[0009] When in the second mode, if a second conversion signal is obtained, the control unit determines that the power module enters the first mode;

[0010] Wherein, in the second mode, when the power-consuming module is powered, it can only be powered by part of the energy storage module.

[0014] When in the first mode, if a first conversion signal is obtained, determining that the power module enters the second mode;

[0015] When in the second mode, if a second conversion signal is obtained, determining that the power module enters the first mode;

[0016] Among them, in the second mode, when the power module is powered, it can only be powered by part of the energy storage module

[0017] According to a third aspect of the present invention, there is provided an electronic device comprising a processor and a memory,

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0072] The terms "first," "second," "third," "fourth," and so on (if any) in the description and claims of the present invention and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in orders other than those illustrated or described herein. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product, or apparatus.

[0073] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0074] Please refer to Figure 1 , and in combination with other drawings, an embodiment of the present invention provides a power supply circuit, including:

[0075] A transducer 1 adapted to induce non-electrical energy to generate electrical energy;

[0076] Energy storage component 2, which is directly or indirectly operatively connected to the transducer and is configured to receive and store the electrical energy; the "operative connection" herein can be understood as a connection method suitable for transmitting electrical signals between the transducer 1 and the energy storage component 2, so that when the transducer generates electrical energy, the energy storage component 2 can complete the task of "receiving and storing electrical energy." In addition, in some of the solutions, during the process of the energy storage component 2 receiving and storing electrical energy, at least one of the power supply component 3 and the power consumption module 4 can be introduced to control, guide, guarantee, and assist the process of "receiving and storing the electrical energy."

[0077] The power supply component 3 is electrically connected between the energy storage component 2 and a power module 4 and is configured to monitor the output voltage of the energy storage component 2, thereby:

[0078] When the power module 4 is in a non-powered state and the output voltage is within a specified voltage range, the energy storage component 2 does not supply power to the power module 4, thereby forming a pre-power supply stage;

[0079] When the output voltage is in a non-specified voltage range, the energy storage component supplies power to the power-consuming module, thereby forming a power supply stage.

[0080] The phrase "being in a non-specified voltage range" can be understood as meaning "not being in the specified voltage range." The specified voltage range can be understood as any pre-specified voltage range or a voltage range specified during operation. The specified voltage range can be characterized by an upper voltage threshold and / or a lower voltage threshold. In one example, the specified voltage range can be a range less than (or not greater than) a first voltage threshold.

[0081] The first voltage threshold matches the electric energy required for the power-consuming module to complete one power-on.

[0082] The transducer can be an energy converter that converts any one or more of light energy, electromagnetic wave energy, vibration energy, and thermal energy into electrical energy. In a further example, the transducer includes a solar panel. The length and width of the solar panel are X and Y, respectively; where X ranges from [30 mm to 40 mm] and Y ranges from [10 mm to 16 mm]. In some examples, the solar panel can be an amorphous silicon low-light solar panel. Compared to conventional solar panels, this type of solar panel can effectively collect light energy in low-light environments.

[0083] In the above scheme, since the power module is in a non-powered state and the output voltage does not need to power the power module when it is in a specified voltage range, at this time, even if the energy storage component receives and stores the electrical energy of the transducer, it will not output it to the power module, which can help to prioritize meeting the energy storage needs when it is in a non-powered state and the stored electrical energy is low. Compared with the scheme of storing energy and supplying power at the same time, this scheme can effectively improve the charging efficiency of the energy storage component before the power module is powered on, and realize efficient charging of the energy storage component before the power module is powered on. On this basis, since the power module must be powered on with a certain voltage, in this scheme, the power module can be powered on as soon as possible, the startup speed of the power module can be improved, and the power module can be started quickly.

[0084] In one implementation, please refer to Figure 2 、 Figure 3 , and other figures, the energy storage component 2 includes a first energy storage module 201 and a second energy storage module 202; the power supply component 3 includes a power supply module 304. In other examples, the number of energy storage modules can also be three or more.

[0085] The first energy storage module 201 and the second energy storage module 202 can be any device or combination of devices with energy storage capabilities. For example, the first energy storage module includes at least one capacitor (e.g. Figure 14 、 Figures 7 to 11 The capacitor C6 shown, which may be a tantalum capacitor, is used to quickly store electrical energy. The second energy storage module 202 includes at least one supercapacitor or a rechargeable battery (e.g. Figure 14 、 Figures 7 to 11 The capacitor C1 shown in FIG2 is a block diagram of a capacitor C1; furthermore, the capacity of the second energy storage module must be at least greater than that of the first energy storage module.

[0086] In a specific example, the capacitance range of the first energy storage module 201 is 470µF to 1000µF, and the capacitance range of the second energy storage module 202 is 0.2F to 0.5F. Furthermore, the capacitance of the first energy storage module 201 is set to 470µF, and the capacitance of the second energy storage module 202 is set to 0.25F.

[0087] The input side of the power supply module 304 is directly or indirectly connected to the first end of the first energy storage module 201 and the first end of the second energy storage module 202, and the output side of the power supply module 304 is connected to the power consumption module 4; that is, the power supply module 304 is arranged in the power supply path between the energy storage component 2 and the power consumption module 4.

[0088] The power supply module 304 is configured to disconnect the power supply path between the energy storage assembly 2 (i.e., the first energy storage module 21 and the second energy storage module 22) and the power consumption module 4 when the power consumption module 4 is not powered on and if it is detected that the voltage of the first energy storage module 201 is within the specified voltage range, thereby forming the pre-power supply stage.

[0089] After the power-consuming module 4 is powered on, the electric energy stored in the first energy storage module 21 and / or the second energy storage module 22 is supplied to the power-consuming module 4 , thereby forming the power supply stage.

[0090] For further information, please refer to Figure 2 , the power supply component 3 includes a first on-off module 301 .

[0091] The first end of the second energy storage module 202 is electrically connected to the first end of the transducer 1 through the first on-off module 301; the first on-off module 301 is configured to remain disconnected during the pre-power supply stage, so that the transducer 1 only charges the first energy storage module 201 during the pre-power supply stage, so that the first energy storage module 201 can quickly store electrical energy during the pre-power supply stage.

[0092] The rapid storage of electrical energy can be understood as follows: when charging the energy storage component using the transducer, the charging speed of charging only the first energy storage module 201 is faster than the charging speed of charging both the first energy storage module 201 and the second energy storage module 202 simultaneously. In the above solution, when two energy storage modules are introduced, the control of the first on-off module 301 allows the energy storage component to complete the required charging as quickly as possible during the pre-power supply phase (for example, charging to the first voltage threshold so that the output voltage meets the power-on requirements of the power-consuming module). As a result, the power-consuming module can be powered on as quickly as possible, improving the startup speed of the power-consuming module and achieving rapid startup of the power-consuming module.

[0093] It can be seen that the specific solution of the present invention provides two energy storage modules of different sizes (i.e., the first energy storage module 201 and the second energy storage module 202), wherein the first energy storage module 201 is a small-capacity energy storage module (capable of being quickly charged), and the second energy storage module 202 is a large-capacity storage device (large-capacity capacitor, rechargeable battery, etc.); the minimum capacity of the first energy storage module 201 is sufficient to complete a power-on initialization of the power-consuming module.

[0094] Furthermore, the first on-off module 301 includes a first control terminal and a second control terminal, and is configured to be turned on when the first control terminal and the second control terminal are triggered at the same time; furthermore, when either the first control terminal or the second control terminal of the first on-off module 301 is not triggered, the first on-off module 301 will be turned off. The second energy storage module is configured to receive and store the electrical energy generated by the transducer when the first on-off module is turned on;

[0095] The first control terminal of the first on-off module 301 is configured to be triggered by receiving a specified voltage level during the power supply phase.

[0096] In one approach, referring to Figure 2 As shown, the first control end of the first on-off module 301 can be triggered after the power-consuming module is powered on, so that it is turned on, thereby using the transducer to power the second energy storage module; for example: the first control end of the first on-off module 301 is electrically connected to the power-consuming module and is configured to be triggered by receiving a specified level (high level or low level) during the power supply stage under the control of the power-consuming module.

[0097] However, when two energy storage modules, a first energy storage module and a second energy storage module (for example, two capacitors of different sizes), are used, starting from the time when both capacitors are out of power, the first energy storage module (for example, the small capacitor) needs to be charged first. After the voltage of the small capacitor exceeds a certain threshold (a voltage greater than the minimum operating voltage, that is, greater than the first voltage threshold), the power-consuming module is powered and started, and the charging circuit of the second energy storage module (for example, the large capacitor) is opened to charge the second energy storage module (for example, the large capacitor). This can be achieved by controlling the first on-off module to be turned on.

[0098] However, when the second energy storage module is completely out of power or seriously depleted, the power will be turned on because the load starts working after the first energy storage module is charged to the threshold. Subsequently, once the charging circuit is opened, the voltage difference between the large capacitor and the small capacitor is relatively large (the voltage of the large capacitor is relatively low). At this time, the charging current will be relatively large, but because the current provided by some transducers (such as solar panels in low light environments) is very small, almost all the energy generated is used to charge the second energy storage module (such as the large capacitor). As time goes by, the voltage of the first energy storage module (such as the small capacitor) will gradually decrease until it is lower than the working threshold, and the system will shut down.

[0099] Therefore, in order to solve this problem, in one embodiment, a set threshold is introduced, and the first control end of the first on-off module is set to: when the voltage of the first energy storage module is higher than the specified threshold, it receives the specified level and is triggered; the specified threshold matches the minimum operating voltage.

[0100] It can be seen that after the voltage of the first energy storage module (such as a small capacitor) is higher than the first voltage threshold, the power module charges the second energy storage module (such as a large capacitor) only after the voltage of the first energy storage module (such as a small capacitor) is higher than the specified threshold.

[0101] The first control terminal of the first on-off module 301 is configured to be triggered by receiving the specified level when the voltage of the first energy storage module is higher than a specified threshold; the specified threshold matches the minimum operating voltage.

[0102] In one example, referring to Figure 2 The control based on the specified threshold can be achieved through the power module 4. The power module is configured to output the specified level to the first control end of the first on-off module during the power supply stage when the voltage of the first energy storage module is higher than the specified threshold, so as to trigger the first control end of the first on-off module.

[0103] It can be seen that in the above solution, if the on-off change of the first on-off module 301 is realized based on the control of the power module, it can be ensured that the second energy storage module can be triggered to turn on only after the power module is powered on.

[0104] In order to realize the detection of the voltage of the first energy storage module by the power module, in a specific example, the Figure 35 The acquisition module shown may include: a transistor Q5A and a driving transistor Q6A. The first end of the driving transistor Q6A is connected to the gate of the transistor Q5A. A resistor R4 is provided between the first end and the gate of the transistor Q5A. The first end of the transistor Q5A can be connected to the first energy storage module to collect the voltage of the first energy storage module. The second end of the transistor Q5A is grounded via a resistor R25 and a resistor R23. Furthermore, the resistors R25 and R23 can achieve voltage division to form a voltage VTAIN, which can be input to the control unit to represent the voltage of the first energy storage module. The control unit of the power consumption module is connected between the resistors R25 and R23. The control end of the driving transistor Q6A is grounded via a resistor R24. The control end of the driving transistor Q6A is also connected to the control unit via a resistor R15 to receive a control signal.

[0105] This control signal can be used to control the driver Q6A to conduct when measurement is required. The control unit measures the voltage of the first energy storage module (e.g., a small capacitor) after it is divided by resistors R25 and R23 to obtain the voltage of the first energy storage module (e.g., a small capacitor). Furthermore, the control unit (e.g., an MCU) can control the charging circuit of the second energy storage module (e.g., a large capacitor) in real time based on the voltage of the first energy storage module (e.g., a small capacitor) to ensure that the first energy storage module does not drop below the minimum operating voltage, causing a shutdown. Figure 35The AD_Ctr2 pin can be connected to a control unit (such as an MCU) to control the on / off of the driver Q6A, and the VTAIN pin is connected to a control unit (such as an MCU) to obtain the voltage MCUPW of the first energy storage module (such as a small capacitor).

