Multi-encoder fault diagnosis and remote measurement system and monitoring method thereof

Abstract

The invention provides a multi-encoder fault diagnosis and remote measurement system and monitoring method thereof and belongs to the technical field of photoelectric encoder measurement, and aims tosolve a problem that remote measurement cannot be realized in real time in the prior art. A plurality of encoder units are connected with multiple encoder photoelectric signal processing systems and analysis treatment is performed on moire fringe photoelectric signals and angle measurement information is output. The encoder photoelectric signal processing systems transmits received moire fringe photoelectric signal sampling data and the output angle measurement information to a master control computer through a relay station. Each encoder photoelectric signal processing system is provided witha temperature sensor which transmits collected temperature information to the master control computer. The master control computer receives the moire fringe photoelectric signal sampling data, the output angle measurement information and the working temperature information transmitted from the relay station and directly controls and regulates photoelectric signal parameter information of each working encoder unit and monitors the measurement condition. The power module is connected with the multiple encoder photoelectric signal processing systems, the relay station and the master control computer.

Description

technical field [0001] The invention belongs to the technical field of photoelectric encoder measurement, and in particular relates to a multi-encoder fault diagnosis telemetry system and a monitoring method thereof. Background technique [0002] A photoelectric encoder is a device that converts the measured precision angle into a digital quantity. It is an important digital angle sensor that can measure the angle rotated by the connecting shaft in real time, and is widely used in servo systems for oil exploration, mobile robots, vehicles, aircraft, and small satellites. However, due to the influence of environmental factors, device life, mechanical alignment deviation and other factors in the working process of the photoelectric encoder, and because multiple photoelectric encoders will be used in a servo system, how to work on a certain photoelectric encoder unit in work? Real-time monitoring and diagnosis of the state, how to reduce the impact of faults on the accuracy of...
