[0002] Radio broadcasting, especially shortwave radio broadcasting, has the characteristic of spreading without borders. For radio stations that are not broadcasting from our side but have an impact on us, we call them interested radio stations. In order to effectively deal with these interested radio stations, we need to actively monitor and understand their broadcasting patterns, including broadcasting companies or entities, broadcasting time, frequency, listening effects, program columns and other characteristic information.

[0003] At present, the traditional monitoring method used by the same industry around the world mainly relies on manual monitoring, entering the collected information into a computer to form a broadcast frequency schedule of the radio station of interest. However, this method has a significant flaw: limited by equipment capabilities and manual information processing capabilities, it is unable to keep up with the frequent frequency changes in the broadcast schedule in winter and summer. Therefore, the accuracy of the schedule is limited, and it is basically impossible to summarize the specific column information of the radio station. This leads to a lag in monitoring data and is unable to timely reflect the latest broadcasting rules of the radio station of interest, which seriously affects the efficiency and accuracy of the monitoring work.

[0052] Regular statistics are performed on the program matching list 8 and the audio and index broadcast record data 7 to generate broadcast distribution and content regularity information 9, wherein the program matching list 8 includes information such as program time frequency content.

[0053] Among them, spectrum analysis includes comparing the spectrum data 3 of the overall radio signal with the comprehensive characteristics of spectrum parameters such as power threshold, bandwidth, frequency deviation, etc., detecting the frequency of the broadcast signal, and generating a spectrum detection signal list 11 and digital baseband data 12 of the channel corresponding to the spectrum detection table; channelization processing processes the digitized radio signal 2 into broadcast baseband data 5 of multiple channels through digital down-conversion, and generates cached broadcast baseband data 13 by processing the delayed digitized radio signal 10; audio processing includes analog demodulation and digital demodulation, audio and audio index parameters 6 include modulation, frequency deviation, carrier-to-noise ratio, signal-to-noise ratio and error vector amplitude, and generates broadcast audio 15 and modulation quality index 16 through audio and audio index parameters 6, and obtains broadcast audio and modulation quality index data 14 through broadcast audio 15 and modulation quality index 16;

[0054] Among them, program matching includes extracting audio data 17 from audio and indicator broadcast record data 7, and program matching also includes matching program template data 18 and program schedule 19 to generate a program matching list 8; regularity statistics include three steps of screening, folding and arbitration, screening out program event information of interest 20 from the program matching list 8 and audio and indicator broadcast record data 7, and generating a broadcast event information combination 21 under a certain time and frequency view.

[0055] A device for monitoring the broadcasting regularity of a radio station, comprising:

[0056] Multi-channel broadcast monitoring receiver for receiving radio signals and performing signal conditioning, broadband analog-to-digital conversion, broadcast signal screening, broadcast channelization and audio processing to generate spectrum data3, audio and audio index parameters6;

[0057] An information processing computer, connected to the multi-channel broadcast monitoring receiver, for recording audio, indexing broadcast recording data 7, generating program matching lists 8 and regular statistical broadcast transmission and content regularity information 9;

[0058] Data storage device for storing audio, index broadcast record data 7, program template data 18, broadcast distribution and content regularity information 9;

[0059] The multi-channel broadcast monitoring receiver is used to complete radio signal reception conditioning, broadband analog-to-digital conversion, broadcast signal screening, broadcast channelization and audio processing, and output spectrum data 3, audio and audio index parameters 6 to the information processing computer. The information processing computer is used to complete the recording of audio and index broadcast recording data 7, the matching of program matching lists 8, the regularity statistics of broadcast transmission and content regularity information 9, and generate a broadcast event information combination 21 under a certain time and frequency view through the program event information 20 of interest.

