[0060] Transient suppression diode U7 works together with resistor R15 and capacitor C30 to provide overvoltage protection for the main control chip. When a transient high voltage appears on the power supply or signal line, the transient suppression diode can quickly conduct and conduct the excess voltage to the ground line to protect the main control chip from damage.

[0061] The design of the main control module ensures the stable operation and efficient performance of the system, and enhances the reliability and safety of the entire system through precise clock signals, stable power supply, signal integrity protection, overvoltage protection and effective grounding processing.

[0062] like Figure 3As shown, the serial debugging module 2 includes a connector J1;

[0063] Pin 1 of connector J1 is grounded, pin 2 of connector J1 is electrically connected to pin 23 of main control chip U5, pin 3 of connector J1 is electrically connected to pin 24 of main control chip U5, pin 4 of connector J1 is connected to 3V3 voltage, and pin 5 of connector J1 is electrically connected to pin 4 of main control chip U5.

[0064] It should be noted that:

[0065] Connector J1 is the core component of the serial debugging module and provides a physical interface for connecting debugging equipment. This allows developers to interact with the system through standard debugging tools to perform operations such as program downloading, data monitoring or behavior tracking.

[0066] Pins 2 and 3 of connector J1 are electrically connected to pins 23 and 24 of the main control chip U5, respectively. These connections can be used for serial data communication (such as UART, I2C, etc.). Such a configuration allows data to be directly transmitted between the main control chip and external devices, facilitating real-time data exchange and system monitoring.

[0067] The serial debugging module 2 supports the development and maintenance of the system by providing stable physical and electrical connections, allowing developers to perform effective program debugging and data exchange, ensuring the programmability and debuggability of the system, thereby improving development efficiency and system maintainability.

[0068] like Figure 4 As shown, the RS485 transceiver module 3 includes an RS485 transceiver chip U8, a connector J2, resistors R16, R17, R21, R22, and a capacitor C33;

[0069] Pin 1 of the RS485 transceiver chip U8 is electrically connected to pin 9 of the main control chip U5, pins 2 and 3 of the RS485 transceiver chip U8 are electrically connected to pin 10 of the main control chip U5, pin 4 of the RS485 transceiver chip U8 is electrically connected to pin 8 of the main control chip U5, pin 5 of the RS485 transceiver chip U8 is grounded, pin 6 of the RS485 transceiver chip U8 is electrically connected to one end of resistor R16 and one end of resistor R21, the other end of resistor R21 is electrically connected to one end of resistor R20 and pin 10 of connector J2. Pin 3 is electrically connected, pin 7 of the RS485 transceiver chip U8 is electrically connected to one end of resistor R17 and one end of resistor R22, the other end of resistor R22 is grounded, the other end of resistor R17 is electrically connected to the other end of resistor R20 and pin 1 of connector J2, pin 8 of the RS485 transceiver chip U8 is electrically connected to the other end of resistor R16, one end of capacitor C33 and 3V3 voltage, the other end of capacitor C33 is grounded, pin 2 and pin 4 of connector J2 are grounded, and pin 5 of connector J2 is connected to 12V voltage.

[0070] It should be noted that:

[0071] The RS485 standard supports long-distance and high-speed data communication, and is suitable for network layout in industrial environments. The RS485 transceiver chip U8 in this embodiment can adopt the RS485 transceiver chip model SP3485. Through the connection between the RS485 transceiver chip U8 and the main control chip U5, the module can perform stable data transmission, and the stability of communication can be maintained even in an environment with more electrical noise.

[0072] Pins 2 and 3 of the RS485 transceiver chip U8 are connected to pin 10 of the main control chip. This configuration allows differential signal transmission and enhances the signal's anti-interference ability. Differential signals can effectively reduce the impact of external electromagnetic interference on the signal and improve communication reliability.

[0073] Pin 5 of connector J2 is connected to 12V voltage, which may be used to drive RS485 transceiver chip U8 or provide necessary voltage for other circuits. The configuration of capacitor C33 helps to smooth the supply voltage and prevent voltage surges from affecting the chip.

[0074] The RS485 transceiver module 3 ensures stable data communication in complex and interference-rich environments through its design. The module's technical features such as power and ground processing, differential signal transmission and terminal resistor configuration work together to improve the reliability of communication and the overall performance of the system.

