Description

Technical Field

[0001] The present invention belongs to the technical field of shortwave radio control, and particularly relates to a remote control method for foreign trade shortwave radios based on a WiFi link. Background Art

[0002] As a core device for international broadcasting, ocean communication, and disaster emergency, shortwave radios have irreplaceable advantages in foreign trade scenarios. Shortwave signals can achieve global coverage through ionospheric reflection, especially suitable for scenarios lacking infrastructure such as ocean navigation and communication in remote areas. In war or natural disasters, shortwave communication does not rely on ground network hubs and becomes a key communication means. Compared with satellite communication, the operating cost of shortwave radios is lower, suitable for long-term foreign trade communication needs.

[0003] With its advantages, WiFi technology has gradually become the mainstream solution in the field of remote control. Compared with Bluetooth (<15m) or infrared (<10m), WiFi supports transmission distances of up to hundreds of meters, has strong penetration, and can adapt to complex environments. It supports concurrent connection of multiple devices, facilitating the integration of the Internet of Things and smart home systems. The popularity of WiFi modules is high, and the development cost is lower than that of optical fibers or dedicated wireless protocols.

[0004] The operating quality of shortwave radios is extremely vulnerable to environmental factors, which not only affect the transmission quality of radio signals but may also cause problems such as frequent restarting of the device, communication interruption, and frequency drift. Traditional control systems are mostly local mechanical or analog controls, lacking the ability to dynamically perceive and remotely adjust the above complex working conditions. The communication quality is not only related to the operating frequency, transmission power, and modulation method of the device itself but also closely related to the current working state of the device. It cannot be accurately evaluated through simple rules, not only not suitable for rapid switching and remote deployment in complex foreign trade scenarios but also not conducive to batch remote centralized management. Summary of the Invention

[0074] Thirdly, the present invention is described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present invention in detail, for the sake of explanation, the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein.

[0075] Please refer to the attached Figure 1 As shown, a remote control method for a foreign trade shortwave radio based on a WiFi link is provided, including:

[0076] S1. Establish a WiFi communication link between the remote control terminal and the shortwave radio;

[0077] S2. Obtain the device status data of the shortwave radio. The device status data includes working frequency information, signal strength information, and standing wave ratio information. Obtain the abnormal working state of the shortwave radio according to the signal strength information and the standing wave ratio information, and obtain the device status information according to the device status data;

[0078] S3. Obtain the working environment data of the shortwave radio. The working environment data includes ambient temperature information, power supply stability information, and signal interference information. Obtain the environmental interference coefficient according to the ambient temperature information and the signal interference information, and obtain the power supply compensation value according to the power supply stability information;

[0079] S4. Obtain the communication status data of the shortwave radio. The communication status data includes transmission power information and modulation mode information. Obtain the communication compensation information according to the communication status data;

[0080] S5. Obtain the control strategy according to the device status information, environmental interference coefficient, power supply compensation value, and communication compensation information, and control the shortwave radio according to the control strategy;

[0081] S6. Obtain the device response characteristic information and environmental interference attenuation information after controlling the shortwave radio according to the control strategy instruction, obtain the optimization information according to the device response characteristic information and the environmental interference attenuation information, re-obtain the control strategy, and generate a joint control strategy in combination with the optimization information until the preset conditions are met.

