[0053] The following will refer to the appendices in the embodiments of this application. Figure 1 To be continued Figure 20 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0054] This application provides a passive electronic device that utilizes the principle of microwave spatial scattering and follows the law of energy conservation. It identifies and effectively captures weak nano-ampere electromagnetic wave signals wirelessly scattered into the air from various sources, extracting micro-energy. Through acquisition and energy storage algorithm chips, these micro-energy signals are precisely compared and calculated, then stored in an energy storage medium. All micro-energy within each processing unit can be effectively stored, accumulating over time to form a large energy pool. This pool provides continuous power to various intelligent node terminal devices operating at extremely low power consumption, enabling truly battery-free and maintenance-free adaptive intelligent operation for various IoT devices. It is understood that the passive electronic device in this application can be an electronic tag device, or, but is not limited to, a passive lock, a passive umbrella, etc. This application does not limit the specific structure or form of the passive electronic device.

[0055] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a first structure of the passive electronic device 100 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a first application scenario of the passive electronic device 100. The passive electronic device 100 may include a wireless receiving module 110, a power management module 120, and a load module 130.

[0056] The wireless receiver module 110 can receive wireless signals in space and convert them into micro-current signals (or electrical energy signals). Under the action of this micro-current signal (or electrical energy signal), the wireless receiver module 110 can be activated again and continue to receive wireless signals in space. Thus, the wireless receiver module 110 can form an effective positive feedback mechanism, enabling the entire wireless receiver module 110 to complete micro-energy harvesting without battery or power supply excitation. For example, as... Figure 2 As shown, various types of radio electromagnetic waves may be scattered around us in our daily living spaces, such as, but not limited to, Wireless Fidelity (Wi-Fi) signals in homes, Bluetooth Low Energy (BLE) signals around shared bicycles, and 3G, 4G, and 5G signals from communication base stations. These wireless signals of different frequencies can operate in the same space in real time. The wireless receiving module 110 of this application embodiment can receive wireless signals in the space and convert these electromagnetic wave wireless signals into micro-current signals or electrical energy signals in the form of current. The micro-current signal can be a nanoampere-level micro-current signal. The electrical energy signal or micro-current signal converted by the wireless receiving module 110 can be used for the operation of the wireless receiving module 110 itself, and excess electrical energy signals or micro-current signals can be transmitted to the power management module 120 for management.

[0057] The power management module 120 can be directly or indirectly electrically connected to the wireless receiving module 110 to receive micro-current signals or power signals transmitted by the wireless receiving module 110. This electrical connection can be a physical connection formed by wires or other electrical connectors, or a non-contact coupling connection formed by electromagnetic coupling. This application does not limit the specific electrical connection method between the power management module 120 and the wireless receiving module 110; furthermore, the electrical connection relationships involved in subsequent embodiments of this application can be referred to the description of this application's embodiments, and will not be repeated hereafter.

[0058] The power management module 120 can receive micro-current signals or power signals transmitted by the wireless receiving module 110, and can convert these micro-current signals or power signals into stable power that can power the operation of various modules. It is understood that the micro-current signals or power signals transmitted by the wireless receiving module 110 can be primary power, and the power management module 120 can convert them into secondary power. The power management module 120 can manage the micro-current signals or power signals transmitted by the wireless receiving module 110. For example, but not limited to, the power management module 120 can amplify, convert, distribute, and store the micro-current signals or power signals, so that primary power can be converted into secondary power and the secondary power can be managed in a unified manner. Therefore, the power management module 120 can realize the central control function of the passive electronic device 100.

[0059] The load module 130 can be directly or indirectly electrically connected to the power management module 120. The load module 130 can receive power signals (secondary power) transmitted by the power management module 120 and, under the supply of these power signals, can perform corresponding operations to realize the operation of the load module 130. It is understood that the load module 130 can be a functional module of the passive electronic device 100, enabling the passive electronic device 100 to possess corresponding functions. For example, when the load module 130 is a Bluetooth module or a near-field communication module with communication functions, the passive electronic device 100 can transmit Bluetooth signals, near-field communication signals, etc., to achieve wireless communication; as another example, when the load module 130 is a sensor module capable of collecting parameter information, the passive electronic device 100 can have the function of collecting corresponding parameters. Of course, the load module 130 in this embodiment may also include multiple functional units, so that the load module 130 can have different functions. For example, the load module 130 may simultaneously include a Bluetooth unit with communication function and a sensor unit that can collect parameter information, so that the load module 130 can both collect parameter information and transmit the parameter information to the outside. Based on this, this embodiment does not limit the specific structure of the load module 130. Any structure of the load module 130 that can operate under the power supply provided by the power management module 120 is within the protection scope of this embodiment.

[0060] The passive electronic device 100 of this application embodiment, in cooperation with the wireless receiving module 110 and the power management module 120, can convert wireless signals in space into electrical energy and supply this electrical energy to the load module 130 for operation. Therefore, the passive electronic device 100 of this application embodiment does not require traditional batteries for power supply, reconstructing the traditional energy transmission mechanism represented by batteries and wire transmission; it breaks through the reliability of radio frequency communication under extremely low power consumption and extends the scattering distance; it enables the possibility of wireless energy transmission in the communications industry; it can achieve "zero-power wireless radio frequency communication," possessing industry-leading features and market application compatibility; it can solve the problems of low-cost and sustainable operation of scenario-based, fragmented, and personalized smart terminals in the Internet of Things industry; it can effectively collect, redistribute, and utilize wireless micro-energy, realizing the reuse of wireless micro-energy, avoiding the waste of wireless micro-energy during energy crises, and improving the utilization rate of wireless micro-energy.

[0061] In this regard, please combine Figure 1 Please refer to Figure 3 , Figure 3 for Figure 1 The diagram shows a first structural schematic of the wireless receiving module 110. The wireless receiving module 110 can receive wireless signals in space, and can frequency-lock wireless signals of a specific frequency (including the corresponding electrical signals), and can convert the frequency-locked wireless signals (including the corresponding electrical signals) into micro-current signals or electrical energy signals (primary electrical energy). At this time, the power management module 120 can receive and manage the micro-current signal or electrical energy signal, and convert the micro-current signal or electrical energy signal into electrical energy (secondary electrical energy), so that the load module 130 can operate under the power (secondary electrical energy) supplied by the power management module 120.

