Description

Technical Field

[0001] This utility model relates to the field of receiver technology, and more specifically, to a receiver intelligent control module. Background Technology

[0002] In the field of receiver technology, receivers need to acquire external signals through receiving antennas, and the quality of signal reception directly affects the subsequent data processing and application effects. With the increasing requirements for signal stability in fields such as communication and navigation, receivers often need to operate in environments where the signal source location changes (such as in mobile vehicle scenarios) or where there is strong external electromagnetic interference.

[0003] Utility model patent CN210270146U discloses a radio-guided underwater detection device, specifically relating to the field of radio monitoring technology. The device includes a detection host with a signal receiving mechanism connected to its side via a connecting line. The signal receiving mechanism includes an antenna assembly and a support assembly. The antenna assembly includes a base with an antenna fixed to its top. A circular plate is integrally formed at the bottom of the base, and a suction cup is fixed to the bottom of the circular plate. The support assembly includes a circular shell mounted at the bottom of the base. The circular plate and suction cup are both located inside the circular shell. A threaded rod is fixed to the bottom of the circular shell, and a hollow rod extends into the interior of the hollow rod at its bottom end.

[0004] Although this invention enables the antenna assembly to be stably placed and facilitates height adjustment, thus improving signal reception and monitoring performance, the fixed design of the antenna means that it cannot automatically trigger angle adjustment when the external signal strength weakens, which can easily lead to signal reception interruption or quality degradation. Utility Model Content

[0005] The purpose of this invention is to provide a receiver intelligent control module to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A receiver intelligent control module includes a receiving antenna, a signal processing module, and a position control module. Both the signal processing module and the position control module are electrically connected to the receiving antenna. The position control module includes a signal strength detector, an analog-to-digital converter (ADC), a microprocessor, a lateral control unit, a longitudinal control unit, and an activation circuit. The output terminal of the receiving antenna is connected to the input terminal of the signal strength detector. The output terminal of the signal strength detector is simultaneously connected to the input terminals of the ADC and the activation circuit. The output terminals of the ADC and the activation circuit are respectively connected to different input terminals of the microprocessor. The different output terminals of the microprocessor are respectively connected to the input terminals of the lateral control unit and the longitudinal control unit. The signal strength detector acquires the signal strength of the receiving antenna. The activation circuit compares the signal strength with a reference voltage value using a voltage comparator. After receiving the output signal from the activation circuit, the microprocessor controls the lateral control unit and the longitudinal control unit to change the deflection angle of the receiving antenna.

[0007] Preferably, the microprocessor includes a comparison unit, a storage unit, and a control unit. The comparison unit and the control unit are both signal-connected to the storage unit. The output terminal of the analog-to-digital converter chip is electrically connected to the input terminal of the storage unit. The comparison unit is used to compare the data output by the analog-to-digital converter chip at adjacent times, thereby determining the control effect brought by the horizontal control unit and the vertical control unit. Preferably, the turn-on circuit includes an operational amplifier U, a power supply VCC, a resistor R1, and a resistor R2. The non-inverting input of the operational amplifier U is connected to the output of the signal strength detector. The first end of the resistor R1 is connected to the power supply VCC. The second end of the resistor R1 is connected to the first end of the resistor R2. The second end of the resistor R2 is grounded. The inverting input of the operational amplifier U is connected to the second end of the resistor R1. The output of the operational amplifier U is electrically connected to the input of the control unit. Preferably, the lateral control unit controls the lateral deflection angle of the receiving antenna by controlling motor M1 through an H-bridge circuit, and the longitudinal control unit controls the longitudinal deflection angle of the receiving antenna by controlling motor M2 through an H-bridge circuit. In these three settings, the microprocessor's comparison unit and storage unit work together to compare signal data from adjacent moments in real time, determine whether the antenna adjustment direction is effective, avoid blind adjustments, and significantly shorten the time it takes for the antenna to find the optimal receiving angle. The voltage divider structure composed of resistors R1 and R2 in the power-on circuit allows for flexible setting of the reference voltage by adjusting the resistance value, which can adapt to the signal strength requirements of different scenarios and solve the problem of poor adaptability of fixed reference voltage. Both the horizontal control unit and the vertical control unit use H-bridge circuits to drive the motor, which not only enables bidirectional deflection of the antenna in two directions and accurate tracking of signal sources changing in multiple directions, but also allows the adjustment in the two directions to be performed independently, reducing unnecessary actions and lowering overall energy consumption.

