Abstract

The purpose of the present invention is to renovate an elevator without inconveniencing the users of the elevator. When replacing control panels with new control panels (106'-1 to 106'-3), a signal converter (400-1 to 400-3) that converts a signal output from a component (700-1 to 700-3) into a different signal having the same meaning as the signal and understandable to a new control panel (106'-1 to 106'-3) is connected between each new control panel (106'-1 to 106'-3) and the corresponding components (700-1 to 700-3), after which at least one of the components (700-1 to 700-3) is replaced with a new component (700'-1, 700'-2) that outputs a signal which is understandable to the new control panel (106'-1 to 106'-3). By this replacement work method, the replacement of components (700-1 to 700-3) with new components (700'-1, 700'-2) can be spread out. Furthermore, the signal converters (400-1 to 400-3) function as group management devices for managing an elevator group.

Description

Signal converter and replacement construction method

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

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

エレベーター In addition, with the recent improvement in technology, elevators controlled using new technologies have much better functions and performance than existing elevators. Therefore, when the elevator is renewed, the control panel for controlling the drive mechanism and the like is often updated. With the update of the control panel, various wirings for connecting components such as a drive mechanism and the control panel are also updated.

As a related technique, specifically, conventionally, a guide sleeve extending from an existing wiring passage into the hoistway is cut at the introduction portion on the hoistway side, and a new protective sleeve is installed in place of the guide sleeve remaining after cutting. There has been a technology in which various kinds of new wiring are laid in the hoistway through the wiring passage so that various kinds of wiring are passed from the control panel to the hoistway without performing special drilling work (for example, See Patent Document 1.).

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

JP 2006-347681 A JP 2011-162294 A

However, when the elevator is renewed with the control panel being updated, the elevator cannot be operated until all the components constituting the elevator, such as the car, the driving mechanism, and various wirings, in addition to the control panel, have been updated. For this reason, the conventional techniques including Patent Document 1 described above have a problem that the construction period is long, the period during which the elevator cannot be used is long, and the user of the elevator is inconvenienced.

The inconvenience in this case includes, for example, inconvenience that one hoistway, that is, an elevator having only one aircraft has to be renewed, so that it is necessary to go up and down the building by means other than the elevator such as stairs (at least 2). If the building has more than two elevators, transportation efficiency may be reduced, but there is no need to go up and down the building by other means such as stairs.)

何 The number of elevators depends on the size of the building. A relatively small building having only one elevator has a high existence rate. The fact that the operating rate of an elevator installed in such a relatively small building (there is only one hoistway (basket)) is 0 (zero) means that the operating rate simply decreases. This would give the user incalculable inconvenience.

Further, in the technology described in Patent Document 2, the system is suspended and renewed in units of hoistways (cars) (units of units A and B). There was a problem that it was not possible to replace each copy separately. This technology relates to group management of a plurality of elevators in a building having at least two elevators. If a plurality of elevators are provided in a building, as described above, the transportation efficiency is increased. Although it may go down, there is no need to go up and down the building by other means, such as stairs.

Hereinafter, preferred embodiments of a signal conversion device and a replacement 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 an elevator that is a target of the replacement construction method according to the first embodiment of the present invention will be described. FIG. 1 is an explanatory diagram illustrating a configuration of an elevator in a replacement construction method according to an embodiment of the present invention.

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

The elevator 100 includes only one basket (riding basket) 101 on which people and articles are mounted. One basket 101 is provided for a single unit, that is, one elevator 100. The basket 101 is provided in one hoistway (not shown in FIG. 1) penetrating each floor of the building in a vertical direction, that is, along the moving direction of the basket 101.

As will be understood from FIG. 10 described later, the elevator 100 that operates alone has only one car 101 and thus has one hoistway (in FIG. 10, three elevators that operate alone (1 No. 100-1, No. 2 100-2, and No. 3 100-3). In FIG. 1, only one hoist 104 and one rope 103 are drawn for one car 101, respectively. Therefore, the elevator according to the first embodiment is an elevator that operates alone, that is, , An elevator provided with only one car, which is provided with an elevator device configuration such as a car 101, a shock absorber 102, a rope 103, and a hoist 104 in one hoistway. That is, this is an elevator including only one hoistway and having a plurality of components. In addition, the elevator 100 that operates alone here includes components controlled by a control panel 106 described later, and does not include components outside the building such as a monitoring center.

