[0032] Embodiments of the present application provide a broadcast station matching identification method for a vehicle terminal, as shown in Figure 2 The method is applied to a vehicle terminal 10, which is in communication connection with a receiving antenna 20 to realize transmission of data information. The vehicle terminal 10 executes a stored software program to realize the above-mentioned broadcast station matching identification method for a vehicle terminal. The receiving antenna 20 is used to receive a digital audio broadcast signal and forward it to a radio chip of the vehicle terminal 10. The vehicle terminal 10 is configured with a display screen for displaying radio program information and a loudspeaker for playing broadcast audio.

[0033] As shown in Figure 1 The method comprises steps S110-S160.

[0034] S110, receiving a digital audio broadcast signal from the receiving antenna, and parsing the digital audio broadcast signal to obtain corresponding configuration information.

[0035] The receiving antenna can receive a digital audio broadcast (DAB, Digital Audio Broadcasting) signal emitted by a broadcast signal tower. The receiving antenna forwards the digital audio broadcast signal to the vehicle terminal. The vehicle terminal parses the digital audio broadcast signal to obtain corresponding configuration information and broadcast audio information. The configuration information is used to record configuration parameters in the digital audio broadcast signal. The broadcast audio information is specific broadcast audio content. Decoding the broadcast information in the digital audio broadcast signal except the configuration information can obtain corresponding broadcast audio information. Playing the broadcast audio information allows the user to hear the broadcast audio program content.

[0036] The configuration information is stored in the form of FIG (Fast Information Channel) data in the digital audio broadcast signal. The digital audio broadcast signal is segmented according to a preset signal format, and the information type corresponding to each paragraph in the signal format is determined. The signal format includes the information type corresponding to the field position in the signal, for example, the information type corresponding to the field position of 1-64 bits in the signal format is configuration information, and the information type corresponding to the field position of the last 32 bits in the signal format is an initial check code.

[0037] S120, determining whether the configuration information matches the pre-stored current configuration information.

[0038] The vehicle terminal stores the configuration information corresponding to the last received digital audio broadcast signal, and the configuration information corresponding to the last received digital audio broadcast signal can be used as the current configuration information. It can be determined whether the current obtained configuration information matches the current configuration information. If they match, it indicates that the radio program information is not updated. If they do not match, it indicates that the radio program information is updated.

[0039] In specific embodiments, step S120 includes a sub-step of extracting a corresponding configuration information identifier from the configuration information, and determining whether the configuration information identifier matches a current information identifier in the current configuration information to determine whether the configuration information matches the current configuration information.

[0040] The configuration information is MCI (Multiplexing configuration information), and a corresponding configuration information identifier (MCI ID) can be extracted from the configuration information. The configuration information identifier is an 8-bit (1 bit) field length.

[0041] Similarly, a corresponding configuration information identifier is extracted from the current configuration information as a current information identifier, and it is further determined whether the configuration information identifier matches the current information identifier. If they match, it is determined that the configuration information matches the current configuration information, and the subsequent step of identifying the broadcast station is not needed. If they do not match, it is determined that the configuration information does not match the current configuration information, and the subsequent step of identifying the broadcast station is immediately performed.

[0042] S130, if the configuration information does not match the current configuration information, obtaining corresponding candidate station information from the digital audio broadcast signal according to the radio program information corresponding to the current configuration information.

[0043] The radio program information corresponding to the current configuration information is used to filter the radio stations included in the digital audio broadcast signal, and the radio stations included in the digital audio broadcast signal that match the radio program information are filtered out, and only the radio stations not included in the radio program information are retained, thereby obtaining candidate radio station information.

[0044] In step S140, whether the candidate radio station information matches the radio program information is determined according to a preset matching rule, and a matching determination result is obtained.

[0045] In step S140, whether the candidate radio station information matches the radio program information is determined according to a preset matching rule, and a matching determination result is obtained.

[0046] In a specific embodiment, step S140 includes the following sub-steps: determining whether the radio station identifier of the candidate radio station information is the same as the radio station identifier of any radio program in the radio program information; if the radio station identifier of the candidate radio station information is the same as the radio station identifier of a radio program, determining whether the region code of the candidate radio station information is the same as the region code of the radio program; if the region code of the candidate radio station information is the same as the region code of the radio program, a matching determination result is obtained; if the radio station identifier or the region code of the candidate radio station information is different from each of the radio programs, a non-matching determination result is obtained.

