[0019] In the figure: low - level light solar panel 1, low - level light collection circuit 2, main chip 3, energy storage unit 4, communication module 5, ink screen 6, USB charging port 7. Detailed Embodiments

[0020] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0022] As Figure 1 shown, an intelligent electronic tag powered by low - level light provided by an embodiment of the present utility model includes:

[0023] A low - level light solar panel 1, which collects ambient light or human body heat energy through photoelectric conversion technology and converts it into electric energy;

[0024] A low - level light collection circuit 2, connected to the low - level light solar panel 1, for receiving the electric energy converted by the low - level light solar panel 1;

[0025] A main chip 3, used for processing data, controlling instructions and managing electric energy;

[0026] An energy storage unit 4, connected to the low - level light collection circuit 2 and the main chip 3, for receiving and storing the converted electric energy;

[0027] A display unit, connected to the main chip 3, for receiving and displaying instruction content;

[0028] A communication module 5, connected to the main chip 3, for wireless communication connection with a mobile phone APP or a relay device.

[0029] In the embodiment of the present utility model, since the intelligent electronic tag powered by low - level light no longer needs to replace the battery, the shell can be made of a closed waterproof treatment.

[0030] Low - light energy harvesting can receive ambient light or human body heat energy and convert it into electrical energy to provide a persistent power supply for the electronic tag. The collection of low - light energy mainly relies on photovoltaic conversion technology, that is, converting light energy into electrical energy. This conversion process is mainly achieved through photovoltaic cells or so - called solar cells. A photovoltaic cell is a semiconductor device that uses the photovoltaic effect to directly convert light energy into electrical energy. Its working principle is: when light irradiates the surface of the photovoltaic cell, the semiconductor material inside the photovoltaic cell absorbs the light energy, causing electrons to jump from the valence band to the conduction band, forming electron - hole pairs. When the electron - hole pairs are separated under the action of the internal electric field, electrons flow to the n - type semiconductor and holes flow to the p - type semiconductor, thus forming an electric current in the external circuit. A low - light cell is a special photovoltaic cell that can work under weak light sources and can generate current even under indoor lighting conditions. Low - light cells usually use silicon - based or organic semiconductor materials. By optimizing the material and device structure, the response performance to weak light sources is improved, thus realizing the effective collection and conversion of low - light energy. In an electronic tag powered by low - light, the low - light solar panel 1 can be integrated on the shell of the electronic tag to convert ambient light or human body heat energy (infrared light) into electrical energy to provide a persistent power supply for the electronic tag.

[0031] As Figure 1 shown, as a preferred embodiment of the present utility model, the energy storage unit 4 includes a lithium battery, a supercapacitor, a lithium capacitor, a tantalum capacitor, etc.

[0032] In the embodiment of the present utility model, the energy provided by the low - light solar is relatively limited, and it is only about 10 μW basically under indoor light conditions. This energy must be stored through the energy storage unit 4.

[0033] As Figure 1 shown, as a preferred embodiment of the present utility model, the display unit uses an e - ink screen 6.

[0034] In the embodiment of the present utility model, in order to save power to the greatest extent, the electronic tag uses e - ink screen 6 (E - Ink) technology. The biggest feature of the e - ink screen 6 technology is that it can be powered off when there is no updated content, which can save energy consumption to the greatest extent.

[0035] As Figure 1 shown, as a preferred embodiment of the present utility model, the communication module 5 is Bluetooth, ultra - wideband wireless communication technology (UWB), 433 MHz radio frequency (RF) communication, or StarFlash. Users can operate through one of the communication methods, improving the operation convenience and deployment convenience.

[0036] In the embodiment of the present utility model, the working principle of the intelligent electronic tag powered by low-level light mainly relies on the built-in Bluetooth module and voice recognition module. The following is its working process: The user issues an instruction to the electronic tag to modify its content, which can be directly connected (via Bluetooth or XingFlash) to the mobile phone APP or forward data through a relay (UWB or RF communication). When the electronic tag receives the information, it will display the corresponding content on the corresponding ink screen 6.

[0037] To save power to the maximum extent and achieve low power consumption, the communication of the entire system adopts intermittent communication. When it is not working usually, the power supply of all communication modules 5 is set to be turned off for a period of time. Only within the interval time, the communication module 5 is turned on to quickly communicate with the relay or APP to check if there is an update. If an update is required, continuous communication is carried out until the data update is completed, and then the communication is immediately disconnected and the power supply of the communication module is stopped, and the system enters the low power consumption mode again.

[0038] As Figure 1 shown, as a preferred embodiment of the present utility model, the main chip 3 has a relatively low power consumption when not in communication, lower than 1 μA.

[0039] As Figure 1 shown, as a preferred embodiment of the present utility model, it further includes a USB charging port 7 to provide an additional charging interface. When the solar energy storage is insufficient, it can be replenished through a USB charger.

[0040] The above is only the preferred implementation manner of the present utility model. It should be noted that for those skilled in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
