Gate gap self-adaptive deviation rectification processing system and processing method

Abstract

The invention provides a gate gap self-adaptive deviation rectification processing system. The gate gap self-adaptive deviation rectification processing system comprises a gate gap self-adaptive sensor (1), a hoist PLC system (6) and oil cylinders (5); the gate gap self-adaptive sensor (1) detects a gate gap in real time and transmits detection data to the hoist PLC system (6); and the hoist PLC system (6) adjusts the gate gap in a self-adaptive mode by controlling the actions of the oil cylinders (5) located on the two sides of a gate. According to the gate gap self-adaptive deviation rectification processing system, the gap between the gate and a gate wall side rail plate is measured in real time at a close range, obtained gap data are compared with a gap value indirectly obtained through an opening degree sensor, no transmission and conversion error exists, and the data are more accurate; and the gate gap self-adaptive deviation rectification processing system is not affected by the precision, sensitivity and conversion error of the opening degree sensor and deformation of a gate wall civil engineering and radial gate body. The invention further discloses a processing method adopting the gate gap self-adaptive deviation rectification processing system.

Description

technical field [0001] The invention relates to the technical field of gate control, in particular to a gate gap adaptive correction processing system, and also relates to a deviation correction processing method using the processing system. Background technique [0002] In water conservancy projects, the opening and closing of generally large arc gates is realized by controlling the operation of the double-sided oil cylinders through the PLC system of the hydraulic hoist. When opening and closing the gate, in addition to paying attention to the opening of the gate, it is also necessary to ensure that the gate is not jammed during operation. [0003] In general, the jamming of the gate is mainly due to the asynchrony of the cylinders on both sides, which leads to the deviation of the movement track of the gate. When the deviation reaches a certain level, the friction between the offset gate body and the gate wall is caused, or even jammed. If jamming occurs, the gate will b...

Problems solved by technology

The above-mentioned sensors, because they cannot directly measure the gap value on both sides of the gate, or are limited by their own accuracy and the influence of the gate wall conditions, cannot truly reflect the gap value and jamming state on both sides of the gate. There is still a jamming problem when closing
