Description

Technical Field

[0001] The present invention relates to the technical field of elevator control, in particular to an elevator floor data acquisition device and a floor detection method thereof. Background Art

[0002] At present, elevators have been popularized in various office buildings, shopping malls, residential areas and other buildings, saving time, being convenient and fast, and providing great convenience for people. When the elevator is running, it is necessary to accurately and reliably locate each floor that needs to be stopped, so that the elevator can stop at each floor with millimeter accuracy. Because the floor height of some buildings is not fixed, and the ground is not tiled in time after installation, the parking position of the elevator car before and after tiling is also different. In the prior art, such as CN112061915B, a non-intrusive elevator floor detection method is disclosed, which divides the total floor height by the total number of floor intervals to obtain the average height between adjacent floors. Taking the ground floor as the reference, the pressure difference between the starting floor and the current floor is measured and converted into the movement distance to calculate the floor where the current elevator is located. This method is only applicable to buildings with the same floor spacing, and it is necessary to ensure that the air pressure in the elevator shaft is sufficiently stable, so there are certain limitations.

[0043] A floor detection method of an elevator floor data acquisition device comprises the following steps:

[0044] S1. Place the first fixed bracket 3 in the car, adjust the height, and adjust the position of the through-beam edge measurement sensor transmitter 7 to a vertical state, and record the distance between the through-beam edge measurement sensor transmitter 7 and the bottom of the first fixed bracket 3;

[0045] S2, set the second fixed bracket 4 at the floor door, adjust the height to be the same as the first fixed bracket 3, that is, the distance between the through-beam edge measurement sensor receiver 10 and the bottom of the second fixed bracket 4 is consistent with the distance in S1; and adjust the position of the through-beam edge measurement sensor receiver 10 to a vertical state, and wirelessly connect the communication module 83 to the main controller 1;

[0046] S3, adjust the direction of the first fixed bracket 3 so that the light of the linear laser pointer 13 is aligned with the middle of the fixed tube 2 43, and adjust the direction of the second fixed bracket 4 again so that the light of the linear laser pointer 2 12 is aligned with the middle of the fixed tube 1 32, so that the emitting surface of the through-beam edge measurement sensor transmitter 7 and the through-beam edge measurement sensor receiver 10 are in the same vertical plane;

[0047] S4, the distance between the center of the linear laser pointer 13 and the bottom of the first fixed bracket 3 is set to a, and the light of the linear laser pointer 13 is located at the scale line value b. If a>b, the value of ab is input through the input and display module 84 and the car 2 is raised by the distance; if a<b, the value of ba is input through the input and display module 84 and the car 2 is lowered by the distance;

[0048] S5. Through the operation of S4, the distance between the car and the floor is further reduced. The distance must be less than the range of the through-beam edge measurement sensor. The through-beam edge measurement sensor transmitter 7 is started. The through-beam edge measurement sensor transmitter 7 generates a light curtain with a width of c. The width of the light curtain is a fixed value. The width d received by the through-beam edge measurement sensor receiver 10 is recorded. The value of cd is input through the input and display module 84 to make the car 2 rise or fall. The moving distance is the value of cd. The main controller 1 stores the position as the floor position.

[0049] S6, the positions of other floors are determined according to steps S3-S5.

[0050] In step S5, if the light curtain received by the through-beam edge measurement sensor receiver 10 is located in the lower half, the car 2 descends, otherwise the car 2 ascends.

[0051] After step S5, if the floor needs to be constructed and tiled later, a preset floor tile position and a height stake are set on the floor surface, and the distance between the height stake and the floor surface is measured by a laser rangefinder 11, and the distance is stored in the main controller 1. After the floor tiles are laid, the original floor position plus the distance value is the floor position after the floor tiles are laid. The laser rangefinder 11 is used to determine the distance of the tile laying lift, thereby avoiding errors caused by uneven floor surfaces and improving accuracy.
