Backplane bus type structure of vibration monitoring and protecting device and communication control method thereof

Abstract

The invention provides a backplane bus type structure of a vibration monitoring and protecting device and a communication control method of the backplane bus type structure. The backplane bus type structure of the vibration monitoring and protecting device comprises a monitoring and protecting device backplane and a monitoring and protecting device function module. The monitoring and protecting device backplane consists of a backplane bus and a plurality of bus slots. The backplane bus is simultaneously connected to the bus slots. Function modules in the monitoring and protecting device function module are respectively and correspondingly connected with one of the bus slots, so that the communication is realized by the backplane bus. The invention provides a backplane bus type vibrating monitoring and protecting device and a communication control method among the internal function modules of the backplane bus type vibration monitoring and protecting device, so that the full-period synchronous collection of real-time large-capacity full-waveform data of mechanical vibrating signals, the vibration fault characteristics extraction, the monitoring and protection, and the online analysis and diagnosis are realized; and the hot plugging and the plug-and-play of the modules are realized. Therefore, the defects that the traditional devices or products are difficult to realize the real-time processing of the large-capacity full-waveform data are overcome.

Description

technical field [0001] The invention belongs to the fields of mechanical vibration signal monitoring and protection and equipment failure analysis and diagnosis, and in particular relates to a communication and control method for internal modules of a backplane bus type vibration monitoring and protection device. Background technique [0002] The rotating machinery monitoring protection and fault analysis and diagnosis device is an important tool to ensure the safe, stable and efficient operation of the equipment. It has become an urgent need for enterprises to realize condition-based maintenance and predictive maintenance of equipment on a basic basis. The traditional state monitoring and alarm device with monitoring instruments as the main body can monitor the vibration, temperature, pressure, flow and other information of the equipment online, and give an alarm prompt to the abnormal monitoring parameters according to the manually set alarm threshold until the interlock s...

Problems solved by technology

This invention also only monitors characteristic quantities such as vibration peak value and intensity, without synchronous acquisition and analysis of waveform data. Also due to the limitation of RS485 communication rate, it is difficult to realize real-time monitoring, processing, analysis and diagnosis of large-capacity full-waveform data