[0082] In the above steps S1 to S6, the remote control terminal (such as an industrial control computer or an embedded single board) is paired with the WiFi interface of the shortwave radio through the WiFi module to form a two-way data transmission channel. This link is used not only to send control instructions but also to obtain the radio operation and environmental data in real time. Key parameters such as the working frequency, signal strength, and standing wave ratio inside the shortwave radio are periodically read through the WiFi link. Combining the signal strength and standing wave ratio, it is determined whether the shortwave radio is in an abnormal working state, and the "device status information" is integrated based on the working frequency, signal strength, and standing wave ratio and reported to the control end. The ambient temperature, power supply stability (voltage / current fluctuations), and signal interference information are collected. The "environmental interference coefficient" is calculated based on the ambient temperature and signal interference to evaluate the impact of high temperature or strong interference on the transmission performance. The "power supply compensation value" is generated according to the power supply stability. The transmission power setting and the current modulation mode (such as USB, LSB, CW, etc.) are obtained, and the "communication compensation information" is calculated to optimize the power output and modulation depth. The control end synthesizes the "device status information", "environmental interference coefficient", "power supply compensation value", and "communication compensation information", generates the optimal control strategy through the preset control algorithm, and sends the adjustment instructions in real time through the WiFi link to dynamically control the frequency, power, and modulation mode of the radio. After executing the control instructions, it continues to monitor the radio response (including the output waveform characteristics) and the attenuation of environmental interference, and uses this as input to calculate the "optimization information" and iteratively update the control strategy to achieve joint multi-factor coordinated adjustment until all indicators meet the preset reliability and signal quality thresholds. Through multiple rounds of data feedback and strategy optimization, the frequency offset, power shortage, or overload problems are automatically corrected, effectively reducing the signal distortion and interruption rate, ensuring the high reliability of the communication link. Based on the real-time calculation of the environmental interference coefficient and communication compensation information, the transmission power can be dynamically increased or a more suitable modulation mode can be switched, thereby reducing the impact of electromagnetic noise on the signal and ensuring the data transmission quality. Through the dynamic control strategy, it can be flexibly adjusted according to different communication distances, bandwidth requirements, or frequency band limitations to meet the rapid deployment and switching needs of the foreign trade shortwave radio in multiple scenarios.

[0083] In a preferred embodiment, the steps of obtaining the device status data of the shortwave radio, where the device status data includes working frequency information, signal strength information, and standing wave ratio information, and obtaining the abnormal working state of the shortwave radio according to the signal strength information and the standing wave ratio information, and obtaining the device status information according to the device status data, include:

[0084] S201. Obtain the device status data of the shortwave radio, where the device status data includes working frequency information, signal strength information, and standing wave ratio information;

[0085] S202. Obtain the corresponding signal strength vector and standing wave ratio vector according to the signal strength information and the standing wave ratio information respectively;

[0086] S203. Obtain the working state value according to the signal strength vector and the standing wave ratio vector;

[0087] S204. Obtain the working state threshold;

[0088] S205. Determine whether the working state value exceeds the working state threshold;

[0089] If the working state value exceeds the working state threshold, it is determined that the shortwave radio is working abnormally and marked as an abnormal working state;

[0090] If the working state value does not exceed the working state threshold, it is determined that the shortwave radio is working normally;

[0091] S206. Obtain the device state information according to the device state data.

[0092] In the above steps S201 to S206, the current working frequency information, signal strength information and standing wave ratio information of the shortwave radio are collected through the WiFi link to form complete device state data. The signal strength and standing wave ratio information are processed to form a signal strength vector and a standing wave ratio vector respectively. According to the signal strength vector and the standing wave ratio vector, the working state value is calculated. The calculation formula of the working state value is , where G represents the working state value, Q represents the signal strength vector, K represents the standing wave ratio vector. A working state threshold is preset to divide the "normal / abnormal" state boundary. Compare the current working state value with the threshold. If the state value exceeds the threshold, it indicates that there are abnormal fluctuations in the device (such as signal attenuation, reflection enhancement, etc.), and it is determined as an abnormal working state. If the state value does not exceed the threshold, it indicates that the device is in a reasonable working condition and is determined as a normal state. The unified device state information is generated according to the working frequency information, signal strength information and standing wave ratio information for the subsequent control strategy module to use. The traditional manual monitoring is transformed into system automatic judgment. Through the quantization and fusion of signals and standing wave ratios, the high-precision recognition of the operating state is realized. Based on the configurable working state threshold setting, it can flexibly adapt to the working characteristics of different models of shortwave radios and achieve high-adaptability abnormal detection.

