[0037] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0038] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0039] The embodiment of the present invention provides an electric field measurement system suitable for different application scenarios of new power systems, such as Figure 1 As shown, the electric field measurement system includes a sensing module 100, a signal transmission and processing module 200 and an energy supply module 300. The sensing module 100 is embedded and integrated inside the power equipment 400 for real-time monitoring of electric field signals; the signal transmission and processing module 200 is connected to the sensing module 100 for signal transmission and processing; the energy supply module 300 includes a permanent magnet resonance coupling unit 310 and an energy management unit 320. The permanent magnet resonance coupling unit 310 is electrically connected to the energy management unit 320 for extracting energy from the ambient electromagnetic field and transmitting it to the energy management unit. The energy management unit 320 is electrically connected to the sensing module 100 and the signal transmission and processing module 200 for providing a power source for the sensing module 100 and the signal transmission and processing module 200.

[0040] The sensing module 100 is used to realize real-time monitoring of electric field signals. The sensing module 100 is directly integrated into the power equipment 400 through embedded design, and monitors the electric field signals around the equipment in real time. Its core is a micro electric field sensor based on organic semiconductor materials, which uses the electrochemical doping effect to achieve high-sensitivity detection. The electric field generated when the power equipment is in operation acts on the organic semiconductor layer of the sensor, causing changes in the conductivity of the material (electrochemical doping effect), which is converted into an electrical signal. The sensing module 100 converts the electric field signal into a current signal and outputs it to the signal transmission and processing module 200. The embedded design reduces external interference and improves monitoring accuracy; miniaturization (<1cm 2 ) and low power consumption (<1mW) adapt to complex installation environments; support multi-point distributed deployment, and cover wide-area electric field distribution through sensor arrays.

[0041] The signal transmission and processing module 200 is used to realize signal transmission and optimization. It receives the original signal from the sensor module, performs pre-processing, and then transmits it to the monitoring platform via wireless technology.

[0042] The energy supply module 300 is used to achieve self-sufficient energy management. The permanent magnetic resonance coupling unit 310 extracts energy from the ambient electromagnetic field and provides continuous power to the sensing module (100) and the signal transmission module (200) through the energy management unit 320, thereby overcoming the limitations of traditional energy supply methods in complex environments and achieving efficient energy self-sufficiency of the system. The energy supply module ensures long-term reliable operation of the entire measurement system in various application scenarios through coordinated optimization with the sensing module and the signal transmission module.

[0043] The system requires no external power supply and relies entirely on ambient energy, reducing maintenance costs. Its modular design adapts to various scenarios such as power equipment, transmission lines, and industrial environments. The combination of permanent magnet resonant coupling and intelligent energy management achieves an energy utilization rate of >50% and a long-distance transmission of 10 meters.

[0044] In some embodiments, as Figure 2 As shown, the sensing module 100 includes an organic semiconductor layer 110 , an electrode layer 120 and an encapsulation layer 130 . The performance of the organic semiconductor layer 110 is modulated by chemical modification.

[0045] Specifically, the sensor module 100 uses photolithography technology to prepare a micro electric field sensor, and achieves high-sensitivity detection of electric field signals through the electrochemical doping effect. The sensor structure includes an organic semiconductor layer, an electrode layer, and an encapsulation layer, wherein the organic semiconductor layer is chemically modified to achieve performance modulation. The sensor module 100 is flexible, small in size (less than 1 cm 2 ), low drive voltage (less than 1V), low power consumption (less than 1mW), and high sensitivity (greater than 0.1V / m). The sensor module 100 adopts an embedded design and can be directly integrated into the power equipment 400 to monitor the electric field distribution of the equipment in real time. In practical applications, the sensor module supports multi-point distributed monitoring, building a wider coverage electric field sensing network through the sensor array. The sensor array uses multi-point calibration and signal fusion technology to achieve multi-dimensional electric field data collection in complex environments.

[0046] In some embodiments, as Figure 3 As shown, the signal transmission and processing module 200 includes a short-distance transmission unit 210, a long-distance transmission unit 220 and a signal processing unit 230. The signal output end of the sensing module 100 is connected to the signal input end of the signal processing unit 230 to feed the electric field signal monitored by the sensing module 100 to the signal processing unit 230. The signal processing unit 230 is used to process the electric field signal to obtain a processed signal. The signal processing unit 230 is electrically connected to the short-distance transmission unit 210 and the long-distance transmission unit 220, and is used to select the short-distance transmission unit 210 and / or the long-distance transmission unit 220 to wirelessly transmit the processed signal according to a preset signal transmission method.