[0062] like Figure 3 As shown, the wireless receiving module 110 may include a receiving antenna unit 111 and a radio frequency identification (RFID) unit 112. The receiving antenna unit 111 can receive wireless signals in space. The RFID unit 112 can be directly or indirectly electrically connected to the receiving antenna unit 111. The RFID unit 112 can convert the wireless signals received by the receiving antenna unit 111 into digital signals, and can perform frequency division and identification on the digital signals. The RFID unit 112 can also perform frequency locking on digital signals of a specific frequency.

[0063] The receiving antenna unit 111 can capture micro-energy at different frequencies scattered and propagating in space. The receiving antenna unit 111 can be a highly sensitive probe-type antenna. Because radio frequency signals scatter in space and exist in the surrounding environment, they are invisible and intangible to the human eye, and various radio frequency signals are mixed in complex environments and cannot be identified. The receiving antenna unit 111 of this embodiment can quickly find specific frequency signals and eliminate interference from other wireless signals. The receiving antenna unit 111 of this embodiment can adaptively tune its frequency to receive wireless signals in space within a frequency range of approximately 800MHz to 2.4GHz. The gain and sensitivity of the receiving antenna unit 111 can range from 0 to +15dB, and the maximum cannot exceed +20dB as stipulated by the Radio Management Committee. The signal received by the receiving antenna unit 111 can quickly reach the radio frequency identification unit 112.

[0064] It is understood that the receiving antenna unit 111 in this embodiment may include both an antenna radiator for receiving signals and an antenna radio frequency circuit. The antenna radio frequency circuit can convert the electromagnetic wave signal received by the antenna radiator into an electrical signal and form a reference signal source, so that the receiving antenna unit 111 can quickly transmit the reference signal source to the radio frequency identification unit 112. Of course, the antenna radio frequency circuit can also be integrated into other modules of the passive electronic device 100, for example, the wireless radio frequency circuit can also be integrated into the radio frequency identification unit 112. This embodiment does not limit the specific structure of the receiving antenna unit 111.

[0065] The radio frequency identification (RFID) unit 112 can receive the wireless signal transmitted by the antenna unit 111 and process the wireless signal to obtain a digital signal corresponding to the wireless signal; the RFID unit 112 can also receive the electrical signal corresponding to the wireless signal transmitted by the antenna unit 111 and convert the electrical signal into a digital signal. The RFID unit 112 can identify, divide, and analyze the digital signal corresponding to the wireless signal transmitted by the antenna unit 111, and perform frequency locking operation on signals of specific frequencies.

[0066] It is understandable that the specific frequency at which the RFID unit 112 performs frequency locking operation can be a preset frequency. The RFID unit 112 can identify, divide, and analyze the wireless signals transmitted by the receiving antenna unit 111, and extract signals of a specific frequency for frequency locking operation. For example, the wireless receiving module 110 (e.g., the RFID unit 112, or the power control unit 113 described later) can be activated by the electrical signal or micro-current signal converted from the wireless signal received by the receiving antenna unit 111, and transmit a preset frequency to the receiving antenna unit 111 (e.g., the RF circuit of the receiving antenna unit 111) so that the receiving antenna unit 111 can capture more wireless signals of that preset frequency. Of course, the activated wireless receiving module 110 can also transmit the preset frequency to the RFID unit 112 so that the RFID unit 112 can perform frequency locking on the signal of that preset frequency.

[0067] It is understandable that the specific frequency at which the RFID unit 112 performs frequency locking can be an adaptively determined frequency after analyzing the signal transmitted by the receiving antenna unit 111. For example, the RFID unit 112 can identify the signal with the best signal strength and gain effect among the digital signals corresponding to the wireless signal, and use the frequency of the identified signal as the specific frequency to further lock the digital signal corresponding to the wireless signal at that specific frequency, and convert the digital signal corresponding to the frequency-locked wireless signal into a micro-current signal or an electrical energy signal. It is also understandable that the wireless receiving module 110 can store or transmit this specific frequency parameter to the receiving antenna unit 111 or the RFID unit 112, so that the receiving antenna unit 111 or the RFID unit 112 can quickly capture and lock the signal at that specific frequency.

[0068] It is understandable that the specific frequency at which the RFID unit 112 performs frequency locking operation can adapt to changes in the environment. For example, if the original specific frequency is interfered with in a certain environment, the RFID unit 112 can switch to another specific frequency for frequency locking operation. This other specific frequency can be frequency data pre-stored in the wireless receiving module 110, or frequency data adaptively determined by the RFID unit 112 based on the signal received by the receiving antenna unit 111.

[0069] It should be noted that the above is merely an exemplary example of the RFID unit 112 locking a specific frequency wireless signal according to the embodiments of this application, and it is not limited thereto. Any scheme that enables the RFID unit 112 to perform frequency locking operation is within the protection scope of the embodiments of this application.

[0070] It is understandable that the RFID unit 112 can transmit the frequency-locked digital signal to the power management module 120 for subsequent operations; the RFID unit 112 can also further amplify the frequency-locked digital signal into a micro-current signal or a power signal, so that a portion of the energy of the micro-current signal or power signal can power the wireless receiving module 110 (e.g., the receiving antenna unit 111) and the RFID unit 112 itself, while the energy of the other portion of the micro-current signal or power signal can be transmitted to the power management module 120 for subsequent operations. Of course, the RFID unit 112 can also transmit the frequency-locked digital signal to the power control unit in subsequent embodiments (e.g., as described below). Figure 5 The corresponding operations are performed in the power control unit 113 shown. This application embodiment does not limit the operations performed after the radio frequency identification unit 112 is frequency-locked.

[0071] It is understood that the radio frequency identification unit 112 may be, but is not limited to, a circuit-integrated chip structure, or a structure integrating different independent devices. The specific structure of the radio frequency identification unit 112 is not limited in the embodiments of this application.

