DETAILED DESCRIPTION

[0024] Hereinafter, embodiments will be described with reference to the drawings.

[0031] The car 8 has a car frame 10 and a car chamber 11. The suspension body 7 is connected to the car frame 10. The car chamber 11 is supported by the car frame 10. A car door 12 is provided on the front surface of the car chamber 11.

[0032] The landings of the multiple layers are provided with landing doors 13. Each landing door 13 is opened and closed in conjunction with the car door 12 when the car 8 stops at a floor.

[0033] An adsorption material container 21 is attached to the lower portion of the car 8. The adsorption material container 21 is disposed below the car chamber 11. That is, the adsorption material container 21 is disposed outside the car chamber 11.

[0034] Figure 2 Yes means Figure 1 In Embodiment 1, when the counterweight 9 is located at the same height as the car 8, it faces the back of the car chamber 11. That is, the lifting area of ​​the counterweight 9 is located behind the lifting area of ​​the car 8 when viewed from the landing.

[0035] The car frame 10 has an upper beam 10a, a pair of vertical columns 10b, and a lower beam 10c. The upper beam 10a is horizontally fixed between the upper ends of the pair of vertical columns 10b. The first end of the suspension body 7 is connected to the upper beam 10a.

[0036] The lower beam 10c is horizontally fixed between a pair of vertical columns 10b below the upper beam 10a. The car room 11 is supported on the lower beam 10c below the upper beam 10a. The car room 11 is located between the pair of vertical columns 10b.

[0037] Although in Figure 1 Although omitted in the figure, a car sill 14 and a skirt board 15 are provided in the car room 11. The car sill 14 is provided at the lower part of the front surface of the car room 11. In addition, the car sill 14 guides the lower end of the car door 12 when the car door 12 is opened and closed.

[0038] The skirt board 15 is fixed to the car sill 14. In addition, the skirt board 15 protrudes downward from the car sill 14.

[0039] The adsorbent container 21 is supported on the lower beam 10c via a pair of support arms 16. Figure 2 In FIG. 1 , only one of the pair of support arms 16 is shown. Figure 2 A cross section of the adsorbent container 21 is shown in FIG.

[0040] The adsorption material container 21 is disposed below the lower beam 10c with a gap therebetween. Thus, a ventilation path is ensured between the lower portion of the car room 11 and the adsorption material container 21.

[0041] The adsorbent container 21 has a container body 21a and a flat container cover 21b. The container body 21a is air-permeable. When the car 8 moves downward, an upward airflow is generated in the container body 21a.

[0042] The carbon dioxide adsorbent 31 is stored in the adsorbent container 21. The carbon dioxide adsorbent 31 has air permeability. The carbon dioxide adsorbent 31 includes a plurality of granular carbon dioxide adsorbents. The outer shape of each carbon dioxide adsorbent is, for example, granular or beaded.

[0043] The structure of the carbon dioxide adsorbent 31 is not limited to a structure including a plurality of granular carbon dioxide adsorbents. For example, the carbon dioxide adsorbent 31 may be composed of a honeycomb carbon dioxide adsorbent.

[0044] The air in the hoistway 1 passes through the carbon dioxide adsorbent 31 by the movement of the car 8. That is, the air enters the adsorbent container 21 from the lower surface of the container body 21a by the downward movement of the car 8. The air entering the adsorbent container 21 passes through the carbon dioxide adsorbent 31 and is discharged to the outside of the adsorbent container 21 from the upper surface of the container body 21a.

[0045] Carbon dioxide in the air is adsorbed by the carbon dioxide adsorbent 31 when passing through the adsorbent use container 21 .

[0046] Although in Figure 1 Although omitted in the figure, an adsorbent recovery container 22 and an adsorbent replenishing container 23 are provided on the wall 1a in the hoistway 1 facing the back side of the car room 11. The adsorbent recovery container 22 and the adsorbent replenishing container 23 are arranged at intervals from each other in the vertical direction.

[0047] In addition, the adsorbent use container 21, the adsorbent recovery container 22, and the adsorbent replenishment container 23 are arranged at the same position in the width direction of the car 8. The width direction of the car 8 is a direction parallel to the opening and closing direction of the car door 12. Figure 2 The direction perpendicular to the paper.

[0048] The adsorbent recovery container 22 has a cylindrical recovery container body 22a and a flat recovery container cover 22b. The recovery container body 22a has an upper recovery container opening at its upper end and a lower recovery container opening at its lower end.

