[0001] The present disclosure relates to a method for renovating an elevator.

Background Art

[0002] During the period of elevator renovation work in which at least some of the elevator equipment is replaced with new equipment, in principle, the elevator cannot be used . On the other hand, there is a customer demand to make the elevator available even during the renovation work.

[0003] Particularly in the case of residential elevators, not only in terms of construction costs, but also because the period during which the elevator cannot be used due to the construction becomes longer, there are many customers who hesitate to carry out the renovation work. In order to promote the renovation work, it is conceivable to adopt a method such as carrying out the work during the day and temporarily restoring the elevator to make it available at night when the work is not being carried out.

[0004] For example, Japanese Unexamined Patent Application Publication No. 2010-179998 (Patent Document 1) discloses a method for renovating an elevator including a step of providing operation by old equipment for passengers during the day and a process of enabling operation by new equipment at night.

Summary of the Invention

Problems to be Solved by the Invention

[0006] In elevator landing replacement work, it is necessary to replace the control panels for each floor, but in buildings with many floors, the work is divided into two or more days to replace the control panels for multiple floors. However, the above elevator renewal method does not take into account the need to operate the elevator during the replacement of control panels for multiple floors, and this point still needs to be considered.

[0007] This disclosure was made to solve the aforementioned problems, and its purpose is to provide an elevator renovation method that allows elevators to be used as much as possible even during renovation work. [Means for solving the problem]

[0008] The elevator renewal work method described herein is a method of renewal by replacing at least some of the elevator's equipment with new equipment. The elevator equipment includes multiple landing devices and a control device. The multiple landing devices are installed on each of the multiple floors on which the elevator car can stop and are operation panels for registering landing calls to call the car. The control device is capable of communicating with the multiple landing devices and controls the car to respond to landing calls. The replaced control device cannot communicate with the landing devices that were replaced among the multiple landing devices. The multiple floors include a first floor group and a second floor group. The elevator renovation work method includes the steps of replacing the control device, replacing the landing equipment installed on each floor of the first floor group among multiple landing equipment, operating the elevator by communicating the replaced control device with the landing equipment installed on each floor of the first floor group after the replacement, and, after operating the elevator, replacing the landing equipment installed on each floor of the second floor group among multiple landing equipment. [Effects of the Invention]

[0009] According to this disclosure, elevators can be used as much as possible even during renovation work. [Brief explanation of the drawing]

[0010] [Figure 1] This is a diagram showing the hardware configuration of an elevator. [Figure 2] This is a schematic diagram showing the structure of an elevator. [Figure 3] This is a diagram showing an example of an elevator landing. [Figure 4] This is a diagram showing an example of the interior of an elevator car. [Figure 5] This is a diagram illustrating an example of a renovation project schedule. [Figure 6] This diagram shows the stages of the renovation work. [Figure 7] This diagram illustrates an example of a renovation work schedule related to a modified model. [Figure 8] This figure shows a priority rule table related to variations. [Figure 9] This diagram shows the steps involved in the renovation work related to the modified form. [Modes for carrying out the invention]

[0011] The embodiments will be described below with reference to the drawings. In the following description, identical parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0012] Figure 1 shows an example of the hardware configuration of elevator 100. In this embodiment, the building in which elevator 100 is installed has N floors (for example, 16 floors), with the first floor being the main floor. The main floor is the main floor (entrance floor) where the building's entrances and exits are located, and is the floor with the highest volume of user traffic. In addition, one elevator car 10 (see Figure 2) of elevator 100 is installed in the building. Note that the number of cars 10 is not limited to one; multiple cars may be installed.

[0013] The elevator 100 includes, as landing equipment, a plurality of (for N floors) landing devices 230, control cables 21, etc. Further, the elevator 100 includes, as equipment other than the landing, a control panel 210, a hoisting machine 250, a car device 240, control cables 22, etc.

[0014] Hereinafter, a renewal construction method of the elevator 100 will be described. This renewal construction method is a method of renewing by replacing at least a part of the equipment of the elevator 100 with new equipment. In this renewal construction, first, the replacement work of the equipment other than the landing described above is performed, and then the replacement work of the landing equipment is performed. In the renewal construction, it may be possible to replace some of the equipment (electrical equipment) as necessary, or to replace all of the equipment. For example, the car 10 and the hoisting machine 250 may or may not be replaced according to the customer's request.