[0072] The wireless receiving module 110 of this application embodiment can capture wireless signals in space. The wireless receiving module 110 can also lock the frequency of wireless signals at a specific frequency and convert the frequency-locked wireless signals into electrical energy. Therefore, on the one hand, the wireless receiving module 110 of this application embodiment can adaptively capture micro-energy sources based on their frequency of scattering propagation in space. The wireless receiving module 110 can actively and accurately identify and capture micro-energy sources in multiple frequency bands (e.g., 800MHz to 2.4GHz), which can improve the sensitivity and efficiency of the wireless receiving module 110 in receiving wireless signals. On the other hand, the wireless receiving module 110 of this application embodiment can also adapt to micro-energy sources in a wider frequency band, making the passive electronic device 100 of this application embodiment applicable to a wider range of scenarios.

[0073] In this regard, please combine Figure 3 Please refer to Figure 4 , Figure 4 for Figure 3 The diagram shows a structural schematic of the RFID unit 112. The RFID unit 112 may include an analog frequency generator 1121, a frequency tuner 1122, and a frequency lock 1123.

[0074] The analog frequency generator 1121 can be directly or indirectly electrically connected to the receiving antenna unit 111. The analog frequency generator 1121 can convert the wireless signal received by the receiving antenna unit 111 into a digital signal. It is understood that in this process, either the receiving antenna unit 111 first converts the received wireless signal into a corresponding electrical signal and transmits the electrical signal to the analog frequency generator 1121, and then the analog frequency generator 1121 converts the electrical signal corresponding to the wireless signal into a digital signal; or the receiving antenna unit 111 directly transmits the received wireless signal to the analog frequency generator 1121, and then the internal circuitry of the analog frequency generator 1121 converts the wireless signal into a digital signal. It should be noted that the specific working process of the analog frequency generator 1121 is not limited in this embodiment.

[0075] It is understood that the analog frequency generator 1121 may include, but is not limited to, an analog-to-digital converter. This application does not limit the specific structure of the analog frequency generator 1121.

[0076] The frequency tuner 1122 can be directly or indirectly electrically connected to the analog frequency generator 1121. The frequency tuner 1122 can perform operations such as identification, analysis, and frequency division on digital signals, thereby dividing the multi-band (e.g., 800MHz to 2.4GHz) micro-energy signals received by the antenna receiving unit into frequencies, so that the frequency lock unit 1123 can lock the signal at a specific frequency. For example, the frequency tuner 1122 retains signals related to a specific frequency from the micro-energy signals received by the receiving antenna unit 111 while filtering out signals of other frequencies. As another example, the frequency tuner 1122 can divide the micro-energy signals received by the receiving antenna unit 111 into energy frequency band signals (e.g., but not limited to the 915MHz band) and communication frequency band signals (e.g., but not limited to the 2.4GHz band). Therefore, the wireless receiving module 110 of this embodiment can realize wireless radio frequency micro-energy acquisition and achieve dual functions of energy transmission and communication transmission.

[0077] It is understood that, in order to further divide the micro-energy signal, the frequency tuner 1122 can also perform other processing on the digital signal, such as, but not limited to, tuning the digital signal. This application embodiment does not limit the specific operating mode of the frequency tuner 1122.

[0078] The frequency lock 1123 can be directly or indirectly connected to the frequency tuner 1122. The frequency lock 1123 can lock the frequency of a digital signal of a specific frequency in order to capture more signals of that specific frequency.

[0079] It is understood that the frequency lock 1123 can perform frequency locking by determining a specific frequency based on the signal with the best signal strength and better gain effect from the digital signal analyzed by the frequency tuner 1122; or it can perform frequency locking based on specific frequency parameters pre-stored by the passive electronic device 100. Of course, the frequency lock 1123 can also perform frequency locking in other ways, and the specific working method of the frequency lock 1123 is not limited in this embodiment.

[0080] It is understandable that after the frequency locker 1123 performs a frequency lock operation on a signal of a specific frequency, it can divide the frequency-locked signal into multiple frequency bands, such as energy frequency band signals and communication frequency band signals. Then, these different frequency band signals can be transmitted to other modules of the passive electronic device 100. For example, the energy frequency band signal can be transmitted to the power management module 120, so that the power management module 120 can convert the energy frequency band signal into secondary electrical energy to power the entire passive electronic device 100. Another example is that the communication frequency band signal can be transmitted to the load module 130 of the passive electronic device 100, so that the load module 130 can use the communication frequency band signal for communication. It is understandable that in actual operation, the energy frequency band signal can achieve the function of converting it into secondary electrical energy; the communication frequency band signal can achieve both the function of converting it into secondary electrical energy and the function of converting it into a communication signal. It is understood that in actual operation, the load module of the passive electronic device 100 can use the communication frequency band signal for communication, and the load module of the passive electronic device 100 can also automatically generate the communication frequency band signal for communication when powered by electricity. This application embodiment does not limit the specific functions of the energy frequency band signal and the communication frequency band signal.

[0081] It should be noted that the above is merely an exemplary example of the operation mode of the frequency lock 1123. The specific operation mode of the frequency lock 1123 is not limited to this. For example, but not limited to, the frequency lock 1123 may only perform frequency locking without performing frequency division on the frequency-locked signal. This application embodiment does not limit the specific operation mode of the frequency lock 1123.

[0082] It should be noted that the above is merely an exemplary example of the radio frequency identification (RFID) unit 112 in this application embodiment, and the specific structure of the RFID unit 112 is not limited thereto. For example, but not limited to, it may also include other circuit structures. This application embodiment does not limit the specific structure of the RFID unit 112.

[0083] The radio frequency identification (RFID) unit 112 in this embodiment includes an analog frequency generator 1121, a frequency tuner 1122, and a frequency lock 1123. The three components work together. When a valid radio frequency signal is detected and captured, the RFID unit 112 can quickly and adaptively capture the oscillation frequency point of a specific frequency and complete the resonance at the same frequency. Thus, the RFID unit 112 can adaptively and quickly convert the wireless signal into a micro-current signal or an electrical signal.