[0093] In a preferred embodiment, the step of obtaining the device state information according to the device state data includes:

[0094] S2061. Obtain the corresponding working frequency vector according to the working frequency information;

[0095] S2062. Obtain the device state value according to the working frequency vector, the signal strength vector and the standing wave ratio vector;

[0096] S2063. Obtain the device state table, where the device state table includes multiple device state intervals and the device state information corresponding to each device state interval;

[0097] S2064. Obtain the corresponding device status information from the device status table according to the device status range corresponding to the device status value.

[0098] In the above steps S2061 to S2064, the working frequency information of the shortwave radio is collected and sorted in time sequence to form a working frequency vector, which is used to reflect the frequency change trend and stability characteristics of the radio within a certain time range. The generated working frequency vector is jointly processed with the previously obtained signal strength vector and standing wave ratio vector, and a comprehensive device status value is calculated. The calculation formula of the device status value is , where S represents the device status value, P represents the working frequency vector, Q represents the signal strength vector, K represents the standing wave ratio vector. Multiple device status ranges are predefined in the device status table, and each range corresponds to different descriptions of operating conditions (such as "normal operation", "slight abnormality", "severe abnormality", "needs maintenance", etc.). Each range is constructed based on a large amount of actual operation data or empirical rules, and has good adaptability and stability. The calculated device status value is matched with the ranges in the device status table, and the device status information corresponding to the device status range where the current status value is located is obtained by looking up the table, so as to realize the automatic identification and marking of the device operating conditions. The core performance indicators such as working frequency, signal strength, and standing wave ratio are comprehensively processed, avoiding misjudgment that may be caused by a single parameter, making the status evaluation more scientific and comprehensive. Using the device status table to realize look-up table type status identification, avoiding repeated calculations or manual judgments, with a fast response speed, and is suitable for real-time monitoring and rapid warning scenarios.

[0099] In a preferred embodiment, the steps of obtaining the working environment data of the shortwave radio, where the working environment data includes environmental temperature information, power supply stability information, and signal interference information, and obtaining the environmental interference coefficient according to the environmental temperature information and the signal interference information, and obtaining the power supply compensation value according to the power supply stability information, include:

[0100] S301. Obtain the working environment data of the shortwave radio, where the working environment data includes environmental temperature information, signal strength information, and signal interference information;

[0101] S302. Obtain the corresponding environmental temperature vector and multiple signal interference vectors according to the environmental temperature information and the signal interference information respectively;

[0102] S303. Obtain the corresponding environmental interference coefficient according to the environmental temperature vector and the multiple signal interference vectors;

[0103] S304. Obtain the power supply compensation value according to the power supply stability information.

[0104] In the above steps S301 to S304, the ambient temperature information, signal interference information, and power supply stability information of the short-wave radio are obtained periodically or on demand through the WiFi link. The ambient temperature information reflects the temperature changes of the device shell and internal electronic components, which has a direct impact on the transmission power and modulation characteristics. The signal interference information can come from surrounding radio noise, adjacent frequency radio interference, or other electromagnetic sources. The power supply stability information includes indicators such as input voltage fluctuations, frequency deviations, and momentary power outages. Organize the ambient temperature information into an ambient temperature vector according to the sampling time sequence to reflect the temperature change trend of the short-wave radio at consecutive moments. Construct real-time measurement values of multiple signal interference sources (such as atmospheric noise, adjacent frequency leakage, radiation from surrounding devices, etc.) into multiple signal interference vectors respectively. According to the ambient temperature vector and each signal interference vector, calculate the ambient interference coefficient. The calculation formula of the ambient interference coefficient is , where J represents the ambient interference coefficient, H represents the ambient temperature vector, i represents the number of multiple signal interference vectors, i = 1, 2, 3... n, represents the i-th signal interference vector. According to the voltage deviation rate, frequency stability, and transient fluctuation characteristics in the power supply stability information, obtain a power supply compensation value. By real-time quantification of the ambient temperature and multi-source electromagnetic interference, the comprehensive impact of external factors on the signal can be accurately evaluated, and targeted compensation can be carried out, significantly enhancing the communication stability in complex environments. The ambient interference coefficient and the power supply compensation value can be dynamically updated according to the changes in the field conditions to achieve online adaptive adjustment of transmission parameters (such as power, modulation mode, filter bandwidth, etc.) and avoid manual intervention.