[0015] In the replacement work of the landing equipment, the work is carried out in a plurality of steps. In order to ensure the convenience of users (passengers), the elevator 100 is configured to be available between the works of these plurality of steps. Hereinafter, each device will be described.

[0016] The control panel 210 includes a control device 212. The control device 212 is a control board that controls an elevator equipment group. The elevator equipment group includes a plurality of landing devices 230, a hoisting machine 250 and a car device 240, various sensors and various switches used in the elevator 100, etc.

[0017] The hoisting machine 250 is a motor that drives to raise and lower the car 10 of the elevator 100. The car device 240 is various equipment installed in the car 10 and includes a car operation panel 50 (Fig. 4). The car operation panel 50 is an operation panel including a destination floor button for registering a car call (destination floor).

[0018] The plurality (N floors) of landing devices 230 are various devices installed at each landing, and include a plurality (N floors) of landing operation panels 70 (Fig. 3). The landing operation panel 70 is one aspect of the landing devices. The plurality of landing operation panels 70 are installed on each of the plurality of floors (1st floor to Nth floor) where the car 10 of the elevator 100 can stop, and is an operation panel including a landing button for registering a landing call to call the car 10.

[0019] The control device 212 can communicate with the plurality (N floors) of landing operation panels 70, and controls the car 10 to respond to the landing call. Further, the control device 212 can communicate with the car operation panel 50, and controls the car 10 to respond to the car call.

[0020] The control device 212 is connected to the landing devices 230 on each floor, various sensors, various switches, etc. via a control cable 21 bundling a plurality of signal lines. Further, the control device 212 is connected to the hoist 250 and the car device 240 of the No. 1 machine, various sensors, various switches, etc. via a control cable 22 bundling a plurality of signal lines.

[0021] The control device 212 includes a processor, a memory, and a communication interface. The processor is a CPU (Central Processing Unit). The memory is, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). These are communicably connected to each other via a bus.

[0022] The ROM stores a program of management software for controlling the elevator device group. The CPU reads the program stored in the ROM into the RAM and executes it to control the elevator device group. The RAM serves as a work area when the CPU executes the program, and temporarily stores programs, data when executing programs, etc.

[0023] The control device 212 is configured to communicate with elevator equipment such as the landing device 230, hoisting machine 250, and car device 240 via serial or parallel communication through a communication interface.

[0024] The following describes the renovation method for elevator 100. This renovation method involves replacing at least some of the equipment in elevator 100 with new equipment.

[0025] In this renovation project, at least the landing control panels 70 on each floor will be replaced, and at least the control devices 212 on each floor will be replaced. For convenience, in the following explanation, the same designation will be used for the landing control panels before and after replacement, the control devices before and after replacement, etc. (e.g., landing control panel 70 before replacement, landing control panel 70 after replacement).

[0026] Figure 2 is a schematic diagram showing the structure of the elevator 100. The elevator car 10 of the elevator 100 is installed in a hoistway 8 provided within the building. The car 10 moves up and down within the hoistway 8 to travel between multiple floors. In this embodiment, the car 10 can stop at each floor from the 1st floor (lowest floor) to the Nth floor (top floor).

[0027] A machine room 5 is located directly above the elevator shaft 8. The machine room 5 houses a hoisting machine 250 and a control panel 210. The elevator car device 240 is installed in the elevator car 10.

[0028] The elevator 100 in this embodiment is a rope-type elevator. This elevator 100 comprises a car 10, a counterweight 12, a rope 11, a hoisting machine 250, and a deflector wheel 13. The rope (main rope) 11 is attached to the hoisting machine 250 and the deflector wheel 13. The car 10 and the counterweight 12 are suspended from both ends of the rope 11.

[0029] The elevator 100 can move the car 10, which is installed in the hoistway 8, upward (also referred to as the "UP direction") or downward (also referred to as the "DN direction") by driving the hoisting machine 250. A buffer 14 is installed in the pit 6, which is the bottom of the hoistway 8. The buffer 14 is a device that absorbs the impact of a fall if the car 10 falls due to an abnormality.