[0084] In this regard, please combine Figure 1 Please refer to Figure 5 , Figure 5 for Figure 1 The diagram shows a second structural representation of the wireless receiver module 110. The wireless receiver module 110 in this embodiment may further include a power control unit 113.

[0085] The power control unit 113 can be directly or indirectly electrically connected to the radio frequency identification unit 112. The power control unit 113 can receive the frequency-locked signal, such as a digital signal, transmitted by the radio frequency identification unit 112, and amplify the signal, such as the digital signal, to form a micro-current signal or an electrical energy signal (i.e., primary electrical energy). The power control unit 113 can also perform management operations such as distribution and storage of the micro-current signal or electrical energy signal so that the primary electrical energy formed by the micro-current signal or electrical energy signal can support the normal operation of the entire wireless receiving module 110.

[0086] Understandably, the power control unit 113 can transmit primary power formed by microcurrent signals or power signals to the radio frequency identification unit 112 and the receiving antenna unit 111 to maintain the normal operation of the radio frequency identification unit 112 and the receiving antenna unit 111. When there is excess energy in the primary power stored in the power control unit 113 after maintaining the normal operation of the radio frequency identification unit 112 and the receiving antenna unit 111, the power control unit 113 can also transmit the excess energy to the power management module 120 to activate the power management module 120 and enable the power management module 120 to work.

[0087] The wireless receiving module 110 of this application embodiment includes a receiving antenna unit 111, a radio frequency identification unit 112, and a power control unit 113. The receiving antenna unit 111 can capture micro-energy signals from space, the radio frequency identification unit 112 can identify, divide, and lock the micro-energy signals, and the power control unit 113 can store and manage the frequency-locked signals. Thus, the micro-energy signals can activate the radio frequency identification unit 112, and excess micro-energy can be continuously stored in the power control unit 113, forming an effective positive feedback mechanism, enabling the entire wireless receiving module 110 to operate without battery excitation.

[0088] In this regard, please combine Figure 5 Please refer to Figure 6 , Figure 6 for Figure 5 The diagram shows a structural schematic of the power control unit 113. The power control unit 113 in this embodiment may include a reference signal source circuit 1131, an excitation gain circuit 1132, and a micro-energy storage management circuit 1133.

[0089] The reference signal source circuit 1131 can be directly or indirectly electrically connected to the frequency locker 1123. The reference signal source circuit 1131 can receive the frequency-locked signal, such as a digital signal, transmitted by the frequency locker 1123.

[0090] The excitation gain circuit 1132 can be directly or indirectly electrically connected to the reference signal source circuit 1131. The excitation gain circuit 1132 can amplify the frequency-locked signal, such as a digital signal, and generate a first-level electrical energy signal in the form of a micro-current signal or an electrical energy signal. It can be understood that the excitation gain circuit 1132 can amplify the frequency-locked signal, such as a digital signal, by increasing the gain to a certain factor, thereby generating a nanoampere-level micro-current signal or electrical energy signal.

[0091] The micro-energy storage management circuit 1133 can be directly or indirectly electrically connected to the excitation gain circuit 1132. The micro-energy storage management circuit 1133 can manage the amplified micro-current signal or electrical energy signal from the excitation gain circuit 1132. For example, the micro-energy storage management circuit 1133 may contain a small capacitor to store the first-order electrical energy of the amplified micro-current signal or electrical energy signal. Furthermore, the micro-energy storage management circuit 1133 can transmit a portion of the stored micro-current signal or electrical energy signal to the receiving antenna unit 111 and the RFID unit 112 according to their operational requirements, to maintain their normal operation. For yet another example, the micro-energy storage management circuit 1133 can transmit excess micro-current signal or electrical energy signal after maintaining the normal operation of the wireless receiving module 110 to the power management module 120 to activate and maintain the operation of the power management module 120.

[0092] It should be noted that the above is merely an exemplary description of the power control unit 113 in this application embodiment. The specific structure of the power control unit 113 is not limited thereto. For example, but not limited to, the power control unit 113 can combine one or more of the reference signal source circuit 1131, the excitation gain circuit 1132, and the micro energy storage management circuit 1133 into a single circuit structure; furthermore, the power control unit 113 may include more circuit structures. This application embodiment does not limit the specific structure of the power control unit 113. Any structure that can amplify and manage the signal after frequency locking by the radio frequency identification unit 112 is within the protection scope of this application embodiment.

[0093] The power control unit 113 of this application embodiment includes a reference signal source circuit 1131, an excitation gain circuit 1132, and a micro energy storage management circuit 1133. The three components work together to amplify and store the signal after frequency locking by the radio frequency identification unit 112. The power control unit 113 can complete the first stage of amplification, storage, and management of the micro energy signal.

[0094] It should be noted that the above are merely exemplary examples of the wireless receiving module 110 in this application embodiment. The wireless receiving module 110 in this application embodiment is not limited to this, and may include other structures with more functions, for example, but not limited to. The specific structure of the wireless receiving module 110 is not limited in this application embodiment.

[0095] Please refer to this again. Figure 1 In this embodiment of the application, the power management module 120 can receive micro-current signals or power signals (primary power) transmitted by the wireless receiving module 110, and can convert the micro-current signals or power signals into stable output aggregated power (secondary power). At this time, the load module 130 can operate under the supply of the stable output aggregated power.

[0096] It is understandable that, since the wireless receiving module 110 needs to convert the scattered micro-energy signals in space into micro-current signals or electrical signals, the micro-current signals or electrical signals transmitted by the wireless receiving module 110 to the power management module 120 are often in the form of AC electrical signals. The power management module 120 can collect and mix the micro-current signals or electrical signals transmitted by the wireless receiving module 110 within a preset unit time period into a group, and extract and nominally package the micro-current signals or electrical signals with similar characteristics in each group, so that the AC micro-current signals or electrical signals can be converted into stable output aggregated electrical energy. This stable output aggregated electrical energy can be supplied to the load module 130 so that the load module 130 can work normally. It should be noted that the above is only an exemplary example of the power management module 120 realizing stable output aggregated electrical energy. For example, but not limited to, the power management module 120 may include a rectifier and realize the above function through the rectifier. This application embodiment does not limit the specific method of the power management module 120 realizing stable output aggregated electrical energy.

