Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
The first embodiment is as follows:
referring to fig. 1, the ip network broadcast cloud system includes a processing terminal 1100, a point distribution device 1200, and a plurality of playback terminals 1300, where the processing terminal 1100 and the playback terminals 1300 are communicatively connected.
The point arranging device 1200 is specifically configured to:
step one, a village coordinate system corresponding to the remote village is constructed.
Specifically, a point in a remote village is selected as a base point of the village coordinate system, and two straight lines perpendicular to each other and passing through the base point are selected as a horizontal axis and a vertical axis of the village coordinate system, so that the village coordinate system is constructed.
After the village coordinate system is constructed, a plurality of edge coordinates corresponding to a plurality of edge points of a remote village in the village coordinate system are determined by using measuring equipment such as a total station or a distance meter, and a village area used for indicating the occupied area range of the remote village in the village coordinate system is obtained according to the plurality of obtained edge coordinates.
And step two, acquiring the sound propagation area of the playing terminal 1300.
Specifically, the sound propagation radius of the playback terminal 1300 is calculated according to the sound attenuation formula.
The sound attenuation formula may be:
where w is used to indicate the initial position of the sound source;
p is used to indicate the position of a point near the sound source;
Wherein the divergence attenuation value
The calculation formula of (c) may be:
where r is used to indicate the separation distance between points w and p in meters.
Suppose 30dB is the minimum decibel that a person in a remote village can hear, and 70dB of sound is emitted from the sound source, while the order of the person is changed
The value is 3dB, the sound transmission radius satisfies the formula
。
In practical applications, the sound propagation radius may be obtained by a simple estimation method based on: assuming that the decibel value at 1 meter from the sound source is A, the sound source is located at a distance
Decibel values in meters are A-6n (n is a natural number greater than 0).
Then according to the sound transmission radius, utilizing the area calculation formula of the circumference
A sound propagation area S is obtained, where r is used to indicate the sound propagation radius.
And thirdly, generating a plurality of stationing coordinates according to the village coordinate system and the sound transmission area.
The stationing coordinates are used for indicating the installation position of the playing terminal 1300 in the remote village.
Specifically, the layout point positions of the playing terminals 1300 in the remote village are calculated according to the optimization algorithm, so that the layout of the playing terminals 1300 with the least number in the village coordinate system is completed, a plurality of sound propagation areas corresponding to the plurality of the arranged playing terminals 1300 can cover the village area, and a result set comprising a plurality of layout coordinates is correspondingly obtained.
It should be noted that, in practical application, the optimization algorithm may be any one of a genetic algorithm, a simulated annealing algorithm, a hill climbing algorithm, and a particle swarm algorithm, and the specific optimization algorithm is not limited in the embodiment of the present application.
After the corresponding playing terminal 1300 is installed in the remote village according to the plurality of stationing coordinates, the corresponding processing terminal 1100 is installed according to the actual requirement of the remote village, and then the processing terminal 1100 receives the audio signal to be transmitted and transcodes the audio signal into a digital signal.
The playing terminal 1300 receives the digital signal transmitted by the processing terminal 1100, decodes the digital signal into an audio signal, and plays the audio signal.
Specifically, the broadcast terminal 1300 at least includes a decoding module, a broadcasting module, and a self-checking module.
The decoding module is mainly used for decoding the digital signal into the audio signal.
The broadcast module is mainly used for playing the audio signal output by the decoding module.
The self-checking module is configured to monitor whether the operation state of the decoding module/broadcast module is abnormal, and if so, feed back fault information to the processing terminal 1100, where the fault information includes a distribution coordinate of the broadcast terminal 1300 corresponding to the self-checking module.
When people in remote villages use the ip network broadcast cloud system, people transmit audio signals required to be played to the processing terminal 1100 through external equipment, the audio signals are transcoded by the processing terminal 1100 and then are converted into digital signals capable of being wirelessly transmitted, the digital signals are transmitted to the playing terminals 1300 which are located in remote places through communication connection between the processing terminal 1100 and the playing terminals 1300 which are distributed in the remote places, and the digital signals are converted into original audio signals again through decoding processing of the digital signals by the playing terminals 1300, so that the playing terminals 1300 can play the audio signals.
