Three-channel shifter and shifting method thereof

Abstract

The invention discloses a three-channel shifter and a shifting method of the three-channel shifter. The three-channel shifter comprises a stator (1), a rotor (2), a locating block (3), a first locating support (4), a second locating support (5), a first electromagnet (6), a second electromagnet (7), a phototube (8), a phototube base (9), a first travel switch (10), a second travel switch (11), a photoelectric encoder, a controller (19) and a driving device (20). Compared with a three-channel shifter enabling a rotor to be directly driven through a motor in the prior art, the three-channel shifter has the advantages that the rotor is braked and located through the method that the locating block is attracted by the electromagnets, the reciprocating approaching process of braking and locating of the rotor is avoided, the braking and locating time of the rotor is shortened, the position of the rotor can be locked through the attraction of the electromagnets, the locating accuracy of the rotor is improved, and therefore the speed and the accuracy of channel shifting are improved.

Description

technical field [0001] The invention relates to the technical field of switching devices, in particular to a three-channel switching device and a switching method thereof. The three-channel switching device is suitable for positioning star map simulators. Background technique [0002] During some navigation and homing flights, the homing aircraft needs to perform starlight correction to correct the accumulation of inertial navigation errors caused by long-term flight, so that the aircraft can finally fly along the predetermined orbit correctly, and smoothly realize the handover of middle and final guidance . The simulation system needs to provide navigation star simulation for starlight correction and target simulation for terminal guidance. In this process, whether the position and optical characteristics of the navigation star and the target can be simulated determines the final simulation accuracy. [0003] In these hardware-in-the-loop simulation experiments, in order ...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the disadvantages of the channel switching device in the prior art are: the braking and positioning time of the rotor is long, and the positioning accuracy of the rotor is low, resulting in a slow channel switching speed, and the position of the rotor cannot be locked. Dead, the positioning accuracy of channel switching is low, which cannot meet the channel switching requirements of the positioning star map simulator
