PROBLEM TO BE SOLVED: To provide an automatically driven equipment system capable of securing safety of an entering person in an entry protection fence, and allowing the person to go through the entry protection fence through entry doors.SOLUTION: A transport vehicle system 1 includes monitoring boxes 22A, 22B in correspondence with a pair of entry doors 33A, 33B outside an entry protection fence 31. The monitoring boxes 22A, 22B respectively include the same number of key insertion parts 24A1-24A8, 24B1-24B8 so as to make pairs, for outputting signals depending on insertion/non-insertion of keys. A monitoring key 25 combined with an opening/closing key 39A for opening/closing the entry doors 33A, 33B is inserted into one of a predetermined pair of key insertion parts among the key insertion parts 24A1-24B8. A key management circuit 40 electrically connects key insertion parts 24A1-24B8 making pairs, and detects whether the corresponding monitoring key 25 is inserted into one of the pair of key insertion parts. An entering person grasp device 13 restricts the motion of a transport vehicle 3 when the monitoring key 25 is not inserted. |