[0106] In another example, the control based on the specified threshold can also be implemented by the charging judgment detection module. Figure 34 For example, the power supply component further includes a charging judgment detection module 309, the input end of the charging judgment detection module 309 is electrically connected to the first end of the first energy storage module, and the output end is electrically connected to the first control end of the first on-off module 301;

[0107] The charging determination detection module 309 is configured to:

[0108] In the power supply phase, when the voltage of the first energy storage module is higher than the specified threshold, the specified level is output to the first control terminal of the first switching module to trigger the first control terminal of the first switching module.

[0109] In this solution, the on-off control of the first on-off module no longer depends on the power module, which can prevent the control result from being affected by the working state of the power module.

[0110] In a specific example, the charging judgment detection module 309 can be implemented using a voltage comparator or a voltage detection chip. The charging circuit of the second energy storage module (e.g., a large capacitor) can be controlled by the voltage comparator or the voltage detection chip; that is, the output of the voltage comparator or the voltage detection chip can be used for large capacitor charging control.

[0111] The voltage detection chip can be, for example, Figure 36 The voltage detection chip 3091 shown in FIG. 3 and the capacitors C31 and C30 connected to the voltage detection chip 3091 can be used to refer to FIG. Figure 17 Understand the filter capacitor Cf2 and capacitor C7.

[0112] Among them, when based on the specified threshold control, there may be no hysteresis effect (in this case, the specified threshold can be set to 2.4V), or there may be a hysteresis effect (for example, the hysteresis voltage can be set to 200mV, that is, forming an upper limit of 2.5V and a lower limit of 2.3V). When the voltage detection chip 3091 is used to control the charging circuit of the second energy storage module, the hysteresis function of the voltage detection chip 3091 can be used to achieve the hysteresis effect. When a control unit (such as an MCU) is used to monitor the voltage of the first energy storage module (such as a small capacitor), the hysteresis effect can be achieved through software programming.

[0113] The signal connected to the second control terminal of the first on-off module 301 can be associated with the voltage of the second energy storage module, thereby enabling the on-off control of the first on-off module 301 to match the actual voltage of the second energy storage module. In a specific solution, the power supply component 3 further includes an energy storage detection module 303;

[0114] The input end of the energy storage detection module 303 is electrically connected to the first end of the second energy storage module 202 (for example, capacitor C1), and the output end is electrically connected to the second control end of the first on-off module 301. The energy storage detection module 303 is configured to monitor the voltage of the second energy storage module and output a voltage level for shutting off the first on-off module to the second control end when the voltage of the second energy storage module 202 reaches a second voltage threshold. Furthermore, when the voltage of the second energy storage module 202 does not reach the second voltage threshold, the energy storage detection module 303 can trigger the second control end of the first on-off module 301. In this case, the first on-off module may be turned on.

[0115] visible:

[0116] In the above example, the following two conditions must be met simultaneously for the first on / off module 301 to be triggered to turn on: Condition 1: The power consumption module 4 outputs a specified voltage level to the first control terminal of the first on / off module, thereby triggering the first control terminal; Condition 2: The energy storage detection module 303 triggers the second control terminal of the first on / off module because the voltage of the second energy storage module 202 does not reach the second voltage threshold. Failure to meet either of these two conditions will cause the first on / off module 301 to turn off, preventing the second energy storage module from being charged. The second voltage threshold matches the voltage of the second energy storage module when it is fully charged. For example, it can be this voltage itself, or a voltage value slightly lower (or higher) than this voltage.

[0117] Furthermore, the second energy storage module 202 can stop being charged after being fully charged, effectively avoiding the occurrence of overcharging, thereby protecting the second energy storage module 202 .

[0118] In some examples, the first on-off module 301 may also be controlled only by the power-consuming module 4 (e.g., its control unit). For example, the power-consuming module is connected to the energy storage detection module 303, and then, the first on-off module 301 may be controlled based on the detection results. The control logic of the first on-off module 301 may be understood with reference to the above description.

[0119] For an example, please refer to Figure 17 The energy storage detection module 303 includes an energy storage voltage detection chip 3031, the functions of which can be understood as including Figure 18 The function of the energy storage detection comparator 3032 shown in FIG. 3 can also be realized in some solutions. Figure 18The energy storage detects part or all of the functions of the sliding rheostat R, the reference voltage unit 3033, etc.

[0120] In one implementation, please refer to Figure 16 The input end of the energy storage voltage detection chip 3011 (which may be the first input end of the energy storage detection comparator 3032 or connected to the first input end) is directly or indirectly connected to the first end of the second energy storage module 202, and the output end is directly or indirectly connected to the second control end of the first on-off module 301, so that when the voltage of the second energy storage module reaches the second voltage threshold, the output end of the energy storage voltage detection chip 3011 outputs a voltage level for shutting off the first on-off module 301 to the second control end of the first on-off module.

[0121] A first filter element (e.g., filter capacitor Cf2) is further connected between the ground pin and the input end (i.e., one end connected to the second energy storage module) of the energy storage voltage detection chip 3011. The first filter element is used to filter the input voltage signal at the input end of the energy storage voltage detection chip.

[0122] Figure 17 In the illustrated embodiment, a first unidirectional conducting unit (e.g., comprising a diode D3) is further connected between the output end of the energy storage voltage detection chip 3031 and the second control end of the first on-off module 301. The input end of the first unidirectional conducting unit is connected to the output end of the energy storage voltage detection chip 3031, and the output end of the first unidirectional conducting unit (e.g., comprising a diode D3) is connected to the second control end of the first on-off module 301. The first unidirectional conducting unit can prevent the output end of the energy storage voltage detection chip from receiving a reverse voltage, which could damage the energy storage voltage detection chip.

[0123] The first unidirectional conducting unit may include a diode D3 ; the anode of the diode D3 is electrically connected to the input terminal of the energy storage voltage detection chip 3031 , and the cathode is electrically connected to the second control terminal of the first on-off module 301 .

[0124] In a solution not shown, the first unidirectional conducting unit may also include a transistor and a first pull-up resistor and a first pull-down resistor matching the transistor; the first pull-up resistor is connected between the collector and base of the transistor, and the base of the transistor is grounded via the first pull-down resistor; the collector of the transistor is also electrically connected to the output terminal of the energy storage voltage detection chip, and the emitter of the transistor is electrically connected to the second control terminal of the first on-off module. The transistor may also be replaced with other transistors.

[0125] In one implementation, please refer to Figure 18The energy storage detection module 303 includes an energy storage detection comparator 3032, a first input end of the energy storage detection comparator 3032 is directly or indirectly connected to the first end of the second energy storage module 202, and a second input end of the energy storage detection comparator 3032 is connected to the reference voltage corresponding to the second voltage threshold; the output end of the energy storage detection comparator 3032 is connected to the second control end of the first on-off module 301, so that when the voltage of the second energy storage module reaches the second voltage threshold, the output end of the energy storage detection comparator 3032 outputs a level for shutting off the first on-off module to the second control end of the first on-off module 301.

[0126] The reference voltage may be provided by a reference voltage unit 3033, which may be any circuit capable of providing a reference voltage. For example, a reference voltage may be formed by a current source and a resistor connected in series, or by a voltage stabilizer, a transformer, or other devices.

[0127] In a further example, the energy storage detection module 303 further includes an energy storage detection sliding rheostat R.

[0128] The active end of the energy storage detection sliding rheostat R is connected to the first input end of the energy storage detection comparator R, the first end of the energy storage detection sliding rheostat R is directly or indirectly connected to the second energy storage module 202, and the second end of the energy storage detection sliding rheostat R is grounded.

[0129] In this circuit, Vref is a given reference voltage, PWLINE2 is the sampled voltage of the second energy storage module, which represents the voltage of the second energy storage module, Vin is the input voltage of the comparator, and PWCHECK is the second control terminal output to the first on-off module;

[0130] When Vin > Vref, the voltage of the second energy storage module exceeds the second voltage threshold. At this point, PWCHECK outputs a high level, shutting down the first on-off module. Conversely, it outputs a low level, turning on the first on-off module. The sliding rheostat R can be used to adjust the voltage relationship between Vin and PWLINE2. Furthermore, the energy storage voltage detection chip 3031 can be connected to the second control terminal of the first on-off module 301 via a diode D3, with the anode of diode D3 connected to the energy storage voltage detection chip 3031.

[0131] In other examples, the energy storage voltage detection chip 3031 may also be a chip capable of detecting the voltage value of the second energy storage module, such as an analog-to-digital conversion chip, and is not limited to an energy storage voltage detection chip that implements a comparator function.

[0132] In one embodiment, the power supply module is specifically configured to, when the power-consuming module is not powered on, if it is detected that the voltage of the first energy storage module has not reached a specified first voltage threshold, keep disconnecting the power supply circuit between the first energy storage module, the second energy storage module, and the power-consuming module, thereby forming the specified voltage interval with the first voltage threshold as the end point;

[0133] If it is detected that the voltage of the first energy storage module reaches a specified first voltage threshold, the electric energy stored in the first energy storage module starts to be supplied to the power-consuming module to power on the power-consuming module.

[0134] In one implementation, please refer to Figure 3 , and in combination with other drawings, the power supply component 3 further includes:

[0135] A second on-off module 305 , connected between the first end of the second energy storage module 202 and the input side of the power supply module 304 ;

[0136] The power consumption module 4 is also configured to control the second on-off module 305 to be turned on during the power supply stage (for example, all or part of the time during the power supply stage); wherein, when the second on-off module 305 is turned on, the electric energy stored in the second energy storage module 202 can be supplied to the power consumption module 4 by the power supply module 304.

[0137] For further information, please refer to Figure 3 The power-consuming module 4 (e.g., its control unit 401) is further electrically connected to the first end of the second energy storage module 202 to monitor the voltage of the second energy storage module 202 (which can represent the amount of electricity in the second energy storage module). When the voltage of the second energy storage module reaches a preset third voltage threshold, the second on-off module is controlled to be turned on, so that the electric energy of the second energy storage module 202 can be supplied to the power-consuming module by the power supply module.

[0138] In some solutions, the power module 4 can directly sample the second energy storage module 202 to detect its voltage, and it is not ruled out that the voltage of the second energy storage module 202 can be detected in combination with other circuits. For example, an analog-to-digital conversion module can also be provided between the power module 4 and the second energy storage module 202.

[0139] In a solution using the first on-off module and the second on-off module, in a specific solution, at the start of operation, both the first energy storage module 201 and the second energy storage module 202 have no power (or have a small amount of power, but not enough to power the load), and need to be charged by the solar panel. At this time, the power supply module cuts off the path for the first energy storage module to supply power to the power supply module. At the same time, the first on-off module 301 is also disconnected, so that the charging path from the solar panel to the second energy storage module 202 is also disconnected, so that the power of the solar panel can be concentrated to charge the first energy storage module 201. Since the first energy storage module 201 has a small capacity, it can be quickly charged to a voltage that meets the startup voltage of the load (i.e., the power module) (energy can be stored quickly even in low light conditions).

[0140] When it is detected that the voltage of the first energy storage module is higher than the first voltage threshold (greater than the minimum operating voltage of the power module), the power supply module is turned on, and the first energy storage module 201 can supply power to the power module. The power module starts working. If the power module is equipped with a sensor, the status of the sensor can be detected and a signal can be sent through the wireless module.

