Extraction controller for mining—extraction machines
First Claim
1. A control system for a machine or plant that performs a plurality of functions during an operating cycle, with each function being initiated by a preselected start signal and ceased by a stop signal, the control system comprising:
- a display screen; and
a computer for;
storing a plurality of display screen signals respectively corresponding to the functions, with each display screen signal including a starting limit and a stopping limit so that a duration of the corresponding function is defined between the starting limit and the stopping limit, using the display screen signals to graphically illustrate the duration of the functions on the display screen, and controlling the operating cycle by causing a switching signal to advance in time through the operating cycle and wherein for each display screen signal the controlling includes providing the start signal for the corresponding function when the switching signal coincides with the starting limit and providing the stop signal for the corresponding function when the switching signal coincides with the stopping limit.

Abstract
A machine control system for a machine or plant controls a plurality of functions within an operating cycle. The start signals and stop signals for releasing and ending respectively the function can be preselected with respect to their mutual relative time slot by means of a data processor (computer) with a display screen. To this end, the functions of the machine or plant are listed in parallel lines on the display screen. Each of the functions can be represented in a graphic quantifying the duration of the function by inputting display screen signals with the limits, which correspond to the times of connection (start limit) and disconnection (stop limit) of the respective function. After starting up the operating cycle, the display screen signals are scanned by a switching signal, which advances in time in the direction from the start limit to the stop limit. The connection signal and disconnection signal, respectively are supplied to the machine control system, when the switching signal coincides with a display screen signal. The graphic of each function can be a bar diagram with bars, which are each associated to the functions, and the start and end of which mark the times of connection and disconnection of the respective function on a time axis parallel to the bars.
