An intelligent online monitoring and protection device

Abstract

The invention provides an intelligent online monitoring protection device which comprises an upper computer, a display module, a communication management module, a rotation speed detection module, a key phase module, at least one vibration displacement / speed / acceleration monitoring module, a relay warning protection module and a communication back plate. A back plate bus is arranged on the communication back plate, the communication management module receives original data detected and transmitted by all the function modules and extracts characteristic data, concentrated storage and management are conducted, comparison judging is conducted on the characteristic data and a pre-set threshold range, and the threshold range reflects equipment operation data under the normal state of equipment. The relay warning protection module conducts warning through sound and / or optical signals on the basis of a judgment result of the characteristic data from the communication management module. The intelligent online monitoring protection device is wide in application range, high in data transmission speed, comprehensive in monitoring parameter and good in monitoring real-time performance, multiple channels are provided, the performance of a processor is high and a fault diagnosing function is achieved.

Description

technical field [0001] The invention belongs to the technical field of intelligent instruments and meters, in particular to an intelligent online monitoring and protection device for equipment. Background technique [0002] The equipment system of modern industrial production has the characteristics of continuous high speed and high automation program. When accidents, abnormal states, unexpected shutdowns and other unforeseen failures occur, they often cause huge losses, and they cannot be repaired in a short time. [0003] During the operation of equipment, sporadic failures and lifetime failures usually coexist. How to reasonably and predict these failures in advance and eliminate possible dangers is the key to prolonging the service life of equipment and reducing losses caused by downtime. [0004] To this end, a variety of monitoring equipment and corresponding methods have been proposed in the prior art to monitor the operating status of the equipment. When an abnormali...

Problems solved by technology

But its disadvantages are that it can only monitor the tile vibration signal, the monitoring parameters are single, and the monitoring channels are few; only the single-chip microcomputer is used for data processing, and the processing ability is weak; the serial port is used for data transmission, and the transmission efficiency is low; remote monitoring and fault diagnosis cannot be performed.
