[0002] Photoelectric conversion equipment is widely used in solar photovoltaic power generation, photoelectric sensors, photoelectric detectors, and optical communications. However, photoelectric conversion equipment can usually only operate in fixed scenarios or specific conditions, and lacks the ability to adapt to different environments. When environmental conditions change, the equipment needs to be manually adjusted or reconfigured, making it difficult to achieve intelligent and automated operation. The response to the environment is not sensitive enough, and its working mode cannot be optimized according to real-time environmental conditions, resulting in reduced energy efficiency and waste of resources. In addition, traditional equipment cannot accurately identify the characteristics of different scenarios.

[0126] Compare the number of eigenvalues ​​in the feature vector of the working mode and the number of key environmental variables. If the number of key environmental variables is greater than the number of eigenvalues ​​in the feature vector, perform dimensionality reduction processing on the estimated environmental vector to determine the environmental vector of the current scene; if the number of key environmental variables is less than the number of eigenvalues ​​in the feature vector, perform interpolation and dimensionality increase on the estimated environmental vector to determine the environmental vector of the current scene;

[0140] After the photoelectric conversion device switches to the current working mode, the working parameters of the current working mode of the photoelectric conversion device are adjusted based on the matching value between the characteristic vector corresponding to the current working mode and the environment vector.

[0141] In this embodiment, after switching to the current working mode, the photoelectric conversion device will dynamically adjust the working parameters of the device according to the matching value between the characteristic vector of the current working mode and the current environment vector. The matching value reflects the adaptability of the device to operate in the current environment. The larger the matching value, the smaller the parameter adjustment of the device. When the matching value is small, the device may need a larger adjustment to better adapt to the environment.

[0143] Embodiment 8:

[0144] An embodiment of the present invention provides a multi-scenario implementation method of a photoelectric conversion device, wherein the photoelectric conversion device selects a built-in battery or a charging interface for power supply based on the current scenario;

[0145] The built-in battery can be charged by connecting to the charging port;

[0146] The built-in battery includes a photovoltaic cell assembly that can be charged by converting light energy absorbed by a photovoltaic cell panel of a photoelectric conversion device into electrical energy;

[0147] When the voltage of the built-in battery is lower than the first set threshold, the built-in battery is charged, and when the voltage of the built-in battery is higher than the second set threshold, the charging is stopped;

[0148] When the power consumption rate of the photoelectric conversion device is greater than the preset power consumption rate, the built-in battery is charged;

[0149] The battery indicator displays the battery level of the optoelectronic device and the voltage of the built-in battery.

[0150] In this embodiment, the device will automatically choose to use the built-in battery for power or to power through the external charging port according to the current environment or scene. For example, if the current scene environmental conditions are suitable for built-in battery power, the device may give priority to using the battery; when the battery power is low, it may switch to the charging port for power.

[0151] In this embodiment, the first set threshold represents the lower limit of the built-in battery voltage. When the voltage is lower than this threshold, the device starts charging.

[0152] In this embodiment, the second set threshold represents the upper limit of the built-in battery voltage. When the voltage exceeds this threshold, the device stops charging to prevent overcharging.

[0153] In this embodiment, the preset power consumption rate represents the upper limit of the power consumption rate of the photoelectric conversion device. When the power consumption rate is higher than this threshold, the device consumes electricity faster and starts charging.

[0154] In this embodiment, the device is provided with a power indicator for displaying the power level, through which the user can view the current battery power value and the current battery voltage value of the device in real time, understand the remaining available power and voltage of the battery, and conveniently determine whether the device needs to be charged or replaced.

[0155] The beneficial effects of the above technical solution are: automatic switching of power supply modes and intelligent control of battery charging through scene perception, which achieves energy efficiency optimization and improved power safety. The power indicator displays power information in real time for easy monitoring, which helps to extend the life of the equipment and improve its ease of use.
