Wireless power transmission technology can eliminate the need for wiring, is easy to install, can save costs, and improve the reliability and stability of the monitoring system. With the progress of technology and the reduction of costs, the application prospect of wireless power transmission technology in the field of camera power supply will be brighter. Summary of the Invention

[0008] The external power network is used to supply electrical energy to the power and information synchronous transmission system when both the photovoltaic panel and the energy storage module have insufficient power;

[0009] The power and information synchronous transmission system includes two parts: power transmission and information transmission. Among them, power transmission includes: a power transmission circuit, a power reception circuit, and a magnetic coupler. The power transmission circuit includes a power transmission controller, an inverter, and a primary resonant network. The magnetic coupler includes a transmitting coil and a receiving coil.

[0014] The intelligent switching system includes a processor and a memory storing executable instructions. The processor performs the following operations according to the executable instructions stored in the memory:

[0015] When the voltage of the photovoltaic panel is higher than the first threshold, start the photovoltaic panel to supply power to the energy storage module and the power and information synchronous transmission system;

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] In an embodiment provided by the present invention, as Figure 1 shown, a wireless uninterruptible photovoltaic energy storage camera device is provided, which includes a camera, a photovoltaic panel, an energy storage module, an external power grid, an electric energy and information synchronous transmission system, an intelligent switching system, and a wireless communication module;

[0028] In a specific implementation, the transmitting end of the electric energy and information synchronous transmission system is connected to the photovoltaic panel, the energy storage module, and the external power grid, converts the electric energy into high-frequency alternating current through an inverter and a primary resonant network, transmits it to the receiving coil through the transmitting coil of the magnetic coupler, and converts the electric energy into adjustable direct current through a rectifier and a secondary resonant network for supply to the camera. The electric energy transmitting end and the camera receiving end not only need to perform energy transmission but also need to achieve data communication. The control unit controls the flow direction and priority of the power through real-time data monitoring to ensure the stable operation of the system.

[0029] The photovoltaic panel supplies power to the electric energy and information synchronous transmission system by converting solar energy into electric energy, while the energy storage module supplies power to the electric energy and information synchronous transmission system when the photovoltaic panel has insufficient power. The external power grid supplies power to the electric energy and information synchronous transmission system when both the photovoltaic panel and the energy storage module cannot meet the power demand, providing an external power source for the camera to ensure that the device always operates without interruption.

[0030] The functions of each module are further explained as follows:

[0031] Photovoltaic panel: It is used to collect solar energy and convert it into electrical energy to supply power to the power source of the power and information synchronous transmission system. The photovoltaic cell is directly connected to the energy storage battery through the photovoltaic panel to provide a stable power input.

[0032] Energy storage module: It is used to store the excess electrical energy generated by the photovoltaic cell. When the photovoltaic cell cannot provide enough power, the energy storage battery provides additional power support to ensure the uninterrupted operation of the device.

[0033] Camera module: As the final load, relying on the support of the above power module, it realizes the continuous and stable operation of the camera.

[0034] Intelligent switching system, connected to the photovoltaic panel, energy storage module, external power grid and power emission controller, collects voltage data and makes logical judgments, and outputs the judgment results to the intelligent switching system to realize automatic switching of the power state and supply power to the power and information synchronous transmission system;

[0035] Wireless communication module, connected to the camera, is used to transmit the image or video information collected by the camera to an external device.

[0036] In an embodiment provided by the present invention, as Figure 2 shown, a flow chart of the switching control method of a wireless non-stop power supply photovoltaic energy storage camera device is provided.

[0037] Working mode: First, monitor the working state of the photovoltaic panel, the power of the energy storage module and the external power grid. When the power of the photovoltaic panel is sufficient, close switch S1 to supply power to the power and information synchronous transmission system; when the power of the photovoltaic panel is insufficient, the system automatically replenishes the power of the photovoltaic panel. If the camera power supply voltage threshold is met, the photovoltaic panel is started preferentially. If the camera power supply voltage threshold is not met, close switch S2 to start the energy storage module to supply power to the power and information synchronous transmission system. If the energy storage module also fails to meet the camera power supply voltage threshold, then close switch S3 to start the external power grid to supply power to the power and information synchronous transmission system. The power emission circuit of the power and information synchronous transmission system converts the external power supply into high-frequency alternating current and emits it to the receiving coil through the transmitting coil. The receiving coil converts the induced alternating current into direct current through the power receiving circuit and supplies it to the camera for operation. To ensure the stability and efficiency of power supply, the present invention designs a variety of power management algorithms. The device is also equipped with a variety of safety protection mechanisms to ensure the stable operation of the system. The system realizes real-time data interaction with users through the wireless communication module (Wi-Fi or Bluetooth, ZigBee). Users can monitor and manage the device through mobile phones, tablets or computers.

[0038] The functions of each module are further explained as follows:

[0039] System Scheduling: The intelligent switching system powers the power and information synchronous transmission system according to the monitored power status of the photovoltaic panels, the energy storage module, and the external power grid. By monitoring the power in real time, it ensures automatic switching of the system under different power conditions, guaranteeing the continuous and stable operation of the camera.

[0040] Real-time Power Display: Users can view real-time data of the photovoltaic cells, energy storage module, external power grid, etc.

[0041] Remote Control: Users can adjust the working mode through remote operations, such as switching power sources, adjusting the working status of the camera, etc.

[0042] Abnormal Alarm: When a system failure occurs or the battery power is too low, the system will send an alarm message to the user through the network to ensure timely problem handling.

[0043] The wireless non-stop power photovoltaic energy storage camera device of the present invention has the characteristics of compact structure, complete functions, and strong environmental adaptability. It can meet the monitoring requirements in the environment along high-voltage power grids and has important application value and market prospects.