[0141] After the power-consuming module is powered on, the control unit in the power-consuming module controls the first on-off module 301 to be turned on, so that the second energy storage module 202 starts to store energy, and monitors the voltage of the second energy storage module 202 in real time to prevent the second energy storage module 202 from being overcharged. When it is detected that the second energy storage module 202 is full, the control unit controls the first on-off module 301 to be turned off.

[0142] When the solar panel output energy decreases (for example, when there is no sunlight after dark), the second on-off module 305 is turned on, and the energy of the second energy storage module 202 can be automatically supplemented to the first energy storage module 201 through the corresponding path for use by the load, so that the load can continue to work in a dark environment.

[0143] In one embodiment, in order to realize the control based on the first voltage threshold, the power supply module may be configured with a circuit unit with a detection function (such as a power supply detection unit). For details, please refer to Figure 3 , the power supply module 304 includes a power supply unit 3041 and a power supply detection unit 3042;

[0144] The input side of the power supply unit 3041 is directly or indirectly connected to the first end of the first energy storage module 201 and the first end of the second energy storage module 202, and the output side of the power supply unit 3041 is connected to the power supply end of the power consumption module 4 (for example, directly or indirectly connected to the power supply end of the control unit 401 and the wireless unit 404); the power supply detection unit 3042 is connected to the input side of the power supply unit 3041, and the power supply detection unit 3042 is also connected to the trigger end of the power supply unit 3041;

[0145] The power supply detection unit 3042 is configured to monitor the voltage at the input side of the power supply unit during the pre-power supply phase and use the voltage as the voltage of the first energy storage module 201;

[0146] When it is detected that the voltage of the first energy storage module 201 does not reach a specified first voltage threshold (i.e., is lower than the first voltage threshold), the power supply unit is not triggered, so that the power supply unit remains disconnected in the specified voltage range (i.e., the power supply path from the energy storage component to the power consumption module is disconnected);

[0147] When it is monitored that the voltage of the first energy storage module 201 reaches a specified first voltage threshold, a specified level is output to trigger the power supply unit to start working, so that the power-consuming module is powered on and initialized.

[0148] Furthermore, the second on-off module 305 is connected between the first end of the second energy storage module 202 and the input end of the power supply unit 3041;

[0149] When the second on-off module 305 is disconnected, the power supply unit 3041 supplies the electric energy stored in the first energy storage module 201 to the power consumption module 4;

[0150] When the second on-off module 305 is turned on, the power supply unit 3041 supplies the electric energy stored in the first energy storage module 201 and the second energy storage module 202 to the power consumption module.

[0151] exist Figure 16 In the example shown, the power supply detection unit 3042 includes a power supply voltage detection chip 30421; the functions implemented by it can be understood as including the functions of the power supply detection comparator described later. In some schemes, it can also implement some or all of the functions of the power supply detection sliding resistor and the corresponding reference voltage unit described later.

[0152] The input end of the supply voltage detection chip 30421 is directly or indirectly connected to the first end of the first energy storage module 201 (for example, capacitor C6), and the output end is directly or indirectly connected to the trigger end of the power supply unit 3041. When the voltage of the first energy storage module 201 reaches the first voltage threshold, the output end of the supply voltage detection chip 30421 outputs a specified voltage level (i.e., a DCDCEN signal of a specified voltage level), thereby triggering the power supply unit to start operating.

[0153] In addition, the designated levels output by the power supply voltage detection chip 30421 and the energy storage voltage detection chip 3031 may be the same level or different levels.

[0154] exist Figure 16In the example shown, a second filter element (eg, filter capacitor Cf1 ) is connected between the ground pin and the input end of the power supply voltage detection chip 30421 . The second filter element is used to filter the input voltage signal of the input end of the power supply voltage detection chip.

[0155] In addition, the CT terminal of the power supply voltage detection chip 30421 is grounded via capacitor C27 to achieve time delay of the power supply voltage detection chip 30421. The CT terminal of the energy storage voltage detection chip 3031 is grounded via capacitor C7 to achieve time delay of the energy storage voltage detection chip 3031.

[0156] In an example not shown, referring to the energy storage voltage detection chip 3031, a second unidirectional conduction unit is further connected between the output end of the supply voltage detection chip 30421 and the trigger end of the power supply unit 3041. The input end of the second unidirectional conduction unit is connected to the output end of the supply voltage detection chip, and the output end of the second unidirectional conduction unit is connected to the trigger end of the power supply unit to prevent the output end of the supply voltage detection chip from inputting a reverse voltage and damaging the supply voltage detection chip.

[0157] In a further example, the second unidirectional conducting unit includes a diode; the anode of the diode is electrically connected to the input terminal of the power supply voltage detection chip, and the cathode is electrically connected to the trigger terminal of the power supply unit. In a further another example, the second unidirectional conducting unit includes a transistor and a second pull-up resistor and a second pull-down resistor matching the transistor; the second pull-up resistor is connected between the collector and base of the transistor, and the base of the transistor is grounded through the second pull-down resistor; and the collector of the transistor is also electrically connected to the output terminal of the power supply voltage detection chip, and the emitter of the transistor is electrically connected to the trigger terminal of the power supply unit.

[0158] Reference Figure 18 The energy storage detection comparator shown, the power supply detection unit may include a power supply detection comparator; the first input end of the power supply detection comparator is directly or indirectly connected to the first end of the first energy storage module, and the second input end of the power supply detection comparator is connected to the reference voltage corresponding to the first voltage threshold; the output end of the power supply detection comparator is connected to the trigger end of the power supply unit. Furthermore, the power supply detection unit also includes a power supply detection sliding resistor;

[0159] The active end of the power supply detection sliding resistor is connected to the first input end of the power supply detection comparator, the first end of the power supply detection sliding resistor is directly or indirectly connected to the input side of the power supply unit, and the second end of the power supply detection sliding resistor is grounded.

[0160] In one embodiment, when the power supply unit supplies the electric energy stored in the first energy storage module and / or the second energy storage module to the power consumption module, it is specifically configured to:

[0161] The voltage on the input side of the power supply unit is converted to obtain a converted voltage, and the electric energy of the converted voltage is output to the power-consuming module, so that the output power has an electric energy with a voltage suitable for the operation of the power-consuming module, thereby making the output voltage meet the requirements of the power-consuming module.

[0162] In one embodiment, the power supply unit includes at least one conversion unit, and the number of the conversion units is, for example, Figure 4 、 Figure 10 、 Figure 11 The two conversion units shown (for example, a first conversion unit 30411 using a switching power supply 304110 and a second conversion unit 30412 using a linear regulator 304120) are also shown. Figure 8 、 Figure 9 A conversion unit is shown (for example, a conversion unit using a switching power supply 304110); the input side of the conversion unit is directly or indirectly connected to the first end of the first energy storage module 201 and the first end of the second energy storage module 202, and the output side of the conversion unit is connected to the power supply end of the power-consuming module 4; the conversion unit is configured to perform the voltage conversion when triggered to work, for example, it can be triggered by the power supply detection unit 3042.

[0163] In a further solution, Figure 4 、 Figure 10 and Figure 11 For example, the at least one transformation unit includes a plurality of different transformation units;

[0164] The power supply detection unit is further used to detect the voltage on the input side of the power supply unit after the power-consuming module is powered on, and to selectively trigger the conversion unit to operate according to the voltage on the input side of the power supply unit.

[0165] Furthermore, since the conversion capabilities or voltages suitable for conversion of different conversion units are different, the above-mentioned selective triggering method can effectively ensure that the conversion process and conversion results can accurately match the actual power supply requirements.

[0166] The multiple conversion units include a first conversion unit 30411; the first conversion unit 30411 is configured as a switching power supply 304110; an enable terminal of the switching power supply 304110 is a trigger terminal of the power supply unit 3041;

[0167] When the power supply detection unit 3042 triggers the conversion unit to operate according to the voltage at the input side of the power supply unit, it is specifically used to:

[0168] When the voltage at the input side of the power supply unit 3041 is lower than the preset conversion unit switching threshold, the first conversion unit is triggered to operate.

[0169] The switching power supply may be a step-down DC-DC switching power supply, which can be powered to output electric energy with a stable voltage to the power-consuming module.

[0170] In a further embodiment, the plurality of conversion units further include a second conversion unit 30412; the second conversion unit 30412 is configured as a linear regulator 304120; the enable terminal of the linear regulator 304120 is the trigger terminal of the power supply unit;

[0171] Generally speaking, the voltage difference between the input and output of a DC-DC switching power supply is usually greater than the voltage difference between the input and output of a linear regulator (LDO). Therefore, when the voltage output to the power-consuming module is fixed, the DC-DC switching power supply or linear regulator can be adaptively selected to match the input voltage. On this basis, the power loss of the power supply unit can be effectively reduced. When the power supply detection unit triggers the operation of the conversion unit based on the voltage on the input side of the power supply unit, it is specifically used to:

[0172] When the voltage at the input side of the power supply unit is higher than the switching threshold of the conversion unit, the second conversion unit is triggered to operate.

[0173] In addition to selecting one of the conversion parts, a conversion part switching part can also be introduced into the circuit to avoid the problem of simultaneous power supply caused by the conversion part failing to complete triggering and stopping triggering in time, thereby ensuring safety. Furthermore, the power supply unit 3041 also includes a conversion part switching part 30413, a first node of the conversion part switching part 30413 is directly or indirectly connected to the first end of the first energy storage module 201 (for example, capacitor C6) and the first end of the second energy storage module 202 (for example, capacitor C1), a second node of the conversion part switching part 30413 is connected to the input side of the first conversion part 30411 (for example, switching power supply 304110), and a third node of the conversion part switching part 30413 is connected to the input side of the second conversion part 30412 (for example, linear regulator 304120); the power supply detection unit 3042 and the control end of the conversion part switching part are also connected to the power consumption module;

[0174] The number of nodes of the conversion unit switching unit 30413 can be three, but is not limited to three, for example, can be four or more.

[0175] The conversion unit switching unit 30413 is used to:

[0176] When the voltage at the input side of the power supply unit is greater than the switching threshold of the conversion unit, the first node and the second node are connected under the control of the power consumption module;

[0177] When the voltage at the input side of the power supply unit is less than or equal to the switching threshold of the conversion unit, the first node and the third node are connected under the control of the power consumption module to reduce the power loss of the power supply unit.

[0178] The conversion unit switching unit may include a first transistor and a second transistor; the first transistor and the second transistor may refer to Figure 12 The transistor Qa shown is understood from the transistor Qb.

[0179] The first end of the first transistor and the first end of the second transistor are connected to form a first node (eg, Figure 12 ), the second end of the first transistor forms the second node of the conversion section switching section (eg Figure 12 The node at the lower end of the transistor Qa shown in FIG), the second end of the second transistor forms the third node of the switching portion of the conversion portion (eg Figure 12 Node at the lower end of transistor Qb shown in );

[0180] The control end of the first transistor (for example, the M end) is connected to the power module, and the control end of the second transistor is connected to the power module via an inverter, or: the control end of the second transistor is connected to the power module, and the control end of the first transistor (for example, the M' end) is connected to the power module via an inverter.

[0181] Furthermore, when the first transistor is turned on, the second transistor is turned off, and the corresponding two nodes are connected; when the second transistor is turned on, the first transistor is turned off, and the corresponding two nodes are connected.

[0182] In the above schemes, the enabling or disabling of the conversion part in the power supply unit can control the on-off of the power supply path. In some other schemes, a conversion part and a switch can be connected in series, and then the on-off of the power supply path can be controlled by the on-off of the switch.

