Embodiment Construction

[0013] figure 1 The reference number 1 in the underground mining designates a programmable electronic control device for many different control operations in underground mining. Control work can involve face excavation with electro-hydraulic support of the excavation slab, conveyors, roller loaders, skids and section boring machines or monorail cranes etc. A preferred application is the support of underground excavations with support excavation plates distributed over the length of the working face. These excavation panels are respectively controlled via a data bus, and monitor the sensors arranged at the corresponding support excavation panels, and operate actuators, such as electro-hydraulic valves, to make the lifting punches (Hubstempel) at the excavation supports inwards or Outward movement, or by inward or outward movement of the return roller (Rückzylinder), the driving support is moved in the mining direction. Electrohydraulic tunneling supports are known and therefo...

Abstract

A controller is disclosed for control operations in underground mining, especially for controllers to control support shields. The controller utilizes a central unit with a microprocessor and assigned, programmable memory devices for the storage and processing of software as well as a connector unit with connectors or circuits for communication between the controller and other controllers and / or actuators, sensors or the like, that are to be controlled with the controller. Both the central unit and the connector unit utilize a modular design. A collection of modules with different performances and / or functionalities are provided for both the central unit and the connector unit to form the hardware of a controller. The modules can be combined with one another and coupled together according to a modular concept.

Description

field of invention [0001] The invention relates to a control device for implementing control operations in underground mining, with modular hardware comprising a central unit with a microprocessor and corresponding programmable memory means for storing and processing software , and a connection assembly for communicating the control device with other control devices and / or actuators to be controlled, sensors or the like. Background technique [0002] In underground mining, it is always desirable to use as general and uniform a control device as possible for control in different fields of application in order to save costs for hardware development, production, acquisition, and spare parts inventory. The main field of application for the corresponding control is the underground electrohydraulic support (Schildausbau) of coal excavation systems with plows or shearers, since a very large number of actuators or sensors must be connected to the respective coal excavation systems ...
