On existing power transmission lines, the main environmental energy that can be harvested includes electric field energy, solar energy, and conductor magnetic field energy. Among these, solar energy and conductor magnetic field energy harvesting technologies have been developed relatively long and are relatively mature, but they are easily affected by external environmental interference. For example, on cloudy or rainy days, solar energy output is extremely low, making it difficult to power monitoring devices. Also, at night, reduced electricity consumption by users leads to lower current levels in the transmission lines, significantly limiting the collection of conductor magnetic field energy. Although electric field energy has advantages such as energy stability and high sustainability, its output power is low, making it difficult to meet long-term power supply needs.

[0065] This application provides a power supply method based on multi-source energy, such as... Figure 1 As shown, the method includes:

[0066] 101. Monitor the energy data in the first energy storage device in real time.

[0067] The first energy storage device is used to store electrical energy converted from solar energy and / or magnetic field energy of a conductor, such as a lithium battery. In this embodiment, the energy data in the first energy storage device can be monitored in real time using sensors built into the energy storage device or external sensors.

[0068] It should be noted that, since solar energy and conductor magnetic field energy harvesting technologies have been developed for a relatively long time, are relatively mature, and have high energy density, these two types of environmental energy can be effectively utilized as the main energy source for the load to achieve energy saving. However, these two environments are easily affected by sunlight and current, so they can be stored and released to the load when solar energy and conductor magnetic field energy are insufficient.

[0069] 102. If the energy data is greater than the preset energy threshold, control the first energy storage device to enter the power supply state.

[0070] The preset energy threshold is used to characterize the minimum energy threshold stored when the first energy storage device can enter the power supply state. In this embodiment, if the energy data in the first energy storage device is greater than the preset energy threshold, the power supply switch of the first energy storage device is closed to form a closed loop between the first energy storage device and the load, so that the first energy storage device enters the power supply state and provides electrical energy to the load, that is, it uses the solar energy stored in the lithium battery and / or the electrical energy converted from the magnetic field energy of the wire to power the load.

[0071] 103. If the energy data is less than the preset energy threshold, control the second energy storage device to enter the power supply state.

[0072] In this embodiment, the energy stored in the first energy storage device and the energy stored in the second energy storage device originate from different energy sources. The first energy storage device stores electrical energy converted from solar energy and / or magnetic field energy of conductors, such as lithium batteries. The second energy storage device stores electrical energy converted from electric field energy, such as capacitors (equivalent to high internal resistance capacitive power supplies). In this embodiment, if the energy data in the first energy storage device is greater than a preset energy threshold, the power supply switch of the second energy storage device is closed, forming a closed loop between the second energy storage device and the load. This allows the second energy storage device to enter a power supply state, providing electrical energy to the load, i.e., using the electrical energy converted from the electric field energy stored in the capacitor to power the load.

[0073] It should be noted that electric field energy has the advantages of energy stability and high continuity, and can resist interference from the external environment to achieve continuous power output. However, due to the low output power, it cannot reach the power required to drive the load. Therefore, capacitors can be used to store the electrical energy converted from electric field energy. When the power required to drive the load is reached, it can be released to power the load. This allows for intermittent power supply to the load when solar energy and magnetic field energy of the conductor are insufficient, and when the first energy storage device is insufficient, so as to ensure the reliability of power supply.

[0074] Compared with the prior art, the embodiments of this application comprehensively utilize the energy provided by multiple energy sources to power the load, thereby achieving uninterrupted power supply to the load unit and ensuring the power supply reliability of the power supply system.

[0075] For further explanation and limitation, in the embodiments of this application, if the energy data is less than a preset energy threshold, the second energy storage device is controlled to enter the power supply state. Specifically, this includes: if the first energy data is less than the first preset energy threshold and the second energy data is greater than the second preset energy threshold, the second energy storage device is controlled to enter the continuous power supply state; if the first energy data is less than the first preset energy threshold and the second energy data is less than the second preset energy threshold, the second energy storage device is controlled to enter the intermittent power supply state.

[0076] The first energy data is used to characterize the energy data in the first energy storage device, and the second energy data is used to characterize the energy data in the second energy storage device. The first preset energy threshold is used to characterize the minimum energy threshold stored when the first energy storage device can enter the power supply state, that is, the minimum energy stored when the lithium battery can provide power to the load. The second preset energy threshold is used to characterize the minimum energy threshold stored when the second energy storage device can enter the power supply state, that is, the minimum energy stored when the capacitor can provide power to the load.

