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

Abstract

An intelligent open-pit coal mine shearer system involves an inertial navigation system / odometer combined navigation method applied to an intelligent open-pit coal mine shearer system. The inertial navigation system in the system is installed on the top of the continuous miner; the mileage The meter is installed on the walking part of the continuous miner; the motion direction control mechanism of the continuous miner is installed on the continuous miner; the inertial navigation system, the odometer and the motion direction control mechanism of the continuous miner are all connected to the host computer through an optical cable; the inertial navigation system in the system / Odometer combined system is installed on the coal shearer. This high-precision navigation, positioning and orientation method does not require any external information and is not subject to external interference; in order to deal with the complex electromagnetic environment in the mine and the corrosion of coal dust on the signal transmission line, In this system, the optical fiber transmission technology is used to transmit the information collected by the navigation system to the host computer. The host computer processes the collected information and uses the PID control algorithm to control the shearer to make it work in a predetermined 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...
