Reliability.
Need to be its corresponding shape of configuration to ensure that the business scenario normally runs for complex business scenario
State machine, such as state machine with hall exercise scene are as shown in Figure 4.
S2, the state according to the state machine synchronization teacher side and student side.Specially：Obtained from the state machine of student side
The current state of student side is taken, first state is obtained；Shape corresponding with the first state is obtained from the state machine of teacher side
State, obtains the second state；The current state of teacher side is obtained from the state machine of teacher side, the third state is obtained；Teacher side root
According to the teacher side state machine to student side send from second State Transferring to the third state first instruction and
First data；Judge it is described first instruction whether any state by teacher side from after the third state or the third state change to
The instruction that any state before final state or final state is triggered, if so, not performing first instruction then.
For example, the first student side disconnects the connection with teacher side due to factors such as unstable networks, the first student side is hung up
The state machine of itself.Before disconnecting, the first student side is in state " in inscribing ".When the first student side reconnects teacher
During end, teacher side has turned to " teacher has wound " state.Therefore, according to the state machine for practising scene with hall, the first student side is same
Step is from " in inscribing " state to the state " teacher has wound " state.Specially：Student continues to inscribe in the first student side,
After student does topic and finish in the first student side, answer is submitted to teacher side, and go to the state of " student has been filed on answer ".And
Paper is submitted to teacher side, perform operation of handing in an examination paper.Teacher side sends winding instruction, obtains the paper that student side is submitted to, student side
Go to " teacher has wound " state.
When the first student side is in the state for recovering synchronous, other student sides are still pressing the rule of state machine just with teacher side
Often operating.Now, teacher side can also be sent to the first student side by the instruction that State Transferring is triggered.First student side judges
The instruction being currently received whether the instruction triggered by the state after " teacher has wound " by teacher side, if so, then first learn
Causing trouble wouldn't perform the instruction.Such as, during the first student side recovers synchronization, teacher side is issued " teacher announces result "
Instruction, the student side in addition to the first student side has received paper answer, has gone to " student has obtained result " state, teacher side
" student has obtained result " state is also gone to after paper answer is sent.But, now, the first student side not yet completes to recover synchronous
Operation, therefore, the first student side is receiving the instruction of " teacher announces result " that teacher side is sent due to normal State Transferring
When, the command signal is kept in, after the completion of simultaneously operating to be restored, the first student side performs corresponding reception and instructs, and changes extremely
" student has obtained result " state.

Source jumps to corresponding state again after receiving.Specially：
Student side receives the second instruction that teacher side sends；
Student side is judged with the presence or absence of the data needed for performing second instruction, if it is not, then：
Student side asks the second data corresponding with the described second instruction to teacher side；
After student side receives second data, second instruction is performed.
For example, teacher side switchs to " doing topic timing " state from " transmission exercise " state.Teacher side sends to student side and counts
Shi Zhiling, due to the influence of the factors such as network speed, the data resource of corresponding exercise is not also complete to be received, and student cannot at partial students end
Start to inscribe, therefore riming instructions wouldn't be performed, after the data resource of corresponding exercise is completely received, then perform riming instructions simultaneously
Go to " doing topic timing " state.If when student side switchs to " doing topic timing " state, teacher side turns from " doing topic timing " state
Be " teacher has wound " state, then student side according to state machine synchronization from " doing topic timing " state to " teacher has wound " state it
Between state.
Additionally, during student side is synchronous with teacher side, also needing to preserve the current shape of the state machine of student side in real time
State.
If student side is only because network factors are disconnected with the teacher side short time, state machine can automatically save current shape
State.But, if student side need to restart system due to failure, after system is restarted, the state of state machine can return to state.
Therefore, the current state of state machine is first synchronized to the last state of the student side preserved before system reboot, is conducive to improving extensive
The efficiency of multiple state synchronized.
In sum, the present invention is provided a kind of online class teaching synchronous method and system based on state machine, pass through
According to online class impart knowledge to students service logic configuration teacher side and student side state machine so that when student side because network etc. other
After factor goes offline, in reconnect during teacher side, the current state of the state machine of teacher side and student side can be respectively obtained, according to
State machine synchronization teacher side and student side, so as to improve the reliability of online class teaching.The present invention also provides one kind and is based on