[0105] In a preferred embodiment, the steps of obtaining the power supply compensation value according to the power supply stability information include:

[0106] S3041. Obtain the corresponding power supply stability value according to the power supply stability information;

[0107] S3042. Obtain a power supply compensation table, where the power supply compensation table includes multiple power supply stability intervals and the corresponding power supply compensation values for each power supply stability interval;

[0108] S3043. Obtain the corresponding power supply compensation value from the power supply compensation table according to the power supply stability interval corresponding to the power supply stability value.

[0109] In the above steps S3041 to S3043, the current power supply stability information (such as voltage deviation, frequency drift, transient fluctuation, etc.) is read from a preset real-time monitoring module. After preprocessing, a standardized power supply stability value is obtained. A power supply compensation table is pre-established in the controller. The table is divided into several levels according to the "power supply stability interval", and each interval corresponds to a power supply compensation value (which can be power gain, modulation depth adjustment amount, etc.), and can be flexibly configured according to the device model and application scenario. The real-time power supply stability value is matched with each interval in the compensation table. Once the interval to which it belongs is found, the compensation value corresponding to this interval can be directly queried and obtained. Only one simple interval matching and table lookup are required, without complex algorithms or large-scale operations, ensuring that the compensation value can be obtained within milliseconds. The table mapping method has a simple logic, and troubleshooting and debugging are intuitive, ensuring a stable and controllable compensation response even under extreme power fluctuations.

[0110] In a preferred embodiment, communication status data of a shortwave radio is obtained, wherein the communication status data includes transmission power information and modulation mode information. The steps of obtaining communication compensation information according to the communication status data include:

[0111] S401. Obtain the communication status data of the shortwave radio, wherein the communication status data includes transmission power information and modulation mode information;

[0112] S402. Obtain the corresponding transmission power vector and modulation mode vector according to the transmission power information and modulation mode information;

[0113] S403. Obtain the communication compensation value according to the transmission power vector and modulation mode vector;

[0114] S404. Obtain the communication compensation table, wherein the communication compensation table includes a plurality of communication compensation intervals and the communication compensation information corresponding to each communication compensation interval;

[0115] S405. Obtain the corresponding communication compensation information from the communication compensation table according to the communication compensation interval corresponding to the communication compensation value.

[0116] In the above steps S401 to S405, the transmission power information and modulation mode information of the shortwave radio are collected in real time. The transmission power information is constructed as a transmission power vector, which can describe the power change trend, stability, etc. The modulation mode information is converted into a modulation mode vector. For example, different modulation techniques (AM, SSB, PSK, etc.) are mapped into a standardized vector. Combining the transmission power vector and the modulation mode vector, the communication compensation value is calculated. The calculation formula of the communication compensation value is In the formula, T represents the communication compensation value, F represents the transmit power vector, and Z represents the modulation mode vector. The built-in communication compensation table is called, which is divided into several communication compensation intervals according to the compensation value interval. Each interval corresponds to specific communication compensation information, such as signal gain adjustment amount, modulation depth adjustment strategy, channel fault tolerance configuration, etc. The communication compensation value is matched with the communication compensation table to find the corresponding compensation interval, and the corresponding communication compensation information is extracted based on this. Based on the joint calculation of transmit power and modulation mode, the performance gap in different communication scenarios is accurately reflected, and compensation suggestions are dynamically generated to effectively improve link stability and signal quality. The introduction of communication compensation information can adjust the power, modulation strategy or coding parameters as needed, thereby automatically adapting to complex electromagnetic environments and variable workloads.