The hoistway has a guide rail (not shown) for guiding the position of the basket 101 on the side surface. In addition, the hoistway is provided with a shock absorber 102 at the bottom for cushioning an 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 relieves an impact using the elastic force of a spring, or may be an oil-filled shock absorber 102 that relieves an impact using a hydraulic resistance. The shock absorber 102 may be provided also on the ceiling surface of the hoistway.

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

The hoist 104 in the rope-type 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, when the elevator 100 has no machine room, the hoisting machine 104 may be provided at a lower portion of the elevator 100.

The hoisting machine 104 is controlled using, for example, an inverter, and is driven and controlled by the control panel 106 so as to stop rotation on the floor where the car 101 is stopped. In the rope-type elevator 100, the basket 101 is moved up and down by using a frictional force (traction) between the rope 103 and the pulley generated by driving the hoisting machine 104. The drive of the hoist 104 is controlled by a control panel 106 provided 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 rotating position of the hoisting machine 104 based on an output signal from the encoder. As the encoder, for example, an absolute encoder may be used, or an incremental encoder may be used.

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

(4) The electromagnetic brake 107 stops rotation of the hoisting machine 104 when power supply is stopped due to a power failure or the like. As the electromagnetic brake 107, specifically, for example, a non-excitation type electromagnetic brake 107 that operates by the force of a spring to stop the rotation of the hoisting machine 104 when the power supply to the coil is cut off, for example, during a power failure, is used. be able to.

速 Governor 108 detects excess speed of car 101. The governor 108 can be realized by, for example, a centrifugal governor provided with a governor rope 108a, a governor pulley 108b, a rotary weight (not shown), and the like. In such a governor 108, the governor rope 108a is linked 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 rotating weight operates to open to the outer peripheral side of the governor pulley 108b when the rotational speed of the governor pulley 108b is high, and closes to the inner peripheral side of the governor pulley 108b when the rotational speed of the governor pulley 108b is low. Works like that.

The limit switch 109 has a switch lever (not shown) for switching between supply and cutoff of power to the hoist 104. The switch lever is positioned at a position for supplying power to the hoist 104 during normal times, and shuts off power supply to the hoist 104 when urged by the rotating weight of the governor 108. Displace to position.

The rotating weight of the governor 108 is displaced to a position where the switch lever cuts off the supply of power to the hoisting machine 104 when the elevating speed of the car 101 becomes equal to or higher than the rated speed. Next, the switch lever is biased. Thus, when an 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 include an emergency stop device. The emergency stop device forcibly 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 operates even though the governor rope 108a is stopped. Stop. The emergency stop device can be easily realized by using various known techniques, and thus the description thereof is omitted.

The basket 101 has a door 101a. The basket 101 includes a motor (not shown) for opening and closing the door 101a, a door open / close sensor (not shown) for detecting 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.

(4) The output of the door open / close sensor changes depending on whether the door 101a or the door 110a is open or closed according to 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 a signal output from the door opening / closing sensor is input to the control panel 106 via the wiring.

扉 A door 110a is provided at a position (platform) 110 corresponding to each floor in the hoistway. The door 110a provided at the landing 110 is locked by a device called an interlock (not shown). The interlock engages with the opening / closing mechanism of the door 101a of the car 101 to release the lock only when the motor of the car 101 is driven while the elevator 100 arrives at the stop floor. Accordingly, 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.

操作 Each landing 110 is provided with a control panel 111 including a landing call button 111a, a display 111b for displaying a floor or the like where the car 101 is located, and the like. The operation panels 111 each include a control board 111c for the operation panel 111, and are connected to the control panel 106 via the control board 111c.

(Configuration of the basket 101 and the operation panel 101b provided on the basket 101)
Next, the configuration of the car 101 and the operation panel 101b provided on the car 101 will be described. FIG. 2 is an explanatory diagram showing the car 101 and an operation panel 101b provided on the car 101.

