[0021] The following describes the method for replacing a control panel and the base mount according to this invention, with reference to the attached drawings. Preferred embodiments of the nt will be described in detail.

[0022] (An example of elevator configuration) First, regarding the configuration of the elevator to which the replacement work method of the embodiment of this invention applies: Let me explain. Figure 1 is an explanatory diagram showing an example of an elevator configuration.

[0023] Figure 1 shows the elevator to which the replacement work method according to the embodiment of this invention applies. 100 is installed, for example, inside a building such as a multi-story building, and is accessible from only one elevator shaft. Therefore, only one elevator is installed in the building and operates independently. Elevator 100 is, for example, This can be achieved using a rope-type (traction-type) elevator.

[0024] Elevator 100 is equipped with a car (ride car) 101 for carrying people and goods. One Go 101 is provided for each elevator shaft. Elevators connect each floor level in a building. It penetrates in the vertical direction, that is, along the direction of movement of the cage 101. In this embodiment, The elevator 100, which operates independently, is controlled by a control panel 106, which will be described later, and by the said control panel 106 It is composed of components that are controlled in this way. The elevator 100, which operates independently, This does not include external components of elevator 100, such as monitoring centers located in remote areas. .

[0025] The elevator shaft has guide rails on its sides to guide the lifting position of the elevator car 101 (illustration omitted). ) is equipped with. In addition, the elevator shaft has a bottom that is designed to withstand the event that the cage 101 falls and hits the bottom surface. It is equipped with a shock absorber 102 to mitigate the impact. The shock absorber 102 utilizes the elastic force of a spring. It may also be a spring-type shock absorber 102 that reduces impact, and may utilize hydraulic resistance to reduce impact. A buffer 102 filled with oil may also be provided. The buffer 102 may also be installed on the ceiling surface of the elevator shaft. It's okay if it's done that way.

[0026] The basket 101 is connected to one end of the rope 103. The rope 103 slides in a bucket-like fashion. It is attached to a vehicle (not shown in the illustration) and a hoisting machine (traction machine) 104, with the other end being a It is connected to the counterweight 105. The rope 103 is specifically, for example, made of steel. This can be achieved using wire.

[0027] In a rope-type elevator 100, the hoisting machine 104 is, for example, elevator 10 It is installed in the machine room located at the very top of 0. The hoisting machine 104 is, for example, an inverter It is controlled using a system that stops the rotation of the cage 101 on the floor where it is to be stopped. It is driven and controlled by the control panel 106. In the rope-type elevator 100, the hoisting machine The frictional force between the rope 103 and the pulley (traction) generated by driving 104. The cage 101 is raised and lowered using the elevator 100. The hoisting machine 104 is equipped with the elevator 100. It is driven and controlled by control panel 106.

[0028] The hoisting machine 104 is equipped with an encoder (not shown in the figure), and the control panel 106 is an encoder Based on the output signal, the rotational speed and rotational position of the hoisting machine 104 can be determined. The encoder may be an absolute encoder, for example, or an incremental encoder. A single encoder may also be used.

[0029] Furthermore, elevator 100 includes an electromagnetic brake 107, a speed governor (governor machine) 108, It is equipped with limit switches 109, etc. The electromagnetic brake 107 is equipped with a coil and control The electromagnetic force generated by energizing the coil, which is driven and controlled by the control panel 106, is utilized. The electromagnetic brake 107 stops the rotation of the hoisting machine 104. It can maintain a stopped state.

[0030] The electromagnetic brake 107 activates when the power supply is interrupted due to a power outage or the like, and the hoisting machine 104 The rotation is stopped. Specifically, the electromagnetic brake 107 stops the coil, for example, in the event of a power outage. When the power supply is cut off, the spring force activates to stop the rotation of the hoisting machine 104. A dynamic electromagnetic brake 107 can be used.

[0031] The governor 108 detects when the cage 101 is exceeding its speed. The governor 108, for example, A remote control equipped with a rope 108a, a governor pulley 108b, a rotor (not shown in the diagram), etc. This can be achieved by a governor. In such a governor 108, the governor narrow The pulley 108a is linked to the operation of the basket 101. The governor pulley 108b controls the governor rope. It rotates in conjunction with the operation of 108a.

[0032] The rotor controls the rotational speed of the governor pulley 108b, that is, the rotation of the governor pulley 108b It operates according to the magnitude of the centrifugal force caused by rotation. Specifically, the rotating weight is controlled by the governor pulley. When the rotational speed of 108b is high, it operates to open towards the outer circumference of the governor pulley 108b. When the rotation speed of the governor pulley 108b is slow, it closes to the inner circumference of the governor pulley 108b. It operates in that manner.

[0033] The limit switch 109 switches the power supply / cutoff to the hoisting machine 104. It is equipped with a switch lever (not shown in the illustration). The switch lever is normally connected to the hoisting machine 104. In contrast, it is positioned to supply power, and is biased to the rotor weight of the governor 108. At the same time, it is displaced to a position that cuts off the power supply to the hoisting machine 104.

[0034] The rotor of the governor 108 moves when the lifting speed of the cage 101 is above a certain speed relative to the rated speed. If this occurs, the switch lever will change to a position that cuts off the power supply to the hoisting machine 104. The switch lever is biased to the position. This causes the basket 101 to exceed the speed limit. When this happens, the operation of the hoisting machine 104 can be stopped, and the basket 101 can be stopped.

[0035] Furthermore, the elevator 100 may be equipped with an emergency stop device. The emergency stop device is If the operation of the basket 101 and the operation of the governor rope 108a are different, that is, the governor rope If cart 101 is operating even though p108a is stopped, cart 101 The operation is forcibly stopped. The emergency stop device can be easily implemented using various known technologies. Since it can be done this way, the explanation will be omitted.

[0036] The cage 101 is equipped with a door 101a. The cage 101 also has a mechanism to open and close the door 101a. A motor (not shown) and a door open / close sensor (not shown) that detects the open / closed state of door 101a. (The following is omitted), and it is equipped with a control panel 101b, etc. A motor for opening and closing the door 101a The turner is driven and controlled by the control panel 106 to open and close the door 101a.

[0037] The door opening / closing sensor detects the state of the safety shoe located between door 101a and door 110a. The output changes depending on whether door 101a or door 110a is open or closed. The door opening / closing sensor can be implemented using, for example, a microswitch or a photoelectric sensor. This is possible. The door opening / closing sensor is connected to the control panel 106 via wiring, and the door opening / closing sensor The signal output from is input to the control panel 106 via the wiring.

