Description

[0001] This application is a divisional application of the invention patent application with the application number 202410541984.8, the title of which is "Simultaneous Interpretation Method, Device and Equipment and Medium Based on Indoor Visible Light Communication", and which was filed on April 30, 2024. TECHNICAL FIELD

[0002] The present application relates to the technical field of optical carrier information communication, and in particular to a regional shunt method, device, equipment and medium for LED optical carrier information transmission. BACKGROUND

[0003] Indoor visible light communication (VLC) is a communication technology that uses the visible light band for data transmission. VLC uses light sources (such as LED lamps) to emit modulated light signals, which are received and demodulated by light detectors (such as photodiodes), thereby achieving 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] Simultaneous interpretation, as a real-time language translation service, plays an important role in international conferences, multilingual events and other occasions. With the increasing frequency of international exchanges, the demand for simultaneous interpretation systems has also grown. Traditional simultaneous interpretation systems usually rely on radio frequency or infrared transmission technology, but these technologies are susceptible to interference and have the problem of frequency congestion in high-density usage scenarios. Simultaneous interpretation systems based on VLC use spectral resources and can provide more stable, efficient and secure services, especially in indoor environments where information security and electromagnetic interference reduction are required.

[0005] Currently, a patent with the authorization announcement number CN108599844B discloses a simultaneous interpretation device based on visible light communication technology and its working method, which uses LDPC encoding and PPM modulation method. PPM relies on the time position of pulses to encode information, which requires very precise time synchronization between the receiver and the transmitter. Inaccurate time synchronization can cause data decoding errors, and with each additional language, a unique time encoding pattern needs to be added in PPM modulation. As the number of languages increases, maintaining the uniqueness and distinguishability of each pulse becomes more complex.

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

[0064] Embodiment 1

[0065] Please refer to Figure 1 In a first aspect, the embodiment of the present application provides a simultaneous interpretation method based on indoor visible light communication, the method comprising:

[0066] For at least one of the participants wearing an optical carrier information receiver:

[0067] S1, according to the first light signal received by the optical carrier information receiver of each participant, obtaining the position information of each participant in the indoor conference place;

[0068] Specifically, first, the light source in the system emits a first light signal containing specific coded information for subsequent positioning process, the participants in the conference venue are equipped with light-borne information receivers, which include photosensitive diodes or light sensors, etc., the light-borne information receivers can detect and receive the first light signal emitted from the light source, and measure and analyze various parameters of the signal, such as signal strength, angle of arrival and time of arrival, etc., based on the parameters of the received first light signal, the specific position of each receiver, i.e. the position of each participant, is calculated through a positioning algorithm, which includes but is not limited to time difference positioning algorithm and triangular positioning algorithm, etc., the above positioning algorithms are prior art and will not be described here.

[0069] Through this step, the system can obtain the accurate position information of each participant, which is crucial for efficient simultaneous interpretation, accurate position information can provide personalized services for each participant, such as sending translation in a specific language to their position, accurate positioning information also helps the system to manage resources more effectively, such as accurately controlling the irradiation direction and intensity of the light source, reducing energy waste.

[0070] As an optional embodiment of the present application, the step of obtaining the position information of each participant in the indoor conference venue according to the first light signal received by the light-borne information receiver of each participant includes:

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

[0072] In this step, the light source is controlled to send a specific first light signal, the first light signal 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, using a specific carrier frequency ensures that the receiver can accurately identify the signal for positioning, reducing the interference of ambient light.

[0073] S12, obtaining the actual signal parameters of the first light signal received by each light-borne information receiver, wherein the actual signal parameters include signal strength, angle of arrival and time difference of arrival;

[0074] Specifically, after the receiver receives the first light signal, the actual signal parameters of the first light signal are measured, including signal strength, angle of arrival and time difference of arrival, signal strength represents the intensity or intensity level of the received light signal, angle of arrival represents the angle of the light signal when it arrives at the receiver, and time difference of arrival is the time difference of the same signal received by different light sensor units of the receiver; these parameters provide key data for calculating the accurate position of each participant, by comprehensively analyzing these parameters, the positioning sensitivity and accuracy of the system can be greatly improved.

[0075] S13、According to the actual signal parameters, the position information of each participant is obtained.

