Online type real-time vibration detecting device based on ATOM and ARM

Abstract

The invention provides an online type real-time vibration detecting device used for detecting of device running states. The online type real-time vibration detecting device is developed based on the burgeoning Intel ATOM platform and the mature ARM embedded technology. According to the online type real-time vibration detecting device, firstly data acquisition processing is performed through an analog to digital (A / D) module on the ARM platform, vibration analog signals are translated into digital signals, and then the digital signals are transmitted to the ATOM platform through a serial port, data after spectral analysis are displayed on the platform by the utilization of a graphical interface, and diagnosis can be performed conveniently. The online type real-time vibration detecting device has the advantages that manual routing inspection is not required, working efficiency is improved, instantaneity is good, a human-computer interaction interface is good, processing capability is strong, and the online type real-time vibration detecting device is simple and easy to use, and applicable for device vibration detection under hostile environments.

Description

technical field [0001] The invention relates to an on-line mechanical vibration detector for detecting the operation status of equipment. Background technique [0002] At present, the diagnosis of mechanical faults at home and abroad mostly adopts vibration diagnosis, which can be roughly divided into the following four categories: [0003] 1) The traditional on-line detector integrates advanced computer technology, sensor technology and network technology, and has the ability to predict failures in the early stage. However, due to the complex structure of the system, cumbersome operation and high cost, the application is limited. [0004] 2) The traditional off-line detector has the characteristics of wide application range and the ability to diagnose and analyze various equipment, and is a good supplement to the traditional on-line detector; however, due to its large size and inconvenient portability, its real-time performance is poor. [0005] 3) Hand-held data collecto...

However, due to the complex structure of the system, cumbersome operation and high cost, the application is limited.

[0004] 2) The traditional offline detector has the characteristics of wide application range and the ability to diagnose and analyze various equipment, and is a good supplement to the traditional online detector; however, due to its large size and inconvenient portability, its real-time performance is poor

This type of system can make full use of the advantages of strong control capability of the front-end CPU and the powerful and fast data processing capability of the back-end CPU, and can complete digital filtering of vibration signals, time-domain feature detection, and frequency-domain feature detection, but lacks friendly man-machine The interactive interface also lacks effective data management and storage functions, and complex multi-tasking processing will be difficult

[0007] The existing online operation is complicated and expensive; the handheld lacks a human-computer interaction interface, and it cannot detect mechanical failures in the operation of the equipment at any time online, especially when the working environment of the equipment is harsh and human resources are limited. restricted

Therefore, the safe operation of mechanical equipment cannot be guaranteed, and it is easy to cause damage to mechanical equipment and bring serious economic losses to the enterprise.
