Remote control system for coal mining machine

Abstract

The invention relates to a remote control system for a coal mining machine. The system comprises the coal mining machine. The working state of the coal mining machine is transmitted to an onboard control system and an onboard image acquiring system. Upon receiving the working stateinformation, the onboard control system transmits the working state information to a signal converter through a ZigBee wireless communication and transmission module. The onboard image acquiring system transmits the working state image information to the signal converter through a WiFi wireless communication and transmission module. The signal converter converts received signals into electric signals and transmits the electric signals to both a ground control center and a coal mining machine simulator through wired transmission media. The ground control center conducts information interaction with a cloud server through an Internet networking module. The cloud server conducts information interaction with a remote control terminal through the Internet networking module. The ground control center transmits control signals from the remote control terminal to the signal converter through wired transmission media and the signals are converted into wireless signals. The wireless signals are then transmitted to the coal mining machine to control the working of the coal mining machine through the ZigBee wireless communication and transmission module and the onboard control system.

Description

technical field [0001] The invention relates to a coal shearer control system, in particular to a coal shearer remote control system based on the Internet of Things. Background technique [0002] At present, the shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. The current operation of the shearer is mainly through manual operation, that is, through the control panel installed on the shearer body, or the staff uses a wireless network to realize the remote control of the shearer underground. The underground working environment is harsh and there are many safety hazards, such as major disasters such as dust, gas outbursts, gas and coal dust explosions, roof accidents, etc., which pose a great threat to the lives, health and safety of workers. Realizing the remote control of the coal mi...

AI Technical Summary

Problems solved by technology

Many countries, such as coal companies in the United States and Australia, are at the forefront in this regard. China's technology in this area is relatively backward. Most of the existing remote control is underground, and many long-distance remote controls have only been realized. A monitoring of the working environment and status of the shearer without realizing its control

In addition, although some coal mines in China have realized remote monitoring of underground coal mining machines, most of them have defects such as complex structure, high cost, low reliability and humanization, and it is still impossible to realize remote monitoring through personal handheld mobile monitoring terminals, etc. The equipment remotely monitors the working status of the shearer anytime, anywhere