In FIG. 2, the operation panel 101b is provided on the inner wall surface of the car 101 and near the door 101a of the car 101. The operation panel 101b includes operation buttons 201 including a destination floor button for designating a destination floor of the car 101, a door opening / closing button for supporting opening / closing of the door 101a, and the like. Further, the operation panel 101b includes a display 202 for displaying a floor or the like where the car 101 is located.

The operation panel 101b provided on the basket 101 has 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 or the like of the elevator 100, the control board generates a call signal corresponding to the input operation and outputs the generated call signal to the control panel 106. .

The control board for the operation panel 101b outputs a signal corresponding to the output of the door open / close sensor to the control panel 106, for example. Further, the control board for the operation panel 101b controls the display 202 in accordance with the signal output from the control panel 106, and displays the floor where the car 101 is located. The control board for the operation panel 101b may perform switching control of turning on / off the lighting 203 provided on the car 101, drive control of the monitoring camera 204, and the like.

カ The car 101 is provided with an intercom terminal device 205. The terminal device 205 of the interphone includes a call button, a microphone, and a speaker (both are not shown). The microphone and speaker in the intercom terminal device 205 may be integrated into the operation panel 101b. The terminal device 205 of the interphone is connected to the control panel 106 similarly to the control board for the operation panel 101b. It is connected to the control panel 106.

(Configuration of platform 110 and operation panel 111 provided at platform 110)
Next, the configuration of the landing 110 and the operation panel 111 provided in the landing 110 will be described. FIG. 3 is an explanatory diagram showing the configuration of the landing 110 and the operation panel 111 provided in the landing 110.

The landing call button 111a provided in each operation panel 111 is provided, for example, on the wall surface 301 near the door 110a. For example, each of the displays 111b that displays the floor where the basket 101 is located is provided on a wall surface 302 or the like above the door 110a. For example, as shown in FIG. 3, the display 111b displays the floor where the car 101 can be stopped and the floor where the car 101 is located. The display 111b may display only the floor where the basket 101 is located. The elevator 100 does not need to include the display 111b.

Like the control board for the operation panel 101b, the control board 111c generates a call signal corresponding to the input operation each time an input operation on the hall call button 111a by the user of the elevator 100 or the like is performed, and generates the generated call signal. The signal is output to the control panel 106.

In the first embodiment, the components according to the present invention can be realized by, for example, each of the components included in elevator 100 that outputs a signal to control panel 106, a so-called “up signal”. Further, in the first embodiment, among the units included in elevator 100, for example, each unit that operates according to a signal output from a CPU (Central Processing Unit) of control panel 106, that is, a so-called “down signal”, provides the present invention. According to the present invention, it is possible to realize the components according to the above.

Specifically, the components can be realized by, for example, the drive mechanism of the elevator 100. More specifically, the drive mechanism of the elevator 100 can be realized by, for example, a hoist 104, an electromagnetic brake 107, a motor that opens and closes the door 101a, and the like. Such a driving mechanism of the elevator 100 operates according to a down signal output from the control panel 106. Further, the drive mechanism of the elevator 100 may further output an up signal to the control panel 106.

The components can be realized by, for example, a control mechanism of the landing 110 of the elevator 100. Specifically, the control mechanism of the landing 110 of the elevator 100 can be realized by, for example, an operation panel 111 (control board 111c) provided at each landing 110. The components can be realized by a control mechanism of the car 101 of the elevator 100. Specifically, the control mechanism of the car 101 of the elevator 100 can be realized by, for example, an operation panel 101b provided on the car 101.

構成 Further, the components can be realized by, for example, the sensor mechanism of the elevator 100. Specifically, the sensor mechanism of the elevator 100 can be realized by various sensors such as a limit switch 109 and a door open / close sensor. These various sensors output an up signal to the control panel 106.

(Configuration of control panel 106)
Next, the configuration of the control panel 106 will be described. The control panel 106 includes an input terminal, an output terminal, a CPU, a memory, and a communication I / F (Interface) (all are not shown). Each part of the control panel 106 is connected to each other by a bus (not shown).