[0121] S504: Obtain a corresponding control strategy from the strategy table according to the radio control interval corresponding to the radio control value, and control the shortwave radio station according to the control strategy.

[0122] As in steps S501 to S504 above, the device status value is extracted from the device status information, the communication compensation value is extracted from the communication compensation information, and a radio control value is calculated by combining the device status value, the environmental interference coefficient, the power supply compensation value, and the communication compensation value. The calculation formula of the radio control value is: , where D represents the radio control value, S represents the device status value, J represents the environmental interference coefficient, C represents the power supply compensation value, T represents the communication compensation value, which is used to reflect the total demand level of the shortwave radio control strategy under the current state. Call the preset strategy table, which contains multiple radio control intervals (such as divided by the range of the radio control value), and configure corresponding control strategies for each interval (such as transmit power adjustment, frequency hopping, modulation mode switching, antenna adjustment instructions, etc.). According to the control interval to which the radio control value belongs, find the corresponding control strategy in the strategy table, issue the control strategy, and remotely adjust the relevant parameters of the shortwave radio through the WiFi link to achieve remote precise control. Comprehensively consider the state indicators of multiple aspects such as equipment, environment, power supply, and communication, construct a unified control value, and the control strategy is dynamically obtained according to the current multi-parameter state to avoid the failure of static settings and improve the response ability to sudden situations and abnormal scenarios.

[0130] If the control state value does not exceed the control state threshold, it is determined that the device transmission is normal after the shortwave radio executes the control strategy.

[0131] S606. Re-obtain the control strategy, and generate a joint control strategy in combination with the optimization information until the preset conditions are met.

[0132] In the above steps S601 to S606, after the control strategy is issued and executed, obtain, via the WiFi link, device response characteristic information (such as radio response delay, transmitted signal stability, modulation response matching degree, etc.) and environmental interference attenuation information (such as the comparison value of interference intensity before and after the execution of the control strategy, improvement of temperature fluctuation, etc.). Convert the obtained data into a device response characteristic vector and an environmental interference attenuation vector. Combine the above two vectors to calculate a control state value. The calculation formula of the control state value is , where L represents the control state value, Y represents the device response characteristic vector, and W represents the environmental interference attenuation vector. This value represents the actual execution effect of the current control strategy. Set a control state threshold as the evaluation benchmark. If the control state value exceeds the threshold, it indicates abnormal control and unsatisfactory control effect (such as abnormal device response, no obvious improvement in environmental interference, etc.). Then mark the control state value as optimization information. If the control state value does not exceed the threshold, it is considered that the shortwave radio is working in a normal state and the strategy can remain unchanged. When the control is abnormal, recalculate and generate a new combined control strategy by jointly calculating a control strategy and optimization information according to the previous method. The optimization directions include but are not limited to adjusting the transmission power, modifying the modulation method, changing the frequency range, adding environmental noise suppression instructions, etc. Iteratively execute the above process until the device operating state and interference control effect meet the preset conditions (such as the bit error rate is lower than a certain value within a stable time period, the temperature fluctuation range is less than a certain threshold, etc.), and finally form a stable and reliable control loop. Compared with the traditional single execution strategy, through continuous monitoring and feedback analysis, it is possible to achieve full-link closed-loop control of strategy → execution → evaluation → optimization → re-execution. For different environmental noises, power supply fluctuations, and device state differences, the control strategy can be dynamically adjusted to enhance the adaptability of the control system to external disturbances. Through environmental interference attenuation analysis and device response evaluation, precise adjustment is performed on control dimensions such as power, frequency, and modulation method to optimize the transmission rate and communication clarity.

