Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Figure 1 This is a schematic diagram of the communication component provided in an embodiment of this application. (Refer to...) Figure 1 This application provides a communication component, which may include: an energy harvesting module, an energy storage module, and a load module; The energy harvesting module is used to: collect the radio frequency energy transmitted by the base station, convert the radio frequency energy into DC energy, and transmit the DC energy to the energy storage module; An energy storage module is used to store DC energy and transmit DC energy to a load module.

[0021] The energy storage module can be a capacitor with a large capacity.

[0022] The communication component provided in this embodiment includes an energy harvesting module, an energy storage module, and a load module. The energy harvesting module collects radio frequency (RF) energy transmitted from the base station, converts the RF energy into DC energy, and transmits the DC energy to the energy storage module. The energy storage module stores the DC energy and then transmits it to the load module. In this embodiment, the communication component collects RF energy transmitted from the base station through its internal energy harvesting module, converts it into DC energy, uses this DC energy to charge the internal energy storage module, and then transmits stable DC energy to the load module through the energy storage module to power the load module. This allows the load module to avoid energy consumption from self-powering, thereby reducing the overall energy consumption of the communication component. This embodiment does not require shutting down the communication component's processes or using low-power devices as the communication load, thus achieving energy consumption reduction of the communication component while avoiding limitations in energy reduction and increased device costs.

[0023] Reference Figure 1 In one embodiment, the communication component may further include: a first directional antenna and a first main antenna; The first directional antenna is used to: receive radio frequency energy, transmit the radio frequency energy to the energy harvesting module, and receive the energy limit signal sent by the energy harvesting module, and send the energy limit signal to the base station; the energy limit signal includes an upper energy limit signal and a lower energy limit signal. The first main antenna is used to: receive downlink wireless data transmitted by the base station and transmit the downlink wireless data to the load module, and receive uplink wireless data transmitted by the load module and transmit the uplink wireless data to the base station.

[0024] Reference Figure 1 The energy harvesting module includes a matching unit, a rectification unit, and an energy management unit. Since the output impedance of the first directional antenna is usually mismatched with the input impedance of the rectifier unit, it is easy to cause the reflection and loss of radio frequency energy. Therefore, a matching unit needs to be set between the two to adjust the output impedance of the first directional antenna so that it matches the input impedance of the rectifier unit, so as to ensure that the radio frequency energy can be efficiently transmitted from the first directional antenna to the rectifier unit. Since radio frequency energy is usually AC energy and cannot be powered by DC loads, a rectifier unit is set up to convert the radio frequency energy into DC energy and transmit the DC energy to the energy management unit. Because the energy storage module has an upper and lower storage limit, if DC energy continues to be transmitted after the upper storage limit is reached but the energy storage module cannot continue to store energy, it will lead to energy waste. If DC energy is not transmitted in time to replenish storage after the lower storage limit is reached, it will lead to insufficient power supply to the load module. Therefore, an energy management unit is set up. This unit has preset upper and lower energy storage limits. When the cumulative value of DC energy transmission has reached the upper energy storage limit, the unit will send an upper energy limit trigger signal to the first directional antenna. The first directional antenna will send this signal to the base station to notify the base station to stop transmitting radio frequency energy. When the cumulative value of DC energy transmission has only reached the lower energy storage limit, the unit will send a lower energy limit trigger signal to the first directional antenna. The first directional antenna will send this signal to the base station to notify the base station to start transmitting radio frequency energy.

[0025] Reference Figure 1 The load module includes a chip processor and an ADC (Analog-to-Digital Converter): The ADC receives the analog voltage signal from the energy storage module, converts it into a digital voltage signal, and sends it to the chip processor. The chip processor detects the data voltage signal, and if the detection is successful, the load module receives the DC energy transmitted by the energy storage module. The ADC receives the downlink wireless data transmitted by the first main antenna, converts the downlink wireless data from analog signal to digital signal, and sends it to the chip processor for further processing. The chip processor transmits the processed uplink wireless data to the first main antenna in analog signal form, so that the first main antenna can transmit the uplink wireless data to the base station.

