GPS Beidou clock server （NTP Network clock system ） Construction deployment plan
GPS Beidou clock server （NTP Network clock system ） Construction deployment plan
One 、 Construction introduction ：
At your request , Provided by our company GPS Beidou satellite clock server （NTP Clock synchronization server ）, In order to solve the time synchronization problem of the whole network computer system ;

Two 、 Construction instructions ：
1． Before using this device , Please carefully read the user manual and other user instructions accompanying the device .
2． Non professionals are not allowed to open the chassis at will , Do not change any jumper settings , So as not to affect the normal operation of the device .
3． Avoid wire ends （ silk ） Or other metal objects fall into the chassis , To prevent short circuit or other faults .
4． During the operation of the device , Non professionals are not allowed to press the buttons on the front panel of the device at will .
5． Before using the device , Please ground the grounding terminal on the rear panel of the device reliably .
6． Before connecting the power , Please confirm the power requirements on the rear panel of the device and the user manual , Connect the power supply as required .
7． Different types of timing signal output signal voltage 、 The current amplitude is different , Before connecting the signal to the timed device, please confirm whether the type of the connected timed signal is correct , So as not to damage the timed device interface .

3、 ... and 、 Construction description ：
The construction is generally divided into three parts ： Antenna erection and equipment network configuration 、 Network client configuration ;
1、 Antenna erection
When the satellite antenna is erected , First install the antenna head on the antenna support ( Options ) On , Then fix the antenna bracket on the top of the building with expansion bolts , Angle brackets can be used when necessary according to installation conditions ( Options ), Pictured 1 Shown . The antenna head should be installed outdoors , The installation position should have a wide view , Install on the roof as much as possible , In principle, if you look up the antenna head, you can see 360° The sky of . Then lay the cable of the antenna from top to bottom . The turning radius of antenna cable laying is not easy to be too small , When punching, pay attention to wrap the joint . The antenna is designed strictly according to the length of the cable , Don't cut 、 extend 、 Shorten or add joints , Otherwise, the receiving effect will be seriously affected, and even the signal will not be received .
The antenna should avoid the hillside as much as possible 、 The woods 、 High rise buildings 、 iron tower 、 The blocking of antenna beam by high voltage transmission line . There should be enough horizon in the direction of the main beam of the antenna , There should be as wide a viewing angle as possible in front of the antenna . The general requirements are based on the antenna base point , The angle to the highest point of the obstacle is less than 10 degree .
The antenna should be erected away from the air outlet , To reduce the wind load of the antenna . In Thunderstorm areas , The erection position of antenna should avoid the place where lightning strikes frequently , The antenna head should be placed in the power plant / Within the lightning protection range of substation lightning rod . When the antenna is installed on the roof , As long as you have enough vision , The smaller the distance above the roof, the better . meanwhile , Antenna should be installed with special lightning arrester as far as possible , Before the thunderstorm season comes, we must carefully check whether the lightning protection and grounding system is in good condition （ The special lightning arrester is an optional device ）.
2、 Device network port configuration
◆ Install the configuration software on the CD , And refer to the attached instructions .
3、 Client configuration （ With winxp System as an example ）
◆ Double click the time area in the lower right corner of the taskbar –>internet Time –> The server fills 192.168.0. X, Select automatic and Internet Time server synchronization , Press " Update immediately " It can be synchronized directly .
◆ Modify registry , At the beginning ----- Type while running ：regedit enter , You can edit the registry .
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient] “SpecialPollInterval”=dword:xxxxxxxx（ Synchronization interval . Company ： second , Default to decimal 604800, A week ）
If you want to change it to 1 Synchronize every hour , hold dword The value after is changed to 3600 that will do .
If you want to change it to 3 Sync once a minute , hold dword The value after is changed to 180 that will do .
