[0047] The "first", "second" in the present application do not represent the specific number and order, but only for the name of the distinction.
[0048] As Figure 1 An embodiment of the present application provides a self-powered remote control method based on micro-light energy collection, comprising the following steps:
[0049] S1, providing a micro-light energy collection unit, collecting light source energy in the environment through the micro-light energy collection unit and converting the light source energy into electric energy.
[0050] The micro-light energy collection unit is composed of a photodiode or a photovoltaic cell array, which can efficiently collect weak light energy (such as indoor light, outdoor scattered sunlight, etc.) and convert the light energy into electric current.
[0051] S2, providing an energy conversion unit, converting the electric energy into stable direct current through the energy conversion unit.
[0052] The energy conversion unit is composed of a high-efficiency energy conversion chip, which converts the electric energy into stable direct current and transmits the direct current to the energy storage unit.
[0053] S3, providing an energy storage unit, storing the direct current through the energy storage unit.
[0054] The energy storage unit adopts a large-capacity capacitor such as a super capacitor, a lithium ion capacitor, etc., which has a higher energy storage density and a longer service life, and can store energy for a long time at a lower voltage.
[0055] S4, providing a remote control unit, providing power for the remote control unit through the electric energy stored in the energy storage unit and realizing control of the target device.
[0056] The remote control unit can communicate with the target device through a wireless signal (such as infrared, radio frequency, Bluetooth, etc.) transmission module, and use the electrical energy stored in the energy storage unit to send signals and control the target device, that is, use the electrical power provided by the energy storage unit to control the functions of the target device, such as switching, adjusting, etc.
[0057] The self-powered remote control method based on micro-light energy collection collects light source energy in the environment through a micro-light energy collection unit and converts the light source energy into electrical energy, and converts it into direct current through an energy conversion unit, and stores electrical energy through an energy storage unit. It can work continuously in a low brightness environment, and can realize self-power supply relying on micro-light, providing stable power supply for low-power devices such as remote control devices, solving the problem that existing micro-light power generation technology cannot fully solve the energy collection and storage of low-power devices in indoor or weak light environments, and avoiding the transportation, cost and environmental pollution problems brought by the use of traditional batteries. Compared with the prior art, the self-powered remote control method based on micro-light energy collection has lower use cost, longer use cycle and higher environmental friendliness.
[0058] As a preferred technical solution, as shown in Figure 2 The self-powered remote control method based on micro-light energy collection further includes the following steps:
[0059] S5, obtain the energy storage wake-up threshold and the remaining energy of the energy storage unit, and construct a sleep duration decay term according to the energy storage wake-up threshold and the remaining energy.
[0060] Specifically, the greater the difference between the remaining energy and the energy storage wake-up threshold, the smaller the value of the sleep duration decay term. Preferably, the sleep duration decay term is an exponential decay term that adjusts the basic sleep duration according to the energy storage state of the energy storage unit. The closer the remaining energy is to the energy storage wake-up threshold, the shorter the sleep time, ensuring that the system responds quickly when the remaining energy is sufficient, and prolonging the sleep time when the remaining energy is low, prolonging the service life of the system.
[0061] More specifically, Where T0 represents the basic sleep duration, e represents the natural constant, E store represents the remaining energy, E threshold represents the energy storage wake-up threshold. For the energy storage wake-up threshold E threshold , it can be 1.5 times the energy consumption of a single complete working cycle of the system, and is optimized in combination with Monte Carlo simulation. For the energy consumption of a single complete working cycle of the system, it can be the energy consumption of a certain time node selected, and is preferably the average energy consumption of N time nodes.
[0062] Specifically, a sleep duration exponential decay model is introduced herein to replace the traditional linear threshold judgment, thereby avoiding the problem of frequent wake-up of the energy storage unit in the energy critical region.
[0063] S6, obtaining an energy change trend of the light source energy and a sleep duration correction factor, constructing a sleep duration correction term according to the energy change trend and the sleep duration correction factor, and increasing a value of the sleep duration correction term when the light source energy increases, and decreasing the value of the sleep duration correction term when the light source energy decreases.
[0064] Specifically, wherein τ represents the sleep duration correction factor, and sgn() represents a sign function.
[0065] Based on the energy change trend , the sleep offset is adjusted, i.e., the size of the sleep duration correction term is adjusted. When the energy is in an upward trend , the sleep time is prolonged, and when the energy is in a downward trend , the sleep time is shortened. In this way, in combination with the dynamic characteristics of energy harvesting, the limitations of the traditional static sleep strategy can be broken through.
[0066] For the energy change trend , a sliding time window (such as 10 seconds) is used to calculate the energy change rate, thereby avoiding the interference of instantaneous fluctuations.
[0067] Preferably, as Figure 3 shown, in step S6, the specific method for obtaining the sleep duration correction factor includes the following steps:
[0068] S61, obtaining an energy distribution complexity in a preset time period. The energy distribution complexity wherein N represents the number of time nodes in the preset time period, p i represents an energy distribution probability of the i-th time node, and satisfies The time nodes in the preset time period can be set by a technician, for example, the preset time period is set to one day, the number of time nodes is set to 24, and the energy distribution probability of a certain time node is the ratio of the total energy consumption in a preset time width before and after the time node to the total energy consumption in one day.
[0069] It can be understood that when tends to 0, the energy distribution of the N time nodes in the preset time period is highly concentrated, and a certain time node occupies most of the energy. When H E → lnN, the energy distribution of the N time nodes in the preset time period is uniform.
[0070] S62, obtaining the sleep duration correction factor according to the energy distribution complexity.
[0071] Preferably, τ=k·H E wherein k represents the system sensitivity, which can be set by the technician according to experience. The energy distribution complexity As a dynamic adjustment parameter of the dormancy duration correction factor, it can be based on the energy entropy The dynamic adjustment of the dormancy duration realizes more refined dormancy scheduling control. In the high entropy state, the dormancy duration correction factor is amplified, the dormancy time is prolonged to reduce the energy consumption of frequent wake-up, and in the low entropy state, the dormancy duration correction factor is reduced, and the system response speed is preferentially ensured.
[0072] S7, constructing a dormancy duration dynamic adjustment mechanism of the remote control unit according to the dormancy duration decay term and the dormancy duration correction term. Specifically, the dormancy duration dynamic adjustment mechanism can be understood as T sleep represents the total dormancy duration.
[0073] By constructing the dormancy duration dynamic adjustment mechanism, the self-powered remote control method of the present application reduces the wake-up delay by more than 30% compared with the traditional fixed dormancy strategy, and the system static power consumption can be controlled within 3μA under 200lx illumination.

