Development Of Vibration Monitoring System For Shearer

In this paper, the electrical traction shearer was taken as research object, combined withthe signal acquisition technology、bus communication technology and embedded technology,a monitoring system of shearer based on DSP was designed, aiming to realize the vibrationsignal acquisition、storage and communication of shearer and judge the work situation.The system includes signal acquisition module, control module, communication bus anddata storage modules. TMS320f2812digital signal process as the core of hardware simplifiedthe design of peripheral circuits with the integrated enhanced eCAN controller, SPI and SCIinterface. The communications between the devices of shearer were guaranteed bycommunication bus. The vibration signal of shearer stored by data storage module providesaccurate documents for the research of failure mechanism. In side of software, the program ofsignal acquisition, communication and storage were designed. And for the reason ofhigh-voltage equipment in coal mining, more anti-jamming measures were taken fromhardware and software.By testing at laboratory, the result show that the system can realize the basic functions ofshearer monitoring system. And with the characteristics of small volume, low consume andstrong ability of data processing and anti-interference, as well as high testing precision, withbetter application prospects for the requirement of huge data storage.
