The embodiment of the present invention provides a method for generating setting audio based on scene customization. After receiving the playback data transmitted by at least one audio playback device from each scene, the received playback data is analyzed to obtain each scene According to the analysis results of different audio playback devices, the audio files to be updated for each scene are respectively generated according to the analysis results of different audio playback devices and transmitted to the audio playback devices of each scene for playback. Based on the method provided by the embodiments of the present invention, the audio playback device set in each scene is managed uniformly through the central control system, and the playback data of each audio playback device is managed and analyzed by the central control system, and the audio playback device is determined and issued. The audio file to be updated realizes cloud management and cloud update of each audio playback device, which is more intelligent and flexible than the traditional manual update method.

In actual applications, before the central control system collects each audio playback device of each scene collects its playback data, the audio playback device set in each scene needs to pre-store relevant data for the current audio playback device to play when it is triggered for the first time. Therefore, before the above step S102, it may further include: personalizing the playback audio data of the audio playback device based on the preset scene of each audio playback device, and pre-transmitting the playback audio data to the corresponding audio playback device , Used when each audio playback device is triggered for the first time. The pre-transmitted playback audio data may include preset playback conditions, pre-stored audio files, and/or preset playback strategies of each audio playback device. That is to say, for any audio playback device, the central control system can pre-transmit the audio playback device's preset playback conditions, pre-stored audio files and/or preset playback strategies, and trigger the audio playback device's first time in the current environment. When the playback conditions are preset, the preset playback strategy can be invoked to play the pre-stored audio files.

Optionally, when the central control system customizes pre-stored audio files for each audio playback device, it can be customized based on the scene type of the preset scene of the audio playback device and/or the deployment position of the audio playback device in the preset scene Audio files of audio playback devices. In this embodiment, the preset scene type can be at least one of the following: gas stations, tourist attractions, parks, railway stations, subway stations, expressway service areas, shops, airports and other large public places with multiple different scenes. For audio playback devices set in different scenes, the pre-stored audio files are different. The following are examples of audio playback files set in different scenes.

1. Gas station

If the preset scene is a gas station, it is a personalized advertisement audio file, a public welfare enterprise publicity audio file, and/or an audio file of a promotional activity for the audio playback device.

Generally speaking, the business of gas stations can be divided into two categories: oil products and non-oil products (commodities, car supplies, car washes, etc.). At present, there are three main types of business for gas stations to promote non-oil products: 1. The communication between the fueler and the consumer (within 1 minute) when refueling, the advantage is that the direct and personal subjective play is maximized. The disadvantage is that it cannot be standardized, is not well managed, and fluctuates greatly after the loss of personnel. 2. Record the promotional activities in the store as audio in advance, and broadcast it through the square dance speakers. The speakers need to be charged and recorded daily, and the speakers are required to be played and received at each station every day. 3. Combining the peak seasons and preferential products of different seasons to be placed in the refueling area, creating a visual impact, but it may be dangerous due to random placement.

Based on the solution provided by the embodiment of the present invention, a service structure of multi-audio playback equipment can be provided for gas stations. Two 20-watt outdoor sound columns and a wall-mounted speaker in the store can be installed on both sides of the left and right door of the convenience store of the gas station. Adjust different indoor and outdoor sound intensities, an audio playback device is connected to the central control system to automatically play pre-stored audio files, without manual operation. Based on the solution provided by this embodiment, the central control system can customize the same audio file uniformly and personally for each audio playback device in multiple gas stations under its jurisdiction, and can also customize different types of gas stations or different geographical locations. Audio files. The content of the audio file will be broadcast after approval by the designated department. Specifically, when the audio file is played through the audio playback device, the advertisement audio file or the promotional audio file can be played at a set time (all 4 and 9 minutes of each hour) to meet the business needs of the gas station scene. In addition, you can also play public welfare corporate publicity audio files from 7:30 to 20:30 in the morning, or when a vehicle is detected, for safety promotion.

2. Tourist attractions

If the preset scene is a tourist attraction, a multilingual scenic spot introduction audio file, various scenic spot introduction audio files, public welfare publicity audio files and/or dining location audio files are customized for the audio playback device.