[0183] In one embodiment, the trigger end of the power supply unit can also be directly connected to the output voltage of the energy storage component, and thus directly controlled by the output voltage of the energy storage component instead of being controlled based on (or not only based on) the detection result of the power supply detection unit. For example, the output voltage of the energy storage component can be connected to the enable end (i.e., Enable pin) of the DC-DC switching power supply (and / or linear regulator LDO). When the output voltage is lower than the enable threshold of the enable end, the DC-DC switching power supply (and / or linear regulator LDO) has no output, and the back-end circuit (such as the power consumption module) does not work; when the output voltage is higher than the enable threshold of the enable end, the DC-DC switching power supply (and / or linear regulator LDO) has an output, and the back-end circuit (such as the power consumption module) works. At this time, the enable threshold can also be understood as the first voltage threshold.

[0184] In some solutions, the power supply voltage detection chip of the power supply detection unit can directly output a signal to the trigger end of the power supply unit (for example, the enable end of the DC-DC switching power supply and / or the linear regulator LDO). If the power supply unit does not have a trigger end, the power supply voltage detection chip can also output a signal to a transistor (for example, a MOS tube), and then control whether the power supply unit supplies power by turning the transistor (for example, a MOS tube) on and off.

[0185] Furthermore, the power supply unit and power supply detection unit (e.g., the function of a DC-DC switching power supply) described above can be integrated with the control unit in the power-consuming module. That is, the power supply unit, power supply detection unit, and the control unit in the power-consuming module can form an integrated circuit, which can also be considered a control unit. As long as the functions implemented are the same or similar to those in the embodiments of the present invention, whether the circuit is discrete, integrated, or formed in another manner does not depart from the scope of the embodiments of the present invention.

[0186] In one implementation, please refer to Figure 5 The power supply assembly further includes a first charging unidirectional conduction portion 306, the input end of the first charging unidirectional conduction portion 306 is connected to the first end of the transducer 1, and the output end of the first charging unidirectional conduction portion 306 is directly or indirectly connected to the first end of the first energy storage module 201 and the first end of the second energy storage module 202. For further information, please refer to Figures 7 to 11 、 Figure 14 The first unidirectional charging conduction unit 306 may include at least one first charging diode D11. If at least two first charging diodes are included, the first charging diodes may be connected in series. In an example not shown, the first unidirectional charging conduction unit 306 includes at least one first charging transistor, thereby achieving the unidirectional conduction function using the transistor.

[0187] The first charging unidirectional conductive portion 306 can realize unidirectional output of the transducer 1 (eg, the solar panel 101 ), thereby preventing reverse transmission of electric energy to the transducer.

[0188] In one implementation, please refer to Figure 5 The power supply assembly 3 further includes a second charging unidirectional conduction portion 307 and a third charging unidirectional conduction portion 308;

[0189] The input end of the second charging unidirectional conduction part 307 is connected to the output end of the first charging unidirectional conduction part 306, and the output end of the second charging unidirectional conduction part 307 is connected to the first end of the first energy storage module 201 and the input side of the power supply module; further, please refer to Figures 7 to 11 、 Figure 14 The second unidirectional charging conduction unit 307 may include at least one second charging diode D12. If at least two second charging diodes are included, the second charging diodes may be connected in series. In an example not shown, the second unidirectional charging conduction unit 307 includes at least one second charging transistor, thereby achieving the unidirectional conduction function using the transistor.

[0190] The input end of the third charging unidirectional conduction portion 308 is connected to the output end of the first charging unidirectional conduction portion 306, and the output end of the third charging unidirectional conduction portion 308 is connected to the first end of the second energy storage module 202 and the input side of the power supply module 304; For further information, please refer to Figures 7 to 11 、 Figure 14 The third unidirectional charging conduction unit 308 may include at least one third charging diode D13. If at least two third charging diodes are included, the third charging diodes may be connected in series. In an example not shown, the third unidirectional charging conduction unit 308 includes at least one third charging transistor, thereby achieving the unidirectional conduction function using the transistor.

[0191] The second charging unidirectional conduction portion and the third charging unidirectional conduction portion can realize unidirectional conduction during charging of the first energy storage module (eg capacitor C6) and the second energy storage module (eg capacitor C1), thereby avoiding discharge caused by reverse transfer of electric energy.

[0192] On this basis, if there is no third charging unidirectional conduction unit, the second energy storage module 202 will inevitably pass through the first energy storage module 201 when discharging. The specific process is as follows: the second energy storage module 202 discharges to the load, and when the current flows through the first energy storage module 201, the voltage of the first energy storage module 201 is charged to the same level as that of the second energy storage module 202. Then, the first energy storage module 201 and the second energy storage module 202 jointly discharge to the discharge module at the rear end. However, at night or in other usage environments, in order to maximize the power supply of the second energy storage module 202 to the load for a long time, so that the load can be used for a longer time in a dark environment, it is undesirable for the second energy storage module 202 to charge the first energy storage module 201 when discharging, because this will additionally increase the consumption of the second energy storage module 202. For this reason, the above solution introduces the third charging unidirectional conduction part. After the introduction of the third charging unidirectional conduction part, the current can only flow to the power-consuming module through the first energy storage module 201, and cannot flow in the opposite direction. Then, when the second energy storage module 202 is discharging, it can only supply power to the power-consuming module through the second on-off module 305 and the first discharging unidirectional conduction part (for example, the first discharging diode), without consuming electricity through the first energy storage module 201.

[0193] In one embodiment, in addition to the power supply of the transducer, other external power supplies can also be introduced. Please refer to Figure 5 、 Figures 7 to 11 The power supply assembly further includes a fourth charging unidirectional conduction portion 310, the input end of the fourth charging unidirectional conduction portion 310 is used to connect to an external power supply, and the output end of the fourth charging unidirectional conduction portion 310 is connected to the output end of the first charging unidirectional conduction portion 306. Figures 7 to 11 、 Figure 14 In the illustrated example, the fourth unidirectional charging conduction unit 310 includes at least one fourth charging diode D14. If at least two fourth charging diodes are included, the fourth charging diodes may be connected in series. In an example not shown, the fourth unidirectional charging conduction unit 310 may include at least one fourth charging transistor, thereby utilizing the transistor to achieve unidirectional conduction.

[0194] The external power supply may be understood as any other power supply other than the transducer, such as battery power supply, power supply from a power supply interface, etc.

[0195] In one implementation, please refer to Figure 5 The power supply assembly further includes a first discharge unidirectional conductive portion 311;

[0196] The input end of the first discharge unidirectional conduction part 311 is directly or indirectly connected to the first end of the second energy storage module 202, and the output end of the first discharge unidirectional conduction part 311 is connected to the input side of the power supply module. Figures 7 to 11 The first unidirectional discharge conducting portion includes at least one first discharge diode D21. If at least two first discharge diodes are included, the first discharge diodes may be connected in series. In an example not shown, the first unidirectional discharge conducting portion 311 may include at least one first discharge transistor, thereby achieving the unidirectional conduction function using the transistor.

[0197] The first discharging unidirectional conducting portion 311 can prevent the electric energy of the first energy storage module from being transmitted to the second energy storage module.

[0198] In one implementation, please refer to Figure 5 The power supply component 3 further includes a second discharge unidirectional conductive portion 312;

If at least two second discharge diodes are included, the second discharge diodes may be connected in series. In an example not shown, the second unidirectional discharge conducting portion 312 may include at least one second discharge transistor, thereby achieving the unidirectional conduction function using the transistor.

[0200] The second discharge unidirectional conduction portion 312 can prevent the electric energy output by the second energy storage module 202 when supplying energy to the power-consuming module 4 during the power supply phase from passing through the first energy storage module.

[0207] If the number of nodes is not limited to three, the corresponding connection states may also include but are not limited to the above two.

[0208] The state switching of the first switching unit 313 can be controlled by the power module 4 (e.g., its control unit 401), or can be controlled by other circuits or external signals. In one example, the control end of the first switching unit 313 is electrically connected to the power module 4 so as to be able to switch between two connection states under the control of the power module;

[0211] In the pre-powering stage, when the voltage on the input side of the power supply module 304 is lower than the specified voltage threshold, the first switching unit 313 is controlled to maintain the second state, so that the transducer only charges the first energy storage module 201 in the pre-powering stage.

[0217] The number of nodes of the second switching unit 314 may be three. In some examples, the number is not limited to three, for example, it may be four or more.

[0218] The second switching unit 314 has at least the following two connection states:

[0219] In a third state, the first node of the second switching unit is connected to the third node, so that the second end of the first energy storage module is grounded;

[0220] In the fourth state, the first node and the second node of the second switching unit are connected, so that the second end of the first energy storage module is electrically connected to the first end of the second energy storage module to form a series power supply circuit connection relationship.

[0221] If the number of nodes is not limited to three, the corresponding connection states may also include but are not limited to the above two.

[0222] The state switching of the first switching unit 313 can be controlled by the power module 4 (for example, its control unit 401), or can be controlled by other circuits or external signals. In one example, the control end of the second switching unit 314 is connected to the power module 4 (for example, its control unit 401) so as to be able to switch between two connection states under the control of the power module;

[0223] Wherein, the power consumption module is further configured to:

[0224] In the power supply phase, when the voltage on the input side of the power supply module 304 is higher than the specified threshold, the second switching unit is controlled to maintain the third state, so that the first energy storage module forms a parallel circuit relationship with the second energy storage module in the circuit;

[0225] When the voltage at the input side of the power supply module is lower than the specified voltage threshold, the second switching unit is controlled to maintain the fourth state, so that the first energy storage module forms a series circuit relationship with the second energy storage module in the circuit.

[0226] Among them, the specified threshold used when the first switching unit switches may be the same as the specified threshold used when the second switching unit switches, and the specified threshold used when the first switching unit switches may also be different from (for example, higher or lower than) the specified threshold used when the second switching unit switches.

[0227] In a specific example, the second switching unit 314 includes a third switch tube and a fourth switch tube; the third switch tube and the fourth switch tube can be referred to Figure 12 The transistor Qa and transistor Qb shown are understood;

[0228] The first end of the third switch tube is connected to the first end of the fourth switch tube to form a first node of the second switching unit, the second end of the third switch tube forms a second node of the third switching unit, and the second end of the fourth switch tube forms a third node of the second switching unit;

[0230] In one implementation, please refer to Figure 14 The first on-off module 301 includes a first on-off transistor Q1A and a first on-off driving tube Q2A;

[0231] The first end of the first on-off transistor Q1A is directly or indirectly connected to the first end of the transducer 1, and the second end of the first on-off transistor Q1A is directly or indirectly connected to the first end of the second energy storage module (for example, capacitor C1). Specifically, the second end of the first on-off transistor Q1A can be connected to and conducted to the second energy storage module (for example, capacitor C1) via the body diode of the second on-off transistor Q2A in the second on-off module 305, thereby charging the second energy storage module when it is turned on; the control end of the first on-off driving transistor Q2A serves as the first control end and is connected to the power consumption module (for example, the control unit 401 of the power consumption module 4) via a resistor. The first end of the first on-off driving transistor Q2A is connected to the control end of the first on-off transistor Q1A, and the second end of the first on-off driving transistor is grounded. In addition, the second end of the first on-off driving transistor Q2A is also connected to the output end of the energy storage detection module as the second control end.

[0232] The first on-off transistor Q1A may be a field effect transistor or a triode, and the first on-off driving transistor Q2A may be a field effect transistor or a triode.

[0233] For further information, please refer to Figure 14 , a second on-off module 305 connected between the first end of the second energy storage module 202 and the input side of the power supply module 304 includes a second on-off transistor Q1B;

[0234] A first end of the second on-off transistor Q1B is directly or indirectly connected to a first end of the second energy storage module, a second end of the second on-off transistor Q1B is connected to an input side of the power supply module 304, and a control end of the second on-off transistor Q1B is controlled by the power-consuming module 4 (e.g., its control unit 401) so as to be suitable for being switched on and off under the control of the power-consuming module 4.

[0235] The second on-off transistor Q1B may be a field effect transistor with a body diode.