[0038] Doors 110a are provided at each position (landing) 110 corresponding to each floor level in the elevator shaft. It is being kicked. The door 110a provided at boarding area 110 has an interlock (not shown in the illustration). It is locked with a device called such as. The interlock is for elevator 100 to stop at a specific floor. The door 1 of cage 101 will only open if the motor equipped with cage 101 is activated upon arrival. The opening and closing mechanism of 01a engages with the lock and releases it. This releases the lock on the floor where the car 101 is located. Only the door 110a located at the boarding area 110 can be opened and closed in conjunction.

[0039] Each boarding area 110 has a boarding area call button 111a and a elevator car 101 located on a specific floor. A control panel 111 is installed, equipped with a display unit 111b that shows the floor, etc. Control panel 1 Each of the 11s is equipped with a control board 111c for the control panel 111, and the control board 111c It is connected to the control panel 106 via [a certain means].

[0040] The control panel 106 controls components such as the hoisting machine 104 and each of the elevator 100. Components such as sensors that output information regarding the status of the unit to the control panel 106 are connected by cables. It is connected to the control panel 106 via (see Figure 8B). For example, it is provided in the cage 101. The components are connected via a cable, such as a tail cord, which is routed through the basket 101. It is connected to the control panel 106. Specifically, for example, the door opening / closing sensor of the cage 101. Lighting (see reference numeral 203 in Figure 2), control panel 101b, and ensuring user safety. Various sensors and other components are connected to the control panel 106 via a cable (tail cord). It is connected.

[0041] Furthermore, specifically, for example, the control board 111c draws from the control board 111c through the elevator shaft. It is connected to the control panel 106 via routed cables. Also, specifically, even Then, various sensors installed in the elevator shaft, etc., are connected to the control panel 106 via cables. It is.

[0042] The control panel 106 is installed, for example, in a machine room. In this case, one end of the cable is an electric cable. It is connected to each component of the Beta 100, and routed from each component to the machine room, The other end is connected to the control panel 106. The control panel 106 is equipped with multiple connections of the elevator 100. It controls the components.

[0043] The control panel 106 receives, for example, an upward signal (call) output from the control board for the operation panel 101b. Based on the signal, the hoisting machine 104, electromagnetic brake 107, and doors 101a, 105a It controls each component, such as the motor that opens and closes the mechanism. The control panel 106 also controls, for example, hoisting. Output from each component such as unit 104 (encoder), brake sensor, and door opening / closing sensor. Based on the incoming upward signal, it is determined whether each component has operated normally. Also, control panel 1 06, for example, provides the control board for the control panel 101b with respect to the floor on which the cage 101 is located. It outputs a control down signal including the floor signal, and in the control panel 101b, the cage 101 It displays the current floor level and direction of movement (ascending or descending), etc. This is provided by the control panel 106. Each component is mounted on one or more circuit boards and housed within a box-shaped iron casing. (See Figure 8A).

[0044] (An example of the configuration of the cage 101 and the control panel 101b provided in the cage 101) Next, regarding an example of the configuration of the cage 101 and the control panel 101b provided in the cage 101... Let me explain. Figure 2 shows the configuration of the cage 101 and the control panel 101b provided in the cage 101. This is an explanatory diagram showing an example.

[0045] In Figure 2, the control panel 101b is located on the inner wall of the cage 101, and the door 1 of the cage 101 It is located near 01a. The control panel 101b is used to specify the destination floor of the elevator car 101. It is equipped with operation buttons 201, including floor buttons and door open / close buttons that support the opening and closing of door 101a. It is equipped with a display unit 2 that shows the floor level where the elevator car 101 is located. It has 02.

[0046] The control panel 101b installed in the cage 101 is equipped with a control board for the control panel 101b. It is connected to the control panel 106 via a control board for the control panel 101b. The control board for 1b is for operation of the operation button 201 by elevator users, etc. Each time an input operation is received, a call signal corresponding to that input operation is generated, and the generated call signal The code is output to control panel 106.

[0047] Furthermore, the control board for the control panel 101b, for example, sends a signal corresponding to the output of the door opening / closing sensor. The output is sent to control panel 106. Additionally, the control board for operation panel 101b outputs from control panel 106. The display unit 202 is controlled according to the signal received, and the floor level on which the elevator car 101 is located is displayed. The control board for the control panel 101b controls the on / off switching of the lights 203 installed in the cage 101. You may also perform replacement control or drive control of the surveillance camera 204.

[0048] Furthermore, the cage 101 is equipped with an intercom terminal device 205. The phone terminal device 205 is equipped with a call button, a microphone, and a speaker (all of them) (Illustrations omitted). The microphone and speaker in the intercom terminal device 205 are operated It may be integrated into the control panel 101b. The intercom terminal device 205 is It is connected to control panel 106, similar to the control board for control panel 101b.

[0049] (An example of the configuration of the boarding area 110 and the control panel 111 installed at boarding area 110) Next, we will describe an example of the configuration of the boarding area 110 and the control panel 111 installed at boarding area 110. Let me explain. Figure 3 shows the structure of the boarding area 110 and the control panel 111 installed on boarding area 110. This is an explanatory diagram showing an example of success.

[0050] As shown in Figure 3, the landing call buttons 111a provided on each control panel 111 are, for example, Each is provided on the wall 301 near the door 110a. The cage 101 is located on The display units 111b that show floor levels, etc., are, for example, each located on the wall surface above the door 110a. It is installed in 302, for example. The display unit 111b indicates, for example, the floor where the elevator car 101 can stop. The display unit 111b shows the floor level on which the cage 101 is located. Only the floor on which it is located may be displayed. Elevator 100 is not equipped with a display unit 111b. It's fine.

[0051] The control board 111c, like the control board for the operation panel 101b, is useful for the elevator 100. Each time an input operation is received from a user or other person to the boarding area call button 111a, the input It generates a call signal corresponding to the force operation and outputs the generated call signal to the control panel 106.

[0052] In this embodiment, among the various parts of the elevator 100, for example, control Each part outputs a signal to the control panel 106, the so-called "upstream signal," and this invention relates to This configuration can be realized. In addition, in this embodiment, elevator 10 Among the various parts that 0 has, for example, the CPU (Central Processor) of the control panel 106 It operates according to the signal output from the ssing unit, the so-called "downlink signal". The components according to this invention can be realized through these various parts.

[0053] Specifically, the components are realized, for example, by the drive mechanism of the elevator 100. This is possible. More specifically, the drive mechanism of the elevator 100 is, for example, the hoisting machine 104 This can be achieved by an electromagnetic brake 107, a motor that opens and closes the door 101a, etc. The drive mechanism of this elevator 100 is controlled by the downward signal output from the control panel 106. It operates according to the specifications. Furthermore, the drive mechanism of elevator 100 is also controlled by control panel 10 It may also be a device that outputs an uplink signal to 6.