[0030] The control device 212 is connected to the elevator car 240 via a control cable 22. The control cable 22 contains bundled signal lines for communication between the control device 212 and the elevator car 240. The control device 212 is connected to the landing devices 230, various sensors, and various switches installed on each floor via a control cable 21 that runs along the wall of the elevator shaft 8. The control cable 21 consists of multiple signal lines for communication between the control device 212 and the landing devices 230 or various switches, etc.

[0031] Figure 3 shows an example of an elevator landing for elevator 100. Figure 3 shows a front view of the elevator landing for elevator 100. In this embodiment, a landing call in the UP direction (upward) is also called an "UP call" or "UP landing call," a landing call in the DN direction (downward) is also called a "DN call" or "DN landing call," and a destination floor call inside the elevator car 10 is also called a "car call." The buttons used to register each of these calls are called "call buttons."

[0032] Call buttons include car call buttons (also called "destination floor buttons") located inside the elevator car 10 and landing call buttons (also called "landing buttons") located at the landings. Landing call buttons (landing buttons) include upward-facing landing call buttons (also called "UP call buttons" or "UP landing call buttons") located at the landings and downward-facing landing call buttons (also called "DN call buttons" or "DN landing call buttons").

[0033] As described above, each floor is equipped with a landing device 230. The landing device 230 includes a landing control panel 70. Here, we will explain using the landing on the first floor as an example. The landing on the first floor is equipped with a door 61 and a landing control panel 70. The landing control panel 70 is equipped with an UP landing call button 81 and a DN landing call button 82. For example, pressing the UP landing call button 81 registers a call for the UP landing on the first floor.

[0034] The landing control panel 70 is equipped with an indicator 71. The indicator 71 displays the direction of travel of the elevator car 10 and the floor level on which the car 10 is located (car position). In the example shown in the figure, it is indicated that the car 10 is traveling or stopped on the 2nd floor in the UP direction. In this renovation work, the replacement of equipment at the landing will include at least the replacement of the landing control panel 70, and electrical devices that transmit ON / OFF signals for the door open / closed status will also be replaced. Furthermore, the replacement work may also include mechanical devices such as the landing doors 61.

[0035] Next, the interior of the elevator car 10 will be described. Figure 4 shows an example of the interior of the elevator car 100. Figure 4 shows a view of the interior of the elevator car 10 looking towards the exit. The elevator car device 240 includes the elevator car control panel 50. The elevator car 10 is equipped with a door 60 and the elevator car control panel 50. The elevator car control panel 50 is equipped with a door open button 52 for opening the door, a door close button 53 for closing the door, and an elevator car call button 31 for registering destination floors (elevator calls) from the 1st floor to the Nth floor.

[0036] The elevator car call buttons 31 include a 1st floor call button for registering a call to the 1st floor, a 2nd floor call button for registering a call to the 2nd floor, ..., and an Nth floor call button for registering a call to the Nth floor. The elevator car control panel 50 is also equipped with an indicator 51 that displays the direction of travel and the position of the elevator car 10.

[0037] In this renovation work, the replacement work of equipment other than the landings may include the replacement of electrical equipment such as the control device 212 and the car control panel 50, and may also include the replacement of the car 10, etc.

[0038] When a landing call button is pressed, a call signal corresponding to the pressed landing call is transmitted to the control panel 210 (control device 212). The control panel 210 registers the landing call. The control panel 210 then assigns the elevator car 10 to the registered landing call and causes the elevator car 10 to respond to the registered landing call. When a car call button is pressed, a call signal corresponding to the pressed car call is transmitted to the control panel 210. The control panel 210 registers the car call. The control panel 210 causes the elevator car 10 to respond to the registered car call.

[0039] The following describes the schedule and each stage of the renovation work. Figure 5 is a diagram illustrating an example of the renovation work schedule 301. Figure 6 is a diagram showing each stage of the renovation work.

[0040] The multiple floors (1st to 16th floors) on which the landing control panel 70 is installed include a first floor group and a second floor group. In this embodiment, the first floor group is either an odd-numbered floor or an even-numbered floor. The following describes the case where the first floor group is an odd-numbered floor and the second floor group is an even-numbered floor. The first floor group includes the main floor (1st floor), which is the entrance floor. However, if the main floor is the 2nd floor, the first floor group may be an even-numbered floor and the second floor group may be an odd-numbered floor.

