The invention discloses an intelligent system for TCM comprehensive diagnosis and treatment via a cloud server. The cloud expert system for TCM diagnosis comprises a near-end data collection unit, a central control unit and a cloud TCM expert diagnosis and treatment database server. A user logs in a cloud health account registered in a system via a personal cloud health USBkey, then enters a personal health archive; the near-end data collection unit collects patient face, coated tongue, tongue base and radial artery pulse signal data and then transmits the data to the central control unit; the central control unit transmits a digital signal being amplified, compensated, filtered and A/D converted to the cloud server; and a comparison is made between the data and expert data in the cloud server, and a diagnosis result can be achieved. Data required for TCM diagnosis is comprehensively collected; and a great amount of cloud data is effectively utilized for diagnosis, so cloud health management and national TCM inheritance can be promoted.