The input terminal of the control panel 106 is a hardware interface that connects a plurality of components included in the elevator 100 and the CPU of the control panel 106, and receives an input of a signal output from each component and receives the input. The signal is output to the CPU of the control panel 106. The input terminal of control panel 106 receives, for example, an input of an up signal output from each component of elevator 100 to control panel 106.

Specifically, the input terminal of the control panel 106 receives an input of a call signal output from, for example, a control board for the operation panel 101b or a control board for the operation panel 101b. The input terminal of control panel 106 receives, for example, an input of a signal output from an encoder. 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, a photoelectric sensor, or the like.

The output terminal of the control panel 106 is a hardware interface that connects a plurality of components included in the elevator 100 and the CPU of the control panel 106, and outputs a down signal output from the CPU of the control panel 106 to the corresponding component. Output. Specifically, the output terminal of the control panel 106 transmits, for example, a 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 car 101, and the door 110a of the landing 110. Output to motors that open and close.

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 performs arithmetic processing using a program, data, or the like stored in the memory based on, for example, an upstream signal input via an input terminal. Further, the CPU of control panel 106 outputs a signal based on the result of the arithmetic processing, for example, to the corresponding component via an 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 up signal (call signal) output from a control board for the operation panel 101b. A control down signal for each component such as a motor is generated, and the generated control down signal is output to each corresponding component. In addition, the CPU of the control panel 106 determines whether or not each component operates normally based on an up signal output from each component such as the hoisting machine 104 (encoder), the brake sensor, and the door opening / closing sensor. Judge. Further, the CPU of the control panel 106 outputs a down signal for control including a floor signal indicating the floor where the car 101 is located, for example, to a control board for the operation panel 101b. The floor on which the car 101 is located, the direction of movement (whether it is ascending or descending) and the like are displayed.

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

(4) The communication I / F transmits a signal for alarm output from the CPU of the control panel 106 to the management server computer. The signal for alarm 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.

(4) The communication I / F receives various instructions such as a diagnostic operation execution instruction transmitted from the management server computer and outputs the instructions to the CPU of the control panel 106. The diagnostic operation is performed by causing the control panel 106 to output signals for operating the respective units in a predetermined order to the respective units included in the elevator 100, and indicating whether or not the respective units operate normally in accordance with the output signals. Is output from the control panel 106. The management server computer (not shown) outputs an instruction to execute a diagnostic operation, for example, periodically (for example, every time the last day of the month comes).

By connecting the control panel 106 and the management server computer via the Internet instead of the public voice network such as a telephone line via the communication I / F, the telephone line is punctured in the event of an emergency such as a natural disaster such as an earthquake. As a result, it is possible to avoid delay in grasping the situation of the elevator 100. Accordingly, in a situation where the elevator 100 is remotely monitored using the management server computer, a quick response can be taken in the event that a malfunction occurs in the operation of the elevator 100.

The control panel 106 may be further connected to a public voice network via a communication I / F. Public voice networks include fixed telephone networks (public switched telephone networks) and cellular telephone networks. The public voice network is composed of a plurality of switches (not shown) such as a subscriber line exchange accommodating a telephone line, a relay exchange bundling the subscriber line exchanges, and a gateway exchange connecting to a telephone network of another operator. . Description of the public voice network is omitted because it is a known technique.

(4) By connecting the control panel 106 to a public voice network via a communication I / F, voice communication between the terminal device 205 of the interphone and the management center can be realized. In this case, specifically, for example, a communication I / F can be realized by 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 not only for voice communication but also for data communication. Since the installation location of the elevator 100 is fixed, by performing communication using the PHS, the quality of communication can be ensured and the cost for communication can be suppressed. This makes it possible to achieve both data communication between the control panel 106 and the management server computer and voice communication between the interphone terminal device 205 and the management center at low cost.

Specifically, the function of the signal conversion unit 503 can be realized when the CPU executes a program or the like stored in the memory 403 illustrated in FIG. 4, for example.

The signal conversion unit 503 converts a plurality of types of upstream signals (specifically, for example, upstream signals of different elevator manufacturers, respectively) into signals having the same meaning as the upstream signals, and the new control panel 106 ′ You may make it convert into another signal which can be understood. That is, the signal Sa specific to the component part of the manufacturer A can be converted into a signal having the same meaning as the signal and understood by the new control panel 106 ′, and the signal Sb specific to the component part of the manufacturer B is converted The signal has the same meaning as the signal, and can be converted into Sz that can be understood by the new control panel 106 '.