[0060] The following further explanations are required for the above scheme: Figure 1 As shown, the radio waves in the air are received by the antenna, and after impedance matching, filtering, amplification, attenuation and other conditioning, the analog radio signal 1 is transmitted to the broadband analog-to-digital conversion; the broadband analog-to-digital conversion converts the analog signal into a digital radio signal 2, which is sent to the broadcast signal screening and broadcast channelization; the broadcast signal screening screens the broadcast signal from the radio wave through spectrum and modulation analysis, and sends the broadcast signal list 4 to the broadcast channelization; the screened intermediate data products include spectrum data 3 and are sent to the broadcast record at the same time; the broadcast channelization performs channelization processing on the digital radio signal 2 according to the broadcast signal list 4; specifically, it can include A digital down-converter with a buffer delay and 1-10000 channels is used. The digital down-converter of the broadcast signal bandwidth processes the delayed or undelayed digitized radio signal and outputs the channelized broadcast baseband data 5. The number of data channels is determined by the broadcast signal list 4 and the broadcast channelization design capacity. When the capacity is less than the list, the shortage of resources for demand can be compensated by polling and traversing the list. The broadcast baseband data 5 is transmitted to the audio processing, and the audio processing processes it into broadcast audio and audio index parameters 6 and sends them to the broadcast record. The broadcast audio and audio index parameters 6 include audio-related indicators such as audio carrier-to-noise ratio or signal-to-noise ratio.

[0061] Offline processing is performed after the broadcast record, which includes two parts: program matching and regularity statistics. Program matching retrieves audio and index broadcast data 7 of the focus range from the broadcast record, matches it with the program template of the known broadcast information, and outputs a program matching list 8 to regularity statistics. The matching list includes program information, time, frequency, matching confidence and other contents. An audio record can be associated with multiple template matching information. Regularity statistics summarizes the broadcast record data 7 and program matching list 8 such as audio and index of the broadcast record, and forms broadcasting and content regularity information 9 which is saved to the data information carrier through the broadcast record.

[0062] The more complex steps are broken down in detail as follows:

[0063] Broadcast signal filtering Figure 2As shown, the digitized radio signal 2 is fed to the spectrum analysis and digital delay at the same time; the spectrum analysis outputs the spectrum data 3 of the whole radio signal; the data is detected by spectrum morphology to find the frequency that may be the broadcast signal; this detection can be based on the detection of power threshold, or it can be the comprehensive feature detection of multiple spectrum parameters such as power, bandwidth, frequency deviation, etc.; its spectrum detection signal list 11 is sent to the digital down-conversion; the digital down-conversion outputs the digital baseband data 12 of the corresponding channel of each spectrum detection table from the delayed digitized radio signal 10 according to the signal list; these baseband data are subjected to modulation analysis to detect the signal that meets the broadcast modulation characteristics, and form a broadcast signal list 4 output; for amplitude modulation, frequency modulation or digital broadcasting, the modulation quality corresponding to each modulation mode can be used to judge and filter out the broadcast signal, and the non-broadcast signal detected by the spectrum can be discarded; the advantage of this screening is that it fully covers the broadcast frequency band, and can achieve full time and frequency coverage by processing throughput design; at the same time, under the dual screening of spectrum and modulation indicators, it saves the consumption of down-conversion resources and outputs a broadcast signal list with higher accuracy;

[0064] The digital delay in broadcast signal screening can make up for the time difference between spectrum analysis and detection. When the detection list reaches the digital down-conversion, the signal that triggers the detection is still in the digital delay buffer. Figure 3 Omit this digital delay;

[0065] Audio processing such as Figure 4 As shown, the broadcast baseband data 5 is input through a baseband cache to process audio of 1 to 10000 channels; each channel processes a frequency baseband data at the same time, outputs the audio and audio analysis results of one channel; the processing results are output through the cache; this processing can be polled by audio processing at a higher rate to achieve broadcast baseband data that exceeds the number of audio processing channels; when the current and subsequent processing rates can be balanced, the input and output caches can be omitted; the audio processing principle of each channel is as follows Figure 5 , including audio demodulation and modulation quality analysis; for analog broadcasting, analog demodulation is performed, and its modulation quality includes modulation index, frequency deviation, carrier-to-noise ratio, and signal-to-noise ratio; for digital broadcasting, digital demodulation is performed, and its modulation quality includes error vector amplitude, etc.;

