Drawings
FIG. 1 is a flow chart of a method of multi-station telemetry data one-key clip synthesis.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
Example 1
As shown in fig. 1, a method for one-key clip synthesis of multi-station telemetry data includes the steps of:
1.1 pretreatment
The preprocessing module firstly reads, scans and analyzes the original data of each station to obtain an initial state position word and an initial valid id, a cut-off state position word and a cut-off valid id, and performs data quality evaluation.
The id has the characteristic of two zero clearing, and the id value can appear in three positions. And a status position word is additionally arranged, so that the data positions can be correctly aligned when the files are ordered.
id is a positive number, typically 2 bytes, in the decimal range 0-65535. Overflowing when the +1 count is full, and restarting the +1 count when the +1 count is changed to 0; when the target starts, id is also clear 0. This requires analysis of the data for each segment, locating the initial state position, 0 invalid data, 1 before overflow, 2 after overflow, before start, 3 after start.
Invalid data refers to the fact that no lock has occurred in the data from beginning to end (id three consecutive). It is possible that the data mixed in is not the task at this time, and the frame structure is not right; it is also possible that the frame count position is misplaced; it is also possible that the data quality is too poor, the bit errors are too many, and the data cannot be used.
When the data is changed from out-of-lock to lock, the status position word is +1, and after every occurrence of id return to 0, the status position word is locked again, and the status position word is also +1 (added 2 times at most).
After the file scanning is finished, a state position word needs to be corrected once, if the state position stays at 1, only the data of the dead zone is corrected to 3, and the state position is indicated that the site or the initial id is not in the head zone and t0 is not received; if the data is remained at 3, the data in the head area is overflowed by 0 and is corrected to be 1; if stay at 2, the header data that does not contain overflow 0 is indicated and no correction is needed.
1.2, ordering
The ordering module compares the initial state position word, the initial valid id, the cut-off state position word and the cut-off valid id of each station in sequence. The numerical value is small before.
As the multi-station files participate in the editing synthesis and need to be discharged in sequence, the method is beneficial to the later editing synthesis and improves the efficiency. In principle, the head station starts and ends first.
1.3, clip composition
And the editing and synthesizing module simultaneously opens the data files of the front station and the rear station for reading and comparing, automatically switches the data of each station and edits the complete task data.
The status position words, id, noise values of the two stations are compared in turn. A small value is written to the file. If all the same use of the pre-station data.
And in the comparison process, if the data of one station is finished or the data of the post-station is covered, automatically switching to the data file of the post-station according to the preset condition. I.e. another station becomes a pre-station and a post-station becomes a post-station until all data synthesis is completed.
The step does not change the original file, does not generate an intermediate file, clips the synthesized data according to a preset sequence, and generates a new data file. And automatically reading, scanning and analyzing the new data file, and evaluating the data quality again.
2. Three functional modules
2.1, read valid full frame Module
The module (reading processing module) is called in preprocessing and editing synthesis to scan data, and three functions are included in the module.
2.1.1 full frame ordering
A full frame buffer is opened up, a full frame data is read in, and whether the full frame data is complete or not is checked. If the next full frame data is not read (the following sub-frame addresses are used for each sub-frame address), checking and judging the next full frame data as before; if yes, the loop is exited, the data in the buffer area is full frame data meeting the requirement, and the processing of other application processes is waited.
The basis for checking a complete full frame is: for the inverse code sub-frames, the sync word of each sub-frame is correct; the (sub-frame) sync word of the last sub-frame is the inverse of the sub-frame sync word.
The data of the subframe demodulated by the hardware is stored in the shared memory, and if the signal is interfered, the phenomenon that a plurality of subframes are lost to the demodulated data occurs, and the whole frame needs to be resynchronized.
The number of samples can be increased by using a synchronous word fault tolerance technique, i.e. a technique that properly allows for a small number of errors in the synchronous word. And adding a synchronous word noise value to reflect the number of synchronous word error code bits in the full-frame data. And when the two stations are aligned with the same id, high-quality data is reserved to provide an interpretation basis.
The statistics of each state position interval is carried out, the accumulated noise value (the frame loss is counted according to the error code) is divided by the total number of bits of the synchronous words which should be received in the interval, and the error rate of the interval can be obtained, so that the quality of the received data is indirectly reflected. 0 represents no error.
2.1.2 identifying and rejecting error code frames
Because the computer uses binary, decimal expression has errors, the value of the result 0 of floating point operation is sometimes a very small value, and the judgment of equality between the relative time and the theoretical value can not be triggered ever.
Both error code and frame loss can cause the frame count value to jump upwards to be empty, and the error code frame needs to be removed to retain effective data.
When locking for the first time, it can deduce the corresponding zero, t when id is 0 value under constant code rate 0 When =t-theory. Where theoretical time=id, full frame period, full frame period=code rate/subframe length.
Thus, when compared (t-t 0 ) When=theory (timing coincidence), the error code id and the effective id can be effectively distinguished.
