High-precision full-automatic servo control system of roadway support test stand

Abstract

The invention discloses a high-precision full-automatic servo control system of a roadway support test stand. The high-precision full-automatic servo control system is composed of a computer digital control system, a performance detection system, a hydraulic control console, a high-precision hydraulic jack and the like, and is a complete set of mechanic-electric-hydraulic integrated high-technology system equipment. The high-precision full-automatic servo control system takes the high-precision hydraulic jack as an actuating mechanism, uses a signal monitoring system for feedback, adopts a static load servo valve, a flow valve and the hydraulic control console as core components, and realizes actual simulation of a control target under commands of the computer digital control system. The computer digital control system is of a 2-level distributed control structure, and is composed of an upper computer and a lower computer. The high-precision full-automatic servo control system improves the design of the roadway support test stand to be combined with modern electronic and computer science technologies, solves the problems that the equipped measuring and control system of the current roadway support test stand is lagged behind and the performance detection requirement of the current roadway support test stand cannot be satisfied, and is of great significance to the development of the roadway support test stand and the high-precision monitoring and detection of performance of roadway supports.

Description

technical field [0001] The invention relates to an automatic control system, in particular to a high-precision full-automatic servo control system for a roadway support test bench. Background technique [0002] With the development of the coal industry, the depth of coal mining continues to increase, coupled with the continuous improvement of the level of mechanized production and the requirements of high-yield and high-efficiency mines, the roadway support conditions are becoming more and more complex, and higher requirements are put forward for the roadway support technology. . The support technology based on bolts has played an important role in the control of surrounding rock in coal mine roadways, and solved a large number of engineering problems. However, under the condition of deep high stress, a single anchor (cable) support cannot solve this support problem, and the combined support technology of the anchor supporting bracket is an important technical way to solve ...
