Problems solved by technology

This has a great impact on the operating efficiency of the elevator
The operating efficiency of the elevator is closely related to the design of the elevator speed curve. The speed curve of the elevator is directly related to the comfort level. A bad speed curve design will cause a decrease in the operating efficiency of the elevator and discomfort of passengers.

Embodiment

[0016] like figure 1 , figure 2 , the elevator car is going from floor X to floor Y, the target distance is S, and the elevator is set to run through the jerk zone ①, uniform acceleration zone ②, deceleration zone ③, constant speed zone ④, acceleration and deceleration zone ⑤, and uniform deceleration zone ⑥ and deceleration zone ⑦, set the maximum acceleration a max , the maximum operating speed v max And the running time t of each section of jerk zone ①, uniform acceleration zone ②, deceleration zone ③, acceleration and deceleration zone ⑤, uniform deceleration zone ⑥ and deceleration and deceleration zone ⑦ 11 , t 12 , t 13 , t 31 , t 32 , t 33 , the uniform deceleration zone ⑥ and the deceleration and deceleration zone ⑦ at the speed switching point P (that is, the running time t=t 11 +t 12 +t 13 +t 31 +t 32 +t 33 time) for speed switching, t is the timing from the speed curve. In this example t 剩 = t 33 .

[0017] The speed curves of each zone are as fol...

Abstract

The invention discloses an elevator speed compensation method. An elevator runs according to a scheduled speed curve before entering a speed reduction region, speed compensation is not carried out, compensation on the speed of the elevator is carried out after the elevator enters the speed reduction region, firstly the actual residual distance between the elevator and an end point when the elevator enters a set speed reduction region is acquired by the existing position correcting device of the elevator, then deviation distance between the actual residual distance and the theoretical residual distance is solved, and a speed related to the actual residual distance is compensated on the basis of a scheduled speed. When compensation on the speed of the speed reduction region is carried out by adopting the method disclosed by the invention, direct stop of the elevator can be realized, operational efficiency of the elevator is improved, elevator speed can be smoothly transited, and comfortable feeling is improved.

Description

technical field [0001] The invention relates to elevator technology, in particular to an elevator speed compensation method. Background technique [0002] During the operation of the elevator, the landing will be inaccurate due to slippage, which needs to be corrected by running at a low speed. This has a great impact on the operating efficiency of the elevator. The operating efficiency of the elevator is closely related to the design of the elevator speed curve. The speed curve of the elevator is directly related to the comfort level. A bad speed curve design will cause the decrease of the elevator operating efficiency and the discomfort of passengers. [0003] Generally speaking, the elevator speed curve includes jerk zone, uniform acceleration zone, deceleration zone, constant velocity zone, acceleration and deceleration zone, uniform deceleration zone and deceleration zone The deceleration zone is one of the necessary sections. The inaccurate landing of the elevator i...
