[0002] In the fields of industrial automation, precision measurement and control, and high-speed communication, the generation, transmission, acquisition, and processing of high-frequency pulse signals are among the core technologies. As modern industrial equipment develops towards higher speed, higher precision, and higher reliability, higher requirements are placed on the processing capabilities and stability of pulse signals, involving the integration of multiple disciplines such as electronics, communications, computers, and control.

[0003] However, in the field of pulse signal transmission technology, existing pulse signal transmission circuits still have certain limitations in practical applications. These circuits often lack protective devices, making them vulnerable to external interference such as voltage fluctuations and current surges. This results in insufficient reliability and stability of the pulse signal, consequently affecting the normal operation of subsequent equipment. Furthermore, the structure of existing circuits is relatively complex. Besides the MOS transistor drive circuit necessary for basic functionality, additional acceleration circuits are usually required to meet usage requirements. This not only increases the difficulty of circuit design and fabrication but also raises costs. Moreover, the complex structure reduces the stability of circuit operation to some extent.

The embodiments of this application will be further described below with reference to the accompanying drawings.

[0023] Figure 1 This is a structural block diagram of a pulse signal transmitting circuit provided in an embodiment of this application. Figure 2 This is a circuit diagram of a pulse signal transmitting circuit provided in an embodiment of this application.

[0024] Firstly, such as Figure 1 and Figure 2As shown, a pulse signal transmitting circuit is provided. The circuit includes an optocoupler isolation module 101, a logic control module 102, and a pulse output module 103. The optocoupler isolation module 101 is connected to the pulse output module 103 through the logic control module 102. The optocoupler isolation module 101 includes a logic optocoupler P17, and the pulse output module 103 includes a MOSFET Q28. The optocoupler isolation module 101 is used to acquire a control signal and control the on / off state of the logic optocoupler P17 based on the control signal. The logic control module 102 is used to send an electrical signal that alternates between high and low levels to the pulse output module 103 based on the on / off state of the logic optocoupler P17. The pulse output module 103 is used to control the MOSFET Q28 to periodically switch between on and off states based on the electrical signal, so as to output a pulse signal at the output terminal of the pulse output module 103.

[0025] First, it should be noted that the circuit includes an optocoupler isolation module 101, a logic control module 102, and a pulse output module 103. The optocoupler isolation module 101 is connected to the pulse output module 103 through the logic control module 102. The optocoupler isolation module 101 includes a logic optocoupler P17, and the pulse output module 103 includes a MOSFET Q28. The optocoupler isolation module 101 is used to acquire control signals and control the on / off state of the logic optocoupler P17 based on the control signals. When the control signal is applied to the input terminal of the logic optocoupler P17, the internal light-emitting diode will turn on or off according to the signal state. If the control signal is an effective level, such as a high level, the LED lights up, illuminating the photosensitive element on the output side, making it conduct, thereby realizing the transmission of the control signal from the input side to the output side. If the control signal is an invalid level, such as a low level, the LED is off, the photosensitive element is off, and the input and output sides are electrically isolated. This on / off control based on control signals utilizes light as a medium to transmit electrical signals. At the same time, the internal packaging structure completely isolates the input and output sides electrically, which can effectively transmit control logic and block voltage interference, surge impact and ground loop current on both sides, ensuring the stability and safety of the circuit system.

[0026] In addition, the logic control module 102 is used to send an electrical signal that alternates between high and low levels to the pulse output module 103 based on the on / off state of the logic optocoupler P17. The pulse output module 103 is used to control the MOS transistor Q28 to periodically switch between on and off states based on the electrical signal that alternates between high and low levels, so as to output a pulse signal at the output terminal of the pulse output module 103. The periodic switching between on and off states of the MOS transistor Q28 makes the voltage at the output terminal of the pulse output module 103 show a periodic alternation between high and low levels, thereby forming a continuous pulse waveform with parameters such as frequency and duty cycle.