[0049] The collection container cover 22b is provided at the lower part of the collection container body 22a. In addition, the collection container cover 22b opens and closes the lower opening of the collection container.

[0050] The adsorbent replenishing container 23 has a cylindrical replenishing container body 23a and a flat replenishing container cover 23b. The replenishing container body 23a has an upper replenishing container opening at the upper end thereof and a lower replenishing container opening at the lower end thereof.

[0051] The replenishing container cover 23b is provided at the lower part of the replenishing container body 23a. In addition, the replenishing container cover 23b opens and closes the lower opening of the replenishing container.

[0052] A container opening is provided at one end of the adsorbent use container 21 that is opposite to the wall 1a provided with the adsorbent recovery container 22 and the adsorbent replenishing container 23. The container opening is opened and closed by a container cover 21b.

[0053] A replacement mechanism 24 is provided in at least one of the adsorption body container 21, the car 8, and the hoistway 1. The replacement mechanism 24 of the first embodiment includes a container rotating device 25 and a cover rotating device 26. As the container rotating device 25 and the cover rotating device 26, motors are used respectively.

[0054] The container rotating device 25 is provided on one of the support arms 16 of a pair of support arms 16. That is, the container rotating device 25 is provided on the car 8 via the support arm 16. In addition, the container rotating device 25 rotates the adsorbent using container 21 relative to the car 8 between a horizontal state and an inclined state, with the axis parallel to the width direction of the car 8 as the center.

[0055] like Figure 2 As shown, the horizontal state is a state in which the adsorbent container 21 is horizontal. Figure 3 and Figure 4 As shown, the inclined state is a state in which the adsorber container 21 is inclined relative to the horizontal plane.

[0056] The cap rotating device 26 opens and closes the container opening by rotating the container cap 21 b relative to the container body 21 a .

[0057] When the car 8 stops at a position corresponding to the adsorbent recovery container 22 , the replacement mechanism 24 connects the adsorbent use container 21 to the adsorbent recovery container 22 to move the carbon dioxide adsorbent 31 in the adsorbent use container 21 to the adsorbent recovery container 22 .

[0058] When the car 8 stops at a position corresponding to the adsorber replenishing container 23 , the replacement mechanism 24 connects the adsorber usage container 21 to the adsorber replenishing container 23 to move the carbon dioxide adsorber 31 in the adsorber replenishing container 23 into the adsorber usage container 21 .

[0059] The carbon dioxide recovery device 30 of Embodiment 1 includes an adsorbent use container 21, an adsorbent recovery container 22, an adsorbent replenishment container 23, and a replacement mechanism 24. In addition, the carbon dioxide recovery device 30 is controlled by the elevator control device 5. That is, the container rotating device 25 and the cover rotating device 26 are controlled by the elevator control device 5.

[0060] Figure 3 This means that the carbon dioxide adsorbent 31 is Figure 2 A side view of the state after the adsorbent use container 21 is moved to the adsorbent recovery container 22. Figure 3 , a cross section of the adsorbent use container 21 and the adsorbent recovery container 22 is shown.

[0061] When the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide is recovered to the adsorbent recovery container 22, the car 8 is stopped at a position corresponding to the adsorbent recovery container 22. In this example, the position corresponding to the adsorbent recovery container 22 is a position where the adsorbent use container 21 is located above the adsorbent recovery container 22 and the adsorbent use container 21 and the adsorbent recovery container 22 can be connected.

[0062] Then, the adsorbent container 21 is tilted so that the container opening faces downward. Then, the container cover 21b is rotated so that the front end of the container cover 21b contacts the edge of the upper opening of the recovery container.

[0063] As a result, the carbon dioxide adsorbent 31 in the adsorbent use container 21 moves into the adsorbent recovery container 22 due to its own weight. That is, the replacement mechanism 24 tilts the adsorbent use container 21 relative to the horizontal plane, thereby moving the carbon dioxide adsorbent 31 in the adsorbent use container 21 into the adsorbent recovery container 22 by utilizing its own weight.

[0064] Figure 4 This means that the carbon dioxide adsorbent 31 is Figure 2 A side view of the state after the adsorbent replenishing container 23 is moved to the adsorbent using container 21. Figure 4 2 shows a cross section of the adsorber use container 21 and the adsorber replenishment container 23 .

[0065] When the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished to the empty adsorbent use container 21, the car 8 is stopped at a position corresponding to the adsorbent replenishing container 23. In this example, the position corresponding to the adsorbent replenishing container 23 is a position where the adsorbent use container 21 is located below the adsorbent replenishing container 23 and is a position where the adsorbent use container 21 and the adsorbent replenishing container 23 can be connected.

