A ward cloud system comprises an intelligent cloud database and an intelligent electronic vital-sign monitoring device. The intelligent cloud database receives first vital-sign information detected by the intelligent electronic vital-sign monitoring device and second vital-sign information manually input by users through an intelligent transmission unit, integrates received information and undertakes far-end clock synchronization of the intelligent cloud database and intelligent electronic vital-sign monitoring device. The ward cloud system further comprises a far-end calibration unit using the intelligent cloud database to examine and calibrate accuracy of the intelligent electronic vital-sign monitoring device through the intelligent transmission unit from a far end. The present invention adds to an ordinary electronic vital-sign monitoring system the following functions: a manual vital-sign value input function, a far-end automatic clock synchronization function, a far-end calibration function and an intelligent operation function and thus can avoid the serious consequences caused by measurement inaccuracy or clock non-synchronicity.
