Between the hoistway and the car 1, an elevator landing device 2 for landing the car 1 on each floor is provided.

  The elevator landing device 2 includes a magnetic sensor 21 fixed to the car 1 and a landing plate 22 fixed to the hoistway. The magnetic sensor 21 has a base 211, a pair of descending magnetic sensor units 212 for landing the descending car 1, and a pair of ascending magnetic sensor units 213 for landing the rising car 1. doing. The descending magnetic sensor unit 212 is disposed above the ascending magnetic sensor unit 213. The landing plate 22 extends in a direction perpendicular to the wall of the hoistway to which the landing plate 22 is attached, and extends in a direction in which the car 1 moves up and down. The landing plate 22 is disposed so as to face the base portion 211 when the car 1 is landing. The end surface of the landing plate 22 facing the base portion 211 is colored in a color different from the other surface portion of the landing plate 22, for example, red. Although one landing plate 22 is shown in the figure, a plurality of landing plates 22 are provided so as to correspond to each floor.

  The car 1 is provided with a gap size inspection device (gap size inspection device for elevator landing device) 3 for measuring the gap size between the magnetic sensor 21 and the landing plate 22. The gap dimension inspection device 3 periodically measures the gap dimension between the magnetic sensor 21 and the landing plate 22. The gap dimension checking device 3 includes a camera 31 fixed to the magnetic sensor 21 and a gap dimension checking device main body 32 provided on the upper portion of the car 1. The camera 31 is arranged so that the end face of the landing plate 22 facing the base 211 is included in the photographed image. An image taken by the camera 31 is input to the gap dimension checking device main body 32. In the first embodiment, the configuration in which the camera 31 is fixed to the magnetic sensor 21 will be described. However, the present invention is not limited to this, and the gap between the magnetic sensor 21 and the landing plate 22 can be photographed. If there is, the camera 31 may be fixed at an arbitrary position of the car 1.

  FIG. 3 is a plan view showing the elevator landing apparatus 2 of FIG. The pair of descending magnetic sensor portions 212 extends from the base portion 211 toward the hoistway wall to which the landing plate 22 is attached. The pair of descending magnetic sensor units 212 is arranged such that the landing plate 22 is inserted between the descending magnetic sensor units 212. Although not shown, the pair of ascending magnetic sensor units 213 are attached to the base 211 in the same manner as the pair of descending magnetic sensor units 212. Accordingly, the gap dimension between the descending magnetic sensor part 212 and the landing plate 22 is the same as the gap dimension between the raising magnetic sensor part 213 and the landing plate 22.

  The clearance dimension between the landing plate 22 and the magnetic sensor 21 is the clearance dimension X between the magnetic sensor 21 and the landing plate 22 in the width direction of the landing plate 22 and the magnetic sensor in the depth direction of the landing plate 22. 21 and a clearance dimension Y including a clearance dimension Y between the landing plate 22.

It is a gap dimension with the plate 22. Since the gap dimension between the descending magnetic sensor unit 212 and the landing plate 22 and the gap dimension between the raising magnetic sensor unit 213 and the landing plate 22 are the same, in this example, the landing plate 22 As a measurement of the gap dimension between the magnetic sensor 21 and the landing plate 22 in the width direction, measurement of the gap dimension between the descending magnetic sensor unit 212 and the landing plate 22 will be described.

  The gap dimension Y between the magnetic sensor 21 and the landing plate 22 in the depth direction of the landing plate 22 is a gap dimension between the base 211 and the landing plate 22.

The gap dimension Y between the magnetic sensor 21 and the landing plate 22 in the depth direction is disposed within a predetermined range. After the elevator landing device 2 is installed, the gap dimension X or the gap dimension Y may exceed a predetermined range due to expansion or contraction of the building or an earthquake, so the gap dimension X and the gap dimension Y are regularly checked. There is a need.

  FIG. 4 is a block diagram showing the gap dimension checking device 3 of FIG. In the figure, a gap dimension inspection apparatus main body 32 measures a gap dimension measuring apparatus 321 that measures a gap dimension between the landing plate 22 and the magnetic sensor 21 based on an image photographed by the camera 31, and a measurement by the gap dimension measuring apparatus 321. Based on the results, a determination device 322 for determining whether or not the clearance dimension between the landing plate 22 and the magnetic sensor 21 is within a predetermined range, the measurement result of the clearance dimension measurement device 321, and the determination result of the determination device 322. And a notification device 324 that reports to the information center (external) 4 based on the determination result of the determination device 322.

  The gap dimension measuring device 321 reads a reference image that is an image of the end face of the landing plate 22 facing the base 211 when the camera 31 is photographed with the position of the landing plate 22 with respect to the magnetic sensor 21 being the reference position. I remember it. The gap dimension measuring device 321 measures the gap dimension between the landing plate 22 and the magnetic sensor 21 by comparing the stored reference image with the image taken by the camera 31.

  The determination device 322 stores information of a predetermined range that is an allowable gap dimension between the landing plate 22 and the magnetic sensor 21. The determination device 322 compares the gap dimension between the landing plate 22 and the magnetic sensor 21 measured by the gap dimension measuring device 321 with the stored information in a predetermined range, and compares the landing plate 22 and the magnetic sensor. It is determined whether or not the gap dimension with 21 is within a predetermined range.

