Description

Technical Field

[0001] The present invention relates to the technical field of digital radio broadcasting, and in particular to a DRM broadcasting service modeling method based on simulation deduction. Background Art

[0002] Digital Radio Mondiale (DRM) is a digital broadcasting technology system that supports both digital voice broadcasting and the delivery of digital services such as news, weather and ocean forecasts, and the Automatic Identification System (AIS).

[0003] It should be noted that DRM shortwave broadcasting, unlike digital communications, requires reporting to the International Telecommunication Union (ITU) information such as broadcast coverage (or ITU region), longitude and latitude, and broadcast time. Once DRM shortwave broadcasting is officially launched, the broadcasting operation diagram cannot be changed at will unless there are special circumstances. Therefore, the DRM broadcasting operation diagram is often optimized through simulation and deduction. That is, under the premise of certain broadcast station resources, the operation plan with the best broadcast reception effect is selected (for example, setting each transmitter of each station to broadcast preset content to a specified area within its own designated time range), thereby providing support for the comprehensive implementation of DRM upgrades and renovations. The generation of DRM broadcast simulation services is an essential element for conducting DRM simulation and deduction.

[0004] Currently, research on simulated traffic generation has largely focused on the communications field. Existing methods primarily analyze and sort out the logical relationships between the sending end node (Original) and the receiving end node (Destination) (abbreviated as "OD" pairs), and then model communication traffic generation based on these existing "OD" relationships. However, because DRM broadcasting is a one-way broadcast communication mode, there is no "OD" relationship between the transmitting station and the DRM shortwave receiver. Existing communication traffic simulation generation techniques rely on analyzing the logical relationships between existing "OD" pairs, making them difficult to apply to DRM broadcast simulation generation and unsuitable for optimizing DRM broadcast operation diagrams. Summary of the Invention

[0005] The present invention provides a DRM broadcast service modeling method based on simulation deduction, which is used to solve the defect that the existing communication service simulation generation technology is difficult to apply to the generation of DRM broadcast simulation services. The existing technology is not suitable for the optimization of DRM broadcast operation diagrams. Through the method provided by the present invention, only some simulation parameters need to be set to realize the generation of simulated DRM broadcast services based on the simulation platform.

[0006] The present invention provides a DRM broadcast service modeling method based on simulation deduction, which specifically includes:

[0007] According to the average volume of broadcast services per unit time in a historical broadcast cycle, the average intensity of the broadcast services is obtained, a broadcast service intensity model is established, and the time interval of the broadcast services and the volume of each broadcast service are simulated and set using the broadcast service intensity model;

[0008] Obtaining the broadcast frequency ratios of various types of broadcast services during a historical broadcast cycle, arranging the broadcast frequency ratios of the various types of broadcast services, and defining a numerical range for each type of broadcast service; determining, based on a preset random number input into the broadcast service intensity model, which type of broadcast service the random number falls within, and generating a corresponding type of broadcast service using the broadcast service intensity model;

[0009] Establishing an adjustment coefficient model for broadcast service intensity based on the types and intensities of broadcast services under different environmental conditions during historical broadcast cycles, setting an adjustment coefficient based on the adjustment coefficient model according to current environmental conditions, and adjusting the traffic intensity simulated by the broadcast service intensity model;

[0010] The broadcast operation diagram is simulated based on the established broadcast business intensity model.

[0011] According to a DRM broadcast service modeling method provided by the present invention, if the broadcast service is continuously broadcast within a fixed period of time, the established broadcast service intensity model includes:

[0012] Obtain the time interval Δt of the continuous broadcast service to generate digital voice data packets, and use the inverse of the time interval 1 / Δt as the generation intensity of the digital voice data packets. The broadcast time [t i ,t j The number of digital voice data packets generated in ] is:

[0013]

[0014] The broadcast traffic for continuous broadcast is evenly distributed and includes:

[0015] (t i ≤t≤t j , c is the broadcast rate).

[0016] According to a simulation-based DRM broadcast service modeling method provided by the present invention, if a broadcast service is generated once every certain period of time within a fixed period of time, and different types of broadcast services are independent of each other, then the broadcast service is a Poisson flow model:

[0017]

[0018] Where λ is the average number of data broadcast services generated per unit time, also known as the average intensity of data broadcast services; P k represents the probability of generating k data broadcast services within the time [0, t]; τ represents the broadcast time.

[0019] According to a simulation-based DRM broadcast service modeling method provided by the present invention, an adjustment coefficient is established based on an adjustment coefficient model according to current environmental conditions to adjust the traffic intensity simulated by the broadcast service intensity model, including:

[0020] The ratio of the intensity of data broadcasting services generated under various environmental conditions to the intensity of data broadcasting services generated under adverse environmental conditions is used as the adjustment coefficient for data broadcasting service simulation generation:

[0021]

[0022] The simulated generation intensity λ of broadcast services under different environmental conditions is v for:

[0023] λ v =b v λ;

[0024] Among them, v represents the severity of environmental conditions. The larger v is, the worse the environment is. The corresponding simulation generation intensity λ v The larger it is, the higher the frequency of the simulated data broadcast service will be.

