Title: Apparatus for determining the source location of acoustic emissions
IPC: G01S5/18
Filed: 1976-03-08
Abstract: 1497991 Acoustic measuring apparatus WESTINGHOUSE ELECTRIC CORP 8 March 1976 [13 March 1975] 09159/76 Heading G1G An apparatus for determining the location of a source of acoustic emissions generated within or on an acoustically conductive medium which is segregated into a plurality of monitoring zones comprises a plurality of acoustic transducers, each zone having at least three transducers at corresponding monitoring locations, and the monitoring locations being arranged so that adjacent ones of the monitoring zones share at least one transducer, means for identifying the zone first encountering an acoustic reception on all of its corresponding transducers, and means for processing the electrical outputs of the transducers to provide the difference in reception time of the acoustic emission at the corresponding transducers for the determination of the location of the source of the acoustic emission. As shown in Fig. I A the location of faults in the pressure walls of a reactor vessel 10 is detected by segregating the wall into ten zones by transducers 12-36. The output of each transducer is applied to a circuit as shown in Fig. 4. A signal from a transducer, after conditioning in circuits 64, 66 and 68, is applied to set a flip-flop 58 via an inverter 70 and a differentiator 72. Once set, the flip-flop 58 applies a signal QN to output terminal 84, a signal via differentiator 76 to reset a counter 60 and a signal to a NAND gate 74 which then allows clock signals applied to terminal 62 to be applied to the counter 60. When all four flip-flops 58 of transducers of a particular zone are set, a hold signal is applied to reset each of the flip-flops thereby preventing the counters 60 from increasing their count. A computer (not shown) then reads the contents of the four counters to determine the differences in times of arrival of the acoustic emissions at the four transducer locations and thus the x, y co-ordinates of the source of acoustic emissions. Interface circuitry between the transducers and the computer is described with reference to Figs. 5-7 (not shown).
