Abstract:
PCT No. PCT/GB90/00076 Sec. 371 Date Mar. 11, 1991 Sec. 102(e) Date Mar. 11, 1991 PCT Filed Jan. 18, 1990 PCT Pub. No. WO90/09644 PCT Pub. Date Aug. 23, 1990.The operation of an engine or other assembly is monitored by detecting the sound it makes and deriving from this, in conjunction with its speed, temperature and control settings, a multi-dimension condition vector. The vector changes during operation of the engine and is supplied to a processor which continuously builds a model of the engine at different stages of operation such as by a sequence-learning neural net or by hidden markov model when an atypical condition vector is received, the processor generates an alert signal to a display.
