Description
Technical field
The present invention relates to the communications field, more particularly to a kind of data is activation of asynchronous transmission and the method and device of reception.
Background technology
Current radio communication function is a function for standard configuration for panel computer, smart mobile phone etc..Use mobile phone
Radio communication function come manipulate other electronic functionalities also become electronic equipment set manufacturer design electronic equipment when need
The important step to be considered.Wireless module is installed in the electronic device to realize that the radio function of electronic equipment is to solve at present
A certainly approach of problem above.One most basic method is exactly to realize wireless work(using wireless chip in the electronic device
Can, but this mode is relatively costly, is generally used for the radio communication of performance electric room higher.
Another common method is exactly to be changed by the ripe wireless-wire communication of technology in the market
Module realizes radio communication function.Will not be very big to the change on electronic equipment hardware using such technology, so develop
Cost it is relatively low and develop cycle it is also relatively short, be used directly for high speed Wireless Telecom Equipment and low speed it is wired
The foundation of the direct radio communication of communication equipment.But, existing wireless-wire communication modular converter only provides hardware and establishment
The method of communication link, does not provide that scheme solves the Wireless Telecom Equipment of high speed and the wire communication facility of low speed is being used
Communication interaction coordination problem, the i.e. problem of communication speed difference.And the problem person of needing to use oneself design that communication interaction is coordinated
Communication protocol is solved.
During design communication protocol, a kind of relatively common communication protocol is synchronous communications protocol.It is required that hair receives both sides having
With frequency with the synchronizing clock signals of phase, only specific synchronization character need to be added in the foremost of transmission message, hair is received both sides and build
It is vertical synchronous, hereafter just sent by turn under the control of synchronised clock/received.It is characterized in that when carrying out data transmission, send and
Receiving both sides will keep complete synchronization, it is therefore desirable to receive and transmission equipment must use same clock.Its advantage can be
Realize high speed, the transmission of the data of Large Copacity.But meanwhile, it also requires that generation clock and receives clock and keeps stringent synchronization,
Hardware is complicated simultaneously.And the inherently asynchronous low cost of radio communication is being carried out using wireless-wire communication modular converter
Solution, if realizing communication with synchronous communications protocol, will significantly be transformed and cost hardware and software
It is more expensive, it is clear that unreasonable.So when the communication protocol of wireless-wire communication modular converter is designed, typically will not be using synchronous
Communication protocol.
Another relatively common communication protocol is asynchronous communications protocol.The main structure for having used asynchronous transmission of its design
Make, constructed by asynchronous transmission, it is to avoid the requirement of clock stringent synchronization is needed in synchronous communication, so as to reducing design difficulty
With the complexity of hardware, while cost is relatively low.
Asynchronous transmission there is also two potential problems.One is asynchronous transmission needs recipient using spcial character to control
Transmission equipment processed or the data flow of computer transmission.When recipient can not continue to data, an XOFF control word is sent
Symbol tells that sender stops transmission；When transmission can recover, retransmit an XON character to notify sender.So dock
Debit necessarily there are certain requirements in disposal ability, and data are more, and requirement is higher, and the computational load of recipient is also bigger.Its
Two is that recipient is not aware that when data can reach.It detects that data and before responding, first ratio
Spy passes by.Therefore, the information of each asynchronous transmission is all started with a start bit, and it notifies that receiving side data has been arrived
Reach, this just gives the time of recipient's response, reception and data cached bit；In the end of transmission, a stop position is represented
This termination of transmission information.Because so each information adds " synchronization " information, therefore generates more expense.Example
Such as, data transfer bit of every eight bits additionally will transmit 2 bits as synchronizing information more, and total traffic load is increased by
25%.
So in general, generally, asynchronous transmission problem for the low-speed device of volume of transmitted data very little
Less, but for the very big high-speed equipment of those volumes of transmitted data, the load when computational load of recipient and transmission increases
Value is just quite serious, ultimately results in communication efficiency low.If when for volume of transmitted data larger equipment, to consider
The defect for overcoming asynchronous transmission to construct is needed, the load of equipment when reducing communication reduces the consumption of data in communication, so as to be lifted
The efficiency of communication.

Specific embodiment
Fig. 1 is refer to, Fig. 1 shows a kind of example of asynchronous transmission, and wherein panel computer or smart mobile phone 101 has and pass through
Wireless communication module thereon controls the demand of the electronic equipments such as all-in-one 102.Generally, due to electronics such as all-in-ones
Equipment 102 only assembles wire communication module, such as UART or SPI.The data of panel computer or the wireless communication module of smart mobile phone 101
Transmission rate is higher than the message transmission rate of the wire communication module of the electronic equipments such as all-in-one 102, is at this moment necessary to set
Communication protocol is counted to meet the demand of above two communication between devices.
In order to meet above-mentioned similar communication requirement, the present invention provides a kind of method of data is activation, refer to Fig. 2, Fig. 2
A kind of method one side flow chart of data is activation of the invention is shown, the method for data is activation includes：
Step 201：In response to receiving ready signal, data to be sent are determined whether, receive ready signal and indicate communication
The unlatching of window；
Step 202：If there are data to be sent, judge the data volume of data to be sent whether less than or equal to volume of transmitted data
Threshold value；
Step 203：If it is not, the part for then intercepting the data to be sent according to volume of transmitted data threshold value is transmitted,
Data to be sent when remaining data is opened as next communication window, and send the unfinished designator of data transfer.
