To the position of head at the moment, the data information of the virtual reality for will be handled in 211 video card of main computer unit high speed, low latency
It is shown in user at the moment；VR interactive unit 213 includes two wireless controllers, when student is carrying out the experience of virtual reality content
When, every hand is one hand-held, and true both hands are simulated in the environment of virtual reality and are operated；VR positioning unit 214 wraps
Include two infrared sensors diagonally placed, rectangle composed by the infrared sensor that station is diagonally placed at two when student's use
In regional scope, by the transmitting and reception of 213 infrared ray of VR display unit 212 and VR interactive unit, the interaction of data is obtained
The XYZ three-dimensional information of VR glasses and wireless controller is got, the accurate positionin acted to student is realized, to improve VR in elementary teaching
In effect.
As shown in Figure 1, controller 22 includes two kinds of operation modes of automatic control unit and manual control unit, wherein automatically
Editor has information storage node in control unit, the content that can be played according to administrator end 2 to the reading of student side 1 record and in real time
The information for carrying out statistics and intervening act stores, and the purpose of automatic control is realized with this.
As shown in Figure 1, server end 23 include an at least personal computer 231 and at least one using stack algorithm into
The programmable logic controller (PLC) 232 of row data storage, programmable logic controller (PLC) 232 and personal computer 231 communicate to connect reality
Existing data are synchronous, make user that can carry out control operation to programmable logic controller (PLC) 232 by personal computer 231.And it can
The storage data quantity of programmed logic controller 232 is smaller, and uses the interim storing data of stack algorithm, and personal computer 231
Using hard-disc storage, storage data quantity is larger, and programmable logic controller (PLC) 232, which receives, to be synchronized to after new presupposed information
People's computer 231 stores, and to prevent loss of data, while its own realizes the repetition covering of data, i.e., nearest number
If legacy data is replaced in covering according to there is new data to arrive, to realize the iteration of data.
As shown in Figure 1, programmable logic controller (PLC) 232 includes account management unit, Role Management unit, safety management list
Member, resource management module, wherein account management unit is for being managed the account of platform, registration, inquiry including account,
It deletes, modify, disable, lift a ban function；Role Management unit is used to carry out account the distribution of system permission, including student side 1
With the division of 2 right of administrator end；Security managing unit is used to carry out safety management to the login situation of account, including singularly
Area logs in alarm, network attack alarm, password modification alarm；Resource management module is used for the resource for being stored in server end 23
It is managed, video resource, model packet resource, the deletion of audio resource three classes, update including student side 1 and administrator end 2,
Search operation.
As shown in Figure 1, programmable logic controller (PLC) 232 further includes data statistics unit, data-pushing unit, information transfer
Processing unit, wherein data statistics unit for statistics cause trouble 1 login, operation, browsing situation, according to concurrency, region,
Period counts the current and historical data of student side 1；Data-pushing unit is used for according to student side 1 or administrator end 2
The request of transmission pushes related data information to student side 1 or administrator end 2；Information transfer processing unit is used for receiving
Administrator end 2 to the control information and student side 1 that student side 1 is sent to administrator end 2 passback feedback information carry out in
Turn and parse, so that administrator end 2 is carried out data flow with student side 1 and interact.
In order to improve the stability of system, as shown in Figure 1, the friendship that server end 23 and VR equipment 21 pass through handshake
The mutual inspection for mutually carrying out working condition, gives VR equipment 21 1 signals, VR equipment 21 is again when server end 23 starts every time
Feed back a signal to server end 23, which includes the id information of each VR equipment 21,23 pairs of server end feedbacks
Judgement is compared with the correspondence id information in database in signal, in VR equipment 21 there are when problem, or certain symptom occurs and needs
When handling but temporarily will not influence normal operation and the variation of sensor in error range when, make refusal use,
Warning or the instruction information normally enabled.
Information is lost in order to prevent, as shown in Figure 1, personal computer 231 and programmable logic controller (PLC) 232 pass through heartbeat
The interaction of signal carries out the mutual inspection of working condition.Programmable logic controller (PLC) 232 and personal computer 231 are set pre-
If mutually can not receive in the time to square signal, then 232 delay machine of personal computer 231 or programmable logic controller (PLC) is judged,
Personal computer 231 or programmable logic controller (PLC) 232 are wherein in the case where side's delay machine, and system is out of service, and waiting is in
The personal computer 231 or programmable logic controller (PLC) 232 of delay machine state are restarted or system continues to run, but data are directly deposited
The personal computer 231 or programmable logic controller (PLC) 232 for entering normal work, after delay machine side restarts, then send data to
Delay machine side.Wherein, judge personal computer 231 or the whether normal preset time of programmable logic controller (PLC) 232 no more than 1 point
Clock.
As shown in Figure 1, being stored with the normal operating parameters of each component in tutoring system in programmable logic controller (PLC) 232
And/or working life information, it can judge whether it needs more according to the normal operating parameters and/or working life information of each component
It changes or repairs, if so, carrying out local warning, realize the warning function to each component working condition, remind user's replacement in advance
Or maintenance, failure is prevented, working efficiency is improved.
Based on the working principle of the tutoring system of VR: after student side 1 logs in VR equipment 21 by account, utilizing VR equipment
21, which carry out content of courses browsing, plays, this sequence of maneuvers is mapped to server end 23 by data flow, and server end 23 is in basis
Claass management person's account carries out data-pushing, and administrator end 2 is by statistics of the server end 23 to data flow, typesetting, to reach
The application scenarios of student side 1 are monitored to administrator end 2；Control command occurs to server end 23, including control from administrator end 2
Command name, control account ID, control command content, server end 23 according to from administrator end 2 transmission come data flow progress
Parsing, then the implementation of student side 1 control command data of corresponding ID is spread defeated.