For tourist attractions and parks, in addition to customizing the audio file for the introduction of the scenic spot or park, for any scenic spot, you can also customize the audio file for the introduction of each scenic spot in the scenic area, as well as weather, toilet location, dining location and introduction, opening and closing The description of scenic parks, humanistic knowledge of civilized tourism, multilingual services, etc., through personalized customization for the broadcast of tourist attractions, can improve the user experience while saving human resources compared to the traditional way of using manual guides.

Third, the subway station

If the preset scene is a subway station, an audio file for self-service ticket purchase elements, an audio file for security checks, an audio file for safety prompts, and/or an audio file for outbound navigation are personalized for the audio playback device.

At present, subways are in operation in many cities. It is an underground railway transportation mode established under the high population and dense travel demand of a city. Taking the subway can not only guarantee travel time, but also be efficient and convenient. Generally speaking, subway management is divided into two structures: construction and operation. The operation is divided into one line and a team is established to manage the entire vehicle operation and personnel management at each station. Each station has multiple (such as about 5) job posts. The types of work can apply for cleaning, security, security, ticket sales, etc. In most cases, a subway station is divided into two floors, the hall and platform floor. The hall floor functions as ticket purchase, security check entry and exit, three links. The platform is for getting on and off the train, the transfer station structure is relatively complicated, and the design requirements of the guidance are high.

In the embodiment of the present invention, the central control system can customize the subway broadcasting to design the broadcasting rules and content requirements in a unit of a single station.

The first type is to customize the audio files of self-service ticket purchase elements; that is, install audio playback equipment in the automatic ticketing area. When many people are buying tickets, the audio playback device will sense the passengers, automatically play the ticket purchase elements, and the broadcast content will follow. The richness of ticket purchases and activities want to be updated to achieve the self-service and unified service of ticket purchases.

The second type is to customize the security check audio file and/or the security prompt audio file; install audio playback equipment in the security check area (broadcast can be set to automatically play, sequence play content can also be sensed), subway security check in the morning and evening peaks and holidays , It tests the patience of passengers under security check. For everyone’s safety, it is still necessary for people to do the inspection. The content of this broadcast should be customized to the necessity of security check, introduction of bans and security check is safe for you, me, and other related explanatory content to reduce security. The explanation intensity of the personnel, soothes the emotions and cooperation of the passengers.

The third is to customize the audio file of the outbound tour; that is, before exiting the gates, many people will look at the subway exit guide map to determine the correctness of the selected exit, and install audio playback equipment above the guide map. When standing in the navigation area, the audio playback device will automatically play the content of the navigation map in response to the settings. The broadcast content can introduce the surrounding routes and buildings in more detail. Great convenience for passengers, so that some people with disabilities can listen. Reduce the flow of people at the station hall level and reduce uncertain factors.

The fourth type is to customize audio files for safety prompts; there can be audio playback equipment on the escalators at the entrance and exit of the subway. In the traditional scheme, the only option is to record the audio in advance and place it in the USB flash drive, and then the staff can insert the USB flash drive at the height of the voice prompter to complete the update and broadcast. If a station has 12 escalators, there are at least 12 voice prompts. , You need to climb 12 times and prepare 24 U disks for replacement. Because the update is troublesome, the broadcast audio is never updated after the subways in each city are basically installed. Based on the solution provided in this embodiment, you can set up audio playback equipment, professionally host the voice recording, and remotely update the voice through the central control system. In peak periods, special weather, and holidays, the prompt voice content should be broadcast with the flow structure of the year. Each tourist station should specifically broadcast the guidance needs of tourist services.

The fifth type is to customize audio files for public welfare publicity; that is, to customize broadcasting to serve passengers and comprehensively enhance the cultural atmosphere of the subway. In the two time periods of the opening of the station in the morning and the closing of the station in the evening, the broadcast can be unified to serve the staff, enhance the subway corporate culture and strengthen the guidance of standardized operations.

4. Expressway service area

If the preset scene is the expressway service area, the real-time weather audio files, safe driving publicity audio files and/or surrounding scenic spots introduction audio files are personalized for the audio playback device.

