation of the governor rope 108a are different, that is, when the basket 101 is operating even though the governor rope 108a is stopped. Stop it. Since the emergency stop device can be easily realized by using various known techniques, the description thereof will be omitted.

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

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

Doors 110a are provided at positions (landings) 110 corresponding to each floor in the hoistway. The door 110a provided at the landing 110 is locked by a device called an interlock or the like (not shown). The interlock engages with the opening / closing mechanism of the door 101a of the basket 101 to release the lock only when the motor included in the basket 101 is driven while the elevator 100 has arrived at the stop floor. As a result, only the door 110a provided at the landing 110 on the floor where the basket 101 is located can be opened and closed in conjunction with each other.

Each landing 110 is provided with an operation panel 111 provided with a landing call button 111a, a display 111b for displaying the floor on which the basket 101 is located, and the like.

In FIG. 2, the operation panel 101b is a wall surface inside the basket 101 and is provided in the vicinity of the door 101a of the basket 101. The operation panel 101b includes an operation button 201 including a destination floor button for designating the destination floor of the basket 101, a door open / close button for supporting the opening / closing of the door 101a, and the like. Further, the operation panel 101b is provided with a display 202 that displays the floor or the like on which the basket 101 is located.

The operation panel 101b provided in the basket 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 for the operation button 201 by a user of the elevator 100 or the like, a call signal corresponding to the input operation is generated, and the generated call signal is output to the control panel 106. ..

Further, the control board for the operation panel 101b outputs, for example, a signal corresponding to the output of the door open / close sensor to the control panel 106. Further, the control board for the operation panel 101b controls the display 202 according to the signal output from the control panel 106, and displays the floor on which the basket 101 is located.

The display 111b may display only the floor on which the basket 101 is located. The elevator 100 does not have to include the display 111b.

Similar to the control board for the operation panel 101b, the control board 111c generates a call signal corresponding to the input operation every time the user of the elevator 100 or the like receives an input operation for the landing call button 111a, and the generated call. The signal is output to the control panel 106.

In the first 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, that is, a so-called "uplink signal" among the parts included in the elevator 100. Further, in the first embodiment, among the parts included in the elevator 100, for example, each part that operates according to a signal output from the CPU (Central Processing Unit) of the control panel 106, that is, a so-called "downlink signal", is used for the present invention.

Specifically, the input terminal of the control panel 106 receives, for example, the input of a call signal output from the control board for the operation panel 101b or the control board for the operation panel 101b. Further, the input terminal of the control panel 106 receives, for example, the input of a signal output from the encoder. Further, the input terminal of the control panel 106 receives input of signals output from various sensors such as a limit switch 109, a door open / close sensor, and a brake sensor whose output changes according to the operation of the electromagnetic brake 107. The brake sensor can be realized by, for example, a microswitch or a photoelectric sensor.

The output terminal of the control panel 106 is a hardware interface for connecting a plurality of components included in the elevator 100 and the CPU of the control panel 106, and a downlink signal output from the CPU of the control panel 106 is sent to the corresponding component unit. Output. Specifically, the output terminal of the control panel 106 uses, for example, the down signal for control generated by the CPU of the control panel 106 to the hoisting machine 104, the electromagnetic brake 107, the door 101a of the basket 101, and the door 110a of the landing 110. Output to the motor that opens and closes.

The CPU of the control panel 106 controls a plurality of components included in the elevator 100, and controls the entire elevator 100. The memory of the control panel 106 stores programs and data used for controlling a plurality of components included in the elevator 100. The CPU of the control panel 106, for example, performs arithmetic processing using a program or data stored in a memory based on an uplink signal input via an input terminal. Further, the CPU of the control panel 106 outputs, for example, a signal based on the result of arithmetic processing to the corresponding component unit 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 110a based on, for example, an uplink signal (call signal) output from the control board for the operation panel 101b. A control downlink signal is generated for each component such as a motor, and the generated control downlink signal is output to each corresponding component. Further, the CPU of the control panel 106 determines whether or not each component operates normally based on the uplink signals output from each component such as the hoisting machine 104 (encoder), the brake sensor, and the door open / close sensor. To judge. Further, the CPU of the control panel 106 outputs, for example, a down signal for control including a floor signal indicating the floor on which the basket 101 is located to the control board for the operation panel 101b, and the operation panel 101b displays the control board. The floor on which the basket 101 is located and the moving direction (whether it is rising or falling) are displayed.