[0047] For example, the short-range transmission unit 210 can use Bluetooth Low Energy (BLE) and Zigbee technology (e.g., using a Bluetooth module or a Zigbee module), which is suitable for internal or close-range monitoring of power equipment. BLE technology has low power consumption (less than 10mW), high transmission rate (1Mbps), and strong anti-interference capabilities; Zigbee technology is suitable for multi-point networking, supports multi-hop transmission, and has a coverage range of up to 100 meters.

[0048] The long-distance transmission unit 220 uses LoRa and NB-IoT technologies (e.g., a LoRa module and / or an NB-IoT module) and is suitable for power transmission lines or wide-area environmental monitoring scenarios. LoRa technology offers ultra-low power consumption (less than 50mW) and long-distance transmission capabilities (up to 10 kilometers). NB-IoT technology is suitable for urban environments, supporting high-density device access and stable transmission.

[0049] In some embodiments, as Figure 4 As shown, signal processing unit 230 includes a preprocessing subunit 231 and a modulation subunit 232. Preprocessing subunit 231 includes a low-noise amplifier 2311 and a bandpass filter 2312. Low-noise amplifier 2311, bandpass filter 2312, and modulation subunit 232 are connected in sequence to perform filtering and modulation processing on the electric field signal to obtain a processed signal. Low-noise amplifier 2311 is only used in long-distance wireless transmission. One advantage of the sensor module in this embodiment is that the output current signal can reach the mA level, eliminating the signal amplification process in short-distance transmission.

[0050] In this embodiment, the signal processing unit 230 is further designed to improve the reliability and efficiency of wireless transmission. Specifically, the signal quality can be improved by the low noise amplifier 2311 and the bandpass filter 2312. The modulation subunit 232 can adopt frequency modulation (FSK) or phase modulation (PSK) technology to improve the anti-interference ability and transmission efficiency of the signal. For example, for long-distance transmission, combined with spread spectrum technology (such as LoRa's CSS modulation), the anti-interference performance of the signal is further enhanced. The signal transmission module adopts a modular design, which allows users to flexibly select a transmission scheme according to actual needs. At the same time, the module supports seamless integration with the existing power system monitoring platform and realizes data interaction through standard communication protocols.

[0051] In some embodiments, as Figure 5As shown, the permanent magnet resonant coupling unit 310 includes a resonant coil 311, a permanent magnet 312 and an energy harvesting circuit 313; wherein, the resonant coil 311 is used to capture the alternating electromagnetic field energy in the environment, and the permanent magnet 312 includes a plurality of uniformly distributed magnets 3121 to enhance the strength and uniformity of the magnetic field and expand the effective range of energy transmission. The energy harvesting circuit 313 is connected to the resonant coil 311 and is used to harvest the alternating electromagnetic field energy captured by the resonant coil 311.

[0052] In this embodiment, the resonant coil 311 can utilize multilayer winding technology and high-permeability materials (ferrite) to increase the coil's resonant frequency (50 Hz to 1 kHz) and energy collection efficiency (greater than 50%). By optimizing the shape and arrangement of the magnets 3121 included in the permanent magnet 312, the magnetic field strength and uniformity are enhanced, improving the stability and distance of energy transmission (up to 10 meters).

[0053] In some embodiments, as Figure 5 As shown, the energy harvesting circuit 313 includes a resonant matching circuit 3131, a rectifier circuit 3132 and a DC-DC converter 3133; wherein, the resonant matching circuit 3131 is used to ensure that the resonant frequency of the coil is consistent with that of the ambient electromagnetic field, the rectifier circuit 3132 is used to convert AC power into DC power, and the DC-DC converter 3133 is used to achieve stable voltage output.

[0054] In some embodiments, as Figure 6 As shown, the energy management unit 320 includes an energy storage device 321 and an energy optimizer 322. The energy storage device 321 is electrically connected to the permanent magnet resonance coupling unit 310 and the sensor module 100. The energy optimizer 322 is connected to the energy storage device 310 and is used to dynamically adjust the energy collection and distribution strategy according to environmental energy fluctuations and system load requirements.

[0055] In this embodiment, a supercapacitor may be used as the energy storage device 321 . The supercapacitor has the characteristics of high energy density and long cycle life, and supports long-term operation of the system.

[0056] In some embodiments, as Figure 7 As shown, the energy supply module 300 further includes a multi-source energy harvesting unit 330 , which is electrically connected to the energy management unit 320 .

