[0051] First, the application scenarios that can be provided by the present application are introduced, such as providing a bypass cabinet intelligent control device, chip and electronic equipment, and realizing automatic and intelligent control of the bypass cabinet by providing a new type of intelligent control device for the bypass cabinet.

[0052] See also Figure 1 , Figure 1: is a schematic diagram of the structure of the bypass cabinet intelligent control device provided in an embodiment of the present application. The bypass cabinet intelligent control device may specifically include a power management module 10, a main control module 20, a voltage monitoring module 30, a current monitoring module 40 and an electric operating mechanism module 50, which may be specifically as follows:

[0053] The power management module 10 is respectively connected to the main control module 20, the voltage monitoring module 30, the current monitoring module 40 and the electric operating mechanism module 50, and is used to provide power for the bypass cabinet intelligent control device;

[0054] Specifically, the power management module 10 is the energy core of the device and is responsible for providing a stable power supply for the entire bypass cabinet intelligent control device. Specifically, it may include an AC-DC converter and a DC-DC buck converter. The AC-DC converter converts the AC power supply into a DC power supply, while the DC-DC buck converter further steps down the DC power supply to meet the needs of the internal circuit.

[0055] The voltage monitoring module 20 is connected to the main control module 20 and is used to monitor the voltage status inside the bypass cabinet in real time through an isolation operational amplifier, and transmit the generated voltage monitoring signal to the main control module 20;

[0056] Specifically, for the voltage monitoring module 20, the module monitors the voltage status inside the bypass cabinet in real time through an isolated operational amplifier, and transmits the generated voltage monitoring signal to the main control module 40. The use of isolated operational amplifiers (such as AMC1200 and AMC1200B) can protect the isolated low-voltage circuit while detecting high voltage, ensuring the safety and stability of the system.

[0057] The current monitoring module 30 is connected to the main control module 20 and is used to monitor the current state inside the bypass cabinet in real time through the ring current transformer and transmit the generated current monitoring signal to the main control module 20;

[0058] Specifically, the current monitoring module 30 monitors the current state inside the bypass cabinet in real time through the ring current transformer, and transmits the generated current monitoring signal to the main control module 40. The current transformer detects the current in the wire, and calculates the power consumption of the resistor through the power metering chip to further determine the current value in the wire.

[0059] A main control module 40, connected to the electric operating mechanism module 40, for generating corresponding control signals according to the received voltage monitoring signals and current monitoring signals, and transmitting the control signals to the electric operating mechanism module 40;

[0060] Specifically, as the brain of the entire device, the main control module 40 is responsible for receiving monitoring signals from the voltage monitoring module 20 and the current monitoring module 30, and generating control signals according to these monitoring signals to control the electric operating mechanism module to perform corresponding operations. The main control module uses STM32F103C8T6 as the main controller, and requires an external high-speed crystal oscillator circuit, a power-on reset circuit, a startup mode selection circuit, a power decoupling circuit, and a program download circuit to ensure its normal operation.

[0061] The electric operating mechanism module 50 is used to control the closing and opening of the bypass cabinet according to the received control signal;

[0062] Specifically, the electric operating mechanism module 50 controls the closing and opening of the bypass cabinet according to the received control signal. The electric operating mechanism module includes a relay control circuit and an electric operating mechanism drive circuit, which are used to execute the closing or opening command issued by the main control module.

[0063] It can be seen that the bypass cabinet intelligent control device provided in this embodiment can monitor voltage and current without contacting the high-voltage circuit through the use of isolation amplifier circuits and current transformers, thereby improving the safety of operation; the AC-DC and DC-DC conversion of the power management module ensures the stable supply of power, while the high-speed crystal oscillator circuit and power decoupling circuit of the main control module ensure the stable operation of the main controller; the main control module can generate control signals according to the real-time monitored voltage and current states to achieve intelligent control of the bypass cabinet; through the wireless remote control receiving module, remote control of the bypass cabinet can be achieved, which improves the convenience and flexibility of operation; through the program download circuit, the main controller can be easily updated and maintained, reducing maintenance costs; the electric energy metering chip of the current monitoring module can accurately calculate the current value, which helps to improve the operating efficiency and energy management level of the power system.

[0064] Furthermore, in some embodiments, the bypass cabinet intelligent control device may further include:

[0065] The wireless remote control receiving module 60 is connected to the main control module 20 and is used to respond to the operation of the remote control bypass cabinet, generate a corresponding remote control signal and transmit it to the main control module 20, so that the main control module 20 generates a corresponding control signal according to the remote control signal.

