[0002] A broadcast transmitter is an electronic device specifically used for transmitting information. It mainly realizes the long-distance transmission of information by utilizing the propagation characteristics of electromagnetic waves. Through specific technical means, it is adjusted and loaded onto a specific carrier frequency. Once the audio information is adjusted to the carrier wave, this carrier wave signal is amplified to a predetermined power level to ensure that the signal has sufficient intensity to cover the predetermined reception area. Finally, the amplified signal is transmitted through the antenna connected to the broadcast transmitter and propagates in the air in the form of electromagnetic waves to ensure the stable and clear propagation of the broadcast signal within a certain range.

[0003] With the continuous progress of wireless communication technology, the transmission power control technology has gradually transitioned from traditional analog control methods to advanced control strategies based on digital signal processing. By introducing transmission power control algorithms, in densely populated urban areas, in order to reduce signal interference, the algorithm needs to be able to quickly reduce the power output, while in remote areas, in order to cover a wider audience, the algorithm should increase the power to ensure communication quality.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0052] Please refer to Figure 1 As shown, the present invention provides a broadcast transmitter transmission power control system based on big data, including a transmitter signal transmission time division module, a transmitter signal data acquisition module, a transmitter signal interference intensity data analysis module, a transmitter signal transmission performance analysis module, a transmitter transmission power stability evaluation module, a transmitter transmission power control module, and a transmitter transmission power control effect evaluation module.

[0054] The transmitter signal transmission time division module: is used to divide the signal transmission time of the target broadcast transmitter into n monitoring sub-periods at equal time intervals; it is beneficial to independently monitor the transmitted signal data in each sub-period, decouple from other modules, and facilitate system integration.

[0055] In a possible design, the transmitter signal transmission time division module is specifically:

[0056] Synchronize with the time reference of the broadcast transmitter using a high-precision clock source. Based on the number of sub-periods set by the user, divide the signal transmission time of the target broadcast transmitter into each monitoring sub-period at equal time intervals, and sequentially number the signal transmission times of each monitoring sub-period of the target broadcast transmitter as 1, 2,... i,... n. At the start moment of each sub-period, generate a trigger signal for the transmitter signal data acquisition module to start collecting data. At the end moment of each sub-period, generate an end signal for the transmitter signal data acquisition module to stop collecting data.

[0057] Please refer to Figure 2 As shown, the transmitter signal data acquisition module: is used to collect the power fluctuation impact data of each monitoring sub-period of the signal transmission time of the target broadcast transmitter. The transmitter signal data acquisition module includes a transmitter interference signal data acquisition unit and a transmitter signal transmission data acquisition unit. The power fluctuation impact data includes transmitter interference signal data and transmitter signal transmission data; collecting interference signal data is used to analyze the impact of the external environment on the transmitter signal, and signal transmission data is used to evaluate the performance of the transmitter itself, and is applicable to the power control of various broadcast transmitters.

[0058] In a possible design, the transmitter signal data acquisition module is specifically:

[0059] Transmitter interference signal data acquisition unit: By installing a power sensor at the output end of the power amplifier of the broadcast transmitter, collect the transmitter transmission power of each monitoring sub-period of the signal transmission time of the target broadcast transmitter, marked as gs i , by installing an electromagnetic environment monitoring sensor on the broadcast transmitter, collect the electromagnetic interference signal frequency and electromagnetic interference signal amplitude of each monitoring sub-period of the signal transmission time of the target broadcast transmitter, marked as gp i , gf i , where i = 1, 2,... n, and i represents the number of the i-th monitoring sub-period;

[0060] Transmitter signal transmission data acquisition unit: Collect the antenna height, signal transceiver node transmission distance, and the highest height of obstacles in the signal propagation range of each monitoring sub-period of the signal transmission time of the target broadcast transmitter, marked as ct i , cj i , ch i .

[0061] The transmitter signal interference intensity data analysis module: It is used to receive the power fluctuation influence data transmitted by the transmitter signal data acquisition module, and calculate the transmitter signal interference intensity index for each monitoring sub-period of the signal transmission time of the target broadcast transmitter according to the transmitter interference signal data collected by the transmitter interference signal data acquisition unit; by calculating the transmitter signal interference intensity index, the interference intensity of different monitoring sub-periods is quantified.

