<p>PROBLEM TO BE SOLVED: To provide a signal processing system capable of continuing signal processing even on the occurrence of abnormality caused by control data and/or an input signal.SOLUTION: A control module 45 operated in a transmission control device 4 determines whether or not there is abnormality in the operation of an engine 53 for monitoring, on the basis of a confirmation signal S2 received at each frame period. The control module 45, on detecting abnormality in the operation of the engine 53, deletes at least a part of data in a transmission frame 20 preserved in a transmission buffer 42 of a working system, to output it to an engine 52 of the working system. The engine 52 continues outputting a normal acoustic signal without receiving the input of the transmission frame 20 causing the abnormality in the operation of the engine 53 for monitoring.</p> |