At present, car travel is also a major way for people to travel, especially on holidays, people travel by self-driving, and car customers will refuel in the service area, rest, eat, go to the bathroom, charge, stay, and go to the supermarket. In the embodiment of the present invention, the audio file customized for the expressway service area may be used to serve the people staying in the service area and the staff who operate the service area daily. According to the architecture and functions of the service area, set up broadcast audio playback equipment. The content of the audio file can include: introduction of the service area, high-speed driving precautions, interpretation of fatigue driving symptoms, high-speed introduction of the service area, weather forecast, surrounding allusions, tourist attractions, During the trough period of the flow of people, broadcast service staff broadcast management content such as corporate presentations and civilized pacesetters. The high-speed service area broadcast is divided into a three-level setting broadcast system, the highest level is the broadcast service content and plan set by the provincial high-speed command center. It is based on the first-line service and management of the province's high-speed. The second senior is a high-speed management, with the goal of serving a high-speed for people and vehicles to establish broadcast services and design. Primary management is based on a service area as the structure, and the design of setting broadcast content. The three levels coexist and have different permissions. The expressway service area broadcast is the most intimate and detailed service for high-speed service car passengers.

5. Airport

The airport terminal is also a place with a large flow of people. For a terminal building, it can be equipped with multiple boarding gates, and the flight schedule corresponding to each boarding gate may change frequently every day. Based on the implementation of the present invention The solution provided in the example can deploy audio playback equipment at each gate, and control the audio playback device corresponding to each gate through the central control system to cyclically play the flight information about to start boarding. Compared with the traditional manual operation by airport staff The broadcast method can reduce the work pressure of the airport staff while using loop broadcast to remind passengers to board the plane in time. Similarly, a similar scheme can be adopted for each ticket gate of a railway station, and audio playback equipment is deployed at each ticket gate to play the train number information that is about to start ticket checking at the corresponding ticket gate.

In another optional embodiment of the present invention, when personalizing the playback audio data of the audio playback device, it may further include: acquiring the deployment position of the audio playback device in a preset scene, and identifying a preset threshold of the distance from the audio playback device At least one of the people flow is greater than the reference location of the preset flow of people; the audio file of the audio playback device is personalized for the audio playback device according to the reference location. Specifically, the positional relationship between the reference location and the deployment location of the audio playback device can be identified, and an audio file including the navigation path from the deployment location of the audio playback device to the reference location can be generated.

For example, when the preset scene is a tourist attraction, an audio playback device a is installed at the exit of scenic spot A in the current tourist scenic spot. Based on previous data analysis, it can be known that the exit of scenic spot A is closer to the south gate of the current scenic spot , And through historical data analysis, it is known that tourists passing through the scenic spot A often ask for the route to the south gate of the scenic spot, and more tourists leave the scenic spot through the south gate of the scenic spot. Therefore, based on the solution provided by the embodiment of the present invention, the south gate of the scenic spot can be used as the reference location of the scenic spot A, the walking route from the scenic spot A to the south gate of the scenic spot A can be obtained, and the audio file in the audio playback device a can be personalized based on the walking route. When it is detected that the tourist leaves the scenic spot A from the exit of the scenic spot A, the audio file is played to prompt the tourist to the route from the current location to the south gate of the scenic spot and so on. In addition to the above introduction, the central control system can also personalize other types of audio files for each scene according to different requirements, which is not limited in the present invention.

As mentioned above, the central control system can manage at least one audio playback device. In actual applications, there can be multiple types of scenes, and multiple audio playback devices can be set in each scene. The total audio playback device can be one million or thousands. Ten thousand. Therefore, when receiving the playback data of at least one audio playback device from each scene in the above step S102, it may further include: receiving the playback data from multiple audio playback devices in each scene in batch; wherein, the playback data consists of multiple audio playback devices. The playback device collects and uploads them separately within the specified time period. Further, it may also include: batch receiving millions or tens of millions of audio playback data uploaded by audio playback devices from each scene.