[0041] The method for renovating elevator 100 includes: Step 1, replacing the control device 212, etc.; Step 2, replacing the landing control panels 70 installed on each floor of the first floor group (odd-numbered floors: 1st, 3rd, 5th, 7th, 9th, 11th, 13th, 15th floors) among the multiple landing control panels 70; Step A, operating the elevator 100 by communicating the replaced control device 212 with the landing control panels 70 installed on each floor of the first floor group after the replacement; and Step 3, after Step A, replacing the landing control panels 70 installed on each floor of the second floor group (even-numbered floors: 2nd, 4th, 6th, 8th, 10th, 12th, 14th, 16th floors) among the multiple landing control panels 70. A detailed explanation follows below.

[0042] As shown in Figure 5, the renovation work schedule 301 consists of steps 1 to 3. The renovation work will be completed in A+2 days. Step 1 is the process of replacing equipment other than the landings, and steps 2 and 3 are the processes of replacing equipment on the landings.

[0043] Process 1 will be carried out over A days (one day or more) from Day 1 to Day A. The work in Process 1 involves replacing equipment other than the landing area. The equipment other than the landing area is as shown in Figure 1, but not all of it will be replaced; some or all of it will be replaced as needed. For example, some of the equipment, including the control device 212, will be replaced.

[0044] Process 2 will be carried out on day A+1. The work for Process 2 involves replacing the equipment on the landings of the odd-numbered floors (1st, 3rd, 5th...N-1st floor), which constitute the first floor group. In this case, the landing equipment 230 on the 1st, 3rd, 5th...N-1st floors shown in Figure 1 will be replaced. However, not all of the landing equipment 230 will be replaced; some or all of it will be replaced as needed. For example, some or all of the landing equipment, including the landing control panel 70 shown in Figure 3, will be replaced.

[0045] Step 3 will be carried out on day A+2. The work for Step 3 involves replacing the equipment on the landings of the even-numbered floors (2nd, 4th, 6th...Nth floors), which constitute the second floor group. In this case, the landing equipment 230 on the 2nd, 4th, 6th...Nth floors shown in Figure 1 will be replaced. Similar to Step 2, some or all of the landing equipment, including the landing control panel 70, will be replaced.

[0046] As shown in Figure 6, the renovation work is carried out by sequentially executing each step from step S101 to step S105. First, in step S101 of the renovation work, the schedule 301 of the renovation work is set. As described above using Figure 5, step 1, which involves replacing equipment other than the landings, and steps 2 and 3, which involve replacing equipment on the landings, are set as schedule 301. Subsequently, the replacement work is carried out according to the set schedule 301.

[0047] In step S102 of the renovation work, process 1 is carried out, which involves replacing equipment other than the landing area as specified in schedule 301. In this renovation work, equipment including the control device 212 will be replaced.

[0048] On the other hand, at this point, the landing control panels 70 on each floor have not been replaced. In this renovation work, the original elevator 100 and the elevator 100 after the renovation work will be manufactured by different companies, or even if the manufacturers of elevator 100 are the same, the models of elevator 100 will be different.

[0049] Therefore, the replacement control device 212 cannot communicate data with the landing control panel 70 before the replacement. In other words, at this point, the landing control panel 70 is not functioning (it is not possible to call the elevator car 10), and therefore, building users cannot use the elevator 100.

[0050] In step S103 of the renovation work, process 2 is carried out, which involves replacing the landing equipment as specified in schedule 301. Process 2 replaces the landing equipment, including the landing control panels 70, on odd-numbered floors (1st, 3rd, 5th...N-1st floor). The replaced landing control panels 70 are capable of data communication with the replaced control device 212.

[0051] After the completion of process 2 on day A+1, step S104 of the renovation work involves nighttime elevator operation (operation process A). The construction personnel turn on the power to elevator 100 and start operating elevator 100. Note that operation of the elevator is not limited to nighttime, and it is sufficient to operate the elevator between process 2 and process 3.

[0052] Since UP / DN calls can be registered on the landing control panel 70 at odd-numbered floors, users can call car 10 from odd-numbered floors and board car 10. After boarding, it is possible to register the destination floor (car call) from inside car 10.

