Abstract

The invention discloses an accurate control system and method for synchronous jack-up main jacks for an aircraft. The control system comprises at least three main jacks and further comprises a PLC controller electrically connected with each main jack, and a control end electrically connected with the PLC controller, wherein each main jack is equipped with a servo driver, the servo drivers are electrically connected with servo motors of the main jacks, a pipeline on which the servo motors are communicated with main jack acting cylinders is further provided with a proportion valve and an electromagnetic valve, pull wire sensors are further connected between supporting heads of the main jack acting cylinders and the main jack acting cylinders, and the servo drivers, the proportion valve, theelectromagnetic valve and the pull wire sensors are electrically connected with the PLC controller. The accurate control system is advantaged in that an automatic full-machine synchronous jack-up modeis employed, labor intensity of the aircraft staff is greatly reduced, the preparation time for military aircraft maintenance is shortened, and economic benefits of civil aircrafts are improved.

Description

Technical field [0001] The invention relates to the technical field of synchronous maintenance equipment for airplanes, in particular to an accurate control system and control method of a synchronous jacking main jack for airplanes. Background technique [0002] With the vigorous development of the aviation industry, the increasing types of aircraft ground support equipment, and the higher and higher requirements for the function and performance of the equipment, the domestic aircraft with synchronous jacking main jacks can no longer meet the requirements of use. At present, the existing electrical control system of synchronous jacking main jack mainly has several problems: [0003] a) Poor synchronization accuracy; [0004] b) The functions it has cannot meet the actual needs; [0005] c) Poor reliability and tolerance; [0006] d) Complex operation and poor user experience; [0007] Therefore, the domestic and foreign countries urgently need to develop a synchronous jacking main jac...