[0097] It is understood that the power management module 120 can also store the aggregated electrical energy output stably. For example, but not limited to, the power management module 120 may include a supercapacitor structure to store electrical energy. The load module 130 and the wireless receiving module 110 can maintain normal operation under the power of the stored electrical energy. Of course, the passive electronic device 100 may also include a separate energy storage module, which can be electrically connected to the power management module 120 to receive and store the aggregated electrical energy output by the power management module 120. At the same time, the energy storage module can also be directly or indirectly electrically connected to other modules of the passive electronic device 100, such as the wireless receiving module 110 and the load module 130, to maintain their normal operation. It should be noted that the specific method of storing aggregated electrical energy is not limited in the embodiments of this application.

[0098] The power management module 120 of this application embodiment can convert the power signal or micro-current signal transmitted by the wireless receiving module 110 into a stable output of aggregated power, which can ensure the normal operation of the load module 130. Therefore, the power management module 120 of this application can convert micro-energy signals into stable output of aggregated power without complex hardware structure support. The power management module 120 has a simple structure, is easy to operate, has lower energy storage costs, and better power supply performance.

[0099] In this regard, please combine Figure 1 Please refer to Figure 7 and Figure 8 , Figure 7 for Figure 1 The diagram shown is a first structural schematic of the power management module 120. Figure 8 for Figure 7 The diagram shows an electrical connection of the power management module 120. The power management module 120 may include an amplification unit 121 and a power management unit 122.

[0100] Amplification unit 121 can be directly or indirectly electrically connected to wireless receiving module 110. For example, amplification unit 121 can be directly or indirectly electrically connected to the power control unit 113 of wireless receiving module 110. Furthermore, amplification unit 121 can be directly or indirectly electrically connected to the micro-energy storage management circuit 1133 of power control unit 113. Amplification unit 121 can receive micro-current signals or power signals transmitted by wireless receiving module 110 and amplify such micro-current signals or power signals. Amplification unit 121 can synchronously and invert and amplify nanoampere-level micro-current signals or power or micro-currents transmitted by wireless receiving module 110, and amplification unit 121 can realize two-stage amplification of micro-energy.

[0101] It is understood that the amplification unit 121 may be, but is not limited to, a power amplifier. This application does not limit the specific structure of the amplification unit 121; any circuit or structure capable of amplifying electrical signals or microcurrents is within the protection scope of this application.

[0102] The power management unit 122 can be directly or indirectly electrically connected to the amplification unit 121. The power management unit 122 can effectively manage the amplified micro-current signal or power signal transmitted by the amplification unit 121. The power management unit 122 can convert the amplified micro-current signal or power signal into a stable output of aggregated power. For example, the power management unit 122 can employ an energy recovery algorithm, which uses an energy point innovative feature set mixing algorithm to achieve stable output of aggregated power. Specifically, the power management unit 122 can collect and mix the micro-current signal or power signal transmitted by the wireless receiving module 110 within a preset unit time period into a group, and extract and nominally package the micro-current signal or power signal with similar characteristics in each group, so that the AC-characteristic micro-current signal or power signal can form a stable output of aggregated power. This stable output of aggregated power can be supplied to the load module 130 to ensure the normal operation of the load module 130. Understandably, when the power management unit 122 nominally packages micro-current signals or power signals into aggregated power, it can mark the aggregated power with electrical characteristics. For example, it can mark the aggregated power as aggregated power with N volts and M amps. Thus, the power management unit 122 can manage the power based on the marked aggregated power. For example, but not limited to, the power management unit 122 can calculate the current power reserve of the passive electronic device 100, calculate the duration of the current wireless radio frequency micro-energy acquisition by the passive electronic device 100, calculate the duration interval of the next wireless radio frequency micro-energy acquisition by the passive electronic device 100, and so on.

[0103] It should be noted that the above is merely an exemplary example of how the power management unit 122 achieves stable output of aggregated electrical energy. The power management unit 122 can also achieve the above functions in other ways, such as, but not limited to, using a rectifier. This application does not limit the specific method by which the power management unit 122 achieves stable output of aggregated electrical energy.

[0104] It is understood that the power management unit 122 can also be directly or indirectly electrically connected to the wireless receiving module 110. For example, the power management unit 122 can be directly or indirectly electrically connected to the power control unit 113 of the wireless receiving module 110. Furthermore, the power management unit 122 can be directly or indirectly electrically connected to the micro-energy storage management circuit 1133 of the power control unit 113. The power management unit 122 can be activated and put into operation under the excitation of the micro-current signal or electrical signal transmitted by the wireless receiving module 110, thereby converting the micro-current signal or electrical signal amplified by the amplification unit 121 into a stable output of aggregated electrical energy. Of course, the power management unit 122 can also be activated and put into operation under the action of the amplified micro-current signal or electrical signal provided by the amplification unit 121, thereby achieving a stable output of aggregated electrical energy. It should be noted that the specific method of the power management unit 122 is not limited in the embodiments of this application. Any working method that can convert the amplified electrical signal or power signal or microcurrent of the amplification unit 121 into stable output aggregated power is within the protection scope of the embodiments of this application.

[0105] It is understood that the power management unit 122 can also store aggregated electrical energy. For example, the power management unit 122 may include an energy storage unit, such as, but not limited to, a supercapacitor, which can store the aggregated electrical energy converted by the power management unit 122 and can transfer the aggregated electrical energy to other modules when other modules need power support.

[0106] Of course, in other embodiments, please refer to Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of a second structure of the passive electronic device 100 provided in an embodiment of this application. Figure 10 for Figure 1 The diagram shows a second structural representation of the power management module 120, as follows: Figure 9 As shown, the passive electronic device 100 can be equipped with a separate energy storage unit 140; or as... Figure 10 As shown, the power management module 120 can be equipped with a separate power storage unit 124. This power storage unit 140 or power storage unit 124 can be directly or indirectly electrically connected to the power management module 120, such as the power management unit 122, to store the aggregated power transmitted by the power management unit 122, and can provide power support for other modules. Therefore, the specific storage method of this aggregated power is not limited in this embodiment.