[0066] After that, the adsorbent container 21 is tilted so that the container opening faces upward. Then, the container cover 21b is rotated to open the container opening. At this time, the container cover 21b hits the replenishment container cover 23b, and the replenishment container cover 23b is also rotated in the opening direction by the rotation of the container cover 21b.

[0067] As a result, the carbon dioxide adsorbent 31 in the adsorbent replenishing container 23 moves into the adsorbent using container 21 due to its own weight. That is, the replacement mechanism 24 tilts the adsorbent using container 21 relative to the horizontal plane and opens the replenishing container cover 23b, thereby moving the carbon dioxide adsorbent 31 in the adsorbent replenishing container 23 into the adsorbent using container 21 by utilizing its own weight.

[0068] When the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished into the adsorbent container 21, the container opening is closed by the container cover 21b, and the adsorbent container 21 returns to the horizontal state.

[0069] Figure 5 This is a block diagram showing the carbon dioxide recovery system of the elevator according to Embodiment 1. The carbon dioxide recovery system includes an elevator control device 5 , a carbon dioxide recovery device 30 , and a monitoring device 40 .

[0070] The monitoring device 40 includes a replacement determination unit 41 , a replacement instruction unit 42 , and a notification unit 43 as functional blocks.

[0071] The replacement determination unit 41 determines whether it is necessary to replace the carbon dioxide adsorbent 31. For example, the replacement determination unit 41 determines that it is necessary to replace the carbon dioxide adsorbent 31 based on a preset replacement cycle.

[0072] In addition, the replacement determination unit 41 may determine whether replacement is necessary based on the operation information of the car 8. In this case, the replacement determination unit 41 obtains the operation information of the car 8 from the elevator control device 5. As the operation information of the car 8, for example, there can be cited movement time information or movement distance information. The movement time information is information on the total movement time of the car 8. The movement distance information is information on the total movement distance of the car 8.

[0073] A travel time threshold or a travel distance threshold is set in the monitoring device 40. When the total travel time of the car 8 reaches the travel time threshold or the total travel distance of the car 8 reaches the travel distance threshold, the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

[0074] In addition, the weight of the carbon dioxide adsorbent 31 increases as it adsorbs carbon dioxide and moisture in the air. In addition, as carbon dioxide and moisture are adsorbed, the carbon dioxide adsorption capacity of the carbon dioxide adsorbent 31 gradually decreases. Therefore, the replacement determination unit 41 may also determine whether replacement is required based on the weight of the carbon dioxide adsorbent 31 in the adsorbent container 21.

[0075] In this case, a weight detector (not shown) is provided in the adsorbent container 21. The weight detector detects the weight of the carbon dioxide adsorbent 31. The monitoring device 40 acquires information from the weight detector directly or via the elevator control device 5.

[0076] A weight threshold is set in the monitoring device 40. Then, when the weight of the carbon dioxide adsorbent 31 reaches the weight threshold, the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

[0077] Furthermore, the replacement determination unit 41 may determine whether the carbon dioxide adsorbent 31 needs to be replaced based on the time that has passed since the carbon dioxide adsorbent 31 was last replaced.

[0078] In this case, an elapsed time threshold is set in the monitoring device 40. Then, when the elapsed time from the last replacement reaches the elapsed time threshold, the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

[0079] Furthermore, the replacement determination unit 41 may determine whether the carbon dioxide adsorbent 31 needs to be replaced based on the carbon dioxide concentration in the air that has passed through the adsorbent container 21 .

[0080] In this case, a concentration sensor (not shown) is provided in the adsorbent container 21. The concentration sensor detects the concentration of carbon dioxide.

[0081] A concentration threshold is set in the monitoring device 40. Then, when the carbon dioxide concentration in the air passing through the adsorbent container 21 becomes equal to or higher than the concentration threshold, the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced.

[0082] When the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced, the replacement instruction unit 42 transmits a replacement instruction signal to the elevator control device 5 .

[0083] When receiving the replacement instruction signal from the monitoring device 40, the elevator control device 5 moves the carbon dioxide adsorbent 31 in the adsorbent use container 21 to the adsorbent recovery container 22 at a timing when no call registration occurs. Then, the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 is moved to the adsorbent use container 21.

