Description

[0001] This application is a divisional application of the invention patent application filed on April 30, 2024, with the invention name “Simultaneous interpretation method, device, equipment and medium based on indoor visible light communication” and application number 202410541984.8. Technical Field

[0002] The present invention relates to the field of light-carrying information communication technology, and in particular to a regional branching method, device, equipment and medium for LED light-carrying information transmission. Background Art

[0003] Indoor visible light communication (VLC) is a communication technology that uses visible light bands for data transmission. VLC uses a light source (such as an LED light) to emit modulated light signals, which are received and demodulated by a light detector (such as a photodiode) to achieve information transmission. Since the visible light band is far away from the traditional radio spectrum, VLC has the advantages of high bandwidth, low interference, and enhanced privacy.

[0004] As a real-time language translation service, simultaneous interpretation plays an important role in international conferences, multilingual events and other occasions. With the increasing frequency of international communication, the demand for simultaneous interpretation systems has also increased. Traditional simultaneous interpretation systems usually rely on radio frequency or infrared transmission technology, but these technologies are susceptible to interference and have frequency congestion problems in high-density usage scenarios. VLC-based simultaneous interpretation systems utilize spectrum resources to provide more stable, efficient and secure services, especially in indoor environments where information security needs to be guaranteed and electromagnetic interference needs to be reduced.

[0005] Currently, for example, the patent with authorization announcement number CN108599844B discloses a simultaneous interpretation device based on visible light communication technology and its working method, which uses LDPC coding and PPM modulation methods. PPM relies on the time position of the pulse to encode information, which requires very precise time synchronization between the receiver and the transmitter. Inaccurate time synchronization may lead to data decoding errors, and each additional language requires a unique time coding mode to be added to the PPM modulation. As the number of languages ​​increases, it becomes more complicated to maintain the uniqueness and distinguishability of each pulse.

[0006] In the prior art, the simultaneous interpretation method using indoor visible light communication modulates audio data of different languages ​​onto different optical frequency bands and projects these modulated lights throughout the conference venue. However, this integrated design not only causes mutual interference between frequency bands, but also affects the signal quality at the receiving end, affecting the accuracy of the translation and the audience's experience.

[0064] Example 1

[0065] See also Figure 1 In a first aspect, an embodiment of the present invention provides a simultaneous interpretation method based on indoor visible light communication, the method comprising:

[0066] For at least one participant wearing a light-carrying receiver:

[0067] S1. Acquire the location information of each participant in the indoor conference place according to the first optical signal received by the optical information receiver of each participant;

[0068] Specifically, first, the light source in the system will emit a first light signal, which contains specific coded information and is used in the subsequent positioning process. The participants in the conference venue are equipped with a light-carrying information receiver, which includes a photosensitive diode or a light sensor, etc. The light-carrying information receiver can detect and receive the first light signal emitted by the light source, and measure and analyze various parameters of the signal, such as signal strength, arrival angle and arrival time, etc. Based on the parameters of the received first light signal, the specific position of each receiver, that is, the position of each participant, is calculated through a positioning algorithm. The positioning algorithm includes but is not limited to a time difference positioning algorithm and a triangulation positioning algorithm, etc. The above positioning algorithms are all existing technologies and will not be repeated here.

[0069] Through this step, the system can obtain the precise location information of each participant, which is crucial for achieving efficient simultaneous interpretation. Accurate location information can provide personalized services for each participant, such as sending translations in a specific language to their location. Accurate positioning information can also help the system manage resources more effectively, such as accurately controlling the direction and intensity of light sources to reduce energy waste.

[0070] As an optional embodiment of the present invention, the step of acquiring the position information of each participant in the indoor conference place according to the first optical signal received by the optical information receiver of each participant includes:

[0071] S11. Control the light source to send the first optical signal, wherein the first optical signal has a first communication carrier frequency;

[0072] In this step, the light source is controlled to send a specific first light signal, which carries a first communication carrier frequency, which is a specific frequency used to help the receiver distinguish this signal from other possible light sources such as ambient light. The use of a specific carrier frequency ensures that the receiver can accurately identify the signal used for positioning and reduce interference from ambient light.

