PURPOSE: To secure the safety of the whole of a system by automatically separating a trouble generation part at a sub-system unit divided so as to execute the self- diagnosis when a trouble and an abnormality occur at the system which is automatically operated.
CONSTITUTION: For example, the automatic operating system of a vessel is composed of a main control station 14, a navigation control station 15, a stevedoring control station 16, an engine control station 17 and a communication control station 8, respective are coupled by an information transmission line 1 and information is transmitted and received. Respective control stations execute the self-diagnosis at a constant period, always supervises the condition with a main control station 14, and respective control parts detect the CPU fail of the device connected with the self-diagnosis, the data communication abnormality and the communication function abnormality of the control stations themselves. For example, when an engine supervising device 23 connected to the control station 17 fails, an abnormal signal is sent from the control station 17 through the transmission line 1 to the control station 14, inputted to a built-in information input device 2 and the abnormal signal and other data are separated by a signal analyzing device 3. Thereafter, an abnormal signal analyzing device 14 judges the station name, contents and level in which the trouble is generated and when this belongs to the control station 17, it is separated.