The communication I / F is connected to the management server computer via a network such as the Internet (all of which are not shown). The management server computer is installed in a remote place away from the place where the elevator 100 to be monitored is installed, which is different from the place where the elevator 100 to be monitored is installed. The management server computer can be installed, for example, in a maintenance management company that is in charge of maintenance management of the elevator 100.

The communication I / F transmits a notification 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 failure 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 execution instruction of a diagnostic operation transmitted from the management server computer and outputs them to the CPU of the control panel 106. In the diagnostic operation, the control panel 106 causes each part of the elevator 100 to output a signal for operating each part in a predetermined order, and a signal indicating whether or not each part operates normally according to the output signal. Is realized by outputting from the control panel 106. The management server computer (not shown) outputs, for example, an execution instruction of 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 communication I / F via the Internet instead of the public voice network such as the telephone line, the telephone line is punctured in an emergency such as an earthquake or other natural disaster. It is possible to avoid delay in grasping the situation of the elevator 100 due to the above. As a result, in a situation where the elevator 100 is remotely monitored using the management server computer, it is possible to take a prompt response when a problem occurs in the operation of the elevator 100.

The control panel 106 may be further connected to the public voice network via the communication I / F. Public voice networks include fixed telephone networks (public switched telephone networks) and mobile telephone networks. The public voice network is composed of a plurality of exchanges (not shown), such as a subscriber line exchange for accommodating telephone lines, a relay exchange for bundling subscriber line exchanges, and a barrier exchange for connecting to the telephone networks of other operators. .. Since the public voice network is a known technique, the description thereof will be omitted.

By connecting the control panel 106 to the public voice network via the communication I / F, voice communication between the intercom 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) substrate.

In this case, the control panel 106 may perform data communication using the PHS board. That is, the PHS board may be used not only for voice communication but also for data communication. Since the installation location of the elevator 100 is fixed, it is possible to ensure the quality of communication and reduce the cost of communication by performing communication using PHS. As a result, 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 can be realized at low cost.

The CPU 402 controls each part of the signal conversion device 400, and controls the entire signal conversion device 400. The memory 403 stores programs, data, and the like used for signal processing. Specifically, the memory 403 stores, for example, a program or data related to a signal conversion process for converting an uplink signal into another signal that can be understood by the new control panel 106'.

Further, specifically, the memory 403 stores, for example, a program or data related to a signal conversion process for converting a downlink signal into another signal that can be understood by each component. The CPU 402 performs signal conversion processing on an uplink signal or a downlink signal input via the input terminal 401 by using a program or data stored in the memory 403.

The output terminal 404 is a connection terminal (hardware interface) for connecting a plurality of components included in the elevator 100, a new control panel 106', and a signal conversion device 400, and corresponds to a signal output from the CPU 402.

Specifically, the output terminal 404 outputs, for example, an uplink signal output by each component unit, which has been subjected to signal conversion processing by the CPU 402, to the new control panel 106'.

In particular, in the second embodiment described later, the communication I / F 405 is connected to, for example, a control panel 106 or another adjacent signal conversion device 400 to transmit / receive information.

FIG. 5 is a block diagram showing a functional configuration of the signal conversion device 400 according to the first embodiment of the present invention. In FIG. 5, each function of the signal conversion device 400 includes an input unit 501 on the component side, an input unit 502 on the new control panel 106'side, a signal conversion unit 503, and an output unit 504 on the new control panel 106'side. And the output unit 505 on the component side.

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

The signal conversion unit 503 converts the uplink signal received by the input unit 501 on the component unit side into another signal having the same meaning as the uplink signal and which can be understood by the new control panel 106'. Further, the signal conversion unit 503 has the same meaning as the downlink signal received by the input unit 502 on the new control panel 106'side, and is understood by each component unit to which the downlink signal is output. Convert to another signal that can be done. Specifically, the signal conversion unit 503 can realize its function by, for example, executing a program stored in the memory 403 shown in FIG. 4 by the CPU.

