High precision GPS clock benchmark has become one of the basic guarantee platforms in communication, power, radio and television, security monitoring, industrial control and other fields. The satellite navigation and positioning system can provide high precision, all-weather, all-weather navigation, location and time service, excellent timing performance, high precision, low cost, safety and reliability, all-weather and wide coverage.

GPS clock source is a newly developed time service product based on the development of GPS satellite timing module. It can output the time information format that accords with the specification according to the user's needs, so as to complete the synchronous time service.

The GPS clock is a high-tech product aiming at the calibration of computers, medical instruments and control devices in the automation system. The GPS clock acquires time information from the satellite. The GPS clock internally processes and converts these time information into high technology, and transmits the equipment that needs time information through the hardware interface (network port) to the LAN of the automation system, so that the time synchronization of the entire network system can be achieved.

In the traditional medical industry, there are a series of problems in the synchronous clock. We have made many improvements in the long-term practice of the synchronous clock system in the medical industry. At present, we have made a highly systematic integration design for the synchronous clock system in medical industry, omitting the redundant design in the middle, and concluding the whole system into a hospital master clock system, meeting the needs of modern hospital clock synchronization system.

The medical industry clock system composed of the mother clock system and the mother clock and sub clock integrates the satellite receiver, the master clock, the NTP clock server and the time code distributor to a high precision clock server. The SYN2151 type clock server is fully equipped with the clock server of the above functions.At the same time, the sub clock and other management system software can be simplified to achieve one time setting and maintenance free high efficiency, so as to form a hospital bell device with high cost performance.

In the entire medical synchronous clock system, the earliest hospital clock system is integrated into a satellite antenna, and the master clock, switch and sub clock are directly connected to a set of hospital time synchronization system devices, removing the other redundant devices in the middle, while on the other hand, it also improves the error caused by the transmission between devices, which is easy to install and greatly reduces the cost of input.

In the medical clock system, the standard NTP network time protocol is used as the transmission protocol to realize the time synchronization of computer equipment in the network. The function of NTP is to synchronize the computer clock in the LAN to the standard time, and its accuracy can reach 0.1ms within the LAN. The accuracy in most parts of the Internet can reach 1-50ms.

Therefore, it is of great significance to provide a reliable, economic and effective master clock system in the important areas of the hospital to provide a unified and standard hospital time for the digital management of hospitals and the unified coordination of all departments in the hospital.
