The double-motor operating state monitoring module has the advantages that the structure is simple, the installation is convenient, the cost performance is high, the functional portions can be reduced according to the integration requirement of a system, and the monitoring module facilitates seamless integration with an industrial PLC (Programmable Logical Controller), a DCS (Distributed Control System) and the like, so the monitoring module has good application and popularization value.

Description

technical field [0001] The invention relates to a solution for monitoring the operating state of a single-channel motor with reduced functions and high cost performance, in particular to a monitoring module for the operating state of a dual-channel motor, which belongs to the field of electrical engineering. Background technique [0002] Nowadays, with the improvement of living standards, people use motors more and more widely and rely more and more. In real life, the maintenance and monitoring of motor usage status is very important. The electrical transmission equipment in the foundry is mainly used for stepper motors, single-phase AC motors and three-phase AC motors. For non-frequency conversion or servo applications, the conventional methods for detecting the actual operating status or parameters of the motor itself are proximity switches, resolvers, and photoelectric encoders. device. Proximity switches use the form of pulse output to detect low-to-medium speed operati...

AI Technical Summary

Problems solved by technology

Proximity switches use the form of pulse output to detect low-to-medium speed operation and operating speed, but they are powerless to detect the state within one revolution. If subdivision is required, the number of proximity switches and the difficulty of mechanical installation will increase; most resolvers use 0-10V The voltage output form, the incremental photoelectric encoder detects the motor speed in the form of pulse output, the absolute photoelectric encoder detects the motor revolution by communication, the composite photoelectric encoder combines the incremental and absolute photoelectric encoder functions, and the resolver Compared with the photoelectric encoder, the price is high and the mechanical installation is difficult, especially where the installation space is narrow

It is rare for all conventional detection methods to visually display the corresponding data of speed and motor temperature, which is not conducive to on-site inspection and troubleshooting