[0027] The system provided in the first aspect, through the coordinated operation of the optocoupler isolation module and the logic control circuit, can efficiently generate alternating electrical signals to precisely drive the MOSFET, thereby outputting pulse signals. This eliminates the need for complex isolation transformers or relay components in traditional circuits, significantly simplifying the circuit structure, reducing hardware costs and size, and ensuring timely switching actions through the fast response characteristics of the optocoupler. Simultaneously, it maintains high stability in parameters such as the duty cycle and frequency of the output pulse signal, greatly improving the reliability of the pulse signal.

[0028] In one possible implementation, such as Figure 2 As shown, the optocoupler isolation module 101 further includes a first transistor Q25, which is connected to the logic optocoupler P17. The optocoupler isolation module 101 is used to acquire a control signal and control the on / off state of the logic optocoupler P17 based on the control signal, including: the optocoupler isolation module 101 acquires the control signal, and when the control signal is a high-level signal, turns on the first transistor Q25 to control the logic optocoupler P17 to be on; when the control signal is a low-level signal, turns off the first transistor Q25 to control the logic optocoupler P17 to be off.

[0029] It should be noted that the optocoupler isolation module 101 also includes a first transistor Q25, which is connected to the logic optocoupler P17. The optocoupler isolation module 101 is used to acquire control signals and, when the control signal is a high-level signal, turns on the first transistor Q25 to control the logic optocoupler P17 to turn on. Specifically, when the output is high-level, the collector and emitter of the first transistor Q25 are connected, indirectly grounding the third pin of the logic optocoupler P17, achieving the goal that the voltage between the first and third pins of the logic optocoupler P17 is greater than the threshold voltage, thus enabling the fourth and fifth pins of the logic optocoupler P17 to turn on, thereby controlling the logic optocoupler P17 to turn on. In some embodiments, it can be understood that the threshold voltage range can be 1.2~1.8V. The range is affected by the driving current of the LED on the input side of the device (≥10mA), the sensitivity of the photodetector on the output side, and the internal circuit design. The turn-on threshold voltage of different devices has certain differences, and the data range of the threshold voltage is not limited here.

[0030] It should also be noted that when the output is low, the collector and emitter of the first transistor Q25 are not conducting, which fails to meet the condition that the voltage between the first and third pins of the logic optocoupler P17 is greater than the threshold voltage. The fourth and fifth pins of the logic optocoupler P17 are in the off state, thereby controlling the logic optocoupler P17 to disconnect. In some embodiments, it can be understood that the threshold voltage range can be 1.2~1.8V. The range is affected by the driving current of the LED on the input side of the device (≥10mA), the sensitivity of the photodetector on the output side, and the internal circuit design. The conduction threshold voltage of different devices has certain differences. The data range of the threshold voltage is not limited here.

[0031] By controlling the high and low levels of the control signal in conjunction with a transistor to control the conduction and cutoff of the logic optocoupler P17, the problem of weak driving capability of high and low level signals can be overcome. Specifically, the LED at the input terminal of the logic optocoupler P17 requires a certain driving current to operate stably, but its driving capability of high and low level signals is weak. The transistor here acts as a current amplification element, converting the weak control signal into a current sufficient to drive the optocoupler. Secondly, it can enhance the electrical isolation effect. The optocoupler itself has achieved electrical isolation between the input and output sides, and the transistor further acts as a buffer, blocking interference from ground loop currents on both sides. Especially in high and low voltage mixed circuits, it can prevent voltage spikes or surges on the output side from entering the control side, improving circuit stability.

[0032] In one possible implementation, such as Figure 2 As shown, the logic control module 102 includes a second transistor Q29; the logic control module 102 is used to send an electrical signal that alternates between high and low levels to the pulse output module based on the on / off state of the logic optocoupler P17, including: when the logic optocoupler P17 is on, the logic control module 102 controls the collector voltage of the second transistor Q29 to be in a high potential state to send a high-level electrical signal to the pulse output module; when the logic optocoupler P17 is off, the logic control module 102 controls the collector voltage of the second transistor Q29 to be in a low potential state to send a low-level electrical signal to the pulse output module.

