Portable Motor Fault Online Diagnosis Device

Abstract

A portable motor fault on-line diagnosis device, which includes a sensor, a signal conditioning module, an analog-to-digital conversion module, a digital signal processor and a human-computer interaction module, and the sensor receives the signal of the motor as an input of the portable motor fault on-line diagnosis device, The signal output end of the sensor is connected to the signal input end of the signal conditioning module, the signal output end of the conditioning circuit is connected to the signal input end of the analog-to-digital conversion module, and the signal output end of the analog-to-digital conversion module is connected to the digital signal input end of the digital signal processor The control signal end of the digital signal processor is connected with the control signal end of the human-computer interaction module, and the sending and receiving signal end of the human-computer interaction module is connected with the touch screen as the sending and receiving signal end of the portable motor fault online diagnosis device. The portable motor fault on-line diagnosis device of the present invention has the advantages of small size, light weight, convenient carrying and use, etc., which can detect the vibration of the motor and can also detect the electrical aspect of the motor.

Description

[0001] The application of this case is to apply for both a utility model patent and an invention patent for the invention on the same day, and the name of the invention is a portable motor fault online diagnosis device. technical field [0002] The invention relates to a portable instrument for fault diagnosis of a motor, especially adopts digital signal processing and embedded system technology. Specifically, it is a portable motor fault on-line diagnosis device widely used in power plants, steel mills, chemical plants and other occasions where motors are widely used. Background technique [0003] As the main power equipment in industrial and agricultural production, the motor is widely used because of its simple structure, low price, easy installation and ability to be used in various complex working environments. With the development of my country's economy and the continuous improvement of industrial modernization, the number of motors used in the production system and t...

Problems solved by technology

There is no device that can simultaneously detect the current spectrum and the vibration spectrum

In addition, some products claim to be able to detect online, but in fact they only play the role of collecting data, and the processing and analysis must be handed over to the host computer to complete, which is not a portable online diagnosis in the true sense.