[0077] Specifically, if the energy content in the first energy storage device is less than the minimum energy storage threshold for it to enter the power supply state, and the energy content in the second energy storage device is greater than the minimum energy storage threshold for it to enter the power supply state, then the second energy storage device is controlled to continuously supply power to the load; if the energy content in the first energy storage device is less than the minimum energy storage threshold for it to enter the power supply state, and the energy content in the second energy storage device is also less than the minimum energy storage threshold for it to enter the power supply state, then the power supply to the load is temporarily stopped. When the energy content in the second energy storage device is greater than the minimum energy storage threshold for it to enter the power supply state, the second energy storage device is controlled to supply power to the load, i.e., intermittent power supply state, thereby ensuring the reliability of power supply. For example, if the solar energy and / or the electrical energy converted from the magnetic field energy of the conductor stored in the lithium battery cannot meet the power supply demand, but the electrical energy converted from the electric field energy stored in the capacitor can meet the power supply demand, the control capacitor provides continuous and uninterrupted power supply to the load; if the solar energy and / or the electrical energy converted from the magnetic field energy of the conductor stored in the lithium battery cannot meet the power supply demand, and the electrical energy converted from the electric field energy stored in the capacitor also cannot meet the power supply demand, the power supply to the load is temporarily stopped, and the control capacitor enters a charging state. When the electrical energy converted from the electric field energy stored in the capacitor meets the power supply demand, the control capacitor resumes power supply to the load.

[0078] For further explanation and limitation, in the embodiments of this application, controlling the first energy storage device to enter the power supply state specifically includes: controlling the first switch to close and the second switch to open, so that a closed loop is formed between the first energy storage device and the load device; and acquiring electric field energy and storing it in the second energy storage device.

[0079] The first switch controls the connection between the first energy storage device and the load, i.e., the connection of the lithium battery power supply line; the second switch controls the connection between the second energy storage device and the load, i.e., the connection of the capacitor power supply line. Optionally, the switching of the first and second switches can be achieved by a hysteresis comparator and an analog switch. The hysteresis comparator has strong anti-interference capabilities, which can improve the reliability of the switching operation; the analog switch has advantages such as low power consumption, high speed, no mechanical contacts, small size, and long service life. The choice between the two can be made depending on the specific application scenario, and this application embodiment does not impose specific limitations.

[0080] Specifically, by controlling the closing of the switch between the first energy storage device and the load, a closed circuit is formed between the first energy storage device and the load, thus entering a power supply state; simultaneously, by controlling the opening of the switch between the second energy storage device and the load, an open circuit is formed between the second energy storage device and the load, and electric field energy is acquired and stored in the second energy storage device, thus entering a charging state. For example, closing the switch between the lithium battery and the load allows the lithium battery to supply power to the load, while simultaneously opening the switch between the capacitor and the load allows electric field energy to be acquired, thus entering a charging state.

[0081] For further explanation and limitation, in the embodiments of this application, controlling the second energy storage device to enter the power supply state specifically includes: controlling the second switch to close and the first switch to open, so that a closed loop is formed between the second energy storage device and the load device; acquiring solar energy and / or conductor magnetic field energy and storing it in the first energy storage device.

[0082] Specifically, by controlling the closing of the switch between the second energy storage device and the load, a closed circuit is formed between the second energy storage device and the load, thus entering a power supply state; simultaneously, by controlling the opening of the switch between the first energy storage device and the load, an open circuit is formed between the first energy storage device and the load, and solar energy and / or magnetic field energy from the conductor are acquired and stored in the first energy storage device, thus putting it into a charging state. For example, closing the switch between the capacitor and the load allows the capacitor to supply power to the load, while simultaneously opening the switch between the lithium battery and the load allows solar energy and / or magnetic field energy from the conductor to be acquired, thus putting it into a charging state.

[0083] Preferably, as one possible implementation, in this embodiment of the application, acquiring electric field energy and storing it in a second energy storage device specifically includes: acquiring electric field energy, controlling the electric field energy to pass sequentially through an impedance matching device and a first AC / DC conversion device, and then storing it in the second energy storage device.

[0084] Among them, the first AC / DC conversion device is used to characterize the AC / DC conversion device required for converting electric field energy.

[0085] It is understandable that the principle of electric field energy harvesting is capacitive voltage division, which can be equivalent to a capacitive power source with a large internal resistance. According to the maximum power transmission theorem, impedance matching is required to achieve a larger power output. For example, a transformer can be used to achieve impedance matching. Furthermore, since the electric field energy is alternating current, an AC-DC conversion device is needed to convert the AC to DC before storing it in a capacitor.