[0053] Furthermore, if the landing control panel 70 on an odd-numbered floor is replaced, the construction worker will configure the replacement control device 212 to provide service only to odd-numbered floors (disabling service to even-numbered floors) (or to disable landing calls on even-numbered floors). As a result, elevator car 10 will respond to landing calls on odd-numbered floors. Users on even-numbered floors can use the stairs to go to an odd-numbered floor and call elevator car 10 from there.

[0054] In step S105 of the renovation work, process 3 of schedule 301 is carried out, which involves replacing the equipment at the elevator landings. This allows UP / DN calls to be registered on the landing control panels 70 at all landings. The construction personnel turn on the power to the elevator 100 and start it up. At that time, they change the settings so that all floors are serviceable. This completes the renovation work.

[0055] As described above, in this embodiment, the method for renewing the elevator 100 is a method of renewing the elevator 100 by replacing at least some of its equipment with new equipment. The equipment of the elevator 100 includes a plurality of landing control panels 70 (landing equipment) and a control device 212. The plurality of landing control panels 70 are installed on each of the plurality of floors on which the elevator car 10 of the elevator 100 can stop, and are control panels for registering landing calls to call the car 10. The control device 212 is able to communicate with the plurality of landing control panels 70 and controls the car 10 to respond to landing calls. The replaced control device 212 cannot communicate with the original landing control panel 70 among the plurality of landing control panels 70. The plurality of floors includes a first floor group (odd-numbered floors) and a second floor group (even-numbered floors). The method for renovating the elevator 100 includes the steps of replacing the control device 212 (step 1), replacing the landing control panels 70 installed on each floor of the first floor group among the multiple landing control panels 70 (step 2), operating the elevator 100 by communicating the replaced control device 212 with the landing control panels 70 installed on each floor of the first floor group after replacement (operation step A), and, after operating the elevator 100, replacing the landing control panels 70 installed on each floor of the second floor group among the multiple landing control panels 70 (step 3).

[0056] If a building has many floors, the number of landing control panels 70 that need to be replaced increases. This necessitates replacing the landing control panels 70 on each floor over several days. In this case, since the replacement control device 212 cannot communicate with the original landing control panels 70, the elevator car 10 cannot be called from any floor where the landing control panels 70 have not been replaced. By enabling communication between the replacement control device 212 and the landing control panels 70 installed on each floor of the first floor group after replacement, the elevator 100 can be operated, allowing the elevator to be used even before the completion of the renovation work. This allows the elevator to be used as much as possible even during renovation work.

[0057] The first floor group consists of odd-numbered or even-numbered floors. This allows passengers to register a landing call and board elevator car 10 from either an odd-numbered or even-numbered floor during operation phase A. For example, if boarding is possible from an odd-numbered floor during operation phase A, even if there are passengers on an even-numbered floor, they can still use the elevator by going up or down the stairs on the first floor. Similarly, if boarding is possible from an even-numbered floor during operation phase A, even if there are passengers on an odd-numbered floor, they can still use the elevator by going up or down the stairs on the first floor. This reduces the burden of movement for passengers during operation phase A.

[0058] [Differentiation] In this embodiment, during the equipment replacement work at the landings, the equipment at the odd-numbered floors is replaced as the first floor group, and then the equipment at the even-numbered floors is replaced as the second floor group. In contrast, in a modified version of this embodiment, a priority order is set for each of the multiple floors (1st to Nth floors: N=15) where the landing equipment, including the landing control panel 70, is installed, and the equipment replacement work at the landings is performed in order of priority.

[0059] Specifically, the method for renovating the elevator 100 according to the modified example includes: step 1 of replacing the control device 212, etc.; step 2 of replacing the landing control panels 70 installed on each floor of the first floor group (first priority floor) among the multiple landing control panels 70; operation step A of operating the elevator 100 by communicating the replaced control device 212 with the landing control panels 70 installed on each floor of the first floor group after replacement; and step 3 of replacing the landing control panels 70 installed on each floor of the second floor group (second priority floor) among the multiple landing control panels 70 after operation step A.