[0026] In this embodiment, the communication component adopts a dual-antenna mode. One antenna communicates with the energy harvesting module for wireless radio frequency energy transmission and energy limit signal transmission, while the other antenna communicates with the load module for wireless data transmission. This ensures that energy transmission and data transmission do not interfere with each other and that both transmission and data transmission are stable. Furthermore, by setting adapter units in the energy harvesting module and the load module respectively, and connecting the energy harvesting module and the load module with an energy storage module, efficient and controllable energy storage and supply can be achieved.

[0027] In one embodiment, the load module can be used for: In the first working mode, when an external interrupt is generated or a preset internal timer event is triggered, uplink wireless data is transmitted to the base station, downlink wireless data is received from the base station, and then the system enters a sleep state. In the second working mode, it transmits uplink wireless data to the base station, periodically sends data query requests to the base station, receives downlink wireless data transmitted by the base station, and enters sleep mode. In the third operating mode, it transmits uplink wireless data to the base station and listens for and receives downlink wireless data transmitted by the base station.

[0028] in: In the first operating mode, after the communication component joins the network, its load module is almost always in a dormant state. To conserve energy, the load module does not attempt to receive downlink wireless data before initiating uplink wireless data transmission. Uplink wireless data transmission is only initiated when an external interrupt occurs or a preset internal timer event is triggered. After transmitting uplink wireless data to the base station, the load module opens its data receiving window to receive downlink wireless data transmitted by the base station, and then returns to a dormant state. The workflow of a complete operating cycle of the load module in the first operating mode can be described as follows: Figure 2 As shown, this includes one data transmission (i.e., uplink wireless data transmission) and one data reception (i.e., downlink wireless data reception); the energy consumption model of the load module for a complete working cycle in the first working mode can be as follows: Figure 3 As shown, this represents a complete duty cycle of the load module in the first operating mode. Total energy consumption It can be represented as follows: (1-1) Among them, reference Figure 3 It can be seen that, The power used for data transmission by the load module. The duration for the load module to send data. The power used for data reception by the load module. The duration for the load module to receive data. This represents the power of the load module in sleep mode.

[0029] In the second operating mode, after the communication component joins the network, its load module is mostly in a dormant state. However, in addition to transmitting uplink wireless data to the base station, the load module also actively and periodically sends data query requests to the base station. During the sending of data query requests, a data receiving window is opened and remains open until the downlink wireless data transmitted by the base station is completed, after which it enters a dormant state again. The workflow of a complete operating cycle of the load module in the second operating mode can be described as follows: Figure 4 As shown, this includes one data transmission (i.e., uplink wireless data transmission), multiple data requests (i.e., data query request transmission), and one data reception (i.e., downlink wireless data reception); the energy consumption model of the load module for a complete working cycle in the second working mode can be as follows: Figure 5 As shown, this represents a complete duty cycle of the load module in the second operating mode. Total energy consumption It can be represented as follows: (1-2) Among them, reference Figure 5 , The power required for the load module to make data requests. The duration for the load module to make data requests.

[0030] In the third operating mode, after the communication component joins the network, the load module never goes into sleep mode. Besides transmitting uplink wireless data to the base station, it also continuously listens for downlink wireless data transmitted by the base station, always keeping its data receiving window open to receive that downlink wireless data. The workflow of a complete working cycle of the load module in the third operating mode can be described as follows: Figure 6 As shown, this includes one data transmission (i.e., uplink wireless data transmission) and multiple data receptions (i.e., downlink wireless data reception); the energy consumption model of the load module for a complete working cycle in the third working mode can be as follows: Figure 7 As shown, this represents a complete working cycle of the load module in the third working mode. Total energy consumption It can be represented as follows: (1-3) According to formulas (1-1), (1-2), and (1-3), the duration for which the load module opens the data transmission window for the uplink communication link under the three operating modes is... They are the same, but for the downlink communication link: Duration of time the load module keeps the data receiving window open in the first operating mode The shortest path is when the load module has the lowest power consumption, but also the lowest downlink communication link reliability. Duration of time the load module keeps the data receiving window open in the third working mode At its longest, the load module has the highest energy consumption, but also the highest downlink communication link reliability. Duration of the load module's data receiving window open in the second operating mode Between and Between these two modes, the load module's energy consumption and downlink communication link reliability are also between the first and third working modes.

