<p>The units necessary for demand registering and control are positioned sequentially and the first sequence stage (I) is formed by a central disposition unit (DZ), and by connected station units (BE1-BEn). Due to a registering of demand in the station units, the central unit actuates the necessary action at the sequential stage (II). This stage consists of several central operation units (Z1, etc.) Each of these tests the instructions from the central unit, or the station units, with special regard for safety factors, and then feeds them to a third stage (III). This stage consists of vehicles, etc. (BN1-n) which constantly exchange information with the associated operation units, and carry out commands.</p> |