[0033] In some embodiments, the logic control module 102 includes a second transistor Q29. When the logic optocoupler P17 is turned on, the base of the second transistor Q29 is approximately grounded, the voltage between the base and emitter is less than the threshold voltage, and the collector and emitter are not connected, thereby controlling the collector voltage of the second transistor Q29 to be in a high-potential state to send a high-level electrical signal to the pulse output module. When the logic optocoupler P17 is turned off, the base of the second transistor Q29 is connected to a pull-up resistor R166 and is in a high-potential state, the voltage between the base and emitter is greater than the threshold voltage, and the collector and emitter are connected, thereby controlling the collector voltage of the second transistor Q29 to be in a low-potential state to send a low-level electrical signal to the pulse output module. In some embodiments, it is understood that the threshold voltage range for PNP transistors is 0.6~0.7V, and for NPN transistors it is 0.2~0.3V. Due to the influence of manufacturing materials and processes, the data range of the threshold voltage is not limited here. The combination of optocouplers and transistors offers fast response speeds, simple circuit structures, and low costs, ensuring both accurate signal transmission and enhanced system anti-interference capabilities and security.

[0034] In one possible implementation, such as Figure 2 As shown, the logic control module 102 further includes a first resistor R164, an NPN transistor Q26, and a PNP transistor Q27. The second transistor Q29 is connected to the bases of the NPN transistor Q26 and the PNP transistor Q27 through the first resistor R164. The emitter of the NPN transistor Q26 is connected to the emitter of the PNP transistor Q27. The logic control module 102 is used to control the collector voltage of the second transistor to be at a high potential when the logic optocoupler P17 is turned on, so as to send a high-level electrical signal to the pulse output module. When 7 is disconnected, controlling the collector voltage of the second transistor to be in a low potential state to send a low-level electrical signal to the pulse output module includes: the logic control module 102 is used to control the collector voltage of the second transistor to be in a high potential state when the logic optocoupler P17 is turned on, thereby controlling the NPN transistor Q26 to be turned on to send a high-level electrical signal to the pulse output module; and when the logic optocoupler P17 is disconnected, controlling the collector voltage of the second transistor to be in a low potential state, thereby controlling the PNP transistor Q27 to be turned on to send a low-level electrical signal to the pulse output module.

[0035] In some embodiments, it should be noted that the logic control module 102 further includes a first resistor R164, an NPN transistor Q26, and a PNP transistor Q27. The second transistor is connected to the base of the NPN transistor Q26 and the PNP transistor Q27 through the first resistor R164. The emitter of the NPN transistor Q26 is connected to the emitter of the PNP transistor Q27. When the logic optocoupler P17 is turned on, the logic control module 102 controls the collector voltage of the second transistor to be in a high potential state, that is, the voltage at point G is in a high potential state, thereby controlling the NPN transistor Q26 to turn on, so as to send a high-level electrical signal to the pulse output module. At this time, the voltage at point H is in a high potential state. When the logic optocoupler P17 is turned off, the logic control module 102 controls the collector voltage of the second transistor to be in a low potential state, that is, the voltage at point G is in a low potential state, thereby controlling the PNP transistor Q27 to turn on, so as to send a low-level electrical signal to the pulse output module. At this time, the voltage at point H is in a low potential state. The NPN transistor Q26 and the PNP transistor Q27 form a complementary symmetry circuit. The complementary symmetry circuit can significantly improve the signal output power and efficiency. Compared with the single-transistor amplifier circuit, the complementary symmetry structure can achieve bidirectional signal amplification without static bias current, reducing static power consumption. Secondly, it can effectively improve waveform distortion. Since the two transistor types process the positive and negative half-cycle signals respectively, the waveform of the input signal can be reproduced more completely, reducing nonlinear distortion and improving signal stability.

