Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] The term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. In the description of the present invention, it should be understood that the terms "upper," "inner," "lower," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the present invention described herein can be implemented in orders other than those illustrated or described herein.

[0018] To address the problems existing in the prior art, a signal processing circuit for transmission is disclosed, specifically, as follows: Figure 1 and Figure 2 As shown, the system includes a microcontroller chip 1 and a power supply circuit, an over-vertex analysis circuit 2, and a launch protection circuit, all electrically connected to the microcontroller chip 1. The power supply circuit is connected to pin 1 of the microcontroller chip 1 to provide power. The over-vertex protection circuit is connected to pin 6 of the microcontroller chip 1 to provide the microcontroller chip 1 with the current pulse frequency signal of the target launcher in the current launch state. The launch protection circuit is activated under the control of the microcontroller chip 1 when the current pulse frequency signal of the target launcher meets the target pulse frequency signal. It is understood that this embodiment uses a dual control circuit to connect the target launcher to power and deactivate the circuit protection when the target launcher meets the power-on and detonation conditions, thereby reducing the safety hazards of the target launcher. Furthermore, by integrating the power supply circuit, the over-vertex analysis circuit 2, and the launch protection circuit into the microcontroller chip 1, the circuit can be integrated and miniaturized, facilitating installation and use. Understandably, the over-vertex protection circuit is connected to pin 6 of the microcontroller chip 1, which can provide the microcontroller chip 1 with the current pulse frequency signal of the target launcher in the current launching state, realizing real-time status monitoring, thereby improving the power connection control accuracy of the power connection circuit 3.

[0019] In some embodiments, the power supply circuit includes a generator and a first-stage voltage regulator circuit 5. The generator provides AC voltage to the first-stage voltage regulator circuit 5. The first-stage voltage regulator circuit 5 includes a rectifier diode, a filter capacitor C1, a filter capacitor C2, and a voltage regulator. The rectifier diode rectifies the AC voltage output by the generator into a DC voltage. The filter capacitors C1 and C2 are connected in parallel to filter the DC voltage to obtain a smooth DC voltage. The first-stage voltage regulator includes a first-stage input pin, a first-stage output pin, and a first-stage ground pin. The smooth DC voltage is input to the first-stage voltage regulator from the first-stage input pin and output through the first-stage output pin or grounded through the first-stage ground pin.

[0020] For example, rectifier diodes convert alternating current (AC) to direct current (DC). A bridge rectifier, consisting of four diodes connected in a bridge configuration, can be used. It's understandable that the rectified DC voltage will have ripple. To smooth the output voltage, filter capacitor C1 is rated at 0.1μF / 50V, and filter capacitor C2 is rated at 10μF / 35V. These capacitors serve as filter capacitors for high-frequency and low-frequency filtering, respectively, reducing voltage fluctuations. Similarly, a filter capacitor is also placed at the output terminal to further smooth the regulated DC voltage, reducing output voltage fluctuations and noise. For example, the generator is a wind turbine, and the first-stage voltage regulator circuit 5 can be an LM317 voltage regulator as shown in the diagram.

[0021] In some embodiments, the transmitting signal processing circuit further includes a secondary voltage regulator circuit 6, which is electrically connected to the primary output pin of the primary voltage regulator. The secondary voltage regulator circuit 6 includes a secondary voltage regulator, which includes a secondary input pin, a secondary output pin, and a secondary ground pin. The smoothed DC voltage is input to the secondary voltage regulator through the primary output pin and the secondary input pin, and after being regulated to the target DC voltage by the secondary voltage regulator, it is output through the secondary output pin or grounded through the secondary ground pin.

[0022] For example, a secondary voltage regulator could be the HT7130-1 regulator shown in the diagram. The HT7130-1 is a linear regulator whose primary function is to convert a higher input voltage (Vcc) into a lower and more stable output voltage (Vdd). Specifically, voltage reduction can be achieved through the following steps:

[0023] The secondary input pin is connected to the power supply voltage (Vcc), which is typically a DC voltage higher than the regulator's output voltage.

[0024] The secondary output pin provides a stable DC voltage (Vdd), which is typically lower than the input voltage. The secondary ground pin is connected to the circuit ground to ensure proper functioning of the regulator.

[0025] Furthermore, the secondary voltage regulator circuit 6 also includes filter capacitors C3, C4, and C5. Filter capacitor C3 is connected between the secondary input pin and the secondary ground pin for filtering and decoupling, smoothing the input power supply voltage and reducing the impact of power supply noise and transient changes on the regulator. Filter capacitors C4 and C5 are connected in parallel between the secondary output pin and the secondary ground pin to smooth the output voltage, store energy to cope with load changes, ensure output voltage stability while achieving high-frequency filtering, and further reduce output voltage noise.

[0026] Understandably, by setting up the generator, the first-stage voltage regulator circuit 5, and the second-stage voltage regulator circuit 6, the AC voltage can be converted into a stable DC voltage, effectively improving the stability of the power supply. Furthermore, by setting up filter capacitors C1, C2, C3, C4, and C5, the voltage can be effectively filtered to obtain a smooth DC voltage, thus improving the quality of the power supply.

[0027] In some embodiments, the over-vertex analysis circuit 2 includes a load S1, a conducting resistor R4, and a transistor Q1. Transistor Q1 is electrically connected to pin 6 of the microcontroller chip 1. When S1 is closed, the power supply Vdd powers the vertex analysis circuit through resistor R14 and capacitor C11. Current flows through R4 to the base (B) of the transistor, turning on transistor Q1. When transistor Q1 is on, a low-impedance path is formed between the collector (C) and emitter (E), allowing current to flow through the load. Thus, the VSIN signal enters the base of transistor Q1 through resistor R4, affecting the conduction state of Q1 and controlling the signal flow. Furthermore, when load S1 is on, transistor Q1 conducts under the influence of AC voltage to provide the microcontroller chip 1 with the current pulse frequency signal of the target emitter in the current ejection state.

[0028] In some embodiments, the transmit protection circuit includes a power-on circuit 3 and a power-off circuit 4. The power-on circuit 3 is connected to pins 3 and 4 of the microcontroller chip 1, and the power-off circuit 4 is connected to pin 5 of the microcontroller chip 1. The power-on circuit 3 includes a crystal diode Q2 and a crystal diode Q3. The crystal diode Q2 is used to perform a potential conversion on the target DC voltage input to the secondary output pin, so that the crystal diode Q2 outputs a high-potential target DC voltage to the crystal diode Q3. The crystal diode Q3 is used to conduct after receiving the high-potential target DC voltage. The power-on circuit 3 completes the power-on action. The power-off circuit 4 includes a thyristor K2. One end of the thyristor K2 is grounded, and the other end is connected to the voltage output from the primary output pin. The other end of the thyristor K2 is connected to pin 5 of the microcontroller chip 1 through a resistor R10. The thyristor K2 conducts when the input voltage meets the threshold voltage. It can be understood that the control logic of the microcontroller chip 1 determines when to output a high level to trigger the thyristor K2. The microcontroller's output pin can be programmed to output a high level under specific conditions (such as sensor input, time delay, etc.), thereby triggering the SCR K2. It is understandable that by setting the protection circuit 4, the SCR K2 is ensured to conduct only when the threshold value is met, preventing the target transmitter from being prematurely deactivated and improving launch safety.