[0236] The second end of the first on-off transistor Q1A is connected to the second energy storage module (e.g., capacitor C1) via the second on-off transistor Q1B, and is configured such that when the second on-off transistor Q1B is turned off and the first on-off transistor Q1A is turned on, the electric energy transmitted by the first on-off transistor Q1A can be delivered to the second energy storage module (e.g., capacitor C1) via the body diode of the second on-off transistor Q1B.

[0237] In a further embodiment, the second on-off module 305 further includes a second on-off driver transistor Q2B. The control end of the second on-off driver transistor Q2B is connected to the power-consuming module 4 (e.g., the control unit 401 of the power-consuming module 4) via a resistor. The first end of the second on-off driver transistor Q2B is connected to the control end of the second on-off transistor Q1B. The first end of the second on-off driver transistor Q2B is further connected to the first end of the second energy storage module (e.g., the capacitor C1) via a pull-up resistor. The second end of the second on-off driver transistor Q2B is grounded. A pull-down resistor R5 is provided between the second end and the control end of the second on-off driver transistor Q2B, so that the second on-off driver transistor Q2B is controlled to be turned on and off by the power-consuming module. When the second on-off driver transistor Q2B is turned on, the control end of the second on-off transistor Q1B is grounded and triggered.

[0238] The second on-off driving tube may be a triode or a field effect tube.

[0239] In addition, in some solutions, the first on-off transistor and the second on-off transistor may not be driven by a driver tube, and the first on-off transistor and the second on-off transistor are directly controlled by the power module 4 (such as the control unit 401). Figures 7 to 11 The power module 4 includes a control unit 401 ; the output side of the power supply module 304 is connected to the control unit 401 , and the first control end of the first on-off module 301 is controlled by the control unit 401 .

[0240] Furthermore, the power module 4 further includes a wireless unit 404; the wireless unit 404 is directly or indirectly connected to the control unit 401 to transmit a preset wireless signal under the control of the control unit 401. The wireless unit may include at least one of the following: a Bluetooth wireless unit, a radio frequency wireless unit, and a Wi-Fi wireless unit.

[0241] At the same time, the wireless unit 404 can also be directly or indirectly connected to the output side of the power supply module 304, thereby receiving power. Furthermore, the power consumption module 4 also includes a wireless on / off unit 403; the output side of the power supply module 304 is also connected to the power supply terminal of the wireless unit 404 via the wireless on / off unit 403. The control terminal of the wireless on / off unit 403 is connected to the control unit 401 and is configured to be controlled by the control unit 401 to switch the power supply module 304 and the power supply terminal of the wireless unit 404 on and off. Furthermore, the control unit 401 can control whether the wireless unit 404 is powered.

[0242] In a specific solution, the control unit 401 is configured to:

[0243] When it is necessary to use the wireless unit to send or receive a wireless signal, controlling the wireless on-off unit to be turned on;

[0244] When the wireless unit does not need to be used to send or receive wireless signals, the wireless on-off unit is controlled to be turned off.

[0245] By controlling the shutdown of the wireless on-off unit, the standby energy consumption of the wireless unit can be reduced.

[0246] In one implementation, please refer to Figure 21 , the wireless on-off unit 403 includes a wireless on-off field effect transistor Q0B;

[0247] The two ends of the wireless on-off field effect tube are respectively connected to the output side of the power supply module 304 and the power supply end of the wireless unit 404. The control end of the wireless on-off field effect tube Q0B is controlled by the control unit 401 so as to be turned on and off under the control of the control unit.

[0248] In one implementation, please refer to Figure 20 , the wireless on-off unit 403 includes a wireless on-off transistor Q0A;

[0249] The first end of the wireless on-off transistor Q0A is connected to the output side of the power supply module 304, the second end of the wireless on-off transistor Q0A is connected to the power supply end of the wireless unit 404, and the control end of the wireless on-off transistor Q0A is connected to the control unit 401 through a current limiting resistor R100 so as to be turned on and off under the control of the control unit 401.

[0250] In one implementation, please refer to Figure 19 The wireless on-off unit 403 includes a wireless on-off transistor Q3 and a wireless on-off driving tube Q4A; wherein the wireless on-off transistor Q3 can be a field effect tube or a triode, wherein the wireless on-off driving tube Q4A can be a field effect tube or a triode;

[0251] The two ends of the wireless on-off transistor Q3 are respectively connected to the output side of the power supply module 304 and the power supply end of the wireless unit 404, and the control end of the wireless on-off transistor Q3 is connected to the first end of the wireless on-off driving tube;

[0252] The control end of the wireless on-off driver Q4A is connected to the control unit 401 via a current-limiting resistor R13, the second end of the wireless on-off driver Q4A is grounded, and the first end of the wireless on-off driver Q4A is further connected to the output side of the power supply module 304 via a pull-up resistor R8; a resistor R16 is also connected between the second end and the control end of the wireless on-off driver Q4A.

[0253] For Figures 13 to 17 、 Figure 19 、 Figure 22 The circuit, its working process can be, for example:

[0254] The solar panel 101 charges the capacitor C6 of the first energy storage module through the diode in module D3A. The voltage MCUPW of capacitor C6 is input to the VDD of the power supply voltage detection chip 30421, which not only supplies power to the chip but also transmits the voltage signal of capacitor C6 to the power supply voltage detection chip 30421. When the power supply voltage detection chip 30421 detects that the voltage of capacitor C6 has reached the threshold Von (i.e., the first voltage threshold), it outputs an enable signal DCDCEN via the RESET pin to the EN pin of the power supply chip 30414 (which is a switching power supply or part of a switching power supply) in the power supply unit 3041. At the same time, the Vin pin of the power supply chip 30414 is connected to the MCUPW of capacitor C6. When the EN pin of the power supply chip 30414 is enabled, the power supply chip 30414 begins to operate, steps down the input voltage MCUPW, and outputs DVCC via the SW pin to power the power-consuming module 4.

[0255] The Von value (i.e., the first voltage threshold) must be greater than the minimum voltage required for the power-consuming module to operate. The voltage provided by Von should be sufficient to meet the power requirements for a series of initializations during startup. Because the components in the load are in an uncertain state before initialization, which consumes a lot of power, Von must be greater than the minimum voltage required for the load to operate smoothly to ensure successful startup and initialization. This significantly reduces power consumption after initialization. For example, if the minimum voltage required for the load to operate is 1.8V, Von (i.e., the first voltage threshold) can generally be set to 2.0V.

[0256] After the load is powered on, the MUC4011 of the control unit 401 is powered on, and the MUC4011 sends the sensing signal TR2_Ctr to the first on-off module 301 through the PC5 pin. At the same time, the energy storage detection module 303 (for example, the energy storage voltage detection chip 3031 therein) inputs the voltage signal PWLINE2 of the capacitor C1 of the second energy storage module through the VDD pin. When PWLINE2 is less than the threshold voltage Vc1 (i.e., the second voltage threshold) of the second capacitor C1, the energy storage voltage detection chip 3031 outputs a low level P through the RESET pin. WCHECK is connected to the emitter of the first on-off driver Q2A. At this time, TR2_Ctr is at a high level and PWCHECK is at a low level, so the first on-off driver Q2A is turned on, thereby turning on the first on-off transistor Q1A. The current of the solar panel 101 is divided into two paths. One path charges the first capacitor C6 through the diode in the module D3A, and the other path charges the capacitor C1 through the diode in the module D3A - resistor R14 - the first on-off transistor Q1A - the diode on the left of the module D3B - the diode in the second on-off transistor Q1B.

[0257] When the energy storage detection module detects that the second energy storage module 202 is full, the first on-off module is disconnected to prevent overcharging, specifically:

[0258] When PWLINE2 is greater than Vc1, the energy storage voltage detection chip 3031 outputs a high level through the RESET pin. At this time, PWCHECK is at a high level. Regardless of whether TR2_Ctr is at a high level or a low level, Q2A will be cut off. Then, the G pole of Q1A is pulled to a high level by R10 and R14, so that Q1A is cut off, that is, the first on-off module is turned off.

[0259] When the second energy storage module 202 needs to discharge (for example, at night), the MCU4011 of the control unit sends a high-level sensor signal TR1_Ctr to the base of the first on-off driver tube Q2B through the PC6 pin, so that the first on-off driver tube Q2B is turned on, and the gate of the first on-off transistor Q1B is grounded to turn on the first on-off transistor Q1B, that is, the second on-off module 305 is turned on. At this time, the capacitor C1 can output the voltage to the input end of the switching power supply through the diode on the right side of the first on-off transistor Q1B-module D3B, and then supply power to the load after conversion by the switching power supply.

[0260] When a wireless signal needs to be sent, MCU4011 sends a high-level sensing signal RFPWCtr to the base of the wireless on-off driver tube Q4A in the wireless on-off unit 403 through the PD0 pin, so that the wireless on-off driver tube Q4A is turned on, and then the gate of the wireless on-off transistor Q3 is grounded to turn on the wireless on-off transistor Q3. Then, DVCC can output RFDVCC to the wireless unit through the wireless on-off transistor Q3, so that the wireless unit is powered on and sends the preset signal.

[0261] In addition, pin 12 of MCU4011 in the control unit is connected to the positive pole of capacitor C1, which can be used to measure the power of capacitor C1, and then write the message required to be sent by the power module for user viewing.

[0262] In one implementation, please refer to Figures 7 to 11 、 Figure 25 , the power module 4 further includes a timing unit 406 , the timing unit 406 is connected to the power supply module 304 (eg, its power supply unit 3041 ) and / or the control unit 401 ;

[0263] The timing unit 406 is configured to stop the power supply module 304 to the control unit 401 when the control unit 401 is in sleep mode, and to start the power supply module 304 to the control unit 401 after a timing period, so that the control unit 401 is powered on or awakened on a timed basis.

[0264] In the above solution, by waking up (powering on) and stopping power supply at regular intervals, the control unit 401 can be powered off in a low power consumption state (such as sleep state) to reduce its energy consumption.

[0265] For further solutions, please refer to Figure 25 The timing unit 406 includes a timing on-off unit 4061 and a timing unit 4062. The timing on-off unit 4061 is provided between the control unit 401 and the output side of the power supply module 304. The timing unit 4062 is connected to the timing on-off unit 4061 to control the on-off of the timing on-off unit 4061. The timing unit can realize the timing function of the timing duration. After the timing on-off unit 4061 is turned off, the timing unit can start timing. When the timing reaches the timing duration, the timing on-off unit 4061 is turned on to start the power supply of the power supply module 304 to the control unit 401.

[0266] In a further embodiment, the timing unit can not only directly control the power supply between the power supply unit 3041 and the control unit, but also control whether the power supply unit is working. Furthermore, the timing unit 406 (for example, the timing part 4062 thereof) can also be connected to the trigger end of the power supply unit 3041 of the power supply module 304.

[0267] When the timing unit 406 stops the power supply module from supplying power to the control unit, it is specifically configured to:

[0268] Triggering the power supply unit 3041 to stop working;

[0269] When the timing unit starts the power supply module to the control unit, it is specifically used to:

[0270] The power supply unit 3041 is triggered to start working.

[0271] In which, when the power supply unit 3041 includes a conversion part, the timing unit 406 (for example, its timing part 4062) can be connected to the control end (or trigger end, enable end) of the conversion part to trigger the power supply unit 3041 to start and stop working, and then, for example, the conversion part can be triggered to start and stop working; when the power supply unit 3041 includes multiple conversion parts, the control end (or trigger end, enable end) of the conversion part can be connected to the timing unit 406 (for example, its timing part 4062), and the control unit 401 and / or the power supply detection unit 3042 respectively through logic gates.