[0008] Preferably, the signal processing module includes a radio frequency filter, a low-noise amplifier, a local oscillator, a mixer, an intermediate frequency filter, an intermediate frequency amplifier, a demodulator, and a baseband amplifier. The receiving antenna, the radio frequency filter, the low-noise amplifier, the mixer, the intermediate frequency filter, the intermediate frequency amplifier, the demodulator, and the baseband amplifier are electrically connected in sequence, and the output terminal of the local oscillator is also connected to the input terminal of the mixer. This setup establishes an efficient signal processing link, providing high-quality signal support for subsequent data applications and outputting standard baseband signals that meet requirements.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model obtains the antenna signal strength in real time by setting a signal strength detector. The circuit opens to accurately determine whether the signal is lower than the reference value through a voltage comparator. Once the threshold is triggered, the microprocessor can immediately control the horizontal control unit and the vertical control unit to adjust the antenna angle. The horizontal control unit and the vertical control unit use an H-bridge circuit to drive the motor, which can realize bidirectional and stable deflection of the antenna, adapt to the multi-directional changes of the signal source, and ensure continuous tracking of the optimal signal in moving or signal fluctuating scenarios. 2. This utility model forms a feedback mechanism by setting up a comparison unit and a storage unit, which can store signal data of adjacent time moments output by the analog-to-digital converter chip, and judge the signal change trend after antenna adjustment by comparison; if the signal is enhanced after adjustment, the control unit can continue to optimize in that direction; if the signal is weakened, it can be adjusted in the opposite direction in time to avoid invalid operation; it solves the problem of lack of adjustment feedback in the prior art, greatly shortens the time for the antenna to find the optimal angle, and improves control efficiency.

Detailed Implementation

[0011] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0012] Please see Figures 1-7 The present invention provides the following technical solution: A receiver intelligent control module includes a receiving antenna 100, a signal processing module 200, and a position control module 300. Both the signal processing module 200 and the position control module 300 are electrically connected to the receiving antenna 100. The position control module 300 includes a signal strength detector 301, an analog-to-digital converter chip 302, a microprocessor 303, a lateral control unit 304, a longitudinal control unit 305, and an activation circuit 306. The output of the receiving antenna 100 is connected to the input of the signal strength detector 301. The output of the signal strength detector 301 is simultaneously connected to the inputs of both the analog-to-digital converter chip 302 and the activation circuit 306. The outputs of the analog-to-digital converter chip 302 and the activation circuit 306 are respectively connected to different inputs of the microprocessor 303. Different outputs of the microprocessor 303 are respectively connected to the inputs of the lateral control unit 304 and the longitudinal control unit 305. The detector 301 acquires the signal strength of the receiving antenna 100. The activation circuit 306 compares the signal strength with the reference voltage value through a voltage comparator. After receiving the output signal from the activation circuit 306, the microprocessor 303 controls the horizontal control unit 304 and the vertical control unit 305 to change the deflection angle of the receiving antenna 100. The signal strength detector 301 monitors the signal in real time. Combined with the voltage comparison function of the activation circuit 306, it can accurately identify whether the signal received by the receiving antenna 100 is lower than the reference value, avoiding adjustment delays caused by inaccurate signal strength judgment. The microprocessor 303 can directly control the horizontal control unit 304 and the vertical control unit 305 to adjust the antenna angle without manual intervention. It is suitable for mobile carriers or scenarios with strong electromagnetic interference, ensuring that the receiving antenna 100 can always track the signal source, and solving the problem of signal interruption or quality degradation caused by the inability of existing fixed antennas to adjust automatically.

