Description

Technical Field

[0001] The present invention belongs to the technical field of computer applications, and in particular relates to a solar charging and power supply method, a storage medium, a solar charging and power supply controller, and a mobile device. Background Art

[0002] Mobile devices used for indoor and outdoor activities are usually powered by batteries. Since mobile devices used for indoor and outdoor activities consume a lot of power, the battery life is short. Increasing the battery capacity will increase the volume and weight of the battery. Therefore, the frequency of replacing or charging the battery is high. For mobile devices that need to be used continuously for a long time, frequent battery replacement or battery charging will reduce the efficiency of the mobile device. In addition, mobile devices powered by pure batteries face the problem of battery exhaustion, which will also reduce the efficiency of the mobile device.

[0003] The following example uses the scenario of indoor and outdoor positioning of mobile devices for indoor and outdoor movement. Indoor and outdoor positioning technologies usually include GPS positioning, Bluetooth positioning, WiFi positioning, and LoRa positioning. At present, high-precision locators on the market mostly use UWB positioning technology. UWB is a wireless communication technology that does not require a carrier. It is a positioning system usually composed of a fixed end and a mobile end. UWB beacons are usually used for indoor or outdoor positioning, as well as for personnel positioning and material positioning. Compared with other positioning technologies, it has the advantages of high positioning accuracy (10cm) and high positioning frequency. However, compared with Bluetooth positioning and other positioning methods, UWB power consumption is much greater. Specifically, Bluetooth beacons have a high power consumption of 100W and a low power consumption of 100W. Using two 1.5V dry batteries, it can be used for several years or longer, but the overall power consumption of UWB beacons (UWB locators) is relatively large. At the same positioning frequency as Bluetooth beacons, using two 1.5V dry batteries, UWB beacons can only last for about a month. Increasing the capacity of the battery in the UWB beacon will cause the size and weight of the UWB beacon to become larger. In addition, the pure battery power supply solution of UWB beacons on the market faces the problem of power exhaustion, and the battery needs to be replaced manually or charged manually, which causes the problem of power exhaustion. Therefore, it is necessary to solve the problems of high power consumption and short battery life of UWB beacons.

[0074] Reference Figure 2 The solar charging and power supply method of this embodiment includes the following steps:

[0075] S210, determining whether the remaining power of the rechargeable battery is less than the maximum power of the rechargeable battery:

[0076] If yes, then execute step S220; if no, then close the charging channel of the solar panel to the rechargeable battery;

[0077] S220, determining whether the output voltage of the solar panel is less than a first preset threshold:

[0095] In this embodiment, when the mobile device is in a stationary state, the mobile device is controlled to sleep, thereby reducing the power consumption of the mobile device, or even consuming almost no power. Therefore, the solar energy charging time for the battery will be shorter and the charging speed will be faster.

[0096] Embodiment 3

[0097] In order to solve the above technical problems existing in the prior art, an embodiment of the present invention provides a solar charging and power supply method applied to a UWB beacon, wherein the UWB beacon includes a UWB beacon circuit that needs to be powered and a 3.7V lithium battery that needs to be charged.

[0098] As for the power supply of the UWB beacon circuit, there are three power supply channels, namely solar power supply, lithium battery power supply and external USB power supply. Each power supply channel can independently supply power to the UWB beacon circuit or simultaneously supply power to the UWB beacon.

[0099] For the 3.7V lithium battery charging power supply, it includes a solar power charging channel and an external USB power charging channel. The two channels can charge the lithium battery simultaneously or independently.

[0100] Among them, the energy conversion relationship between solar power supply, external USB power supply, 3.7V lithium battery and UWB beacon circuit is as follows: Figure 3 As shown in the figure, the arrow direction is the energy transmission direction. Figure 3 The energy conversion relationship diagram is based on the power energy transmission and conversion relationship between solar energy, external input power, lithium battery and UWB beacon. In order to maximize the comprehensive utilization efficiency of lithium battery power and solar power, the intelligent detection and conversion of power is realized to extend the battery life of UWB beacon. The charging and power supply channels can be intelligently controlled by intelligently detecting the intensity of sunlight, the power level of lithium battery and the presence or absence of external power supply. Among them, the control chip used for intelligent control can be the controller STM32L041G6U6STR.