[0073] S12, obtaining actual signal parameters of each of the optical information receivers receiving the first optical signal, wherein the actual signal parameters include: signal strength, arrival angle, and arrival time difference;

[0074] Specifically, after receiving the first optical signal, the receiver measures actual signal parameters of the first optical signal, wherein the actual signal parameters include signal strength, angle of arrival and time difference of arrival. The signal strength indicates the strength or intensity level of the received optical signal, the angle of arrival indicates the angle at which the optical signal arrives at the receiver, and the time difference of arrival is the time difference when different optical sensor units of the receiver receive the same signal. These parameters provide key data for calculating the precise position of each participant. By comprehensively analyzing these parameters, the positioning sensitivity and accuracy of the system can be greatly improved.

[0075] S13. Acquire location information of each of the conference participants according to the actual signal parameters.

[0076] Based on the signal parameters collected in step S12, a specific algorithm is used to calculate the specific location of each participant. The specific algorithm includes a triangulation positioning method, a positioning method based on signal strength, or a positioning method based on arrival time difference, etc., to accurately determine the location of each participant in the conference venue, laying the foundation for providing customized simultaneous interpretation services;

[0077] S2. Obtain the language requirement of each participant, and bind the location information of each participant with the language requirement;

[0078] In this step, the language requirements of each participant are obtained. This can be done before the meeting through a registration form, a mobile electronic device (such as a smartphone application), or on-site selection. The system binds the location information of each participant collected with their language requirements. This means that the system records the location of each participant and the language they wish to receive;

[0079] Specifically, the language requirement of each participant can be obtained by selecting on the display interface of the receiver, and the display interface will display multiple language options. In a specific embodiment, before the language selection is made on the display interface of the receiver, it also includes: establishing a communication connection with the mobile electronic device of the participant, obtaining the system default language of the mobile electronic device, and first selecting the corresponding language option according to the system default language for display on the display interface; the user can independently select the required language to ensure that each participant can receive the translation content they need, and by obtaining the default language of the device, the system can pre-identify and recommend the user's possible language requirements, thereby simplifying the selection process and improving the user experience.

[0080] S3, performing coding and modulation processing on the audio data corresponding to each of the language requirements to obtain a plurality of second optical signals, wherein the communication carrier frequencies of the second optical signals are different;

[0081] Specifically, first, the audio data required for each language is digitally encoded. This includes converting the original analog audio signal into a digital format, and then performing appropriate compression and optimization processing for efficient transmission. Subsequently, the encoded audio data is modulated. Modulation is a process of loading information, i.e., audio data, onto a carrier signal. Audio data of different languages ​​are modulated onto different communication carrier frequencies in order to distinguish different languages ​​during transmission. The modulated data is converted into an optical signal, the so-called second optical signal, for transmission through an indoor visible light communication system.

[0082] As an optional embodiment of the present invention, the step of performing coding and modulation processing on the audio data corresponding to each of the language requirements to obtain a plurality of second optical signals includes:

[0083] S31, obtaining real-time ambient light data in a visible light communication environment;

[0084] Use light sensors to collect real-time ambient light data of the current environment. The real-time ambient light data includes ambient light intensity and spectral distribution. These data provide important information about the current ambient light conditions and help optimize the subsequent frequency allocation and modulation process.

[0085] S32, analyzing the ambient spectral characteristics in the real-time ambient lighting data according to the real-time ambient lighting data and the spectral perception algorithm, and outputting a communication optical frequency interval matching the ambient spectral characteristics;

[0086] In this step, a spectral perception algorithm is used to analyze real-time ambient lighting data to identify the optical frequency range that is most suitable for communication. The spectral perception algorithm is used to analyze the ambient spectral characteristics to determine the optimal communication frequency. By selecting the frequency range that best suits the current environment, ambient light interference is reduced and the quality and stability of signal transmission are improved.

[0087] Specifically, the spectrum perception algorithm is based on the principle of spectral analysis, that is, identifying different light sources and their characteristics by analyzing the spectral composition of ambient light. The light in the environment may include natural light (such as sunlight), artificial light (such as indoor lighting), and other light sources, each of which has its own unique spectral characteristics. By understanding the ambient spectrum, the communication frequency can be selected to minimize overlap with ambient light, reduce interference, and improve signal quality.

