NETWORK TIME PROTOCOL SERVER USING STANDARD FREQUENCY SIGNAL AND GLOBAL POSITIONING SYSTEM SIGNAL AND METHDO FOR PROVIDING NETWORK TIME OF THE SAME

摘要

PURPOSE: a kind of ntp server is supplied to using the standard-frequency signal and network and its presentation mode of GPS signal guarantees that the network of precision has the signal of the booming income exchange rate or average value with signal. ;What CONSTITUTION: one GPS signal receiving module (110) received GPS signal includes GPS time information. Standard signal module (120) receives standard-frequency signal. Control module (130) includes the standard-frequency signal for selecting temporal information as network signal to there is highest rate of receiving account to include in standard time information. External standard signal receiving module (140) includes the standard-frequency signal that additional external antenna increases rate of receiving account. A kind of EL modules (150) are by back light unit. Power module (160) provides supply voltage and passes through external impetus. ;The 2013 of copyright KIPO submissions;[Reference numerals] (110) GPS signal receiving module; (120) standard signal module; (130) to lighting module; (140) external standard signal receiving module; (150) EL modules; Power module (160)