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

(4) The new control panel 106 'receives a signal input 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 described 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 of “0” and “1”, and a signal different from the signal that the control panel 106 can understand. to understand.

The new control panel 106 ′ is a signal having the same meaning as the signal output from the control panel 106 to a plurality of components (components A to D) 700 controlled by the control panel 106. A signal different from the signal that the unit can understand is output. The new control panel 106 ′ may output a signal that can be understood by the component 700 to a plurality of components 700 controlled by the control panel 106, similarly to 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 old control panel 106 connected as shown in FIG. The old control panel 106 is removed (step S601).

Next, as shown in FIG. 7C, the signal converter 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 hoistway wall. Then, as shown in FIG. 7D, the new control panel 106 ′ is connected to the signal conversion device 400 connected to the configuration unit 700 in step S602 (step S603). The new control panel 106 'is installed, for example, near the control panel 106.

Only one signal conversion device 400 may be connected, or a plurality of signal conversion devices 400 may be connected. When a plurality of signal converters 400 are connected, each of the plurality of signal converters 400 supports a plurality of types of upstream signals and downstream signals (specifically, for example, upstream signals of different erasure manufacturers). Connect what you want. That is, the signal converter 400 for the component part of the manufacturer A is connected to the component part of the manufacturer A, and the signal converter 400 for the component part of the manufacturer B is connected to the component part of the manufacturer B. It may be.

In FIG. 7D, the new control panel 106 'and the signal conversion device 400 are illustrated as being connected by a single cable 701. In the cable 701, the components A to D700 are respectively provided. It is connected to the new control panel 106 'via the signal converter 400.

(5) After that, an operation check is performed (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 an uplink signal input from each component 700 to the new control panel 106' via the signal conversion device 400 is confirmed. Specifically, for example, a destination floor button on the operation panel 101b of the car 101 is operated to check whether or not the car 101 moves up and down to the designated floor.

In step S604, for example, the operation of each component 700 according to a downstream 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 according to the operation, and it is confirmed whether or not the car 101 moves to the floor. .

In step S605, based on the confirmation result in step S604, whether or not 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 The elevator 100 operates normally based on the result of whether the component 700 has operated according to the down signal input from the new control panel 106 'via the signal converter 400, and the like. It is determined whether or not to operate.

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

In step S606, for example, the connection state between the component 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, a processing procedure of the replacement construction method according to the first embodiment of the present invention will be described. FIG. 8 is a flowchart illustrating a processing procedure of the replacement construction method according to the first embodiment of the present invention. 9A to 9E are explanatory diagrams showing an outline of the replacement process of the replacement construction method according to the first embodiment of the present invention. An exchange procedure of the component 700 using the signal conversion device 400 will be described. FIG. 8 shows a procedure for replacing the component 700. 9A to 9E show the outline of the replacement process of the configuration unit 700. 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 exchange procedure at the time of exchange 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. A new component 700 ′ replacing the removed old component 700 is connected to the board 106 ′ (step S802). Thus, the old component 700 can be replaced with the new component 700 ′.

When replacing a plurality of old constituent parts 700 with new constituent parts 700 ', in step S802, as shown in FIG. 9C, for each constituent part 700 to be replaced, the corresponding old constituent part 700 is replaced with a signal conversion device 400. Then, work is performed to connect the new component 700 'replacing the removed old component 700 to the new control panel 106'.

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 A signal is directly exchanged with the signal 700 '. Thus, after all the old components 700 are replaced with the new components 700 ', the signal conversion device 400 may be removed. The removed signal converter 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 confirmed 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.

In step S <b> 803, for example, it is confirmed whether or not the new control panel 106 ′ operates based on a signal output from each component 700. Specifically, for example, a destination floor button on the operation panel 101b of the car 101 is operated to check whether or not the car 101 moves up and down to the designated floor.

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

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

In step S805, for example, the connection state between the component 700 that did not operate according to the signal output from the new control panel 106 'and the new control panel 106' is checked. Then, after adjusting the connection state between the corresponding 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 S804). ).