[0088] S33, allocating a number of candidate communication frequencies in the communication optical frequency interval for the target translation audio data corresponding to each of the language requirements;

[0089] In this step, a number of alternative communication frequencies are allocated to different languages ​​within the determined communication optical frequency range to ensure that each language has an appropriate frequency available and reduce interference between different frequencies;

[0090] Specifically, within the determined communication optical frequency range, a number of alternative communication frequencies are allocated for each language requirement. This may be based on various factors, such as the number of languages, the priority of each language, etc. When allocating, consider avoiding excessive proximity between frequency points to reduce mutual interference. For example, avoid setting the alternative frequencies too close to prevent signal confusion between two languages.

[0091] For example, but not limitation, the VLC system in indoor conference venues needs to support simultaneous interpretation in four languages: English, French, Spanish, and German. After spectral perception algorithm analysis, the system determines that the frequency range of 650nm to 750nm is most suitable for communication. The system may set an alternative frequency point at 650nm, 675nm, 700nm, and 725nm respectively, or set multiple alternative frequencies for one language. In order to reduce mutual interference between different languages, a preset interval is reserved between the alternative frequencies of adjacent languages. The preset interval is determined according to the communication optical frequency range and the number of language requirements, and no specific restrictions are made here.

[0092] S34, acquiring a signal-to-noise ratio of each candidate communication frequency according to each candidate communication frequency and the real-time ambient light data;

[0093] The signal-to-noise ratio (SNR) is calculated for each candidate frequency to evaluate its communication quality. The signal-to-noise ratio (SNR) is an indicator of signal quality, the ratio of signal strength to background noise. Frequencies with high signal-to-noise ratios will provide clearer and more stable communications.

[0094] S35, selecting the candidate communication frequency with the highest signal-to-noise ratio as the target communication frequency among the candidate communication frequencies corresponding to each target translated audio data;

[0095] The frequency with the highest signal-to-noise ratio is selected from the alternative frequencies as the target communication frequency for each language, ensuring the optimization of the communication quality for each language.

[0096] S36, according to the target communication frequency of each target translated audio data, obtaining a preset modulation rule or a preset coding rule corresponding to the target communication frequency, wherein the preset modulation rule includes a BPSK modulation method, a PAM modulation method, a QAM modulation method, and a CAP modulation method, and the preset coding rule includes: an NRZ coding method, an 8B / 10B coding method, a Turbo coding method and / or a differential Manchester coding method;

[0097] According to the selected communication frequency, the corresponding modulation and coding method is selected. Specifically, if the spectrum type of the target communication frequency is red light, the coding strategy is to use NRZ coding, and the modulation strategy is to use BPSK modulation; NRZ coding is used to convert digital data into high and low levels of optical signals, while BPSK modulation allows binary modulation in phase, which can achieve stable data transmission in red optical communication and improve the signal's anti-interference ability to adapt to different environmental conditions.

[0098] If the spectrum type of the target communication frequency is green light, differential Manchester coding will be selected as the coding strategy, and the PAM modulation strategy will help to achieve high-quality data transmission in green optical communication. Differential Manchester coding is used to provide clock synchronization of data, and the PAM modulation method uses different light intensity levels to represent data, thereby improving the reliability of data transmission. This combination helps to achieve higher transmission stability in green optical communication and reduce data transmission error rate;

[0099] If the spectrum type of the target communication frequency is blue light, select 8B / 10B line coding as the coding strategy and QAM modulation strategy, which is very effective for blue light communication. 8B / 10B coding is a data coding method used to provide data reliability and synchronization. At the same time, QAM modulation combines amplitude and phase modulation, allowing more data to be transmitted within a limited bandwidth. This combination of strategies helps to achieve high-speed data transmission in blue light communication and reduce the risk of signal distortion;

[0100] If the spectral type of the target communication frequency is white light, selecting Turbo coding as the coding strategy and CAP modulation strategy can help achieve high fault tolerance and high-speed transmission in white light communication. Turbo coding is a powerful error correction coding method that can reduce the error rate in data transmission, while CAP modulation combines amplitude and phase modulation and is suitable for high-speed visible light communication. This combination of strategies helps achieve high performance and reliable data transmission in white light communication.