[0054] Furthermore, the components are implemented, for example, by the control mechanism of the elevator landing 110. It can be expressed. Specifically, the control mechanism of the landing 110 of elevator 100 is, for example For example, this is achieved by the control panel 111 (control board 111c) installed at each boarding area 110. This is possible. Furthermore, the components are implemented by the control mechanism of the elevator car 101 of the elevator 100. It can be expressed. Specifically, the control mechanism of the elevator car 101 of elevator 100 is, even This can be achieved by the control panel 101b provided on the cage 101.

[0055] Furthermore, the components can be realized, for example, by the sensor mechanism of the elevator 100. Yes, it is possible. Specifically, the sensor mechanism of elevator 100 includes, for example, limit switch 1 09. This can be achieved by various sensors such as door opening / closing sensors. S outputs an upward signal to the control panel 106.

[0056] In this embodiment, the replacement work method according to the present invention is used to replace the control panel (old control panel) This section explains how to replace the old control panel 106 with a new control panel. It has the same configuration as the 6 and is equipped with a box-shaped iron casing that houses each part that makes up the new control panel. (See Figure 8D).

[0057] (An example of the configuration of the new control panel) Next, we will explain the configuration of the new control panel. Figure 4 shows an example of the configuration of the new control panel. This is a diagram. As shown in Figure 4, the new control panel 400 includes a CPU 401, a memory 402, and It is equipped with a power terminal 403, an output terminal 404, and a communication I / F (Interface) 405. (Diagrams are omitted for all of these.) The parts 401 to 405 of the new control panel 400 are: They are connected by bus 406.

[0058] The CPU 401 of the new control panel 400 controls the multiple components of the elevator 100. It controls the entire elevator 100. Memory 402 of the new control panel 400 is the elevator The Beta 100 stores programs and data used to control its various components. The CPU 401, for example, is based on an uplink signal input via input terminal 403. Then, it performs calculations using programs and data stored in memory 402. Furthermore, the CPU 401 outputs a signal based on the result of the calculation process via the output terminal 404. The output is then sent to the corresponding component.

[0059] Specifically, the CPU 401, for example, outputs from the control board for the control panel 101b. Based on the call signal, the hoisting machine 104, the electromagnetic brake 107 and the door 101a, Generates a downlink control signal for each component, such as the motor that opens and closes 110a. The control downlink signal is output to each corresponding component.

[0060] Furthermore, the CPU 401 controls, for example, the hoisting machine 104 (encoder) and the brake sensor. Based on the upward signals output from each component, such as the door opening / closing sensor, each component operates normally. It determines whether or not it was created. Also, the CPU of the new control panel 400 is, for example, the operation panel 101b A control board for the cage 101 is provided with a control signal including a floor signal indicating the floor on which the cage 101 is located. The system outputs a number, and on the control panel 101b, it displays the floor level where the cage 101 is located and its direction of movement (whether it is rising or not). Display information such as whether the price is falling.

[0061] The input terminal 403 of the new control panel 400 connects to multiple components of the elevator 100 and control A hardware interface that connects the CPU of the control panel 106, and outputs from each component It accepts the input of the signal being forced and outputs the received signal to the CPU of the new control panel 400. The input terminal 403 is used, for example, to connect each component of the elevator 100 to the new control panel 400. Conversely, it accepts input for the uplink signal to be output.

[0062] Specifically, the input terminal 403 is connected to, for example, the control board for the control panel 101b or the control panel 101 It accepts the input of the call signal output from the control board for b. Also, the input of the new control panel 400 The power terminal 403 accepts, for example, the input of a signal output from an encoder. Input terminal 403 can be used for, for example, a limit switch 109, a door opening / closing sensor, or an electromagnetic brake 1 Signals output from various sensors, such as brake sensors, whose output changes according to the operation of 07. It accepts input. Brake sensors include, for example, microswitches and photoelectric sensors. This can be achieved by [method].

[0063] The output terminal 404 of the new control panel 400 is connected to multiple components of the elevator 100 and the new control panel 404. A hardware interface connecting the control panel 400 to the CPU 401, and a new control The downstream signal output from the CPU 401 of the control panel 400 is output to the corresponding component. Output terminal 404 is, for example, a control generated by the CPU 401 of the new control panel 400. The downward signal for the hoisting machine 104, the electromagnetic brake 107, the door 101a of the cage 101 and the platform 1 This outputs power to the motor that opens and closes the 10 doors 110a.

[0064] The communication interface 405 connects to the management server computer via a network such as the internet. It is connected to the computer (illustrations are omitted). Specifically, the communication I / F405 is For example, mobile phone lines (for example, LTE (Long Term Evolution) ), wireless communication such as PHS (Personal Handy-phone System) The communication interface can be used to realize the communication I / F405. The F405 uses wired communication interfaces such as modems and LAN adapters. It may also be achieved through [some means].

[0065] The management server computer is located at the location where the elevator 100 to be monitored is installed. Unlike the elevator 100, it is installed in a remote location far from where the elevator 100 is installed. The management server computer is responsible for the maintenance and management of elevator 100, for example. It can be installed by property management companies, etc.

[0066] The communication interface 405 receives the alarm signal output from the CPU 401 from the management server computer. The signal is sent to the computer. The alarm signal is used, for example, to detect a fault in elevator 100. If this occurs, the operating mode of elevator 100 changes, etc., and the CPU 401 communicates The output is sent to the management server computer via the signal interface 405.

[0067] Furthermore, the communication I / F405 receives instructions for executing diagnostic operations from the management server computer. It receives various instructions such as signals and outputs them to the CPU 401. Diagnostic operations are performed from the new control panel 400. The elevator 100 receives signals to operate each of its components in a predetermined sequence. A signal is output, and a new signal is generated indicating whether or not each part operated normally according to the output signal. This is achieved by outputting from the control panel 400. The management server computer, for example, For example, it outputs instructions to perform diagnostic actions periodically (for instance, at the end of each month).

[0068] The new control panel 400 and the management server computer are connected via the communication I / F 405 and a telephone line. By connecting via the internet rather than public voice networks, natural disasters such as earthquakes can be prevented. Due to the telephone lines becoming overloaded during emergencies such as the occurrence of an incident, the situation of elevator 100 This avoids delays in understanding the data. This allows the management server computer to be used In a situation where the elevator 100 is being remotely monitored, the operation of the elevator 100 We can respond quickly if a problem occurs.