[0272] In one implementation, please refer to Figure 22 、 Figures 26 to 30 , the power module 4 further includes an actuating portion (such as a button S2, a button KEY1, a button KEY2);

[0273] Please refer to Figure 22 、 Figures 26 to 30 The actuator (e.g., key S2, key KEY1, key KEY2) is configured to switch between on and off states in response to an external actuation being triggered. One end of the actuator is electrically connected to a port of the control unit 401 (e.g., MCU4011 in the control unit 401), and the other end is grounded. The end connected to the control unit 401 (e.g., MCU4011 in the control unit 401) is also connected to the output side of the power supply module 304 via a pull-up resistor (e.g., pull-up resistor R19, pull-up resistor R1, pull-up resistor R2), so that when the actuator is triggered and turned on, the corresponding port of the control unit 401 (e.g., MCU4011 in the control unit 401) detects a specified voltage level (e.g., a low voltage level). Furthermore, a filter capacitor (e.g., filter capacitor C26, filter capacitor Cf3, filter capacitor Cf4) is provided between the two ends of the actuator (e.g., key S2, key KEY1, key KEY2).

[0274] The actuating part may adopt a knob switch in addition to a push switch.

[0275] In some solutions, when the actuator is a push switch (i.e., a button), it may be necessary to use the actuator to perform corresponding operations (such as using a button to switch modes), where the operations include long press, short press, rapid multiple presses, etc. Figure 26 For example, each time you press the KEY key, the conduction will consume power, and then, Figure 26 The buttons shown will cause more power consumption.

[0276] To illustrate this problem, Figure 26 For example, when KEY1 is pressed, current will flow from DVCC through the pull-up resistor R1, KEY1, and to GND. If the key is pressed for a long time (that is, the key is not released after being pressed), the system will continue to consume the current of DVCC / R1. This current will be relatively large compared to the system standby current (for example, if DVCC = 3.3V and R1 = 10KΩ, it will result in a current consumption of 3.3mA, which cannot be ignored compared to the standby current of microamperes or even nanoamperes).

[0277] In some solutions, the current can be reduced by increasing the resistance of the pull-up resistor R1. However, the resistance of the pull-up resistor R1 cannot be too large, otherwise the voltage drop of the noise on the pull-up resistor R1 will be too large, causing inaccurate recognition by the control unit (such as the IO port of the MCU). As a result, the button's anti-interference ability is very weak and it is easy to be triggered by mistake.

[0278] exist Figures 27 to 29 ,as well as Figure 22In the example, a filter capacitor (such as filter capacitor C26, filter capacitor Cf3, and filter capacitor Cf4) can be added to improve stability; small voltage fluctuations such as accidental touch and interference can be buffered by the capacitor to prevent false triggering.

[0279] In a further improvement, a switch S5 can be introduced, and a pin of the control unit (such as its MCU) can be added (for example, pin 10a is added on the basis of pin 10b) to control the on and off of the switch S5, so as to cooperate with the program to reduce the current consumption when long pressing.

[0280] exist Figure 28 In the example shown, the switch S5 is located outside the MCU4011. Figure 29 In the example shown, the switch S5 can be provided in the MCU4011, wherein the control end of the switch S5 is connected to the MCU4011 (e.g., its pin 10a) or a controller therein, the first end of the switch S5 is connected to the output side of the power supply module, and the second end of the switch S5 is connected to one end of the key KEY1 (i.e., the key KEY1 is connected to one end of the MCU4011, e.g., its pin 10b) via a pull-up resistor.

[0281] Regardless of whether the switch S5 is located inside or outside the MCU, the control unit 401 (e.g., the MCU 4011 thereof) can be used to:

[0282] When switch S5 is turned on, it detects whether a key (such as key KEY1 or key KEY2) is pressed. If it is detected that the key is not pressed, switch S5 can be controlled to remain on. If it is detected that the key is pressed, switch S5 can be controlled to be turned off and timing can be started. When the timing reaches the specified time, switch S5 can be controlled to be turned on again and the above process can be repeated.

[0283] In the above process, the time when the key is pressed and the time when it is not pressed can be determined. Based on the time when the key is pressed and the time when it is not pressed, it can be determined whether a long press, continuous click, or single click occurs.

[0284] In the above scheme, the switch is controlled to be turned off when the button is detected. At this time, a loop can be avoided between DVCC, the pull-up resistor, the button, and the ground, thereby effectively reducing energy consumption and achieving the purpose of saving power.

[0285] In a specific example, Figure 28 For example, the MCU can perform the following process:

[0286] X1: The MCU can first set pin IOb to input to detect whether the key KEY1 is pressed; set pin IOa to output high level to turn on switch S5 and power the key circuit;

[0287] X2: MCU can start sleep mode and start falling edge detection;

[0288] X3: When pin 10b detects the falling edge of the key KEY1 being pressed, the MCU can be controlled to output a low level on both pins 10a and 10b, closing switch S5 and shutting off the power supply circuit. This prevents a loop from forming between DVCC, the pull-up resistor, the key, and the ground, which would cause power consumption.

[0289] X4: The MCU starts to sleep and wakes up at a specified time. After the specified timer duration is reached, the MCU can set pin IOb to input to detect the current state of key KEY1; pin IO2 is set to output high level to turn on switch S5 to power the key circuit;

[0290] X5: If pin IO1 detects a low level, it means that the key KEY1 is still in the pressed state, and you can return to step X3. Otherwise, it means that the key is no longer pressed (i.e., it rebounds); based on this, the number of consecutive presses or the continuous pressing time of the key can be calculated.

[0291] exist Figure 29 In the example shown, its working process can be understood by referring to the above description.

[0292] In one implementation, please refer to Figure 30 The power module 4 further includes an indication unit 402 , which is connected to a port of the control unit 401 to emit light under the control of the control unit.

[0293] The indicator unit 402 may emit light to indicate one or more types of information, such as the operating status of the power module, a change in the operating mode of the power module, or whether or not the power module has issued a signal. Regardless of the type of information indicated by the indicator unit 402, the information does not depart from the scope of the embodiments of the present invention.

[0294] For further examples, see Figure 30 The indicating unit 402 includes an indicating transistor Q4B and a light emitting diode LED1; the indicating transistor Q4B can be a triode as shown in the figure, or can be a field effect transistor.

[0295] The cathode of the light-emitting diode LED1 is connected to the first end of the indicator transistor Q4B, the second end of the indicator transistor Q4B is grounded, the control end of the indicator transistor Q4B is connected to the control unit 401 via the resistor R21, and the anode of the light-emitting diode LED1 is connected to the corresponding voltage source via the resistor R17.

[0296] The light emitting diode may be a blue light emitting diode, and the possibility of it being other colors is not excluded. The voltage source is the input side of the power supply module.

[0297] The blue LED requires a voltage of at least 2V to light up, so resistor R17 is connected to MCUPW instead of DVCC (in the specific example, DVCC may only be 1.8V, which is not enough to light up the LED1). That is, the voltage input to LED1 is not stepped down by the power supply module to ensure that the bulb is lit.

[0298] In one embodiment, the power supply circuit further includes an external power supply interface, which can be connected to an external power supply; the external power supply interface is directly or indirectly connected to the first end of the first energy storage module and the first end of the second energy storage module, and is used to power the first energy storage module and the second energy storage module through an external power supply, thereby starting the power-consuming module.

[0299] In one embodiment, the power module 4 can be connected to the sensor 5. Furthermore, an embodiment of the present invention can provide a sensing device, which includes the power supply circuit mentioned above and at least one sensor 5, wherein the power module 4 can serve as a part of the power supply circuit or as a circuit module connected to the power supply circuit.

[0300] The sensor 5 is configured to generate a sensing signal in response to a detection result of an external detection;

[0301] The power consumption module may be powered during the power supply phase, and then transmit a wireless signal (which may be sent by a wireless unit) to receive the sensing signal. The wireless signal may include, for example, a status update message that can represent the detection result.

[0302] In one embodiment, the sensor may be a sensor for detecting whether a door or window is open, such as a door magnetic sensor.

[0303] In one embodiment, the sensor includes a state switching unit S1 ; the state switching unit S1 is connected to the control unit 401 .

[0304] The state switching unit S1 is configured to switch states in response to changes in a magnetic field associated with a detection result, wherein when the state switching unit is in different states, different sensing signals are generated and sent to the control unit.

[0305] The magnetic field change can, for example, occur when a desired detection result is achieved in the detected object or environment (e.g., a door or window being open or closed). Any of the following can occur: forming a magnetic field, removing a magnetic field, changing the direction of the magnetic field, changing the intensity of the magnetic field, etc. Regardless of how the magnetic field changes, as long as it causes a state change in the state switching unit (e.g., changing the node connected in the state switching unit S1), it falls within the scope of the above description.

[0306] For the state switching part with three nodes, a single-pole double-throw magnetic switch (such as a single-pole double-throw reed switch) can be used. The position of the magnet changes with the change of the detection result. For example, it can have two different states. Based on this, a series of state recognition is realized. The specific states can be shown in the figure below:

[0307] Serial number state 1 ON 2 ON->OFF 3 OFF 4 OF->ON

[0308] In addition, the state switching unit S1 may not be magnetically controlled, for example, it may be implemented by a mechanical switch. Compared with a mechanical switch, a magnetically controlled switch consumes no current and has almost no static power consumption.

[0309] For a specific solution, please refer to Figures 22 to 24 , the state switching unit S1 has at least three nodes, and the at least three nodes include at least one feedback node and a ground node;

[0310] The feedback node is directly or indirectly connected to the control unit 401, and the ground node is directly or indirectly connected to the ground; Figure 22 In the example shown, there is only one feedback node. Figure 23 、 Figure 25 In the example shown, the number of feedback nodes is two.

[0311] The state switching unit S1 is used to:

[0312] In response to the detection result of the external detection, the on-off relationship between the at least three nodes is changed; wherein different detection results correspond to different on-off relationships, thereby generating different sensing signals, so that the control unit obtains the detection result.

[0313] by Figure 22 For example, the number of the feedback node is one; the at least three nodes further include a power supply node, which is connected to the output side of the power supply module to access the DVCC;

[0314] The state switching unit (such as the single-pole double-throw switch S1) is used to:

[0315] When the detection result is a first detection result (for example, a door or window is open), connecting the feedback node and the power supply node to generate a sensing signal;

[0316] When the detection result is a second detection result (for example, the door or window is closed or not opened), the feedback node and the ground node are connected to generate another sensing signal.

[0317] In addition, Figure 22 In the example shown, the sensor 5 further includes a sensor capacitor C25 , and the feedback node is further grounded via the sensor capacitor C25 to filter the signal transmitted by the feedback node.

[0318] by Figure 22 For example, the sensor's single-pole double-throw switch S1 uses a magnetically controlled switch. When nodes 1 and 2 are connected, the switch is in one state (for example, a door is closed), and when nodes 1 and 3 are connected, the switch is in another state (door is open). For example, if the switch S1 is in the state of connecting nodes 1 and 2, and this state remains for a long time, the path from DVCC to resistor R18 to the single-pole double-throw switch S1 to the MCU will remain connected, causing resistor R18 to continuously consume power. If the switch S1 switches from connecting node 1 to node 2 to connecting node 1 to node 3 and this state remains for a long time, the path from MCU to the single-pole double-throw switch S1 to resistor R27 to GND will remain connected, causing resistor R27 to continuously consume power, resulting in increased power consumption.

[0319] It can be seen that the above solutions will cause the problem of high power consumption. Figure 23 、 Figure 24 The solution can help reduce power consumption. Figure 23 、 Figure 24 For example, there are two feedback nodes, namely a first feedback node and a second feedback node; the two feedback nodes are respectively connected to different ports of the control unit 401 (for example, its MCU 4011); the voltage of the first feedback node or the second feedback node can be pulled to match the voltage of the output side of the power supply module (for example, pulled to DVCC, or pulled to DVCC through a resistor);

[0320] The state switching unit (such as the single-pole double-throw switch S1) is used to:

[0321] When the detection result is a first detection result, connecting the first feedback node and the ground node to generate a sensing signal;

[0322] When the detection result is a second detection result, the second feedback node and the ground node are connected to generate another sensing signal.

