Problems solved by technology
[0006] In the above method, the disadvantages are: it is necessary to install a large number of electronic components such as sensors and cameras, and in the presence of narrow, dark, noisy, electromagnetic interference and wireless signals in the underground, and the number of hydraulic supports is relatively large, the When the "three machines" work on the working face, some structural motion information cannot be collected by sensors, and it is difficult and expensive to use electronic components to obtain the angle, distance, and position of the hydraulic support of the pushing mechanism

The invention discloses a method for obtaining the position of a group hydraulic support based on an expert system. The method comprises the steps that the expert system based on motion parameters ofa hydraulic support and scraper conveyor floating connection mechanism, the relative position of the hydraulic support and a scraper conveyor and the position of the hydraulic support on a coal seam when the hydraulic supports pushes the scraper conveyor on the coal seam is established; the extension length of a pushing oil cylinder and the inclination angle of a hydraulic support base on the coalseam are obtained underground a coal mine, and after a knowledge base is entered for inquiring and analyzing, reasoning is performed through a reasoning machine to obtain the corresponding hydraulicsupport position of the hydraulic support in a virtual environment; and the hydraulic support position obtained after reasoning is subjected to data processing, then the hydraulic support position obtained after reasoning corresponds to the real position underground the coal mine, and finally the obtained position of the hydraulic support is output to a user interface. Through the method, the situation that a large quantity of equipment is used for detecting the position and pose of the hydraulic support is avoided, the cost is saved, and operation is easy and convenient.
Description
technical field [0001] The invention relates to the technical field of mine simulation, in particular to a method for obtaining the position of a group hydraulic support based on an expert system. Background technique [0002] In order to reduce the coal mine accident rate, improve mining efficiency and mining competitiveness, precise mining and transparent mining have become the goals pursued by the current coal mining industry. Hydraulic support is one of the important equipments in fully mechanized mining face. It mainly supports and manages the roof through the supporting force generated by the liquid pressure and realizes automatic transfer. However, due to the continuous advancement of the fully mechanized mining face and the large number of hydraulic supports, the position of the hydraulic supports changes dynamically. Obtaining the position of the hydraulic supports in real time is one of the important foundations for realizing the intelligent and unmanned fully mech...
