Step 102, X level saltus step is persistently detected in receiving port, wherein, X level saltus step being continuously detected is equal To be changed into low level from high level.
In this step, the equipment of the progress data receiver of detection level saltus step can be carried out continuously to the level of receiving port The sample frequency that sampling uses to obtain the change of the level of receiving port, during sampling should be above default minimum standard, protect The authenticity of the level change for the receiving port that card sampling obtains, the level saltus step that can also only obtain receiving port is high level Saltus step is the low level moment.
Step 103, according to the wave sequence feature of N number of wave sequence of default X level saltus step formation and persistently The transmission that time interval between any two level saltus step in the X level saltus step detected calculates a wave sequence is held The continuous time.
In this step, for example, X=4, N=5, the 4 level saltus steps persistently detected as shown in figure iD, then can be according to step The wave sequence feature for 5 wave sequences that the default 4 level saltus steps obtained in 101 are formed, and any two level Time interval between saltus step calculates the transmitting continuous time of a wave sequence, e.g., shown in reference picture 1C, first time saltus step Time interval between second of saltus step is T-T1+T1=T, i.e., the transmitting continuous time of one wave sequence, jumps for the first time The time interval become between third time saltus step into T-T1+T1+T-T1+T1=2T, i.e. two wave sequences it is transmitting continuous when Between, the time interval between third time saltus step and the 4th saltus step is T-T1+T+T2, in known T1, T2 and T proportionate relationship In the case of, you can the transmitting continuous time of a wave sequence is calculated.
In the present embodiment, the biography of a wave sequence is calculated using the time interval between at the time of identical saltus step The defeated duration, calculation is simple, and easily operated and accuracy rate is high.
In an optional embodiment of the present embodiment, between step 102 and step 103, step can also be included 102a：
Whether each time interval in whole time intervals in the X level saltus step that judgement is continuously detected is equal It is right in whole time intervals in the X level saltus step included in the N number of wave sequence formed with default X level saltus step The time interval answered meets same preset relation, if it is, performing the N number of waveform sequence formed according to default X level saltus step The time interval between any two level saltus step in the wave sequence feature of row and X level saltus step being continuously detected The step of transmitting continuous time of one wave sequence of calculating.As shown in Fig. 1 D and 1C, work as N=5, X=4, judge 4 detected Each time interval in whole time intervals (as shown in figure iD) in individual level saltus step whether with default 4 electricity Corresponding time interval meets same preset relation in whole time intervals (as shown in Figure 1 C) in flat saltus step, wherein, together One preset relation is：For example, the time interval between the first level saltus step and second level saltus step that detect is 50ns, Time interval between default first level saltus step and second level saltus step is 100ns, in the level saltus step detected Time interval with the time interval of default corresponding saltus step be 0.5 times of relation；Detect second level detected Time interval between saltus step and the 3rd level saltus step is 50ns, default second level saltus step and the 3rd level saltus step Between time interval be 100ns, the time interval in the level saltus step detected between the time of default corresponding saltus step It is divided into 0.5 times of relation；The W level saltus step detecting is jumped with W+1 (wherein, W is positive integer, and W+1≤X) level The time interval of change, the time interval with default the W level saltus step and the W+1 level saltus step is 0.5 times of relation；Inspection Time interval between the first level saltus step measured and the 3rd level saltus step is 100ns, and default first level is jumped The time interval become between the 3rd level saltus step into 200ns, time interval in the level saltus step detected with it is default The time interval of corresponding saltus step is 0.5 times of relation, that is, the Y level saltus step detected with Y+2 (wherein, Y is just whole Number, and Y+1≤X) level saltus step time interval, and between the time of default the Y level saltus step and the Y+2 level saltus step Every being 0.5 times of relation；By that analogy, when the time interval in all level saltus steps detected and its default corresponding jump The time interval of change is 0.5 times of relation, you can is considered as same preset relation, it may be determined that 5 wave sequences continuously transmitted are 5 wave sequences corresponding to default data frame head.When in whole time intervals in X level saltus step being continuously detected Each time interval whether X level saltus step including in the N number of wave sequence formed with default X level saltus step In whole time intervals in corresponding time interval when meeting same preset relation, can be by X be continuously detected electricity Flat saltus step is defined as data frame head, calculates the transmitting continuous time of a wave sequence after data frame head is determined again, can ensure The accuracy that the transmitting continuous time calculates, improve efficiency of transmission.