[0069] The new control panel 400 is further connected to the public voice network via the communication I / F 405. This is also acceptable. Public voice networks include fixed-line telephone networks (public switched telephone networks) and mobile phone networks. The voice network consists of subscriber line exchanges that house telephone lines, relay exchanges that bundle subscriber line exchanges, and other... It consists of multiple exchanges, such as gateway exchanges that connect to the vendor's telephone network, which are not shown in the diagram. The public voice network is a well-known technology, so its explanation will be omitted. New control panel 400 By connecting to the public voice network via the communication I / F405, the intercom terminal Voice communication between device 205 and the management center can be achieved.

[0070] In this case, the new control panel 400 uses an LTE board (LTE module) to collect data. Communication may be performed. That is, the LTE board may be used for both data communication and voice communication. It can also be used for communication. By using LTE for communication, the quality of communication can be ensured. It is possible to use LTE. Also, since the installation location of elevator 100 is fixed, By performing this communication, the installation location of elevator 100 can be determined. .

[0071] The components 401-405 of the new control panel 400 are mounted on one or more circuit boards. It is housed in a box-shaped iron casing (see Figure 8D). The new control panel 400 is equipped with Each of the parts 401-405 is a PLC (Programmable Logic Controller). It may also take the form of an oller. The enclosure may further include relays and inverters. , circuit breakers, fuses, transformers, electromagnetic switches, timers, counters, etc., elevator The various parts related to the control of the elevator are housed here. The lower part of the housing of the new control panel 400 is the elevator An opening (new control panel 4) for routing cables connected to the components of 100 into the enclosure. A lower opening (00) is provided.

[0072] The new control panel 400 accepts signal inputs to the new control panel 400 and the input signals It outputs a signal based on that. The new control panel 400 uses a different program than the control panel 106. It operates according to the program. The new control panel 400 uses machine language, that is, An electrical signal that can be represented by two values, "0" and "1", and which the control panel 106 can understand. Understand signals other than the "number" signal.

[0073] Furthermore, the new control panel 400 controls multiple components controlled by the control panel 106, A signal that has the same meaning as the signal output by the control panel 106, and is a signal that the component can understand. It outputs a different signal. Specifically, the new control panel 400, for example, is connected to the old control panel 106. The type of programming language used to write the control program for the control process is different from the type of programming language used to write the control program. It outputs signals based on a control program written in a programming language.

[0074] Alternatively, more specifically, the new control panel 400 can, for example, be controlled by the old control panel 106. The type of programming language used to write the control program is the same type of programming language. A control program described therein, which is a control program related to control by the old control panel 106 It also outputs signals based on a control program written in a description method different from the description method of the M. That is also acceptable.

[0075] Furthermore, the new control panel 400 controls multiple components that are controlled by the old control panel 106. The old control panel 106 outputs signals that the component can understand, This may also be the case. In other words, the new control panel 400 controls the control performed by the old control panel 106. The programming language used to write your program is of the same type and written in the same style. It may also output signals based on a control program.

[0076] The control program for control using the new control panel 400 is designed for advanced control. Performance improvements have progressed, and the control program used for control by the old control panel 106 has become more complex. They are often present. For this reason, the multiple components of elevator 100 are old control panel 10 Even if you can understand the signal output by unit 6, you may not be able to understand the signal output by the new control panel 400. be.

[0077] For these reasons, when replacing conventional control panels, in addition to the old control panel 106, Multiple components controlled by the control panel 106 (in particular, the signals output by the new control panel 400) They were replacing the components that could not be fixed. In conventional replacement work, the old control panel 106 and all of its components are replaced. The elevator could not be operated until it was replaced, which prolonged the construction period. This will cause inconvenience to elevator users as the period during which the elevator will be unusable will be extended. There was a problem with parts breaking. Also, because there were many parts to replace, the construction period was extended. There was a problem with the heavy burden on workers involved in the replacement work.

[0078] In the replacement work of this embodiment, the signals output by the new control panel 400 cannot be understood. If components exist, a signal conversion device will be installed in addition to the new control panel 400. The switching device receives the signal output by the new control panel 400 and the multiple controls that were controlled by the old control panel 106. The numerical components are converted into signals that can be understood and output to the respective components. The device receives signals output by multiple components that were previously controlled by the old control panel 106, and the new control panel The signal is converted into a format that the control panel 400 can understand and output to the new control panel 400.

[0079] (Functional configuration of a signal converter) Next, the functional configuration of the signal conversion device will be explained. Figure 5 shows the functional configuration of the signal conversion device. This is a block diagram showing the configuration. In Figure 5, each function of the signal conversion device 500 is located on the component side. The input section 501, the input section 502 on the new control panel 400 side, the signal conversion section 503, and the new control panel This is achieved by the output unit 504 on the 400 side and the output unit 505 on the component side.

[0080] The input section 501 on the component side is where each component of the elevator 100 outputs to the control panel 106. It accepts an uplink signal input. The input section 501 on the component side is provided, for example, for each component. This can be achieved by multiple input terminals 401 (connection terminals). New control panel 40 The input section 502 on side 0 is the down line that the new control panel 400 outputs to each component of the elevator 100. It accepts signal input. The input section 502 on the new control panel 400 side is, for example, the new control panel 40 This can be achieved by the input terminal 403 (connection terminal) provided in response to 0.

[0081] The signal conversion unit 503 converts the upstream signal received by the input unit 501 on the component side to the upstream signal. This signal has the same meaning as the previous signal, but it is converted into a different signal that the new control panel 400 can understand. Furthermore, the signal conversion unit 503 receives the downlink signal from the input unit 502 on the new control panel 400 side. This is a signal with the same meaning as the said downlink signal, and each component that is the output destination of the said downlink signal is responsible for Convert it into another signal that can be interpreted.

[0082] Specifically, the signal conversion unit 503 includes, for example, a memory that stores a signal conversion program and A processor consists of a CPU and other components that execute programs stored in memory. This allows the function to be realized. Alternatively, the signal conversion unit 503 can, for example, FP GA (Field-Programmable Gate Array) and signal conversion specialized ASIC for Application Specific Integrated Circuits (C) This functionality may be implemented using tools such as ircuit.

[0083] The output section 504 on the new control panel 400 is understood by the new control panel 400 via the signal conversion section 503. The upstream signal, converted to another possible signal, is output to the new control panel 400. (New control panel 400 side) The output section 504 is connected to the output terminal 404 (connection terminal) provided in accordance with the new control panel 400. Therefore, this can be achieved. The output unit 505 on the component side is each converted by the signal conversion unit 503. The downstream signal, converted into another signal that the components can understand, is output to the corresponding components. The output section 505 on the component side has multiple output terminals 404 (connection terminals) provided for each component. Therefore, it can be achieved.