[0047] The candidate radio station information includes a radio station identifier and a corresponding region code; the radio station identifier can be a service identifier (Service ID), and the region code can be an extended country code (ECC, Extended Country Code). For a radio station identifier in the candidate radio station information, it can be determined whether the radio station identifier is the same as the radio station identifier of any radio program in the radio program information, and it can be determined whether the region code corresponding to the radio station identifier is the same as the region code of the radio program in the radio program information. If the radio station identifier in the candidate radio station information and the corresponding region code are the same as the radio station identifier and the region code of a radio program in the radio program information, it is determined that the candidate radio station information matches the radio program in the radio program information, and a matching determination result is obtained. Only when the radio station identifier and the region code of the candidate radio station information are the same as the radio station identifier and the region code of the same radio program, it is considered that the candidate radio station information matches the radio program. If the radio station identifier in the candidate radio station information is different from the radio station identifier of each radio program in the radio program information, or the region code in the candidate radio station information is different from the region code of each radio program in the radio program information, it is indicated that the candidate radio station information does not match each radio program in the radio program information, and a non-matching determination result is obtained.

[0048] S150, if the matching result is matched, adding the candidate radio information to a standby radio list corresponding to the radio program information.

[0049] If the matching result is matched, it indicates that the candidate radio information is a standby radio station of a radio program in the radio program information, and the candidate radio information is added to a standby radio list corresponding to the radio program information. Each standby radio in the standby radio list is associated with a radio program in the radio program information, and the radio program associated with the standby radio in the radio program information can be used as the associated radio program corresponding to the standby radio. That is, each standby radio is associated with one associated radio program, and one associated radio program can be associated with zero, one or more standby radios.

[0050] In specific embodiments, step S150 includes a sub-step of obtaining corresponding service link information from the candidate radio information, performing signal quality detection on the service link information according to a preset detection rule to obtain a detection result of whether to pass, and adding the candidate radio information to the standby radio list if the detection result is passed.

[0051] Specifically, the corresponding service link information can be obtained from the candidate radio information, and the service link information is extracted from the 0 / 5 type in the fast information channel of the digital audio broadcast signal. The service link information specifically includes target frequency virtual, associated identification information and valid time window information. The target frequency is the frequency value used by the broadcast program corresponding to the candidate radio information, which can be accurate to 1 kHz. The associated identification information is the associated program ID (Linked Service ID), and the valid time window is the time information used to judge the timeliness of the link.

[0052] The signal quality of the service link information is detected according to the detection rule to obtain a detection result of whether to pass. If the signal quality meets the detection condition set in the detection rule, the detection result is passed. If the signal quality does not meet the detection condition set in the detection rule, the detection result is not passed. If the detection result is passed, the candidate radio information is added to the standby radio list. If the detection result is not passed, it indicates that the signal quality corresponding to the candidate radio information is unqualified, and the candidate radio information is not added.

[0053] In specific embodiments, the signal quality detection on the service link information of the candidate radio program according to the preset detection rule comprises: acquiring signal quality information of a corresponding frequency point according to target frequency information in the service link information; judging whether signal strength in the signal quality information is greater than a signal strength threshold in the detection rule; judging whether a carrier-to-noise ratio in the signal quality information is greater than a carrier-to-noise ratio threshold in the detection rule; if the signal strength is greater than the signal strength threshold and the carrier-to-noise ratio is greater than the carrier-to-noise ratio threshold, a passing detection result is obtained; if the signal strength is not greater than the signal strength threshold or the carrier-to-noise ratio is not greater than the carrier-to-noise ratio threshold, a failing detection result is obtained.

[0054] The signal quality information of the corresponding frequency point corresponding to the target frequency information can be acquired according to the target frequency information in the service link information, and the signal quality information includes signal strength and carrier-to-noise ratio. The signal strength can be RSSI (Received Signal Strength Indicator), which is used to represent the received signal strength. RSSI is usually represented in negative dBm (decibel milliwatt) units, and the closer this value is to 0, the stronger the signal is; the carrier-to-noise ratio (CNR) is used to indicate the standard measurement scale of the relationship between the carrier and the carrier noise; a high carrier-to-noise ratio can provide better network reception rate, better network communication quality and better network reliability.

