Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle remote control signal amplifier. Background Art

[0002] In the field of drone technology, the transmission quality of remote control signals is crucial to the control of drones. Traditional drone remote control systems usually rely on wireless signals for communication, which are easily affected by environmental factors such as obstacles and electromagnetic interference, resulting in signal attenuation or distortion. In order to improve the stability and distance of signal transmission, a variety of signal amplifiers have appeared on the market, but they often have problems such as fixed gain, inability to adapt to different signal strengths, and lack of real-time monitoring and adjustment mechanisms. These problems limit the application capabilities of drones in complex environments, especially in long distances or places with many obstacles. Therefore, the development of a drone remote control signal amplifier that can automatically adjust the gain, monitor the signal quality in real time, and has a self-protection mechanism is of great significance to improving the reliability and safety of drone control. Summary of the invention

[0003] The purpose of the invention is to provide a drone remote control signal amplifier.

[0004] To achieve the above object, the present invention is implemented according to the following technical solutions:

[0005] The present invention comprises an input antenna, a filter, a signal amplifier, an output antenna, an automatic gain controller and a control and monitoring module. The signal output end of the input antenna is connected to the filter, the control signal transmission end of the filter is connected to the automatic gain controller, the signal output end of the filter is connected to the signal amplifier, the data transmission end of the signal amplifier is connected to the control and monitoring module, and the signal output end of the signal amplifier is connected to the output antenna.

[0006] The input antenna receives the signal sent by the drone remote control, the filter is used to filter out noise signals in other frequency bands to ensure the purity of the input signal, the signal amplifier amplifies the input signal to increase the signal strength, the output antenna transmits the amplified signal to the drone, the automatic gain controller controls the signal gain to adapt to input signals of different strengths, and the control and monitoring module monitors parameters such as signal strength and chip temperature in real time to control the amplification gain.

[0007] The control method of the automatic gain controller comprises the following steps:

[0008] S1: The signal detection circuit built into the AGC module collects the strength of the input signal in real time and transmits the collected signal strength value to the control chip;

[0009] S2: Set the threshold range of signal strength, and the control chip determines whether the current signal strength is within the threshold range;

[0010] S3: If the signal strength is low: increase the gain to amplify the weak signal; if the signal strength is high: reduce the gain to avoid signal saturation and distortion;

[0011] S4: Collect the adjusted signal strength. If the adjusted signal strength is still not within the set range, further adjust the gain value and continuously perform feedback adjustment to ensure that the signal strength is stable within the threshold range.

[0012] S5: If the signal strength is within the set range, lock the current gain value, stop further adjustment, sample the signal strength regularly, and restart the AGC adjustment process if the signal environment changes.

[0013] The control method of the control and monitoring module comprises the following steps:

[0014] S1: The output signal strength of the signal amplifier is collected in real time through the sampling circuit, sampling is performed at fixed intervals, and the signal strength data is transmitted to the main control chip for analysis;

[0015] S2: Monitor the operating temperature of the signal amplifier and control module through the temperature sensor. If the temperature is higher than the set safety range, an alarm signal is triggered and the signal gain is reduced to reduce power consumption and heat generation;

[0016] S3: Detect the voltage and current of the power supply to avoid overcurrent or low voltage. If the power supply voltage is abnormal, immediately reduce the gain of the signal amplifier to reduce power consumption and keep the system stable.

[0017] S4: Compare the real-time collected signal strength and temperature parameters with the set values. If the signal strength is too low, increase the gain of the signal amplifier to maintain the signal quality. If the signal strength is too high or the temperature is too high, reduce the signal gain to prevent the device from overheating or signal distortion.

[0018] S5: When the temperature or power supply voltage exceeds the safety range, an alarm is triggered and gain reduction protection is performed. If the overheating situation persists, the power supply is automatically cut off or the system enters standby mode to ensure system safety.

[0019] S6: Record signal strength, temperature, power supply voltage and other parameters in real time to facilitate fault analysis and system optimization, and transmit data to the host computer or monitoring terminal through wireless or wired communication interface to achieve remote monitoring.

[0020] The beneficial effects of the present invention are:

[0021] The present invention is a drone remote control signal amplifier. Compared with the prior art, the present invention realizes real-time monitoring and adaptive adjustment of signal strength by integrating an automatic gain controller and a control and monitoring module, thereby improving the stability and reliability of signal transmission. The automatic gain controller can automatically adjust the gain according to the strength of the input signal to adapt to the signal transmission requirements under different environmental conditions, avoiding the problem of too weak or too strong signals. The control and monitoring module monitors key parameters such as signal strength and chip temperature in real time, and adjusts or alarms when necessary, ensuring the safe and stable operation of the system. In addition, the amplifier also has a remote monitoring function, which is convenient for users to monitor the status of the equipment in real time and analyze faults, further improving the intelligence level of the system.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0024] like Figure 1 As shown: The present invention includes an input antenna, a filter, a signal amplifier, an output antenna, an automatic gain controller and a control and monitoring module. The signal output end of the input antenna is connected to the filter, the control signal transmission end of the filter is connected to the automatic gain controller, the signal output end of the filter is connected to the signal amplifier, the data transmission end of the signal amplifier is connected to the control and monitoring module, and the signal output end of the signal amplifier is connected to the output antenna.