[0057] Specifically, multi-source energy harvesting unit 330 includes a photovoltaic energy harvesting subunit 331 and a thermoelectric energy harvesting subunit 332. By way of example only, photovoltaic energy harvesting subunit 331 includes a micro-photovoltaic panel, and thermoelectric energy harvesting subunit 332 includes a thermoelectric generator. In bright sunlight, photovoltaic energy harvesting subunit 331 harvests solar energy using the micro-photovoltaic panel, supplementing the energy supply provided by the permanent magnetic resonance coupling technology. In high-temperature environments, thermoelectric energy harvesting subunit 332 converts temperature difference energy into electrical energy using the thermoelectric generator, achieving multi-source complementary power supply.

[0058] When the energy supply module 300 further includes a multi-source energy harvesting unit 330, the specific steps for dynamically adjusting the energy harvesting and distribution strategy according to environmental energy fluctuations and system load requirements are as follows:

[0059] Step 1: Data collection and monitoring.

[0060] The following parameters are collected in real time: electromagnetic field strength (through the voltage / current sensor of the permanent magnet resonant coupling unit), light intensity (output current of the photovoltaic panel), temperature gradient (temperature difference voltage across the thermoelectric generator), ambient electromagnetic field frequency (used for resonant matching circuit frequency calibration), sensor module power consumption (such as sampling frequency, number of sensor array activations), signal transmission status (transmission mode, data packet size and frequency of the wireless module), and energy storage device power (voltage / remaining capacity of the supercapacitor).

[0061] Step 2: Data processing and priority determination.

[0062] Energy input assessment: Calculates the current total energy input rate, including permanent magnet resonant coupling power, photovoltaic power generation power, and thermoelectric power generation power.

[0063] The load requirements are classified as follows:

[0064] Key load: basic sampling of the sensor module (priority 1);

[0065] Secondary load: low-frequency data upload of the signal transmission module (priority 2);

[0066] Non-essential loads: high-frequency data transmission or redundant calculations (priority 3).

[0067] The energy storage status is classified as follows:

[0068] Sufficient (supercapacitor charge > 80%): high power output is allowed;

[0069] Medium (30% ≤ power ≤ 80%): Limit non-essential loads;

[0070] Insufficient (battery level < 30%): Only critical loads are maintained.

[0071] Step 3: Dynamically adjust the strategy.

[0072] Energy harvesting optimization:

[0073] Permanent magnet resonant coupling control: If the ambient electromagnetic field strength decreases, the resonant frequency is automatically adjusted (via variable capacitors or inductors) to match the remaining frequency band energy; the magnetic field enhancement mode of the multi-magnet array is enabled (activated only in high energy storage state when additional power consumption is required).

[0074] Photovoltaic panel angle adjustment (motor-driven): Dynamically adjust the direction of the photovoltaic panel based on light sensor data to maximize light energy capture efficiency.

[0075] TEG temperature difference optimization: In high temperature difference scenarios, the heat dissipation channel is closed to improve the thermoelectric conversion efficiency.

[0076] Energy allocation strategy:

[0077] Mode 1: When there is sufficient energy, the sensor module and signal transmission module are powered first; the surplus energy is stored in the supercapacitor; if the energy storage is full, non-essential loads (such as historical data feedback) are activated.

[0078] Mode 2: Energy balance, allocating energy in order of priority: critical load → secondary load; prohibiting non-essential loads from running; and fine-tuning resonance parameters in real time to maintain input-output balance.

[0079] Mode 3: In case of energy shortage, the system switches to energy storage power supply and limits the usage time of secondary loads; reduces the sampling frequency of the sensor module (e.g., from 100Hz to 10Hz); if the energy storage is continuously insufficient, a low-power sleep mode is triggered (maintaining only basic monitoring).

[0080] Step 4: Feedback and adaptive optimization.

[0081] Short-term feedback: Updates the matching degree between energy input and load demand every 1 second; dynamically adjusts the output voltage of the DC-DC converter to avoid energy waste.

[0082] Long-term optimization: Train machine learning models using historical data to predict environmental energy fluctuations (such as peak and valley cycles in grid load); and adaptively adjust priority strategies (for example, enabling energy storage in advance during predicted low electromagnetic field periods).

[0083] Step 5: Exception handling mechanism.

[0084] Sudden energy interruption: If the ambient electromagnetic field drops suddenly (such as equipment shutdown), it will immediately switch to energy storage power supply and send a warning signal; secondary loads will be forced to shut down and only critical functions will be maintained.

[0085] Load mutation: If the signal transmission module needs to send an emergency alarm (such as an abnormal electric field), its priority is temporarily increased to the highest and the reserve energy is called upon.

[0086] Through refined control and intelligent decision-making, the above process achieves the optimal balance between energy collection and distribution in complex environments, providing sustainable operation guarantee for the passive monitoring system.

[0087] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
