Description
Summary:碩士 === 國立高雄第一科技大學 === 綠能電路與積體電路設計與應用產業碩士專班 === 103 === This thesis shall propose a set of architecture through power line carrier (PLC) technology so as to realize a set of accurate time transmission and correction system.PLC can take full advantage of existing power lines as well as carrier approaches to transmit signals and its strength lies at that there is no need for reconfiguring the network. Moreover this system can be divided into two parts and the first part can detect portion of the PLC time protocol in addition to converting into currently and more commonly used RS-485 time protocol. The 2nd part shall convert them into the time protocols required by network time protocols (NTP) and PLC time protocols through Global Positioning System (GPS) time information. Within it, NTP can be the computer provided time correction of the to-be-updated computer time in area network. Additionally PLC time protocol can provide the master clock system with a stabilized output. And from the empirical findings we can learn that this system can effectively convert various protocols in addition that it can successfully produce waveform of PLC time protocol as well as in protocol format of NTP system.
