Accompanying drawing explanation
Fig. 1 is the flow chart of a kind of big data quantity transmission method based on Big Dipper communication that the present invention proposes.
Detailed description of the invention
With reference to Fig. 1, a kind of big data quantity transmission method based on Big Dipper communication that the present invention proposes, comprise the following steps.
S1, acquisition data to be transmitted amount.
S2, judge the prescribed limits of the data field length whether length of data to be transmitted amount can transmit more than single. At present, the civilian agreement of current Big Dipper communication, the frequency of transmission and the data volume of transmission there is certain restriction, transmission frequency is 60 seconds every time, be 1680bit in the message data amount once transmitted, so, in present embodiment, it is stipulated that limit value is set to 1680bit.
S31, if less than or equal to prescribed limits, then set up transmission unit, each transmission unit all include a data field and one control territory.
S32, calculate the data field content of transmission unit according to data to be transmitted gauge and insert data field.
S33, controlling to insert in territory data field length information and control information, control information is for indicating the number of transmissions of transmission unit. This step is directed to single transmission, so control information is used for indicating single transmission.
S34, according to control information, transmission unit is transmitted.
In present embodiment, for the transmitted data amount that data length is shorter, it is transmitted after directly adding control information, namely improves data transmission efficiency, by control information, data can be verified again, improve the safety of data transmission.
S41, if greater than prescribed limits, then data volume waiting for transmission is divided into multiple data segment.
S42, set up multiple transmission unit being not more than prescribed limits with data segment data length one to one, each transmission unit all include a data field and one control territory.
S43, calculate the data field content of corresponding transmission unit according to data segment and insert data field.
In present embodiment, data segment and transmission unit one_to_one corresponding, thus multiple transmission unit can be divided into by data volume waiting for transmission to carry out segmentation transmission, it is to avoid the data loss problem caused owing to data volume is excessive.
S44, controlling to insert in territory data field length information and control information, control information is for indicating the number of transmissions of corresponding transmission unit and order.
In this step, indicate with data field length, can find that in data field, data, with or without loss, reduce the distortion factor of data transmission, improve the reliability and security of data transmission in time. In present embodiment, by controlling the number of transmissions of information indicating transmission unit and order, after being conducive to being transmitted, the integration to multiple data segments, reacquire data volume, it is ensured that the integrity of data transmission.
S45, according to control information, transmission unit is transmitted.
S46, according to control information judge currently complete transmission transmission unit whether be last transmission unit.
S47 is if it is, extracted the control information of each transmission unit of transmission. If it is not, then proceed data transmission.
S48, according to extract control information determine whether that transmission unit is lost in transmitting procedure. In step S44, the control information arranged in each transmission unit should be continuous or have continuous information, in order to the integration of data segment. So, after data complete, the integrity of data segment can be judged according to the information of control,
S49 is if it has, then abandon the transmission unit of current acquisition or the data cell lost is carried out secondary transmission. Specifically, this step can be: abandons the transmission unit of current acquisition, and returns step S42 or S45, all data volumes are transmitted again; Or, calculate the order of transmission of the transmission unit lost according to the control information of the transmission unit being transmitted, and again transmit the transmission unit of loss according to order of transmission.
In this step, by again transmitting or the mode of compensation data is to occurring that the data segment lost makes up, advantageously ensure that integrity and verity that data transmit.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