[0084] The components 501 to 505 of the signal conversion device 500 are connected to the control panel 106 and the new control panel 400. Similarly, it is housed in a box-shaped iron casing (see Figure 8D). Signal converter 50 The enclosure for unit 0 is separate from the enclosures for control panel 106 and the new control panel 400. Signal conversion device The lower part of the 500 enclosure houses the cables connected to each component of the elevator 100. An opening (the lower opening of the signal converter 500) is provided for routing the device inside the body. The components of the signal conversion device 500 may be housed within the casing of the new control panel 400. In other words, the signal converter 500 and the new control panel 400 may share the same housing. .

[0085] The new control panel 400, which controls the elevator 100 using new technology, is the same as the old control panel 106. Although it has the same configuration, compared to the old control panel 106, in addition to improved performance, the casing (that is In some cases, the external dimensions of the new control panel 400 are becoming smaller. When replacing control panel 0 with control panel 106, the size of the new control panel 400 (and its casing) is different from that of the old control panel 10. It will be smaller than the size of the 6 (casing).

[0086] If the old control panel 106 is installed in the machine room, connect it to each component of the elevator 100. The cables were routed through a cable pit in the floor of the machine room, and then to the old control panel 10 It connects to 6. The cable pit is a recessed groove in the floor of the machine room and is covered with a lid. (See Figures 8A to 8D).

[0087] The cable routed through the cable pit is located at the end of the old control panel 106 on the cable pit side. It is pulled out onto the floor through a floor opening (see Figure 8B) and connected to the old control panel 106. It continues. Below the floor opening, there is a square recess from the floor surface. Cable pits and floor openings are For example, a machine that forms a groove for a cable pit and a square shape for a floor opening. It is formed by pouring concrete onto the floor of the machine room.

[0088] A floor opening is defined as a length on one side of the floor that is greater than the width of the cable pit. It is rectangular or square in shape. Generally, the length of the side of the floor opening is the same as that of the old control panel 106 It is shaped to match the size of the lower end of the enclosure. For this reason, the control panel 106 is made to match the size of the old control panel When replacing the 106 with the new control panel 400, which is smaller in size, simply install the new control panel on top of the floor opening. When the 400 floor panel is installed, a portion of the floor opening remains open. If there are unintentional openings in the surface, part of the cable will be exposed, which is undesirable from a safety standpoint. Furthermore, the footing for workers performing maintenance on control panels may become poor, and workers may be injured. It is undesirable because there is a risk of people tripping or losing their footing while passing through.

[0089] In conventional control panel replacement work, in such cases, the new panel must be sized to match the old control panel 106. Some of the floor openings and cable pits that were previously provided have been resized to fit the new 400 control panel. The area was then backfilled with concrete, etc. During the backfilling process, the laid cables were used. Remove the bulldozer, backfill with concrete, and once the concrete has completely hardened, then re-install the cable. The work of laying the ropes must be carried out, which increases the burden on workers, and the elevator The period during which elevator 100 was unavailable was extended, causing inconvenience to elevator 100 users. I had taken the bait.

[0090] In contrast, according to the replacement work method of this embodiment, a base mount is used. This makes backfilling work unnecessary. Below are embodiments of this invention. Let me explain about mounting.

[0091] (An example of a base mount structure) Next, the structure of the base mount according to the embodiment of this invention will be described. Figure 6 This is an explanatory diagram showing an example of the structure of a base mount. As shown in Figure 6, the base mount The T600 consists of a support plate 601, an opening 602 for the new control panel, legs 603, and a control panel fixing bolt. A through hole 604 for the torch, an opening 605 for the conversion device, and a through hole 606 for the conversion device fixing bolt, It is equipped with through holes 607 for base mount fixing bolts.

[0092] The support plate 601 has a roughly rectangular plate shape. The outer edge shape of the support plate 601 is such that it extends from the floor opening. It is also large. The support plate 601 can be made of, for example, a steel plate. New control The panel opening 602 penetrates the support plate 601 in the thickness direction and is smaller than the bottom opening of the new control panel 400. The opening 602 for the new control panel is made of, for example, a steel plate that will serve as the support plate 601. It can be formed by punching.

[0093] The leg portion 603 is provided on one side of the support plate 601. The leg portion 603 is attached to the base mount When the to 600 is installed on the floor surface, it is positioned closer to the floor surface than the support plate 601, The lower end of the control panel 400 is set a predetermined distance away from the floor opening (floor height). Specifically, the legs 603 is, for example, formed from a steel plate or the like into a rectangular tube shape, and one wall surface of the rectangular tube is welded or otherwise It is constructed by fixing it to one side of the support plate 601.

[0094] By making the leg portion 603 rectangular tube-shaped, the stability and strength of the leg portion 603 are ensured while This allows for weight reduction of the base mount 600. The leg portion 603 is made of, for example, steel plate. Even if it is provided integrally with the support plate 601 by punching out angles and bending, stomach.

[0095] The through-hole 604 for the control panel fixing bolt is the fixing position of the new control panel 400 on the support plate 601. It is provided in a position corresponding to the control panel fixing bolts 604 is located on the support plate 601. It penetrates in the thickness direction. Specifically, the through-hole 604 for the control panel fixing bolt is, for example, a newly manufactured With the control panel 400 installed on the base mount 600, the new control panel 400 Positions that overlap with pre-installed fixing bolt holes (positions opposite each other in the vertical direction) It is located at [location].

[0096] The opening 605 for the conversion device penetrates the support plate 601 in the thickness direction and is located below the signal conversion device 500. The opening is smaller than the surface opening. The opening 605 for the conversion device is continuous with the opening 602 for the new control panel. It is not, and is an opening separate from the new control panel opening 602. Through-hole for conversion device fixing bolt. 606 is provided on the support plate 601 and is positioned according to the fixed position of the signal conversion device 500 (lead It is provided at positions opposite to each other along the perpendicular direction. The through hole 606 for the conversion device fixing bolt is The support plate 601 penetrates through it in the thickness direction.

[0097] Through holes 607 for base mount fixing bolts are provided in the leg portion 603. The through-hole 607 for the mounting bolt is located at the connection point with the support plate 601 on the leg portion 603. On the opposite side, the plate surface located in a position facing the support plate 601 penetrates in the thickness direction. The through-hole 607 for the base mount fixing bolt is located on the floor surface of the base mount 600. When placed in position, it is positioned opposite the periphery of the floor opening.