[0323] In a further example, the first feedback node is connected to a first feedback switch S3, and the second feedback node is connected to a second feedback switch S4;

[0324] The control unit is further configured to:

[0325] After the ground node changes from a state of being connected to the second feedback node to a state of being connected to the first feedback node, controlling the first feedback switch to be turned off and controlling the second feedback switch to be turned on, so that: the control unit can detect whether the ground node is connected to the second feedback node;

[0326] After the ground node changes from a state of being connected to the first feedback node to a state of being connected to the second feedback node, the second feedback switch is controlled to be turned off, and the first feedback switch is controlled to be turned on, so that the control unit can detect whether the ground node is connected to the first feedback node.

[0327] The first feedback switch S3 and the second feedback switch S4 can be externally connected to the MCU 4011 or built into the MCU 4011 .

[0328] in, Figure 23 and Figure 24 The principle is similar, the difference can be understood as follows: Figure 24 The MCU internal switch and pull-up resistor are used. Figure 23 In this case, a switch and a pull-up resistor are set outside the MCU.

[0329] by Figure 23 For example, the state detection process of the magnetic switch in the sensor for detecting the door switch state can be as follows:

[0330] The MCU sets pins IO1 and IO4 as inputs to detect the status of the magnetically controlled switch (i.e., single-pole double-throw switch S1). Pins IO2 and IO3 both output high levels to turn on the first feedback switch S3 and the second feedback switch S4.

[0331] If the level of pin IO4 changes from high to low, it means that S1 1 and 2 are connected (this state is defined as the door open state). If the door is always open, the current will be continuously consumed through the path of DVCC-resistor R18-second feedback switch S4-single-pole double-throw switch S1-GND, resulting in power waste.

[0332] Since the door is in the open state, the next state is definitely closed (the door is either open or closed), so it is meaningless to continue to monitor pin IO4 at this time. Therefore, pin IO3 outputs a low level, disconnecting the second feedback switch S4, and thus disconnecting the path from DVCC to resistor R18 to the second feedback switch S4 to S1 to GND, preventing continued power consumption. At the same time, IO1 is set to an input, and IO2 outputs a high level, turning on the first feedback switch S3, and detecting the door closed state through pin IO1.

[0333] When the level of pin IO1 changes from high to low, nodes 1 and 3 of the single-pole double-throw switch S1 are connected, indicating that the door state has changed from open to closed. At this time, if the door has been closed, the current will continue to be consumed through the path of DVCC-resistor R27-first feedback switch S3-single-pole double-throw switch S1-GND, resulting in power waste.

[0334] Since the next state after the door is closed is definitely the door opening, it is meaningless to detect pin IO1 at this time. Therefore, pin IO2 outputs a low level at this time, closing the first feedback switch S3, cutting off the path and preventing power consumption. At the same time, pin IO4 is set to input, pin IO3 outputs a high level, turning on the second feedback switch S4, and detecting the arrival of the door opening state through pin IO4.

[0335] This cycle repeats itself.

[0336] by Figure 24 For example, the state detection process of the magnetic switch in the sensor for detecting the door switch state can be as follows:

[0337] Pins IO1 and IO2 are both set to input detection;

[0338] If pin IO2 detects a falling edge (or low level), it means that nodes 1 and 2 in the single-pole double-throw switch S1 are connected (gate closed state); if the gate is always closed, the current will continue to be consumed through the path of pin IO2-single-pole double-throw switch S1-GND;

[0339] MCU4011 disconnects pin IO2, or makes pin IO2 output high impedance state and disconnects the path from IO2 to single-pole double-throw switch S1 to GND to prevent power consumption; at the same time, pin IO1 is set to input detection to detect the arrival of the door opening state through pin IO1;

[0340] When pin IO1 detects a falling edge (or low level), it means that nodes 1 and 3 in the single-pole double-throw switch S1 are connected (door open state). If the door is always open, the current will continue to be consumed through the path of node IO1-single-pole double-throw switch S1-GND.

[0341] MCU4011 disconnects pin IO1, or makes pin IO1 output high impedance state and disconnects pin IO1-single-pole double-throw switch S1-GND to prevent power consumption; at the same time, pin IO2 is set to input detection to detect the arrival of the door closed state through pin IO2;

[0342] This cycle repeats itself.

[0343] In other examples not shown, the state switching portion may have only two nodes. Furthermore, one node is connected to the control unit, and the other node being suspended, short-circuited, pulled up, or pulled down may generate corresponding sensing signals.

[0344] Please refer to Figure 31 The sensor may be, for example, a Hall sensor 501, which may have an input terminal, an output terminal, and a ground terminal. The input terminal may be grounded via an input capacitor Cin, and the output terminal may be connected to a control unit. The voltage input to the input terminal may be, for example, DVCC.

[0345] For further examples, see Figure 32 The Hall sensor 501 may include: a clock control unit 5011, a Hall disk 5012, an offset voltage suppression unit 5013, an amplifier 5014, a comparator 5015, a logic output unit 5016, an upper tube Q51 and a lower tube Q52;

[0346] The Hall effect sensor 5012 can output an electrical signal in response to a magnetic field or changes therein. The output side of the Hall effect sensor 5012 is connected to an offset voltage suppression unit 5013, which suppresses the offset voltage of the output signal of the Hall effect sensor 5012. An amplifier 5014 then amplifies the suppressed electrical signal, which represents information about the detected magnetic field. A comparator 5015 compares the amplified signal with a reference signal and feeds the comparison result back to a logic output unit 5016. The logic output unit 5016 can control the on / off state of the upper tube Q51 or the lower tube Q52. When the upper tube Q51 is on, the lower tube Q52 is simultaneously turned off. When the lower tube Q52 is on, the upper tube Q51 is simultaneously turned off. The output of the Hall effect sensor can be connected between the upper tube Q51 and the lower tube Q52, so that when the upper tube Q51 is on, it sends a high level to the control unit, and when the lower tube Q52 is on, it sends a low level to the notification unit. The clock control unit 5011 can be connected to the offset voltage suppression unit 5013, the amplifier 5014, the comparator 5015, and the logic output unit 5016, respectively. Furthermore, the clock control unit 5011 can output a clock signal to control the wakeup and sleep states of the offset voltage suppression unit 5013, the amplifier 5014, the comparator 5015, and the logic output unit 5016. In some embodiments, the clock control unit 5011 can also provide power to these units. The clock control unit 5011 can operate when receiving DVCC at its input.

[0347] The Hall sensor may be, for example, a KTH1601 Hall sensor or a KTH1901 Hall sensor.

[0348] In addition, the sensor may also include a TMR sensor, for example, the input end of the TMR sensor is connected to DVCC (i.e., the voltage at the VDD end), and the output end of the TMR sensor can be connected to the control unit. At the same time, the input end of the TMR sensor can be grounded via capacitor C29, and the output end can be grounded via capacitor C25.

[0349] In addition to the above, when the energy storage component supplies power to the power-consuming module, if the power supply to the power-consuming module is controlled solely based on the supply voltage range and the non-supply voltage range (i.e., the first voltage threshold), problems may arise. For example, if the back-end circuit (e.g., the power-consuming module) is powered on and begins operating after exceeding the first voltage threshold, but once the back-end circuit (e.g., the power-consuming module) is operating, the voltage is pulled below the first voltage threshold. At this point, the output will be shut down again (i.e., the power-consuming module will no longer be supplied). Consequently, the system may be in a continuous power-on / power-off cycle. If the problem is solved by simply raising the first voltage threshold, the "unusable voltage range" will be reduced.

[0350] To solve this problem, in one embodiment, the power supply component is further configured to be adapted to, when the power-consuming module is in a powered-on state and the output voltage of the energy storage component is within the power supply voltage range, enable the energy storage component to supply power to the power-consuming module; and, when the output voltage is within the non-power supply voltage range, enable the energy storage component to stop supplying power to the power-consuming module.

[0351] The supply voltage interval partially overlaps with the specified voltage interval.

[0352] For example, the designated voltage interval refers to an interval smaller than a first voltage threshold; the power supply voltage interval refers to an interval larger than a power supply stop threshold, and the first voltage threshold is higher than the power supply stop threshold.

[0353] The first voltage threshold can be, for example, 1.8V, and the power supply stop threshold can be, for example, 1.7V. When the output voltage of the energy storage component rises from low to high, it needs to be higher than the first voltage threshold (for example, 1.8V) to start the power supply to the power-consuming module and start the power-consuming module; when the output voltage of the energy storage component goes from high to low, it needs to be lower than the power supply stop threshold (for example, 1.7V) to turn off the output, that is, stop supplying power to the power-consuming module. This process can be, for example, Figure 33 shown.

[0354] exist Figure 33In the figure, V+ can be understood as the first voltage threshold, and V- can be understood as the power supply cut-off threshold. The thin line at the top of the figure can be understood as the input voltage of the power supply unit, that is, the output voltage of the energy storage component, and the thick line is the output voltage of the power supply unit.

[0355] The above process can be implemented using a power supply unit and a power supply detection unit, for example:

[0356] The power supply detection unit can detect the input side voltage of the power supply unit (i.e., the output voltage of the energy storage component). Before the power consumption module is powered on and the first energy storage module starts to be charged by the transducer, when the output voltage of the energy storage component increases but does not fall below the first voltage threshold, the power supply unit is not enabled (i.e., the power supply path between the energy storage component and the power consumption module is not connected). When the output voltage rises to the first voltage threshold, the power supply unit is enabled, the power supply between the energy storage component and the power consumption module is connected, and the power consumption module is powered on. After the power consumption module is powered on, the power supply detection unit (or other circuit, which can be, for example, a control unit or other detection unit, but is not limited thereto) can detect the input side voltage of the power supply unit (i.e., the output voltage of the energy storage component) to determine whether the output voltage of the energy storage component drops and reaches the power supply stop threshold (at this time, even if it drops to the first voltage threshold, the power supply unit will not stop supplying power). If the power supply stop threshold is reached, the power supply detection unit (or other circuit) can control the power supply unit to stop supplying power (for example, shut down).

[0357] In one example, the power supply detection unit (such as the detection chip therein) can be configured with a "hysteresis" output function, so there is no need to use a controller for software control; and different voltage detection chips have different hysteresis voltage values. For example, the voltage detection chip used can be selected with a hysteresis of 100mv (1.8V-1.7V), or detection chips with different voltage hysteresis values ​​can be selected according to actual needs.

[0358] It can be seen that the above solution avoids or reduces the possibility of the circuit being in a continuous power-on / power-off cycle.

[0359] In order to avoid or reduce the power-on / power-off cycle, this can also be achieved by corresponding settings of the power-consuming module. In one embodiment, the power-consuming module (e.g., its control unit) is configured so that: after power-on and when a specified condition is not satisfied, the power consumption of the power-consuming module is a first power consumption; after power-on and when the specified condition is satisfied, the power consumption of the power-consuming module is a second power consumption, and the first power consumption is lower than the second power consumption.

[0360] The specified conditions include at least one of the following:

[0361] The time elapsed after power-on exceeds the specified delay period;

[0362] The voltage of the first energy storage module exceeds a specified power consumption state switching threshold.

[0363] Specifically, the first power consumption is adapted to the power consumption of the power module when the wireless unit does not transmit the wireless signal, and the second power consumption is adapted to the power consumption of the power module when the wireless unit transmits the wireless signal.

[0364] Furthermore, the power consumption module also includes a sensor connected to the control unit, the first power consumption is adapted to the power consumption of the power consumption module when the sensor is not working and the wireless unit does not transmit the wireless signal, and the second power consumption is adapted to the power consumption of the power consumption module when the sensor is working and the wireless unit transmits the wireless signal.

