Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] In this embodiment, the Zhu controller adopts single-chip microcomputer ATMEGA162 as the control core, and uses the programmable logic chip XC9536 as the logic control component. The on-site vibration value display can realize the on-site liquid crystal display of vibration data, and the data prompt and parameter setting process are prompted in Chinese. The setup process is intuitive and straightforward. At the same time, the vibration alarm threshold, alarm delay time, etc. are set on site. When the monitoring value exceeds the alarm setting range, an alarm or trip signal is given to directly protect the unit.

Abstract

The invention discloses a vibration detecting protecting device, which comprises a main controller for collecting, processing and converting vibration signals into real-time vibration data and outputting alarm signal and / or jump signal according to the real-time vibration data, a sub controller connected with the main controller for reading real-time vibration data and displaying the data on a liquid crystal display unit, and a liquid crystal display unit connected with the sub controller for displaying the real-time vibration data. the invention uses the liquid crystal display unit to on-site display the real-time vibration data obtained by the main controller and can realize on-site real-time detection on the vibration of object machine, thereby improving projection on the machine and improve machine safety. The invention has high integrality, small volume, strong interference resistance, high reliability and simple installment.

Description

technical field [0001] The invention relates to the field of vibration monitoring and protection, in particular to an intelligent and miniaturized vibration transmission and protection device and detection method capable of simultaneously realizing on-site liquid crystal display mode transmission and output. Background technique [0002] Rotating mechanical equipment, such as steam turbines, water turbines, compressors, gas turbines, blowers, motors and pumps, etc., a variety of main mechanical parameters related to equipment safety need to be continuously measured and monitored, such as speed, shaft vibration / swing, tile vibration / machine Frame vibration, differential expansion, eccentricity, axial displacement and casing expansion and other parameters. At present, the single-channel or dual-channel instruments that monitor the vibration status of small and medium-sized units have no on-site display or use digital tubes to display. It is not convenient for on-site observat...