  The storage device 323 acquires position information of the car 1 from the elevator control panel 5 that controls the raising and lowering of the car 1. The storage device 323 stores the measurement result of the gap dimension measurement device 321 and the determination result of the determination device 322 in association with the position information of the car 1.

  The reporting device 324 receives the measurement result of the gap size measuring device 321 and the determination result of the determination device 322. When the determination device 322 determines that the gap dimension between the landing plate 22 and the magnetic sensor 21 is not within a predetermined range, the alarm device 324 has a predetermined gap dimension between the landing plate 22 and the magnetic sensor 21. The fact that it is not within the range and the measurement result of the gap size measuring device 321 are reported to the information center 4.

  Next, measurement of the gap dimension between the landing plate 22 and the magnetic sensor 21 by the gap dimension measuring device 321 will be described. FIG. 5 is a view showing an image taken by the camera 31 with the landing plate 22 in FIG. 3 in the reference position, and FIG. 6 is a view of the camera 31 in a state in which the position of the landing plate 22 in FIG. FIG. 7 is a diagram illustrating an image captured by the camera 31 in a state where the position of the landing plate 22 in FIG. 5 is changed in the depth direction. When the position of the landing plate 22 with respect to the magnetic sensor 21 changes in the width direction of the landing plate 22, the position of the end face of the landing plate 22 in the image taken by the camera 31 changes. The gap dimension measuring device 321 determines the gap dimension X between the landing plate 22 and the magnetic sensor 21 in the width direction of the landing plate 22 based on the position of the end face of the landing plate 22 in the image taken by the camera 31. Measure the deviation. Specifically, the gap dimension measuring device 321 includes the position of the center portion in the width direction of the end surface of the landing plate 22 in the image photographed by the camera 31 and the center portion in the width direction of the end surface of the landing plate 22 in the reference image. The position is compared, and the deviation amount of the gap dimension X between the landing plate 22 and the magnetic sensor 21 in the width direction of the landing plate 22 is measured. Further, the gap dimension measuring device 321 has a gap between the landing plate 22 and the magnetic sensor 21 in the width direction of the landing plate 22 based on the measured deviation amount of the gap dimension X and the reference position of the landing plate 22. Dimension X is calculated. The allowable deviation amount of the gap dimension X is, for example, about several mm.

  When the position of the landing plate 22 with respect to the magnetic sensor 21 changes in the depth direction of the landing plate 22, the size of the end surface of the landing plate 22 in the image taken by the camera 31 changes. The gap dimension measuring device 321 determines whether the landing plate 22 and the magnetic sensor 21 are in the depth direction of the landing plate 22 based on the width direction size of the end surface of the landing plate 22 in the image taken by the camera 31. The amount of deviation of the gap dimension Y is measured. Specifically, the gap dimension measuring device 321 compares the widthwise dimension of the end face of the landing plate 22 in the image taken by the camera 31 with the widthwise dimension of the end face of the landing plate 22 in the reference image. The amount of change in the width direction dimension of the end surface of the landing plate 22 in the image taken by the camera 31 is measured. The amount of change in the dimension in the width direction of the end surface of the landing plate 22 in the image taken by the camera 31 and the amount of deviation of the gap dimension Y between the landing plate 22 and the magnetic sensor 21 in the depth direction of the landing plate 22 are: Because of the one-to-one relationship, the gap dimension measuring device 321 calculates the amount of deviation of the gap dimension Y based on the measured change in the width dimension. The gap dimension measuring device 321 also determines the gap between the landing plate 22 and the magnetic sensor 21 in the depth direction of the landing plate 22 based on the calculated deviation amount of the gap dimension Y and the reference position of the landing plate 22. Dimension Y is calculated. The allowable deviation amount of the gap dimension Y is, for example, about 5 mm to 10 mm.

If the gap size measuring device 321 determines in step S102 that the car 1 has not reached the floor, step S102 is repeated.

  On the other hand, when the gap dimension measuring device 321 determines that the car 1 has reached the floor in step S102, the camera 31 images the landing plate 22 (imaging process), and the gap dimension measuring device 321 images the camera 31.

Thereafter, the determination device 322 determines whether the gap dimension X between the magnetic sensor 21 and the landing plate 22 in the thickness direction of the landing plate 22 is within a predetermined range based on the measurement result of the gap dimension measuring device 321. It is determined whether or not (determination step) (step S104). When the determination device 322 determines that the gap size X is within the predetermined range in step S104, the storage device 323 corresponds to the position information of the car 1 and the determination result of the gap size measurement device 321 and the determination of the determination device 322. The result is stored (storage process) (step S105).

When the determination device 322 determines that the gap size Y is within the predetermined range in step S108, the storage device 323 corresponds to the position information of the car 1 and the determination result of the gap size measurement device 321 and the determination device 322 determine. The result is stored (storage process) (step S109).

  On the other hand, if the determination device 322 determines that the gap dimension Y is not within the predetermined range in step S108, the notification device 324 issues a notification to the information center 4 (reporting step) (step S110), and then step S109. Proceed to

  After step S109, the gap dimension measuring device 321 determines whether or not the car 1 has reached all the floors (step S111). If the gap dimension measuring device 321 determines that the floor reached by the car 1 is not all the floors in step S111, the process returns to step S102.

  On the other hand, when the gap dimension measuring device 321 determines that all floors of the car 1 have been reached in step S111, the car 1 stops (step S112), and the elevator landing device 2 is inspected using the gap dimension inspecting device 3.
