The pulse diagnosis in traditional Chinese medicine is a method for analyzing and judging the health state of a patient by touching the pulse beats of the radial artery cun, guan and chi parts of the wrist part of the patient by fingers. The pulse feeling of traditional Chinese medicine is mainly carried out by depending on the subjective feeling of traditional Chinese medical doctors. With the continuous progress of science and technology, pulse condition instruments capable of collecting pulse conditions of patients and displaying the curve of pulse pressure changing along with time are developed and applied in actual working life, so that the pulse condition relevant data obtained by transmission of a communication network is simulated in real time by a recurrence device, and the remote judgment of the pulse condition of the patients by traditional Chinese medicine according to the pulse pressure changing condition simulated by the recurrence device is possible. The accuracy of the pulse condition recurrence result is directly related to the performance of the pulse recurrence device.
The chinese patent invention with publication number CN105640513A provides a pulse wave array sensor acquisition system and method, which utilizes an array sensor to acquire pulse information of a wrist part of a patient, so as to achieve the purpose of ensuring that pulse information of cun, guan and chi positions can be completely acquired. The disadvantages are that: based on the pulse wave array type sensor acquisition system, although the pulse information of the cun, guan and chi positions can be completely reproduced by utilizing the corresponding pulse condition simulated by the reproduction device in real time, the specific positions of the cun, guan and chi pulse points can not be accurately found at the reproduction end, and the pulse feeling position still needs to be determined by the traditional Chinese medical practitioner through the experience of the traditional Chinese medical practitioner.

s2, acquiring the average amplitude of the maximum peak of each surface element according to the pressure data of each surface element in the pulse acquisition area;
s3, dividing a surface element with the maximum wave peak amplitude higher than 10% of the average amplitude into guan pulse, calculating the central point of each surface element of the guan pulse according to the coordinate data of each surface element of the guan pulse, wherein the recurrence unit corresponding to the central point is a guan pulse measuring point; the multiple reproduction units are respectively in one-to-one correspondence with the multiple acquisition surface elements;