FIG. 9E shows a modification of the replacement process of the replacement construction 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. Note that the new configuration unit D700 'has the same configuration as that shown in FIG. 9D.

Then, the signal conversion device 400 converts the signal output by the new component C701 of another manufacturer into another signal having the same meaning as the signal and understandable by the new control panel 106 ′. The signal output from the control panel 106 'may be converted to another signal having the same meaning as the signal and 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 with a different specification, Can be subject to exchange. As a result, the degree of freedom in selecting replacement parts and the like is increased, and renewal more desirably can be realized.

As described above, when the component 700 is replaced with the new component 700 ′, the control panel 106 is controlled by connecting the signal conversion device 400 between each component 700 and the new control panel 106 ′. Even when the control panel 106 'is replaced with a new control panel 106' that operates according to a program described in a programming language different from the program used by the panel 106, the signal output by the component 700 can be understood by the new control panel 106 '. .

Also, when the control panel 106 is replaced with a new control panel 106 ′ that operates according to a program described in a programming language different from the program used by the control panel 106, the signal output from the new control panel 106 ′ is configured. The unit 700 can understand and operate correctly.

The maintenance management of the elevator 100 is performed, for example, based on the communication result between the control panel 106 of the elevator 100 and the terminal for inspection, periodically confirming the operation history of the elevator 100 subject to maintenance management, or confirming the confirmed operation history. This is realized by exchanging parts based on The maintenance 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 exchanging parts according to the result of the diagnostic operation. .

Conventionally, in such 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 some components 700 with a new component 700 ′, 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 a component 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, power consumption is higher than that of the existing component (hoist) 700. Even if there is another hoisting machine with low power and high output, it cannot be replaced with another hoisting machine due to the limitation by the existing ASIC. For this reason, the person in charge of managing the elevator 100 must select either to replace the hoisting machine that can be controlled by the existing ASIC or to renew the existing ASIC. There was a situation in which the degree of freedom of maintenance management by 100 managers was low.

In addition, communication between the control panel 106 for maintenance and management of the elevator 100 and the terminal for inspection, or communication between the control panel 106 and the management server computer uses a signal unique to each manufacturer (maker) of the elevator 100. There was a current situation that communication was often performed. For this reason, it has been difficult for an independent elevator 100 maintenance service company independent of a manufacturer or an elevator management company affiliated with the manufacturer (hereinafter referred to as “manufacturer or the like” as appropriate) to perform maintenance management.

In the current situation in which communication using a signal unique to each manufacturer is performed during maintenance management of the elevator 100, the new component 700 'instead of the component 700 can be selected within a range specified by the manufacturer of each elevator 100 or the like. Inevitably, there has been a situation where the degree of freedom of maintenance management by the manager of the elevator 100 or the like is low.

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

(4) The safety and security of the user 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, if the frequency of maintenance and inspections is reduced to the minimum specified by the guidelines of the Ministry of Land, Infrastructure, Transport and Tourism or close to it, maintenance and management costs will be reduced. It is difficult to achieve both the reduction of the number of times and the improvement of the safety of the user of the elevator 100.

On the other hand, according to the replacement construction method of the first embodiment, as described above, the replacement of the control panel 106 with the new control panel 106 'is performed prior to the replacement of the component 700 with the new component 700'. Before, the signal converter 400 is connected between the new control panel 106 'and the component 700 to operate the elevator 100 even when the component 700 and the new component 700' coexist. be able to. Thus, the replacement operation from the component 700 to the new component 700 'can be performed separately for each component 700, and the elevator 100 can be operated during each replacement.

In the first embodiment described above, the elevator 100 that controls each component 700 by executing various processing such as signal conversion processing using the CPU has been described. However, control of the elevator 100 is realized using the CPU. It is not limited to what you do. Instead of the 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, or an FPGA (Field-Programmable Gate Array) which is an integrated circuit whose configuration can be arbitrarily set after manufacturing ) May be used to realize control of the elevator 100.

In the first embodiment described above, the rope-type elevator 100 has been described, but 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 type elevator 100 may be used.

