The mounting plate 301 is precisely machined and firmly fixed to the top of the backing plate 107, providing a stable mounting foundation for other components. The mounting holes 302 are evenly distributed on the surface of the mounting plate 301. The function of these mounting holes 302 is to more firmly mount related components on the mounting plate 301 through screws or other fixing parts, ensuring the accurate relative position between components. The touch screen 303 is carefully set on the top of the mounting plate 301. It uses a high-resolution and sensitive touch screen material, providing an intuitive and convenient operation interface for users. Users can easily select various functions, set parameters, and view data by touching the screen. The mechanical knob 304 is rotationally connected to the top of the mounting plate 301 through a precise rotating shaft structure. It is commonly used for parameter settings that require precise adjustment, such as adjusting the measurement range, sensitivity, etc. By rotating the mechanical knob 304, users can continuously and precisely adjust related parameters to meet the requirements of different measurement scenarios. The multi-mode interface 305 is reasonably set on the top of the mounting plate 301. It integrates various common interface types, such as USB interfaces, HDMI interfaces, network cable interfaces, etc., enabling the instrument to easily transfer data and connect with various external devices to achieve functions such as data sharing and remote control.

The warning light 308 is set on the top of the mounting plate 301. It usually uses LED lights of different colors to indicate the working state of the instrument, such as the power state, data transmission state, measurement abnormal state, etc. When the instrument is in different working states, the warning light 308 will display the corresponding color or flashing mode, facilitating users to quickly understand the operation of the instrument.

[0028] The control unit consists of an IoT master control center 311, an electromagnetic drive actuator 312, a piezoelectric fine-tuning actuator 313, a wire harness access module 314, a multi-dimensional sensor array 315, a power supply switching module 316, a series circuit 317, and a flashing light circuit board 318. The IoT master control center 311, as the core component of the control unit, is firmly fixed and connected to the bottom of the mounting plate 301. It is equipped with an AI dynamic compensation algorithm. By performing real-time dynamic analysis on a large amount of data collected by the multi-dimensional sensor array 315, it can accurately identify various errors and interference factors during the measurement process and perform intelligent compensation in a timely manner. For example, when measuring parameters such as voltage and current, when the measurement data deviates due to external electromagnetic interference or internal circuit noise of the instrument, the AI dynamic compensation algorithm can quickly calculate the compensation value and correct the measurement result, thereby improving the accuracy and stability of the instrument measurement and achieving more intelligent and efficient control and adjustment functions. The touch screen 303 and the mechanical knob 304 are electrically connected to the IoT master control center 311 through a dedicated circuit. This enables users to input control signals to the IoT master control center 311 through the operation instructions on the touch screen 303 and the adjustment actions of the mechanical knob 304. After receiving these signals, the IoT master control center 311 will accurately control and adjust the various functions of the instrument according to the preset programs and algorithms to achieve the operations expected by the user. The electromagnetic drive actuator 312 is firmly fixed and connected to the bottom of the mounting plate 301. It uses the principle of electromagnetic induction to generate driving force and can quickly and accurately execute the action instructions issued by the IoT master control center 311. For example, when it is necessary to switch the measurement circuit or adjust the position of certain mechanical components, the electromagnetic drive actuator 312 can respond quickly and drive the relevant components to complete the action through electromagnetic force, ensuring the fast and stable function switching of the instrument. The piezoelectric fine-tuning actuator 313 is also fixed and connected to the bottom of the mounting plate 301. It works based on the characteristics of piezoelectric materials. When excited by an electrical signal, the piezoelectric material will produce a tiny deformation, thereby achieving fine adjustment of certain parameters of the instrument. For example, in the case of extremely high requirements for measurement accuracy, the piezoelectric fine-tuning actuator 313 can fine-tune components such as capacitors and resistors in the measurement circuit according to the instructions of the IoT master control center 311 to achieve higher measurement accuracy. The wire harness access module 314 is firmly fixed and connected to the bottom of the mounting plate 301. It is the centralized access point for various wire harnesses inside the instrument. Through reasonable wiring design, the wire harnesses from different components are neatly connected to the wire harness access module 314 to achieve electrical connection and signal transmission between components. The multi-dimensional sensor array 315 is closely fixed and connected to the side of the wire harness access module 314. It integrates multiple sensors such as voltage, current, harmonics, impedance, temperature, and EMI. These sensors use advanced sensing technologies and can simultaneously and real-time collect various electrical parameters in the circuit and ambient parameters. For example, the voltage sensor can accurately measure the voltage value in the circuit,The current sensor can accurately detect the magnitude of the current, the harmonic sensor can analyze the harmonic components in the circuit, the impedance sensor can measure the impedance characteristics of circuit components, the temperature sensor can monitor the temperature of key parts inside the instrument in real time, and the EMI sensor is used to detect electromagnetic interference. Through the integration of multiple sensors, it provides rich and accurate data support for the instrument to achieve multi-functional measurement and intelligent control. The power supply switching module 316 is fixedly connected to the bottom of the mounting plate 301. It can intelligently switch different power supply modes according to the working state and power demand of the instrument. For example, when the instrument is connected to an external power supply, the power supply switching module 316 can stably distribute the power to each component; when the external power supply fails or needs to be switched to a backup power supply, the power supply switching module 316 can quickly and reliably switch the power supply to the backup battery or other backup power supply devices to ensure that the normal operation of the instrument is not affected. The series circuit 317 uses high-quality wires and is firmly fixedly connected to the surfaces of the multi-dimensional sensor array 315, the power supply switching module 316, and the Internet of Things main control center 311. It is responsible for transmitting various signals and power between these components. Through reasonable circuit layout and design, it ensures the stability and accuracy of signal transmission, and avoids signal interference and power loss. The flashing light circuit board 318 is fixedly connected to the bottom of the mounting plate 301. It more intuitively shows different working states and important information of the instrument to the user by controlling the flashing mode and color change of the indicator light 308. For example, when the instrument detects an abnormal situation, the flashing light circuit board 318 can control the indicator light 308 to flash rapidly in red to attract the user's attention. When the instrument is in a normal working state, the indicator light 308 may display a stable green light. Through the coordinated work of these components, comprehensive functions such as intelligent control, parameter adjustment, data acquisition, and status indication of the instrument are realized, enabling this electrical instrument to meet various complex measurement and control requirements in practical applications.,
