Design of scraper conveyor monitoring device based on PLC

A monitoring device was developed after analyzing the characteristic andcurrent research status of domestic scraper conveyor.There have monitor master and monitor slave,the monitor slave adopted PLC(Programmable Logic Controller) technology,instant cable is used for the connection between sensors and Onboard monitor slave,the monitor master adopted the industrial panel PC running IFIX software,make use of the Profibus technology to realize the information transmission among monitor slave and monitor master.Finally,the experiment suitable for the underground conditions demonstrated that the scheme of scraper conveyor monitoring device is correct.
