The Reappearance Research Of Chinese Medicine Pulse

Abundant information including the status of health of the human body is loaded by pulse image. Pulse diagnosis takes important part in four kinds of disease diagnosis in Chinese Medicine. Pulse diagnosis is the important part of diagnostics in Chinese Medicine .The reappearance of pulse image may be used to demarcate the instrument of pulse diagnosis and the sensor of pulse diagnosis. At the same time, an objective standard is established for pulse diagnosis. The dynamic reappearance of pulse image is beneficial for saving the skills and the viewpoints of the expert in Chinese Medicine, the practice experience and the study production may be discussed by the same words. Furthermore, it provides an effective method for modern teaching about the Chinese Medicine pulse, which is convenient for the beginner when they learn to feel the pulse.The technology of virtual instrument combines the technology of computer, digital signal processing, standard bus and software engineering method. It represents the development direction of the measuring instrument and auto-testing system in the future. Although Medical instrument has its special places, it has a system of measurement too. As long as supplying the parts of front end, the virtual medical instrument can be constituted.At the base of studying the pulse characteristic, the paper has completed the reappearance of pulse from the viewpoint of the electronic signal, and has achieved the scale of the pulse sensor and the system of reappearance. The system is made up of the software based on LabVIEW, DA card, and power drive circuit and bidirectional sensor. The characteristic parameters of pulse can be obtained using the application software made in the paper, which is fully satisfied with the pulse reappearance. DA card based on microcontroller is an intelligent circuit, and it receives pulse data from computer, saves it, forms period signal and sends it to power drive circuit. It is connected by power drive circuit and the magnetic sensor, and the pulse current signal is changed the pulse force by the bidirectional characteristic of the magnetic sensor, thus is completed the pulse signal dynamic reappearance.The system fully utilizing the resources of computer makes the design of medicine instrument simply, flexible, modular, easy to mend, good repeatable and economical etc. furthermore, its function is enhanced. For example, the capability of saving, government and signal analysis has been advanced. At the same time, user interface is more beautiful and friendly, and the operation is very simple.It has several innovation points in the paper. It has realized the dynamic reappearance of pulse image by use of virtual instrument technique, intelligent instrument technique, information processing and sensor technique, etc. the reappearance don't simulate the pulse information from the form truth, while is completed from the view of electronics.