[0086] Preferably, as one possible implementation, in this embodiment of the application, acquiring solar energy and / or conductor magnetic field energy and storing it in the first energy storage device specifically includes: acquiring solar energy, controlling the solar energy to pass sequentially through a maximum power point tracking solar control device and a first voltage regulator, and then storing it in the first energy storage device; and / or, acquiring conductor magnetic field energy, controlling the conductor magnetic field energy to pass sequentially through a second AC / DC conversion device and a second voltage regulator, and then storing it in the first energy storage device.

[0087] The first voltage regulator is used to regulate the voltage of the electrical energy converted from solar energy; the second voltage regulator is used to regulate the voltage of the electrical energy converted from the magnetic field energy of the conductor; and the second AC / DC converter is used to characterize the AC / DC converter required to convert the magnetic field energy of the conductor.

[0088] Understandably, the magnetic field energy harvesting of conductors is based on the principle of electromagnetic induction, and the output is alternating current. It is necessary to use an AC / DC converter to convert the AC to DC and then store it in a lithium battery. The solar energy output is a DC signal. In order to maximize energy harvesting, a maximum power point tracking solar controller is introduced.

[0089] Preferably, in this embodiment of the application, in order to extend the service life of the first energy storage device, the method further includes: if the first energy data is detected to be greater than a third preset energy threshold, then controlling the first energy storage device to stop energy storage operation; if the first energy data is detected to be less than a fourth preset energy threshold, then controlling the first energy storage device to stop power supply operation.

[0090] The third preset energy threshold is used to characterize the maximum energy that the first energy storage device can store while ensuring its safety; the fourth preset energy threshold is used to characterize the minimum energy that the first energy storage device can store while ensuring its safety.

[0091] Specifically, if the first energy data is detected to be greater than the maximum energy that the first energy storage device (such as a lithium battery) can store, the first energy storage device is controlled to stop energy storage operation, that is, overcharge protection is provided for the first energy storage device; if the first energy data is detected to be less than the minimum energy that the first energy storage device can store, the first energy storage device is controlled to stop power supply operation, that is, over-discharge protection is provided.

[0092] In specific application scenarios, circuit diagrams for power supply methods based on multi-source energy are as follows: Figure 2 As shown, AC / DC represents an AC / DC converter, DC / DC and LDO represent voltage regulators, and MPPT represents a maximum power point tracking solar control device. Specifically, when the lithium battery has sufficient charge to meet power requirements, control S2 closes, allowing the electrical energy to power the wireless sensing unit through the LDO voltage regulator. Simultaneously, control S1 opens, allowing the electric field energy to pass through the impedance matching module and the AC / DC converter before being stored in the supercapacitor. When the lithium battery cannot meet power requirements, control S1 closes, allowing the electrical energy in the supercapacitor to power the wireless sensing unit through the DC / DC voltage regulator. Simultaneously, control S2 opens, allowing the magnetic field energy to pass through the AC / DC converter, the DC / DC voltage regulator, and the solar energy through the MPPT solar control device and the DC / DC voltage regulator, all stored in the lithium battery. This ensures uninterrupted power supply to the load unit and guarantees the reliability of the power supply system.

[0093] This application provides a power supply method based on multi-source energy. First, the energy data in a first energy storage device is monitored in real time. Second, if the energy data is greater than a preset energy threshold, the first energy storage device is controlled to enter a power supply state. Finally, if the energy data is less than the preset energy threshold, a second energy storage device is controlled to enter a power supply state. The energy stored in the first and second energy storage devices originates from different energy sources. Compared with existing technologies, this application's embodiment, by comprehensively utilizing energy from multiple energy sources to power the load, can achieve uninterrupted power supply to the load unit, ensuring the reliability of the power supply system.

[0097] The power supply module 22 is used to control the first energy storage device to enter the power supply state if the energy data is greater than a preset energy threshold.

[0098] The power supply module 22 is also used to control the second energy storage device to enter the power supply state if the energy data is less than the preset energy threshold, wherein the energy stored in the first energy storage device and the energy stored in the second energy storage device are respectively from different energy sources.

[0105] Preferably, the power supply module specifically includes:

[0108] Preferably, the storage unit is specifically used for:

[0109] Electric field energy is acquired, and the electric field energy is controlled to pass through an impedance matching device and a first AC / DC conversion device in sequence before being stored in the second energy storage device.

Second, if the energy data exceeds a preset energy threshold, it controls the first energy storage device to enter a power supply state. Finally, if the energy data is less than the preset energy threshold, it controls a second energy storage device to enter a power supply state.
