An embodiment of the invention provides a method, a device and a system for measuring pulse signals. The method includes determining the locations of artery surfaces of a to-be-measured object; acquiring a pressure value and applying contact pressures to the locations of the artery surfaces; receiving the pulse signals. The contact pressures correspond to the pressure value. The pulse signals are fed by the artery surfaces and correspond to the contact pressures. According to the technical scheme, the method, the device and the system have the advantages that the locations of the artery surfaces of the to-be-measured object are determined at first, then the different pressures are applied to the locations of the artery surfaces, beating of pulses is converted into impulse waveform signals, basic information of different constitutions can be differentiated and is compared to standard information of the different constitutions, and abnormal fluctuation can be pinched out by multi-frequency sound; the pressures further can be grouped and matched and can be combined with one another to obtain three-dimensional impulse images comprising time axes, pressure axes and location axes, and accordingly the problem of low pulse signal measurement precision of existing force measurement type pulse condition transducers can be solved.
