Abstract
The invention discloses a treatment method for classifying, identifying and decoding short-wave-band digital signals in real time. A broadband scanning receiver scans, intercepts and captures signals with a short-wave frequency band by means of an antenna in real time, and the interception result of the broadband scanning receiver is in the form of a digital signal alarm list. A computer automatically assigns the digital signal alarm list to a narrow-band receiver. After receiving the digital signal alarm list, the narrow-band receiver sequentially monitors alarm digital signals in the digital signal alarm list according to the sequence of the digital signal alarm list, and generates a corresponding intermediate-frequency output signal at each frequency point. A W61 PC decoding board card classifies, identifies and decodes input intermediate-frequency output signals. According to the technical scheme of the invention, for digital signals that are hard to identify in the daily life, the signals can be automatically and quickly searched and captured in real time, and then are integrally classified, identified and decoded. Meanwhile, the identification result and the decoding file of the signals can be stored in real time and can also be searched. Therefore, the working efficiency is improved.
Description
Technical field
The invention belongs to Classification and Identification and the decoding technical field of digital signal, be specifically related to a kind of processing method of shortwave frequency band digital signal being carried out to real-time grading identification, decoding.
Background technology
The expansion of National Radio shortwave monitor net to the work such as monitoring, interference investigation, monitoring information acquisition of shortwave business provides reliable guarantee, each shortwave monitor station needs by searching for spacing wave, intercepting and capturing, measure, analyze, identify, obtain signal transmitter or signal parameter, if desired demodulation obtaining information is carried out to pending signal, supervision is implemented to it.
The workflow of the daily shortwave monitor of typical case and decode procedure is that broadband receiver obtains the primary signal of daily monitoring frequency range by antenna, receiver inside processes primary signal, and the spectrogram of signal in swept frequency range is presented at the software control interface of broadband receiver.According to working experience, monitoring personnel judge which frequency signal is suspicious frequency, need carry out labor, and record these frequencies; Then interface switching, the software control interface of narrow-band receiver inputs suspicious frequency one by one, controls the Received signal strength frequency of narrow-band receiver.Signal after narrow-band receiver down-conversion is connected to decoding deck input, finally uses the control software design that decoding deck is corresponding, the parsing situation of observation signal.
In observation process, staff needs the interface of operation three equipment, broadband receiver control software design, narrow-band receiver control software design and decoding deck control software design.If the control software design of these three equipment is installed on a different computer respectively, in the face of three computers while that daily monitoring being more necessary, these changing interface and equipment operating bring a large amount of repetitive operation can to monitoring personnel.In addition, in order to can round-the-clock monitor signal, staff needs ceaselessly to observe the current spectrogram of broadband receiver, records suspicious frequency, and add in suspicious frequency list, this can make monitoring produce huge workload.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of processing method of shortwave frequency band digital signal being carried out to real-time grading identification, decoding.
For achieving the above object, technical scheme of the present invention is achieved in that
The embodiment of the present invention provides a kind of and carries out real-time grading identification to shortwave frequency band digital signal, the processing method of decoding, this processing method is: computer generates digital signal alarm list according to carrying out to shortwave in-band signal the result that real time scan cuts from broadband scanning radio, described digital signal alarm list is distributed to narrow-band receiver automatically, after described narrow-band receiver receives signal alarm list, successively the digital signal of reporting to the police in signal alarm list is monitored according to the order in described signal alarm list, corresponding IF output signal is generated to each frequency, the IF output signal of W61PC decoding board to input carries out Classification and Identification, decoding, the decoded state of signal is updated to digital signal alarm list by described computer.
In such scheme, after the decoded state of signal is updated to digital signal alarm list by described computer, the method also comprises: continue to decode until successfully decoded, for decoded signal storage in database to the signal of not decoding.
Compared with prior art, beneficial effect of the present invention:
The present invention is directed to the digital signal that daily identification difficulty is larger, the automatic in real time fast search that can realize signal is caught, Classification and Identification and decoding integration, simultaneously can real-time storage to the result of Signal analysis and decoded file, and can inquire about, make daily prison to the monitoring of digital signal by personal monitoring's Mode change be automatic scan monitor and classification decoding integration, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 provides a kind of flow chart of processing method shortwave frequency band digital signal being carried out to real-time grading identification, decoding for the embodiment of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The embodiment of the present invention provides a kind of processing method of shortwave frequency band digital signal being carried out to real-time grading identification, decoding, and as shown in Figure 1, this processing method is realized by following steps:
Step 101: computer generates digital signal alarm list according to carrying out to shortwave in-band signal the result that real time scan cuts from broadband scanning radio.
Concrete, described broadband scanning receiver carries out real time scan intercepting and capturing by antenna to shortwave in-band signal, and the result that described computer is intercepted and captured is a digital signal alarm list.
Frequency information, modulation system, the decoded state of signal is comprised in described digital signal alarm list.
Step 102: described digital signal alarm list is distributed to narrow-band receiver by described computer automatically, after described narrow-band receiver receives signal alarm list, successively the digital signal of reporting to the police in signal alarm list is monitored according to the order in described signal alarm list, corresponding IF output signal is generated to each frequency.
The IF output signal of step 103:W61PC decoding board to input carries out Classification and Identification, decoding.
Step 104: the decoded state of signal is updated to digital signal alarm list by described computer.
Concrete, described computer is according to the decoded result of W61PC decoding board, real-time update is to digital signal alarm list, if a certain signal is successfully decoded, the decoded state of this signal in digital signal alarm list is updated to and decodes, the information of this signal is saved in database simultaneously, otherwise, then the decoded state of this signal in digital signal alarm list is updated to and does not decode, W61PC decoding board continues to decode to it, until successfully decoded again.
In addition, the information of the signal that preservation has been decoded in described database, to carry out inquiring about and reading.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
