This　paper　presents　a　method　of　pulse　waveform　automatic　judgment　and　detection　automatic　control.　Pulse　waveform　detecting　automatically　started　by　the　judgment　of　sampling　value　change　caused　by　transducer　clamping　on　finger.　The　effective　pulse　waveform　was　obtained　after　analog　and　digital　filtering　of　pulse　wave　signal　and　removal　of　baseline　drift.　Single　pulse　waveform　was　obtained　by　the　extraction　of　starting　points　utilizing　the　differential　threshold　method.　Single　pulse　waveform　was　automatically　identified　based　on　classification　of　single　pulse　wave　pulse　waveforms.　Pulse　waveform　detecting　automatically　stopped　by　the　judgment　of　the　absolute　errors　of　continuous　three-screen　average　pulse　waveform　characteristic　values　less　than　0.005.　Results　of　actual　measurement　experiments　show　that　pulse　waveform　can　be　effectively　identified　and　detection　of　pulse　waveform　can　be　automatically　controlled.　This　method　has　a　wide　range　of　applications　in　pulse　wave　detection.
