PURPOSE:To improve safety by detecting strikers, arranged for indicating their addresses and positions along travelling routes, by means of a detector attached to each travelling body and forming a system capable of comparing a position detecting counter with an address signal, in the captioned device of an automated warehouse. CONSTITUTION:After presetting of a counter circuit 11 by a preset instruction 8, an up-count instruction 10 or a down-count instruction 9 is added according to travelling direction so as to settle count directivity. Then, a travelling body 3 travels, a counter 11 counts the numbers of position indicating strikers 7 detected by a detecter 5 and the result is input into a comparing device 12, and, an address detector 4 detects an address indicating striker 6 when it passes respective address and inputs the address into the comparing device 12. In the comparing device 12, the address output 4 is compared with the counter number 11 and the result 12a is outputted to a travel controlling circuit 15 through a gate 13. An alarm 14 is given if some discordance happens. Thus, the system can be improved in positional accuracy and safety. |