[0101] The intensity of sunlight can be determined by the output voltage of the solar panel detected by the solar voltage detection circuit. For example, taking a 6.8V solar panel as an example, when the output voltage of the solar panel is 5.8-6.8V, it is considered that the sunlight is sufficient. When the output voltage of the solar panel is 4.5V-5.8V, it is considered that the sunlight is weak. When the output voltage of the solar panel is less than 4.5V, it is considered that there is no sunlight. According to the energy conversion relationship of the UWB beacon and the principle of efficient use of electric energy, in order to improve the battery life of the UWB beacon, the solar intelligent charging power supply can be subdivided into the following situations. The specific process of its implementation is as follows Figure 4 As shown:

[0102] (1) No external power supply

[0103] ① When it is detected that there is sufficient sunlight and the lithium battery is fully charged, the lithium battery cannot be charged any further, the solar power supply channel switch S1 is turned on, the charging channel switch S2 is turned off, the solar energy stops charging the polymer lithium battery, and continues to supply power to the UWB mainboard circuit;

[0104] ② When it is detected that there is sufficient sunlight and the lithium battery is not fully charged, the charging channel power switch S2 and the power supply channel switch S1 are both turned on, and the solar energy charges the lithium battery;

[0105] ③ When weak sunlight is detected, considering the voltage stability problem, solar energy does not supply power to the UWB mainboard, but uses the lithium battery charging channel to supply power to the UWB control circuit; the charging channel switch S2 is turned on, the power supply channel switch S1 is turned off, the solar energy only charges the lithium battery slowly, and the UWB mainboard circuit is powered by the lithium battery;

[0106] ④When no sunlight is detected, S1 and S2 are closed, solar charging and power supply are stopped, and the lithium battery directly powers the UWB mainboard circuit;

[0107] (2) When there is an external power supply

[0108] ① When the lithium battery is detected to be fully charged, it cannot continue to charge the lithium battery, the external power supply stops charging the lithium battery, and only supplies power to the UWB mainboard circuit;

[0109] ② When it is detected that the lithium battery is not fully charged, the external power supply directly charges the lithium battery and supplies power to the UWB beacon. If the sunlight meets the charging and power supply requirements, the solar energy and external power supply can charge the lithium battery and supply power to the UWB mainboard circuit at the same time;

[0110] Through the above-mentioned logical judgment and power supply situation analysis, while maintaining the power supply of the UWB beacon, the solar power supply and charging channels are intelligently controlled. Once sunlight shines on the UWB beacon and the charging conditions are met, the solar energy will charge the lithium battery to achieve energy storage and reuse, thereby extending the battery life of the lithium battery.

[0111] Since the UWB beacon is not always in motion, the gyroscope sensor LIS3DH can be used to detect the motion state of the UWB beacon, and the gyroscope sensor data can be read through the main controller STM32L041G6U6STR chip via the IIC protocol bus to control the low power consumption of the UWB beacon; Figure 5This is the motion state detection and low power control flow chart of UWB beacon. The function of gyroscope sensor is to detect the motion state of beacon, so as to put UWB beacon into sleep mode and trigger the awakening of UWB beacon positioning. When the beacon is stationary, the positioning position will not change. When the UWB beacon is stationary, if the UWB communication positioning function is still turned on, the change of positioning position will be meaningless, and the UWB beacon will continue to consume power. Therefore, in order to further control the UWB beacon to reduce power consumption, the gyroscope is used as motion detection sensor. When the gyroscope sensor detects that the UWB beacon is stationary, the main controller controls the UWB beacon to enter sleep mode, and the main controller STM The 32L041G6U6STR automatically enters a low-power state and sets the gyroscope sensor to a motion trigger state. Once the gyroscope sensor detects the movement of the UWB beacon, the UWB positioning chip and the STM32L041G6U6STR main control chip are awakened and the UWB communication positioning function is restarted, thereby further reducing the power consumption of UWB. When the UWB beacon is stationary, since the UWB beacon and the main controller are in a low-power mode, almost no power is consumed. Therefore, when solar energy is used for charging and power supply at the same time, the required power supply voltage is reduced and the charging voltage is increased, making the solar energy charging time for the lithium battery shorter and the charging speed faster.

