Multi-channel pulse signal detecting method and device capable of automatically regulating pressure

The invention relates to a multi-channel pulse signal detecting method and device capable of automatically regulating pressure. The method comprises the following steps: 1) sticking wrist bands with a cun-pulse sensor, a guan-pulse sensor and a chi-pulse sensor on a wrist respectively; 2) collecting pulse signals under collecting pressures of light, medium and heavy, and transmitting the signals to a signal regulating circuit; 3) converting the pulse signals which are processed by the signal regulating circuit into digital signals, and storing the digital signals in a singlechip; and 4) transmitting the digital signals to a computer by the singlechip, displaying a real-time pulse signal curve by the computer, and performing pulse cycle identification and pulse characteristic extraction onthe pulse signal curve to complete the pulse signal detection. The device comprises the wrist bands, the cun-pulse sensor, the guan-pulse sensor, the chi-pulse sensor, a pressure sensor, the signal regulating circuit, an analog/digital (A/D) converter, the singlechip, the computer and a pressurizing module. Compared with the prior art, the device has the advantages of low power consumption, high pressure control accuracy, multi-pulse position integral representation and the like.
