This paper mainly explains the use of NTP time server, and makes a brief analysis of the problems encountered in the use of the equipment in the specific project operation and the solutions.

The NTP time service server is a standard time server with the function of correction time. In the market, its standard protocol NTP meets most of the time correction protocols including computers, cameras, monitors, industrial computers and so on, making it occupy a large proportion in the current time synchronization market.

For the use of NTP time server, we first need to check the function of the device parameters, confirm its installation configuration and cable link mode according to its functional parameters, and define the operation steps. Taking the time source as the first function checkpoint, where does the time reference source of its NTP time server come from? It mainly divides into three modes: satellite time, higher level time reference and manual setting time.

For the three time reference sources referred to by the NTP time server, first of all, the manual setup time, generally refers to sending instructions through the serial port of the computer or modifying the time by other means. It can connect the corresponding interface according to the function of the device and operate according to the instructions.Through the higher time reference, it usually means that there are master clock equipment or higher time source equipment in the synchronous time system. The NTP server can acquire the standard time source signals by receiving the timing signals sent by the superior equipment, such as IRIG-B codes, PTP and other different time sources. According to the cable connection mode, the related link configuration connection is achieved to obtain the standard time source signal. 。

This article focuses on the use of the NTP time server for satellite time sources. For satellite time reference standards, there are often satellite antennas installed for this type of time service. The NTP time service server often uses mushroom head antenna during its long term use. Under special circumstances, such as the Research Institute, the use of the other specifications such as sucker type, military green, chili head and other specifications may be used in the army's troops. There is not much explanation here. We mainly talk about the most commonly used mushroom head antenna.

For the installation of mushroom head antenna, we must first determine the antenna length and lead way. Under the standard specifications, the antenna we configure is usually 30 meters, which is in line with the needs of most users. There will usually be more than 50 of the length of the antenna. Meters, 80 meters, 100 meters, such as the length of the specification, which belongs to pre-sale content, for the installation process is often due to receiving satellite signal strength gain, and so on, the cable design, installation bracket and so on, there are subtle differences. Here we mainly need to talk about antenna installation for antenna design. For the problem of mushroom design within 50 meters, we need to install it from indoor to outdoor room, because of the connection between mushroom head and cable, and for more than 50 meters of cable, we can choose freely according to the project.

Before installing the NTP, the cable installation is recommended. After the equipment is debugged, it is suggested that the user first turn on the electricity after receiving the equipment, and at the same time connect the satellite antenna, first check the equipment's star collection, whether the boot state is normal, and then install the cable and configure it.

After describing the time source of the NTP time server, we need to determine its output signal, usually referred to as NTP signal, which is usually a standard RJ45 interface. When configuring it, we only need to log on to NTP when the initial IP address of the server is entered into the system, and modify the IP address and gateway. Before modifying, it is necessary to ensure that the computer equipment that modifies the NTP address is maintained in a network segment with the NTP time server.

Our company's NTP time server is the standard NTP protocol, which meets the time synchronization of NTP protocol devices and sub protocols. It supports all the security protocols, encryption protection, firewall and other functional requirements in the NTP protocol. All the equipment in our factory is set up to meet the fast and portable usage of users. The function of the system has been set. After users get the equipment again, they only need to modify the IP address and gateway, click save and application, and other items do not need to make too many modifications.

When the NTP time server synchronizes the other devices, it only needs to set up the Internet time area or time to set up the area. When the IP address of the NTP time server is obtained, the time synchronization with the NTP time server can be realized. Sometimes we may encounter the problem of the time synchronization error of customers. It may be because Wintime has not been started, the registry has not been modified, and the time zone setting problem has been solved.

The above is a description of some problems in the use of NTP time server. For more pre-sale or after sale problems, we will continue to organize and facilitate users to choose the NTP time server, check and solve problems in the age of use.