[0107] The power management module 120 of this application embodiment includes an amplification unit 121 and a power management unit 122. The amplification unit 121 can realize the secondary inversion amplification of the micro current signal or power signal transmitted by the wireless receiving module 110. The power management unit 122 can effectively combine the amplified weak energy with AC characteristics into a stable output aggregated energy. This aggregated energy can effectively ensure the normal operation of the power management module 120 and the load module 130.

[0108] In this regard, please combine Figure 7 , Figure 8 Please refer to Figure 11 , Figure 11 for Figure 1 The diagram shows a third structural design of the power management module 120. The power management module 120 may also include a control management unit 123.

[0109] The control management unit 123 can be directly or indirectly electrically connected to at least one of the other units in the power management module 120, the wireless receiving module 110, and the load module 130. The control management unit 123 can be directly or indirectly electrically connected to the power management unit 122. The power management unit 122 can transmit stable aggregated power to the control management unit 123, and the control management unit 123 can receive the aggregated power and activate its operation.

[0110] The control management unit 123 can be directly or indirectly electrically connected to the amplification unit 121. The control management unit 123 can control the operation of the amplification unit 121 based on the aggregated electrical energy transmitted by the power management unit 122. For example, the control management unit 123 can control the amplification factor of the amplification unit 121. It is understood that the amplification unit 121 can receive micro-current signals or electrical energy signals transmitted by the wireless receiving module 110, such as the micro-energy storage management circuit 1133. First, it amplifies the micro-current signal or electrical energy signal according to a preset amplification factor (e.g., amplification by one time), and then transmits the amplified micro-current signal or electrical energy signal to the power management unit 122 to form aggregated electrical energy, so that the control management unit 123 can be activated by the aggregated electrical energy, and the control management unit 123 can be quickly activated. Subsequently, the control management unit 123 can control and adjust the multiplier of the amplification unit 121 (e.g., adjust it to amplify by two times, three times, etc.) according to the aggregated electrical energy transmitted by the power management unit 122. The amplification unit 121 can continue to amplify the received micro-current signal or electrical energy signal according to the adjusted amplification multiplier, which can make the conversion rate of aggregated electrical energy faster. It is understood that during this process, the control management unit 123 can adjust the operating parameters of the amplification unit 121 multiple times according to the actual situation. The embodiments of this application do not limit the specific operating mode of the control management unit 123 controlling the amplification unit 121.

[0111] It is understood that the control management unit 123 can also be electrically connected to the load module 130. The control management unit 123 can control the power management unit 122 or the power storage unit to provide power to the load module 130 based on the operating parameters of the load module 130, ensuring the normal operation of the load module 130. It is also understood that the control management unit 123 can reversely control the operation of the amplification unit 121 and the power management unit 122 based on the operating state of the load module 130 (e.g., the power consumption of the load module 130). For example, it can adjust the amplification factor of the amplification unit 121 and the power allocation ratio of the power management unit 122 to the load module 130 based on the operating state of the load module 130. This application embodiment does not limit the specific control method of the control management unit 123 over the load module 130, the amplification unit 121, and the power management unit 122.

[0112] The control management unit 123 can also be directly or indirectly electrically connected to the wireless receiving module 110, and the control management unit 123 can also control the wireless receiving module 110. For example, but not limited to, when the aggregated electrical energy stored in the passive electronic device 100 reaches a certain level, it is no longer necessary to convert micro-energy into aggregated electrical energy. At this time, the control management unit 123 can control the wireless receiving module 110 to stop working. It should be noted that the above is only an exemplary specific example of the control management unit 123 controlling the wireless receiving module 110, and other control schemes are also within the protection scope of the embodiments of this application.

[0113] It is understood that the control management unit 123 can be a microcontroller unit (MCU). The control management unit 123 can be a miniature computing center for the entire passive electronic device 100. The control management unit 123 can operate under the excitation of the aggregated energy provided by the power management unit 122, and can undertake the calculation of the effective signal source for the amplification unit 121, as well as control the operation of the load module 130. Therefore, the control management unit 123 can control various modules and units of the passive electronic device 100, which will not be detailed here.

[0114] The power management module 120 of this application embodiment includes an amplification unit 121, a power management unit 122, and a control management unit 123. The three modules work independently but can also cooperate with each other. The amplification unit 121 can synchronously invert and amplify the basic signal (micro-current signal / power signal) transmitted by the wireless receiving module 110. The primary power stored in the wireless receiving module 110 can activate and wake up the power management unit 122, which can be quickly activated, thus improving the response rate of the passive electronic device 100. At the same time, the power management unit 122 can convert the signal amplified by the amplification unit 121 into a stable output aggregated energy. The control management unit 123 can process the business logic information between the various modules and units of the passive electronic device 100 according to the working status of the passive electronic device 100.

[0115] Please refer to this again. Figure 7 Please refer to Figure 12 , Figure 12 for Figure 7 The diagram shows a structural schematic of the amplification unit 121. The amplification unit 121 may include a reference sampling circuit 1211, a multiplier amplifier circuit 1212, and an amplification feedback circuit 1213.

[0116] The reference sampling circuit 1211 can be directly or indirectly electrically connected to the wireless receiving module 110, such as the power control unit 113 or the micro energy storage management circuit 1133 of the wireless receiving module 110. The reference sampling circuit 1211 can receive the micro current signal or power signal transmitted by the wireless receiving module 110. The multiplier amplifier circuit 1212 can be directly or indirectly electrically connected to the reference sampling circuit 1211. The multiplier amplifier circuit 1212 can amplify the received micro current signal or power signal by a certain factor, performing a two-stage inverter amplification of the micro current signal or power signal.

