  • Longwall support control for controlling the movements of longwall support units in the longwall of a mine
    Patent number: 7455367
    Abstract: A longwall support control for controlling the movements of longwall support units in the longwall of a mine that includes a central control system and a plurality of control units, of which a separate control unit (mining shield control device) is locally and operationally associated to each longwall support unit. The mining shield control devices connect to the central control system and to one another via two bus lines, through which each of the mining shield control devices can be called up for inputting a control command from the central control system or an adjacent mining shield control device. The identical second bus line (parallel bus) permits retransmitting to the adjacent mining shield control device, incoming signals that do not store a code word assigned to the respectively addressed mining shield control device.
    Type: Grant

  • Timbering and walling control for controlling the movements of timbering and walling units in the coal face of a mine
    Patent number: 7416369
    Abstract: A longwall support control for controlling the movements of longwall support units in the longwall of a mine that includes a central control system and a plurality of control units, of which a separate control unit (mining shield control device) is locally and operationally associated to each longwall support unit. Each mining shield control device comprises a switching element, which permits separating the bus line or lines in the mining shield control device. The mining control devices may also include signal amplifiers. An identical second bus line (parallel bus) permits retransmitting to the adjacent mining shield control device, incoming signals that do not store a code word assigned to the respectively addressed mining shield control device.
