Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator system.

[Conventional technology]

BACKGROUND ART Conventionally, an elevator apparatus installed in a building or the like includes an elevator shaft provided along the vertical direction of the building, and a cage for accommodating users. The cage is suspended in the elevator shaft by a wire cable, and is raised and lowered within the elevator shaft by winding and pulling out the wire cable, and moves to the floor where the user calls and transports the user. .

However, conventional elevator systems cannot accommodate multiple cages within one elevator shaft. Therefore, in order to increase the amount of transportation per unit time of users and per unit area of the building, it is necessary to increase the moving speed of the cage or increase the number of elevator shafts. However, there is a limit to the moving speed of the cage, and if the number of elevator shafts is increased, the usable area of each floor of the building will be reduced, resulting in the problem that the space within the building cannot be used effectively. Ta.

For this reason, the present applicant constructed an elevator passageway by a plurality of elevator passageways and a traverse passageway that communicates between the elevator passageways on any floor, and moved each of the plurality of cages up and down within the elevator passageway. An elevator device has been proposed which is movable in the downward direction and between the ascending and descending passages via the traverse passage (see Japanese Patent Application No. 72852/1999). This makes it possible to accommodate a plurality of cages within the elevator shaft, increasing the amount of passengers carried per unit time.

The control device of the elevator system also communicates with each car via leaky coaxial cables disposed along the elevator path to identify the location of the source and determine the location of each car. A controller controlled the movement of each cage based on its position.

[Problem to be solved by the invention]

However, in order to determine the position of each cage by communicating and specifying the location of the transmission source, control becomes complicated, and the accuracy of detecting the location of the cages is also low. Further, errors are likely to occur due to the influence of electromagnetic waves entering the elevator passage from the outside and electromagnetic waves generated by the operation of the elevator.

The present invention was made in consideration of the above-mentioned fact, and an object of the present invention is to obtain an elevator system that can easily and accurately detect the position of each car.

[Means to solve the problem]

In the invention described in claim (1), there is provided a cage housed in an elevator passage, a moving means for moving the cage along the elevator passage, and a plurality of cages arranged along the elevator passage at the arrangement site. and a control means that determines the position of the cage based on the detection results of the plurality of detection means and controls the moving means so that the cage moves to a target position and stops. are doing.

In the invention set forth in claim (2), a plurality of cages housed in an elevator passage, a plurality of moving means for moving each of the cages along the elevator passage, and a plurality of moving means provided in each cage and different for each cage. a display section that displays information;
a plurality of detection means arranged along the elevator passageway for detecting the presence or absence of a car at the arrangement site and reading the information displayed on the display section; control means for determining the position of each cage based on the detection results of the plurality of detection means and controlling each of the plurality of moving means so that each cage moves to its respective target position and stops; have.

In the invention set forth in claim (3), a plurality of cages housed in an elevator passage, a moving means for moving each of the plurality of cages along the elevator passage, and a plurality of cages for each of the plurality of cages. a reflecting means that is provided at a different location for each area and reflects the laser; a detecting means that emits a laser toward the reflecting means and detects the laser that is reflected back from the reflecting means; Based on the laser, the part of the cage where the reflecting means is provided is determined to identify each cage, and the position of the cage is determined based on the laser, and each cage is moved to a target position and stopped. and control means for controlling the moving means.

[Effect]

In the invention described in claim (1), a plurality of detection means for detecting the presence or absence of a cage are arranged along the passage, and the position of the cage is determined based on the detection results of the plurality of detection means. As a result, the position of the cage matches the location of the detection means that detects the presence of the cage, so that the location of the cage can be detected easily and accurately.

In the invention described in claim (2), each of the plurality of cars housed in the elevator passage is provided with a display section that displays four different pieces of information for each car, and the detection means detects the presence or absence of the cage, and the display section I am trying to read the information displayed on the screen. As a result, in addition to the above effects, each car can be easily identified from the different information read for each car, and the position of each car can be easily determined even in an elevator system having multiple cars. I can do it. Note that the display section can display a different barcode for each cage, for example, and the detection section can be configured with a barcode league that reads the barcode.