[0076] According to the signal parameters collected in S12, the specific position of each participant is calculated using a specific algorithm, including triangulation, signal strength-based positioning, or time difference of arrival-based positioning, etc., to accurately determine the position of each participant in the conference venue, laying the foundation for providing customized simultaneous interpretation services;

[0077] S2, Obtain the language needs of each participant, and bind the position information of each participant and the language needs;

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

[0079] Specifically, the language needs of each participant can be selected on the display interface of the receiver, which displays multiple language options. In a specific embodiment, before selecting the language 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 displaying the corresponding language options on the display interface according to the system default language; Users can choose the language they need to ensure that each participant can receive the translation content they need. By obtaining the default language of the device, the system can pre-identify and recommend the possible language needs of the user, thereby simplifying the selection process and improving user experience.

[0080] S3, The audio data corresponding to each language requirement is encoded and modulated to obtain a plurality of second optical signals, wherein the communication carrier frequencies of each second optical signal are different;

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

[0082] As an optional embodiment of the present application, the step of encoding and modulating the audio data corresponding to each language requirement to obtain a plurality of second optical signals comprises:

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

[0084] The real-time ambient light data of the current environment is collected using a light sensor, and the real-time ambient light data includes ambient light intensity and spectral distribution. These data provide important information about the current ambient light conditions, which helps to optimize the subsequent frequency allocation and modulation process.

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

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

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

[0088] S33, allocating a plurality of candidate communication frequencies to the target translation audio data corresponding to each language requirement in the communication light frequency interval;

[0089] This step allocates a plurality of candidate communication frequencies to different languages within the determined communication light frequency interval, ensuring that each language has an appropriate frequency available while reducing interference between different frequencies.

[0090] Specifically, a plurality of candidate communication frequencies are allocated to each language requirement within the determined communication light frequency interval, which may be based on various factors such as the number of languages, the priority of each language, etc. When allocating, avoid excessive proximity between frequency points to reduce mutual interference. For example, avoid setting candidate frequencies too close to prevent confusion between signals of two languages.

[0091] For example, but not limited to, a VLC system of an indoor conference site needs to support simultaneous interpretation of English, French, Spanish and German. After spectrum sensing algorithm analysis, the system determines that the frequency interval of 650nm to 750nm is most suitable for communication, and the system can set one 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, which is determined according to the communication light frequency interval and the number of language requirements, which is not limited here.

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

[0093] The signal-to-noise ratio (SNR) of each alternative frequency is calculated to evaluate its communication quality. The signal-to-noise ratio (SNR) is an indicator of signal quality, which is the ratio of signal strength to background noise. A high signal-to-noise ratio frequency will provide clearer and more stable communication.

[0094] S35, in the several alternative communication frequencies corresponding to each target translation audio data, selecting the alternative communication frequency with the highest signal-to-noise ratio as the target communication frequency;

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

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

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

[0098] If the spectrum type of the target communication frequency is green light, differential Manchester encoding is selected as the encoding strategy, and PAM modulation strategy is helpful to realize high-quality transmission of data in green light communication, differential Manchester encoding is used to provide clock synchronization of data, and PAM modulation mode uses different light intensity levels to represent data, thereby improving the reliability of data transmission, and this combination helps to realize higher transmission stability in green light communication, reduce data transmission error rate;

[0099] If the spectrum type of the target communication frequency is blue light, 8B / 10B line encoding is selected as the encoding strategy, and QAM modulation strategy is very effective for blue light communication, 8B / 10B encoding is a data encoding method for providing data reliability and synchronization, while QAM modulation mode combines amplitude and phase modulation, allowing more data to be transmitted within limited bandwidth. This strategy combination helps to realize high-speed data transmission in blue light communication and reduces the risk of signal distortion;

[0100] If the spectrum type of the target communication frequency is white light, Turbo encoding is selected as the encoding strategy, and CAP modulation strategy is helpful to realize high fault tolerance and high-speed transmission in white light communication. Turbo encoding is a powerful error correction encoding method that can reduce the error rate in data transmission, and CAP modulation mode combines amplitude and phase modulation, suitable for high-speed visible light communication. This strategy combination helps to realize 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 encoding rule, the target translation 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 the selected modulation and encoding method to obtain the second optical signal for transmission, ensuring efficient and accurate data transmission. Each language signal is optimized to adapt to specific communication frequencies and environmental conditions. Through these steps, the embodiment of the present application can provide the most optimized communication frequency selection and signal processing scheme for different languages under different environmental conditions, thereby improving the overall performance and user experience of the simultaneous interpretation system.