Referring to the above step S104, after receiving the playback data transmitted by the audio playback device, the central control system can analyze the playback data to obtain analysis results of different audio playback devices for each scene. Optionally, it may further include:

S1. For multiple audio playback devices distributed in the same scene, aggregate the uploaded playback data using the scene as an identifier;

S2. Further analyze the multiple playback data in the set: merge the same information that is parsed into common information, and set the different information that is analyzed as non-common information;

S3. Perform data modeling and data analysis on common and non-common information to generate update data packages that can adjust multiple audio playback devices in batches. Optionally, in specific modeling, common information can be defined as quantitative information in data modeling, and non-common information can be defined as variable information in data modeling, for the same batch of millions or tens of millions The audio playback device uses the same common information as quantitative information and different non-common information as variable information to generate new update data packets for different audio playback devices in batches.

In practical applications, when modeling, a deep learning model can be constructed based on neural networks. For multiple audio playback devices distributed in the same scene, after multiple playback data of multiple audio playback devices are collectively summarized, When analyzing the common information and non-common information of multiple playback data, it can be determined that the played audio file is common information, and the setting position of each audio playback device in the preset scene and the number of times the audio file is played are non-common information. After obtaining the above-mentioned common information and non-common information, data modeling and data analysis can be performed based on the audio file as the common information, the location of the audio playback device as the non-common information, and the number of times the audio file has been played, and then the data can be generated. Batch adjust the new update packets of multiple audio playback devices. Optionally, in this embodiment, after modeling and analysis based on common information and non-common information, the traffic information in the preset scene can be obtained, and then based on the traffic information, a new update that can adjust multiple audio playback devices in batches is generated. Data packets and so on.

Taking a subway station as an example of a preset scenario, suppose the subway station has four entrances and exits A, B, C, and D. It may be set up at each entrance and exit, as well as the ticket office and security checkpoint at each entrance. Audio playback equipment, among which the audio playback equipment installed at ports A, B, C, and D will automatically play audio files about safe entry and exit when they sense the presence of a human body. The audio playback files set at the ticket office are sensing When a human body is present, the playback process will automatically play the audio file playback process related to the ticket purchase elements. The audio playback device set at the security checkpoint will automatically play the audio file playback process for safe riding when it senses the presence of a human body. Each audio playback device can collect the triggering times of the playback process of the audio file within a specified time, and at the same time upload the playback times of the audio file, the setting position of the audio playback device and the corresponding audio file as playback data to the central control system.

If the common information is set to X-type data, the non-common information is Y-type data, and the final human flow data is Z-type data, then the central control system can update the audio file's data after receiving the playback data uploaded by each audio playback file. The triggering process is taken as type X data, and the setting position of each audio playback device and the number of playbacks are taken as type Y data, and then type X data and type Y data are integrated for data modeling and data analysis. At the same time, the model of Z=X+Y is adopted. Synthesize the X-type data and the Y-type data and input the Z-type data corresponding to each audio playback device to determine the traffic information of the people passing through each audio playback device.

For audio playback devices with relatively small traffic, you can continue to play the original audio files. For audio playback devices with relatively small traffic, you can replace the audio files with other subway stations or other The ticket office purchases tickets, thereby dispersing the flow of people, and maintaining the safe and orderly operation of the subway while ensuring the safety of passengers. In practical applications, other relevant data can also be used for data modeling and analysis, which will not be repeated here.

In addition to the foregoing, in the embodiment of the present invention, after obtaining the analysis results of different audio playback devices for each scene, the audio files to be updated can be generated for each scene according to the analysis results. For any audio playback device, when the audio file to be updated is generated, it can first determine whether the audio file of the audio playback device needs to be updated according to the playback frequency and duration of the current audio file. Assuming that the playing frequency and duration of the current audio file of the audio playback device are less than a certain value, it can be determined that there is no need to update, and if the playing frequency and duration of the current audio file of the audio playback device are greater than a certain value, it is determined that it needs to be updated.

Further, when it is determined that an update is required according to the playing frequency and duration, it may further include: keeping the scene unchanged, determining that the playing frequency and/or duration needs to be updated; or, determining that the audio file needs to be updated; determining that it needs to be converted in different scenes , Switch from the first scene to the second scene while adjusting the audio file.

