Embodiment

[0029] Such as figure 2 A specific embodiment of the circuit board assembly 2 is shown, wherein the angle between the first micro-relay I and the second micro-relay III is 135 degrees, and the angle between the reed relay II and the second micro-relay III is The angle between them is 112.5 degrees.

[0030] By adjusting the driving mechanism of the R-type waveguide switch, the protruding contact on one side of the position feedback component 3 is used to drive the second micro-relay III at 0°, and the protruding contact on the other side is used to drive the second micro-relay III at 135°. A micro relay I.

[0031] Based on the foregoing embodiments, the working principle of the present invention is described in detail:

[0032] The position feedback component 3 will stay in four state positions along with the guide rotor of the waveguide switch, which are 0°, 45°, 90° and 135° respectively. The effective part used to drive three relays can be equivalent to a pair of conta...

Abstract

The invention discloses a position state detection device for a satellite-bone R-type waveguide switch. The position state detection device comprises an upper shell, a lower shell, a circuit board component, a position feedback component and bolts, wherein the circuit board component is fixed on the upper shell; the position feedback component is connected with a hanging beam of an R-type waveguide switch guiding rotor; the R-type waveguide switch guiding rotor is fixed inside the lower shell through a bearing; two micro-relays and a dry-reed relay are mounted on the circuit board component; two pairs of magnet steels are mounted on touch spots designed on the position feedback component to form parallel magnet fields. By arranging a logic circuit of three single-pole double-throw relays, the position detection function of the satellite-bone R-type waveguide switch is realized; by adopting the position detection switch array arrangement in combination with magnetic induction and contact, the position state detection device has relatively high error tolerance capability, and the operation reliability of the satellite-bone R-type waveguide switch is greatly improved.

Description

technical field [0001] The invention relates to a rotation angle position detection device, in particular to a highly reliable space-borne R-type waveguide switch rotation angle position detection device which combines magnetic induction and mechanical contact, and belongs to the field of mechanical design. Background technique [0002] Rectangular waveguide is one of the earliest types of transmission lines used to transmit microwave signals. The transmission frequency ranges from 1GHz to over 220GHz.
