Abstract

The invention relates to a fast erection control system which comprises an oil supply unit, multiple stages of hydraulic cylinders, a plurality of auxiliary power branches and a main power branch, andthe auxiliary power branches and the main power branch are connected in parallel. A switching sensor, an open loop controller, a closed loop controller and a switching controller are included; each stage of hydraulic cylinder of the multiple stages of hydraulic cylinders communicates with the oil supply unit through the main power branch and one of the auxiliary power branches, and extends out step by step to complete erection of an erection arm; the switching sensor is used for monitoring the erection state of the erection arm to feed back the erection state to the switching controller in real time; the open loop controller and the closed loop controller are connected in parallel to be then connected with the switching controller in series; and the switching controller is used for selecting parameters according to the erection state of the erection arm to adjust the control state of the main power branch. The fast erection control system solves the problem that the fast erection system based on an energy accumulator type auxiliary power source is large in pressure fluctuation and long in stabilization time in the erection process.

Description

technical field [0001] The invention relates to the technical field of erection, in particular to a rapid erection control system based on an accumulator-type auxiliary power source belt switching controller. Background technique [0002] The erection time of large-scale erection equipment such as missile launching vehicles affects the rapid response capability of missiles, and then affects the survivability of missiles. [0003] In the prior art, the erecting system usually includes a single-rod hydraulic cylinder, a main power branch and an auxiliary power branch. The extension of the single-rod hydraulic cylinder is first pushed by the auxiliary power branch. At 90°, switch to the main power branch to push, so that the erecting angle of the erecting arm reaches 90°, and the erection is completed. However, the erecting speed is not adjustable, and the erecting speed is always high, resulting in low control precision of the erecting process and poor stability of the erecti...