The signal conversion unit 503 sets a plurality of types of uplink signals (specifically, for example, uplink signals of different elevator manufacturers) as signals having the same meaning as the uplink signals, and the new control panel 106'is used. It may be converted to another signal that can be understood. That is, the signal Sa peculiar to the component part of the manufacturer A can be converted into Sz which is a signal having the same meaning as the signal and can be understood by the new control panel 106', and the signal Sb peculiar to the component part of the manufacturer B can be converted. It is a signal having the same meaning as a signal, and can be converted into an Sz that can be understood by the new control panel 106'. Therefore, the signal conversion unit 503 can convert the signal to Sz after distinguishing the signals (Sa, Sb) peculiar to the component units of each manufacturer. As for the downlink signal, it is possible to deal with a plurality of types as well as the uplink signal.

The output unit 504 on the new control panel 106'side outputs an uplink signal converted into another signal that the new control panel 106'can understand by the signal conversion unit 503 to the new control panel 106'. The output unit 504 on the side of the new control panel 106'can be realized by the output terminal 404 (connection terminal) provided corresponding to the new control panel 106'.

The output unit 505 on the component side can be realized by a plurality of output terminals 404 (connection terminals) provided for each component.

(Replacement procedure of control panel 106)
Next, the processing procedure of the replacement work method of the first embodiment according to the present invention will be described. FIG. 6 is a flowchart showing a processing procedure of the replacement work method of the first embodiment according to the present invention. 7A to 7D are explanatory views showing an outline of a replacement process of the replacement work method of the first embodiment according to the present invention. The procedure for exchanging the control panel 106 using the signal converter 400 will be described. FIG. 6 shows a procedure for replacing the control panel 106 using the signal conversion device 400. 7A to 7D show an outline of the exchange process of the control panel 106 using the signal conversion device 400. 6 and 7A to 7D show a replacement procedure for replacing the old control panel 106 with the new control panel 106'.

The new control panel 106'accepts the input of a signal to the new control panel 106' and outputs a signal based on the input signal. 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 by two values of "0" and "1", and is a signal different from the signal that the control panel 106 can understand. to understand.

Further, the new control panel 106'is a signal having the same meaning as the signal output by the control panel 106 to the plurality of component units (components A to D) 700 controlled by the control panel 106, and has the same configuration. Outputs a signal different from the signal that the unit can understand. The new control panel 106'may output a signal that can be understood by the component unit 700 to the plurality of component units 700 controlled by the control panel 106 in the same manner as the signal output by the control panel 106.

In FIG. 6, when replacing the control panel 106 using the signal conversion device 400, first, the connection between the old control panel 106 connected as shown in FIG. 7A and each component 700 is disconnected, and FIG. 7B 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 component 700 in step S602 (step S603). The new control panel 106'is installed in the vicinity of the control panel 106, for example.

Only one signal conversion device 400 may be connected, or a plurality of signal conversion devices 400 may be connected. When connecting a plurality of signal conversion devices 400, the plurality of signal conversion devices 400 correspond to a plurality of types of uplink signals and downlink signals (specifically, for example, uplink signals of different elevator manufacturers). Connect what you want. That is, the signal conversion device 400 for the component part of the A manufacturer is connected to the component part of the A manufacturer, and the signal conversion device 400 for the component part of the B manufacturer is connected to the component part of the B manufacturer. It may be.

In FIG. 7D, the new control panel 106'and the signal conversion device 400 are drawn as if they are connected by a single cable 701. In this cable 701, each component A to D700 is connected. It is connected to the new control panel 106'via the signal conversion device 400.

After that, the operation is confirmed (step S604), and it is determined whether or not the elevator 100 operates normally (step S605). In step S604, for example, the operation of the new control panel 106'based on the uplink signal input from each component 700 to the new control panel 106' via the signal conversion device 400 is confirmed. Specifically, for example, the destination floor button on the operation panel 101b of the basket 101 is operated to confirm whether or not the basket 101 moves up and down to the designated floor.

Further, in step S604, for example, the operation of each component 700 according to the downlink signal input from the new control panel 106'via the signal conversion device 400 is confirmed. Specifically, for example, the operation panel 111 provided at the landing 110 is operated, a call is generated on the corresponding floor in response to the operation, and it is confirmed whether or not the basket 101 moves to the floor. ..

In step S605, based on the confirmation result in step S604, whether the new control panel 106'operates based on the uplink signal input from each component 700 to the new control panel 106'via the signal conversion device 400 or not. The elevator 100 is normal based on the results such as whether or not the component 700 of the above is operated and whether or not it is operated according to the downlink signal input from the new control panel 106'via the signal conversion device 400. Judge whether it works or not.