[0101] S37. According to the target communication frequency and the corresponding preset modulation rule and preset coding rule, each of the target translated audio data is encoded and modulated to obtain a plurality of second optical signals with different communication carrier frequencies.

[0102] The audio data of each language is processed using a selected modulation and coding method to obtain a second optical signal for transmission, ensuring efficient and accurate data transmission. The signal of each language is optimized to adapt to specific communication frequencies and environmental conditions. Through these steps, the embodiment of the present invention can provide the most optimized communication frequency selection and signal processing solutions for different languages ​​under different environmental conditions, thereby improving the overall performance and user experience of the simultaneous interpretation system.

[0103] S4. Divide the indoor conference place into several areas according to the location information and the language requirement, and control the light source to send a corresponding second optical signal to the optical information receiver of the participants in each area.

[0104] In this step, the indoor conference venue is divided into several areas based on the location information and language requirements of the participants collected. For example, if most of the participants in an area have chosen the same language, then this area can be divided into an area specifically for receiving that specific language. By dividing the area, the number of different types of language requirements in each area can be reduced to a certain extent, thereby reducing the number of optical signals of different frequencies in each area, avoiding mutual interference between optical signals of different frequencies, thereby improving the signal transmission quality, and thus improving the experience of the participants; once the area division is completed, the system then controls the light source in each area to emit a second light signal corresponding to the language requirement of the area, which may involve adjusting the intensity and direction of the light source or using a specific modulation frequency.

[0105] As an optional embodiment of the present invention, the step of dividing the indoor conference place into a plurality of areas according to the location information and the language requirement, and controlling the light source to send a corresponding second optical signal to an optical information receiver of a participant in each area includes:

[0106] S41, dividing the indoor conference place into several areas according to the location information and language requirement information of each participant, and obtaining an initial division plan;

[0107] According to the location information and language demand information of the participants, the system divides the indoor conference venue into several areas to form an initial area division plan. The number of people in each area is greater than or equal to the preset number of people. The preset number of people is determined based on the size of the conference venue, the expected total number of participants and the demand ratio of each language. No specific restrictions are made here.

[0108] By setting a minimum number of participants, it can be ensured that there are enough participants in each area, so that resources (such as optical signals for specific languages) can be used effectively, avoiding the allocation of large resources to languages ​​that only a few people need, which helps to improve the overall efficiency and performance of the system.

[0109] As an optional embodiment of the present invention, the step of dividing the indoor conference place into a plurality of areas according to the location information and language requirements of each participant to obtain an initial division scheme includes:

[0110] S411, establishing a data set according to the location information and the language requirement information, wherein the data set includes data points corresponding to each of the conference participants, and the data points include the location information and the language requirement information of the corresponding conference participant;

[0111] Collect the location information and language requirements of the participants and establish a data set containing this information. Each participant is regarded as a data point, whose attributes include location coordinates and selected language. By integrating location and language information, the distribution and needs of participants can be analyzed more accurately, providing the necessary data foundation for subsequent clustering processing. The established data set can support data-driven decision-making processes, such as regional division and resource allocation.

[0112] S412, clustering the data set according to a preset clustering rule to obtain a clustering result, wherein the preset clustering rule includes K-mode clustering and spectral clustering;

[0113] The data set is processed using preset clustering methods, which can group participants into different clusters according to their location and language requirements. The preset clustering rules include K-mode clustering and spectral clustering. K-mode clustering is a clustering algorithm specifically used to process categorical data (non-numerical data). It is a variant of the K-means clustering algorithm and is used to process data sets with discrete attributes. Spectral clustering is a clustering method based on graph theory, which is very effective when processing data sets with complex shapes or high dimensions, such as image segmentation, social network analysis, or any complex structured data sets. These clustering methods can effectively group participants according to their needs, so that people with similar needs are classified into the same category, which helps to determine which regions have participants with high consistency in language requirements, thereby providing a basis for dividing meeting venues.

[0114] S413: Determine an initial division plan for indoor meeting places according to the clustering result.

[0115] Based on the results of clustering processing, the conference venue is divided into several areas, each of which corresponds to one or several language needs. This step provides an initial area division plan based on actual needs and the distribution of participants. As a basis for optimization and adjustment, it helps to rationalize the resource allocation of simultaneous interpretation services and ensure that each area can receive the language that suits its needs.