[0062] In a possible design, the calculation formula of the transmitter signal interference intensity index is:

[0063]

[0064] where, α i represents the transmitter signal interference intensity index of the i-th monitoring sub-period, gs i represents the transmitter power of the i-th monitoring sub-period, gp i represents the electromagnetic interference signal frequency of the i-th monitoring sub-period, gf i represents the electromagnetic interference signal amplitude of the i-th monitoring sub-period, and λ1 represents the weight of the electromagnetic interference signal frequency;

[0065] Specifically, the greater the electromagnetic interference signal frequency and the electromagnetic interference signal amplitude, the greater the interference intensity on the broadcast transmitter. Multiplying the two parameters represents the comprehensive influence degree of the electromagnetic interference signal. The transmitter signal interference intensity index is proportional to the comprehensive influence degree of the electromagnetic interference signal. Dividing the comprehensive influence degree of the electromagnetic interference signal by the transmitter power gives a relative quantization value of the interference intensity. The greater the transmitter power, the relatively stronger the ability to resist interference, and the transmitter signal interference intensity index is inversely proportional to the transmitter power.

[0066] In this embodiment, it should be specifically noted that the weight of the electromagnetic interference signal frequency is specifically:

[0067] S01: Obtain the transmitter operating frequency of the target broadcast transmitter, marked as P0;

[0068] S02: The calculation formula of the weight of the electromagnetic interference signal frequency is:

[0069]

[0070] where, λ1 represents the weight of the electromagnetic interference signal frequency, gp i represents the electromagnetic interference signal frequency of the i-th monitoring sub-period, P0 represents the transmitter operating frequency, and x represents a very small positive number used to avoid the denominator being zero;

[0071] When the frequency of the electromagnetic interference signal is closer to the operating frequency of the transmitter, the difference is smaller, indicating that the electromagnetic interference signal has a greater impact on the broadcast transmitter signal, resulting in a greater frequency weight. Conversely, it indicates that the electromagnetic interference signal has a smaller impact on the broadcast transmitter signal and a smaller frequency weight.

[0072] The transmitter signal transmission performance analysis module: is used to receive the power fluctuation impact data transmitted by the transmitter signal data acquisition module, and calculate the transmitter signal transmission loss index for each monitoring sub-period of the signal transmission time of the target broadcast transmitter according to the transmitter signal transmission data collected by the transmitter signal transmission data acquisition unit; which is conducive to comprehensively evaluating the loss situation in the signal transmission process and providing a basis for optimizing the transmission power.

[0073] In a possible design, the transmitter signal transmission performance analysis module is specifically:

[0074] S01: Calculate the transmitter emission signal strength for each monitoring sub-period of the signal transmission time of the target broadcast transmitter through the transmitter emission power and the transmission distance between the signal transceiver nodes:

[0075] ω i =gs i -ε*lgcj i

[0076] Where ω i represents the transmitter emission signal strength for the i-th monitoring sub-period, gs i represents the transmitter emission power for the i-th monitoring sub-period, cj i represents the transmission distance between the signal transceiver nodes for the i-th monitoring sub-period, and ε represents the influence factor of the transmission distance between the signal transceiver nodes;

[0077] Specifically, when the value of the transmission distance between the signal transceiver nodes remains unchanged, the transmitter emission signal strength is an increasing function of the transmitter emission power, and the transmitter emission signal strength is proportional to the transmitter emission power;

[0078] S02: The calculation formula for the transmitter signal transmission loss index is:

[0079]

[0080] Where β i represents the transmitter signal transmission loss index for the i-th monitoring sub-period, ω i represents the transmitter emission signal strength for the i-th monitoring sub-period, ω 预 represents the preset transmitter emission signal strength, ct i represents the antenna height for the i-th monitoring sub-period, ch iDenote the highest height of obstacles in the signal propagation range for the \(i\)-th monitoring sub-period.

[0081] Specifically, for This formula intuitively reflects the loss ratio during signal transmission by comparing the difference between the actual signal intensity transmitted by the transmitter and the preset signal intensity of the transmitter. The larger the value, the more severe the loss of the transmitter signal during transmission, and the worse the signal transmission effect. Conversely, it indicates that the loss of the transmitter signal during transmission is lighter, and the signal transmission effect is better.

