The aim of this article is to independently implement an indispensable front-end platform in a network-based intelligent home healthcare system. We propose to realize an ARM-cored structure embedded with μClinux system to integrate several kinds of medical measuring modules with our platform. Then we demonstrate the platform work cooperatively with all proposed and built -units. This most characteristic point of this platform lies in the implementation of the embedded expert system on the hardware basis. This kind of feature allows those aged and/or long-time patients to get medical diagnosis and advices at home, and, at the same time makes doctors work more effectively and pertinently.
