PROBLEM TO BE SOLVED: To more precisely monitor and diagnose information and signals such as a history or the like inputted and outputted to each part of a radio remote control system. SOLUTION: In a diagnostic device that consists of a monitoring device 52 in a radio remote control system for remote controlling a controlled equipment 23 and an analysis device 54, the monitoring device 52 extracts operation information 24, which is transmitted from an operation terminal 6 to a radio receiver 20 at every prescribed cycle T0 , an operation signal 26 transmitted to an operating circuit 22 from a control device 21 and supervision information including a working signal 27 of the operating circuit 22 and writes them into a memory card 53 together with time information t. Also an analysis device 53 diagnoses the number of times of operation which is performed at the operation terminal 6 of the radio remote control system, an operation history of each part including the number of times of working in the operating circuit 22 and whether there is an abnormality in each part. |