[0060] Furthermore, the renewal construction method includes, after step 3, an operation step B in which the elevator 100 is operated by communicating the replaced control device 212 with the landing control panels 70 installed on each floor of the replaced first priority floor and second priority floor, and after operation step B, a step 4 in which the landing control panels 70 installed on each floor of the third floor group (third priority floor) among the multiple landing control panels 70 are replaced.

[0061] Figure 7 is a diagram illustrating an example of schedule 302 for renovation work related to a modified example. In schedule 302, for example, the first floor group (first priority floors) is set to "1, 5...N floors", the second floor group (second priority floors) is set to "2, 6... floors", and the third floor group (third priority floors) is set to "3, 4... floors". The priority of the work increases in the order of first priority floors, second priority floors, and third priority floors, and the work is carried out in this order.

[0062] Schedule 302 for the renovation work outlines the schedule for carrying out steps 1 through 4. The renovation work will be completed in A+3 days. Step 1 involves replacing equipment other than the landing area, while steps 2 through 4 involve replacing equipment within the landing area.

[0063] Process 1 will be carried out over A days, from Day 1 to Day A. The work involved in Process 1 is the replacement of equipment other than the landing area. This is the same as Process 1 in Schedule 301 in Figure 5.

[0064] Process 2 will be carried out on day A+1. The work for Process 2 involves replacing equipment at the landings on the first priority floors (1st, 5th...Nth floors). Similar to Process 2 of Schedule 301, some or all of the equipment at the landings, including the landing control panel 70, will be replaced.

[0065] Process 3 will be carried out on day A+2. The work for Process 3 involves replacing the equipment at the landings on the second priority floors (2nd, 6th, etc.). Process 4 will be carried out on day A+3. The work for Process 4 involves replacing the equipment at the landings on the third priority floors (3rd, 4th, etc.). Processes 3 and 4, like Process 2, involve replacing some or all of the equipment at the landings, including the landing control panel 70.

[0066] Figure 8 shows the priority rule table 303 for a modified example. Here, the first to third priority levels are determined based on the priority rule table 303. The priority rule table 303 specifies three rules, rules A to C.

[0067] When carrying out construction work, one of rules A to C is selected based on the priority rule table 303, and the first to third floor groups (first priority floor to third priority floor) specified in the selected rule are used. For a 15-story building, the first to third priority floors should be allocated in groups of five floors each.

[0068] The priority assigned to floors belonging to the second floor group (second priority floor) is higher than the priority assigned to floors belonging to the third floor group (third priority floor). Also, the priority assigned to floors belonging to the first floor group (first priority floor) is higher than the priority assigned to floors belonging to the second floor group (second priority floor).

[0069] Rule A is a VIP priority rule. Under Rule A, the priority of each of the multiple floors (floors 1 to N) is higher if it is a floor designated as a VIP floor where an important person will have access to an area. Rule A prioritizes floors where VIPs reside or use (VIP floors), such as the owner's floor in an apartment building or the CEO's office in an office building.

[0070] The highest priority floor, designated as the 1st priority floor, includes the VIP floor and the main floor. There may be multiple VIP floors; in this case, they should be assigned to the 1st priority floor, 2nd priority floor, and 3rd priority floor in order of priority, from highest to lowest.

[0071] For floors other than the VIP floor and the main floor, the allocation should be done appropriately so that the distance between stopping floors is not too far. For example, if the main floor is the 1st floor (priority = 1st) and the VIP floor is the 16th floor (priority = 2nd), setting the other 1st priority floors to the 5th, 9th, and 13th floors will result in a maximum of 4 floors between stopping floors. Alternatively, setting the 2nd priority floors to the 3rd, 4th, 7th, 10th, and 11th floors (priority floor group A1) will result in a maximum of 2 floors between stopping floors. The remaining floors can then be set to 3rd priority floors (priority floor group A2).

[0072] Rule B is a priority rule for vulnerable people. Under Rule B, the priority of each floor (floors 1 to N) is higher if it is a floor where an area for vulnerable people (for example, physically vulnerable people) is provided (a floor designated as a priority floor for vulnerable people). Rule B, for example, in an apartment building, prioritizes floors where many elderly people or people with disabilities live (a floor designated as a priority floor for vulnerable people).