In the above method, sender will not active sending signal, but the ready signal to be received such as need, receive and prepare letter
Number show that recipient has performed reception and prepared.
After reception ready signal is obtained, sender also needs the size of the data volume for judging plan transmission data, if according to amount greatly
In volume of transmitted data threshold value, then the part for intercepting the data to be sent according to volume of transmitted data threshold value is transmitted.
Volume of transmitted data threshold value herein can set according to the data receiver of recipient and processing speed, that is to say, that
In a communication window, the data of volume of transmitted data threshold value are at most only sent, receive in time and locate to enable the recipient to
Reason.
Using the data after interception as data to be sent, intend being sent when next communication window arrives.When generation data
During intercept operation, send data transfer and do not complete designator, to inform that receiving side data is not transmitted also, recipient may
Lower secondary data is also needed to wait for come after obtaining complete data, then data are processed.
The data volume that sender intends transmission is probably many twices of volume of transmitted data threshold value, now in first communication window
Interior transmitted data amount is equal to the data of volume of transmitted data threshold value, also needs transmitted data amount to be equal to data transfer in second window
Measure threshold value data, now data be not still transmitted, continue send data transfer do not complete designator, until third time
Data transfer can be completed.
If the data volume that sender intends transmission be volume of transmitted data threshold value three times are more and during the above, the process of data is activation
With data volume be volume of transmitted data threshold value twice it is many when situation similarly, by that analogy.
In one embodiment, when the data volume of data to be sent is less than or equal to volume of transmitted data threshold value, then directly transmit complete
The data to be sent in portion.In this case, the data volume of actual plan transmission is divided into two kinds of situations：
The first situation is that the data volume of actual plan transmission is less than or equal to volume of transmitted data threshold value, now in present communications
Window is to complete the transmission to data.
Second situation is that the data volume of actual plan transmission is more than volume of transmitted data threshold value, but in communication window before
It is intraoral to have been completed that partial data is transmitted, data of a data left amount less than or equal to volume of transmitted data threshold value in current window
Transmission is needed, the transmission to data is also completed in present communications window.
Above-mentioned two situations all show that data transfer has been completed, and in one embodiment, after the completion of data transfer, send number
According to signal is transmitted, inform that receiving side data has been transmitted, recipient can be with start to process data.
In one embodiment, in response to receiving ready signal, but when not having outgoing data, sign off designator is sent.
The sending method of the above-mentioned data of correspondence, the present invention provides a kind of method of reseptance of data, refer to Fig. 3, and Fig. 3 shows
A kind of flow chart of the method one side of data receiver of the invention, the method for data receiver includes：
Step 301：Sent to transmitting terminal and receive ready signal, with open communication window；
Step 302：In response to receiving ready signal, data to be received are determined whether；
Step 303：If so, then receiving the data from transmitting terminal, the data volume of received data is less than or equal to number
According to transmission quantity threshold value.
Receiving terminal sends to transmitting terminal and receives ready signal in the case where it is got ready, and shows its capable reception
Data, communication window is opened.
In the case where communication window is opened, receiving terminal determines whether data to be received, as long as now having to be received
Data, then receiving terminal directly receives data, but the data volume of the data for receiving is less than or equal to volume of transmitted data threshold value.
In one embodiment, in response to receiving ready signal, but during without data to be received, sign off designator is received.
Because the data volume for intending the data of transmission is unknown, in one embodiment, receiving terminal also needs to judge whether to receive number
According to being transmitted designator, and then judge whether to have received complete data.The sending method that data transfer completes symbol is the same
The description of face data transmission method for uplink part.
Receiving terminal judges that whether data transfer is received in present communications window completes designator, passes when data are received
When being totally lost into designator, there are two kinds of situations.
The first situation is that the data volume of actual plan transmission is less than or equal to volume of transmitted data threshold value, now last logical
Or not being transmitted across data completely in letter window, that is, sign off designator can be received in a upper window, or
Data transfer once is completed in a upper communication window, data transfer can be received and completed designator, in present communications
The reception to data is once just completed in window.Fig. 4 is refer to, Fig. 4 shows that the data volume for intending transmission is less than or equal to data
The situation of designator is received during transmission quantity threshold value, present communications window (n-th communication window), N-1 is respectively illustrated and is led to
Letter window, the designator reception condition of the N-2 communication window.Due to have received complete data, in one embodiment,
Receiving terminal can be processed directly data.
Second situation is that the data volume of actual plan transmission is more than volume of transmitted data threshold value, in communication window before
Inside have been completed that partial data is transmitted, a data left amount is needed less than or equal to the data of volume of transmitted data threshold value in current window
Transmit, can now be received in present communications window data transfer complete designator, and previous communication window in
Data transfer will not be received and complete designator, will not also receive sign off designator.
Now need by each window reception to data combine to form partial data, in one embodiment, once connect preceding
Receive the data of transmission in the communication window that data transfer is completed between the corresponding communication window of designator and present communications window
Partial data is combined into the data received in present communications window, then data processing is carried out to partial data.