[0055] It can be judged whether the signal strength is greater than the signal strength threshold set in the detection rule, and whether the carrier-to-noise ratio is greater than the carrier-to-noise ratio threshold set in the detection rule. If the signal strength is greater than the signal strength threshold and the carrier-to-noise ratio is greater than the carrier-to-noise ratio threshold, the detection result obtained is passing; if the signal strength is not greater than the signal strength threshold or the carrier-to-noise ratio is not greater than the carrier-to-noise ratio threshold, the detection result obtained is failing.

[0056] In specific embodiments, after the candidate radio information is added to the standby radio list corresponding to the radio program information, the method further comprises: constructing a mapping relationship between the newly added standby radio in the standby radio list and a frequency modulation identification code in the analog broadcast signal.

[0057] After the candidate station information is added to the standby station list, a mapping relationship between the newly added standby station and the FM identification code in the analog broadcast signal can also be constructed. The newly added standby station is a broadcast station corresponding to the candidate station information. The station code (the lower 16 bits of the Service ID) and the area code (the upper 4 bits of the ECC) of the newly added standby station are obtained from the candidate station information, and the station code and the area code are matched with the FM identification code (FM PICode) in the analog broadcast signal. If the station code matches a certain FM identification code and the area code matches the regional coding rule of the FM identification code, the FM station information corresponding to the FM identification code can be obtained and a mapping relationship with the newly added standby station is established. This mapping relationship indicates that the FM station information and the program content played by the newly added standby station (digital broadcast station) are the same.

[0058] S160, if the matching result is not matched, updating the station program information according to the candidate station information.

[0059] If the matching result is not matched, it indicates that the candidate station information is a newly added broadcast station. The station program information can be updated by the candidate station information, so as to increase the new broadcast station program corresponding to the candidate station information in the station program information.

[0060] In specific embodiments, before the updating of the station program information according to the candidate station information, it further includes: judging whether the audio features between the candidate station information and the station program information are matched according to a preset audio feature matching rule, to obtain a corresponding audio feature judgment result; if the audio feature judgment result is matched, returning to execute the step of adding the candidate station information to the standby station list corresponding to the station program information; if the audio feature judgment result is not matched, executing the step of updating the station program information according to the candidate station information.

[0061] To improve the reliability of the subsequent station program information matching, if the matching result is not matched, the audio features between the candidate station information and the station program information can also be judged according to the audio feature matching rule. Specifically, the audio features of the broadcast audio information corresponding to the candidate station information can be obtained, the audio features of the broadcast audio information of each station program in the station program information are further obtained, the audio similarity (such as the cosine similarity value) between the two groups of audio features is calculated, and it is judged whether the audio similarity is not less than the similarity threshold set in the audio feature matching rule.

[0062] If the audio similarity between the candidate radio information and a radio program is greater than the similarity threshold, it indicates that the audio feature similarity between the candidate radio information and the radio program is high, and a matched audio feature judgment result is obtained; if there are multiple radio programs with audio similarity greater than the similarity threshold, the radio program with the highest audio similarity is obtained as the associated radio program. If the audio similarity between the candidate radio information and each radio program is not greater than the similarity threshold, a non-matched audio feature judgment result is obtained. The audio feature can be MFCC (Mel-Frequency Cepstral Coefficients, Mel-frequency cepstral coefficients) feature, which can simulate the perception characteristics of human ears to sound, so as to obtain a voice feature more consistent with the auditory system.

[0063] The broadcast radio matching identification method for the vehicle terminal disclosed in the above embodiments includes: receiving a digital audio broadcast signal from a receiving antenna and parsing configuration information, judging whether the configuration information matches the pre-stored current configuration information, obtaining candidate radio information if they do not match, judging whether the candidate radio information matches the radio program information corresponding to the current configuration information according to the matching rule, and obtaining a matching judgment result; if the matching judgment result is matched, the candidate radio information is added to the standby radio list, and if the matching judgment result is not matched, the radio program information is updated according to the candidate radio information. The broadcast radio matching identification method for the vehicle terminal can identify the broadcast radio through the obtained composite identifier, accurately identify the repeated broadcast radio across regions, and greatly improve the identification efficiency of the broadcast radio.