[0075] like Figure 5 As shown, the RC filter module 4 includes a connector J4, resistors R1, R2, R7, R8, and capacitors C19 and C20;

[0076] Pin 1 of connector J4 is connected to 5V_RF voltage, pin 2 of connector J4 is grounded, pin 3 of connector J4 is electrically connected to one end of resistor R7, the other end of resistor R7 is electrically connected to one end of capacitor C19, one end of resistor R1 and pin 14 of main control chip U5, the other end of capacitor C19 and the other end of resistor R1 are grounded, pin 4 of connector J4 is electrically connected to one end of resistor R8, the other end of resistor R8 is electrically connected to one end of capacitor C20, one end of resistor R2 and pin 15 of main control chip U5, the other end of capacitor C20 and the other end of resistor R2 are grounded.

[0077] It should be noted that:

[0078] The RC filter module 4 forms a low-pass filter through the combination of resistors R7, R8 and capacitors C19, C20. This filter can effectively remove high-frequency noise in the signal and only allow low-frequency signals to pass. This is essential for providing a clean and smooth signal.

[0079] Pin 1 of connector J4 is connected to the 5V_RF voltage. Through the RC network, namely R7, C19 and R8, C20, it can help stabilize the power supply voltage, reduce instantaneous fluctuations and spikes in the power supply, and protect the main control chip U5 from these unstable factors.

[0080] The grounding configuration of capacitors C19 and C20 helps absorb possible electromagnetic interference and power supply noise, thereby protecting the signals received by pins 14 and 15 of the main control chip U5 to be purer and more stable.

[0081] The combination of resistors R7, R8 and capacitors C19, C20 not only provides filtering function, but also helps to adjust the impedance of the signal line and optimize the quality and efficiency of signal transmission.

[0082] By filtering out potentially harmful high-frequency noise and voltage fluctuations, the RC filter module helps protect the sensitive pins connected to the main control chip U5, extending the life of the chip and improving the stability and reliability of the entire system.

[0083] The RC filter module 4 effectively provides signal and power de-noising, smoothing and protection functions through its RC network configuration, which is essential to ensure stable operation of electronic equipment in complex electrical environments.

[0084] like Figure 6 As shown, the temperature sensing module 5 includes a temperature sensing chip U9, resistors R18, R19, and a capacitor C3;

[0085] Pin 1 of the temperature sensor chip U9 is electrically connected to one end of the resistor R18 and pin 30 of the main control chip U5, pin 2, pin 7, pin 8 and pin 9 of the temperature sensor chip U9 are grounded, pin 4 of the temperature sensor chip U9 is electrically connected to one end of the resistor R19 and pin 29 of the main control chip U5, the other end of the resistor R18 and the other end of the resistor R19 are connected to a 3V3 voltage, pin 5 of the temperature sensor chip U9 and one end of the capacitor C3 are connected to a 3V3 voltage, and the other end of the capacitor C3 is grounded.

[0086] It should be noted that:

[0087] The temperature sensor chip U9 may be a digital temperature sensor chip of model MTS01B.

[0088] The temperature sensor chip U9 is the core of the module, responsible for measuring temperature and converting temperature data into electrical signals. The temperature sensor chip U9 has high precision and fast response time, and can provide real-time and accurate temperature readings.

[0089] The configuration of resistors R18 and R19 acts as pull-up resistors here. They connect the signal lines (pins 1 and 4) of the temperature sensor chip U9 to the 3V3 voltage, which helps stabilize the signal level and prevents interference from power supply fluctuations or ground noise during transmission.

[0090] Capacitor C3 plays a role in noise reduction on the power line of the temperature sensor chip U9. It smoothes the power supply voltage and filters out high-frequency noise and transient voltage spikes on the power line, ensuring that the sensor chip receives a stable power supply, thereby improving the performance and reliability of the sensor.

[0091] The temperature sensing module 5 provides high-precision temperature measurement, stable signal transmission, effective power supply noise elimination, good system compatibility and necessary electrical protection.