[0103] S4, according to the position information and the language demand, the indoor conference place is divided into several areas, and the light source emits the corresponding second optical signal to the light carrier information receiver of the participants in each area.

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

[0105] As an optional embodiment of the present application, the step of dividing the indoor conference venue into several areas according to the location information and language needs of the participants, and controlling the light source to emit a corresponding second light signal to the light-carried information receiver of the participants in each area, comprises:

[0106] S41, according to the location information and language needs information of each participant, the indoor conference venue is divided into several areas, and an initial division scheme is obtained;

[0107] According to the location information and language needs information of the participants, the system divides the indoor conference venue into several areas to form an initial area division scheme, and the number of people in each area is greater than or equal to a preset number, which is determined based on the size of the conference venue, the total number of expected participants, and the demand proportion of each language, and is not limited here.

[0108] By setting a minimum number limit, it can be ensured that there are enough participants in each area, so that resources (such as light signals of a specific language) can be effectively utilized, and a large amount of resources can be allocated for a language 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 application, the step of dividing the indoor conference venue into several areas according to the location information and language needs of the participants, and obtaining an initial division scheme, comprises:

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

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

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

[0113] The data set is processed using the preset clustering method, which can group participants into different clusters according to their location and language needs. The preset clustering rule includes K-mode clustering and spectral clustering. K-mode clustering is a clustering algorithm specifically designed for categorical data (non-numeric data) and is a variant of the K-means clustering algorithm for processing data sets with discrete attributes. Spectral clustering is a graph theory-based clustering method that is very effective in processing complex-shaped or high-dimensional data sets, such as image segmentation, social network analysis, or any complex-structured data set. These clustering methods can effectively group participants according to their needs, so that people with similar needs are classified into the same category, helping to determine which areas of the conference have a high degree of consistency in language needs, thereby providing a basis for dividing the conference venue.

[0114] S413, according to the clustering result, an initial division scheme of the indoor conference venue is determined.

[0115] According to the results of the clustering process, the conference venue is divided into several regions, each corresponding to one or several language needs. This step provides an initial regional division scheme based on actual needs and participant distribution, serving as a basis for optimization and adjustment, and helps to rationalize the allocation of simultaneous interpretation services resources, ensuring that each region receives the appropriate language for its needs.

[0116] S42, according to the greedy algorithm, the initial division scheme is optimized to obtain several intermediate division schemes, wherein the optimization target of the greedy algorithm is to minimize the number of different language needs in each region;

[0117] In this step, the greedy algorithm is used to optimize the initial division scheme, with the goal of minimizing the number of different language needs in each region. The greedy algorithm is an algorithm that seeks local optimal solutions, choosing the best option at each step. By reducing the language diversity within each region, the complexity and potential interference of the system are reduced, improving transmission efficiency.

[0118] Specifically, in the optimization iteration process of the greedy algorithm, an attempt is made to move a participant from one region to another, and the impact of this movement on the optimization target is calculated. When re-dividing the regions, the illumination range and intensity of the light source need to be considered to ensure that each region is covered by sufficient light.

[0119] As an optional embodiment of the present application, the step of optimizing the initial division scheme according to the greedy algorithm to obtain a plurality of intermediate division schemes comprises:

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

[0121]

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

[0123] Specifically, the current region division scheme is analyzed to calculate the concentration of language demand of each region, which is an index to measure the concentration of a specific language in a region, similar to the Herfindahl-Hirschman Index in economics. By calculating HHI, it can be identified which regions have more concentrated language demand and which have more dispersed language demand.

[0124] For example, assume that region A has 40 people who need English translation, 30 people who need French translation, and 20 people who need German translation, for a total of 40+30+20=90 people. The proportion of English is 40 / 90≈44.4%, the proportion of French is 30 / 90≈33.3%, and the proportion of German is 20 / 90≈22.2%. According to the above formula, the HHI of region A is (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 the region almost only has one language demand. If the HHI value is low, it means that the language distribution is relatively uniform. Through this method, the concentration of language demand in each region can be quantitatively evaluated, providing strong data support for subsequent region optimization.

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

[0127] Specifically, the region with the lowest concentration of language needs is selected as the first target region for optimization, focusing on the region that most needs optimization, i.e., the region with the most dispersed language needs.