[0116] S42, optimizing the initial division scheme according to a greedy algorithm to obtain several intermediate division schemes, wherein the optimization goal of the greedy algorithm is to minimize the number of different language requirements in each of the regions;

[0117] In this step, the greedy algorithm is used to optimize the initial partitioning scheme, with the goal of minimizing the number of different language requirements in each region. The greedy algorithm is an algorithm that seeks local optimal solutions. At each step, the option that currently appears to be the best is selected. By reducing the language diversity in each region, the complexity of the system and potential interference are reduced, and the transmission efficiency is improved.

[0118] Specifically, during the optimization iteration process of the greedy algorithm, an attempt is made to divide a participant from one area to another, and the impact of this movement on the optimization goal is calculated. When redividing the area, the illumination range and intensity of the light source need to be considered to ensure that each area is covered by sufficient light.

[0119] As an optional embodiment of the present invention, the steps of optimizing the initial partitioning scheme according to a greedy algorithm to obtain several intermediate partitioning schemes include:

[0120] S421. Analyze the current division scheme to obtain the concentration of language demand in each region, wherein the concentration of language demand is calculated by the following formula:

[0121]

[0122] Where HHI is the concentration of the language demand, Si is the proportion of people who demand the i-th language in the current region, n is the total number of language demands in the current region, n and i are both positive integers and 1≤i≤n;

[0123] Specifically, we analyze the current regional division scheme and calculate the concentration of language demand in each region. This is an indicator that measures the concentration of a specific language in a region, similar to the Herfindahl-Hirschman Index in economics. By calculating the HHI, we can identify which regions have a more concentrated language demand and which have a more dispersed demand.

[0124] For example, suppose that in region A, 40 people need English translation, 30 people need French translation, and 20 people need German translation. The total number of people is 40+30+20=90. The proportion of English is 40 / 90≈44.4%, French is 30 / 90≈33.3%, and German is 20 / 90≈22.2%. Using the above formula, the HHI of region A can be calculated as (0.444). 2 +(0.333) 2 +(0.222) 2 ;

[0125] The higher the HHI value, the more concentrated the language demand in the region. If the HHI value is close to 1, it means that there is almost only one language demand in the region; if the HHI value is low, it means that the language distribution is relatively even; this method can quantitatively evaluate the concentration of language demand in each region, providing strong data support for subsequent regional optimization.

[0126] S422, taking the region with the lowest language demand as the first target optimization region;

[0127] Specifically, the area with the lowest concentration of language demand is selected as the first target area for optimization, and the focus is on the areas that need optimization the most, that is, those areas where language demand is most dispersed.

[0128] S423: According to the location information of the conference participants, any conference participant located at the boundary of the first target optimization area is divided into an area adjacent to the first target optimization area, which is recorded as a second target optimization area;

[0129] In this step, the participants at the border of the first target area are divided into adjacent areas. By adjusting the distribution of participants on the border, an attempt is made to increase the concentration of language requirements and make the area division more reasonable.

[0130] S424, calculating the concentration of language requirements of the first target optimization area and the second target optimization area after re-division;

[0131] Recalculate the concentration of language demand in the adjusted first and second target areas to ensure that the adjustment is positive for the overall regional division plan and does not reduce the efficiency of other areas.

[0132] S425. If the concentration of language requirements after the first target optimization area is re-divided is greater than the concentration of language requirements before the re-division, and the concentration of language requirements after the second target optimization area is re-divided is greater than or equal to the concentration of language requirements before the re-division, the current division scheme is used as the intermediate division scheme, and the process returns to the step of analyzing the current division scheme to obtain the concentration of language requirements of each area until the preset end condition is met;

[0133] Specifically, if the concentration of language requirements after the first target optimization area is re-divided is greater than the concentration of language requirements before re-dividing, and the concentration of language requirements after the second target optimization area is re-divided is greater than or equal to the concentration of language requirements before re-dividing, that is, the required concentration of the first target optimization area is increased and the concentration of the second target optimization area is not reduced, then this adjustment is adopted, this scheme is recorded as the intermediate division scheme, and the process returns to step S421 to continue optimizing the scheme until the preset end condition is met;

[0134] S426. If the concentration of language requirements after the first target optimization area is re-divided is less than or equal to the concentration of language requirements before re-dividing, or if the concentration of language requirements after the second target optimization area is re-divided is less than the concentration of language requirements before re-dividing, cancel the adjustment and return to the step of dividing any participant located at the boundary of the first target optimization area into an area adjacent to the first target optimization area according to the location information of the participant, and record it as the second target optimization area, until the preset end condition is met;

[0135] The preset end condition includes that the number of iterations is greater than or equal to the preset number of iterations, or the number of consecutive undo adjustments is greater than or equal to the preset number of undo adjustments.