In an optional embodiment of the present invention, for any audio playback device, it can also be combined with its geographic location to determine whether the audio file of the audio playback device needs to be updated. For example, audio playback device A, audio playback device B, and audio playback device C are set near two adjacent landmark locations 1 and 2 in the current park. Among them, audio playback device A is closer to landmark location 1, audio The playback device C is closer to the landmark position 2, and the audio playback device B is set between the two. In general, audio playback device A will play relevant introductions about landmark location 1, audio playback device C will play relevant introductions about landmark location 2, and audio playback device B will play audio files for safe and civilized amusement parks. But suppose that audio playback device A detects that there is a small amount of people nearby, and audio playback device B detects that there is a large amount of people nearby. At this time, you can update the audio file of audio playback device B to make it play about the location of the landmark B's related introduction, or audio files that lead people to other locations.

In the embodiment of the present invention, for any audio playback device, determining the flow of people passing through the audio playback device can also be assisted by ultrasonic sensors for statistics. Fig. 2 shows a flowchart of an ultrasonic sensor system according to an embodiment of the present invention. Referring to Fig. 2, it can be seen that the processing process of the entire system can be as follows:

After the system is powered on, the main control chip DSP controls the ultrasonic signal generating module to generate sine wave and square wave. The sine wave is used to transmit ultrasonic signals, and the square wave is used to demodulate the collected Doppler frequency shift signals. After the ultrasonic transmitter probe emits 640KHZ ultrasonic waves into the fluid at a certain angle, the ultrasonic signal excitation module is to amplify the ultrasonic transmitter signal at a certain power, and adjust the impedance to match the ultrasonic transmitter probe to impedance, so that the transmitter probe can work higher efficiency. After the receiving probe receives the fluid-carrying information signal transmitted by the transmitting probe and passing through the pipe wall and the fluid in the pipe, the signal is transmitted to the ultrasonic receiving circuit module, the weak signal is selected and amplified, and then it is low-noise The amplifier amplifies the useful signal twice to make the useful signal reach a certain amplitude, which is convenient for processing in the subsequent circuit. The useful signal after twice amplification enters the ultrasonic signal demodulation module, and is mixed with the square wave signal generated by the waveform generation module to generate the sum frequency signal and the difference frequency signal of the two signals, and the difference frequency signal generated is Doppler signal of the fluid velocity in the pipeline. The demodulated signal is a current signal, so the frequency difference signal needs to be converted from current to voltage, filtered and sent to the analog-to-digital converter (A/D) of TMS32OF2812 for analog-to-digital conversion. The CPU in the TMS320F2812 processes the obtained digital sequence to obtain the frequency offset value, and then calculates the required amount of data according to the parameters, and then stores and transmits these data to facilitate remote monitoring and data storage of flow data. At the same time, the single-chip C8051F500 is operated for key input and OLCD display.

Referring to the above step S108, after the audio files to be updated are generated for each scene, the audio files to be updated can be transmitted to the corresponding audio playback devices of each scene. In this embodiment, the central control system and each scene can be used. The audio playback device of the audio playback device forms a cloud audio transmission architecture, and the central control system uses the cloud audio transmission architecture to correspondingly transmit the audio file to be updated to the audio playback device of each scene. Specifically, the audio file to be updated may be correspondingly transmitted to the corresponding audio playback device in each scene through 4G, 5G and/or WiFi. Of course, in actual applications, other methods may also be used to transmit the audio files to be updated, which is not limited in the present invention.

Based on the same inventive concept, the embodiment of the present invention also provides a setting update audio playback method in scene customization, which is applied to large places with multiple different scenes. At least one audio playback device is set for each type of scene. For audio playback devices, referring to Figure 3, it can be seen that the method may include:

Step S302: When it is detected that the current environment of the current audio playback device satisfies its preset playback conditions, based on the preset playback strategy, call the pre-stored audio files in the local audio file list of the current audio playback device for playback; wherein, The audio file is pre-transmitted by the central control system governing the current audio playback device to the current audio playback device according to the scene type of the preset scene of the current audio playback device and/or the deployment position of the current playback device in the preset scene In the local audio playlist;

Step S304: Collect playback data within a specified time period, and upload the aforementioned playback data to the central control system, and the central control system adjusts the playback strategy of the current audio playback device based on the aforementioned playback data;

Step S306: Receive an update instruction carrying an update data package issued by the central control system, and update relevant data of the current audio playback device based on the update data package.