In the transmission process of the audio signal, the audio signal is wirelessly transmitted between the processing terminal 1100 and the playing terminal 1300 in the form of a digital signal, so that the space limitation of the original broadcasting system during wired transmission can be broken through, so that the tedious work of temporarily setting up a wired communication line can be avoided when people in remote villages carry out meetings or festive activities, and the audio signal required to be played can be transmitted to the processing terminal 1100 by means of the external equipment after communication connection is established with the processing terminal 1100 only through the external equipment, thereby greatly facilitating the use of the broadcasting system by the people in the remote villages.
It should be noted that, in practical applications, the external device may be a smart phone or a tablet computer, and the communication connection between the playback terminal 1300 and the processing terminal 1100 may be a 4G connection or a 5G connection, and the specific communication connection between the playback terminal 1300 and the processing terminal 1100 is not limited in this embodiment of the application.
In addition, the purpose of setting the self-checking module in the playing terminal 1300 is to find and feed back fault information in the playing terminal 1300 in time, so that people in a remote village can locate the actual position of the playing terminal 1300 with the fault according to the stationing coordinates carried by the fault information, and go to the actual position in time to maintain the playing terminal 1300 with the fault, thereby reducing adverse effects of the playing terminal 1300 with the fault on the people in the remote village.
Further, in order to prevent people in remote villages from missing messages carried in the audio signal when the broadcast terminal 1300 is in a fault, the processing terminal 1100 is further provided with a monitoring module.
The monitoring module is mainly used for receiving fault information sent by the self-checking module and generating cache information according to the fault information, wherein the cache information is used for indicating a digital signal sent by the fault information.
The specific generation process of the cache information may be:
after receiving the failure information, the monitoring module correspondingly generates a virtual terminal for replacing the failed playback terminal 1300, and receives and stores the digital signal received by the failed playback terminal 1300 via the virtual terminal, so as to obtain the cache information.
When the failed broadcasting terminal 1300 completes the repair of the failure, the failed broadcasting terminal 1300 will send a reconnection signal to the processing terminal 1100.
The processing terminal 1100 reestablishes the communication connection with the playback terminal 1300 according to the reconnection signal; after the communication connection between the processing terminal 1100 and the playing terminal 1300 is established, the monitoring module in the processing terminal 1100 transmits the cache information to the playing terminal 1300 after the fault repair is completed according to the reconnection signal, so that the information carried by the audio signal is not leaked by people in remote villages during the fault and maintenance process of the playing terminal 1300.
Further, in practical applications, since the signal strength of the wireless transmission gradually decreases with increasing distance, for the ip network broadcast cloud system disposed in a remote village, because the distance between a part of the broadcast terminals 1300 and the processing terminal 1100 is relatively long, the digital signal received by the broadcast terminal 1300 which is relatively long from the processing terminal 1100 fluctuates, which adversely affects the listening experience of people in the remote village and interferes with the transmission of the information in the audio signal.
In order to solve the problem that the digital signal fluctuates with the increase of the distance, a transmission module is correspondingly arranged in the playback terminal 1300.
The transmission module is mainly used for transmitting the received digital signal to other adjacent broadcast terminals 1300.
The specific application process of the transmission module is as follows:
the cast terminals 1300 are classified according to the distance between the cast terminal 1300 and the processing terminal 1100.
The digital signal is transmitted to the classified broadcasting terminals 1300 according to a preset propagation rule.
Assume that the actual distance between the processing terminal 1100 and the first playback terminal 1300 is 1000 meters;
the actual distance between the processing terminal 1100 and the second playback terminal 1300 is 1500 meters;
the actual distance between the processing terminal 1100 and the third playback terminal 1300 is 2500 meters;
let the classification rule be:
if the actual distance between the processing terminal 1100 and the playback terminal 1300 is within (0, 1000) (unit is meter), the playback terminal 1300 is marked as a type of playback end.