[0066] Specifically, the wireless remote control receiving module 60 is a key component of the bypass cabinet intelligent control device, allowing operators to perform remote control at a location far away from the bypass cabinet, which is particularly useful when it is necessary to avoid direct contact with the equipment or when the equipment is located in an inaccessible location.

[0067] In a specific embodiment, the wireless remote control receiving module 60 can be a remote control, which usually has multiple buttons, each of which corresponds to a specific operation command. For example, button 1 may be used for closing operation, while button 2 is used for opening operation. The design of the remote control allows the user to control the state of the bypass cabinet through simple button operation. The main control module receives the control signals from the wireless remote control receiving module and generates corresponding control commands based on these signals, which are then sent to the electric operating mechanism module to perform the actual closing or opening operation.

[0068] It can be seen that the wireless remote control function provided in this embodiment reduces the risk of operators needing to directly contact high-voltage equipment, thereby improving the safety of operation; operators can control the equipment from a distance, which is particularly useful in emergency situations or when the equipment is located in an inaccessible location; through simple button operations, users can easily control the status of the bypass cabinet without complicated operating procedures; the wireless remote control function allows the bypass cabinet to be controlled without a physical connection, greatly expanding the scope of control; the wireless remote control function reduces the need for on-site operation, thereby reducing maintenance costs and time; through wireless signal transmission, the risk of signal transmission failure due to physical connection problems can be reduced; the wireless remote control function makes it easier to integrate the bypass cabinet intelligent control device into the smart grid system to achieve remote monitoring and control.

[0069] Further, in some embodiments, the power management module 10 may specifically include a power conversion circuit, and the power conversion circuit includes an AC-DC converter and a DC-DC buck converter;

[0070] AC-DC converters are used to convert AC power into DC power.

[0071] The DC-DC step-down converter is used to step down the DC power supply for use by the internal circuits of the bypass cabinet.

[0072] Specifically, the power management module in this embodiment may specifically include a power conversion circuit, which is responsible for providing a stable and reliable power supply; the power conversion circuit includes an AC-DC converter and a DC-DC buck converter, and the AC-DC converter is responsible for converting the alternating current power (AC) into a direct current power (DC), which is the first step of the power management module, ensuring that the alternating current obtained from the external power grid can be used by the DC circuit inside the device. The power conversion circuit includes an AC-DC converter and a DC-DC buck converter. The AC-DC converter is usually composed of a rectifier and a filter to convert alternating current into direct current. The DC-DC buck converter can use switching regulator technology, such as a buck, boost, or buck-boost converter.

[0073] AC-DC conversion process: During the AC-DC conversion process, the AC power is first converted into pulsating DC power through a rectifier, and then the AC component is removed through a filter to obtain a smoother DC power.

[0074] DC-DC step-down process: During the DC-DC step-down process, the switching regulator converts a higher DC voltage into a lower DC voltage through fast switching action in conjunction with components such as inductors and capacitors, while providing a stable output.

[0075] In addition, the design of the power management module needs to consider efficiency, stability and electromagnetic compatibility (EMC). For example, the design can include a fuse (F1) to provide overcurrent protection, and EMC components to reduce electromagnetic interference; the power conversion circuit can include overvoltage, overcurrent and short circuit protection to ensure the safety of the bypass cabinet intelligent control device in the event of power abnormalities; after AC-DC conversion, the DC voltage obtained may be too high and not suitable for direct supply to the internal circuit. The role of the DC-DC buck converter is to reduce the higher DC voltage to a voltage level suitable for the internal circuit.

[0076] In a specific embodiment, the power supply has two parts, namely, using external AC220V power supply and internal DC24V power supply. When using 220V power supply, the DC24V lithium battery is charged. When using AC220V power supply, AC-DC conversion is first required to power the subsequent circuit. The power conversion circuit is as follows Figure 2 As shown, F1 is a fuse and U3 is an AC-DC power module, which can convert AC220V to DC24V. The regional components are for EMC applications to reduce the output ripple of the power module. When using DC24V power supply (the same applies after AC-DC conversion), it is still necessary to step down the voltage. The step-down circuit is as follows Figure 3 As shown, there are two steps to reduce the voltage, 24V to 5V, and the voltage used by MCU is 3.3V, so 5V also needs to be reduced to 3.3V. R6 and R9 determine the output voltage of the step-down circuit U7, and the calculation formula is (R6 / R9+1)*0.75. U8 is a positive voltage regulator, with an input voltage of 5V and an output voltage of 3.3V.