[0082] When the highest height of obstacles in the signal propagation range is higher, the transmitter signal is more affected by occlusion and reflection, and the signal transmission effect is worse. Conversely, the transmitter signal is less affected by occlusion and reflection, and the signal transmission effect is better.

[0083] The transmitter transmission power stability evaluation module: is used to calculate the transmitter transmission power stability coefficient for each monitoring sub-period of the signal transmission time of the target broadcast transmitter based on the transmitter signal interference intensity index and the transmitter signal transmission loss index for each monitoring sub-period of the signal transmission time of the target broadcast transmitter; comprehensively reflects the stability degree of the transmission power for each monitoring sub-period, which is conducive to timely detecting abnormal power fluctuations, thereby providing key data support for optimizing the transmission power.

[0084] In a possible design, the transmitter transmission power stability coefficient is specifically:

[0085]

[0086] Where, \(\theta\) i Denotes the transmitter transmission power stability coefficient for the \(i\)-th monitoring sub-period, \(\alpha\) i Denotes the transmitter signal interference intensity index for the \(i\)-th monitoring sub-period, \(\alpha\) i-1 Denotes the transmitter signal interference intensity index for the \((i - 1)\)-th monitoring sub-period, \(\beta\) i Denotes the transmitter signal transmission loss index for the \(i\)-th monitoring sub-period, \(\beta\) i-1 Denotes the transmitter signal transmission loss index for the \((i - 1)\)-th monitoring sub-period, \(\Delta\alpha\) denotes the mean value of the transmitter signal interference intensity index, \(\Delta\beta\) denotes the mean value of the transmitter signal transmission loss index, \(n\) denotes the number of monitoring sub-periods.

[0087] The transmitter transmission power control module: obtains the transmitter transmission power stability coefficients for each monitoring sub-period of the signal transmission time of the target broadcast transmitter, compares them with the preset transmitter transmission power stability coefficients, and adjusts the transmission power; by monitoring and evaluating the transmitter transmission power stability coefficients in real time, adjusts the control strategy according to the feedback results to improve the accuracy and stability of the control.

[0088] In a possible design, the transmitter transmission power control module is specifically:

[0089] Obtains the transmitter transmission power stability coefficients for each monitoring sub-period of the signal transmission time of the target broadcast transmitter, compares them with the preset transmitter transmission power stability coefficients. If the transmitter transmission power stability coefficient of a certain monitoring sub-period is greater than the preset transmitter transmission power stability coefficient, it indicates that there are abnormal fluctuations in the transmitter transmission power during this period, and the transmission power of the broadcast transmitter should be adjusted. Otherwise, it indicates that there are no abnormal fluctuations in the transmitter transmission power during this period.

[0090] The transmitter transmission power control effect evaluation module: is used to obtain in real time the transmission power value after the transmission power of the broadcast transmitter is adjusted, calculate the power adjustment effect index of the broadcast transmitter, and analyze the effectiveness of the regulation measures; is conducive to comprehensively evaluating the effect of the transmitter transmission power adjustment and ensuring that the signal quality, coverage range, and anti-interference ability of the broadcast transmitter reach the optimal state.

[0091] In this embodiment, it should be specifically noted that the transmitter transmission power control effect evaluation module is specifically:

[0092] S01: Record the transmitter transmission power and the signal transceiver node transmission distance before the transmission power of the broadcast transmitter is adjusted, denoted as the current transmission power and the current signal transceiver node transmission distance, and obtain in real time the transmitter transmission power and the signal transceiver node transmission distance after the adjustment, denoted as the new transmission power and the new signal transceiver node transmission distance;

[0093] S02: The calculation formula for the power adjustment effect index is:

[0094]

[0095] Where, is denoted as the power adjustment effect index, gs after is denoted as the new transmission power, gs before is denoted as the current transmission power, cj after is denoted as the new signal transceiver node transmission distance, cj before is denoted as the current signal transceiver node transmission distance, ε is denoted as the influence factor of the signal transceiver node transmission distance;

[0096] S03: Obtain the power adjustment effect index of the broadcast transmitter in real time. If it indicates that the signal intensity of the transmitter increases and the signal propagation range of the transmitter expands, then the effect after the transmission power adjustment of the broadcast transmitter is significant. If it indicates that the signal intensity of the transmitter decreases and the signal propagation range of the transmitter shrinks, then the effect after the transmission power adjustment of the broadcast transmitter is poor, and the control effect of the transmission power of the transmitter is fed back to the management personnel of the control center for processing.

