Intelligent open-pit coal mine coal continuous miner system

Abstract

The invention relates to an intelligent open-pit coal mine coal mining machine system, in particular to an inertial navigation system / odometer integrated navigation mode applied to the intelligent open-pit coal mine coal mining machine system. The inertial navigation system of the intelligent open-pit coal mine coal mining machine system is installed at the top of a continuous miner, the odometeris installed on a walking part of the continuous miner, and a continuous miner movement direction control mechanism is installed on the continuous miner. The inertial navigation system, the odometer and the continuous miner movement direction control mechanism are all connected to an upper computer through optical cables. The inertial navigation / odometer integrated system of the intelligent open-pit coal mine coal mining machine system is installed on a coal mining machine, the high-precision navigation positioning and orientation method does not need any external information and is free fromexternal interference. In order to cope with the complex electromagnetic environment in a mine channel and the corrosive effect of pulverized coal on a signal transmission line, the optical fiber transmission technology is used in the system to transmit the information collected by the navigation system to the upper computer, and the upper computer processes the collected information and uses a PID control algorithm to control the coal mining machine to enable the coal mining machine to work in the given direction.

Description

technical field [0001] The invention relates to an intelligent open-pit coal mine continuous miner system, in particular to an inertial navigation system / odometer combined navigation mode and a PID control algorithm applied to the intelligent open-pit mine continuous miner system. Background technique [0002] With the development and implementation of the national energy strategy in recent years, yes coal mining has gradually developed from high-yield to green mining, safe development and efficient mining. The automation and intelligence of fully mechanized coal mining face is a key step to realize unmanned, safe and efficient mining in the mine, and it is also an important part of developing "digital mines" and improving the informatization and automation level of mine electromechanical equipment. One of the most effective solutions to realize the intelligence of coal mining is to realize the automation of coal mine production equipment, so as to realize unmanned or less-m...

Problems solved by technology

[0003] The working information of the continuous miner includes the position and attitude of the continuous miner. The current popular GPS navigation and positioning cannot work normally in coal mines, and cannot detect the real-time working attitude of the continuous miner.

This leads to the impossibility of automation of the continuous miner system

In the process of information transmission, the complex electromagnetic interference and harsh environment in the coal mine will cause serious interference to the general bus transmission