[0084] When the replacement instruction signal is transmitted from the replacement instruction unit 42 to the elevator control device 5, the notification unit 43 transmits a notification signal to the information center 60 via the communication network 50. The notification signal is a signal notifying that the carbon dioxide adsorbent 31 has been replaced.

[0085] When receiving the notification signal, the information center 60 notifies the person in charge of maintenance of the elevator in which the carbon dioxide adsorbent 31 has been replaced that the carbon dioxide adsorbent 31 has been replaced.

[0086] After that, the maintenance person in charge who receives the communication from the information center 60 collects the carbon dioxide adsorbent 31 from the adsorbent collection container 22 and replenishes the carbon dioxide adsorbent 31 to the adsorbent replenishment container 23. These operations can be performed by the maintenance person in charge riding on the car 8, for example.

[0087] The carbon dioxide adsorbent 31 that has adsorbed carbon dioxide is heated by a heating device (not shown). As a result, carbon dioxide is separated from the carbon dioxide adsorbent 31, and the carbon dioxide adsorbent 31 returns to the state before the carbon dioxide adsorption.

[0088] Figure 6 It means by Figure 5 The monitoring device 40 repeatedly executes the replacement determination process at a set period. Figure 6 The replacement determination process shown.

[0089] When the replacement determination process starts, the monitoring device 40 determines in step S101 whether it is necessary to replace the carbon dioxide adsorbent 31. If it is not necessary to replace the carbon dioxide adsorbent 31, the monitoring device 40 ends this process.

[0090] When the carbon dioxide adsorbent 31 needs to be replaced, the monitoring device 40 transmits a replacement instruction signal to the elevator control device 5 in step S102. Thereafter, the monitoring device 40 transmits a notification signal to the information center 60 in step S103, and the processing ends.

[0091] In such an elevator and its carbon dioxide recovery device 30, the adsorbent container 21 is provided in the car 8. The carbon dioxide adsorbent 31 is stored in the adsorbent container 21. By moving the car 8 in a state where the carbon dioxide adsorbent 31 is stored in the adsorbent container 21, the air in the hoistway 1 passes through the carbon dioxide adsorbent 31, and the carbon dioxide in the air is adsorbed by the carbon dioxide adsorbent 31.

[0092] Therefore, regardless of the vertical length of the hoistway 1, the carbon dioxide in the hoistway 1 can be efficiently recovered by the driving force of the hoisting machine 3.

[0093] In addition, an adsorbent recovery container 22 is provided in the shaft 1 . Then, the replacement mechanism 24 connects the adsorbent use container 21 and the adsorbent recovery container 22 to move the carbon dioxide adsorbent 31 in the adsorbent use container 21 to the adsorbent recovery container 22 .

[0094] Therefore, regardless of the position of the adsorbent container 21 in the car 8, the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide can be easily recovered, and the labor of maintenance work can be reduced.

[0095] In addition, the replacement mechanism 24 tilts the adsorbent use container 21 relative to the horizontal plane, thereby using the weight of the carbon dioxide adsorbent 31 to move the carbon dioxide adsorbent 31 in the adsorbent use container 21 to the adsorbent recovery container 22. Therefore, the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide can be easily recovered with a simple structure.

[0096] In addition, an adsorbent replenishing container 23 is provided in the shaft 1. Then, the replacement mechanism 24 connects the adsorbent use container 21 to the adsorbent replenishing container 23 to move the carbon dioxide adsorbent 31 in the adsorbent replenishing container 23 to the adsorbent use container 21.

[0097] Therefore, the carbon dioxide adsorbent 31 before carbon dioxide adsorption can be easily replenished regardless of the position of the adsorbent container 21 in the car 8, which can reduce the labor of maintenance work.

[0098] In addition, the carbon dioxide recovery efficiency can be maintained for a longer period of time, and the interval between maintenance operations can be extended.

[0099] In addition, the replacement mechanism 24 tilts the adsorbent use container 21 relative to the horizontal plane and opens the replenishment container lid 23b, thereby moving the carbon dioxide adsorbent 31 in the adsorbent replenishment container 23 into the adsorbent use container 21 by utilizing the self-weight of the carbon dioxide adsorbent 31. Therefore, the carbon dioxide adsorbent 31 before carbon dioxide adsorption can be easily replenished with a simple structure.

[0100] In the monitoring device 40 of the carbon dioxide recovery system of Embodiment 1, the replacement determination unit 41 determines whether the carbon dioxide adsorbent 31 needs to be replaced. Then, when the replacement determination unit 41 determines that the carbon dioxide adsorbent 31 needs to be replaced, a replacement instruction signal is sent to the elevator control device 5.

