Problems solved by technology

[0004] For the first method, the barometer has a large error in judging the floor. The reason is that the air pressure does not change significantly within a small height difference. The atmospheric pressure (standard atmospheric pressure) at sea level is 1.01325*10^5Pa , while the height near sea level rises by 10m, the atmospheric pressure drops by 100Pa, and the height of a floor is generally about 3-5m, so the air pressure change is not obvious when the elevator crosses floors, and the error is large
[0005] For the second method, it is cumbersome to install timers and counters at the elevator pulleys, the degree of difficulty is high, and the operation is complicated
That is, although the method of directly measuring the displacement by installing a timer and a counter at the elevator pulley is accurate, the operation is too complicated, especially for an elevator that has been installed and put into use, the risk of refitting it is too great, and it is easy to cause damage.

Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] like figure 1 Shown, a kind of judgment method of elevator moving floor of the present invention, its step comprises:

[0045] Step S1: Obtain the real-time acceleration a of the elevator;

[0046] Step S2: Obtain the instantaneous speed v of the elevator according to the real-time acceleration a;

[0047] Step S3: Calculate the moving distance h of the elevator:

[0048] v=v 0 +(a-g)×Δt (1)

[0049]

[0050] Among them, v 0 , h 0 are the speed and moving distance of the elevator at the last moment, a is the measured acceleration, g is the local gravity acceleration, and Δt is the sampling time interval.

[0051]Step S4: when the elevator is stationary, calculate the number of elevator floors n=[h÷H]+n 0 , which has rounding operation, n 0 Represents the cumulative value of the recorded moving floors, H represents t...

Abstract

The invention discloses a method for judging moving floors of an elevator. The method comprises the steps that S1, the real-time accelerated speed a of the elevator is obtained; S2, the instantaneousspeed v of the elevator is obtained according to the real-time accelerated speed a; S3, the moving distance H of the elevator is calculated; and S4, when the elevator is static, the number of the moving floors of the elevator n=[h / H]+n0 is calculated, wherein rounding operation is conducted, n0 represents the recorded accumulated value of the moving floors, H represents the average height of one floor, and then h0 and h are reset to wait for the next operation process. The method for judging the moving floors of the elevator has the beneficial effects of being simple in structure, wide in application range, high in judgment precision and the like.

Description

technical field [0001] The invention mainly relates to the technical field of elevator control, in particular to a method for determining a moving floor of an elevator. Background technique [0002] The judgment of the moving floor of the elevator is to judge the number of floors the elevator moves during operation, and provide reference for the moving distance of the elevator for the elevator maintenance personnel. Existing elevator controllers cannot be changed, and the elevator system itself does not provide information on the moving distance of the elevator. The moving distance is just an important reference indicator for whether the elevator needs maintenance. [0003] There are generally two ways to detect the moving distance of the elevator in the traditional technology, that is, the technology of using the air pressure sensor to measure the floor, or installing a timer and a counter at the elevator pulley to measure the displacement of the rope. [0004] For the fir...
