Based On The DSP Control Of Belt Conveyor To Protect The System

Belt conveyor is often used as transportation equipment for the mining production, inactual use, often there will be some fault, from safety and improve the production efficiencyof belt conveyor protection device is essential. With the development of science andtechnology more and more advanced protection device, using advanced sensor deviceapplication, and adding protection automatic adjustment, fault diagnosis technology morewidely..In this paper, belt conveyor deviation, over temperature, smoke, dust, the tearing failure,design the corresponding protection, there are nine kinds of fault protection, but also part ofthe fault can be adjusted automatically; failure of voice alarm and display the fault, andaccording to a plurality of belt machine operating at the same time to join the centralizedcontrol function.This paper relates to the DSP technology, computer technology and sensor technology,data acquisition, the sensor is stable and reliable; the DSP chip adopts TMS320LF2407chipproduced by TI company. Sensor collected information is transmitted to the DSP chip,through the information fusion and the set value, judging whether there is fault, the fault, andthe voice alarm, the display shows the fault type, and the corresponding control relay,automatic adjustment, sprinkler protection such as fault, fault cannot be excluded when theshutdown protection. According to the system function, this paper designs the hardware andsoftware of the.The detection sensor is more, in order to increase the detection accuracy and precision,using the information fusion technology, information fusion, after pretreatment totalinformation fusion of the results, the maximum reduce the error judgment.
