The invention provides a signal detection device, which comprises a slope detection circuit, a window comparison circuit and a latch circuit, wherein the first input end of the slope detection circuitis used for inputting first voltage; the second input end of the slope detection circuit is used for inputting reference voltage; the slope detection circuit is used for outputting second voltage according to the reference voltage and the first voltage; the first input end of the window comparison circuit is electrically connected with the output end of the slope detection circuit; the second input end of the window comparison circuit is used for inputting upper limit voltage; the third input end of the window comparison circuit is used for inputting lower limit voltage; the window comparisoncircuit is used for respectively comparing the second voltage with the upper limit voltage and the lower limit voltage and judging whether to output the third voltage or not; the first input end of the latch circuit is electrically connected with the output end of the window comparison circuit; and the latch circuit is used for performing data processing on the third voltage and outputting the third voltage to a single chip microcomputer. The design complexity is reduced; simplicity and convenience are realized during the detection; and the cost can also be reduced.
Description
technical field [0001] The present application relates to the technical field of signal detection, in particular to a signal detection device. Background technique [0002] The main function of the pacemaker is to excite itself (QRS wave group reflects the change of left and right ventricular depolarization potential and time, the first downward wave is Q wave, the upward wave is R wave, and then the downward wave Wave is S wave) before the pulse, a small shock voltage signal (ie pace pulse signal) is applied to the heart to assist the blood flow in the body. This signal can take many forms and can be broken down into specific amplitudes and signal widths. [0003] The pace pulse signal height and width of the cardiac pacemaker signal can be varied arbitrarily within the amplitude range of 2mV to over 500mV, and the width range of 0.1ms to 500ms. At the same time, it may have similar signal characteristics to ECG (electrocardiogram, electrocardiogram) pulse signal. The sh...