[0073] The highest priority floor, designated as the 1st priority floor, includes the floors designated for vulnerable passengers and the main floor. If there are many floors designated for vulnerable passengers, they should be allocated to the 1st priority floor, 2nd priority floor, and 3rd priority floor in order of priority, starting with the highest priority floor. For floors other than the floors designated for vulnerable passengers and the main floor, they should be allocated appropriately so that the distance between floors where trains can stop is not too far.

[0074] For example, if the main floor is the 1st floor (priority = 1st), and the floors with priority for vulnerable passengers are the 5th and 9th floors (priority = 2nd and 3rd), then setting the other 1st priority floors to the 13th and 16th floors would result in a maximum of 4 floors between stopping floors. Alternatively, setting the 2nd priority floors to the 3rd, 4th, 7th, 10th, and 11th floors (priority floor group B1) would result in a maximum of 2 floors between stopping floors. The remaining floors can then be set as the 3rd priority floors (priority floor group B2). It is also possible to create a rule that applies the contents of rules A and B simultaneously. In this case, the VIP floor, the floors with priority for vulnerable passengers, and the main floor should be set as the 1st priority floors (1st floor group).

[0075] Rule C is a traffic flow priority rule. In Rule C, the frequency of use (traffic flow) of car 10 on floors belonging to the second floor group is higher than the frequency of use (traffic flow) of car 10 on floors belonging to the third floor group. The frequency of use (traffic flow) of car 10 on floors belonging to the first floor group is higher than the frequency of use (traffic flow) of car 10 on floors belonging to the second floor group.

[0076] Rule C prioritizes floors based on pre-measured traffic flow (pedestrian flow) or predicted traffic flow within the building, in descending order of traffic flow. The first priority floor is the floor with the highest traffic flow, the second priority floor is the floor with the highest traffic flow, and the third priority floor is the floor with the lowest traffic flow. The magnitude of traffic flow follows the relationship: floors with high traffic flow > floors with medium traffic flow > floors with low traffic flow.

[0077] For example, the traffic flow on floor X can be calculated as: the average number of passengers boarding on floor X per day + the average number of passengers alighting on floor X per day. Then, floors can be classified in order of traffic flow, from highest to lowest: floors with high traffic flow, floors with medium traffic flow, and floors with low traffic flow. It is assumed that the main floor, which is the entrance floor, will be included in the floors with high traffic flow (first priority floor).

[0078] The frequency of use (traffic flow) of elevator car 10 is calculated based on values ​​measured by measuring devices (such as scales) that detect passenger flow inside elevator car 10 or at the landings on each floor. The calculation of traffic flow can be carried out using known methods. For example, three calculation methods, Method 1 to Method 3, are possible. Method 1 is a method of calculating traffic flow based on the number of times elevator car 10 arrives and departs (measurement of the number of times doors are opened and closed from a relay switch). Method 2 is a method of calculating traffic flow based on logistics (measurement of elevator load using a scale). Method 3 is a method of calculating traffic flow based on passenger flow (measurement of the number of passengers using a camera).

[0079] Method 1 measures the number of door openings and closings per day by directly acquiring signal information from relay switches that turn ON / OFF according to the open / closed state of the landing doors on each floor and counting these signals. In this case, it can be estimated that floors with a high number of door openings and closings per day = floors with a high number of car departures and arrivals per day = floors with high traffic flow. If communication with the control device 212 of the elevator 100 is possible, Method 2 can be used to calculate time-series information on boarding and alighting weights at each floor based on time-series information of the car load (= car weight measured by a scale installed in the car / maximum load capacity of the car) and the floor position of the car 10 held by the control device 212. Since this weight includes not only the weight of passengers but also the weight of the luggage being transported, Method 2 can measure traffic flow with a focus on "logistics". In Method 3, traffic flow is calculated based on the number of passengers that increased or decreased in the car before and after door openings and closings at each floor, based on images taken by cameras installed in the landing or inside the car. The number of people in the camera's captured image can be detected using a known method. Method 2 allows for the measurement of traffic flow focusing on "people flow".

[0080] Figure 9 is a diagram showing the steps of the renovation work related to the modified example. The renovation work related to the modified example is carried out by sequentially executing each step from step S201 to step S207.