[0101] Therefore, by replacing the carbon dioxide adsorbent 31 at a more appropriate timing, the adsorption performance of the carbon dioxide adsorbent 31 is maintained, and carbon dioxide can be efficiently recovered for a longer period of time.

[0102] Furthermore, when a replacement instruction signal is transmitted from the replacement instruction unit 42 to the elevator control device 5, a notification signal is transmitted from the notification unit 43 to the information center 60. Therefore, the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide can be recovered at a more appropriate timing, or the carbon dioxide adsorbent 31 before carbon dioxide adsorption can be replenished. As a result, carbon dioxide can be efficiently recovered for a longer period of time, and the labor of maintenance work can be reduced.

[0103] In addition, the adsorber recovery container 22 and the adsorber replenishing container 23 may be arranged on a wall of the hoistway 1 that is opposite to the side surface of the car chamber 11 , avoiding the car guide rails.

[0104] Implementation method 2.

[0105] then, Figure 7 1 is a side view showing the main parts of the elevator of Embodiment 2. Figure 1 Although omitted in the figure, a landing sill 17 is provided at each of the multiple landings. Each landing sill 17 guides the lower end of the landing door 13 when the landing door 13 is opened and closed. A protective plate 18 is provided at the lower part of each landing sill 17.

[0106] The adsorbent recovery container 22 and the adsorbent replenishing container 23 are arranged on different protective plates 18. In addition, the adsorbent recovery container 22 and the adsorbent replenishing container 23 each serve as a part or the whole of the protective plate 18. In addition, the adsorbent recovery container 22 and the adsorbent replenishing container 23 can also be containers installed on the flat protective plate 18.

[0107] The adsorber recovery container 22 and the adsorber replenishing container 23 are respectively located in the range between the wall 1b on the landing side of the hoistway 1 and the end surface of the landing sill 17 on the hoistway 1 side in the front-to-back direction of the car 8. The front-to-back direction of the car 8 is a direction perpendicular to the width direction of the car 8 and horizontal.

[0108] A collection container door 27 is provided on the landing wall of the floor where the adsorbent collection container 22 is provided. The collection container door 27 opens and closes a collection container opening (not shown). The carbon dioxide adsorbent 31 in the adsorbent collection container 22 can be taken out from the landing through the collection container opening.

[0109] At this time, the carbon dioxide adsorbent 31 is taken out from the adsorbent recovery container 22 while the adsorbent recovery container 22 is set in the shaft 1. Alternatively, the carbon dioxide adsorbent 31 may be taken out from the adsorbent recovery container 22 while the adsorbent recovery container 22 is taken out to the landing.

[0110] A replenishment container door 28 is provided on the landing wall of the floor where the absorbent replenishment container 23 is provided. The replenishment container door 28 opens and closes a replenishment container opening (not shown). Carbon dioxide absorbents 31 can be replenished from the landing into the absorbent replenishment container 23 through the replenishment container opening.

[0111] At this time, the carbon dioxide adsorbents 31 are replenished in the adsorbent replenishing container 23 while the adsorbent replenishing container 23 is set in the shaft 1. Alternatively, the carbon dioxide adsorbents 31 may be replenished in the adsorbent replenishing container 23 while the adsorbent replenishing container 23 is taken out to the landing.

[0112] Thus, in Embodiment 2, the carbon dioxide adsorbent 31 can be taken out from the adsorbent recovery container 22 from the landing. In addition, the carbon dioxide adsorbent 31 can be replenished to the adsorbent replenishment container 23 from the landing.

[0113] The other structures in the second embodiment are the same as those in the first embodiment.

[0114] According to such a configuration, it is possible to obtain the same effects as those of Embodiment 1. In addition, it is possible to further reduce the time and effort required for maintenance work.

[0115] In addition, the carbon dioxide adsorbent 31 can be taken out from the adsorbent recovery container 22 and replenished into the adsorbent replenishing container 23 without stopping the operation of the car 8. Therefore, compared with the case where the replacement operation of the carbon dioxide adsorbent 31 is performed on the car 8, the degree of freedom of the timing of the replacement operation is improved. As a result, the time for the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide to enter the adsorbent recovery container 22 and the time for the adsorbent replenishing container 23 to become empty can be shortened, and the recovery efficiency of carbon dioxide in the hoistway 1 can be further improved.

