<p>PURPOSE:To simplify the program structure of a central control unit by allocating carrier work by means of permitting respective individual control means to select appropriate carrier request data among carrier request data which are set in a common data area. CONSTITUTION:When an article carrier instruction is given, the central control unit 7 generates carrier request data and accumulates them in the common data area in RAM 13. When a track is standing by, a controller 10 receives carrier request data accumulated in the common data area from the central control unit 7, calculates work completion scheduled time limit based on the position of the controlled truck, the content of carrier work and carrier request time limit and judges whether it is to be processed or not. When there is no carrier request data judged to be processed, a system continuously stands by and waits for the transmission of new carrier request data. When it is judged to be processed, effect that carrier request data is selected is transmitted to the central control unit 7.</p> |