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

In step S606, for example, the connection state between the component unit 700 that did not operate according to the signal output from the new control panel 106'and the new control panel 106' is confirmed. Then, after adjusting the connection state between the corresponding component 700 and the new control panel 106', it is repeatedly determined whether or not the elevator 100 operates normally until the elevator 100 operates normally (step S605). ).

(Replacement procedure of component 700)
Next, the processing procedure of the replacement work method of the first embodiment according to the present invention will be described. FIG. 8 is a flowchart showing a processing procedure of the replacement work method of the first embodiment according to the present invention. 9A to 9E are explanatory views showing an outline of a replacement process of the replacement work method of the first embodiment according to the present invention. The procedure for exchanging the component 700 using the signal converter 400 will be described. FIG. 8 shows a procedure for replacing the component 700. 9A to 9E show an outline of the replacement process of the component 700. In FIGS. 8 and 9A to 9E, 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'. The replacement procedure for replacement is shown.

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 is performed. A new component 700'instead of the removed old component 700 is connected to the board 106'(step S802). As a result, the old component 700 can be replaced with the new component 700'.

When a plurality of old component 700s are replaced with new components 700', in step S802, as shown in FIG. 9C, the corresponding old component 700 is replaced with the signal conversion device 400 for each component 700 to be replaced. The work of connecting the new component 700'in place of the removed old component 700 to the new control panel 106' is performed.

When all the old components 700 are replaced with the new components 700', as shown in FIG. 9D, all the new components 700' are directly connected to the new control panel 106', and the new control panel 106' and the new components are connected. A direct signal is exchanged with the 700'. As a result, the signal conversion device 400 may be removed after all the old components 700 have been replaced with the new components 700'. The removed signal converter 400 can be reused for the renewal of another elevator 100.

Next, the operation of the elevator 100 in which the old component 700 is replaced with the new component 700'is checked (step S803), and it is determined whether or not 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 confirmed whether or not each component 700 operates according to the output signal. Alternatively, in step S803, only the operation check of the replaced new component 700'may be performed.

Further, in step S803, for example, it is confirmed whether or not the new control panel 106'operates based on the signals output from each component 700. Specifically, for example, the destination floor button on the operation panel 101b of the basket 101 is operated to confirm whether or not the basket 101 moves up and down to the designated floor.

In step S805, based on the confirmation result in step S803, whether or not the elevator 100 operates normally based on whether or not all the components 700 operate according to the signal output from the new control panel 106'. To judge.

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

In step S805, for example, the connection state between the component 700 and the new control panel 106'that did not operate according to the signal output from the new control panel 106' is confirmed. Then, after adjusting the connection state between the corresponding component 700 and the new control panel 106', it is repeatedly determined whether or not the elevator 100 operates normally until the elevator 100 operates normally (step S804). ).

Further, FIG. 9E shows a modified example of the replacement process of the replacement work method shown in FIG. 9D. In FIG. 9E, instead of the new component B700', a new component B701 of another manufacturer, which cannot directly exchange signals with the new control panel 106', is connected. Since the new component B701 of another manufacturer cannot be directly connected to the new control panel 106', it is connected to the signal converter 400. The new component D700'has the same structure as that shown in FIG. 9D.

Then, the signal conversion device 400 converts the signal output by the new configuration unit C701 of another manufacturer into another signal having the same meaning as the signal and which can be understood by the new control panel 106'. The signal output by the control panel 106'may be converted into another signal having the same meaning as the signal and which can be understood by the new component C701 of another manufacturer.

By doing so, even if a part of the component to be replaced is a component that cannot be directly controlled by the new control panel 106', for example, a component of another manufacturer or a component having different specifications. Can be exchanged. As a result, the degree of freedom in selecting replacement parts and the like is increased, and a renewal that meets the demand can be realized.

In this way, in the replacement work of replacing the configuration unit 700 with the new configuration unit 700', the control panel 106 is controlled by connecting the signal conversion device 400 between each configuration unit 700 and the new control panel 106'. The new control panel 106'can understand the signal output by the component 700 even when the new control panel 106'operates according to a program written in a programming language different from the program used by the panel 106. ..

Further, even when the control panel 106 is replaced 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 signal output by the new control panel 106'is configured. The unit 700 can understand and operate accurately.

