Online monitoring system

Abstract

The invention belongs to the field of an online monitoring technology, especially relates to an online monitoring system, and provides an online monitoring system capable of improving the equipment maintenance management efficiency. The online monitoring system comprises a Wien bridge, an instrument operation amplifier, a bandpass filter circuit, an AC-DC conversion circuit, a filter circuit, a low-pass filter circuit, a first amplifier circuit, a first integration circuit, a second amplifier circuit, a second integration circuit, a third amplifier circuit, a single-chip microcomputer and an encoding circuit, and is mainly structurally characterized in that the single-chip microcomputer is respectively connected with the filter circuit, the first amplifier circuit, the second amplifier circuit, the third amplifier circuit, the instrument operation amplifier and the encoding circuit, the instrument operation amplifier is connected with the Wien bridge, and the filter circuit, the AC-DC conversion circuit, the bandpass filter circuit, the low-pass filter circuit, the first amplifier circuit, the first integration circuit, the second amplifier circuit, the second integration circuit and the third amplifier circuit successively.

Description

technical field [0001] The invention belongs to the technical field of online monitoring, and in particular relates to an online monitoring system. Background technique [0002] At present, industrial enterprises have complete condition monitoring and diagnosis systems for key large-scale units. However, for some small and medium-sized key rotating equipment (such as pumps, compressors, small fans, small motors, etc.) Sexuality: The speed is low, the cost of equipment maintenance and replacement is low, and there is still no ideal online monitoring solution and equipment. Most enterprises are still in the equipment maintenance stage of offline monitoring or manual inspection and regular maintenance. However, the operation of these equipment is directly related to the production of the enterprise, which may affect the operation of large-scale units and have an important impact on the economic benefits of the enterprise. Based on this background, through the analysis of the a...

[0002]At present, industrial enterprises have complete condition monitoring and diagnosis systems for key large-scale units. However, for some small and medium-sized key rotating equipment on site (such as pumps, Compressors, small fans, small motors, etc.) Due to the particularity of their work: low speed, low equipment maintenance and replacement costs, etc., there is still no ideal online monitoring solution and equipment, and most companies still stay in offline monitoring or manual inspection and Equipment maintenance phase of scheduled maintenance

However, the operation of these equipment is directly related to the production of the enterprise, which may affect the operation of large-scale units and have an important impact on the economic benefits of the enterprise.
