FIG. 1 is an overall view showing the configuration of the hoistway shape information generating device 1, and FIG. 2 is a block diagram showing the configuration of the hoistway shape information generating device 1.

  The hoistway shape information generating device 1 is a device that is installed on the floor surface of the pit portion 22 below the hoistway 21 and generates shape information in the hoistway 21 of the elevator 2. The hoistway shape information generating device 1 and the shape information A turntable 12 installed near the center of the generation device 11 and a laser device 13 installed on the turntable 12 are provided.

  The laser device 13 includes a light projecting unit 131 and a light receiving unit 132. When the projection start instruction is acquired, the light projecting unit 131 projects slit light in a direction perpendicular to the floor surface toward the ceiling or wall in the hoistway 21. The light receiving unit 132 receives the reflected light of the slit light projected from the light projecting unit 131 by the ceiling or wall in the hoistway 21.

  The turntable 12 has a motor 121 built therein. When a rotation instruction is input, the motor 121 is installed on the turntable 12 by rotating the turntable 12 180 degrees horizontally with respect to the floor surface. The light projection direction of the slit light by the laser device 13 is changed.

  The slit light projected from the light projecting unit 131 is designed to spread about 180 °. For example, when the slit light is projected from the center of the bottom surface of the hemispherical space, as shown in FIG. When the light projecting unit 131 rotates 180 ° in the horizontal direction, all the wall surfaces receive the light projection of the slit light at any timing during the rotation.

  The shape information generation device 11 includes a position information acquisition unit 111, a measurement information acquisition unit 112, a rotation information acquisition unit 113, and a three-dimensional shape information generation unit 114. The position information acquisition unit 111 acquires information (position information) for specifying the installation position of the shape information generation device 11. The measurement information acquisition unit 112 is configured to perform information on the light projection of the slit light by the light projecting unit 131 (light projection start time) and information on the light reception by the light receiving unit 132 (inner wall of the hoistway 21) at predetermined time intervals during the rotation operation by the motor 121. The distance information between the device 11 and each of the plurality of points irradiated with the slit light on the inner wall of the hoistway 21 is acquired as measurement information based on the received time of the reflected light from the predetermined position. The rotation information acquisition unit 113 acquires rotation information including a rotation angle by the motor 121 of the turntable 12 at predetermined time intervals. The three-dimensional shape information generation unit 114 includes the position information of the device 11 acquired by the position information acquisition unit 111, the measurement information measured by the measurement information acquisition unit 112, and the rotation information acquired by the rotation information acquisition unit 113. Then, three-dimensional shape information including dimensional information of each part in the hoistway 21 is generated.

<Operation of hoistway shape information generating apparatus according to one embodiment>
Next, processing for generating three-dimensional shape information in the hoistway 21 by the hoistway shape information generating device 1 according to the present embodiment will be described with reference to the sequence diagram of FIG. In the present embodiment, when the three-dimensional shape information generation process is performed, the elevator car 2 is moved to the upper floor, the measurer A enters the pit portion 22 below the hoistway 21, and the center portion of the floor surface. A hoistway shape information generating device 1 is installed in the vicinity.

  When a light projection start instruction by the operation of the measurer A is input in the installed hoistway shape information generation device 1 (S1), slit light spreading about 180 ° from the light projecting unit 131 of the laser device 13 is generated on the floor. Light is projected in a direction perpendicular to the surface. When the projection of the slit light by the light projecting unit 131 is started, the light receiving unit 132 receives the reflected light of the slit light projected from the light projecting unit 131 by the ceiling or wall in the hoistway 21 ( S2). Then, in the measurement information acquisition unit 112 of the shape information generation device 11, light reception by the light receiving unit 132 from light projected by the light projecting unit 131 is performed at a predetermined time interval at a plurality of points irradiated with the slit light in the hoistway 21. Each time is measured, and based on this, the distance between the device 14 and each of a plurality of points on the inner wall of the hoistway 21 is measured (S3). The larger the number of the plurality of points, the more accurately the vertical planar shape in the hoistway 21 can be recognized.

  Next, when rotation instruction information for rotating the light projection direction of the slit light by the light projecting unit 131 is input by the operation of the measurer A (S4), the motor 121 is driven and the turntable 12 is moved to the floor surface. The operation of rotating 180 ° horizontally is started (S5). Here, during the rotation operation of the turntable 12, rotation information including a rotation angle for each predetermined time is acquired by the rotation information acquisition unit 113 of the shape information generation device 11 (S6). Further, during the rotation operation, the distance measurement process with respect to a plurality of points in the hoistway 21 at predetermined time intervals by the shape information generation device 11 is continuously executed.

Is generated (S8). The three-dimensional shape information includes the position information of the own apparatus 11 acquired by the position information acquisition unit 111 and the shape information generation apparatus 11 measured at predetermined time intervals by the measurement information acquisition unit 112 during the rotation operation of the turntable 12. And the distance information between the plurality of points on the inner wall of the hoistway 21 and the rotation information acquired by the rotation information acquisition unit 113 during the rotation operation of the turntable 12. In the three-dimensional shape information generation unit 114, first, vertical plane shape information in the hoistway 21 is generated at a plurality of angles by horizontal rotation, and these are combined to generate three-dimensional shape information in the hoistway 21. Is done.

  According to the above embodiment, the hoistway shape information generating device installed in the pit portion of the hoistway rotates the slit light perpendicular to the floor surface by 180 ° in the horizontal direction with respect to the floor surface. Thus, a plurality of pieces of vertical plane shape information in the hoistway can be acquired, and shape information including the dimensions of each part in the elevator hoistway can be easily and accurately generated.
