Intelligent control system and control method for scraper conveyer

Abstract

The invention provides an intelligent control system and a control method for a scraper conveyer, which belong to the intelligent control systems for coal mine exploitation. The intelligent control system for the scraper conveyer comprises a laser scanning ranging device, a ray ranging transmitter, an ultrasonic level sensor, a current transducer, a master controller, a variable frequency and speed regulation controller, a coal crushing controller, a conveyor gesture controller and a conveyor chain stretching controller, wherein the laser scanning ranging device, the ray ranging transmitter, the ultrasonic level sensor and the current transducer transmit detection signals to the master controller in a wireless communication manner, and the master controller sends control instructions to the variable frequency and speed regulation controller, the coal crushing controller, the conveyor gesture controller and the conveyor chain stretching controller in the wireless communication manner. The running state of the scraper conveyer is mastered at any time and corresponding devices are controlled timely through monitoring of the laser scanning ranging device, the ray ranging transmitter, the ultrasonic level sensor and the current transducer, so that the scraper conveyer can be operated in an optimum running state.

Description

technical field [0001] The invention relates to an intelligent control system and control method for coal mining, in particular to an intelligent control system and control method for a scraper conveyor used in conjunction with a roller shearer. Background technique [0002] The scraper conveyor is one of the important equipment in coal mining. The current technology is mainly mechanized, and the control system is centralized sequential control, which has poor adaptability. The scraper conveyor adopts chain transmission. When the chain is slack during long-term operation, the current chain tightening technology is to use a hydraulic cylinder to tension the chain, then use a cylindrical pin to mechanically position it, and then withdraw the hydraulic pressure after positioning. This technical solution makes the chain overall larger In the state of tension, it is easy to cause greater wear. When the chain link is extended, the tension decreases, and it is easy to cause the cha...