[0128] S423, according to the location information of the participants, any participant located at the boundary of the first target optimization region is divided into a region adjacent to the first target optimization region, denoted as the second target optimization region;

[0129] In this step, the participants located at the boundary of the first target region are divided into adjacent regions, and the distribution of participants at the boundary is adjusted to try to improve the concentration of language needs and make the regional division more reasonable;

[0130] S424, the concentration of language needs of the first target optimization region and the second target optimization region after redivision is calculated;

[0131] The concentration of language needs of the first and second target regions after adjustment is recalculated to ensure that the adjustment is positive to the overall regional division scheme and does not reduce the efficiency of other regions.

[0132] S425, if the concentration of language needs of the first target optimization region after redivision is greater than the concentration of language needs before redivision, and the concentration of language needs of the second target optimization region after redivision is greater than or equal to the concentration of language needs before redivision, the current division scheme is taken as an intermediate division scheme, and the step of analyzing the current division scheme to obtain the concentration of language needs of each region is returned until the preset ending condition is met;

[0133] Specifically, if the concentration of language needs of the first target optimization region after redivision is greater than the concentration of language needs before redivision, and the concentration of language needs of the second target optimization region after redivision is greater than or equal to the concentration of language needs before redivision, i.e., the concentration of the first target optimization region is improved and the concentration of the second target optimization region is not reduced, this adjustment is adopted, and this scheme is recorded as an intermediate division scheme, and the optimization of the scheme is continued in step S421 until the preset ending condition is met.

[0134] S426, if the concentration of language needs of the first target optimization region after redivision is less than or equal to the concentration of language needs before redivision, or the concentration of language needs of the second target optimization region after redivision is less than the concentration of language needs before redivision, the adjustment is cancelled and the step of dividing any participant located at the boundary of the first target optimization region into a region adjacent to the first target optimization region, denoted as the second target optimization region, according to the location information of the participants is returned until the preset ending condition is met.

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

[0136] If the concentration of the language demand of the first target optimization region after the redivision is less than or equal to the concentration of the language demand before the redivision, or the concentration of the language demand of the second target optimization region after the redivision is less than the concentration of the language demand before the redivision, that is, the adjustment fails to improve the concentration or leads to a decrease in the concentration of other regions, the adjustment is reversed, and other adjustments are continuously attempted before the ending condition is met, that is, returning to step S423 to reselect another participant located at the boundary for redivision or divide the previous participant into another adjacent region.

[0137] In this embodiment, the preset ending condition includes that the number of iterations is greater than or equal to a preset number of iterations, or the number of consecutive adjustments is greater than or equal to a preset number of reversals. In some cases, the algorithm may be trapped in a state of being unable to improve, or continuously make small adjustments without achieving significant improvement. Setting the preset number of iterations and the preset number of reversals can prevent the algorithm from being in an infinite loop.

[0138] In actual applications, it is usually more important to find a solution that is “good enough” than to find an absolutely optimal solution. Setting the maximum number of iterations can help find a solution that is acceptable in actual applications.

[0139] S43, evaluating each intermediate division scheme according to a preset evaluation rule to obtain an evaluation result.

[0140] The intermediate division schemes obtained by the greedy algorithm are evaluated, and a preset evaluation rule is used to determine the efficiency and effectiveness of each scheme. The preset evaluation rule can include coverage evaluation, which measures the proportion of participants in each region who choose a language. If most participants in a region choose English, the coverage of the region is high. Conversely, if the language demand of participants in a region is scattered, the coverage is low. Alternatively, uniformity evaluation can be used to evaluate the uniformity of the region division, that is, whether the number of participants and the distribution of language demand in each region are balanced. If the number of participants in each region is similar and the language distribution is uniform, the uniformity is high. If the number of participants in a region is too high or too low, the uniformity is low. Resource utilization rate evaluation can be used to evaluate the utilization efficiency of simultaneous interpretation resources (such as light sources and transmission bandwidth). If the light source of a region can effectively serve all the demands of the region without waste, the resource utilization rate is high.