In the invention described in claim (3), the reflecting means for reflecting the laser is provided at a different part for each cage, the laser reflected by the reflecting means and returned is detected, and the reflecting means is activated based on the detected laser. Each cage is identified by determining its location, and the location of the cage is determined. For example, by providing the same number of detection means as the number of cages and making each detection means correspond to the part of each cage where the reflection means is provided, it is possible to detect the laser by determining which detection means has detected the laser. It is possible to identify which cage is located, and determine the position of the cage by measuring the time from when the laser is emitted until it is reflected back. As a result, the car position detection accuracy does not depend on the number of detection means, so there is no need to provide a large number of detection means along the elevator passage, and the structure becomes simple.

FIG. 1 shows a building 10 in which the elevator system of the present invention is installed. The building 10 is provided with an elevator shaft 12 through which a car 18 (described later) of the elevator system moves. The elevator shaft 12 has a shaft 4 extending in the vertical direction of the building 10.
It is composed of a book lifting passage 14 and a traversing passage 16 that connects each lifting passage 14 at a predetermined floor of the building 100. The cage 18 is movable within the lifting passage 14 in the upward and downward directions, and is movable within the traversing passage 16 in the horizontal direction, the so-called traversing direction. Note that the elevator system of this embodiment has eight cages 18.

As shown in FIG. 2, four guide rails 20 for lifting are arranged along the passage 14 for lifting and lowering. Each lifting guide rail 20 has an H-shaped or 1-shaped cross section. Furthermore, four guide rails 22 for traversing, each having an H-shaped cross section, are arranged along the passage 16 for traversing, similar to the guide rails 20 for elevating and lowering. Further, rotating rails 21 are disposed near the upper end and the lower end of the connecting portion between the lifting passage 14 and the traversing passage 16, respectively.

The rotating rail 21 has an H-shaped cross section like the lifting guide rail 20 and the traversing guide rail 22, and the rotating shaft 24 is supported by a bearing 26 and can rotate around the rotating shaft 24. . The rotating rail 21 corresponds to the lifting guide rail 20 at the position shown in FIG. 3, and corresponds to the traversing guide rail 22 at a position rotated by 90 degrees from the position shown in FIG.
corresponds to A stopper 28 is attached to the tip of the traverse guide rail 22. The rotation of the rotating rail 21 is limited by this stopper 28 from the position corresponding to the guide rail 20 for landing shown in FIG. There is.

A rail 30 formed in an arc shape and an electromagnet 32 formed in an arc shape are arranged around the rotation shaft 24 of the rotation rail 210 (see FIG. 3).

As shown in FIG. 4, the rail 30 has a U-shaped cross section, and two pairs of rollers 34 are attached to the rotating rail 21 to sandwich the rail 30. Further, a permanent magnet 36 is attached to the rotating rail 21 and protrudes from the rotating rail 21 in correspondence with the electromagnet 32. Electromagnet 3
2 and the permanent magnet 36 constitute a rotating linear motor 38 (see FIG. 6), the operation of which is controlled by a control device 40. When a voltage is applied to the electromagnet 32, the rotary rail 21 rotates in the direction of the arrow in FIG. 3 or in the opposite direction based on the principle of a known synchronous linear motor.

Support portions 42 are attached to the ends of the upper and lower surfaces of the cage 18 that accommodates the occupant (see FIG. 2). Third
As shown in the figure, a holding part 44 is rotatably supported by each support part 42 .

The holding portion 44 rotatably supports a pair of rollers 46 arranged at a predetermined interval. This pair of rollers 46
are sandwiching the lifting guide rail 20. Thereby, the cage 18 is guided by the lifting guide rails 20 and is movable in the lifting and lowering passages 14 in the upward and downward directions. Further, when the rotating rail 21 rotates with the cage 18 stopped at the position where the pair of rollers 46 is shown in FIG. Thereby, the cage 18 is guided by the traverse guide rail 22 and can traverse within the traverse passage 16. Further, as shown in FIG. 4, the holding part 44 rotatably supports a pair of auxiliary rollers 48, and when the cage 18 moves in the upward and downward directions, and when the cage 18 moves horizontally, the holding section 44 comes into contact with each guide rail. It is designed to assist in the movement of 18.

