STANDARD TIME CORRECTION SYSTEM OF HOMEGATEWAY AND HOMESERVER AND METHOD THEREOF

摘要

A standard time correction system of a home gateway and a home server, and a method thereof are provided to prevent data transmission error caused by internet interruption by resetting the time of the home server or gateway as corrected standard time. A biometric data collector(10) collects the biometric data. A home server(30) stores the data collected by the biometric collector. A home gateway(20) interacts with the home server and the biometric data collector. An external server(40) is connected with the biometric data collector, and receives the data stored in the home server. An external standard time server(50) is connected with the home gateway through the internet, and transmits the standard time to the home gateway. The home gateway is reset unconditionally as the standard time downloaded to the SNTP(Simple Network Time Protocol) of the internet when booting or rebooting. The home server calculates estimation offset of the reset standard time.