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

[0142] S431、According to the preset ideal region quantity, the intermediate division scheme is evaluated to obtain a first score;

[0143] According to the preset ideal region quantity, each intermediate division scheme is evaluated, and the preset ideal region quantity is set based on the size of the conference room or the number of participants. This step evaluates the proximity to the preset ideal region quantity. The first score can be calculated based on the degree of proximity to the ideal quantity, for example, using an absolute difference or a percentage difference;

[0144] S432、According to the concentration of language demand of each region in the intermediate division scheme, the intermediate division scheme is evaluated to obtain a second score;

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

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

[0147] The parameters of the light source, such as emission power, illumination angle, illumination intensity, and the position and shape information of the region, are considered to evaluate the division scheme, such as uniformity, coverage range, etc. If the shape and position of a region make the light source coverage more uniform, the region may get a higher score;

[0148] For each region, a score is given according to the uniformity and efficiency of light source coverage. The third score can be the average or weighted average of these scores.

[0149] In an embodiment, the step S433 specifically comprises:

[0150] S4311、Obtain light source parameters, wherein the light source parameters include emission power, illumination angle and illumination intensity;

[0151] Specifically, in this embodiment, the light source is a directional light source, unlike ordinary diffuse light sources, the directional light source emits light with a small divergence angle, concentrated in a specific direction. Because the light propagates in a narrow angle range, such a light source can provide higher light intensity in a certain area. In visible light communication, a directional light source can provide high-quality communication signals by concentrating light. The emission power is the intensity of the light emitted by the light source, usually expressed in watts (W) or lumens (lm). Higher emission power can enhance the intensity and coverage of the signal, but may result in higher power consumption. The illumination angle determines the degree of light diffusion and coverage. A narrower illumination angle can concentrate light in a specific area, while a wider angle can expand the coverage. The illumination intensity refers to the luminous flux per unit area of the light source, and the illumination intensity affects the quality and visibility of the signal. Higher illumination intensity helps improve communication quality.

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

[0153] Specifically, first, according to the emission power, illumination angle and illumination intensity of the light source, combined with the position and direction of the light source, the coverage range of each light source is calculated. The illumination effect of the light source can be simulated by ray tracing, ray projection or geometric calculation, etc.

[0154] Determine the illumination intensity and range of the light in each area. According to the coverage effect of the light source in each area, calculate the light intensity distribution in each area. Use statistical methods such as standard deviation or coefficient of variation to evaluate the uniformity of the light in the area. The uniformity of the light can be measured by the smoothness of the light intensity distribution in the area.

[0155] S4313, according to the uniformity and coverage, obtain the score of each area in the intermediate division scheme;

[0156] Specifically, the score of each area is calculated according to the uniformity and coverage of each area. The relative importance of the two parameters needs to be weighted to score. By adjusting the weight, it can be ensured that the evaluation result meets the system's goals and actual needs. Among them, the weight of the uniformity is less than the weight of the coverage;

[0157] S4314, according to the score of each area and the area of each area, obtain the third score of the intermediate evaluation scheme.

[0158] The score of each region is obtained from the previous step, which integrates uniformity and coverage. The area of each region is obtained, which is usually calculated according to the shape and boundary information of the region. The weight score is calculated according to the score and area of each region, and the weight scores of all regions are accumulated to obtain the third score of the intermediate division scheme. In this way, the score and area of each region can be considered comprehensively to obtain the overall third score of the intermediate division scheme. It is helpful to evaluate and optimize the overall performance of the simultaneous interpretation system.

[0159] S434, the first score, the second score and the third score are weighted to obtain the evaluation result of the intermediate division scheme.

[0160] Finally, the three scores are weighted to obtain a comprehensive evaluation result. The distribution of weights should be based on the importance of each evaluation aspect to the entire simultaneous interpretation system. This distribution usually depends on the specific scene requirements and priorities. For example, if the conference involves multiple languages, the concentration of language requirements may be a key factor, so the weight of the second score can be relatively high. For conferences that require accurate technical interpretation, the third score may be more important to ensure the quality of interpretation. In large spaces, the number of ideal regions (first score) may be more important because it is necessary to effectively manage the distribution of a large number of participants.

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

[0162] Based on the evaluation result, the optimal region division scheme is selected as the target scheme, ensuring that the final adopted division scheme can provide the most efficient simultaneous interpretation service, while considering the needs and location layout of the participants.

[0163] S45, according to the language requirement of each region in the target division scheme, controlling the light source to emit a second optical signal to the optical carrier information receiver of the participants in each region with a corresponding communication carrier frequency of the language requirement.

[0164] According to the final region division scheme, the light source is controlled to emit a second optical signal to the participants in each region with a corresponding communication carrier frequency of the language requirement, which ensures that the participants in each region can receive the signal of their required language, improving user experience and overall efficiency of the system.
