Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Embodiments provide a kind of air traffic control radar information test method, shown in Figure 1, comprise step:
Step S110, judges host-host protocol according to synchronization character.
In embodiments of the present invention, the present invention adopts the synchronization character of two kinds of host-host protocols to judge.Different according to the synchronization character that different synchronous transmission agreement is applied, and there is the feature that mode is different in synchronization character, take, using the synchronization character of differing transmission protocols as keyword, whether to occur keyword in Query Information respectively, carry out the judgement of air traffic control radar information host-host protocol.
Transmission due to air traffic control radar information adopts BSC (binary synchronous communication code substantially, and HDLC (High-Level Data Link Control BinarySynchronousCommunication), High-LevelDataLinkControl) host-host protocol, therefore, in embodiments of the present invention, determine that the mode of host-host protocol is by synchronization character: search in message bit stream and whether occur binary number form synchronization character 0011,0010, then be judged to be BSC host-host protocol; No, search in message bit stream and whether occur binary number form synchronization character 0111,1110, be, be then judged to be HDLC host-host protocol.
Particularly, first with the synchronization character binary number form 0011,0010 of BSC host-host protocol for keyword, search it and whether occur in message bit stream, if keyword is with the appearance of two or more continuous print modes, be then judged to be BSC host-host protocol; Otherwise with the synchronization character binary form 0111,1110 of HDLC host-host protocol for keyword, search it and whether occur in message bit stream, as occurred then being judged to be HDLC host-host protocol.
Step S111, according to the result of determination of host-host protocol, adds the agreement stamp for distinguishing differing transmission protocols type at the Frame afterbody that this host-host protocol is corresponding, the data of the stamp of transmit band protocols having afterwards.
Described agreement stamp, for distinguishing different host-host protocols, different host-host protocols has different agreement stamps, the transmission of data flow and receiving terminal are arranged agreement stamp and represented protocol type thereof, like this, receiving terminal, for being with the data of protocols having stamp without the need to again carrying out agreement judgement, directly uniquely determines this protocol type according to agreement stamp when carrying out Data Analysis.
After host-host protocol judgement terminates, the afterbody of the Frame in the data flow being judged to be BSC host-host protocol increases by the first agreement stamp; The afterbody of the Frame be judged to be in the data flow of HDLC host-host protocol is increased second protocol stamp.
Particularly, for BSC agreement and HDLC agreement, first receive complete air traffic control radar information Frame with judged synchronous transmission agreement.If the host-host protocol of the data received is as being BSC, then by binary number 0000,0001 increases Frame afterbody as the first agreement stamp, represent information transmission protocol be BSC host-host protocol, as being HDLC, then at Frame afterbody with Binary Zero 000,0010 number increases second protocol stamp, represent that information transmission protocol is HDLC host-host protocol, namely described first agreement stamp binary number representation is 0000,0001; Described second protocol stamp binary number representation is 0000,0010.
Afterwards, the data flow with described first agreement stamp and/or described second protocol stamp is broadcasted by wireless ethernet according to network udp protocol by complete.