[0013] In this embodiment, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The microprocessor 303 includes a comparison unit 3030, a storage unit 3031, and a control unit 3032. Both the comparison unit 3030 and the control unit 3032 are signal-connected to the storage unit 3031. The output terminal of the analog-to-digital converter chip 302 is electrically connected to the input terminal of the storage unit 3031. The comparison unit 3030 is used to compare the data output of the analog-to-digital converter chip 302 at adjacent times, thereby determining the control effect brought by the horizontal control unit 304 and the vertical control unit 305. The storage unit 3031 can retain the signal data at adjacent times, providing a basis for comparison for the comparison unit 3030 and avoiding the problem of not being able to judge the adjustment effect due to data loss. The comparison unit 3030 determines whether the adjustment of the horizontal control unit 304 and the vertical control unit 305 is effective through data comparison. The control unit 3032 can adjust the control strategy in a timely manner according to the result. If the signal is enhanced after adjustment, it continues to optimize; if it is weakened, it adjusts in the opposite direction, forming a closed-loop feedback mechanism, which greatly shortens the time for the receiving antenna 100 to find the optimal angle and improves control efficiency.

[0014] Specifically, the power-on circuit 306 includes an operational amplifier U, a power supply VCC, resistors R1 and R2. The non-inverting input of the operational amplifier U is connected to the output of the signal strength detector 301. The first end of resistor R1 is connected to the power supply VCC, the second end of resistor R1 is connected to the first end of resistor R2, and the second end of resistor R2 is grounded. The inverting input of the operational amplifier U is connected to the second end of resistor R1. The output of the operational amplifier U is electrically connected to the input of the control unit 3032. The voltage divider circuit composed of resistors R1 and R2 can accurately set the reference voltage by adjusting the resistance value, adapting to the signal strength requirements in different scenarios and avoiding the problem of narrow applicability caused by a fixed reference voltage.

[0015] Furthermore, the lateral control unit 304 controls the motor M1 via an H-bridge circuit to control the lateral deflection angle of the receiving antenna 100, and the longitudinal control unit 305 controls the motor M2 via an H-bridge circuit to control the longitudinal deflection angle of the receiving antenna 100. The H-bridge circuit has the function of driving the motor to rotate in both directions, allowing the lateral control unit 304 to control the motor M1 to rotate in both directions and the longitudinal control unit 305 to control the motor M2 to rotate in both directions, so as to realize the flexible deflection of the receiving antenna 100 in both lateral and longitudinal directions, adapting to scenarios where the signal source changes in multiple directions. The lateral and longitudinal adjustments are independent of each other, and can be adjusted separately for signal changes in the two directions without overall linkage, reducing unnecessary adjustment actions and reducing energy consumption.

[0016] In this embodiment, please refer to Figure 1 and Figure 2The signal processing module 200 includes an RF filter 201, a low-noise amplifier 202, a local oscillator 203, a mixer 204, an intermediate frequency filter 205, an intermediate frequency amplifier 206, a demodulator 207, and a baseband amplifier 208. The receiving antenna 100, RF filter 201, low-noise amplifier 202, mixer 204, intermediate frequency filter 205, intermediate frequency amplifier 206, demodulator 207, and baseband amplifier 208 are electrically connected in sequence. The output of the local oscillator 203 is also connected to the input of the mixer 204. The signal processing module 200 works in conjunction with the receiving antenna 100 to provide a foundation for subsequent signal processing. In conjunction with the position control module 300, it further enhances the overall signal reception and processing effect. The RF filter 201 and the IF filter 205 filter RF and IF interference respectively. The low-noise amplifier 202 reduces noise when amplifying the signal, effectively improving signal purity and avoiding interference signals from affecting subsequent processing. It provides high-quality signals for the demodulator 207 and the baseband amplifier 208. The local oscillator 203 and the mixer 204 work together to convert the signal into an IF signal, which is convenient for the IF amplifier 206 to amplify the signal. This solves the problems of high-frequency signal amplification difficulty and easy noise superposition, and improves signal amplification efficiency and quality.