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

As described above, the replacement work method according to the first embodiment of the present invention is a replacement work method for performing replacement work on a plurality of components in an elevator including only one hoistway and having a plurality of components. When the control panel 106 is replaced with a new control panel 106 ', a signal output from the component 700 is a signal having the same meaning as the signal and another signal that the new control panel 106' can understand. A signal conversion device 400 for converting to a new control panel 106 'is connected between the new control panel 106' and the component 700, and then at least one of the components 700 outputs a signal which can be understood by the new control panel 106 ' It is characterized by being replaced with 700 '.

(Procedure for replacement work)
Next, the processing procedure of the replacement construction method according to the second embodiment of the present invention will be described. FIG. 12 is a flowchart illustrating a processing procedure of a replacement construction method according to the second embodiment of the present invention. FIGS. 13A to 13G are explanatory diagrams showing an outline of the replacement process of the replacement construction method according to the second embodiment of the present invention.

FIG. 13A shows a state of the elevator group 1000 before the replacement work is started. Here, the three elevators 100-1 to 100-3 may be replaced in any order, but in FIGS. 13A to 13G, the first elevator 100-1 first, and then the second elevator 100-1. The replacement work will be performed in the order of the elevator 100-2 and finally the elevator 100-3.

In FIG. 12, similarly to FIG. 6, when replacing the first (old) control panel 106-1 with the first new control panel 106'-1 using the first signal converter 400-1, First, the connection between the first (old) control panel 106-1 and each component 700-1 is disconnected, and the first (old) control panel 106-1 is removed (step S1201).

Next, as shown in FIG. 13B, the first unit signal converter 400-1 is connected to the component 700-1 from which the first (old) control panel 106-1 has been removed (step S1202). The first signal conversion device 400-1 can be attached to, for example, a hoistway wall. Then, as shown in FIG. 13B, the first unit new control panel 106'-1 is connected to the first unit signal converter 400-1 connected to the configuration unit 700-1 in step S1202 (step S1203). The first new control panel 106'-1 is installed, for example, near the old first control panel 106-1.

In FIG. 13B, in the first elevator 100-1, the first signal converter 400-1 and the first new control panel 106'-1 are connected, and the second elevator 100-2 and the third elevator 100 are connected. About -3, nothing is done.

(5) Thereafter, the operation is confirmed (step S1204), and it is determined whether or not the elevator 100-1 operates normally (step S1205). In step S1204, for example, the operation of the new control panel 106'-1 based on the upstream signal input from each component 700-1 to the new control panel 106'-1 via the signal conversion device 400-1 is confirmed. I do. Specifically, for example, a destination floor button on the operation panel of the car 101 is operated to check whether or not the car 101 moves up and down to the designated floor.

In step S1204, for example, the operation of each component 700-1 according to a downstream signal input from the new control panel 106'-1 via the signal conversion device 400-1 is confirmed. Specifically, for example, the operation panel 111-1 provided at the landing is operated, a call is generated on the corresponding floor in accordance with the operation, and whether the basket 101-1 moves to the floor is determined. Check.

In step S1205, based on the confirmation result in step S1204, the new control board 106 ′ based on the upstream signal input from each component 700-1 to the new control board 106′-1 via the signal conversion device 400-1. '-1 operates or whether all the components 700-1 operate, and whether the operation has been performed according to the downstream signal input from the new control panel 106'-1 via the signal converter 400-1. Whether the elevator 100-1 operates normally or not is determined based on the result of the determination.

If the elevator 100-1 does not operate normally in step S1205 (step S1205: No), the connection is confirmed (step S1206). In step S1206, for example, the connection state between the component 700-1 that did not operate according to the signal output from the new control panel 106'-1 and the new control panel 106'-1 is confirmed. Then, after adjusting the connection state between the corresponding component 700-1 and the new control panel 106'-1, whether the elevator 100-1 operates normally is repeated until the elevator 100-1 operates normally. It is determined whether or not it is (step S1205). On the other hand, in step S1205, when the elevator 100-1 operates normally (step S1205: Yes), the process proceeds to step S1207.