[0081] First, in step S201 of the renovation work, a priority rule is selected from the priority rule table 303 (Figure 8) to set the renovation work schedule 302 (Figure 7). For example, if rule A of the priority rule table 303 is selected as the priority rule, the replacement work of landing equipment will be carried out with priority given to the main floor and VIP floor. If rule B is selected, the replacement work of landing equipment will be carried out with priority given to the main floor and floors with priority given to vulnerable persons. If rule C is selected, the replacement work of landing equipment will be carried out in order from the floor with the highest traffic flow.

[0082] In step S202 of the renovation work, process 1 is carried out, which involves replacing equipment other than the landing equipment as per schedule 302. In step S203 of the renovation work, process 2 is carried out, which involves replacing equipment at the landing (replacement work at the first priority floor) as per schedule 302. In step S204 of the renovation work, nighttime elevator operation (operation process A) is carried out. In step S205 of the renovation work, process 3 is carried out, which involves replacing equipment at the landing (replacement work at the second priority floor) as per schedule 302.

[0083] The construction flow from S201 to S205 is the same as that from S101 to S105, except that the floors where the landing equipment is replaced differ. However, while the replacement of all landing equipment is completed in S105, the replacement of landing equipment remains in S205. Therefore, in step S206 of the renewal work, nighttime elevator operation (operation process B) will be implemented again (boarding will be possible from the 1st and 2nd priority floors).

[0084] Then, on the following day, day A+3, step S207 of the renovation work will be carried out, specifically step 4 (replacement work on the third priority floor) of the elevator landing equipment replacement work as per schedule 302. With this, the renovation work will be completed, and the elevator will be accessible from all floors.

[0085] In the examples in Figures 5 and 6, the landing work is divided into two days, but it may also be divided into three or more days. For example, if the work on the 8th floor is divided into four days, the schedule should be set so that the stopping floors are not too far apart, such as Day 1: 1st and 5th floors, Day 2: 3rd and 7th floors, Day 2: 4th and 8th floors, and Day 3: 2nd and 6th floors. In addition, in the first floor group, a reference floor (main floor) may be set, and if the landing replacement work takes two days, floors may be set every two floors starting from the reference floor. If there are basement floors, for example, the first floor group will be set as follows: ...B4th basement floor, B2nd basement floor, 1st floor, 3rd floor... If the landing replacement work takes three days, floors may be set every three floors, and if the landing replacement work takes N days, floors may be set every N floors. Furthermore, in the first floor group, a standard floor (main floor) and the top floor may be set, and other floors may be set so as not to be uneven in the spacing between floors. Also, in the modified examples in Figures 7 to 9, the construction of the landing may be divided and carried out over two or four or more days. Note that there may be two main floors. For example, if there are two main floors, such as "basement 1st floor and 1st floor" or "1st floor and 2nd floor," then the two main floors are set in the first floor group.

[0086] As explained above, in this modified example, each of the multiple floors is assigned a priority. The priority assigned to the floors belonging to the first floor group is higher than the priority assigned to the floors belonging to the second floor group. By doing so, the convenience of passengers boarding from the floors with higher priority during operation process A (or operation process B) can be improved. This allows the elevator to be used as much as possible, even during renovation work.

[0087] The priority of each of the multiple floors increases if it is a floor with an area designated for important persons (VIP floor). This improves the convenience for passengers boarding from the floor with an area designated for important persons (VIP floor) during operation process A (or operation process B).

[0088] The priority of each of the multiple floors increases if it is a floor with an area designated for use by vulnerable persons (a floor with priority for vulnerable persons). In this way, the convenience of passengers boarding from a floor with an area designated for use by vulnerable persons (a floor with priority for vulnerable persons) during operation process A (or operation process B) can be improved.

[0089] The frequency of use (traffic flow) of car 10 on floors belonging to the first floor group is higher than the frequency of use (traffic flow) of car 10 on floors belonging to the second floor group. By doing this, the convenience of passengers boarding from floors with high usage frequency (high traffic flow) can be improved in operation process A (or operation process B).

[0090] The frequency of use of elevator car 10 is calculated based on values ​​measured by a pedestrian flow detection device (such as a weighing device) installed on each floor. In this way, during operation process A (or operation process B), the convenience of passengers boarding from floors with high usage frequency (high traffic flow) can be improved with greater accuracy, based on the actual flow of people within the building.