As shown in FIGS. 2 and 5, an electromagnet 50 is installed between the two lifting guide rails 20, and a plurality of electromagnets 50 are arranged along the entire length of the lifting passage 14. ing. A lifting magnet 52 made of a permanent magnet is also attached to the cage 18 in correspondence with the electromagnet 50. The electromagnet 50 and the lifting magnet 52 are maintained at a predetermined distance by the lifting guide rail 20. As a result, the electromagnet 50 and the lifting magnet 52 are
constitutes an elevating linear motor 54 (see Fig. 6) with the elevating magnet 52 as a primary side and the elevating magnet 52 as a secondary side, and operates as a synchronous linear motor by applying voltage to the electromagnet 50. A device 40 controls its operation. By controlling the magnitude and frequency of the voltage applied to the electromagnet 50 by the control device 40, the cage 18
moves in the ascending and descending directions within the elevating passage 14, and its movement is stopped. Note that when the cage 18 is lowered (and when it stops moving), regenerative braking is performed in which the elevating linear motor 54 acts as a generator to convert the kinetic energy of the cage 18 into electric power and return it to the power supply system.

Further, as shown in FIG. 5, a plurality of electromagnets 56 are arranged along the traverse passage 16 near the traverse guide rail. A traverse magnet 58 is also attached to the cage 18 in correspondence with the electromagnet 56 (see also FIG. 2). Between the electromagnet 56 and the traverse magnet 58 is the traverse guide rail 2.
2 at a predetermined interval. As a result, the electromagnet 56 and the traverse magnet 58 are connected to the traverse linear motor 60 (
(see FIG. 6), and its operation is controlled by a control device 40. applied to the electromagnet 56 by the control device 40;
By controlling the magnitude and frequency of the voltage,
The cage 18 moves in the traversing passage 16 in the traversing direction along the traversing passage 16, and the movement in the traversing direction is stopped.

Further, a brake device W62 protruding from the cage 18 is attached to the cage 18 (see FIG. 2). The brake device 62 has the role of stopping the movement of the cage 18, and stops the cage 18 by sandwiching the lifting guide rail 20 or the traversing guide rail 22 with brake shoes (not shown).

Further, as shown in FIG. 2, a display section 82 is provided on the side surface of the cage 18. The display section 82 is constructed by pasting a sheet material or the like on which a barcode is printed at a predetermined position on the side surface of the cage 18 . The display section 82 has eight cages 18
The barcodes displayed on each cage 18 are different. The cage 18 can be identified by reading this barcode. A plurality of barcode readers 84 are arranged inside the lifting passage 14 along the lifting passage 14. When the cage 18 moves up and down, the display section 82 corresponds to each barcode reader 84 disposed along the up/down path 14 in turn. Thereby, the barcode reader 84 corresponding to the display section 82 can read the barcode displayed on the display section 82.

Further, as shown in FIG. 2, a plurality of barcode readers 84 are disposed within the traverse passage 16 along the traverse passage 16. When the cage 18 traverses within the traverse passage 16,
Similarly, the display section 82 corresponds in turn to each barcode reader 84 disposed along the traverse path I6, and the displayed barcode is read by the barcode reader 84. Each barcode reader 84 is connected to the control device 40 (see FIG. 6), and outputs information represented by the read barcode to the control device 40. When the barcode information is input from the barcode reader 84, the control device 40 determines that the barcode reader 84 has detected the presence of the cage 18. Note that each barcode reader 84 is conveniently assigned an address according to its installed position, and each barcode reader 84 outputs the address information assigned to itself along with the barcode information.

The control device 40 stores in a memory (not shown) a table showing the correspondence between the address of the barcode reader 48 and the location of the barcode reader 48 to which the address is assigned.
The position of each cage 18 can be determined based on the signal input from the barcode reader 48.

As shown in FIG. 2, a power supply line 64 is disposed near the electromagnet 50 along the lifting passage 14. cage 18
A current collecting brush 66 that contacts the power supply line 64 is attached to the power supply line 64 in correspondence with the power supply line 64 (see FIG. 5). Electric power is supplied to the cage 18 from a power supply line 64 through a current collecting brush 66, and is used to operate lighting inside the cage 18, a motor (not shown) for opening and closing the door 68, and the like. Furthermore, an information cable 70 is disposed near the electromagnet 50 along the lifting passage 14. The information cable 70 is composed of a leaky coaxial cable, and radiates a signal being transmitted to the surroundings as a leakage current, and receives a signal from the cage 18, which will be described later. An antenna 72 that receives a signal leaked from the information cable 70 and a transmitter 78 that transmits a signal toward the information cable 70 are attached to the cage 18 in correspondence with the information cable 70. This allows information to be transmitted between the inside and outside of the cage 18.