In the maintenance management of the elevator 100, for example, the operation history of the elevator 100 to be maintained and managed is periodically confirmed or confirmed based on the communication result between the control panel 106 of the elevator 100 and the inspection terminal. It is realized by exchanging parts based on. Further, maintenance management of the elevator 100 is realized, for example, by periodically communicating between the control panel 106 and the management server computer, executing a diagnostic operation, and replacing parts according to the result of the diagnostic operation. ..

In the maintenance management of the 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 a part of the component 700 with a new component 700', the new component 700 is used. It is assumed that the component 700'cannot be controlled by the existing ASIC. In such a situation, the new component 700'is limited to those that can be controlled by the existing ASIC.

More specifically, for example, in the elevator 100 in which each component 700 is controlled by a dedicated ASIC, when the hoist is to be replaced, the power consumption is higher than that of the existing component (winder) 700. Even if there is another hoist with low power and high output, it cannot be replaced with another hoist due to the limitation of the existing ASIC. Therefore, the person in charge of managing the elevator 100 has no choice but to choose either to replace it with an existing ASIC-controllable hoisting machine or to renew the existing ASIC. There was a situation in which the degree of freedom of maintenance management by 100 managers was low.

Further, the communication between the control panel 106 and the terminal for inspection related to the maintenance and management of the elevator 100, or the communication between the control panel 106 and the management server computer, uses a signal unique to each manufacturer of the elevator 100. The current situation was that communication was often carried out. For this reason, it is difficult for an independent maintenance service company for the elevator 100, which is independent of the manufacturer and the elevator management company affiliated with the manufacturer (hereinafter, appropriately referred to as "manufacturer, etc."), to perform maintenance management.

In the current situation where communication is performed using signals unique to each manufacturer during maintenance of the elevator 100, the new component 700'instead of the component 700 should be selected within the range specified by the manufacturer of each elevator 100. There was no choice but to have a low degree of freedom in maintenance management by the person in charge of managing the elevator 100.

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

The safety and 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 costs in the above situations, maintenance costs can be reduced by limiting the frequency of maintenance and inspection to the minimum or close to the minimum specified by the guidelines of the Ministry of Land, Infrastructure, Transport and Tourism. It becomes difficult to achieve both the reduction of the number of elevators and the improvement of the safety of the users of the elevator 100.

On the other hand, according to the replacement work method of the first embodiment, as described above, the control panel 106 is replaced with the new control panel 106', which is performed prior to the replacement of the component 700 with the new component 700'. By connecting the signal conversion device 400 between the new control panel 106'and the component 700', the elevator 100 can be operated even when the component 700 and the new component 700' coexist. be able to. As a result, the replacement work from the component unit 700 to the new component unit 700'is distributed for each component unit 700, and the elevator 100 can be operated during each replacement work.

In the first embodiment described above, the elevator 100 that controls each component 700 by executing various processes such as signal conversion processing using the CPU has been described, but the control of the elevator 100 is realized by using the CPU. It is not limited to what you do. Instead of a CPU, for example, an ASIC (Application Specific Integrated Circuit), which is an integrated circuit for a specific application in which a plurality of circuits are integrated, and an FPGA (Field-Programmable Gate Array), which is an integrated circuit whose configuration can be arbitrarily set after manufacturing. ) And the like to realize the control of the elevator 100.

Although the rope-type elevator 100 has been described in the first embodiment described above, the elevator 100 according to the present invention is not limited to the rope-type elevator 100. Instead of the rope type elevator 100, or in addition to the rope type elevator 100, for example, a hydraulic elevator 100 may be used.

Further, in the first embodiment described above, the replacement work method when the control panel 106 having a communication function is replaced with the new control panel 106'has been described, but the control panel 106 is limited to the one having a communication function. No. For example, even when the control panel 106 to which a separate communication device is connected is replaced with a new control panel 106'after installation because it does not have a communication function because remote monitoring was not assumed at the time of installation. The replacement work method according to the present invention can be applied. In this case, for example, the control panel 106 and the communication device are replaced with the new control panel 106'.

As described above, the replacement work method of the first embodiment according to the present invention is a replacement work method in which the plurality of components are replaced in an elevator having a plurality of components consisting of only one hoistway. The signal output by the component unit 700 when the control panel 106 is replaced with the new control panel 106'is a signal having the same meaning as the signal and is another signal that the new control panel 106' can understand.