The method is high-quality accurate inspection, and can directly and accurately identify and reject the error code frames for discontinuous frames and heavy frames (such as 1,3, 5 sequences, 3 interference from 2 to 3 or 3 interference from 4) mixed with the error code frames. Disadvantages: clock stabilization is required.
As the accuracy of the time word is 0.1ms, the data show that the error code can be judged when the time sequence difference in the short interval is more than 1 ms.
Thus, in conjunction with the previous analysis conclusion, the timing agreement can be expressed in terms of |relative time-theoretical time| < 0.001.
Assuming that 40 full frames are transmitted downstream per second, the frame period is 0.025s, which is only theoretical, the read data is analyzed, and the time difference between 2 adjacent full frames is used to obtain a true full frame period of 24.7-25.3 ms. The direction of the receiving antenna can be adjusted by testing in a factory building, so that no frame loss and no error code of data are ensured. For example, about ten minutes of saving, the time and id corresponding to the first valid frame are 03:36.5684 11065, the last valid frame corresponds to 14:06.4443 36260. Time interval=11×60+6.4443-36.5684 =629.8759 s, id interval translates into time= (36260-11065) ×0.025= 629.875s.
Analysis: the true full frame period fluctuates by ±0.3ms, and the average full frame rate (36260-11065)/629.8759 = 39.9999428459 full frames per second is slightly slower than the theoretical 40 full frames. The clock indicating the group of data has very slight delay drift, is accumulated slowly by 0.9ms about half a minute, and has very good timing consistency. However, if the accumulation value reaches + -25 ms, it will have + -1 effect on id, so it is reasonable to correct Zhong Piao once + -1 ms.
The delay may be caused by multipath reflection, which is unavoidable.
2.1.3, correction Zhong Piao
Some devices have uneven transmission code rate, which makes it difficult to accurately identify error code frames and requires clock repair. Zhong Piao is not cleared, and the following data is discarded as error frames under the criterion of consistent timing. Relative-theoretical, zhong Piao.
The cancellation Zhong Piao is to subtract Zhong Piao when id is re-locked and then re (twice) scan the data before after the last timing match, with the retrace cell naturally occurring between the two locks. To immobilize the original data, a reference variable t is added Base = -Zhong Piao.
+t when I are opposite Base Theoretical time |<0.001 indicates that Zhong Piao is equal to the theoretical value when corrected and compared.
The method is also applicable to large-area frame loss, re-synchronization after long-time unlocking of code synchronization and time inaccuracy caused by the code synchronization.
After Zhong Piao is eliminated, the condition that the time sequence is consistent is not necessarily error code is not satisfied, if the interference is serious, frequent and large-area frame loss occurs for many times before the occurrence of the triple frame of Zhong Piao can be repaired, so that Zhong Piao is continuously deteriorated, and even if the triple frame occurs later, the last deterioration of Zhong Piao can only be repaired. This requires first rejecting error frames whose id value is outside the flyback cell. This is based on the fact that errors can produce large deviations away from the retrace interval.
Looking at a group of data with error codes and frame loss, the first effective frame corresponds to 03:35.1010 0, last valid frame corresponds to 16:27.1259 33015, time interval=13×60+27.1259-35.101 =772.0249 s, id interval is converted into time 33015×0.025= 825.375s, and time is shortened by 53.3501s compared with theoretical value.
And analyzing the data in the data, aligning when one frame loss occurs at a time, and aligning when more than ten frame losses occur at a time. Large area frame loss causes time inaccuracy.
The invention is equally applicable to any cause of time misalignment.
2.2, write full frame Module
The write full frame module utilizes the characteristic of consistent time sequence, t=t 0 And in +theory, directly correcting the time word in the whole frame data.
The time words of each station sometimes have inaccurate time caused by large-area frame loss, and need to be corrected into a uniform time sequence.
In order to avoid time sequence confusion caused by changing original data in the process of multiple scanning analysis, the invention corrects the time word before writing the file.
2.3 data quality assessment Module
The preprocessing module and the editing and synthesizing module call the module, and the effects before and after editing are intuitively displayed.
The module obtains the initial state position of the original data, and the initial state position needs to be obtained by scanning the file tail for correction. With this scanning opportunity, useful information is simultaneously acquired and counted as a data quality assessment. The editing data can also be visually compared by giving out data quality evaluation through the module.
The method can also display information such as the position of each state, the effective start-stop id, the interval of losing large data more than 30s at one time, the error rate of a target start period, the storage time, the accumulated time of the missing data and the like in the original data or the editing data, and provide basis for optimizing the equipment algorithm by combining the comprehensive analysis of parameters such as the carrier locking state, the signal-to-noise ratio, the azimuth pitch angle and the like of the corresponding time in the equipment log.
And in the quality evaluation, the bit error rate of the whole task data is counted in a segmented mode to be used as the data quality. The frame loss calculates the error code according to the synchronous word error code bit number of each full frame (effective frame and error code frame). The sum of the accumulated error bits should be compared to the total code bits. A threshold may be set to 10 under limited closed loop conditions －6 I.e. 100 gigabits are not allowed with one bit error.