[0092] like Figure 7 As shown, the first voltage stabilizing module 6 includes capacitors C24, C25, C26, C27, C28, C35, a connector J3, a three-terminal voltage regulator U6, and inductors L2 and L3;

[0093] Pin 1 of the three-terminal voltage regulator U6 is electrically connected to one end of capacitor C24, one end of capacitor C25 and one end of inductor L2, the other end of inductor L2 is connected to 12V voltage, the other end of capacitor C24 and the other end of capacitor C25 are grounded, pin 3 of the three-terminal voltage regulator U6 is electrically connected to one end of capacitor C26, one end of capacitor C27 and one end of inductor L3, the other end of inductor L3 is electrically connected to one end of capacitor C28, the other end of capacitor C26, the other end of capacitor C27 and the other end of capacitor C28 are grounded, pin 3 of the three-terminal voltage regulator U6 outputs 5V voltage and 5V_RF voltage, pin 4 of the three-terminal voltage regulator U6 is grounded, pin 1 of connector J3 and one end of capacitor C35 are connected to 12V voltage, and the other end of capacitor C35 is grounded.

[0094] It should be noted that:

[0095] The three-terminal voltage regulator U6 is the core of the module, which is responsible for converting and stabilizing the input voltage into the output 5V voltage. The three-terminal voltage regulator U6 can adopt the three-terminal voltage regulator model LM7805CTD. This type of voltage regulator usually has high efficiency and good load regulation characteristics, and can provide a stable output voltage, even when the input voltage or load conditions change, the output voltage can be kept stable.

[0096] The design of the three-terminal regulator U6 not only stabilizes the voltage, but also converts the higher 12V voltage into 5V and 5V_RF voltages, which is very important for powering electronic devices and circuits that require a 5V power supply.

[0097] The first voltage stabilizing module 6 provides stable voltage output, effective input / output filtering, power supply decoupling, and good electromagnetic compatibility through a three-terminal voltage stabilizer U6.

[0098] like Figure 8 As shown, the second voltage stabilizing module 7 includes a low voltage difference linear voltage stabilizing chip U10, capacitors C29, C31, C32, and C1;

[0100] It should be noted that:

[0101] The low voltage dropout linear voltage regulator chip U10 can convert the higher 5V input voltage into a 3.3V output voltage. In this embodiment, the low voltage dropout linear voltage regulator chip U10 can use a low voltage dropout linear voltage regulator chip with a model number of ME6208A33M3G. The main advantage of the low voltage dropout regulator is that only a small difference is required between the input and output voltages, which enables it to work efficiently when the input voltage is close to the output voltage, and is suitable for low-power devices.

[0102] Due to the low dropout characteristic, LDO regulators generally have higher efficiency and lower power consumption, which is very important for extending battery life and reducing heat generation, especially in portable and battery-powered devices.

[0103] Capacitors C29, C31, C32 and C1 are connected to the output of the low voltage drop linear regulator chip U10 to stabilize the output voltage and filter out noise. These capacitors help smooth the output voltage, reduce voltage fluctuations and ripples, and ensure that the electronic devices connected to the voltage regulator module can obtain stable and reliable power.

[0104] The configuration of capacitors also helps suppress high-frequency noise and transient spikes on the power line, which is critical to improving the overall performance and reliability of the circuit. Especially in sensitive digital circuits and communication equipment, such a stable and clean power supply is essential.

[0105] The second voltage stabilization module 7 provides efficient voltage conversion, stabilization and noise reduction functions through the low voltage difference linear voltage stabilization chip U10, ensuring the high efficiency and reliability of the power supply.

[0106] The working principle of a system standing wave power online monitoring device of this embodiment is as follows:

[0107] Main control module: The main control chip U5 and its related circuits are responsible for controlling and coordinating the work of the entire system and processing data and signals from other modules.

[0108] Serial debug module: Provides a serial debug interface through connector J1 for system debugging and monitoring.

[0109] RS485 transceiver module: RS485 communication is realized through the RS485 transceiver chip U8 and its related circuits, which is used to exchange data with other devices.

[0110] RC filter module: Filters the input RF signal through connector J4 and RC filter circuit, and transmits the filtered signal to the main control chip for processing.

[0111] Temperature sensor module: Temperature measurement is achieved through the temperature sensor chip U9 and its related circuits, and the temperature data is transmitted to the main control chip.

[0112] The first voltage regulator module: converts the 12V input voltage into stable 5V and 5V_RF voltages through the three-terminal regulator U6 and its related circuits to provide power for the system.

[0113] The second voltage regulator module: The 5V voltage is further converted into a 3.3V voltage through the low voltage difference linear voltage regulator chip U10 and its related circuits to provide a stable operating voltage for the main control chip and other low voltage devices.

[0114] Through the coordinated work of the above modules, online monitoring of the system standing wave power is achieved.

[0115] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
