The data slot to be sent is sent according to position grid 111, and data slot transmission is kept to continue the second preset time.In this reality
It applies in example, second preset time could be provided as 30ms-50ms.
Referring once again to Fig. 8, with t1And t2For moment, the data sending device 100 is in t2Moment judgement will be sent
Data slot and t1Whether transmission data segment is identical when the moment.t1The data slot that moment has sent is 1101, t2Moment will
The data slot to be sent is 0010.The data slot that two moment send is different, then the data sending device 100 is in t2When
It carves and sends 0010, and the signal is persistently sent to t3Moment.
Situation two, when the data slot that will be sent is identical as the data slot that upper one has sent, by described
Flag bit grid 112 sends a transmission idler Pulse signal, and the transmission idler Pulse signal is sent completely subsequent supervention and send institute
Transmission useful signal is stated, while the data slot that will be sent is sent by the flag bit grid 112, and keeps the data
Segment transmission continues the second preset time.Wherein, the transmission idler Pulse signal is the arteries and veins of the transmission invalid signals
Punching, in the present embodiment, the transmission idler Pulse signal set 1 pulse for the flag bit one, i.e., the described flag bit grid
One blanking pulse of lattice 112.
Referring once again to Fig. 8, with t7And t8For moment, the data sending device 100t8When judge will transmission data
Segment and t7Whether transmission data segment is identical when the moment.t7The data slot that moment has sent is 1101, t8Moment will be sent out
The data slot sent is 1101.The data slot that two moment send is identical, then the data sending device 100 passes through the mark
Will position grid 112 sends a transmission idler Pulse signal.The transmission idler Pulse signal be sent completely subsequent supervention send it is described
Useful signal is transmitted, while transmission 1101 is continued by the data bit grid 111, and the signal is persistently sent to t9When
It carves.
Step S130, the flag bit grid 112 that the data sink 200 detects the data sending device 100 are sent out
The transmission state signal gone out.
Specifically, the data sink 200 detects the transmission state by the flag bit receiving terminal 212 and believes
Number.
Step S140, the data sink 200 is when detecting the transmission useful signal, successively from the data
Position grid 111 reads data slot.
Specifically, when the data sink 200 detects the transmission useful signal, start to receive the data
The data slot that position grid 111 is sent.After receiving the data slot every time, storage has connect the data sink 200

Section, judges whether the data slot changes again.In the present embodiment, the third preset time could be provided as 3ms-
10ms。
When the data slot does not change again, then it is assumed that the data slot after variation is one and stable just firmly believes
Number, the data sink 200 stores the data slot.
When the data slot changes again, then it is assumed that the variation of the data slot may be that a data are trembled
Dynamic, the data sink 200 re-reads the data slot that the data bit receiving terminal 211 receives, while resetting simultaneously
Start the timer.
Situation two will be current after detecting that the flag bit receiving terminal 212 receives the transmission idler Pulse signal
The data slot that the data bit receiving terminal 211 receives is as new data slot and storage.
The flag bit receiving terminal 212 is when detecting the transmission idler Pulse signal, the data sink 200

200 using the data slot being currently received as new data slot and storage.
Step S150, the data sending device 100 pass through the flag bit grid after the data slot is sent completely
Lattice 112 send the transmission invalid signals, and the transmission invalid signals is made to keep one first preset time.
Referring once again to Fig. 8, in tendMoment, the data sending device 100 complete the transmission of all data slots, will
The mark position 1, characterization transmission invalid signals, and the transmission invalid signals are kept into first preset time, terminate
This data transmission.In the present embodiment, first preset time is more than the third preset time and the transmission is invalid
Pulse signal duration, first preset time could be provided as being more than 250ms.
Step S160, the data sink 200 are detecting that the transmission invalid signals duration is more than first
When preset time, stop receiving the data slot, and the data slot received is synthesized partial data.
The data sink 200 is when receiving the transmission invalid signals duration and being more than described first default
Between when, it is believed that data transmission is completed in the data sending device 100, then stops receiving data slot, and will have received
Data slot synthesizes complete data according to the sequence of reception.
Further, in the another embodiment in this implementation column, the data sending device 100 can also pass through
The data bit grid 111 shows that different colors, the data bit grid 111 show different colors to characterize when lighting
The different value of the data bit.Lighting or extinguishing for the flag bit grid 112 indicates the different value of flag bit, different to characterize
