Embodiment Construction
[0047] The following combination figure 1 and 2 , to describe in detail the specific embodiments of the present invention.
[0048]The so-called "electric curtain" consists of a series of parallel electrodes placed about 1 centimeter apart and fed with an alternating current. Delaying the start of current flow for each successive electrode causes the electromagnetic field of each electrode to be out of phase with that of the adjacent electrode, and the interaction changes very rapidly, moving in 2 directions along the wire. But in order to provide the same alternating flow potential at all parallel electrodes simultaneously, each successive electrode delays the start of the flow potential. This slight delay makes each plate have a different electromagnetic field than its neighbors, creating an electromagnetic wave that creates an electromagnetic wave that repeatedly moves horizontally across the plates, and the moondust particles move up under the action of this electromagne...

The invention relates to an automatic electric curtain dust-removal system for a moon landing device; and the method has the characteristic of an "electric curtain" theory. The system is composed of adust removal function board module, a computer module, an I / O circuit module and a silicon controlled rectifier module. With combination of the electric curtain dust removal technology and the automatic control technology, the automatic electric curtain dust removing of the moon landing device is realized by using an automatic dust removing system, so that the internal electrical energy consumption of the moon landing device is reduced; and automatic control of electric curtain dust removal is realized. Besides, the method has advantages of high reliability and stability; and the dust removing need of the moon landing device is met.
Description
technical field [0001] The invention relates to an automatic control system and method suitable for an automatic electric curtain dust removal system. Background technique [0002] The whole world is setting off a new wave of lunar exploration. Countries such as the United States, Japan, the European Space Agency, Russia, and India have formulated lunar exploration programs. my country's Chang'e lunar exploration program is also proceeding in an orderly manner. The surface of the moon is a thick layer of tiny particles formed due to long-term environmental effects. The average diameter of the particles is 40-130 μm, which we call moon dust. Due to the moon's low gravity and near-vacuum conditions, these tiny particles are easily disturbed by natural or human activities and become suspended in the air. Fine moon dust particles have a high specific surface area and insulation properties. Under the effects of high temperature, strong radiation environment and various contact a...
