[0004] In view of the above analysis, in view of the shortcomings of the multi-stage hydraulic cylinder-based erecting device, such as the impact of changing stages, the hydraulic system is complicated, and there are leaks, etc., the present invention proposes a multi-stage electric cylinder-based erecting device. The control system and control method adopt the multi-stage electric cylinder as the actuator to push the erecting device for erecting, which has the advantages of simple composition, fast response and good dynamic performance

Embodiment
[0041] The specific steps of a method for erecting control based on multi-stage electric cylinders are:
[0042] The first step is to build an erection control system based on multi-stage electric cylinders
[0043] The erecting control system based on multi-stage electric cylinders includes: computer, data acquisition card, motion control card, multi-stage electric cylinder block, motor, motor driver, multi-turn photoelectric encoder, power supply, angle sensor, and erecting device.
[0044] The computer is used for data calculation and provides an installation environment for data acquisition cards and motion control cards. The data acquisition card is installed in the computer and is used for collecting angle data of the angle sensor. The angle sensor is used to measure the angle of the erecting device. Motion control cards are used for motor control. The multi-stage electric cylinder block is used to drive the erecting device to realize erecting or returning to leveling...

The invention discloses an erection control system based on a multistage electric cylinder, and the system comprises a multistage electric cylinder device, a data collection control device, a multi-turn photoelectric encoder, an angle sensor, and an erection device. The invention also provides an erection control method employing the system. The method comprises the steps: carrying out the planning of the erection angle, the erection speed and the pushing force according to the erection time, the erection process acceleration requirements and the load conditions, and controlling the multistage electric cylinder device to make linear movement to drive the erection device to erect. The multistage electric cylinder is used as the execution mechanism which pushes the erection device to erect. The multistage electric cylinder is not provided with an oil tank and a hydraulic pipe, so there is no leakage and venting phenomenon and no stage exchange impact, thereby ironing out the defects of a multistage electric cylinder erection device. The multistage electric cylinder is applied in the erection device, so the system is simple in structure, is high in response speed, is high in precision, and has no stage exchange impact.
Description
technical field [0001] The invention relates to the field of erection control, in particular to an erection control system and control method based on multi-stage electric cylinders. Background technique [0002] The missile launching vehicle erects the missile to a set angle through the erecting device, and the actuator of the erecting device generally adopts a hydraulic cylinder, especially a multi-stage hydraulic cylinder. During the erecting process of the multi-stage hydraulic cylinder, there is an impact of changing stages, which causes the erecting device to shake. In addition, the hydraulic system has many and complicated components, and the hydraulic pipeline has leakage, emission, leakage. [0003] Although in the patent No. 201510152094.9, the erecting device adopts to reduce the erecting speed before the stage change point during the erecting process, and then accelerate the erection after the stage is changed smoothly, but there are disadvantages of longer erec...