[0017] When the receiver intelligent control module of this utility model is in use, the receiving antenna 100 serves as the signal input terminal. It first captures the target signal in the external space to complete the initial signal reception. The receiving antenna 100 divides the captured signal into two paths for transmission: the first path is transmitted to the signal processing module 200 for subsequent signal filtering, amplification, demodulation and other processing; the second path is transmitted to the signal strength detector 301 in the position control module 300 for signal strength monitoring and triggering the angle adjustment of the receiving antenna 100. The second signal transmitted by the receiving antenna 100 enters the signal strength detector 301. The signal strength detector 301 detects the strength of the signal in real time and converts the strength information into a corresponding analog voltage signal. The analog voltage signal output by the signal strength detector 301 is divided into two paths: the first path is transmitted to the analog-to-digital converter chip 302 for subsequent digital analysis; the second path is transmitted to the activation circuit 306 for trigger judgment. In the power-on circuit 306, the connection point of resistors R1 and R2 provides a reference voltage to the inverting input of operational amplifier U. The analog voltage signal output by signal strength detector 301 is connected to the non-inverting input of operational amplifier U. Operational amplifier U compares the signal strength voltage at the non-inverting input with the reference voltage at the inverting input: if the signal strength voltage is less than the reference voltage, it indicates that the signal is too weak, and operational amplifier U outputs a low level to the control unit 3032 of microprocessor 303; if the signal strength voltage is not less than the reference voltage, it indicates that the signal is normal, and outputs a high level, and receiving antenna 100 maintains the current angle. The analog-to-digital converter chip 302 converts the analog voltage signal output by the signal strength detector 301 into a digital signal and transmits the digital signal to the storage unit 3031 of the microprocessor 303. The storage unit 3031 stores the digitized signal strength data (S1 and S2) at adjacent time points (e.g., time t1 and time t2) in real time. The comparison unit 3030 of the microprocessor 303 is connected to the storage unit 3031 and retrieves the signal strength data (S1 and S2) at adjacent time points from the storage unit 3031 and compares their magnitudes. If S2 is greater than S1, it means that the previous antenna adjustment direction was correct, and subsequent fine-tuning can continue along that direction. If S2 is less than S1, it means that the previous antenna adjustment direction was incorrect, and subsequent adjustment needs to be reversed. If S2 is equal to S1, it means that the current angle is close to the optimal angle, and small-scale trial adjustments can be made. The comparison unit 3030 transmits the comparison result to the control unit 3032. The control unit 3032, in conjunction with the output signal of the activation circuit 306, generates angle adjustment commands (including adjustment direction and adjustment range) for the lateral control unit 304 and the longitudinal control unit 305. The lateral control unit 304 controls the forward or reverse rotation of the motor M1 through the H-bridge circuit (e.g., forward rotation corresponds to the antenna deflecting to the left, and reverse rotation corresponds to the antenna deflecting to the right). The motor M1 drives the receiving antenna 100 to complete the lateral angle adjustment; the longitudinal control unit 305 similarly completes the longitudinal angle adjustment. The signal transmitted by the receiving antenna 100 enters the RF filter 201, which filters out high-frequency interference components from the signal, outputting a clean RF signal. The filtered RF signal then enters the low-noise amplifier 202, which amplifies the weak RF signal while minimizing the introduction of additional noise, ensuring stable signal reception by subsequent modules. The amplified RF signal enters the mixer 204, while the local oscillator 203 outputs a fixed-frequency local oscillation signal to the mixer 204. The mixer 204 performs a mixing operation on the RF signal and the local oscillation signal, converting the RF signal into a lower-frequency, more easily processed intermediate frequency (IF) signal. The intermediate frequency (IF) signal then enters the IF filter 205, which further filters out interference signals in the IF band, improving the purity of the IF signal. The filtered IF signal then enters the IF amplifier 206, which amplifies the IF signal a second time to compensate for signal attenuation during mixing and filtering. The amplified IF signal then enters the demodulator 207, which restores the modulation information in the IF signal to obtain the basic baseband signal. The demodulated baseband signal then enters the baseband amplifier 208, which amplifies the baseband signal for the final time and outputs a standard baseband signal that meets the requirements of subsequent data processing, completing the entire signal processing flow.