[0136] If the concentration of language requirements after the first target optimization area is re-divided is less than or equal to the concentration of language requirements before re-dividing, or the concentration of language requirements after the second target optimization area is re-divided is less than the concentration of language requirements before re-dividing, that is, the adjustment fails to improve the concentration or causes the concentration of other areas to decrease, then the adjustment is canceled, and other adjustments are tried before the end condition is met, that is, return to step S423, reselect another participant at the boundary for re-division or divide the previous participant into another adjacent area;

[0137] In this embodiment, the preset end condition includes that the number of iterations is greater than or equal to the preset number of iterations, or the number of consecutive undo adjustments is greater than or equal to the preset number of undo adjustments. In some cases, the algorithm may fall into a state where it cannot be improved, or continue to make small adjustments without achieving significant improvement. Setting the preset number of iterations and the preset number of undo adjustments can prevent the algorithm from looping infinitely.

[0138] In real applications, reaching a "good enough" solution is often more important than finding the absolute optimal solution. Setting a maximum number of iterations can help find a solution that is acceptable in real applications.

[0139] S43, evaluating each of the intermediate division schemes according to a preset evaluation rule to obtain an evaluation result;

[0140] The intermediate division scheme obtained by the greedy algorithm is evaluated, and the efficiency and effectiveness of each scheme are determined using preset evaluation rules. The preset evaluation rules may include coverage evaluation, which measures the proportion of participants covered by language requirements in each area. If most participants in an area choose English, then the coverage of the area is high; conversely, if the language requirements of participants in an area are dispersed, then the coverage is low; or, uniformity evaluation, which evaluates the uniformity of regional division, that is, whether the number of participants and language requirements in each area are evenly distributed. If the number of participants in each area is similar and the language distribution is uniform, then the uniformity is high; if there are too many or too few people in a certain area, the uniformity is low; resource utilization evaluation, which evaluates the utilization efficiency of simultaneous interpretation resources (such as light sources, transmission bandwidth). If the light source in an area can effectively serve all the requirements of the area without waste, then the resource utilization is high;

[0141] As an optional embodiment of the present invention, the step of evaluating each of the intermediate division schemes according to a preset evaluation rule to obtain an evaluation result includes:

[0142] S431, evaluating the intermediate division scheme according to the preset number of ideal regions to obtain a first score;

[0143] Each intermediate division scheme is evaluated according to a preset number of ideal areas, wherein the number of ideal areas is set based on the size of the conference room or the number of participants, and this step evaluates the degree of closeness to the preset number of ideal areas; the first score can be based on the degree of closeness to the ideal number, for example, calculated using an absolute difference or a percentage difference;

[0144] S432, evaluating the intermediate division scheme based on the concentration of language demand in each region in the intermediate division scheme to obtain a second score;

[0145] The calculation method of the second scoring concentration is the same as above and will not be repeated here. By increasing the concentration of language demand, the overlap and interference of multiple languages ​​in the same area can be reduced, thereby improving the efficiency and quality of interpretation. If most of the participants in a region need simultaneous interpretation of the same language, then the simultaneous interpretation service in this region will be more focused and efficient. The second scoring can be calculated based on the average value of the concentration.

[0146] S433, evaluating the intermediate division scheme according to the light source parameters of the light source and the position information and shape information of each area in the intermediate division scheme to obtain a third score, wherein the light source parameters include emission power, illumination angle, and illumination intensity;

[0147] Consider the parameters of the light source, such as emission power, illumination angle, and light intensity, as well as the location and shape information of the area to evaluate the division scheme, such as uniformity and coverage. If the shape and location of an area make the light source coverage more uniform, the area may get a higher score;

[0148] Each area is given a score based on the uniformity and efficiency of the light source coverage, and the third score can be the average or weighted average of these scores.

