Problems solved by technology

[0003] However, the electro-hydraulic control system of the hydraulic support is still semi-automatic and requires manual intervention, which does not meet the requirements of intelligent control.
In particular, the cooperation ability among the various devices in the electro-hydraulic control system of the hydraulic support is not very strong, and the coordinated operation of the fully mechanized mining work in the well cannot be well guaranteed.

Embodiment 1

[0031] Such as image 3 As shown, the control agent is the core part of the control layer agent, and the main control unit of the control agent is the microprocessor I in the rack controller. In the process of controlling the Agent for intelligent control, the expert system will guide the Control Agent to perform reasonable actions to prevent misoperation or over-action and ensure equipment safety. Its control signals include: 1) lifting column, lowering column, the support is raised and lowered through the expansion and contraction of the column oil cylinder; Lift the base so that the bracket can move forward smoothly; 4) Stretch and retract balance, adjust the attitude of the bracket, so that the top plate of the bracket can adjust the load distribution according to the working conditions; 5) Extend and retract one-level mutual help. Adjust the support posture of the bracket according to the working conditions; 6) extend and retract two-level mutual help. Adjust the suppor...

Abstract

The invention discloses an artificial intelligent type hydraulic support electric-hydraulic control system which comprises a hardware layer, a system layer, a specialist system and a data base. The system conducts communication through a communication bus and adopts a full duplex signal. The system layer comprises management layer Agents and control layer Agents, and each hydraulic support corresponds to a control layer Agent. The specialist system is connected with a communication bus signal, and the data base stores sensing parameters of three machines and is in signal connection with the communication bus. The artificial intelligent type hydraulic support electric-hydraulic control system has the advantages that the system layer calls the current sensing parameters of the three machines saved by the data base, ultra long instruction words are formed finally by calling the sensing parameters of the three machines through the specialist system, the sensing parameters are transmitted to each hydraulic support controller through the communication bus, the control layer Agents make an automatic movement decision on data information, the management layer Agents coordinate movements of the control layer Agents, and intellectualization of the hydraulic support electric-hydraulic control system of a whole fully mechanized coal mining face is achieved.

Description

technical field [0001] The invention relates to a control system, in particular to an artificial intelligence type hydraulic support electro-hydraulic control system. Background technique [0002] In order to meet the needs of fully mechanized mining automation to the greatest extent, the electro-hydraulic control technology of hydraulic support has been widely used. At present, the electro-hydraulic control system of the hydraulic support can realize actions such as automatic moving of the support, automatic pushing of the scraper, and automatic spraying. [0003] However, the electro-hydraulic control system of the hydraulic support is still semi-automatic and requires manual intervention, which does not meet the requirements of intelligent control. In particular, the cooperation ability among various devices in the electro-hydraulic control system of the hydraulic support is not very strong, and the coordinated operation of the fully mechanized mining work in the well ca...