As shown in FIG. 6, the information cable 70 connects to the control device 40.
It is connected to the. Furthermore, inside the cage 18, an operation panel 74 that is operated by an occupant and a sensor 76 that detects the presence or absence of an occupant inside the cage 18 are attached.

The sensor 76 includes, for example, an infrared sensor that emits infrared rays to detect the presence or absence of an occupant. When the destination floor is specified by the passenger operating the control panel,
This destination floor is transmitted as a signal from the transmitter 78 and input to the control device 40 via the information cable 70.

Further, the output signal of the sensor 76 is also inputted to the control device 40 from the transmitting device 78 via the information cable 70 .

Further, a call button 78 for a user of the elevator device to call the car 18 is installed in the waiting space of each floor. Each call button 78 is connected to a control device. The control device 40 detects the call of the cage 18 by the user when the call button 78 is operated.

Next, the operation of the first embodiment will be explained.

First, with reference to the flowchart in FIG.
The interrupt processing will be explained. The interrupt routine shown in FIG. 7 is activated when each barcode reader 84 detects a barcode on the display section 82, and processes the detected barcode information. Also, the cage 18 stops and the display section 82
The barcode reader 84 is maintained in a state corresponding to
is executed at predetermined time intervals to process detected barcode information.

In step 200, the cage management information is referred to and the cage number is identified from the detected barcode information. The cage management information is stored in the memory of the control device 4o, for example, as a table as shown below.

Table Each cage 18 is given a cage number for convenience, and cage management information representing the state of the cage 18 corresponding to the cage number is stored in each cage 18 in the table. In the next step 202, the identified cage NO.
The stored detection time and address are read by referring to the cage management information corresponding to the cage management information. Note that the detection time and address read at this time are the detection time and the address of the barcode reader 84 when the car 18 corresponding to the cage number was detected last time.

In the next step 204, the previous address and the current address are compared to determine whether there has been a movement since the previous time. If the determination in step 204 is negative, the process moves to step 210. If the determination in step 204 is affirmative, the moving direction of the cage 18 is determined in step 206 based on the previous address and the current address.

In step 208, the moving speed of the cage 18 is calculated based on the elapsed time and moving distance since the previous detection. In step 210, cage management information is written into the table and the process ends.

Through the above processing, the cage management information is updated according to changes in the status of each cage 18, and the status of each cage 18 is grasped.

Next, control for moving each cage 18 using the cage management information will be described with reference to the flowchart shown in FIG.

In step 250, it is determined whether there is an instruction to move the cage 18. The cage 18 is instructed to move by operating the call button 78 by the user or by operating the operation panel 74 by an occupant in the cage 18 and specifying a destination floor. If there is no instruction to move the car 18, step 250 is repeated until the car 18 is called or a destination floor is designated.

If there is a movement instruction, the cage management information stored in the memory is read out in step 252, and the cage 18 to be moved is selected in step 254 in accordance with the movement instruction. In the case of a movement instruction using the call button 78, the cage 18 located near the floor where the call button 78 was operated is selected based on the read cage management information.

Further, in the case of a movement instruction using the operation panel 74, the operation panel 74 selects the operated cage 18.

In the next step 256, the destination floor of the selected cage 18 is determined and a moving route is set. In the case of a movement instruction using the call button 78, the floor on which the call button 78 was operated is determined as the destination floor, and in the case of the movement instruction using the operation panel 74, the designated destination floor is determined as the destination floor. Regarding the method of setting the movement route, for example, it is assumed that a movement route connects the current position of the selected cage 18 and the destination floor, and if another cage 18 is stopped on the movement route, a lateral movement route is set. The assumed moving route is changed to move to another lifting passage 14 via the passageway 16, and a moving route is set. In addition, when traversing, the movement route is set so that the cage 18 traverses through the traversing passage 16 where no cage 18 currently exists.