[0133] In a preferred embodiment, the steps of re-obtaining the control strategy and generating a combined control strategy in combination with the optimization information until the preset conditions are met include:

[0134] S6061. After obtaining the optimization information, return to the step of obtaining the device state data of the shortwave radio to obtaining the control strategy according to the device state information, environmental interference coefficient, power supply compensation value, and communication compensation information. Re-obtain a new control strategy, and obtain the corresponding radio control value according to the new control strategy, and mark it as the optimized radio control value;

[0135] S6062. Obtain the combined strategy value according to the control state value corresponding to the optimization information and the optimized radio control value;

[0136] S6063. Obtain a combined table, where the combined table includes multiple combined policy intervals and the corresponding combined control policies for each combined policy interval;

[0137] S6064. Obtain the corresponding combined control policy from the combined table according to the combined policy interval corresponding to the combined policy value, and control the shortwave radio according to the combined control policy;

[0138] S6065. Obtain the control status value after controlling the shortwave radio according to the combined control policy, and re-judge the device transmission status of the shortwave radio according to the control status value until the device transmission is normal.

[0139] In the above steps S6061 to S6065, when an abnormality occurs after the original control policy is executed (that is, the control status value exceeds the threshold), the optimization information is fed back to the previous policy generation process, and the latest device status information, environmental interference coefficient, power supply compensation value, and communication compensation information are collected again. Based on these updated data, a new control policy is generated, and the control value corresponding to this policy is obtained and marked as the "optimized radio control value". According to the control status value recorded in the optimization information and the latest obtained "optimized radio control value", a combined policy value is calculated. The calculation formula of the combined policy value is , where V represents the combined policy value, L represents the control status value, represents the optimized radio control value. The preset combined table is a policy mapping table, including multiple combined policy intervals corresponding to combined policy values, and the combined control policies mapped by each interval (which may include multi-parameter control configurations such as frequency switching, transmit power curve adjustment, modulation mode switching, etc.). According to the interval where the combined policy value is located, the corresponding combined control policy is obtained, and the combined control policy is executed to control the shortwave radio, which may include combined regulation of multiple aspects such as the hardware working mode, signal parameters, and interference avoidance. After the combined control policy is executed, the current control status value of the shortwave radio is obtained again, and it is judged whether this status value meets the preset stability standard. If it meets, the adjustment process is terminated and the control policy converges. If it does not meet, the combined control policy is obtained again and the iteration continues, forming a closed-loop process of multi-round optimization + combined control. The control policy can be continuously iterated according to the device operation feedback, forming a self-learning and adaptive mechanism to adapt to dynamic environmental interference, power fluctuations, or modulation states, especially suitable for the regulation of shortwave radios in extreme or variable electromagnetic environments (such as the wild, wartime, emergency communication, etc.), effectively ensuring the stability and continuity of the communication link. The combined control policy integrates control anomalies and current state data to generate a more robust and reparable control scheme, reducing the risk of single policy failure. The mechanism of control execution and feedback analysis completely constructs a closed-loop control system, greatly improving the policy accuracy and system response speed.

[0141] One or more processors;

[0143] When the one or more programs are executed by the one or more processors, the one or more processors implement a remote control method for foreign trade shortwave radio based on WiFi link.

[0144] It should be noted that, as shown in the attached Figure 2 The shortwave radio mainly includes a front panel module, a main control module, a power amplifier module, an antenna tuner module, and a power processing module, etc. The transceiver both adopts a zero-IF scheme. When receiving, the received RF signal is directly A / D sampled after passing through the antenna tuner matching network, filter, and low-noise amplifier, down-converted to a baseband signal and then sent to the processor for demodulation. The demodulated audio signal is sent to the front panel for audio amplification. When transmitting, the front panel amplifies the transmitted audio signal and sends it to the main control. The main control up-converts the modulated baseband signal to be transmitted and then converts it to an RF signal through D / A conversion, and then amplifies it through the power amplifier, filters out harmonics, and matches it to the antenna through the antenna tuner network for transmission. The specific working mode will not be elaborated here too much.