The embodiment of the present invention provides a method for playing the updated audio based on scene customization. When it is detected that the current environment meets the preset playing conditions of the audio playing device, the current audio playing device can be called based on the preset playing strategy. The pre-stored audio playback files are played, which saves resources and reduces noise pollution while providing users with the information they need. Further, the solution provided in this embodiment can also collect its playback data within a specified time period through the audio playback device and transmit it to the central control system that governs all audio playback devices, and the central control system will then uniformly check the received data. Perform data analysis on the playback data of the audio playback device to intelligently adjust the relevant playback data of the audio playback device, thereby enhancing the effect of information dissemination, and achieving "what is needed is what you need" and "what is what you need is what you need". Push the information they want and deserve attention.

In step S302, it is mentioned that the audio file will be called up and played only when it is detected that the environment where the current audio playback device is currently located meets its preset playback conditions. Optionally, detecting that at least one element in the environment where the current audio playback device is currently located triggers a sensing component in the audio playback device, and/or the current point in time is any pre-stored audio file in the audio file list At a preset playback time point, the sensing component sends out a device activation signal of the audio playback device, and the device activation signal triggers the audio playback process in the audio playback device. Wherein, the types of the sensing components include at least one of the following: infrared sensors, ultrasonic sensors, weight sensors, video cameras, timers, counters, temperature and humidity sensors, carbon dioxide sensors, MIC microphones for recording sound, and commodities MINIPAD display screen for interaction between video and consumers.

In other words, as long as there are any one or more elements in the current environment that can trigger any sensing component in the audio playback device, the sensing component can send a start signal to the audio playback device to which it belongs to trigger the audio playback device Audio playback process. For example, infrared sensors or video cameras triggered by the human body, carbon dioxide sensors triggered by changes in human flow, temperature and humidity sensors, timers triggered by the current time, and so on. To put it simply, when the sensing component of the audio playback device detects the presence of a human body or determines that the audio file currently needs to be played according to the time strategy, the audio file stored in the audio playback device can be called to control the power amplifier module to drive the speaker to play. In addition, in this embodiment, the sound of the current environment can also be collected through the MIC microphone set in the audio playback device, and video files related to the shelf product can be played through the MINIPAD display screen to realize the interaction between the product and the consumer.

In addition, since the audio playback device can be provided with one or more same or different sensing components, when the current audio playback device includes at least one sensing component, different elements in the current environment can trigger different sensing components. Devices, and then different sensing components initiate different device start signals. For different device start signals, it can trigger the same or different audio playback processes in the audio playback device. Different audio playback processes can be different from the audio files played by the audio playback device, or it can be the playback time of each audio file The difference or frequency can be specifically set according to different scene types, which is not limited in the present invention.

Referring to the above step S302, after the current environment triggers the preset playback condition of the current audio playback device to call up the pre-received playback strategy, the corresponding pre-stored audio file can be recalled and played in the local audio playlist according to the preset playback strategy. The pre-stored audio file in this embodiment is pre-transmitted to the current audio by the central control system that governs the current audio playback device according to the scene type of the preset scene of the current audio playback device and/or the deployment position of the current playback device in the preset scene In the local audio playlist of the playback device, the preset scene can be gas stations, tourist attractions, parks, railway stations, subway stations, expressway service areas, airports, shops, bus stations and other large public places with many different scenes . For different preset scenes, different audio files can be customized specifically to customize audio files for people with different needs. For an audio playback device, a playback strategy can be preset to determine the playback time and times of audio files in the local audio playlist. Therefore, further, the above step S302 may include: retrieve audio files pre-stored in the local audio file list of the current audio playback device; play at least one audio file in the audio playlist in a loop, or based on the corresponding audio files in the audio playlist Select the audio file that matches the current time point and play it.
