Roller state monitoring controller and control method

Abstract

The invention relates to a roller state monitoring controller and a control method. The roller state monitoring controller and the control method are used for detecting the running state of a roller.The roller state monitoring controller is characterized by comprising a battery, a charging and discharging module, a power source processing circuit, a voltage / rotating speed sampling circuit, a single chip microcomputer module, and a communication module. An AT89C51 chip is adopted as a core of the single chip microcomputer module. An ADC0809 is adopted to collect and process a microphone, a vibration sensor and a sensor signal and a voltage / rotating speed sampling signal of a temperature sensor. After program calculating, through the communication module, communication with an external industrial control computer is achieved by the IEEE802.11b standard. Data of the rotating speed, vibration, noise and temperature of the roller are output and are updated in real time, and fault of the roller is diagnosed. Self-perception and fault warning of the state of the roller can be achieved. The remaining service life can be predicted as a reference of reasonable formulation of accessories plan. The managing level of a belt type conveying machine is improved, and the roller state monitoring controller is a part of intellectualization of the whole belt type conveying machine.

Description

technical field [0001] The invention relates to a drum state monitoring controller and a control method. Background technique [0002] Belt conveyors are widely used in coal mines, power plants, mines, ports, docks and other occasions. The rollers are used as the transmission and redirection devices of the conveyor belt, and their working performance directly affects the operation performance of the entire conveyor system. In recent years, the level of machinery industry at home and abroad has been greatly improved, and the structure, processing technology, and assembly technology of the drum have undergone tremendous changes. With the rapid development of welding technology, the reliability of welding strength has been improved, and designers are more and more inclined to use welded structures instead of original casting structures when designing drums. In the connection of the detailed structure, the expansion sleeve connection is also chosen to replace the original keywa...
