Description
Technical field
It is the present invention relates to standardization examination field, in particular to a kind of for standardizing the satellite time transfer clock system in examination hall
System.
Background technique
2009 the Ministry of Education tissue national ordinary higher learning school's entrance examination work video telephone can on, the Ministry of Education emphasizes,
The wireless communication tool of the timing forms such as wrist-watch is utilized to practise fraud in order to take precautions against, all examination halls will be equipped with wall clock, and examinee must not be by hand
The time sets such as table bring examination hall into.In subsequent several years, the Educational Examinations Authority in multiple areas puts into effect relevant regulations for wrist-watch successively
It is classified as the article for forbidding bringing into examination hall.
2011, the Ministry of Education issued " national education examinations standardize examination point specification ", and the inside defines " to be arranged in examination hall
Clock, do not influence examination be normally carried out under the premise of, provide time reference for examinee ".
Each examination hall time precisely shows, runs simultaneously, reliability service is one of important foundation for guaranteeing that examinee's examination is fair.
The solution of main time showing is quartz clock and radio wave clock currently on the market.However, they have all been exposed much
Problem is mainly shown as:
(1) for quartz clock, when needing manual school, and accumulated time error is unable to self-correcting；
(2) for radio wave clock, signal reception has region limitation, and signal is by the shadow of the factors such as weather, geography and building structure
It rings；
It (3) is not constantly synchronous；
(4) it can not know clock work state；
(5) it can not be managed collectively.
Summary of the invention
Object of the present invention is to: establishing a set of can really ensure that each examination hall time precisely runs, runs simultaneously and reliability service
Satellite time transfer clock system.The solution combined using satellite time synchronization technology and information technology is really solved
When the clock difficulty school of examination hall, examination hall time difficulty is synchronous and the problems such as examination hall clock operating status is uncontrollable.
The technical scheme is that
A kind of satellite time transfer clock system for examination hall, including satellite time transfer module, management server, interchanger and be distributed in
The synchronised clock in each examination hall；The satellite time transfer module receives satellite-signal, and it is complete to be connected to management server by the communications cable
At the time synchronization of server end, management server connects the synchronised clock in each examination hall by interchanger, is realized by IP agreement
The time synchronization of each synchronised clock.
Preferably, the management server is connected with management PC.
Preferably, the interchanger also passes through core switch, internet is connected to higher level command centre.
Preferably, the internet that the core switch is connect with higher level command centre has protecting wall.
Preferably, the received satellite-signal of satellite time transfer module is GPS or Big Dipper satellite signal, supports GPS and north
Struggle against satellite-signal synchronization process.
Preferably, the management server realizes time synchronization using satellite synchronization time service+Network Time Protocol；
Preferably, the satellite time transfer module is connected to the communications cable of management server using RS232 bus.
The invention has the advantages that
1, the present invention takes the lead in using Time synchronization technique is realized based on satellite synchronization time service+Network Time Protocol in examination hall, really in fact
Show and has precisely constantly synchronized；
2, present system is limited without using area, is not influenced by geographical environment and weather etc.；
3, the present invention takes the lead in realizing the automation of clock, intelligent management in examination；
4, the present invention supports GPS and Big Dipper satellite signal synchronization process；
5, automated monitor operating status of the present invention, automatic alarm prompts when unit exception, is accurately positioned to fault point；
6, the time is normally shown after suspension of the present invention, and internal self-clocking is switched to after power-off；
7, the present invention booting automatic self, platform can centralized control carry out charactron self-test, it is ensured that the time is accurate and reliable；
8, Embedded System Design of the present invention, system can be stable.