[0098] The base mount 600 further includes a vibration-damping member for the control panel (not shown in the figure). Alternatively, the vibration-damping member for the control panel is provided on the periphery of the new control panel opening 602 in the support plate 601. Multiple vibration-damping members for the control panel are scattered around the periphery of the new control panel opening 602. It may be provided, and may be provided continuously around the periphery of the new control panel opening 602. That's fine.

[0099] Furthermore, the base mount 600 is equipped with a vibration-damping member for the conversion device (not shown). It may be. The vibration-damping member for the conversion device is located in the opening 605 for the conversion device in the support plate 601. It is provided on the periphery. The vibration-damping members for the conversion device are scattered on the periphery of the opening 605 for the conversion device. Multiple such devices may be provided, and they may be arranged in a continuous manner to surround the periphery of the conversion device opening 605. It may be provided.

[0100] Vibration-damping components for control panels and converters are formed from rubber or elastomer. This is possible. Specifically, vibration-damping materials for control panels include, for example, natural rubber, urethane rubber, and natural rubber. Nitrile rubber, chloroprene rubber, butyl rubber, styrene-butadiene rubber, silicone It can be formed using various known materials such as rubber.

[0101] (Control panel replacement procedure) Next, the method for replacing a control panel according to the embodiment of this invention, Let's explain the steps in order. Figure 7 is a flowchart showing the procedure for replacing the control panel. Figures 8A~ Figure 8D is an explanatory diagram showing an example of the replacement process in a control panel replacement project.

[0102] As shown in Figure 7, when replacing the control panel, first, the cable from the old control panel 106 Remove (step S701). In step S701, as shown in Figure 8A, Remove all cables connected to the old control panel 106 that is currently in place. As described above, the cable pit is provided in a recessed area below the floor surface 801 of the machine room. The cable is routed to each component of the elevator 100 via the T802, etc., and connected to each of those components. It is done. Cable pit 802 is covered with cover 80 during normal operation when no construction or inspection is being carried out. It is closed by 2a. The cover 802a is positioned at the same height as the floor surface 801. Yes, they are.

[0103] Next, the old control panel 106 is removed (step S702). The old control panel 106 is installed above the floor opening 803, covering the floor opening 803. Move it from above the floor opening 803. As a result, as shown in Figure 8B, the floor opening 8 03 is opened. Cable 804, removed from the old control panel 106, goes to cable pit 8. Leave it in place, routed through 02 and the floor opening 803. The floor opening 803 is shown in Figure As shown in 8A, etc., it is provided to match the size of the enclosure 805 of the old control panel 106. .

[0104] Next, install the base mount 600 on the floor surface 801 (step S703). In the S703, as shown in Figure 8C, the support plate 60 in the base mount 600 1 installs the base mount 600 on the floor surface 801 with the base mount 600 facing the floor opening 803. Furthermore, the base mount 600 is fixed to the floor surface 801 using bolts or the like. Specifically, For example, insert a bolt into the through hole 607 for the base mount fixing bolt, and then place the bolt on the floor By driving (screwing) the base mount 600 into the periphery of the surface opening 803, the base mount 600 is attached to the floor surface. It can be fixed to 801.

[0105] Then, the new control panel 400 is installed on top of the base mount 600 which is installed on the floor surface 801. (Step S704). In step S704, as shown in Figure 8D, the new control panel The bottom opening of the 400 enclosure 806 faces the new control panel opening 602, The new control panel 400 is installed on top of mount 600. Also, in step S704 The new control panel 400 has pre-installed fixing bolt holes (not shown in the diagram), and The through-holes 604 for the control panel fixing bolts provided in the mount 600 are aligned in the vertical direction. The new control panel 400 is installed on top of the base mount 600, facing it.

[0106] Furthermore, in step S704, the new control panel 400 is pre-installed with a fixed Bolt holes and through holes 604 for control panel fixing bolts are used for control panel fixing bolts (not shown in the diagram). Insert the bolt and the head of the control panel fixing bolt and the nut that is screwed onto the control panel fixing bolt. Therefore, the new control panel 400 is sandwiched between the housing 806 and the base mount 600. Tighten the bolts and nuts that secure the control panel. This will mount the new control panel 400 to the base. It can be fixed at 600.

[0107] Furthermore, if the installation of the signal converter 500 is required, a base mount installed on the floor surface 801 Install the signal converter 500 on top of the 600 (step S705). Step S70 In 5, as shown in Figure 8D, the lower opening of the signal converter 500 is the conversion device opening. The signal converter 500 is installed on the base mount 600, facing 605. In addition, in step S705, the signal converter 500 is provided with Bolt holes for fixing (not shown in the diagram) and a conversion device mounting bracket provided on the base mount 600 The through-hole 606 for the fixed bolt and the base mount 6 are positioned opposite each other in the vertical direction. A signal converter 500 is installed on top of 00.

[0108] Furthermore, in step S705, the signal converter 500 is fixed in advance Bolt holes for the conversion device and through holes 606 for the conversion device fixing bolts (not shown) (abbreviated) is inserted and screwed into the head of the conversion device fixing bolt and the conversion device fixing bolt. The nut secures the housing 807 and base mount 600 of the signal conversion device 500. The conversion device fixing bolts and nuts are tightened so that they are sandwiched in place. This secures the signal conversion device. The 500 can be fixed to the base mount 600.

[0109] The order in which the processes in step S704 and step S705 are executed is reversed. Alternatively, a signal converter 5 can be placed on a base mount 600 installed on the floor surface 801. The new control panel 400 may be installed after the 00 is installed. Also, the installation of the signal conversion device 500 If placement is not required, the process in step S705 may be omitted.

[0110] If the installation of the signal converter 500 is not required, the converter opening 605 is used as the converter opening 6 The opening may be closed by covering it with a steel plate larger than 05. In this case, the opening for the conversion device. The steel plate closing 605 has a through hole 606 for the conversion device fixing bolt, in a position that overlaps with the conversion device For inserting bolts to fix the steel plate that closes the mounting opening 605 to the base mount 600. A through hole may be provided for fixing the steel plate that closes the opening 605 for this conversion device. The number of through holes provided may be less than the number of through holes 606 for the conversion device fixing bolts. The steel plate that closes the opening 605 is lighter than the signal converter 500, so bolts are inserted. The number of through holes for insertion is to be less than the number of through holes 606 for fixing the conversion device bolts. This ensures that the steel plates are securely fixed and reduces the burden on workers involved in fixing the steel plates. It is possible.

[0111] Next, connect cable 804 (step S706). In step S706 This refers to the cable 804 that is routed from each component of the elevator to the floor opening 803. Of these, cable 804, which connects to the new control panel 400, is routed through the opening 602 for the new control panel to the base Pull it out from the top of mount 600 and connect it to the new control panel 400. Specifically, the new control panel 4 Cable 804, which connects to 00, is connected to input terminal 403 and output terminal 404 of the new control panel 400. Connect.