[0025] According to a simulation-based DRM broadcast service modeling method provided by the present invention, shortwave skywave channels are more commonly used to transmit small-capacity information due to their narrow bandwidth. Relatively speaking, they are less likely to transmit large-capacity data broadcast services. Therefore, the data broadcast service volume generated by the simulation should follow an exponential distribution:

[0026]

[0027] Among them, x i (i=1,2,···,n) represents the broadcast traffic of each category generated by simulation, θ i (i=1,2,···,n) represents the degree of deviation of the broadcast traffic of each category generated by simulation, c i (i=1,2,···,n) represents the lower limit of the broadcast traffic volume of each category generated by simulation, d i (i=1,2,···,n) represents the upper limit of the broadcast traffic of each category generated by simulation;

[0028] Optionally, the service types include but are not limited to three types of data broadcast services: news, meteorological and ocean forecasts, and AIS services.

[0029] The present invention also provides a method for generating a DRM broadcast service through simulation deduction, wherein the broadcast service intensity model established by any of the above-mentioned modeling methods is used to generate the broadcast service. If the broadcast service is continuously broadcast within a fixed time period, the DRM broadcast transmitter location, the number of transmitters, and the broadcast coverage area are read according to the broadcast operation diagram generated by the broadcast service intensity model.

[0030] According to the broadcast operation diagram, the broadcast time period of the DRM broadcast transmitter, the time interval of the broadcast service and the size of the broadcast service are set.

[0031] According to a simulation-based DRM broadcast service generation method provided by the present invention, if a broadcast service is generated once every certain period of time within a fixed period, and different types of broadcast services are independent of each other, then the broadcast service intensity model generates the broadcast service including:

[0032] Reading the DRM broadcast transmitter location, number of transmitters, and broadcast coverage area based on the broadcast operation diagram generated by the broadcast service intensity model;

[0033] The intensity λ generated by the broadcast service simulation is set according to the broadcast service intensity model.

[0034] Input synchronously generates a random number μ between [0,1] i , determining which type of broadcast service the random number falls into, and generating a corresponding type of broadcast service by using the broadcast service intensity model;

[0035] Obtain the real-time environmental conditions of the broadcast area and set the broadcast service simulation generation adjustment coefficient b v , and calculate the generation intensity λ of broadcast services under different environmental conditions v ;

[0036] Input the upper and lower limits of various broadcast traffic volumes;

[0037] Broadcast according to the set broadcast operation diagram.

[0038] The present invention also provides an electronic device comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the steps of any of the above-mentioned DRM broadcast service modeling methods are implemented.

[0039] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of any of the above-mentioned DRM broadcast service modeling methods are implemented.

[0040] The present invention provides a DRM broadcast service modeling method based on simulation deduction, which has at least the following technical effects:

By applying stochastic process theory, it constructs a simulation generation model for various broadcast data services from the overall perspective without the need to study specific details.

[0049] like Figure 1 As shown, in one embodiment, the present invention provides a DRM broadcast service modeling method for simulation deduction, specifically including:

[0050] According to the average volume of broadcast services per unit time in a historical broadcast cycle, the average intensity of the broadcast services is obtained, a broadcast service intensity model is established, and the time interval of the broadcast services and the volume of each broadcast service are simulated and set using the broadcast service intensity model;

[0051] Obtaining the broadcast frequency ratios of various types of broadcast services during a historical broadcast cycle, arranging the broadcast frequency ratios of the various types of broadcast services, and defining a numerical range for each type of broadcast service; determining, based on a preset random number input into the broadcast service intensity model, which type of broadcast service the random number falls within, and generating a corresponding type of broadcast service using the broadcast service intensity model;

[0052] Establishing an adjustment coefficient model for broadcast service intensity based on the types and intensities of broadcast services under different environmental conditions during historical broadcast cycles, setting an adjustment coefficient based on the adjustment coefficient model according to current environmental conditions, and adjusting the traffic intensity simulated by the broadcast service intensity model;

[0053] The broadcast operation diagram is simulated based on the established broadcast business intensity model.

[0054] According to a DRM broadcast service modeling method provided by the present invention, if the broadcast service is a continuous broadcast within a fixed period of time, such as a digital voice broadcast service;

[0055] Since digital voice broadcasting services are available at fixed times every day [t i ,t j ] is broadcast continuously, so it can be assumed that digital voice data packets are generated at a fixed time interval Δt. Therefore, the broadcast service intensity model established by using uniform distribution to construct digital voice broadcasting includes:

[0056] Obtain the time interval Δt of the continuous broadcast service to generate digital voice data packets, and use the inverse of the time interval 1 / Δt as the generation intensity of the digital voice data packets. The broadcast time [t i ,t jThe number k of digital voice data packets generated therein is:

[0057]

[0058] The continuously broadcast radio traffic is uniformly distributed and includes:

[0059] (t i ≤ t ≤ t j , where c is the broadcast rate).

