PURPOSE:To simplify circuit constitution by expressing many stations by combinations of columns and rows, by specifying each station by specifying a column and a row, and by specifying the operation of an unmanned guided vehicle at the stations. CONSTITUTION:A column specifying circuit 5 specifies the running route (guidance line 4) of a guided vehicle. Its column-specification signal is sent to detection signal selecting circutis 7A, 7B and 7C, and output signal distributing circuits 9A, 9B and 9C. The detection selecting circuits 7A - 7C correspond to respective rows, and input state detection signals from station state detectors of stations S belonging to the row, respectively. The selecting circuits 7A - 7C fetch and decode signals, from the stations belonging to the rows specified by a column specifying circuit 5 among the state detection signals from the stations S belonging to the rows, and send the results to signal control circuits 8A, 8B and 8C, respectively. |