[0149] In one embodiment, the step S433 specifically includes:

[0150] S4311. Acquire light source parameters, wherein the light source parameters include emission power, irradiation angle, and light intensity;

[0151] Specifically, in the present embodiment, the light source is a directional light source. Unlike ordinary scattered light sources, the light emitted by the directional light source presents a smaller divergence angle and is concentrated in a specific direction. Since the light propagates within a narrow angle range, this light source can provide a higher light intensity in a specific area. In visible light communication, the directional light source can provide high-quality communication signals by concentrating the light. Transmitted power is the intensity of the light emitted by the light source, usually expressed in watts (W) or lumens (lm). Higher transmitted power can enhance the strength and coverage of the signal, but may result in higher power consumption. The irradiation angle determines the degree of diffusion and coverage of the light. A narrower irradiation angle can concentrate the light in a specific area, while a wider angle can expand the coverage. Light intensity refers to the luminous flux of the light source per unit area, and the light intensity affects the quality and visibility of the signal. Higher light intensity helps improve communication quality.

[0152] S4312, calculating the light source coverage effect of each area according to the light source parameters and the area position information and shape information, wherein the light source coverage effect includes uniformity and coverage;

[0153] Specifically, first, the coverage of each light source is calculated based on the emission power, irradiation angle and illumination intensity of the light source, combined with the position and direction of the light source, and the irradiation effect of the light source can be simulated by ray tracing, ray projection or geometric calculation;

[0154] Determine the intensity and range of light in each area. Calculate the light intensity distribution in each area based on the light source's coverage in each area. Use statistical methods such as standard deviation or coefficient of variation to assess the uniformity of light in the area. Light uniformity can be measured by the smoothness of the light intensity distribution in the area.

[0155] S4313, obtaining a score for each area in the intermediate division scheme according to the uniformity and coverage;

[0156] Specifically, the score of each area is calculated based on the uniformity and coverage of each area, and a weighted score is required based on the relative importance of these two parameters. By adjusting the weights, it can be ensured that the evaluation results meet the goals and actual needs of the system. Among them, the weight of uniformity is less than the weight of coverage;

[0157] S4314. Obtain a third score of the intermediate evaluation scheme according to the score of each region and the area of ​​each region.

[0158] Get the score of each region from the previous step, which is a combination of uniformity and coverage. Get the area of ​​each region, which is usually calculated based on the shape and boundary information of the region. Calculate the weighted score based on the score and area of ​​each region, and add up the weighted scores of all regions to get the third score of the intermediate division scheme. In this way, the score and area of ​​each region can be comprehensively considered to get the overall third score of the intermediate division scheme. It helps to evaluate and optimize the overall performance of the simultaneous interpretation system.

[0159] S434: Perform a weighted operation on the first score, the second score, and the third score to obtain an evaluation result of the intermediate division scheme.

[0160] Finally, the three scores are weighted to obtain a comprehensive evaluation result. The weight distribution should be based on the importance of each evaluation aspect to the entire simultaneous interpretation system. This distribution usually depends on the specific scene needs and priorities. For example, if the meeting involves multiple languages, the concentration of language needs may be a key factor, so the weight of the second score can be relatively high; for meetings that require precise technical interpretation, light source parameters and regional characteristics, the third score may be more important to ensure the quality of interpretation. In large spaces, the ideal number of areas (first score) may be more important because the distribution of a large number of participants needs to be effectively managed.

[0161] S44, obtaining a target division scheme according to the evaluation result, the target division scheme;

[0162] Based on the evaluation results, the optimal area division scheme was selected as the target scheme, ensuring that the final division scheme adopted could provide the most efficient simultaneous interpretation service while taking into account the needs and location layout of the participants.

[0163] S45. According to the language requirement of each area in the target division scheme, control the light source to emit a second optical signal to the optical information receiver of the conference participants in each area at a communication carrier frequency corresponding to the language requirement.

[0164] According to the final area division plan, the light source is controlled to send a second optical signal to the participants in each area according to the corresponding communication carrier frequency required by the language. This step ensures that the participants in each area can receive the signal in the language they need, improving the user experience and the overall efficiency of the system.