[0066] Program matching principle Figure 6As shown, the broadcast record data 7 is input to the program template making and template matching and proofreading steps; wherein the program template making utilizes the broadcast record data of the present invention and external broadcast recordings to extract characteristic audio information of the radio station and program of interest, and combines the information of the radio station, program, announcer, language, country and region, common time period, etc. to make program template data 18, which is saved in the program template library; the program matching software can also import external templates from external data resources into the program template library, form mutual cooperation between monitoring units, and enrich matching templates; the template matching and proofreading software module extracts data of the concerned scope from the broadcast record data, combines the program template library and the external reference program schedule, matches the recorded broadcast audio and data, and outputs a program matching list 8;

[0067] Regular statistical methods such as Figure 7 As shown, it includes three steps of screening, folding and arbitration; the screening step retrieves the program matching list 8 and the broadcast record data 7 according to the multiple dimensions of the program, time, frequency, signal quality, matching confidence, etc. that the user cares about, and screens out the program event information 20 of interest; this information is a large amount of events related to the program of interest distributed at different times and frequencies; by folding, the event information 20 is projected to the space that the user wants to observe according to time or frequency, forming a broadcast event information combination 21 under a certain time and frequency view; as shown in FIG. Fig.11 As shown in the table in, for example, each week can be folded in time, and the programs of the same day and the same time period in a week are accumulated and counted together to form an operation table of a week with different frequencies; each 24 hours of each day can also be folded together, and the events of the same time on different days are accumulated together to form an operation table of 24 hours of a day with different frequencies; when there are more than one event in a grid of the above table and the event information is different, arbitration is required; for example, in a 24-hour operation table, two different program matching events appear at a certain frequency and a certain time period; different arbitration strategies can be selected to make the output reasonable; arbitration strategies include retaining the majority according to the number of similar events; or filtering according to the matching confidence threshold; or listing different types of events according to finer segmentation; finally, regular statistics output a variety of program regularity views specified by users, and these broadcast and content regularity information 9 are saved to the computer broadcast record;

[0068] in Fig.11 It shows a typical broadcasting schedule table. The table columns represent time periods, with a time period of 15 minutes from 0:00 to 23:45 every day. Each row of the table represents a broadcasting frequency or radio station. When a frequency may be occupied by multiple radio stations, the frequency is divided into multiple rows for display. When a radio station has different program columns on different days of the week, the table row is further divided into multiple rows for display. The program information is represented by the program name plus the days of the week in brackets, where 1-6 represents Monday to Saturday, and 7 represents Sunday.

[0069] In addition, it is necessary to explain that for a device that monitors the broadcasting rules of a radio station, Figure 8 As shown, the broadcasting regularity monitoring of the present invention can be realized; a multi-channel broadcasting monitoring receiver is connected to an information processing computer via high-speed data; wherein the multi-channel broadcasting monitoring receiver completes radio signal reception conditioning, broadband analog-to-digital conversion, broadcasting signal screening, broadcasting channelization and audio processing; the receiver outputs spectrum data 3, audio and audio index parameters 6 to the information processing computer; the information processing computer completes broadcasting recording, program matching and regularity statistics;

[0070] Since the data connection can be a high-speed Ethernet or a dedicated data transmission component, the above-mentioned audio processing, broadcast signal screening, and broadcast channelization work can be partially or completely moved to the information processing computer for implementation;

[0071] The information processing computer can be a regular computer or a server, and a GPU or FPGA can be added to improve the information processing capability;

[0072] A computer board-type multi-channel broadcast monitoring receiver can also be used, connected to an information processing computer through a computer bus slot, so that it appears in appearance and topology as a dedicated device that completes all functions;

[0073] Information processing computers usually need to be equipped with a large storage space; the storage space can be realized through a built-in hard disk or an external storage medium or a network storage server.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