[0117] It is understood that the multiplier amplifier circuit 1212 can be directly or indirectly electrically connected to the power management unit 122, so that the multiplier amplifier circuit 1212 can transmit the inverter-amplified signal to the power management unit 122. Of course, the multiplier amplifier circuit 1212 can also transmit the amplified signal to the amplification feedback circuit 1213, and the amplification feedback circuit 1213 can then transmit the inverter-amplified signal to the power management unit 122. This application embodiment does not limit the specific method by which the amplified electrical signal is transmitted to the power management unit 122.

[0118] It is understood that the amplification feedback circuit 1213 can be directly or indirectly electrically connected to the multiplier amplifier circuit 1212. The amplification feedback circuit 1213 can also be directly or indirectly electrically connected to the control management unit 123 of the power management module 120 (described later). The amplification feedback circuit 1213 can receive the amplification factor adjustment information transmitted by the control management unit 123, and can transmit this adjustment information to the multiplier amplifier circuit 1212 so that the multiplier amplifier circuit 1212 can amplify the received electrical signal, electrical energy, or microcurrent according to the adjusted amplification factor.

[0119] The amplification circuit of this embodiment includes a reference sampling circuit 1211, a multiplier amplification circuit 1212, and an amplification feedback circuit 1213 that cooperate and coordinate with each other. It can realize secondary inversion amplification of micro-current signals or electrical energy signals, and can also be controlled by the control management unit 123 to adaptively control the secondary inversion amplification of micro-current signals or electrical energy signals. Thus, the amplification circuit of this embodiment can enable weak signal sources to achieve effective voltage and current stabilization in the power management module 120.

[0120] It should be noted that the above is merely an exemplary description of the amplification unit 121 provided in the embodiments of this application. The specific structure of the amplification unit 121 is not limited to this. For example, but not limited to, the amplification unit 121 may also include multi-stage multiplier amplification circuits. Any structure that can perform two-stage inverter amplification of the micro-current signal or electrical signal transmitted by the wireless receiving module 110 is within the protection scope of the amplification unit 121 in the embodiments of this application.

[0121] It should be noted that the above is only an exemplary description of the power management module 120 provided in the embodiments of this application. The specific structure of the power management module 120 is not limited thereto. For example, the power management module 120 may include more or fewer modules. The embodiments of this application do not limit the specific structure of the power management module 120. Any structural scheme that can receive the micro-current signal or power signal transmitted by the wireless receiving module 110 and convert it into power (secondary power) is within the protection scope of the embodiments of this application.

[0122] Please refer to the following: Figure 13 , Figure 13 This is a schematic diagram of a third structure of the passive electronic device 100 provided in an embodiment of this application. The load module 130 of the passive electronic device 100 may include a Bluetooth unit 131.

[0123] Bluetooth unit 131 can be directly or indirectly electrically connected to power management module 120. Bluetooth unit 131 can transmit signals, such as broadcasting signals, when supplied with power by power management module 120. For example, when power management module 120 receives microcurrent signals or power signals (primary power) transmitted by wireless receiving module 110 and converts the microcurrent signals or power signals (secondary power) into stable aggregated power, Bluetooth unit 131 can broadcast signals when supplied with stable aggregated power by power management module 120.

[0124] It is understood that Bluetooth unit 131 can be directly or indirectly electrically connected to power management unit 122 of power management module 120 to receive aggregated power transmitted by power management unit 122. Bluetooth unit 131 can also be directly or indirectly electrically connected to energy storage unit storing aggregated power to receive aggregated power transmitted by energy storage unit. Bluetooth unit 131 can also be directly or indirectly electrically connected to control management unit 123 of power management module 120 to receive control from control management unit 123. For example, control management unit 123 can control Bluetooth unit 131 to broadcast signals under certain triggering conditions and stop broadcasting signals under other certain triggering conditions.

[0125] It is understood that when other electronic terminals receive the broadcast signal transmitted by Bluetooth unit 131, they can identify Bluetooth unit 131 or passive electronic device 100 to perform corresponding functions. For example, after Bluetooth unit 131 or passive electronic device 100 is identified, it can, but is not limited to, implement the positioning function, QR code scanning function, and content push function of passive electronic device 100. This application embodiment does not limit the specific application scenarios of Bluetooth unit 131.

[0126] It is understood that Bluetooth unit 131 can independently parse a specific part of the BLE protocol stack and can actively broadcast wireless signals and send Becan signals. In this embodiment, Bluetooth unit 131 can only transmit broadcast signals without receiving signals. Bluetooth unit 131 may not include hardware and software structures adapted to signal receiving functions. Bluetooth unit 131 can be a simplified design as a BLE signal RF transmitter. This Bluetooth unit 131 can ensure compatibility with the internationally accepted Bluetooth protocol stack while maintaining extremely low power consumption, and can also consider the power of the transmitted signal to ensure a good wireless sensing experience for the receiving terminal (e.g., the subsequent electronic terminal 300). Furthermore, during the use of Bluetooth unit 131, the connection and disconnection of Bluetooth unit 131 is a 0-1 switch. Bluetooth unit 131 either transmits signals (e.g., broadcast signals) or stops transmitting signals, equivalent to a state change within a fixed scenario. Therefore, the active uploading and transmitting of Bluetooth unit 131 in this application is far more significant than the passive reception of traditional Ultra High Frequency (UHF) signals. The Bluetooth unit 131 of this application will be a good network for future Internet of Things (IoT) self-organizing network expansion applications.

[0127] The Bluetooth unit 131 of this application embodiment only broadcasts signals and does not receive signals, which makes the structure of the Bluetooth unit 131 of this application embodiment simpler and lower in cost, and also allows the Bluetooth unit 131 of this application to work with extremely low power consumption. Therefore, the Bluetooth unit 131 of this application embodiment is more suitable for the passive electronic device 100 of this application.

[0128] In this regard, please combine Figure 13 Please refer to Figure 14 and Figure 15 , Figure 14 This is a schematic diagram of the fourth structure of the passive electronic device 100 provided in the embodiments of this application. Figure 15 This is a fifth structural schematic diagram of the passive electronic device 100 provided in the embodiments of this application. The load module 130 in the embodiments of this application may further include a sensor unit 132.

