Abstract:
Objective:To solve the problem which the time of various information systems were not synchronization and there were time error in them through adopted synchronization time server of dual-mode satellite that were global position system (GPS) and Beidou navigation satellite system (GPS/BDS).Methods: By introducing the synchronization time server of dual-mode satellite (GPS/BDS), the time could be synchronization in real-time with satellite time of GPS/BDS through antenna. And then, using it to ensure the time of server could accurately realize synchronization with international coordination time. All of servers or workstations that need achieve time synchronization chose the IP address of internet time synchronization server as special IP address of time server in the interior framework of hospital so as to achieve synchronization in operation on appropriate frequency. Through the terminal program of time server to append the IP address of digital clock so as to realize the time of digital clock getting synchronization with time server.Results: The synchronization time server of dual-mode satellite (GPS/BDS) could ensure the accuracy of time in operating system of various servers and workstations, and ensure the accuracy of acquisition time of various application system. Therefore, it ensured the accuracy of recording time in data base of various information system of hospital, and resolved the problem which the time of various information systems were not synchronization and there were time error.Conclusion: The server of local area network(LAN), workstation and digital clock can achieve synchronization with universal time coordinated(UTC) by using synchronization time server of dual-mode satellite (GPS/BDS), and it can obtain good effect.
