Abstract

The invention discloses a multi-oil-cylinder synchronous traction control system and method applied to the marine engineering field. The synchronous traction control system comprises M jacks for achieving the traction purpose, M displacement sensors for monitoring the traction displacement amount of the M jacks and a programmable controller module for receiving output signals of the M displacement sensors, wherein each jack is provided with an independent oil cylinder. The method comprises the steps that firstly a programmable controller conducts arithmetic average operation on the received M displacement signals, and thus a displacement mean value is obtained; then, the difference value between each displacement signal and the displacement mean value is calculated out; finally, the corresponding jack is adjusted according to each difference value; the signal output terminals of the M displacement sensors are electrically connected with the I / O terminal of the programmable controller; the analog output terminal of the programmable controller is connected with the oil pressure system of each jack; the oil pressure systems control the opening of a traction oil cylinder servo valve for achieving control over the jack traction rate.

Description

technical field [0001] The invention relates to traction equipment for marine engineering, in particular to occasions where the speed precision is high in the traction process, the structure to be towed is a super-large structure, and synchronization is required in the traction process. Background technique [0002] With the development of offshore oil exploration and development, the development sea area is gradually extending from shallow sea to deep sea, and the construction scale of jackets, platform modules, etc. more than tons. Traditional traction equipment can only rely on manual control of the synchronization during the traction process, the synchronization effect is poor, and the control accuracy of the traction speed cannot meet the needs of large-scale structure traction. Therefore, it is particularly important to design and develop a synchronous control system for traction equipment cylinders. Contents of the invention [0003] The technical problem to be sol...