[0031] As shown above, from the first operating mode to the third operating mode, the downlink communication link reliability of the load module gradually increases as the data reception window opening time gradually increases, but the power consumption of the load module also gradually increases. Conversely, from the third operating mode to the first operating mode, the power consumption of the load module gradually decreases as the data reception window opening time gradually decreases, but the downlink communication link reliability of the load module also gradually decreases.

[0032] When the downlink communication data volume demand is large, the load module needs to extend the opening time of the data receiving window, and switch from the first working mode to the second working mode, or even the third working mode, in order to improve the reliability of the downlink communication link; when the downlink communication data volume demand is small, the load module needs to shorten the opening time of the data receiving window, and switch from the second or third working mode back to the first working mode, in order to reduce energy consumption.

[0033] Based on the ever-changing downlink communication data volume requirements, this embodiment considers the energy consumption of the load module in the communication component and the reliability of the downlink communication link. It designs three working modes that cooperate with the base station from the load module side, which correspond to different energy consumption and downlink communication link reliability of the load module. In this way, a suitable working mode can be selected for the ever-changing downlink communication data volume requirements, so as to achieve a balance between downlink communication data volume requirements, load module energy consumption and downlink communication link reliability.

[0034] In one embodiment, the DC power in the energy storage module can be divided into three levels—low, medium, and high—from low to high based on the discharge curve characteristics of the energy storage module; in addition, the downlink communication data demand per unit time can be divided into three levels—low, medium, and high—from low to high.

[0035] The load module can also be used for: In the first operating mode, when the DC power level in the energy storage module is medium and the downlink communication data demand level is medium or high, it indicates that the load module's power supply is average. For medium or high downlink communication data demands, the first operating mode can be switched to the second operating mode to improve the reliability of the downlink communication link and achieve better communication performance. When the DC power level in the energy storage module is high and the downlink communication data demand level is medium or high, it indicates that the load module's power supply is sufficient. For medium or high downlink communication data demands, the first operating mode can be switched to the third operating mode to maximize the reliability of the downlink communication link and improve communication performance to the maximum extent. Under other circumstances, the load module remains in the first operating mode. In the second operating mode, when the DC power level in the energy storage module is high and the downlink communication data volume demand level is medium or high, it indicates that the load module has sufficient power. When facing medium or high downlink communication data volume demand, the second operating mode can be switched to the third operating mode to improve the reliability of the downlink communication link and achieve better communication performance. When the DC power level in the energy storage module is low, it indicates that the load module has insufficient power. In this case, ensuring that the load module continues to work is more important than improving communication performance. Therefore, regardless of the downlink communication data volume demand, the second operating mode should be switched to the first operating mode to reduce the power consumption of the load module. Under other circumstances, the load module remains in the second operating mode. In the third operating mode, when the DC power level in the energy storage module is medium, it indicates that the power supply of the load module is average. In this case, the third operating mode can be switched to the second operating mode to reduce the power consumption of the load module without significantly affecting the communication performance. When the DC power level in the energy storage module is low, it indicates that the power supply of the load module is insufficient. In this case, it is also necessary to prioritize ensuring that the load module continues to work. Therefore, the third operating mode is switched to the first operating mode to minimize the power consumption of the load module. Under other circumstances, the load module remains in the third operating mode.

[0036] It should be noted that the load module can periodically execute a downlink communication link data volume calculation program to detect changes in downlink communication link data volume demand, and remain in a dormant state during the rest of the idle time to reduce energy consumption.

[0037] This embodiment classifies the DC power in the energy storage module and the downlink communication data volume requirement per unit time into different levels. This allows the load module to adaptively switch working modes based on different combinations of the two, achieving a balance between downlink communication data volume requirement, load module energy consumption, and downlink communication performance, ensuring that the passive IoT communication component continues to work without disconnection.

[0038] Figure 8 This is a schematic diagram of a base station provided in an embodiment of this application. (Refer to...) Figure 8 This application provides a base station, which may include: a radio frequency module; Radio frequency (RF) module, used to transmit wireless radio frequency energy to communication components.

[0039] In this embodiment, when the radio frequency module transmits wireless radio frequency energy to the communication component, the communication component can use this energy as its own energy source, thereby avoiding energy consumption caused by its own power supply and realizing a reduction in its own energy consumption. That is, there is no need to shut down the process of the communication component, nor is there a need to use low-power devices as communication loads. Therefore, it is possible to reduce the energy consumption of the communication component while avoiding the limitations of energy consumption reduction and the increase in device cost.

