Abstract

The invention discloses a pulse-based multi-node gating monitoring system. The pulse-based multi-node gating monitoring system comprises a measuring device which is composed of an industrial computer, a digital I / O (input / output) card and a digital acquisition card, one end of a first cable is connected with a board card interface of the measuring device, the other end of the first cable is connected with a second aviation plug of a master unit control box, one second of a second cable is connected with a first aviation plug of the master unit control box, the other end of the second cable is connected with third aviation plugs of a plurality of slave unit control boxes, one ends of third cables are connected with 24-pin interfaces of the slave unit control boxes respectively, and the other ends of the third cables are connected with a plurality of devices to be monitored. The pulse-based multi-node gating monitoring system has the advantages that rotating speed and vibration parameters of a rotating machine can be measured effectively and precisely, the measuring precision for the rotating speed can reach to + / - 0.1Hz, and the measuring precision for the vibration parameters can reach to + / -1 micrometer; high anti-jamming capability is achieved, jamming can be resisted effectively by the aid of a metal shell, and the rotating speed and the vibration parameters can be measured accurately even in the severely-jammed site environment ; the pulse-based multi-node gating monitoring system is high in measuring response speed, instantaneity, economy and expansion capability.

Description

Technical field [0001] The invention belongs to a rotating machine speed and vibration parameter monitoring system, in particular to a pulse-based multi-node gating monitoring system. Background technique [0002] As a key parameter of rotating machinery, vibration parameters can effectively analyze the electromechanical and physical properties of the equipment. Vibration parameter monitoring of rotating machinery in industrial applications can not only effectively reflect the current operating status of the equipment, but also perform a certain degree of fault diagnosis on the equipment to find problems in time. [0003] Most of the multi-node gating monitoring systems in the prior art do not have the vibration parameter monitoring function, and the monitoring system with the vibration monitoring function has a small number of nodes and does not have good economic efficiency. Summary of the invention [0004] The present invention is proposed to solve the problems existing in the ...