[0112] This embodiment combines the intelligent control of charging and power supply determined by the intensity of sunlight with the intelligent detection of the motion status of the UWB beacon, which not only greatly reduces the power consumption of UWB, but also improves the efficiency of solar energy use while realizing intelligent repeated charging and power supply by solar energy, thereby increasing the battery life of the UWB lithium battery and reducing the number of manual charging times.

[0113] Compared with most UWB beacons on the market that are powered by lithium batteries or dry batteries, this embodiment mainly reduces the power consumption of UWB beacons through solar energy and gyroscope sensors to achieve intelligent charging of lithium batteries by solar energy, realize charging automation, and improve the battery life of UWB beacons, without the need to manually charge UWB beacons frequently.

[0120] Embodiment 6

[0121] In order to solve the above technical problems existing in the prior art, an embodiment of the present invention further provides a mobile device.

[0122] See also Figure 6 , the mobile device provided in this embodiment includes:

[0123] Solar panels;

[0124] A solar output voltage detection circuit, which is connected to the solar panel and is used to detect the magnitude of the solar panel output voltage;

[0125] Rechargeable batteries;

[0126] A rechargeable battery power detection circuit, connected to the rechargeable battery, for detecting the remaining power of the rechargeable battery;

[0127] The solar charging and power supply controller according to the fifth embodiment is connected to the solar output voltage detection circuit and the rechargeable battery power detection circuit;

[0128] A power supply channel switch, which is arranged in the circuit connection between the solar panel and other modules in the mobile device except the rechargeable battery, and whose control end is connected to the first output end of the solar charging and power supply controller;

[0129] A charging channel switch, which is arranged in the circuit connection between the solar panel and the rechargeable battery, and whose control end is connected to the second output end of the solar charging and power supply controller;

[0130] A solar output voltage stabilizing and filtering circuit, which is arranged between the solar output voltage detection circuit and the power supply channel switch, and between the solar output voltage detection circuit and the charging channel switch, and is used for filtering and stabilizing the output voltage of the solar panel;

[0131] The voltage conversion circuit is connected to the power supply channel switch and is used to convert the output voltage of the solar panel after filtering and voltage stabilization, so as to transmit the converted voltage to other modules in the mobile device except the rechargeable battery.

[0132] In particular, the solar output voltage detection circuit, the rechargeable battery, the solar charging and power supply controller, the solar output voltage stabilizing and filtering circuit, the power supply channel switch, the voltage conversion circuit, and the charging channel switch are arranged inside a fully enclosed housing, and the fully enclosed housing is composed of a plurality of the solar panels.

[0133] In practical applications, the mobile device of this embodiment can be a UWB beacon, specifically a PCB circuit mainboard of the UWB beacon, wherein the PCB circuit mainboard includes a solar voltage detection circuit, a solar pre-voltage stabilization filter circuit, a power supply channel and a charging channel switch selection circuit, a main controller low-power chip STM32L041G6U6STR, a UWB communication circuit DW1000, and a lithium battery charging management circuit BQ24073RGTER. The rechargeable battery power detection circuit is arranged in the main controller low-power chip STM32L041G6U6STR, and its specific connection circuit composition is as follows: Figure 7 As shown, the solar power supply channel and the charging channel both use the controllable power switch chip AP2111, and the enable pin of the chip pin is independently controlled by the enable signal of the main controller STM32L041G6U6STR, so as to facilitate the control of the opening and closing of the solar power supply channel and the charging channel. By controlling the power switches S1 and S2, the power supply and charging efficiency can be maximized, and the endurance of the UWB beacon can be improved.

