To　solve　the　problem　of　exciting　time　reversal　guided　waves,　a　high-voltage　excitation　board,　which　was　suitable　to　excite　piezoelectric　transducer　for　generating　time　reversal　guided　waves,　had　been　designed　and　implemented.　During　the　design　of　excitation　board,　the　interacting　FSM　model　was　used　to　synthesize　the　time　reversal　signal,　amplifier　circuit　was　used　to　drive　high-voltage　output　stage,　and　differential　structure　was　employed　to　realize　the　high-voltage　output　stage　of　exciting　board,　which　ensured　high-voltage　time　reversal　wave　could　be　quickly　generated　in　the　detection　process.　Experiment　results　present　that　the　excitation　board　generated　not　only　ultrasonic　guided　waves　for　the　conventional　detection,　but　also　the　required　high-voltage　time　reversal　waves　for　the　piezoelectric　transducer,　which　make　sure　time　reversal　technology　can　used　for　engineering　applications.
