A Space Flying Net Closing Controller and Control Method

Abstract

The invention discloses a space flying net closure controller and a control method, comprising a battery interface module, a motor interface module, an external interface module, an optocoupler isolation module, a power supply voltage stabilization module, a single-chip microcomputer module, a temperature detection module, an acceleration detection module, a voltage Composed of a detection module and a motor control module, the single-chip microcomputer module plays the role of collecting the voltage signal of the battery, the ambient temperature signal, and the acceleration signal flying to the capture device, communicating with the satellite platform, and controlling the work of the motor; through the control of the motor The advantage of realizing the closing control of the flying net is that the overall structure is simple and small, and it can be placed inside the flying net capturing device to control it. It can communicate with the satellite platform, and can change and re-bind parameters such as closing time at any time; it provides two separate detection methods and closing trigger methods, with high timeliness and reliability.

Description

technical field [0001] The invention belongs to the technical field of aerospace payloads, and specifically relates to a space flying net closing controller and a control method. Background technique [0002] Space flying net capture is to launch a flying net made of flexible thin ropes to the target, wrap the target through the flying net, and then tighten the opening of the flying net by the closing mechanism to prevent the target from leaving, so as to achieve the capture of the target . [0003] During the capture process, when to close the mouth has a greater impact on the capture effect. If the mouth is closed too early, the net mouth will be tightened before wrapping the target, resulting in capture failure; Rebound, make the target out of the flying net, resulting in unsatisfactory capture effect or even capture failure. Therefore, it is very important to start the closing mechanism at the right moment, and good control is required for the start and stop of the clo...

AI Technical Summary

Problems solved by technology

ROGER flying net closing controller: the timing closing is triggered by a spring switch. Since the closing task parameters are set in advance before the ground launch, it is difficult to adapt to the influence of uncertain factors such as the capture distance and launch speed when the flying net is captured; it does not have self-testing Function and communication function, the system status cannot be pre-checked before launch; its battery cannot be charged on-orbit, which limits the life on-orbit
