PROBLEM TO BE SOLVED: To provide a diagnostic system for induction coupling radio equipment with which the abnormality occurrence of a gap between an antenna and a guide line at the induction coupling radio equipment can be speedily dealt with and recovered in a short time and prevention maintenance such as repair based on periodical check or the arrangement of track of a mobile machine can be efficiently performed. SOLUTION: When transmitting information through the induction coupling radio equipment between a base station and a mobile machine 11 moving on a prescribed travel line 12, a reception level of the induction coupling radio equipment and the traveling position of the mobile machine 11 are detected by a position detector 26 and based on this detected information, the gap between antennas 16 and 23 of the induction coupling radio equipment and a guide line 13 is controlled in on-line state corresponding to the traveling position of the mobile machine 11. |
