Running state monitoring module of single-way motor

Abstract

The present invention relates to a running state monitoring module of a single-way motor. The running state monitoring module of the single-way motor comprises a power supply conversion module, a signal acquisition module and a signal conditioning module. The power supply conversion module is configured to convert a wide voltage input separation stabilized voltage supply to a power supply required by a differential voltage comparator through a LDO voltage stabilizer; the signal acquisition module is configured to fasten a hose clamp photoelectric encoder at a motor shaft or a shaft coupling, the hollow and entity edge part of the encoder is arranged in the groove of a groove-type optocoupler; and the signal conditioning module is configured to convert frequency signals of 0 to 1KHz to direct current voltage signals of 0 to 10V, convert voltage signals of 0 to 10V to current signals of 4 to 20mA for outputting, externally provide an on-off output, and indirectly indicate the ratio of the current speed and a rated speed on a LED. The installation is easy and the cost performance is high, and the running state monitoring module of single-way motor is convenient for performing seamless integration with systems such as an industry PLC, a DCS and the like, and has a good application and promotion value.

Description

technical field [0001] The invention relates to a single-channel motor running state monitoring solution with cuttable functions and high cost performance, in particular to a single-channel motor running state monitoring module, 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 operation and operating speed, but...

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

In summary, it is rare for all conventional detection methods to visually display the data corresponding to the rotational speed, which is not conducive to on-site inspection and troubleshooting