[0365] In the above scheme, if the specified condition is that the time elapsed after power-on exceeds the specified delay period, then:

[0366] After the output voltage of the energy storage component reaches the first threshold, the power module is started, but is in the first working state (which can be understood as being in the working state of the first power consumption). For example, high-power-consuming actions may not be performed (the high-power-consuming actions may be, for example, packet sending). At this time, only the countdown after initialization may be performed, but the second working state (which can be understood as being in the working state of the second power consumption) may be entered after a delay of a preset time (i.e., a specified delay period), and then sensor detection and message sending may be performed.

[0367] In the above solution, if the specified condition is that the voltage of the first energy storage module exceeds a specified power consumption state switching threshold, then:

[0368] After the output voltage of the energy storage component reaches the first voltage threshold, the power-consuming module starts up but remains in the first operating state (which can be understood as the first power consumption operating state). For example, high-power consumption actions (such as packet sending) may not be executed. At this time, the capacitor voltage (such as the voltage of the first energy storage module) can be used to determine whether to enter the second operating state (which can be understood as the second power consumption operating state). After entering the second operating state, sensor detection and message sending can be performed. If the voltage of the first energy storage module is higher than the power consumption state switching threshold, the second operating state can be entered; if it is lower than the second power consumption state switching threshold, the first operating state is maintained.

[0369] In some schemes, in transport mode, Figure 13For example, when the control unit 401 (e.g., MCU 4011) is not powered on, one pin is connected to a voltage VSC2.8 via a resistor R15. Voltage VSC2.8 is the voltage of the second energy storage module, and voltage VSC2.8 leaks to the control unit 401 through the resistor R15. In normal operating mode, when the control unit is powered on and the second energy storage module supplies power to the large capacitor, DVCC will be pulled high, causing the entire supply voltage to be high.

[0370] Therefore, in Figure 37 In the circuit shown, a transistor can be used to measure the voltage of the second energy storage module (such as a large capacitor), thereby giving up Figure 13 The resistor R15 in Figure 37 In the circuit shown, the control unit can detect the voltage of the second energy storage module (eg, large capacitor) via the sampling module shown as 37 , wherein the voltage VSC2.8 is the voltage of the second energy storage module (eg, large capacitor).

[0371] For specific examples, please refer to Figure 37 The acquisition module may include: a transistor Q5B and a driving transistor Q6B. The first end of the driving transistor Q6B is connected to the gate of the transistor Q5B. A resistor R41 is provided between the first end and the gate of the transistor Q5B. The first end of the transistor Q5B can be connected to the second energy storage module to collect the voltage of the second energy storage module. The second end of the transistor Q5B is grounded via a resistor R42 and a resistor R43. Furthermore, the resistors R42 and R43 can achieve voltage division to form a voltage VBAIN, which can be input to the control unit to represent the voltage of the second energy storage module. The control unit of the power consumption module is connected between the resistors R42 and R43. The control end of the driving transistor Q6B is grounded via a resistor R45. The control end of the driving transistor Q6B is also connected to the control unit via a resistor R44 to receive a control signal.

[0372] Through this control signal, the driving tube Q6B can be controlled to be turned on when measurement is required. The control unit measures the voltage of the second energy storage module (e.g., a large capacitor) after being divided by the resistors R42 and R43 to obtain the voltage of the second energy storage module (e.g., a large capacitor).

[0373] Figure 37 The AD_Ctr1 pin can be connected to a control unit (such as an MCU) to control the on / off of the driver Q6B, and the VBAIN pin is connected to a control unit (such as an MCU) to obtain the voltage of the first energy storage module (such as a large capacitor).

[0374] In shipping mode, driver transistor Q6B and transistor Q5B are turned off to prevent leakage. When measuring the voltage of the second energy storage module (e.g., a large capacitor), the voltage divider resistors (i.e., resistors R42 and R43) ensure that VBAIN does not exceed the DC-DC output voltage VDD (1.8V). Furthermore, measuring the voltage of the second energy storage module (e.g., a large capacitor) can also be used to obtain the voltage value of the large capacitor and display it to the user.

[0375] Correspondingly, in the control unit, pin 18 of MCU4011 can be connected to DVCC via resistor R28, pin 19 can be connected to DVCC via resistor R29, pin 12 can be connected to the second energy storage module, and pin 11 can be connected to the first energy storage module. In transport mode, the discharge circuit of the first energy storage module and / or the second energy storage module can also be disconnected. For example, the second on-off module and the power supply unit can be disconnected to reduce power consumption during long-term storage / transport. To reduce startup conditions (under specific circumstances), if the second energy storage module (e.g., a large capacitor) is charged, the discharge circuit can be opened after startup (e.g., the second on-off module 305 is turned on). The second energy storage module (e.g., a large capacitor) can quickly charge the capacitor of the first energy storage module (e.g., a small capacitor) to the voltage of the second energy storage module and the voltage drop of the corresponding diode (the diode is connected between the first and second energy storage modules, such as the first discharge diode D21).

[0376] The embodiment of the present invention further provides a control method, which is applied to a power supply circuit, wherein the power supply circuit is used to provide power to a power module; Figure 40 , the control method includes:

[0421] The first mode can be understood as the normal working mode of the sensing device (or understood as including the power module and the sensor). In this mode, the status update of the status update message mentioned above can be realized. In some schemes, heartbeat messages can also be sent and received regularly in the normal working mode to ensure that the connection between the sensing device (or understood as including the power module and the sensor) and the server is maintained.

[0422] Furthermore, the control method further includes:

[0423] When in the first mode and the detection result has not changed, if the control unit is in sleep for a preset timer duration, the control unit is awakened once, and after each awakening, a heartbeat message is sent to the outside, and the control unit goes into sleep again after sending the heartbeat message. In one embodiment, the control method further includes:

[0424] When in the second mode, the second on-off module between the first end of the second energy storage module and the input side of the power supply module is controlled to remain off.

[0425] Battery products (such as sensor devices) consume power during transport and storage due to dormancy. Sensor devices, powered by solar panels in addition to batteries, can be powered by the panels. During transport and storage, the battery power can be disconnected to conserve battery life. Furthermore, sensor devices (or devices comprising power modules and sensors) can also have a storage mode as a secondary mode, in addition to normal operation.

[0426] During storage or transportation, the control unit can control the second on-off module 305 to be in the off state when in the second mode, thereby ensuring that the main power supply does not run out of power during transportation and long-term storage, causing the problem of failure to start. Furthermore, the control method also includes:

[0427] When in the first mode, if a first conversion signal is obtained, determining that the sensing device enters the second mode;

[0428] When in the second mode, if a second conversion signal is obtained, it is determined that the sensing device enters the first mode.

[0429] Optionally, the power consumption module further includes a button connected to the control unit, the first conversion signal is generated in response to a first manipulation of the button, and the second conversion signal is generated in response to a second manipulation of the button.

[0430] Optionally, the first manipulation is different from the second manipulation in at least one of the following aspects:

[0431] The key that was pressed;

[0432] The number of times the key was pressed;

[0433] The length of time the key was pressed.

[0434] Optionally, the first manipulation is that the button is pressed and held for a first specified time period;

[0435] The second manipulation is that the button is pressed a specified number of times, and the interval between two adjacent presses is less than a second specified time length.

[0436] Through the above solution, switching between two modes (i.e., switching between the first mode and the second mode, that is, switching between the normal working mode and the storage mode) can be achieved. The key can be, for example, key KEY1, key KEY2, key S2, that is, an actuator.

[0437] Optionally, after determining that the sensing device enters the first mode, the method further includes: sending a corresponding first mode message externally;

[0438] After determining that the sensor device enters the second mode, the method further includes: sending a corresponding second mode message to the outside.

[0439] Optionally, the power module further includes an indication unit; the indication unit may be, for example Figure 30 The indicating unit 402 is shown.

[0440] After determining that the power module enters the first mode, the method further includes: controlling the indicator unit to emit light to feed back a first feedback signal;

[0441] After determining that the power module enters the second mode, the method further includes: controlling the indicator unit to emit light to feed back a second feedback signal.

[0442] Optionally, at least one of the following aspects of the first feedback signal and the second feedback signal is different:

[0443] Number of times of luminescence;

[0444] Luminous duration;

[0445] Emitting color.

[0446] Optionally, the first feedback signal emits light N times, and the second feedback signal emits light M times, where M is not equal to N.

[0447] It can be seen that the above scheme can realize external feedback of the model.

[0448] Optionally, determining that the sensing device has entered the first mode includes: setting a mode identifier of the sensing device to a first mode identifier corresponding to the first mode, so as to indicate that the power module is in the first mode using the first mode identifier;

[0449] Determining that the sensing device enters the second mode includes: setting the mode identifier of the sensing device to a second mode identifier corresponding to the second mode, so as to use the second mode identifier to indicate that the power module is in the second mode.

[0450] If the sensor is a door or window sensor, then after a certain period of exposure to sunlight, the solar panel can quickly activate the power module through the first energy storage module, activating the sensor connected to the power module. This means that a certain amount of sunlight can be enough to power on the device. Therefore, simply disconnecting the second on / off module 305 can lead to the problem of accidental power-on due to sunlight exposure (for example, during transportation or handling, the solar panel may be accidentally exposed to sunlight, causing it to automatically power on).

[0451] To this end, a mode flag (i.e., a mode identifier) ​​can be stored in the control unit. This flag indicates whether the second energy storage module will be connected at the next startup. This means that after entering storage mode, additional triggering conditions are required to trigger the second energy storage module to connect. This ensures that the system does not accidentally trigger the second energy storage module to connect and consume power. In non-storage mode, this flag can be used to indicate system startup. This means that the system can automatically start up without external intervention as long as the startup conditions are met.

[0452] In the example of actual control process:

[0453] In normal working mode, press and hold the button for 3 seconds (this button can be used for example Figure 22 If the key S2 in the display is pressed, the control unit sends a mode switching message (e.g., a second mode message) via the wireless unit, and the light-emitting diode LED1 in the indicator unit 402 flashes three times before entering storage mode (i.e., the second mode). In storage mode (i.e., the second mode), the control unit instructs the second on-off module to disconnect, thereby disconnecting the discharge circuit of the second energy storage module (e.g., capacitor C1), and sets the mode flag in the memory to 1, indicating that the current mode is storage mode (i.e., the second mode). After entering storage mode (i.e., the second mode), if there is no continuous light, the energy in the first energy storage module will quickly run out, causing the system to lose power and notify work, allowing transportation or storage.

[0454] In storage mode, even if the solar panel accidentally receives light and activates the sensor, when the control unit is powered on and detects that the mode identifier is 1, it will still disconnect the second on-off module, so that the discharge circuit of the lithium battery (such as the second energy storage module) is disconnected, and the first energy storage module will stop working soon after the energy in the first energy storage module is consumed.

[0455] If you short-press the button three times in succession (with an interval of less than 1 second), a mode switching message (for example, the first mode message) is sent, the light-emitting diode LED1 flashes once, and the control unit sets the mode flag to 0, indicating that the normal working mode has been entered from the storage mode. This enables the sending of heartbeat messages and sensor detection.

[0456] In response to the above-mentioned scheme for switching between the first mode and the second mode, an embodiment of the present invention further provides a control method for a sensor device, the relevant description of which can be understood by referring to the description of the control method, power supply circuit, sensor device and other embodiments above; the sensor device includes a sensor and a power module, the power module includes a control unit, and the sensor is configured to detect a detection result externally;

For example, if the energy storage assembly includes the first and second energy storage modules mentioned above, then in the second mode, when the power-consuming module is powered, it can only be powered by the first energy storage module. In other examples, if there are three or more energy storage modules, in the second mode, the power-consuming module may be powered by only one energy storage module or by two or more energy storage modules.
