[0047] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.
[0048] like Figure 1 As shown, an embodiment of the present invention provides a self-powered remote control method based on low-light energy harvesting, comprising the following steps:
[0049] S1, providing a low-light energy collection unit, collecting light source energy in the environment through the low-light energy collection unit and converting the light source energy into electrical energy.
[0050] The low-light energy collection unit is composed of a photodiode or a photocell array, which can efficiently collect low-light energy under low-light sources (such as indoor lights, scattered sunlight outside the window, etc.) and convert the light energy into electric current.
[0051] S2, providing an energy conversion unit, and converting the electrical 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 electrical energy into stable direct current and transmits the direct current to the energy storage unit.
[0053] S3, providing an energy storage unit, and storing the direct current through the energy storage unit.
[0054] The energy storage unit uses a large-capacity capacitor such as a supercapacitor, 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, using the electric energy stored in the energy storage unit to provide power to the remote control unit and realize 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 electric energy stored in the energy storage unit to send signals and control the target device, that is, use the power provided by the energy storage unit to control the function 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 then stores the electrical energy through an energy storage unit. It can continue to work in a low-brightness environment and can achieve self-power by relying on micro-light, providing a stable power supply for low-power devices such as remote control devices, solving the problem that existing micro-light power generation technology fails to fully solve the problem of 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 the use of traditional batteries. Compared with the prior art, the self-powered remote control method based on micro-light energy collection described in the present invention has lower use costs, longer use cycles and higher environmental friendliness.
[0058] As a preferred technical solution, Figure 2 As shown, the self-powered remote control method based on low-light energy harvesting also includes the following steps:
[0059] S5, obtaining an energy storage wake-up threshold and the remaining energy of the energy storage unit, and constructing a sleep duration attenuation 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, which 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 is, ensuring that the system responds quickly when the remaining energy is sufficient, and when the remaining energy is low, the sleep time is extended to extend the service life of the system.
[0061] More specifically, Among them, T 0 represents the basic sleep duration, e represents the natural constant, E store Represents the remaining energy, E threshold Indicates the energy storage wake-up threshold. threshold , which can be 1.5 times the energy consumption of a single complete working cycle of the system, and combined with Monte Carlo simulation optimization. The energy consumption of a single complete working cycle of the system can be the energy consumption of a selected time node, preferably the average energy consumption of N time nodes.
[0062] Specifically, an exponential decay model of sleep duration is introduced here, which can replace the traditional linear threshold judgment and avoid the problem of frequent awakening of the energy storage unit in the energy critical area.
[0063] S6, obtaining the energy change trend of the light source energy and the sleep duration correction factor, and constructing a sleep duration correction item according to the energy change trend and the sleep duration correction factor, so as to increase the value of the sleep duration correction item when the light source energy increases, and reduce the value of the sleep duration correction item when the light source energy decreases.
[0064] Specifically, Wherein, τ represents the sleep duration correction factor, and sgn() represents the sign function.
[0065] Based on energy trend The sign of the sleep offset is adjusted, that is, the size of the sleep duration correction term is adjusted. When the energy is on an upward trend Extend the dormancy time, downward trend In this way, combined with the dynamic characteristics of energy harvesting, the limitations of traditional static sleep strategies can be overcome.
[0066] Regarding the energy change trend A sliding time window (such as 10 seconds) is used to calculate the energy change rate to avoid interference from instantaneous fluctuations.
[0067] Preferably, if Figure 3 As shown, in step S6, the specific method for obtaining the sleep duration correction factor includes the following steps:
[0068] S61, obtaining the energy distribution complexity within a preset time period. Energy distribution complexity Where N represents the number of time nodes in the preset time period, p i represents the energy distribution probability of the i-th time node, and is normalized to satisfy The time nodes within the preset time period can be set by technical personnel. For example, the preset time period is set to one day, and the number of time nodes is set to 24. The energy distribution probability of a certain time node is the ratio of the total energy consumption of the preset time width before and after the time node to the total energy consumption of one day.
[0069] Understandably, when When it approaches 0, the energy distribution of the N time nodes within the preset time period is highly concentrated, and a certain time node occupies most of the energy. E →lnN, the energy distribution of the N time nodes within the preset time period is uniform.
[0070] S62: Obtain the sleep duration correction factor according to the energy distribution complexity.
[0071] Preferably, τ = k·H E , where k represents the system sensitivity and can be set by technicians based on experience. As a dynamic adjustment parameter of the sleep duration correction factor, it can be based on energy entropy Dynamically adjust the sleep duration to achieve more refined sleep scheduling control. In the high entropy state, the sleep duration correction factor is amplified to extend the sleep time to reduce the energy consumption of frequent wake-ups. In the low entropy state, the sleep duration correction factor is reduced to prioritize system response speed.
[0072] S7: construct a sleep duration dynamic adjustment mechanism for the remote control unit according to the sleep duration attenuation term and the sleep duration correction term. Specifically, the sleep duration dynamic adjustment mechanism can be understood as: T sleep Indicates the total sleep time.
[0073] By constructing the sleep duration dynamic adjustment mechanism, the self-powered remote control method of the present invention reduces the wake-up delay by more than 30% compared with the traditional fixed sleep strategy, and the static power consumption of the system can be controlled within 3μA under an illumination of 200lx.
