Abstract

PURPOSE:To find a fault in a short time in a fault diagnosis of a sonar device, by automatically collecting and judging data from respective equipments by a bus-line system by using a computer. CONSTITUTION:Testing device 20, while brought under the control of fault diagnosing device 10 with a computer program via but line 40, sends measurement data back to diagnosing device 10. Computer 50 sends digital signal 46 to receiver and latch circuit 56 via driver circuit 52. Next, set pulse 44 is sent to place test setting circuit 1 in a test state. When the data of circuit 2 to be tested is a digital signal, it is sent to driver circuit 57 via measuring circuit 3 and for data collection, computer 50 obtains the data by receiving them from driver circuit 57 by receiver circuit 53. This operation is repeated for N channels. This data is compares with a rated value in the computer for a diagnosis. This constitution makes it possible to find a fault in a short time.