Each photodiode can convert weak light energy into a photocurrent and be connected to the energy conversion unit through a conductive circuit.
[0076] Preferably, the micro-light energy collection unit can work under weak light conditions and be arranged on the front, back, side or front and back of the device or multiple sides or other multiple sides to improve the energy collection efficiency.
[0077] The energy conversion unit is used to convert the electrical energy into stable direct current. The energy conversion unit uses high-efficiency energy conversion chips to convert the energy collected by the micro-energy collection unit into direct current. This conversion unit has high conversion efficiency, ensuring that it can still output a stable current under weak light sources. The current is transmitted to the energy storage unit for subsequent use.
[0078] The energy storage unit is used for storing the direct current, which uses supercapacitors, lithium ion capacitors and the like to store energy. Compared with traditional batteries, supercapacitors and lithium ion capacitors have longer service life and higher energy density. Through the supercapacitor, the system can store energy for a long time at low voltage, avoiding the charging cycle and pollution problems of traditional lithium batteries.

Preferably, the self-powered remote control device based on micro-light energy collection further comprises a wireless signal transmission module for sending remote control signals to realize functional control of the target device.
[0080] The remote control unit uses wireless remote control technology (such as radio frequency, infrared, Bluetooth, etc.), which can receive and send remote control signals and send signals to the target device through the wireless signal transmission module. The device relies on stored electrical energy and does not require an external power source, thus having a low maintenance cost.
[0081] The self-powered remote control device based on micro-light energy collection collects light source energy in the environment through the micro-light energy collection unit and converts the light source energy into electrical energy, and converts it into direct current through the energy conversion unit, and stores electrical energy through the energy storage unit, which can work continuously in low brightness environment, and can realize self-power supply relying on micro-light, providing stable power supply for low-power devices such as remote control devices, solving the problem that the existing micro-light power generation technology cannot fully solve the energy collection and storage of low-power devices in indoor or low-light environments, and avoiding the transportation, cost and environmental pollution problems caused by using traditional batteries.

[0086] The hibernation duration correction term construction unit is configured to obtain the energy change trend of the light source energy and the hibernation duration correction factor, and construct the hibernation duration correction term according to the energy change trend and the hibernation duration correction factor, so as to increase the value of the hibernation duration correction term when the light source energy increases, and decrease the value of the hibernation duration correction term when the light source energy decreases.
[0087] The hibernation duration dynamic adjustment mechanism construction unit is configured to construct the hibernation duration dynamic adjustment mechanism of the remote control unit according to the hibernation duration decay term and the hibernation duration correction term.

[0091] Specifically, wherein T0 represents the basic hibernation duration, e represents the natural constant, E store represents the residual energy, E threshold represents the energy storage wake-up threshold. For the energy storage wake-up threshold E threshold , it can be 1.5 times of the energy consumption of a complete system cycle (such as the energy consumption of a selected time node, preferably the average energy consumption of N time nodes), and is combined with Monte Carlo simulation optimization. Here, by introducing the hibernation duration exponential decay model, it can replace the traditional linear threshold judgment, and avoid the problem of frequent wake-up of the energy storage unit in the energy critical region.
[0092] wherein τ represents the hibernation duration correction factor, and sgn() represents the sign function. Based on the sign of the energy change trend , the hibernation offset is adjusted, that is, the size of the hibernation duration correction term is adjusted. When the energy is in an upward trend , the hibernation time is lengthened, and when the energy is in a downward trend , the hibernation time is shortened. In this way, combined with the dynamic characteristics of energy harvesting, the limitations of traditional static hibernation strategies can be broken through. For the energy change trend The energy change rate is calculated by using a sliding time window (e.g., 10 seconds) to avoid interference of instantaneous fluctuations.

It can be understood that when tends to 0, the energy distribution of the N time nodes in the preset time period is highly concentrated, and a certain time node occupies most of the energy. When H E → lnN, the energy distribution of the N time nodes in the preset time period is uniform.
[0094] The sleep duration correction factor τ = k · H E wherein k represents the system sensitivity, which can be set by the technician according to experience. The energy distribution complexity is used as a dynamic adjustment parameter of the sleep duration correction factor, which can dynamically adjust the sleep duration based on the energy entropy to realize more refined sleep scheduling control. In the high-entropy state, the sleep duration correction factor is amplified to prolong the sleep time to reduce the energy consumption of frequent wake-up. In the low-entropy state, the sleep duration correction factor is reduced to prioritize the system response speed.
[0095] The sleep duration dynamic adjustment mechanism can be understood as T sleep represents the total sleep duration.