[0040] Reference Figure 8 In one embodiment, the base station may further include: a second directional antenna and a second main antenna; The second directional antenna is used to: receive wireless radio frequency energy transmitted by the radio frequency module, transmit the wireless radio frequency energy to the communication component, and receive energy limit signals sent by the communication component, and send the energy limit signals to the radio frequency module; the energy limit signals include an upper energy limit signal and a lower energy limit signal. When the radio frequency module receives the upper energy limit signal, it stops transmitting wireless radio frequency energy to the second directional antenna, and when it receives the lower energy limit signal, it starts transmitting wireless radio frequency energy to the second directional antenna. The second main antenna is used to: receive downlink wireless data transmitted by the radio frequency module and transmit the downlink wireless data to the communication component, and receive uplink wireless data transmitted by the communication component and transmit the uplink wireless data to the radio frequency module.

[0041] Reference Figure 8 The base station also includes a main control chip and a power amplifier. The main control chip sends the processed baseband signal to the radio frequency module, which then converts the baseband signal into a radio frequency signal. On one hand, the RF module transmits the wireless RF energy of the RF signal to the power amplifier, which amplifies the wireless RF energy to ensure it can cover a longer distance, and then transmits the wireless RF energy to the second directional antenna, which in turn transmits the wireless RF energy to the communication component. When the RF module receives the energy limit signal sent by the communication component through the second directional antenna, it sends the signal to the main control chip. If the signal is the upper energy limit signal, the main control chip will control the RF module to stop transmitting wireless RF energy; if the signal is the lower energy limit signal, the main control chip will control the RF module to start transmitting wireless RF energy. On the other hand, the radio frequency module transmits the downlink wireless data of the radio frequency signal to the second main antenna in the form of an analog signal, so that the second main antenna can transmit the downlink wireless data to the communication component; after receiving the uplink wireless data in the form of an analog signal transmitted by the communication component, the second main antenna transmits it to the radio frequency module, which converts it into a baseband signal and then sends it to the main control chip for further processing.

[0042] In this embodiment, the base station adopts a dual-antenna mode. One antenna communicates with the radio frequency module through a power amplifier for wireless radio frequency power transmission and power limit signal transmission. The other antenna communicates directly with the radio frequency module for wireless data transmission, so that power transmission and data transmission do not interfere with each other, ensuring the stable operation of power transmission and data transmission. Furthermore, the received power limit signal controls the stopping and starting of wireless radio frequency power transmission, realizing efficient and controllable power supply.

[0043] In one embodiment, the radio frequency module can also be used for: In the first working mode, when the communication component is in a sleep state, downlink wireless data is buffered, and after receiving uplink wireless data transmitted by the communication component, downlink wireless data is transmitted to the communication component. That is, before receiving uplink wireless data transmitted by the communication component, the radio frequency module will not actively transmit downlink wireless data to the communication component in a sleep state. In the second working mode, when the communication component is in a sleep state, downlink wireless data is buffered, and after receiving uplink wireless data and data query requests sent by the communication component in sequence, downlink wireless data is transmitted to the communication component. That is, before receiving the data query request sent by the communication component, the radio frequency module will not actively transmit downlink wireless data to the communication component in a sleep state. In the third operating mode, it receives uplink wireless data transmitted by the communication component and transmits downlink wireless data to the communication component.

[0044] Based on the different data transmission states of the communication components, this embodiment designs three working modes from the radio frequency module side to cooperate with the communication components, respectively corresponding to the different power consumption and downlink communication link reliability of the communication components. This allows the communication components to select a suitable working mode in response to the continuous changes in downlink communication data volume requirements, thereby achieving a balance between downlink communication data volume requirements, communication component power consumption, and downlink communication link reliability.

[0045] In one embodiment, the radio frequency module can also be used for: In the first working mode, when the DC power level in the communication component is medium and the downlink communication data volume demand level is medium or high, the first working mode is switched to the second working mode; when the DC power level in the communication component is high and the downlink communication data volume demand level is medium or high, the first working mode is switched to the third working mode. In the second operating mode, when the DC power level in the communication component is high and the downlink communication data volume demand level is medium or high, the second operating mode is switched to the third operating mode; when the DC power level in the communication component is low, the second operating mode is switched to the first operating mode. In the third operating mode, when the DC power level in the communication component is medium, the third operating mode is switched to the second operating mode; when the DC power level in the communication component is low, the third operating mode is switched to the first operating mode.

