Abstract
The invention provides a double-bit-check coding and decoding method, can detect source data error generated due to interference, and effectively guarantees the correct transmission of data so as to solve the error code problem in data transmission with low cost. The method comprises a coding process, a decoding process and a checking process. In the coding process, when a frame of raw data is received, bit by bit logic negation is carried out to each data bit of the frame, the logic negations of the obtained raw data bits are the check bits of raw data bits, and coding is carried out to the raw data by adopting the mode of inserting each check bit of the raw data bits behind each data bit of the frame data. In the decoding process, decoding is carried out to receive coded data, and decoded raw data bits and decoded check data bits are respectively obtained. In the checking process, whether the decoding check bits are the logic negations of decoded raw data is judged, and when the decoding check bits are the logic negations of decoded raw data, the raw data are judged to be correctly transmitted.
Description
Technical field
The present invention relates to a kind of method that guarantees the correct transmission of data, the parity check method of particularly decoding for the dibit encoding of communications.
Background technology
Generally speaking, existing former code and decode mode is thought: as long as guarantee to adopt identical coded system aspect these four of the codings of the coding of coding, result set at the coding that connect to use, database and database server, just Confused－code can not occur.But in the process of the actual transmissions that realizes agreement, metadata element is easy to be subject to the interference of external environment, and causes loss of data or make mistakes.In order to solve the problem of makeing mistakes of data, at present based on former protocols having, adopt the monitoring transmission bearer whether normal, and extend as required the transmission time of data, reduce the error rate of transmission.And, requiring the crucial occasion of error-free transmission, also can carry out the mode that Dual-path backup transmits by two groups of very high equipment of use cost, thus, although can realize the requirement that accuracy is high, the high problem of cost compare that causes the one-level transmission and receive.Therefore, there is the demand of carrying out the high transfer of data of accuracy with lower-cost plain mode.
Summary of the invention
The present invention completes in view of the above problems, and its purpose is to provide a kind of simple and easy method that effectively guarantees the correct transmission of data, can detect the source data mistake that produces because of interference, with the error code problem in low cost solution transfer of data.
The Code And Decode method of the dibit verification that the present invention relates to is characterized in that, comprising:
Coding step, when the former data of frame that receive, each data bit to this frame is carried out inverse by turn, the non-of the former data bit of gained is namely the check digit of this former data bit, employing is inserted the mode of its check digit above-mentioned former data is encoded after each data bit of above-mentioned former data, the later Data-Link of namely encoding is the former data check of former data bit 1 position 1, the former data check of former data bit 2 position 2 ... the serial data form of the former data check of former data bit n position n is encoded to described former data thus;
Decoding step is decoded to the coded data of having carried out that receives, and the former data bit that obtains respectively decoding is conciliate the code check data bit; With
Checking procedure, whether judgement decoding check digit is the non-of the former data bit of decoding, when both consistent, be judged as above-mentioned former data and correctly transmitted.
Code And Decode method according to the dibit verification that the present invention relates to, wherein, in described checking procedure, that the position is carried out in the former data bit of described decoding and described decoding checking data position and computing, when this operation result is not 0, be judged as the former data of described decoding and described former data consistent, when this operation result is 0, be judged as the former data of described decoding and described former data are inconsistent.
Code And Decode method according to the dibit verification that the present invention relates to, wherein, in described checking procedure, because the former data bit of described decoding and described decoding checking data position are one to one, it is the figure place of coded data and for even number, during when the figure place that described coded data detected with for odd number, be judged as described former data and correctly do not transmitted.
According to the Code And Decode method of the dibit verification that the present invention relates to, wherein, also comprise the check errors retransmission steps, when in described checking procedure, after judging that the described former data of frame are not correctly transmitted, require to retransmit the former data of described this frame.
The invention effect
According to the Code And Decode method of the dibit verification that the present invention relates to, provide to detect the mistake that source data produces because of interference, thereby solved at low cost the method for the correct transmission of assurance data of the error code problem in transfer of data.

Embodiment
Below, with reference to accompanying drawing, the execution mode of the Code And Decode method of the dibit verification that the present invention relates to is elaborated.
Fig. 1 is the flow chart for the Code And Decode method that the dibit verification that the present invention relates to is described.The Code And Decode method of the dibit verification that the present invention relates to as shown in Figure 1, comprises following steps: data input step 1, dibit encoding step 2, data transmission step 3, dibit decoding step 4, check errors retransmission steps 5, checking procedure 6 and data output step 7.
At first, in data input step 1, receive former data by the sending part with encoding function, in dibit encoding step 2, this sending part carries out dibit encoding according to the coding method of the dibit verification in present embodiment to the former data that receive.Then, this sending part is in data transmission step 3, to carry out the data after the dibit encoding and be sent to predefined target acceptance division, this target acceptance division is after receiving data, according to the dibit coding/decoding method of setting in present embodiment, the data of coming from the sending part transmission are carried out dibit decoding (dibit decoding step 4).Further, decoded data are carried out verification (checking procedure 6), and according to the result that judges in checking procedure, transfer to respectively check errors retransmission steps 5 and data output step 7.Particularly, mistake appears if the result of verification is former data, send the data re-transmitting instruction to the sending part that sends these data, after this sending part received above-mentioned data re-transmitting instruction, coded data resend (check errors retransmission steps 5).Mistake do not occur if the result of verification is former data, will by the dibit resulting former data of decoding, output to predefined terminal (data output step 7).
In the present embodiment, can former data be weaved into the dibit code through adding the position by software mode or hardware mode, in addition, when being appearred in former data, mistake need to be illustrated to the error message that sending part sends, the present invention does not do restriction to concrete mode, meets dibit code described above as long as can access.Former data select the arbitrary mode in time-division, frequency division, code minute to be processed into the frame structure of standard transmission by characteristics, so that encode, transmit, read, judge, decode, be reduced into former data.
The present invention is realizing than being easier to aspect coding and decoding and transmission by adopting the mode that increases by 1 error detecting code on the basis of former data.Thereby, solved former data in direct transmitting procedure, disturb the problem that forms error code and can't screen, judge, remove due to factors such as external electromagnetic.Compared with prior art, the present invention has simply, low-cost, high efficiency advantage, and can guarantee that the former data of transmitting can not make a mistake.
