Infrared Sensor In The Belt Conveyor Safety Alert Systems Research And Application

Belt conveyer,which is used mainly to transporting lumpish,granular,or loose materials and pieces of goods.is a kind of continuous conveyance with tractive items,so it is applied widely in the industry production. The aim of this item is to solve the safety of the belt conveyer in the selector of the Pangang Group. The safety and control system could measuring, alarming and controling automatically.This system is composed of the infrared transducer unit, speech alarm system, alarm, control unit and others. Infrared transducer examines directly the body and sends out electrical signal similar to sine wave. The signal handling and analyzing unit dispose of the sensor's output signal by amplifying, plasticisering, A/D transforming and measuring, then displays it digitally. At the same time, power speech alarm system and speech alarm system, speech alarm system will give alarm, and control the related equipment if it is necessary. It had been approved after using in selector of Pan-steel and it is vanlvable for similar mines.The paper has elaborated the working principle and applied circuit of this system's every unit, and introduced the component part of this system and the operating situation in the laboratory or on the spot.