[0134] See also Figure 7When sunlight shines on the surface of the solar panel of the UWB beacon, the voltage output by the solar panel is detected by the solar voltage detection circuit to determine the strength of the sunlight. The main controller low-power chip STM32L041G6U6STR controls the opening and closing of the solar power supply channel switch S1 and the solar charging channel switch S2 according to the strength of the sunlight. When the solar power supply channel switch S1 or the solar charging channel switch S2 is turned on, due to the unstable voltage output by the solar panel, a stable voltage is obtained through the solar pre-stabilization filter circuit, and then the charging channel and the power supply channel are intelligently controlled to realize solar power supply to the UWB beacon and solar power charging to the lithium battery of the UWB beacon. At the same time, the PCB circuit main board also adopts a USB interface design, which can use a 5V external power supply to power the UWB beacon and charge the lithium battery of the UWB beacon; among them, the PC The B circuit main board is also equipped with an LDO voltage regulator circuit and a lithium battery charging management circuit chip BQ24073RGTER. The LDO voltage regulator circuit is set because the power supply voltage required by the main controller low-power chip STM32L041G6U6STR is 3.3V. The voltage of the solar voltage regulator (5V-9V) and the voltage of the 3.7V lithium battery are too large to directly power the main controller low-power chip STM32L041G6U6STR. The LDO voltage regulator circuit is required to reduce the voltage to 3.3V; the lithium battery charging management circuit chip is BQ24073RGTER because when the charging power supply charges the lithium battery, the charging current needs to be controlled according to the remaining power of the lithium battery. For example, when the remaining power of the lithium battery is less, the charging current is larger. As the remaining power of the lithium battery increases, the charging current is slowly reduced until the lithium battery is fully charged. The main controller low-power chip STM32L041G6U6STR is also connected to the gyroscope sensor circuit LIS3DH, so that when the gyroscope sensor detects that the UWB beacon is stationary, the main controller controls the UWB beacon to enter sleep mode, and the main controller STM32L041G6U6STR automatically enters a low-power state, and sets the gyroscope sensor to a motion trigger state. Once the gyroscope sensor detects that the UWB beacon is moving, the UWB communication circuit DW1000 and the STM32L041G6U6STR main control chip are awakened, and the UWB antenna is controlled to start working, thereby reducing the power consumption of the UWB beacon.

[0135] The solar voltage detection circuit detects the voltage output by the solar panel to determine the intensity of sunlight. The stronger the sunlight, the greater the voltage output by the solar panel. Figure 2As shown in the figure, the intensity of sunlight is obtained by detecting the output voltage of the solar panel, and the voltage signal is input to the controller STM32L041G6U6STR. The voltage signal is sampled by the 12-bit ADC inside the STM32L041G6U6STR, and then the analog signal of the power supply voltage is converted into a mathematical signal to realize intelligent detection of sunlight intensity.

[0136] In this embodiment, a solar panel is arranged on the surface of the UWB beacon to fully absorb solar light. After absorbing sunlight, the solar panel on the surface of the UWB beacon can convert solar energy into electrical energy, which is then used to replenish and charge the UWB beacon battery and power the UWB circuit after voltage stabilization and filtering. The gyroscope sensor is used to detect the status of the UWB beacon, which solves the problems of high power consumption and short battery life of the UWB beacon.

[0137] In practical applications, when the mobile device is a UWB beacon, the UWB beacon is mainly composed of a shell with a surface made of single crystal silicon material, a 3.7V polymer lithium battery pack and a PCB circuit motherboard. The structure of the UWB beacon is shown in Figure 8(a) and Figure 8(b). Figure 8(a) shows the structure of the UWB beacon, which is mainly composed of a UWB beacon base, a PCB circuit board, a 3.7V lithium battery and a shell designed with solar single crystal silicon material. Figure 8(b) shows the complete assembled UWB beacon, whose A surface (front and back left and right sides and the top surface) are all designed with single crystal silicon solar energy.

[0138] In FIG. 8( a ), 601 denotes a base member of a UWB beacon; 602 denotes a 3.7V lithium battery; 603 denotes a PCB circuit board; and 604 denotes a housing with solar monocrystalline silicon material.

[0139] In FIG8( b ), A represents a surface with solar monocrystalline silicon, and all five surfaces are designed with solar monocrystalline silicon.

[0140] In this embodiment, the outer shell surface of the UWB beacon adopts a single silicon crystal design, and sunlight is irradiated on the surface monocrystalline silicon of the UWB beacon to generate electricity. The generated electricity is stabilized and used to replenish and charge the battery of the UWB beacon, or to power the UWB beacon circuit. At the same time, based on comprehensive conditions such as power detection, UWB motion status detection, sunlight intensity, and beacon power consumption, the solar power supply channel and charging channel are intelligently and automatically selected to achieve solar intelligent charging and UWB beacon intelligent discharge, reduce the total circuit power consumption, increase the efficient conversion of solar energy and the low energy consumption of the UWB beacon, and reduce the frequency of manual charging.
