Embodiment Construction

[0015] Systems and methods are disclosed that are capable of collecting, analyzing and transmitting diagnostic information for a machine such as a motor or generator. Diagnostic information may be provided based on signals from one or more sensors configured to measure the condition of the machine or machine operating parameters (eg, temperature, vibration, humidity, etc.). In one example, an encoder device may convert machine position into an encoder signal representing the position and / or speed of an associated machine (eg, motor, generator). For example, the encoder device may be an incremental encoder. The encoder device may also include pre-processing configured to perform some signal processing or calculations on the machine sensor information and provide diagnostic information. Pre-processing may be performed locally at the machine where the encoder is installed, and / or remotely at the system (eg, controller, computer) that processes the encoder's position and diagnost...

Abstract

A system includes an encoder that monitors a machine and generates an encoder output signal indicative of at least one of motion or position of the machine. The combiner may be configured to receive the encoder output signal from the encoder and to receive machine diagnostic data from at least one other sensor. A combiner may combine the machine diagnostic data with the encoder output signal to provide a combined signal including the machine diagnostic data synchronized with at least one of motion or position of the machine. The output stage provides a combined signal to a remote system.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application 61 / 894,177, filed October 22, 2013 and entitled "MACHINE DIAGNOSTIC ENCODER," which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to an encoder and an encoding method that can process and transmit diagnostic information for a machine. Background technique [0004] Large-scale manufacturing operations such as paper or steel production often employ very large machines, including electric motors or generators. Such machines are often controlled by remote systems which may be located at a remote distance from the machine. As an example, to control a machine, an encoder is typically mounted on or coupled to a machine shaft to detect the position and / or speed of the machine. In some circumstances, due to the long distance between the controller and the machine, it can be an expensive proce...