[0112] Furthermore, in step S706, from each component of the elevator to the floor opening 803 Of the cables 804 that are routed, cable 804 is connected to the signal converter 500. The signal conversion device is pulled out to the upper side of the base mount 600 through the opening 605 for the conversion device. It connects to the 500. Specifically, the cable 804 that connects to the signal converter 500 is the signal It is connected to the input section 501 and the output section 505 on the component side of the conversion device 500.

[0113] The base mount 600, with its legs 603, is positioned at the floor opening 803 (height of floor 801) and A space is secured between the support plate 601 and the new control panel 400 and the signal conversion device. Below the lower end of 500 and above the floor opening 803, there is a length corresponding to the leg portion 603. There is sufficient vertical space. Furthermore, there is space between the leg sections 603. Therefore, the worker enters the floor opening 803 through the space secured beneath the support plate 601. It was easy to reach in and grab cable 804, and then connect the grabbed cable 804 to the new control panel 400 or signal The new control panel 400 and the housing 806 of the signal converter 500 are accessible through the opening on the bottom of the converter 500. This allows for routing and other operations within the 807. Compared to the case where the lower end of the signal converter 500 is directly fixed to the floor surface 801, The process of connecting the Bull 804 can be done easily and quickly, reducing the burden on the worker. It is possible.

[0114] Furthermore, in step S706, a signal is transmitted between the signal converter 500 and the new control panel 400. Connect the cable 804 that transmits and receives signals. Specifically, for example, the input of the new control panel 400. The power terminal is connected to the output unit 504 on the new control panel 400. Specifically, for example... The output terminal 404 of the new control panel 400 is connected to the input section 502 on the new control panel 400.

[0115] After that, a functional check was performed (step S707), and elevator 100 was confirmed to be working correctly. A decision is made on whether or not to do so (step S708). In step S707, for example, Based on the upward signals input from each component to the new control panel 400 via the signal conversion device 500 , the operation of the new control panel 400 is confirmed. Specifically, for example, the operation panel 101 of the car 101 b is operated to check whether the car 101 ascends or descends to the designated floor .

[0116] Also, in step S707, for example, the operation of each component according to the downward signals input from the new control panel 400 via the signal conversion device 50 0 is confirmed. Specifically, for example, the operation panel 111 provided at the landing 110 is operated to generate a call for the corresponding floor in response to the operation, and it is checked whether the car 101 moves to the floor .

[0117] In step S708, based on the confirmation result in step S707, whether the new control panel 400 operates or all components operate based on the upward signals input from each component to the new control panel 400 via the signal conversion device 500, and whether it operates according to the downward signals input from the new control panel 400 via the signal conversion device 500 , etc., the result is based on, and it is determined whether the elevator 100 operates normally . . .

[0118] According to the specifications of the new control panel 400, by connecting the signal conversion device 50 0 between each component and the new control panel 400, even when replacing the control panel 106 with the new control panel 400, the new control panel 400 can understand the signals output by the component . Also, according to the specifications of the new control panel 400, by connecting the signal conversion device 500 between each component and the new control panel 400 , even when replacing the control panel 106 with the new control panel 400, the component can understand the signals output by the new control panel 400 and operate accurately . .

[0119] Thus, according to the specifications of the new control panel 400, by connecting the signal conversion device 500 between each component and the new control panel 400, even if a part of the component to be replaced is a component that the new control panel 400 cannot directly control, such as a component of another manufacturer or a component with different specifications, the replacement of the control panel can be carried out without replacing the component. Thus, the control panel can be replaced without replacing all components, thereby reducing the burden on the operator and shortening the working time, and suppressing the cost of one construction project.

[0120] In step S708, when the elevator 100 operates normally (step S7 08: Yes), the replacement work of the control panel 106 is completed. On the other hand, in step S708 when the elevator 100 does not operate normally (step S708: No), connection confirmation is performed (step S709), and the process proceeds to step S707 to perform the operation confirmation again. In step S709, for example, the connection state between the component that did not operate according to the signal output from the new control panel 400 and the new control panel 400 is confirmed, or the connection state is adjusted.

[0121] The processes of step S707, step S708, and step S709 are repeated until it is confirmed that the new control panel 400, the signal conversion device 500, and each corresponding component operate normally. Thereby, the safety of the elevator users can be ensured.

[0122] Maintenance and management of elevator 100 include, for example, the control panel 106 of elevator 100 and point Based on the communication results with the inspection terminal, the operation history of elevator 100 to be managed for maintenance is recorded. This involves regularly checking the vehicle and replacing parts based on the operational history that has been checked. This is thus achieved. Furthermore, maintenance and management of the elevator 100 are carried out, for example, by the control panel 106 and It communicates periodically with the management server computer to perform diagnostic operations and diagnostic actions This is achieved through component replacement and other measures taken in response to the results of the work.

[0123] In the maintenance and management of such elevators 100, conventionally, for example, each component is dedicated In the elevator 100 controlled by the ASIC, some components are replaced with new components. If you wish to replace it, it is assumed that the new component cannot be controlled by the existing ASIC. In this situation, the new components are not limited to those that can be controlled by the existing ASIC. It gets destroyed.

[0124] More specifically, for example, the hoisting machine 104 controlled by a dedicated ASIC can be replaced If this is the case, another hoisting machine 104 with lower power consumption and higher output than the existing hoisting machine 104. Even if one exists, it may be replaced with another hoisting machine 104 due to limitations imposed by the existing ASIC. This is not possible. Therefore, the person in charge of managing elevator 100 controls it using the existing ASIC. Either replace it with a suitable hoisting machine 104, or carry out a renewal including the existing ASIC. They were forced to choose one of the following, and the maintenance and management of elevator 100 was carried out by the person in charge of management, etc. There was a situation where the degree of freedom was low.

[0125] Furthermore, communication between the control panel 106 and the inspection terminal for the maintenance and management of the elevator 100, Alternatively, communication between the control panel 106 and the management server computer often uses signals specific to each elevator manufacturer. Therefore, there has been a situation where it is difficult for an independent elevator maintenance service company, independent of the manufacturer or an elevator management company (hereinafter appropriately referred to as "manufacturer, etc.") in partnership with the manufacturer, to perform maintenance management. In the current situation where communication using signals specific to each manufacturer is performed during elevator maintenance management, new components replacing existing components (old components) must be selected within the range specified by the manufacturer, etc. for each elevator 100. As a result, there has been a situation where the freedom of maintenance management by the elevator 100 management staff, etc. is low. In addition, in the current situation where communication using signals specific to each manufacturer is performed, it is easy for the manufacturer, etc. for each elevator 100 to uniquely set the cost required for elevator maintenance management (maintenance management cost).