[0077] It can be seen that in this embodiment, through AC-DC conversion and DC-DC step-down, the power management module ensures that the bypass cabinet intelligent control device can obtain stable and appropriate power supply; the design of the power management module allows the device to adapt to different power supply environments, whether it is AC or DC input; the protection measures in the power management module help prevent power anomalies from damaging the device, thereby improving the safety of the system; through EMC design, the electromagnetic interference generated during the power conversion process is reduced, and the reliability and stability of the system are improved; the efficient power conversion and step-down process reduces energy loss and improves energy utilization efficiency; the modular design makes the power management module easy to maintain and upgrade, which helps to extend the service life of the device.

[0080] The voltage divider circuit is used to reduce the high-voltage side voltage to the input range of the isolation amplifier circuit.

[0081] Specifically, the voltage monitoring module 20 in this embodiment may specifically include an isolation amplifier circuit and a voltage divider circuit, wherein the isolation amplifier circuit is the core part of the voltage monitoring module, and an isolation amplifier (such as AMC1200 and AMC1200B) is used to isolate the high-voltage circuit and the low-voltage circuit to prevent the high voltage from damaging the low-voltage circuit; the isolation amplifier circuit uses a precision isolation amplifier (such as AMC1200 and AMC1200B), and the output and input circuits of these amplifiers are separated by a silicon dioxide (SiO2) barrier, which has a strong anti-magnetic interference ability, and the isolation amplifier circuit can effectively isolate the high-voltage and low-voltage circuits, protecting the low-voltage circuit from the high voltage. The voltage divider circuit is used to reduce the high-voltage side voltage to the input range of the isolation amplifier circuit to ensure that the input signal is within a safe range. The voltage divider circuit is usually composed of a series of resistors, and the high-voltage side voltage is reduced to the input range of the isolation amplifier circuit through the voltage divider effect of the resistor. The design of the voltage divider circuit needs to consider the voltage divider ratio, accuracy and stability.

[0082] In addition, the voltage monitoring module needs to have high accuracy to ensure that the monitored voltage value is accurate. This is usually achieved by selecting high-precision isolation op amps and voltage divider resistors. The voltage monitoring module needs to work stably under various environmental conditions, including temperature, humidity, and electromagnetic interference. This is usually achieved through circuit design and component selection. The use of isolation op amp circuits can effectively prevent high voltage from damaging low voltage circuits and improve system safety.

[0083] In a specific embodiment, voltage detection uses an isolation amplifier, such as Figure 4As shown in the figure, while detecting high voltage, protecting the isolated low voltage circuit, AMC1200 and AMC1200B are precision isolation amplifiers, whose output and input circuits are separated by a silicon dioxide (SiO2) barrier, which has strong anti-magnetic interference ability. When inputting high voltage, a series of resistors are required to divide the voltage before inputting the isolated op amp.

The current transformer is the core component of the current monitoring module, which can safely monitor high current without directly contacting the wire. Through the current transformer, the current in the wire can be measured without disconnecting the circuit. The electric energy metering chip is used to calculate the voltage and current on the secondary side of the current transformer to determine the current value on the primary side of the current transformer. The electric energy metering chip is responsible for processing the voltage signal generated by the current transformer and calculating the actual current value. These chips usually have high precision and high stability and can accurately measure current. The design of the current monitoring module needs to consider the measurement accuracy to ensure the stable operation of the power system and the effective management of energy. The module needs to work stably under various environmental conditions, including temperature, humidity and electromagnetic interference. The use of current transformers can effectively prevent direct contact with high currents and improve the safety of the system.

[0097] Specifically, the main control module in this embodiment may include an external high-speed crystal oscillator circuit, a power-on reset circuit, a startup mode selection circuit, a power decoupling circuit and a program download circuit; wherein,

[0098] The external high-speed crystal oscillator circuit provides an accurate clock signal for the main controller chip to ensure its stable operation. The crystal oscillator circuit provides a stable clock signal, which is the key to ensure the accurate operation of the main controller. The frequency stability and accuracy of the crystal oscillator directly affect the response speed and accuracy of the entire system. The power-on reset circuit is used to initialize the main controller chip when the power is turned on to ensure that the system starts running from a known state; the power-on reset circuit ensures that the main controller can start running from a certain state when the power is turned on to prevent system errors caused by unstable power supply.

The electric operating mechanism may include a motor that rotates according to the instructions of the drive circuit, thereby driving mechanical components (such as the closing or opening operation of the circuit breaker). Relay control circuits and electric operating mechanism drive circuits require precise control logic to ensure accuracy and safety of operation. Usually implemented through software programming to ensure that the correct action can be performed after receiving the control signal.
