Method and device for replacing rotating platform signal slip ring

Abstract

The invention discloses a method and a device for replacing a channel switching signal slip ring. The device comprises a data acquiring and emitting unit and a data receiving and recovering unit; a data acquisition module of the data acquiring and emitting unit acquires an analog signal of a tested platform product, processes the analog signal and outputs a digital signal to a radio frequency emission module; the radio frequency emission module transmits the digital signal to a remote data receiving and recovering unit; a radio frequency receiving module of the data receiving and recovering unit outputs the received digital signal to a data recovering module; and the data recovering module processes the digital signal and outputs the analog signal of the tested platform product. Through the method, the analog signal of the tested platform product is acquired and processed into the digital signal, the digital signal is remotely transmitted and recovered, and the analog signal of the product is output; in the replacement method, the signal acquisition and recovery technology is adopted and the signal quality can be improved; and the replacement device is easy to maintain and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to data acquisition and data recovery technology of turntable signals, in particular to a replacement method and replacement device for turntable signal slip rings. Background technique [0002] The turntable is based on cybernetics, similarity principle, system technology and information technology, and uses computers and special physical equipment as tools to provide special equipment for test benches for aircraft, marine aircraft and other experiments. It has the advantages of good controllability, safety, and is not restricted by weather conditions and airspace venues. It is widely used in aviation, aerospace, navigation and other national defense fields. Due to the spin of many tested mechanisms, the signal cannot be transmitted normally. The application of conductive slip rings solves this problem. However, conductive slip rings are mechanical components, which bring mechanical friction noise during signal transmission; cond...
