step S10: constructing a data processing area, a distribution area and a plurality of partition channels which are sequentially connected, wherein the partition channels are correspondingly connected with a plurality of broadcasting ends;
broadcast refers to a news dissemination tool that transmits sound over radio waves or wires. The program is transmitted by radio waves called wireless broadcasting, and the program is transmitted by wires called wired broadcasting. The broadcasting has the advantages of wide objects, rapid transmission, multiple functions and strong infection; the disadvantage is that the hearing is easy and quick, the hearing is orderly, the selection is impossible, and the hearing is difficult when the language is not clear. In this embodiment, broadcasting refers to a public broadcasting system applied to environments such as schools, intelligent buildings, exhibitions, etc., and according to different broadcasting environments and broadcasting contents, different broadcasting audio needs to be transmitted to different broadcasting ends so as to complete fixed-point broadcasting of the broadcasting audio.
And constructing a virtual data processing area, the distribution area and the partition channels, so that the transmission from the broadcast audio to the broadcasting end can be realized.
Step S20: preprocessing broadcast audio through the data processing area to acquire a transmission signal of the broadcast audio, and transmitting the transmission signal to the distribution area;
when the data processing area receives the broadcast audio, the broadcast audio is preprocessed, in general, the broadcast audio is an analog signal, which may affect the playing quality of the broadcast audio due to external noise and the like, and after the processing, the problem can be avoided, and the broadcast audio is converted into the transmission signal, so that the subsequent laying of a foundation for the transmission path of the broadcast audio can be facilitated.
Step S30: identifying the transmission signals in the distribution area so as to distribute the transmission signals to the corresponding partition channels;
when the transmission signal is transmitted to the distribution area, the distribution area identifies the transmission signal, the broadcasting end of the broadcasting audio can be played as required, the transmission signal is correspondingly issued to the partition channel, real-time adjustment of the broadcasting partition is completed, and the real-time partition adjustment can be completed without adjusting a circuit or a circuit through the mutual coordination among the data processing area, the distribution area and the partition channel, so that the broadcasting effect of the broadcasting audio is improved, and an effective partition means is provided.
Step S40: converting and adjusting the transmission signals based on a broadcasting environment through the partition channels to form broadcasting audio, and transmitting the broadcasting audio to the broadcasting end;
when the transmission signal is transmitted into the partition channel, the partition channel transmits the transmission signal to the broadcasting end for broadcasting, and the partition channel is used for identifying the broadcasting environment of the broadcasting end, so that the transmission signal can be regulated to a certain extent, and the broadcasting effect and the hearing feeling of a listener are better.
Referring to fig. 2, a broadcast audio partition control method according to a second embodiment of the present invention includes the following steps:
step S100: according to the number of broadcasting ends, a plurality of partition channels respectively corresponding to the broadcasting ends are established;
it can be understood that, besides presetting a plurality of partition channels, when receiving a start signal, according to the number of broadcasting ends, the partition channels corresponding to the number of the broadcasting ends can be correspondingly generated, by adopting the generation mode, the number of the partition channels generated each time can be the best state, the generation of excessive data is avoided, if some broadcasting ends are in a standby state due to damage, overhaul and the like, verification can also be performed through the number of the partition channels, and the broadcasting ends are in one-to-one correspondence with the partition channels, namely, after the content to be played enters the partition channels, the content can only be transmitted into one corresponding to the broadcasting ends.
Step S101: establishing distribution areas connected with a plurality of partition channels;
step S102: establishing a data processing area connected with the distribution area;
the data processing area is used for preprocessing the received broadcast audio, and the distribution area is used for corresponding the preprocessed broadcast audio to the partition channels, and it can be understood that the data processing area and the distribution area can be preset in advance, and after a plurality of partition channels are generated, a plurality of partition channels can be connected to the distribution area so as to realize the subsequent broadcasting flow.
Step S103: performing analog-to-digital conversion on the broadcast audio in the data processing area to obtain a digital signal;
in general, the broadcast audio is an analog signal, and by converting it into the digital signal, the subsequent partitioning of the broadcast audio can be facilitated.
Step S104: constructing a flow code according to the region to be played, wherein the flow code comprises a channel code and a priority code;
the area to be played of each broadcast audio may be the same or different, and in the same time, a plurality of broadcast audio exists in the data processing area, and the broadcasting end to which each broadcast audio belongs is determined by constructing the flow code, that is, giving a flow attribute to the broadcast audio. Specifically, the streaming codes include channel codes for pointing to the transmission path of the broadcast audio and priority codes for determining the playing order of the broadcast audio, and in the use environment of the public broadcasting system, there are situations where disaster early warning, emergency situations, etc. need to be inserted, and the priority codes provide an effective solution for the situations. When the data processing area gives the streaming codes to the broadcast audio, there may be a case that the same partition channel needs to broadcast the broadcast audio, so the channel codes further include sequential subcodes.
