Abstract
The invention relates to a novel method for synchronizing Intranet time and Internet time. The method comprises the following steps of: selecting an appropriate region, wherein the region is provided with an Intranet and an Internet; determining an Internet computer serving as a time output server, logging in a national time service center of which the IP (Internet Protocol) address is 210.72.145.44 once every hour, comparing and adjusting the time of the time output server, transmitting newest time data to embedded Bluetooth, and instantly transmitting the time data after the Bluetooth receives the time data; determining an Intranet computer serving as a time server, and receiving time data through the embedded Bluetooth; comparing and adjusting the time of the time server; and realizing time synchronization under the condition of mutually independent Intranet and Internet. One IP address is allocated to the time server in the Intranet, all terminals in the Intranet log in the time server, and the terminal time is compared and adjusted, so that all terminals in the Intranet can be synchronized with the Internet time.
Description
Affiliated technical field
The present invention relates to a kind of method of time synchronized, particularly the method for intranet and extranet time synchronized.
Background technology
The method of known outer net time synchronized is: computer is logined the IP address 210.72.145.44 at national time service center, uses Network Time Protocol can allow computer automatically and the time synchronized on the server.Thereby keep correct time.The method of Intranet time synchronized is: a time server is set and distributes to IP address of this server, network termination is all logined the Intranet time server in all, thereby makes the Intranet time synchronized.This method only makes the Intranet time synchronized, but can there are differences with time at outer net or national time service center.The other method of Intranet time synchronized is: purchase gps satellite server lock in time and distribute to IP address of this server, network termination is all logined the Intranet time server in all, thereby makes the Intranet time synchronized.Because the gps satellite time is consistent with the time at national time service center, so this method can realize the time synchronized of intranet and extranet.Under the situation that intranet and extranet can be communicated with, adopt two card logins can realize the intranet and extranet time synchronized.Use gps satellite server lock in time can make the intranet and extranet time synchronized under the situation that can not be communicated with owing to information security, reason intranet and extranet such as maintain secrecy, but this method is to purchase gps satellite server lock in time.The method that does not also have at present the intranet and extranet time synchronized of more convenient economy.
Summary of the invention
Task of the present invention is to find a kind of method of new intranet and extranet time synchronized, and is promptly convenient and swift economical and practical again, satisfies safe and secret requirement simultaneously, realizes the intranet and extranet time synchronized under the disconnected situation of intranet and extranet.
The technical solution adopted for the present invention to solve the technical problems is: select a suitable zone, zone intranet and extranet are separate is not communicated with for this, and definite outer net computer is the time export server in this zone; By built-in computer bluetooth output time data.Determine that in the same area an inner net computer is a time server, by the time data that built-in computer bluetooth time of reception export server sends, realizes time synchronized under the separate situation of intranet and extranet.In Intranet, distribute to IP address of time server, the equal login time server of network termination in all, thus make all terminals of Intranet and outer net time synchronized.Concrete grammar is as follows:
One, select a suitable zone, existing Intranet has outer net again in this zone, and because of safe and secret requirement, intranet and extranet are separate not to be communicated with.
Two, determine that in above-mentioned zone an outer net computer is the time export server; IP address 210.72.145.44 that computer per hour logins national time service center is set once, the time of export server is adjusted in comparison; And up-to-date time data is sent to embedded with bluetooth.
Three, adjust the setting of built-in computer bluetooth, in time of receipt (T of R) transmitting time data immediately during data.
Four, determine that in above-mentioned the same area an inner net computer is a time server, by built-in computer bluetooth time of reception data; The time of Intranet time server is adjusted in comparison; Under the separate situation of intranet and extranet, realize time synchronized.
Five, in Intranet, distribute to IP address of time server, the equal login time server of network termination in all, terminal time is adjusted in comparison, thereby makes all terminals of Intranet and outer net time synchronized.
The invention has the beneficial effects as follows: under the separate situation of intranet and extranet, realize the intranet and extranet time synchronized, and need not purchase special-purpose time server, convenient to use, economical and practical.
Embodiment
Security protection video monitoring net is the Intranet of maintaining secrecy relatively.Government's net is an outer net.In office, select government's net computer A as the time export server; IP address 210.72.145.44 that computer per hour logins national time service center is set once, the time of comparison adjustment time export server; And up-to-date time data is sent to embedded with bluetooth.Adjust the setting of computer A embedded with bluetooth, in time of receipt (T of R) transmitting time data immediately during data.Determine that in same office a security protection video monitoring net computer B is a time server, by computer B embedded with bluetooth time of reception data; The time of Intranet time server is adjusted in comparison; Under the separate situation of security protection video monitoring net and government net, realize time synchronized.In security protection video monitoring net, distribute to IP address of time server, the equal login time server of the terminal of all security protection video monitoring nets, terminal time is adjusted in comparison, thereby makes all terminals of security protection video monitoring net and government's net time synchronized.
Claims (1)
1. the method for a new intranet and extranet time synchronized is to select a suitable zone, and existing Intranet has outer net again in this zone; Determine that an outer net computer is the time export server; Determine that an inner net computer is a time server; By built-in computer Bluetooth transmission time data, under the separate situation of intranet and extranet, realize time synchronized; It is characterized in that described Intranet outer net is separate is not communicated with; The IP address 210.72.145.44 that described time export server is per hour logined national time service center once, the time of export server is adjusted in comparison; And up-to-date time data is sent to embedded with bluetooth, bluetooth time of receipt (T of R) transmitting time data immediately during data; Described time server is by embedded with bluetooth time of reception data; The time of time server is adjusted in comparison; Under the separate situation of intranet and extranet, realize time synchronized.