[0126] Consequently, there has been a situation where it is difficult for the elevator 100 management staff, etc. to reduce the maintenance management cost they bear. The safety and sense of security of elevator users tend to increase as the frequency of elevator maintenance inspections increases. On the other hand, in the above situation, if the frequency of maintenance inspections is suppressed to the minimum stipulated by the guidelines of the Ministry of Land, Infrastructure, Transport and Tourism or a frequency close to it in order to reduce the maintenance management cost, it becomes difficult to achieve both cost reduction in maintenance management and improvement in the safety of elevator users.

[0127] In addition, in the current situation where communication using signals specific to each manufacturer is performed, it is easy for the manufacturer, etc. for each elevator 100 to uniquely set the cost required for elevator maintenance management (maintenance management cost). Consequently, there has been a situation where it is difficult for the elevator 100 management staff, etc. to reduce the maintenance management cost they bear.

[0129] In contrast, according to the control panel replacement method of this embodiment, as described above, By connecting the signal conversion device 500 between the control panel 400 and the new components, the existing components and the new components Even when both conditions are present, the elevator 100 can be operated. The replacement work from existing components to new components can be carried out by distributing the work to each component. And as a result, a part of the component operates the elevator 100 during each replacement operation. It can be done.

[0130] In the embodiment described above, the CPU 401 of the new control panel 400 is used to change the signal The elevator 100 controls each component by performing various processes such as replacement processing. As explained above, the control of elevator 100 is implemented using CPU 401. Not limited to that. Instead of the CPU401, for example, a cluster for a specific application that integrates multiple circuits. Examples include ASICs, which are integrated circuits, and FPGAs, which are integrated circuits whose configuration can be arbitrarily set after manufacturing. The control of the elevator 100 may be implemented using this method.

[0131] In the above-described embodiment, a rope-type elevator 100 will be explained. However, the elevator 100 according to this invention is not limited to a rope-type elevator 100. No. Instead of the rope-type elevator 100, or the rope-type elevator In addition to -100, for example, a hydraulic elevator 100 may also be used.

[0132] Furthermore, in the above-described embodiment, the old control panel 106 equipped with a communication function is replaced with the new control panel 4 The replacement work method for replacing with 00 has been explained, but the old control panel 106 has a communication function This is not limited to those that have been installed. For example, for reasons such as not anticipating remote monitoring at the time of installation. The old control panel 106, which lacked communication capabilities and required a separate communication device to be connected after installation, was redesigned. Even when replacing with control panel 400, the control panel replacement method according to this invention shall be applied. This is possible. In this case, for example, the old control panel 106 and communication device can be moved to the new control panel 40. Replace it with 0.

[0133] As explained above, the method for replacing the control panel according to the embodiment of this invention is for elevators A method for replacing a control panel that controls multiple components of a motor 100, wherein the floor surface 80 The old control panel 106 installed at 1 was removed, and the old control panel was laid below the floor surface 801. A floor that guides the cable 804 connecting the control panel 106 and multiple components to the old control panel 106. The surface opening 803 is left open, and the support plate 60 has a plate shape with an outer edge shape larger than the floor surface opening 803. 1 penetrates the support plate 601 in the thickness direction and opens to a smaller size than the opening on the bottom surface of the new control panel 400. A base mount 600 equipped with a new control panel opening 602, and the support plate 601 having a floor opening The base mount 60 is installed on the floor 801 facing 803. The new control panel 400 is installed on top of the new control panel opening 602, and the cable 804 is routed through the floor opening.

[0136] Recent technological advancements have led to not only higher performance control panels but also miniaturization of control panels. The new control panel 106 was simply installed on top of the floor opening 803, which was made to match the size of the old control panel 106 enclosure. When the 400 platform is installed, a portion of the floor opening 803 remains open. In this case, The area near the control panel 400 is partially recessed, and part of the cable 804 is exposed. This can lead to damage to cable 804, and may also affect maintenance of the control panel. The footing for workers performing the work may become unstable, or workers may lose their footing when passing by. It is undesirable as it may cause people to trip or stumble.

[0137] As a countermeasure, a portion of the floor opening 803 was made of concrete to match the size of the new control panel 400. When backfilling with concrete, etc., the already laid cable 804 must be removed and the concrete Since the cable 804 must be laid again after the soil has dried, the burden on the workers is As the number of cases increases, the period during which elevators are unusable becomes longer, and elevator 1 This will cause inconvenience to users of 00.

[0138] Furthermore, it was designed to match the size of the older control panel 106, which is larger than the new control panel 400. If the new control panel 400 is simply installed on top of the floor opening 803, the installation of the new control panel 400 is not possible. As the situation stabilized, there was a risk that it would become difficult to ensure sufficient safety.

[0139] In contrast, according to the control panel replacement method of the embodiment of this invention, the old control panel Even the new control panel 400, which is different in size from the 106, can be installed stably, and after installation This ensures the aesthetic appearance of the area around the new control panel 400.

A signal conversion device 500 is installed to convert the signal to another signal, and among the multiple components, a new control panel 40 Cable 804, connected to a component that can understand the signal output by 0, is routed through a floor opening 803. The wires are routed and connected to the new control panel 400 via the opening 602 for the new control panel, and multiple components are connected Cable 804 connected to a component that cannot understand the signal output by the new control panel 400, The signal is routed from the floor opening 803 through the conversion device opening 605 to the signal converter 500 and connected. Furthermore, it is characterized by connecting the signal conversion device 500 and the new control panel 400.

[0142] According to the control panel replacement method of the embodiment of this invention, the new control panel 400 outputs A component that can understand the signals, and a component that cannot understand the signals output by the new control panel 400. Even in a state where both coexist, the new cable 8, which was essential in conventional replacement work, The elevator 100 can be operated without performing the installation work for 04. This will reduce the burden on workers and shorten the working time required for the replacement of control panels. It is possible.

[0143] Furthermore, according to the control panel replacement method of the embodiment of this invention, the new control panel 400 Components that cannot understand the signals output by the old control panel can understand the signals output by the new control panel 400. The elevator 100 can be operated by continuing to use it without replacing the parts. This will reduce the time required for replacing control panels.

[0144] Furthermore, the method for replacing the control panel according to the embodiment of this invention is a base mount 600 However, the new control panel 4 is provided on one side of the support plate 601 and installed on the floor surface 801.