In step 258, the address of the barcode reader 84 corresponding to the stop position on the moving route and the address of the barcode reader 84 corresponding to the deceleration start position are determined. The number of stop positions and deceleration start positions changes depending on the moving route, as shown in FIG. 9, for example. For example, in Figure 9 (
As shown in A), when the movement route to the destination floor is the downward movement route 86, there is only one stop position and one deceleration start position. Further, as shown in FIG. 9(B), in the case of a moving route 88 in which the moving route moves laterally and then ascends to reach the destination floor, there are two stopping positions and two deceleration starting positions. Further, as shown in FIG. 9(C), in the case of a moving route 90 in which the moving route descends, traverses, and descends to reach the destination floor, there are three stop positions and three deceleration start positions. In step 258, the addresses of the barcode reader 84 corresponding to the stop position and deceleration start position are determined according to the movement route set in step 256.

In the following steps 260 to 274, the cage is moved to the stop position. That is, step 260
Then, it is determined whether the movement of the cage 18 to the stop position is a lateral movement. If the determination in step 260 is affirmative, in step 262 the rotation rail 21 disposed between the current position of the cage 18 and the first stop position is adjusted so that it corresponds to the traverse guide rail 22. The linear motor 38 is activated. Further, if the determination in step 260 is negative, in step 264 the rotation rail 21 arranged between the current position of the cage 18 and the above-mentioned first stop position is adjusted so as to correspond to the lifting guide rail 20. The rotation linear motor 38 is operated.

In the next step 266, the elevating linear motor 54 or the traversing linear motor 60 is activated to start moving the cage 18 to the stop position. In the next step 268, it is determined whether the cage 18 has reached the deceleration start position. This determination is made by determining whether the address stored as cage management information matches the address of the barcode reader 84 corresponding to the deceleration start position. If the determination at step 268 is negative, step 268 is repeated until the determination is affirmative. If the determination in step 268 is affirmative, in step 270, the elevating linear motor 54 or the traversing linear motor 60 is controlled so that the cage 18 is decelerated at a predetermined deceleration acceleration. As a result, the cage 18 is controlled to substantially stop at the stop position.

In step 272, it is determined whether the cage 18 has reached the stop position. This determination is made by determining whether the address stored as cage management information matches the address of the barcode reader 84 corresponding to the stop position. If the determination at step 272 is negative, step 272 is repeated until the determination is affirmative. If the determination in step 272 is affirmative, step 274 stops the movement of the cage.

In step 276, it is determined whether the cage 18 has reached the destination floor. This determination is made by determining whether the position where the car is currently stopped is the last position on the movement route. If there are a plurality of stopping positions on the movement route, for example, the above-mentioned movement route 88.
In a case like 90, this judgment is denied and step 2
Returning to step 60, the cage 18 is moved to the next stop position in steps 260 to 274. If there is only one stop position on the moving route, such as moving route 86, the determination in step 276 is affirmative and the process proceeds to step 2.
The process returns to step 50 and the above process is repeated.

Note that letters or numbers may be used instead of the barcode and read to identify each cage 18.

Furthermore, in cases where there is a one-to-one correspondence between the car and the elevator shaft as in a conventional elevator system and there is no need to identify the car, the barcode reader 84 is used to detect the presence or absence of the car. A sensor such as an infrared sensor may also be used.

Second Embodiment Next, a second embodiment of the present invention will be described. Note that the same parts as in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 10, a reflective section 100 is provided on the side surface of each cage 18 in the second embodiment in place of the display section 82 described above. Reflector 100 has a single protrusion 104. The position where the protrusion 104 is provided is in each cage 18.
They are different for each car 18, and are offset along a direction perpendicular to the up-and-down direction of the car 18. FIG. 1G shows, as an example, a protrusion 104 provided at a position corresponding to the cage 18 whose cage number is "1".

Further, a reflecting member (not shown) is attached to the lower surface of the protrusion 104 to reflect laser and the like, and constitutes a part of the reflecting means.

Also provided on the side of each cage 18 is a reflector 8102 with a single protrusion 106. The positions where the protrusions 106 are provided are offset for each cage along the direction perpendicular to the transverse direction of the cage 18. In FIG. 10, a protrusion 105 provided at a position corresponding to the cage 18 with cage number "1" is shown as an example. Also,
A reflecting member (not shown) is attached to the side surface of the protrusion 106 to reflect laser or the like, and together with the protrusion 104 constitutes a reflecting means.