Step S105: splicing the flow codes and the digital signals to form transmission signals, and transmitting the transmission signals to the distribution area;
after the construction of the streaming codes is completed, splicing the streaming codes into the digital signals, namely, endowing the attribute of a section of broadcast audio to form the transmission signals, and after the acquisition of the transmission signals is completed, transmitting the transmission signals to the distribution area for subsequent processing.
Step S106: extracting pipeline codes of a plurality of partition channels in the distribution area;
step S107: comparing whether the pipeline code matches the channel code;
step S108: if the pipeline codes are matched with the channel codes, transmitting the transmission signals into the corresponding partition channels;
after the distribution area is connected with a plurality of partition channels, the distribution area extracts pipeline codes of the partition channels, and it can be understood that the pipeline codes are in one-to-one correspondence with the channel codes, when the transmission signal is transmitted to the distribution area, the distribution area extracts corresponding fields in the transmission signal and compares and matches the corresponding fields with the pipeline codes stored in the distribution area, when the channel codes are matched with the pipeline codes, the broadcasting end to which the broadcasting audio needs to flow can be determined, and the distribution area transmits the transmission signal to the partition channel corresponding to the pipeline codes.
It will be appreciated that if the pipe code does not match the channel code, the transmission signal is rolled back to the data processing region, the data processing region performs a secondary verification on the transmission signal to check whether the flow code in the transmission signal is wrong, if so, the transmission signal is disassembled, a new flow code is newly given to the digital signal, and the subsequent steps are repeated.
Step S109: if two transmission signals need to be transmitted to the same partition channel, comparing the priority codes of the two transmission signals, and retaining the transmission signals with lower priorities in the distribution area.
The priority indicated by the priority code comprises a normal level and an emergency level, when the same broadcasting end encounters emergency content to be inserted, two sections of transmission signals need to be transmitted in the same partition channel, at the moment, the distribution area compares the priority codes, if the two priority codes respectively point to the normal level and the emergency level, the transmission signals with higher priority are preferentially transmitted, namely, the priority codes point to the transmission signals with the emergency level, and the transmission signals with the priority codes pointing to the normal level are reserved in the distribution area to wait for transmission.
When the distribution area needs to transmit two transmission signals to the same partition channel, after the comparison of the priority codes is completed, if the priority of the priority codes of the two transmission signals is the same, that is, the priority codes of the two transmission signals are all of the common level, the channel codes of the two transmission signals are compared, and the transmission sequence of the transmission signals is determined by identifying sequential subcodes of the channel codes.
Step S110: the partition channel acquires the calibrated broadcast pressure by identifying the distance between a listener and the broadcast end;
the broadcasting range that public broadcasting system aimed is comparatively open space, consequently, the listener with the distance of broadcasting the end is the non-distance, if the broadcasting end carries out with invariable acoustic pressure broadcasting the broadcast audio frequency, if the listener is too close to the distance of broadcasting the end, then listen sound is great, lets the listener feel comparatively noisy easily, if the listener with the distance of broadcasting the end is too far away, then listen sound is less, leads to can not hear broadcasting the end, consequently, through in the intra-regional passageway discernment distance, and acquire demarcation broadcasting pressure, can make the broadcasting end is broadcasting with comparatively suitable acoustic pressure between the distance of listener, in order to improve the broadcast effect, and improve listener's perception. Specifically, the calculation formula of the calibrated broadcast pressure is as follows:
B=M+10lgH-20lgD，
wherein B represents calibrated broadcast pressure, M represents the sensitivity of the broadcast end, H represents the rated power of the broadcast end, and D represents the distance between a listener and the broadcast end. It can be appreciated that a sensor may be disposed at the playing end to identify the distance between the listener and the playing end, and after the D value is identified, the calibrated playing pressure may be calculated by the above formula. Because the listener may be multiple people, the distances between the listener and the broadcasting end are not the same, and therefore, the average value of the distance D between the listener and the broadcasting end can be obtained, so that the calibrated sound pressure is obtained.
Step S111: adjusting the transmission signal to the calibrated broadcast pressure to obtain a broadcast signal;
step S112: and performing digital-to-analog conversion on the broadcasting signal to form the broadcasting audio, and transmitting the broadcasting audio to the broadcasting terminal.
It can be understood that a difference exists between the sound pressure of the transmission signal and the calibration sound pressure, after the acquisition of the calibration sound pressure is completed, the broadcast signal is acquired by performing gain or subtraction on the boost of the transmission signal, after the acquisition of the broadcast signal is completed, the broadcast signal is subjected to digital-to-analog conversion, the broadcast audio is converted into an analog signal again, and the analog signal is played through the broadcast end.
