The invention discloses a three-part five-dimensional digital pulse condition sensor, belonging to the field of medical electronics. The technical scheme adopted by the invention is as follows: three sensing heads respectively collect the pulse condition information of three transverse parts of feet, close and inch as well as 36 longitudinal paths, and transmit the pulse condition information to a signal selecting and amplifying module; the signal selecting and amplifying module selects, filters, regulates and amplifies the pulse condition information transmitted by the sensing heads, amplifies pulse-taking pressure information transmitted by a hydraulic drive module and then transmits the processed information to an A/D switching control module; the A/D switching control module carries out digital storage of simulated pulse condition information and the simulated pulse-taking pressure information of each part, combines the simulated pulse condition information and the simulated pulse-taking pressure information with the pulse condition information and then transmits to a data transmission module; the data transmission module sends the transmitted pulse data to an upper computer through a serial port; and a master control module interprets the commands of the upper computer, coordinates other modules, and realizes finger flexibility pulse-taking through simulation by utilizing the hydraulic drive module. The invention can effectively solve the defects of the existing pulse condition sensor, and realizes synchronous collection, digitalization and transmission of three parts of feet, close and inch as well as five-dimensional pulse condition information of transverse pulse conditions, longitudinal pulse conditions, pulse condition strength, pulse-taking pressure, pulse condition time and the like.
