Control system and control method of medium and deep hole trolley

Abstract

The invention is applicable to various drilling equipment for underground engineering. The invention provides a middle deep hole trolley control system and control method thereof. A console is connected with a PLC data acquisition module 1 and a wireless communication module 2, the PLC data acquisition module 1 is connected with a wireless communication module 1, the wireless communication module 1 is connected with a PLC data acquisition module 2, the PLC data acquisition module 2 is connected with a driving module, and the PLC data acquisition module 2 and the driving module are connected with a locomotive end. Firstly, the system acquires the control data of an operation end and the CAN bus data; secondarily, the system converts the control data into a digital signal and then transmits the signal via the wireless transmission module 1, and the wireless transmission of the CAN bus data is realized by the wireless transmission module 2; the system receives the digital signal of the control data and converts the digital signal into a control signal; and at the end, the system transmits the control signal after being subjected to optoelectronic isolation and amplification to the locomotive end for response control. The middle deep hole trolley control system and the control method thereof are applicable to downhole middle deep hole drilling machines.

Description

technical field [0001] The invention relates to drilling equipment applied to various underground projects, in particular to an underground medium-deep hole drilling machine. Background technique [0002] Lanjian Mine, a mining company, has entered the stage of underground iron ore mining. An important part of underground iron ore mining is to use medium and deep hole drilling rigs for drilling and blasting. The medium and deep hole rock drilling jumbo is mainly composed of two parts: one is the operation table, and the other is the trolley. The operator drills holes by operating the trolley at a place several meters away from the trolley. Currently, two wired cables containing dozens of control signal lines are used to realize signal transmission between the console and the trolley. Due to the watery and rough ground of the underground mine, the two cables often contact and rub against the ground, which is easy to be damaged, which affects the transmission of signals, resu...

Problems solved by technology

But in terms of safety accidents, there are still certain defects: (1) The locomotive often moves during work, and the transmission cable will be dragged on the ground, which not only causes inconvenient movement, but also is prone to wear and tear, such as drilling and falling rocks and moving dragging The damage of the cable will affect the control signal transmission and even stop the equipment; (2) In the existing SIMBA H1354 operation, the operator and the console are directly exposed to the underground environment, and the underground operating environment is harsh, humid, noisy, falling rocks and other unfavorable factors All directly affect the health and safety of operators and equipment, and it is not conducive to operators to concentrate on completing operations
