On-line state monitoring system for photoelectric composite slip ring

Abstract

The invention discloses a state on-line monitoring system for a photoelectric composite slip ring, and the system comprises an optical communication state monitoring module which is disposed in an optical transmitter and receiver, and is used for monitoring the optical signal communication state in the optical transmitter and receiver; the data link monitoring module is installed on the outer side of the stator end of the slip ring and adopts a non-contact sensor to collect data signals and power signals of the input end and the output end of the slip ring; the processing module is used for summarizing information acquired by the optical communication state monitoring module and the data link monitoring module, packaging the information into a data packet, transmitting the data packet to the display terminal through the network transmission module, and connecting the optical communication state monitoring module and the data link monitoring module; according to the invention, comprehensive online real-time monitoring of power electric signals, data electric signals and optical signals can be realized, non-contact coupling of a detection system and a slip ring system is realized through non-contact detection, interference to the slip ring and influence of external interference on an acquisition system are avoided, and the system has the advantage of high reliability.

Description

technical field [0001] The invention relates to the technical field of automatic monitoring, in particular to an on-line monitoring system for the state of a photoelectric composite slip ring. Background technique [0002] As the core component of the rotating transmission system, the slip ring is responsible for the conduction and transmission of power and data signals (electrical signals, optical signals, etc.). Due to its functional characteristics, its installation position is where the rotating mechanism and the non-rotating mechanism connect. The space is generally very small, and if the transmission system fails, it is very difficult to determine whether it is the problem of the slip ring or the entire transmission link. In addition, if it is necessary to further determine whether it is the problem of the slip ring itself, it is usually necessary to remove the slip ring from the entire system. It usually takes a lot of manpower, material resources and time to separate...