[0116] In addition, the adsorbent recovery container 22 and the adsorbent replenishing container 23 are respectively provided on the protection plate 18. Therefore, the adsorbent recovery container 22 and the adsorbent replenishing container 23 can be provided in the hoistway 1 while effectively utilizing the space in the hoistway 1.

[0117] Alternatively, the method of recovering the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide may be a method of replacing the adsorbent recovery container 22 filled with the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide with an empty adsorbent recovery container 22 .

[0118] Alternatively, the carbon dioxide adsorbent 31 before carbon dioxide adsorption may be replenished by replacing an empty adsorbent replenishing container 23 with an adsorbent replenishing container 23 filled with the carbon dioxide adsorbent 31 before carbon dioxide adsorption.

[0119] In addition, the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be set as a common container. That is, a recovery and replenishment container that serves as both the adsorbent recovery container 22 and the adsorbent replenishment container 23 may be used. At this time, the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide is taken out from the recovery and replenishment container, and the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished to the recovery and replenishment container. In addition, the carbon dioxide adsorbent 31 before carbon dioxide adsorption is replenished from the recovery and replenishment container to the adsorbent use container 21, and the carbon dioxide adsorbent 31 that has adsorbed carbon dioxide is recovered from the adsorbent use container 21 to the recovery and replenishment container.

[0120] In Embodiment 1 and Embodiment 2, the adsorption body container 21 may be provided at a position other than the lower portion of the car 8 , for example, at the upper portion of the car 8 .

[0121] Furthermore, in Embodiment 1 and Embodiment 2, the replacement mechanism 24 may be provided in the car 8 or the hoistway 1 .

[0122] In addition, in Embodiment 1 and Embodiment 2, the number of adsorbent use containers 21, the number of adsorbent recovery containers 22, and the number of adsorbent replenishment containers 23 may be two or more, respectively.

[0123] In Embodiment 1 and Embodiment 2, the movable body may be the counterweight 9. That is, the adsorption body container 21 may be provided in the counterweight 9. In addition, the adsorption body container 21 may be provided in both the car 8 and the counterweight 9.

[0124] Moreover, in Embodiment 1 and Embodiment 2, the monitoring device 40 may be integrated with the elevator control device 5. Moreover, the monitoring device 40 may be installed in the information center 60.

[0125] In addition, the type of elevator is not limited to Figure 1 The type of, for example, can also be a 2: 1 roping method. In addition, the lifting area of ​​the counterweight 9 can also be located on the side of the lifting area of ​​the car 8 when viewed from the landing.

[0126] In addition, the elevator may be a machine room-less elevator, a double-deck elevator, a single-shaft multi-car elevator, etc. The single-shaft multi-car elevator is a system in which an upper car and a lower car arranged just below the upper car are independently raised and lowered in a common shaft.

[0127] In addition, each function of the elevator control device 5, the monitoring device 40, and the information center 60 in Embodiment 1 and Embodiment 2 is realized by a processing circuit. Figure 8 This is a block diagram showing a first example of a processing circuit for realizing the functions of the elevator control device 5, the monitoring device 40, and the information center 60 according to Embodiments 1 and 2.

[0128] In addition, the processing circuit 100 is equivalent to, for example, a single circuit, a composite circuit, a programmable processor, a parallel programmable processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a circuit formed by combining them. In addition, the functions of the elevator control device 5, the monitoring device 40, and the information center 60 may be realized by respective processing circuits 100, or the functions may be realized by the processing circuit 100 in a unified manner.

[0129] in addition, Fig. 9 This is a block diagram showing a second example of a processing circuit for realizing the functions of the elevator control device 5 , the monitoring device 40 , and the information center 60 in Embodiments 1 and 2. The processing circuit 200 of the second example includes a processor 201 and a memory 202 .

[0130] In the processing circuit 200, each function of the elevator control device 5, the monitoring device 40, and the information center 60 is realized by software, firmware, or a combination of software and firmware. Software and firmware are described as programs and are stored in the memory 202. The processor 201 realizes each function by reading and executing the program stored in the memory 202.

[0131] The program stored in the memory 202 can also be said to be a program that causes the computer to execute the steps or methods of the above-mentioned parts. Here, the memory 202 is, for example, a non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable and Programmable Read Only Memory). In addition, a magnetic disk, a floppy disk, an optical disk, a CD, a mini disk, a DVD, etc. also correspond to the memory 202.

[0132] Furthermore, the functions of the above-described components may be partially implemented by dedicated hardware and partially implemented by software or firmware.