[0129] Sensor unit 132 may be, but is not limited to, a microsystem sensor (MEMS). Sensor unit 132 may be directly or indirectly electrically connected to power management module 120. Sensor unit 132 can collect parameter information under the power supply provided by power management module 120. For example, when power management module 120 receives a microcurrent signal or electrical signal (primary power) transmitted by wireless receiving module 110 and converts the microcurrent signal or electrical signal into stable output aggregated power (secondary power), sensor unit 132 can collect parameter information under the stable output aggregated power provided by power management module 120. It is understood that this parameter information may be, but is not limited to, parameter information of the passive electronic device 100 in the current environment, such as, but not limited to, temperature, humidity, pressure, height, and tilt information. Sensor unit 132 can collect parameters such as temperature, humidity, pressure, height, and tilt in the current environment of passive electronic device 100.

[0130] It is understood that sensor unit 132 can be directly or indirectly electrically connected to power management unit 122 of power management module 120 to receive aggregated electrical energy with stable output transmitted by power management unit 122. Sensor unit 132 can also be directly or indirectly electrically connected to energy storage unit storing aggregated electrical energy to receive aggregated electrical energy with stable output transmitted by energy storage unit. Sensor unit 132 can also be directly or indirectly electrically connected to control management unit 123 of power management module 120 to receive control from control management unit 123. For example, control management unit 123 can control sensor unit 132 to collect preset parameter information under certain trigger conditions and stop collecting preset parameter information under other certain trigger conditions.

[0131] It is understood that the load module 130 in this embodiment may include at least one of the sensor unit 132 and the Bluetooth unit 131. For example, as Figure 13 As shown, the load module 130 may include a Bluetooth unit 131 but not a sensor unit 132; for example, such as Figure 14 As shown, the load module 130 may include a sensor unit 132 but not a Bluetooth unit 131; for example, as Figure 15 As shown, the load module 130 may simultaneously include a Bluetooth unit 131 and a sensor unit 132. Furthermore, the load module 130 in this embodiment may include one or more Bluetooth units 131 and one or more sensor units 132. Therefore, this embodiment does not limit the configuration or number of Bluetooth units 131 and sensor units 132.

[0132] It is understood that the sensor unit 132 can communicate with other electronic terminals, servers, or cloud platforms. The sensor unit 132 can transmit the collected parameter information to other electronic terminals, servers, or cloud platforms so that the electronic terminals, servers, or cloud platforms can obtain relevant information about the passive electronic device 100 in the current environment.

[0133] Of course, the sensor unit 132 can also be directly or indirectly electrically connected to the Bluetooth unit 131. The sensor unit 132 can convert the collected relevant information into an electrical signal carrying information and send it to the Bluetooth unit 131. The Bluetooth unit 131 can actively broadcast the electrical signal. It should be noted that the above is only an exemplary description of the external transmission of parameter information collected by the sensor unit 132. This application embodiment does not limit the specific method of external transmission of parameter information collected by the sensor unit 132.

[0134] It is understood that the sensor unit 132 in this embodiment is a flexible design option within the overall framework of the passive electronic device 100. The passive electronic device 100 may or may not include the sensor unit 132. The sensor unit 132 can be used to perform spatial sensing of the current environmental parameters of the passive electronic device 100, such as temperature, humidity, pressure, and altitude, in different scenarios. Subsequently, the sensor unit 132 can be attached to a spatial wireless network node to wirelessly collect and report these parameters to the cloud platform server in real time. This not only enriches the feasibility of the entire system but also closely meets the needs of daily life, greatly satisfying the requirements of different scenarios.

[0135] The sensor unit 132 in this embodiment is a variable-loaded sensing unit that can collect parameter information of the passive electronic device 100 in the current environment and actively broadcast it to the cloud platform via Bluetooth unit 131. This can reduce the power consumption of the sensor unit 132, expand the application scenarios of the passive electronic device 100, and improve the adaptability of the passive electronic device 100.

[0136] Please refer to the following: Figure 16 and Figure 17 , Figure 16 This is a sixth structural schematic diagram of the passive electronic device 100 provided in the embodiments of this application. Figure 17 for Figure 16 The diagram shows an electrical connection of the passive electronic device 100. The passive electronic device 100 also includes an encrypted storage unit 150.

[0137] The encrypted storage unit 150 can be directly or indirectly electrically connected to at least one of the wireless receiving module 110, the power management module 120, and the load module 130. The encrypted storage unit 150 can store data and prevent unauthorized data tampering.

[0138] Understandably, the encrypted storage unit 150 can be responsible for saving, for example, encrypted storage of important configuration parameters of the passive electronic device 100 during normal operation when power is lost (power off), and can prevent malicious and illegal tampering with the data; at the same time, the redundant sectors on the encrypted storage unit 150 can store other data that can be randomly erased and rewritten. Thus, the encrypted storage unit 150 can ensure reasonable allocation of storage space within a limited storage space and good power consumption control of storage operations, achieving a two-way balance between energy consumption and access to content.

[0139] It is understood that the encrypted storage unit 150 prevents unauthorized data modification in ways including, but not limited to, only modifying data when a correct instruction is identified, and refusing to modify data for other erroneous instructions.

Thus, the encrypted storage unit 150 of this application embodiment can ensure that the storage space is reasonably configured within the limited storage space and that the storage operation is well controlled by power consumption, so as to achieve a two-way balance between energy consumption and access to content.

[0144] The passive electronic device 100 of this application embodiment, comprising a Bluetooth unit 131, an encrypted storage unit 150, and a sensor unit 132, can operate independently or collaboratively.

The encrypted storage unit 150 is responsible for encrypting and saving important configuration parameters even when power is lost, and redundant sectors can store other data that can be randomly erased and rewritten. The sensor unit 132, as a variable sensing load, can simulate signal acquisition parameters and then actively broadcast them along with the Bluetooth unit 131. Therefore, the passive electronic device 100 of this application embodiment can achieve a two-way balance between energy consumption and content access.