[0097] The present invention provides another embodiment, which is as follows:

[0098] S01: A certain broadcast transmitter performs transmission power adjustment within a certain time period, and records the transmission power gs of the transmitter before adjustment before = 1000W, the transmission distance cj of the signal transceiver node before = 10km, records the transmission power gs of the transmitter after adjustment after = 1200W, the transmission distance cj of the signal transceiver node after = 10km, the influence factor ε of the transmission distance of the signal transceiver node = 0.1;

[0099] S02: Calculate the power adjustment effect index:

[0100]

[0101] S03: Since 40 > 0, it indicates that the signal intensity of the transmitter increases and the signal propagation range of the transmitter expands, then the effect after the transmission power adjustment of the broadcast transmitter is significant.

[0102] Please refer to Figure 3 As shown, the present invention provides a method for controlling the transmission power of a broadcast transmitter based on big data, including the following steps:

[0103] Step S01: Division of the signal transmission time of the transmitter: used to divide the signal transmission time of the target broadcast transmitter into n monitoring sub-periods according to equal time;

[0104] Step S02: Acquisition of transmitter signal data: used to acquire the power fluctuation influence data of each monitoring sub-period of the signal transmission time of the target broadcast transmitter. The step S02: Acquisition of transmitter signal data includes a sub-step of acquiring transmitter interference signal data and a sub-step of acquiring transmitter signal transmission data.

[0107] Step S05: Evaluation of the stability of the transmitter's transmission power: It is used to calculate the transmitter's transmission power stability coefficient for each monitoring sub-period of the signal transmission time of the target broadcast transmitter according to the transmitter signal interference intensity index and the transmitter signal transmission loss index for each monitoring sub-period of the signal transmission time of the target broadcast transmitter;

[0108] Step S06: Control of the transmitter's transmission power: Obtain the transmitter's transmission power stability coefficient for each monitoring sub-period of the signal transmission time of the target broadcast transmitter, compare it with the preset transmitter's transmission power stability coefficient, and adjust the transmission power;

[0110] In this embodiment, it should be specifically noted that the present invention collects the power fluctuation influence data of each monitoring sub-period of the signal transmission time of the target broadcast transmitter, calculates the transmitter signal interference intensity index of each monitoring sub-period of the signal transmission time of the target broadcast transmitter according to the transmitter interference signal data collected by the transmitter interference signal data acquisition unit, calculates the transmitter signal transmission loss index of each monitoring sub-period of the signal transmission time of the target broadcast transmitter according to the transmitter signal transmission data collected by the transmitter signal transmission data acquisition unit, further calculates the transmitter transmission power stability coefficient of each monitoring sub-period of the signal transmission time of the target broadcast transmitter, and compares it with the preset transmitter transmission power stability coefficient. If the transmitter transmission power stability coefficient of a certain monitoring sub-period is greater than the preset transmitter transmission power stability coefficient, it indicates that there is abnormal fluctuation in the transmitter transmission power of this period, and the transmission power of the broadcast transmitter should be adjusted. Otherwise, it indicates that there is no abnormal fluctuation in the transmitter transmission power of this period. The collected interference signal data is used to analyze the influence of the external environment on the transmitter signal, and the signal transmission data is used to evaluate the performance of the transmitter itself. It is applicable to the power control of various broadcast transmitters. By calculating the transmitter signal interference intensity index, the interference intensity of different monitoring sub-periods is quantified. By comprehensively evaluating the loss situation in the signal transmission process, it provides a basis for optimizing the transmission power. Through the transmitter transmission power stability coefficient, the stability degree of the transmission power of each monitoring sub-period is comprehensively reflected, which is conducive to timely discovering abnormal power fluctuations, and then adjusting the transmitter transmission power control strategy according to the feedback results to improve the accuracy and stability of power control.

[0111] The present invention utilizes the transmitter transmission power control effect evaluation module to record in real time the transmitter transmission power and the transmission distance between the signal transceiver nodes before adjusting the transmission power of the broadcast transmitter, obtains the transmitter transmission power and the transmission distance between the signal transceiver nodes after adjustment, thereby calculates the power adjustment effect index of the broadcast transmitter, and analyzes the effectiveness of the regulation measures.
