It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a schematic flow chart of a method for tracing and acquiring communication data according to an embodiment of the present invention, which is applicable to a situation of tracing and acquiring communication data, and is particularly applicable to a situation of a large communication data chain. The method can be executed by a communication data tracing and collecting device, and the device can be realized in a software/hardware mode. The method can be integrated in a communication data processing server, and specifically comprises the following steps:
s110, it is detected whether the currently received signal exceeds a stored threshold.
In this embodiment, the received signal is stored in a buffer, and may be written in the buffer in a circular write overlay manner. And monitors over time whether the currently received signal exceeds a stored threshold.
Illustratively, the detecting whether the currently received signal exceeds a stored threshold includes: acquiring a data start index and a data end index in a received signal, and determining the data volume according to the data start index and the data end index of the data; and determining whether a storage threshold value is exceeded or not according to the data size. According to the buffered signal, the start index and the end index are determined according to the corresponding identification in the signal. The amount of data is determined from the start index and the end index, and a determination is made whether a storage threshold is exceeded based on the size of the amount of data.
In this embodiment, the above-mentioned manner can be implemented by the following statements:
// data start index public int DataEnd { get; set; }// end of data index public RingBufferManager (int bufferSize) { DataCount ═ 0; DataStart ═ 0; DataEnd ═ 0; buffer ═ new byte [ bufferSize ]; }
And S120, when the storage threshold value is exceeded, transferring the currently received signal into a data buffer storage area for storage, and writing the data buffer storage area into a process and adding the process into a process lock.
In this embodiment, the spectrum display is opened and the analog data channel is opened at the same time, the analog data is stored in a well-defined buffer area, and when the acquisition is not performed, the data in the buffer area is cyclically covered until the acquisition is started, and the data is exported from the buffer area for storage. Specifically, writing data in the buffer may include the following cases:
1) and when the data volume is smaller than the free area of the data buffer storage area, storing the currently received signal into the data buffer storage area.
2) When the data volume is larger than the idle area of the data buffer storage area, determining the coverable area according to the identification bit of the occupied area; the currently received signal is written directly to the coverable area.
3) Acquiring the byte number and the residual byte number of the currently written signal; and when the number of the remaining bytes is larger than that of the remaining idle area, acquiring the data in the processed data counter, and when the number of the data is larger than that of the remaining bytes, clearing the corresponding data.
If there is a blank area in the data buffer area larger than the data amount, the data amount may be determined according to the start and end indexes in the above steps. Signal data can be written directly into the free area.
If there is no empty area in the data buffer, it needs to be checked whether there is an coverable area, which may include the corresponding data that has been stored off-disk. Or data that has been invalidated, etc. Therefore, the corresponding flag bit can be determined according to the data table in the cache region, and the coverable region can be determined according to the flag bit.

And judging whether the residual space can meet the storage requirement according to the byte number of the received signal, and emptying the data when the storage requirement is not met so as to facilitate writing of the data.
The above several ways can be realized by the following codes:
acquiring the currently written byte number { return DataCount; obtaining the number of the remaining bytes { return buffer. Length-DataCount; public void Clear () { DataCount ═ 0; the method comprises the steps of } public void Clear (int count)// clearing data of a specified size { if (count > ═ DataCount)// if the data needing clearing is larger than the existing data size, clearing all { DataCount ═ 0; DataStart ═ 0; DataEnd ═ 0; else { if (DataStart + count >) { buffer.length) { DataStart ═ DataStart + count) } buffer.length; else { DataStart + } count; tatacount-count; { public void write buffer (byte [ ] buffer, Int offset, Int count) { Int32 reserveCount ═ buffer, length-DataCount; if (reserved count)// available space can be used { if (DataEnd + count < buffer.length)// data does not end { array.copy (Buffer, offset, Buffer, DataEnd, count); DataEnd + ═ count; DataCount + ═ count; else// end of data index out of end loop to start system. Int32 overflowindexength ═(DataEnd + count) -buffer. // exceed index length Int32 endpushindextlength, count-overflowindextlength; copy (Buffer, offset, Buffer, DataEnd, endpushindextlength) of data length padded at the end; DataEnd ═ 0; offset + (endpushindenlength); DataCount + (endPushIndexLength); if (overlaflo indexength | ═ 0) { array. -DataEnd + - (overflowindexength; // end index DataCount + ═ overflowindexength;
optionally, the data buffer storage area is 500MB, 1GB and 2 GB. The simulation data of 1 second, 2 seconds and 4 seconds can be cached respectively, the data are continuously covered when the acquisition is not started, and the data are started to be output and stored in files after the acquisition is started. And writing the data buffer memory area into a process and adding the process into a process lock so as to avoid interference caused by other operations on the data buffer memory area and avoid the condition of data inconsistency.