[0046] This embodiment classifies the DC power consumption of the communication component and the downlink communication data volume requirement per unit time into different levels. This allows the radio frequency module to adaptively switch working modes with the communication component based on the different combinations of these two levels. This achieves a balance between downlink communication data volume requirement, communication component power consumption, and downlink communication performance, ensuring that the passive IoT communication component can work continuously without disconnection.

[0047] Figure 9 This is a schematic diagram of a wireless signal transmission system provided in an embodiment of this application. (Refer to...) Figure 9 This application provides a wireless signal transmission system, which may include: a communication component and a base station; The communication components include an energy harvesting module, an energy storage module, and a load module; An energy harvesting module is used to: collect radio frequency energy transmitted by a base station, convert the radio frequency energy into DC energy, and transmit the DC energy to the energy storage module; An energy storage module is used to store DC energy and transmit DC energy to a load module. Base stations include radio frequency modules; Radio frequency (RF) module, used to transmit wireless radio frequency energy to communication components.

[0048] Furthermore, the communication component may also include a first directional antenna and a first main antenna, and the base station may also include a main control chip, a power amplifier, a second directional antenna, and a second main antenna; The main control chip sends the processed baseband signal to the radio frequency module, which then converts the baseband signal into a radio frequency signal. On one hand, the radio frequency module transmits the radio frequency energy of the radio frequency signal to the power amplifier, the power amplifier amplifies the radio frequency energy, and then transmits the radio frequency energy to the second directional antenna, and the second directional antenna transmits the radio frequency energy to the first directional antenna; On the other hand, the radio frequency module transmits the downlink wireless data of the radio frequency signal to the second main antenna in the form of an analog signal, so that the second main antenna can transmit the downlink wireless data to the first main antenna; After receiving the radio frequency energy, the first directional antenna transmits it to the energy harvesting module. The energy harvesting module converts it into DC energy and transmits it to the energy storage module. The energy storage module stores the DC energy and then transmits it to the load module to power the load module. When the energy storage module reaches its energy storage limit, the energy harvesting module sends an energy limit trigger signal to the first directional antenna, which then transmits the signal to the second directional antenna. When the energy storage module reaches its energy storage lower limit, the energy harvesting module sends an energy lower limit trigger signal to the first directional antenna, which then transmits the signal to the second directional antenna. After receiving the downlink wireless data, the first main antenna transmits it to the load module for processing, and receives the uplink wireless data processed by the load module and transmits it to the second main antenna. After receiving the upper energy limit signal, the second directional antenna sends it to the radio frequency module through a power amplifier. The radio frequency module then sends it to the main control chip. After processing the signal, the main control chip controls the radio frequency module to stop transmitting wireless radio frequency energy. After receiving the lower energy limit signal, the second directional antenna sends it to the radio frequency module through a power amplifier. The radio frequency module then sends it to the main control chip. After processing the signal, the main control chip controls the radio frequency module to start transmitting wireless radio frequency energy. After receiving the uplink wireless data, the second main antenna transmits it to the radio frequency module. The radio frequency module processes the data and then transmits it to the main control chip for further processing.

[0049] In this embodiment, the communication component collects the radio frequency energy transmitted by the base station through its internal energy harvesting module, converts the radio frequency energy into DC energy, uses the DC energy to charge the internal energy storage module, and then transmits the stable DC energy to the load module through the energy storage module to power the load module. This allows the load module to avoid energy consumption caused by its own power supply, thereby reducing the overall energy consumption of the communication component. There is no need to shut down the communication component's process, nor is it necessary to use low-power devices as the communication load. Therefore, the energy consumption of the communication component can be reduced while avoiding the limitations of energy reduction and the increase in device cost.

[0050] Furthermore, both the base station and communication components adopt a dual-antenna design, with one antenna responsible for energy transmission and the other for data transmission. The energy transmission and data transmission processes can occur simultaneously without interference, ensuring the stability of both processes. Moreover, a closed-loop feedback mechanism for energy storage can be formed through an energy limit signal, avoiding energy waste while ensuring continuous power supply to the load module.