As shown in FIG. 13B, in this state, the first control panel 106 ′-1 is not connected to the group management device 1001. There is a case where the new control panel 106'-1 of the first unit cannot be managed by the group management device 1001, and is not connected to prevent malfunction. Therefore, the first elevator 100-1 is not under group control, and is not operating in conjunction with the second elevator 100-2 and the third elevator 100-3 (the second elevator 100-2 and the third elevator 100-2 are not operated). 100-3). However, the first elevator 100-1 can operate alone.

Next, it is determined whether the signal converter and the new control panel are attached to the adjacent elevator (step S1207). If the signal converter and the new control panel are not attached to the adjacent elevator (Step S1207: No), the process goes to Step S801 of the flowchart of FIG. Is performed. In FIG. 13B, since the signal converter and the new control panel are not attached to the elevator (No. 2 or No. 3) adjacent to the No. 1 unit, the process proceeds to Step S801 in the flowchart of FIG. 8 without doing anything.

On the other hand, in step S1207, when the signal converter and the new control panel are attached to the adjacent elevator (step S1207: Yes), the signal converters are connected (step S1208). 13C, the second unit signal converter 400-2 is connected to the configuration unit 700-2, and in FIG. 13D, the second unit new control panel 106'-2 is connected to the second unit signal converter 400-2. Since the Unit 1 signal converter 400-1 and the Unit 1 new control panel 106'-1 are attached to the adjacent Unit 1 elevator, the Unit 1 signal converter 400-1 and the Unit 2 signal converter 400-2 are installed. And are connected.

In FIG. 13C, in the first elevator 100-1, the new component A700'-1 is connected to the first new control panel 106'-1 instead of the component A700-1 (step S802 in FIG. 8). Yes, and in the second elevator 100-2, the connection of the second control panel 106-2 was disconnected (step S1201), and the second signal converter 400-2 was connected to the component 700-2 (step S1202). The construction has been progressed until now. The third elevator 100-3 is in a state where nothing is done.

(5) Thereafter, an operation check is performed (step S1209), and it is determined whether or not the group management of the elevators 100-1 and 100-2 operates normally based on the operation check result (step S1210). Here, if it does not operate normally (step S1210: No), the connection between the signal conversion devices is confirmed (step S1211), and the process returns to step S1209. After adjusting the connection between the first signal converter 400-1 and the second signal converter 400-2, until the group management of the first elevator 100-1 and the second elevator 100-2 operates normally. , And steps S1209 to S1211 are repeatedly performed.

If the group management of the elevators 100-1 and 100-2 operates normally (step S1210: Yes), the process proceeds to step S801 in the flowchart of FIG. Thus, in the state shown in FIG. 13D, group management can be performed for each elevator (the first elevator 100-1 and the second elevator 100-2) to which the signal converters are connected. After that, each processing of the flowchart of FIG. 8 is performed.

In FIG. 13D, in the first elevator 100-1, the state shown in FIG. 13C is the same (the new component A700'-1 is connected to the first new control panel 106'-1 instead of the component A700-1). In the second elevator 100-2, the second control panel 106'-2 is connected to the second signal conversion device 400-2 (steps S1203 to S1206), and the first signal conversion is performed. In this state, the apparatus 400-1 and the second-unit signal conversion apparatus 400-2 are connected (steps S1207 to S1211). The third elevator 100-3 is in a state where nothing is done.

In FIG. 13E, in the first elevator 100-1, a new component B700'-1 is connected to the first new control panel 106'-1 instead of the component B700-1. At 100-2, a new component D700'-2 is connected to the second control panel 106'-2 instead of the component D700-2. In the third elevator 100-3, the third signal converter 400-3 and the third new control panel 106'-3 are connected (steps S1201 to 1206), and the third signal converters 400-2 and 400-3 are connected. This is a state in which the signal signal converter 400-3 is connected (steps S1207 to S1211).

で In the state shown in FIG. 13E, the group management device 1000 becomes unnecessary and can be removed. In addition, since the signal converters 400-1 to 400-3 are connected and the operation is confirmed, the elevators 100-1 to 100-3 can execute group management.

FIG. 13F shows a new component (new component C700′-1, new component D700) in place of the remaining components (component C700-1, component D700-1) in the first elevator 100-1. '-1) is connected to the Unit 1 new control panel 106'-1.
