Detailed description of the invention
In one embodiment, as shown in Figure 1, provide a kind of ECG monitor. This ECG monitor bagDraw together ecg signal acquiring module 120, electrocardiosignal processing module 140, main control module 160 and wireless telecommunications mouldPiece 180. Wherein ecg signal acquiring module 120 connects electrocardiosignal processing module 140, main control module successively160 and wireless communication module 180.
Concrete, ecg signal acquiring module 120 is for gathering original electrocardiographicdigital signal. Ecg signal acquiring mouldPiece 120 is connected with human body in the course of the work, gathers user's original electrocardiographicdigital signal with this.
Electrocardiosignal processing module 140 and ecg signal acquiring module 120 be connected, receive electrocardiosignal and adoptThe original electrocardiographicdigital signal that collection module 120 collects. And original electrocardiographicdigital signal is processed, comprise originalElectrocardiosignal carries out the processing such as denoising adjustment, makes it to export steady and audible electrocardiosignal.
Main control module 160 is connected with electrocardiosignal processing module 140, receives electrocardiosignal processing module 140The electrocardiosignal after treatment of output. And received electrocardiosignal is carried out to Analysis and judgments, detect institute and connectWhether the electrocardiosignal of receiving belongs to the electrocardiosignal being just usually used in, and detects and judges that whether user's heart rate is abnormal.
Main control module 160 is also connected with wireless communication module 180. Judge user's heart rate when abnormal in analysisWake on wireless communication module 180 carries out work, judges user's heart rate do not go to wake up when normal in analysisWireless communication module 180, makes it keep resting state.
Wireless communication module 180 just enters low-power consumption mode after power-up initializing, is receiving main control module160 send the abnormal electrocardiosignal of representative of consumer hearts rate time just this abnormal electrocardiogram signal is uploaded. As masterControl module 160 communicates with Surveillance center by wireless communication module 180, and the heart rate that sends user is abnormalInformation, or also can notify by wireless communication module 180 supervisor of user preset, can obtain in timeKnow this user's heart rate abnormal conditions.
In the present embodiment, because main control module 160 is judge user's heart rate according to ECG Signal Analysis abnormalTime wake on wireless communication module 180, make it carry out work. Judging user's heart according to ECG Signal AnalysisWhen rate is normal, without wake on wireless communication module 180, make wireless communication module 180 keep resting state always,Upload without receiving electrocardiosignal, thereby can reduce the power consumption of ECG monitor.
In one embodiment, as shown in Figure 2 A, ecg signal acquiring module 120 comprises and being connected with human bodyCrosslinking electrode 122 and the testing circuit 124 that comes off that leads being connected with crosslinking electrode 122.