If the actual distance between the processing terminal 1100 and the playback terminal 1300 is within (1000, 2000) (unit is meter), the playback terminal 1300 is marked as a class ii playback terminal.
If the actual distance between the processing terminal 1100 and the playback terminal 1300 is within (2000, 3000) (in meters), the playback terminal 1300 is marked as a three-class playback terminal.
According to the classification rules, the following can be obtained:
the first playback terminal 1300 is a type of playback terminal;
the second playback terminal 1300 is a class ii playback terminal;
the third playback terminal 1300 is a three-class playback terminal.
Meanwhile, the propagation rule is assumed to be:
if a certain playback terminal 1300 is a type of playback terminal, the processing terminal 1100 establishes a communication connection with the playback terminal to complete transmission of the digital signal.
If a certain playing terminal 1300 is a class two playing segment, the transmission of digital signals is completed by the playing segment of the class one adjacent to the playing terminal.
If a certain playing terminal 1300 is a playing segment of three types, the transmission of digital signals is completed by the playing segment of two types adjacent to the playing terminal.
According to the propagation rule, the audio signal to be transmitted in the present example is transmitted through a process terminal 1100 that receives and transcodes the audio signal to generate a digital signal corresponding to the audio signal, and then the digital signal is transmitted from the process terminal 1100 to the first playback terminal 1300, and when the first playback terminal 1300 receives and decodes the digital signal, the first playback terminal 1300 also transmits the digital signal to the second playback terminal 1300, and similarly, when the second playback terminal 1300 receives and decodes the digital signal, the second playback terminal 1300 also transmits the digital signal to the third playback terminal 1300.
Through the step-by-step transmission mode, the digital signals can be stably and accurately transmitted to each playing terminal 1300 in the ip network broadcast cloud system, so that the condition that the digital signals fluctuate along with the increase of the distance is avoided, and people in remote villages can enjoy better listening experience.
Further, the playing terminal 1300 is further provided with an interfering sound sampling module and a volume adjusting module which are connected to each other.
The interference sound sampling module is configured to collect interference sound information around the playback terminal 1300.
The volume adjusting module is used for adjusting the volume of the audio signal during playing according to the interference sound information.
Specifically, the volume adjusting process may be:
and adjusting the volume when the audio signal is played according to the interference sound information and the volume adjusting formula.
The volume adjustment formula is as follows:
in the formula (I), the compound is shown in the specification,
the volume display device is used for indicating the initial volume of the audio information played by the playing terminal 1300, and the unit is decibel;
Since the human ear has a masking effect, i.e. when one sound is 10 db above another, the smaller sound is difficult to hear and understand by humans due to masking. Based on this, by collecting the interference sound around the playing terminal 1300 and correspondingly increasing the volume of the audio signal played by the playing terminal 1300 according to the interference sound, the interference of the interference sound to the playing terminal 1300 during use is reduced, and people in remote villages can obtain better listening experience.
In practical applications, the above description is provided
May be a natural number not less than 60, and the embodiments of the present application are specific
The numerical values are not limited.
Furthermore, the ip network broadcast cloud system further comprises a noise reduction device.
The noise reduction apparatus is specifically configured to apply a noise reduction algorithm to perform noise reduction processing on the audio signal before the processing terminal 1100 receives the audio signal, so that the processing terminal 1100 can obtain the audio signal after the noise reduction processing.
The noise reduction algorithm is utilized to clear partial noise mixed in the audio signal in the sound receiving process, so that the audio signal can keep good tone quality, and the playing terminal 1300 can bring good listening experience to people in remote villages when playing the audio signal.
It should be noted that, in practical applications, the noise reduction algorithm may be one of an adaptive filter method, a spectral subtraction method, or a wiener filtering method, and the embodiment of the present application does not limit a specific noise reduction algorithm.