[0025] The input antenna receives the signal sent by the drone remote control, the filter is used to filter out noise signals in other frequency bands to ensure the purity of the input signal, the signal amplifier amplifies the input signal to increase the signal strength, the output antenna transmits the amplified signal to the drone, the automatic gain controller controls the signal gain to adapt to input signals of different strengths, and the control and monitoring module monitors parameters such as signal strength and chip temperature in real time to control the amplification gain.

[0026] The input antenna is responsible for receiving the signal sent by the drone remote controller. The working principle is to capture the electromagnetic waves in the air and convert them into electrical signals to provide raw input for subsequent signal processing.

[0027] The filter is used to filter out noise signals from other frequency bands to ensure the purity of the input signal. The working principle is to allow signals of specific frequencies to pass through through specific circuit design, while blocking or weakening signals of other frequencies, thereby reducing interference.

[0028] The signal amplifier amplifies the input signal and increases the signal strength. The working principle is to use electronic components (such as transistors) to amplify the signal so that it can be received by the drone at a longer distance.

[0029] The output antenna transmits the amplified signal to the drone. The working principle is to convert the electrical signal back into electromagnetic waves and transmit it to the drone wirelessly.

[0030] The automatic gain controller controls the signal gain to adapt to input signals of different strengths. The working principle is to collect the strength of the input signal in real time through the built-in signal detection circuit, and automatically adjust the gain according to the threshold range of the signal strength to ensure that the signal is transmitted in the best state.

[0031] The control and monitoring module monitors signal strength, chip temperature and other parameters in real time to control the amplification gain. The working principle is to collect data in real time through sampling circuits and temperature sensors, and adjust according to the set safety range to keep the system running stably.

[0032] The control method of the automatic gain controller comprises the following steps:

[0033] S1: The signal detection circuit built into the AGC module collects the strength of the input signal in real time and transmits the collected signal strength value to the control chip;

[0034] S2: Set the threshold range of signal strength, and the control chip determines whether the current signal strength is within the threshold range;

[0035] S3: If the signal strength is low: increase the gain to amplify the weak signal; if the signal strength is high: reduce the gain to avoid signal saturation and distortion;

[0036] S4: Collect the adjusted signal strength. If the adjusted signal strength is still not within the set range, further adjust the gain value and continuously perform feedback adjustment to ensure that the signal strength is stable within the threshold range.

[0037] S5: If the signal strength is within the set range, lock the current gain value, stop further adjustment, sample the signal strength regularly, and restart the AGC adjustment process if the signal environment changes.

[0038] The control method of the control and monitoring module comprises the following steps:

[0039] S1: The output signal strength of the signal amplifier is collected in real time through the sampling circuit, sampling is performed at fixed intervals, and the signal strength data is transmitted to the main control chip for analysis;

[0040] S2: Monitor the operating temperature of the signal amplifier and control module through the temperature sensor. If the temperature is higher than the set safety range, an alarm signal is triggered and the signal gain is reduced to reduce power consumption and heat generation;

[0041] S3: Detect the voltage and current of the power supply to avoid overcurrent or low voltage. If the power supply voltage is abnormal, immediately reduce the gain of the signal amplifier to reduce power consumption and keep the system stable.

[0042] S4: Compare the real-time collected signal strength and temperature parameters with the set values. If the signal strength is too low, increase the gain of the signal amplifier to maintain the signal quality. If the signal strength is too high or the temperature is too high, reduce the signal gain to prevent the device from overheating or signal distortion.

[0043] S5: When the temperature or power supply voltage exceeds the safety range, an alarm is triggered and gain reduction protection is performed. If the overheating situation persists, the power supply is automatically cut off or the system enters standby mode to ensure system safety.

[0044] S6: Record signal strength, temperature, power supply voltage and other parameters in real time to facilitate fault analysis and system optimization, and transmit data to the host computer or monitoring terminal through wireless or wired communication interface to achieve remote monitoring.

[0045] Assuming that the drone is flying in an open area, the signal from the remote control is received by the input antenna, first filtered out by a filter to remove noise, and then amplified by the signal amplifier. During this process, the automatic gain controller automatically adjusts the gain according to the signal strength to ensure that the signal is not too weak or too strong. The control and monitoring module monitors the signal strength and chip temperature in real time, and immediately adjusts or alarms if an abnormality is found. For example, if the temperature is too high, the system will automatically reduce the signal gain, reduce power consumption and heat generation to protect the equipment. At the same time, all key parameters will be recorded in real time and transmitted to the host computer or monitoring terminal through a wireless or wired communication interface to achieve remote monitoring. In this way, the operator can understand the working status of the drone remote control signal amplifier in real time and intervene when necessary to ensure the safe flight of the drone.

[0046] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. All technical variations made according to the technical solution of the present invention fall within the protection scope of the present invention.