[0036] In one possible implementation, the pulse output module is used to control the MOS transistor to periodically switch between on and off states based on the electrical signal, so as to output a pulse signal at the output terminal of the pulse output module. This includes: the pulse output module controlling the MOS transistor to be on when the electrical signal is a high-level electrical signal, and controlling the MOS transistor to be off when the electrical signal is a low-level electrical signal, so as to periodically switch the MOS transistor between on and off states, so as to output a pulse signal at the output terminal of the pulse output module.

[0037] It should be noted that the pulse output module controls the MOSFET to turn on when the electrical signal is high and to turn off when the electrical signal is low, thus periodically switching the MOSFET between on and off states to output a pulse signal at the output terminal of the pulse output module. The MOSFET can be an N-type MOSFET, which includes a drain, source, and gate. The voltage between the gate and source controls its on / off state. When the MOSFET is in the off state, the voltage between the gate and source is less than the threshold voltage, no conductive channel is formed below the gate, and the drain and source are essentially open-circuited, with no current flowing through. When the MOSFET is in the on state, the voltage between the gate and source is greater than the threshold voltage, and the gate electric field forms an N-type channel in the P-type substrate, connecting the source and drain. If the voltage between the drain and source is greater than 0, current flows through the drain and source, and the MOSFET acts as a low-resistance path, achieving switch closure. Utilizing the extremely high gate input impedance of the MOSFET, only a very small control current is needed to achieve state switching, significantly reducing the power consumption and design complexity of the drive circuit. Furthermore, rapid switching significantly reduces energy loss during the transition process, avoids additional heat generation caused by devices operating in the non-saturation region for extended periods, and improves overall circuit efficiency. Clear high / low level control logic ensures stable and controllable switching states of the MOSFET, and combined with rapid switching characteristics, it can accurately generate high-frequency pulse signals.

[0038] In one possible implementation, such as Figure 2 As shown, the optocoupler isolation module 101 also includes a first capacitor and a second resistor. The first capacitor and the second resistor are connected in parallel and then connected in series with the first transistor.

[0039] It should be noted that the optocoupler isolation module 101 also includes a first capacitor C122 and a second resistor R162. The first capacitor C122 and the second resistor R162 are connected in parallel and then connected in series with the first transistor Q25. The first capacitor C122 and the second resistor R162 form an RC parallel circuit. When the signal frequency is low, the capacitive reactance of the first capacitor C122 is extremely large, and the total impedance of the circuit is approximately equal to that of the second resistor R162, which can stably pass DC or low-frequency signals and avoid excessive attenuation of low-frequency signals during transmission. When the frequency increases to a certain level, the capacitive reactance of the first capacitor C122 decreases significantly, and the total impedance approaches 0, which can efficiently pass high-frequency signals and meet the low-loss transmission requirements of high-speed signals. Secondly, the RC parallel structure can play a dual role of buffering and filtering. The second resistor R162 can suppress the instantaneous large current of the capacitor at high frequencies and avoid damage to circuit components caused by spikes during sudden changes in high-frequency signals. The first capacitor C122 can absorb high-frequency noise and smooth high-frequency glitches in the signal. The combination of the two ensures the stability of signal transmission and improves the anti-interference capability of the circuit.

[0040] In one possible implementation, such as Figure 2 As shown, the pulse output module 103 also includes a third resistor R160 and a resettable fuse. The third resistor R160 and the resettable fuse are connected in parallel and then connected in series with the MOS transistor.

[0041] It should be noted that the pulse output module 103 also includes a third resistor R160 and a resettable fuse. The third resistor R160 and the resettable fuse are connected in parallel and then in series with the MOSFET. This effectively suppresses false triggering. In some embodiments, the output of these solutions lacks protection devices or uses simple filter capacitors, which is insufficient. The resettable fuse utilizes the temperature-resistance characteristic change to achieve overcurrent protection. The parallel resistor accelerates triggering and effectively reduces the risk of false triggering. In the event of a fault, the third resistor R160 provides the minimum discharge path for the resettable fuse, ensuring that sufficient voltage / current is maintained across the resettable fuse during the fault period, stabilizing it in a high-resistance state until the fault is cleared. This improves the accuracy of pulse generation and effectively protects against or avoids overcurrent interference between the pulse transmitting and receiving devices.

