Large-array antenna stacking lift control system and method

Abstract

The invention discloses a large-array antenna superimposed lifting control system, which includes a central processing unit and two-stage lifting control systems. The input and output ends of each lifting control system are connected to the central processing unit; each stage The lifting control system includes a sequentially connected proportional amplifying board, an electro-hydraulic proportional directional valve, a balance valve, a lifting cylinder, a lifting mechanism, and an absolute value angle encoder; In the control method, the absolute value angle encoder detects the lifting angle of each level of lifting mechanism and feeds it back to the central processing unit for comparison operation, and then the central processing unit provides compensation signals through the proportional amplification board, electro-hydraulic proportional reversing valve, The balance valve and the lifting cylinder control the lifting action of the two-stage lifting mechanism to maintain synchronization. The present invention not only can lift the antenna to the height of 16 meters smoothly, but also shortens the erection time of the antenna and wins precious time for the special equipment to perform tasks.

Description

technical field [0001] The invention relates to the field of radar antennas, in particular to a large array antenna superimposed lifting control system and a method thereof. Background technique [0002] The lifting control system is one of the important subsystems necessary for special equipment to perform tasks. Its main function is to send the antenna to the specified height, while bearing the self-weight from the antenna. The stability of the antenna lifting control system will directly affect whether the antenna can work normally. [0003] With the continuous development of antenna technology, increasing the height of the antenna can greatly improve the detection capability of the antenna. But for antennas with large arrays, it is difficult to lift them to a certain height. [0004] The traditional large-array antenna adopts the mast type hydraulic lifting control system of the parallel four-bar linkage mechanism. Although the lifting control system has the character...

Problems solved by technology

At the same time, due to the high center of gravity and excessive shift of the center of gravity during the movement of the lifting mechanism, the safety and reliability of the system are reduced, which in turn prolongs the erection time of the antenna

[0005] In addition, the traditional lifting mechanism will produce a sudden change in speed during the initial and in-place process, which will cause system vibration and adversely affect the system