[0060] According to a DRM radio service modeling method for simulation and deduction provided by the present invention, for radio services in a discrete generation mode, such as data broadcast services, a service is generated every certain period of time, and the generation of different types of data broadcast services is independent of each other. Therefore, a Poisson flow model can be used for description:

[0061]

[0062] Among them, λ is the average number of data broadcast services generated per unit time, also known as the average intensity of data broadcast services; P k represents the probability that the number of data broadcast services generated within the time period [0, t] is k; τ represents the broadcast time;

[0063] Among them, obtain the broadcast frequency ratios of various radio services within the historical broadcast period, arrange them according to the magnitudes of the broadcast frequency ratios of various radio services, and define the numerical ranges of each type of radio service; according to the preset random number input into the radio service intensity model, determine which numerical range of radio service the random number falls into, and generate a radio service of the corresponding type by the radio service intensity model, where the service types include, but are not limited to, one or more of news, meteorological and ocean forecasts, and AIS broadcasts;

[0064] As an example, according to the data broadcast service schedule, the broadcast frequency ratios of news, meteorological and ocean forecasts, and AIS within a certain period can be counted. Assume that the statistical data broadcast service ratios of news, meteorological and ocean forecasts, and AIS from small to large are p1, p2, p3 (0 < p1 < p2 < p3 < 1, and p1 + p2 + p3 = 1);

[0065] When generating the i-th simulated data broadcast service, a random number μ between [0, 1] can be generated synchronously i . If 〇 < μ i < p1, the simulated news service is generated this time; if p1 < μ i < p1 + p2, the simulated meteorological and ocean service is generated this time; if p1 + p2 < μ i < 1, the simulated AIS service is generated this time.

[0066] According to a simulation-based DRM broadcast service modeling method provided by the present invention, in order to reflect the intensity changes of data broadcast services generated under different environmental conditions, an adjustment coefficient for data broadcast service simulation is introduced. If the meteorological and oceanographic environment in the broadcast area is worse, the intensity of the data broadcast service generated in the short period of time will be greater, and vice versa. The adjustment coefficient model is used to establish an adjustment coefficient according to the current environmental conditions. Adjusting the service intensity simulated by the broadcast service intensity model includes:

[0067] The ratio of the intensity of data broadcasting services generated under various environmental conditions to the intensity of data broadcasting services generated under adverse environmental conditions is used as the adjustment coefficient for data broadcasting service simulation generation:

[0068]

[0069] The simulated generation intensity λ of broadcast services under different environmental conditions is v for:

[0070] λ v =b v λ;

[0071] Among them, v represents the severity of environmental conditions. The larger v is, the worse the environment is. The corresponding simulation generation intensity λ v The larger it is, the higher the frequency of the simulated data broadcast service will be.

[0072] According to a DRM broadcast service modeling method provided by the present invention, the broadcast service intensity model generates a broadcast service volume of:

[0073]

[0074] Among them, x i (i=1,2,···,n) represents the broadcast traffic of each category generated by simulation, θ i (i=1,2,···,n) represents the degree of deviation of the broadcast traffic of each category generated by simulation, c i (i=1,2,···,n) represents the lower limit of the broadcast traffic volume of each category generated by simulation, d i (i=1, 2, ···, n) represents the upper limit of the size of each category of broadcast traffic generated by simulation.

[0075] On the other hand, in one embodiment, the present invention further provides a method for generating a DRM broadcast service through simulation deduction, wherein the broadcast service is generated based on the broadcast service intensity model established by any of the above modeling methods. If the broadcast service is continuously broadcast within a fixed time period, the DRM broadcast transmitter location, the number of transmitters, and the broadcast coverage area are read according to the broadcast operation diagram generated by the broadcast service intensity model.

[0076] According to the broadcast operation diagram, the broadcast time period of the DRM broadcast transmitter, the time interval of the broadcast service and the size of the broadcast service are set.

[0077] In one embodiment, Figure 2 As shown, according to a simulation-based DRM broadcast service generation method provided by the present invention, if the broadcast service is generated once every certain time within a fixed period, and different types of broadcast services are independent of each other, then the broadcast service intensity model generates the broadcast service including:

[0078] Reading the DRM broadcast transmitter location, number of transmitters, and broadcast coverage area based on the broadcast operation diagram generated by the broadcast service intensity model;

[0079] The intensity λ generated by the broadcast service simulation is set according to the broadcast service intensity model.

[0080] Input synchronously generates a random number μ between [0,1] i , determining which type of broadcast service the random number falls into, and generating a corresponding type of broadcast service by using the broadcast service intensity model;

[0081] Obtain the real-time environmental conditions of the broadcast area and set the broadcast service simulation generation adjustment coefficient b v , and calculate the generation intensity λ of broadcast services under different environmental conditions v ;