[0042] Figure 3 This is an optional flowchart of the pulse signal transmission method provided in the embodiments of this application. Figure 3 The method may include, but is not limited to, steps S100 to S300.

[0043] Secondly, such as Figure 3 As shown, a pulse signal transmission method is proposed, the method comprising: S100: Use the optocoupler isolation module to obtain the control signal, and control the on / off state of the logic optocoupler based on the control signal.

[0044] S200: The logic control module sends an electrical signal that alternates between high and low levels to the pulse output module based on the on / off state of the logic optocoupler.

[0045] S300: The pulse output module uses an electrical signal to control the MOS transistor to periodically switch between on and off states, so as to output a pulse signal at the output terminal of the pulse output module.

[0046] First, it should be noted that the circuit includes an optocoupler isolation module, a logic control module, and a pulse output module. The optocoupler isolation module is connected to the pulse output module through the logic control module. The optocoupler isolation module includes a logic optocoupler, and the pulse output module includes a MOSFET. The optocoupler isolation module is used to acquire control signals and control the on / off state of the logic optocoupler based on these signals. When a control signal is applied to the input of the logic optocoupler, the internal LED will turn on or off according to the signal state. If the control signal is valid (e.g., high), the LED illuminates, illuminating the photosensitive element on the output side and turning it on, thus transmitting the control signal from the input to the output side. If the control signal is invalid (e.g., low), the LED is off, the photosensitive element is off, and the input and output sides are electrically isolated. This on / off control based on control signals utilizes light as a medium to transmit electrical signals, while the internal packaging structure completely isolates the input and output sides electrically. This effectively transmits control logic while blocking voltage interference, surge impacts, and ground loop currents, ensuring the stability and safety of the circuit system.

[0047] In addition, the logic control module is used to send an electrical signal that alternates between high and low levels to the pulse output module based on the on / off state of the logic optocoupler. The pulse output module is used to control the MOSFET to periodically switch between on and off states based on the electrical signal that alternates between high and low levels, so as to output a pulse signal at the output terminal of the pulse output module. The periodic switching between on and off states of the MOSFET makes the voltage at the output terminal of the pulse output module show a periodic alternation between high and low levels, thereby forming a continuous pulse waveform, and the parameters such as the frequency and duty cycle of the pulse waveform are also included.

[0048] The method provided in the second aspect, through the coordinated operation of the optocoupler isolation module and the logic control circuit, can efficiently generate alternating electrical signals to precisely drive the MOSFET, thereby outputting pulse signals. This eliminates the need for complex isolation transformers or relay components in traditional circuits, significantly simplifying the circuit structure, reducing hardware costs and size, and ensuring timely switching actions through the fast response characteristics of the optocoupler. Simultaneously, it maintains high stability in parameters such as the duty cycle and frequency of the output pulse signal, greatly improving the reliability of the pulse signal.

[0049] This application also provides an electronic device, such as... Figure 4 As shown, the electronic device 1400 includes: One or more processors 1410; The memory 1420 stores one or more programs, which, when executed by one or more processors 1410, cause the one or more processors 1410 to implement the pulse signal transmission method provided in any embodiment of this application.

[0050] Memory 1420, as a non-transitory network system, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, memory 1420 may include high-speed random access memory and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. In some embodiments, memory 1420 may optionally include remotely located memories 1420 relative to processor 1410, which can be connected to processor 1410 via a network. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

[0051] The memory 1420 can be implemented as a read-only memory (ROM), a static storage device, a dynamic storage device, or a random access memory (RAM).