As shown in FIG. 11, a laser processing device 108 is installed at the bottom of each of the four lifting passages 14. As shown in FIG. 10, each laser processing apparatus 108 includes the same number of laser processing units 110 each consisting of a pair of a laser transmitting section and a laser receiving section as the number of each cage 180. Each laser processing unit 110 corresponds to a different installation position of the protrusion 104 for each cage 18 described above, and for example, the 10th
The laser processing unit 110 disposed on the leftmost side of the figure corresponds to the installation position of the protrusion 104 whose cage number is "1". Each laser processing unit is arranged so that the locus of the laser beam transmitted by the laser transmitting section matches the locus of movement of the protrusion 104 when the corresponding cage 18 moves up and down within the elevating passage 14, and Cage 18 corresponding to inside 14
is adjusted so that the transmitted laser beam is reflected by the reflective member of the protrusion 104 and received by the laser light receiving section.

As shown in FIG. 11, absorption devices 116 are provided at the top of the lifting passage 14 in correspondence with the laser processing devices 108, respectively. The laser beam sent out from each laser processing unit 110 of the laser processing device 108 is transmitted through the lifting passage 14.
projection 10 if a corresponding cage 18 is present;
If the cage 18 is not present, the light is reflected by the absorption device 116 and is absorbed without being reflected or transmitted. Therefore, when a laser beam is transmitted from each laser processing unit 110, only the laser processing unit 110 whose corresponding cage 18 is present in the lifting passage 14 receives the laser beam.

Further, a laser processing device 112 similar to the above is attached to one end of each traverse passage 16, and an absorption device 118 is attached to the other end.
is installed. If a corresponding cage 18 exists in the traverse passage 16, the laser emitted from each laser processing unit 114 (see FIG. 10) of the laser processing apparatus 112 is reflected by the protrusion 106 and passes through the laser receiving section. If the cage 18 is not present, the light enters the absorption device 118 and is absorbed without being reflected or transmitted. Therefore, similarly to the above, each laser processing unit 11
4, the laser processing unit 114 has a corresponding cage 18 in the traverse passage 16.
only the target receives the laser beam.

As shown in FIG. 12, each laser processing device 108.11
2 is connected to the control device 40. Laser processing device 1
08.112 transmits laser light in a pulsed manner from the laser transmitting section of each laser processing unit 110.114, and when the transmitted laser is reflected by the protrusion 104 or the protrusion 106 and received by the laser receiving section, Information indicating which cage 18 the laser processing unit 110, 114 that has received the laser beam corresponds to is output to the control device t40.

In addition, the distance to the protrusion 104 or 106 is calculated based on the time from transmitting the laser to receiving the laser, and the direction of movement and movement are determined based on the difference between the wavelength of the transmitted laser and the wavelength of the received laser. The speed is calculated and output to the control device 40. The control device 40 identifies each cage 18 based on information input from each laser processing device 108, 112, and also determines the position, movement direction, and direction of each cage 18.
Determine the moving speed and update the cage management information.

Thereby, the control device 40 can always grasp the state of each cage 18, and as in the first embodiment, each cage 18
The operation of the vehicle can be controlled.

In this way, in the second embodiment, the cage 1 is
8, the laser processing device 108
．． There is no need to provide a large number of 112 along the lifting passage 14 and the traversing passage 16.

In addition, in the above example, the number of cages was 8, but
The present invention is not limited to this number; for example, the number of cages may be nine or more.

In addition, in the second embodiment, the projection 104.10 is used as a reflecting means.
6 was used, but in addition to using a cube corner prism or the like that reflects the laser in the incident direction as a reflecting means, one laser processing unit that can change the laser sending angle is installed in each of the ascending and descending passages 14 and the traversing passage 16. Alternatively, the cage 18 may be identified from the angle of reflection of the reflected laser beam.

Further, in the second embodiment, only the position of each cage 18 was detected using a laser, but information can also be transmitted between the cage 18 and the control device 40 by performing laser communication.

Furthermore, when updating cage management information, the cage 18
The acceleration applied to the cage 18 may be calculated from the moving speed and time and stored as cage management information, and when controlling the movement of the cage 18, the acceleration may be controlled so as not to exceed a predetermined value.

〔Effect of the invention〕

In the invention described in claim (1), a plurality of detection means for detecting the presence or absence of a car are arranged along the elevator path, and the position of the car is determined based on the detection results of the plurality of detection means.
