Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0051] Example 1:

[0052] The embodiment of the present invention provides a multi-scenario implementation method of a photoelectric conversion device, such as Figure 1 and Figure 2 Shown, including:

[0073] In this embodiment, Figure 2 As shown, the battery indicator usually uses a pointer, a digital tube or an LED light to display the remaining power.

[0074] The beneficial effects of the above technical solution are: by providing the photoelectric conversion device with a built-in battery, a power indicator and a charging interface, the power supply method can be flexibly selected, the power level can be monitored in real time, and the battery charging management can be automatically performed, thereby improving the device's ease of use, energy efficiency management and battery life.

[0093] In this embodiment, the horizontal axis of the frequency-amplitude graph represents the frequency, and the vertical axis represents the amplitude of the corresponding frequency, so that the distribution of the signal at each frequency can be observed intuitively.

[0094] In this embodiment, the horizontal axis of the frequency-power graph is frequency, and the vertical axis is power, which intuitively reflects the energy distribution of the signal at different frequencies.

[0095] In this embodiment, it is observed whether each feature in the sub-feature vector changes gradually over time or exhibits periodic fluctuations, so as to identify potential long-term changes or mode switching.

[0096] In this embodiment, the extreme amplitude value refers to the maximum amplitude in the frequency-amplitude diagram, representing the strongest frequency component in the signal.

[0097] In this embodiment, the main amplitude range refers to a region in the frequency-amplitude diagram where the amplitudes are significantly concentrated, reflecting the amplitude range of the main frequency components in the signal.

[0098] In this embodiment, the main frequency range refers to a frequency interval in which energy is significantly concentrated in the frequency-power graph, reflecting the frequency range in which the main energy in the signal is concentrated.

[0099] In this embodiment, the distribution uniformity value represents the degree of uniformity of the distribution of frequency domain data in terms of frequency and amplitude, and is used to measure whether the distribution of data at different frequencies is consistent.

[0100] The beneficial effects of the above technical solution are as follows: by extracting features from all working modes of the photoelectric conversion device and determining the feature vector of each working mode, a data basis can be provided for determining the current working mode of the current scene in which the photoelectric conversion device is currently located, so as to dynamically match the current working mode according to the environmental data.

[0124] Example 6:

[0125] An embodiment of the present invention provides a multi-scenario implementation method for a photoelectric conversion device, which determines the current operating mode of the current scenario of the photoelectric conversion device based on all feature vectors and an estimated environment vector, including:

[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 on the predicted 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 predicted environmental vector to determine the environmental vector of the current scene.

[0127] Based on the environment vector and the feature vector of each working mode, the matching value between each working mode and the environment vector of the current scene is calculated;

[0131] In this embodiment, the number of eigenvalues ​​contained in the working mode feature vector is first compared with the number of key environmental variables. If the number of key environmental variables is greater than the number of eigenvalues ​​in the feature vector, it means that the dimension of the environmental data is high and the expected environmental vector needs to be reduced in dimension. If the number of key environmental variables is less than the number of eigenvalues, the environmental vector needs to be increased in dimension through interpolation.

[0132] In this embodiment, when the dimension of the environmental data is too high, the dimension reduction method may be principal component analysis (PCA), linear discriminant analysis (LDA), etc.

[0133] In this embodiment, when the dimension of the environmental data is low, the dimension is increased by interpolation to make the environmental data match the feature vector.

[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 panel of a photoelectric conversion device into electrical energy;

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

[0149] The battery indicator displays the battery level of the photoelectric 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 supply or to use the external charging port for power supply according to the current environment or scene. For example, if the current scene environmental conditions are suitable for built-in battery power supply, the device may give priority to using the battery; when the battery power is low, it may switch to the charging port for power supply.

[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 battery indicator that displays the battery level. The user can use it to view the current battery level and voltage of the device in real time, understand the remaining available battery power and voltage, and conveniently determine whether the device needs to be charged or replaced.

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.
