[0058] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0059] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0060] The main solution of the embodiment of the present application is: when the current time is in a preset sleep period, the state control module outputs a first control signal to control the energy storage capacitor to discharge, and the discharge duration of the energy storage capacitor is consistent with the preset sleep period; the state control module outputs a sleep signal to the 5G RedCap module according to the remaining power of the energy storage capacitor during the discharge process; the 5GRedCap module switches the current state to the sleep state based on the sleep signal.

[0061] At present, the working principle of the 5G RedCap module is based on 5G lightweight technology, that is, by "functional tailoring" 5G technology to a certain extent, the complexity, cost, size and power consumption of terminals and modules can be reduced. This tailoring includes many aspects, such as reducing the maximum bandwidth, reducing antenna configuration, reducing the modulation order, and introducing half-duplex mode. Through these tailoring measures, the 5G RedCap module can meet the connection requirements of IoT devices at a lower cost and power consumption. Compared with other communication modules, the power consumption of the 5G RedCap module is relatively low. However, if the 5G RedCap module is in continuous and uninterrupted operation, monitoring the network's paging messages and data transmission, it will still increase its power consumption and affect the battery life.

[0062] The present application provides a circuit including a state control module, a 5G RedCap module and an energy storage capacitor. When the current time is in a preset sleep period, the state control module outputs a first control signal to control the energy storage capacitor to discharge, and the discharge duration of the energy storage capacitor is consistent with the preset sleep period; the state control module outputs a sleep signal to the 5G RedCap module according to the remaining power of the energy storage capacitor during the discharge process; the 5G RedCap module switches the current state to a sleep state based on the sleep signal. Since the discharge duration of the energy storage capacitor of the present application is consistent with the preset sleep period, the sleep signal can be continuously output during the preset sleep period through the remaining power of the energy storage capacitor during the discharge process, thereby maintaining the 5G RedCap module in a sleep state during the preset sleep period, effectively reducing the power consumption of the 5G RedCap module, and thus improving the battery life of the 5G RedCap module.

[0063] Based on this, the embodiment of the present application provides a circuit to reduce the power consumption of the 5G RedCap module, referring to Figure 1 , Figure 1 This is a structural schematic diagram of the first embodiment of the circuit for reducing the power consumption of the 5G RedCap module of the present application.

[0064] In this embodiment, the circuit includes: a state control module 100, a 5G RedCap module 200 and an energy storage capacitor C1.

[0065] The state control module 100 is connected to the 5G RedCap module 200 and the energy storage capacitor C1 respectively, and the energy storage capacitor C1 is connected to the 5G RedCap module 200 .

[0066] The state control module 100 is used to output a first control signal to control the energy storage capacitor C1 to discharge when the current time is in a preset sleep period, and the discharge duration of the energy storage capacitor C1 is consistent with the preset sleep period.

[0067] It should be noted that the first control signal may be a signal for triggering the discharge of the energy storage capacitor C1.

[0068] It is understandable that the preset sleep period can be a period of time that the 5G RedCap module 200 is required to enter the sleep state, such as 10 seconds. The period outside the preset sleep period can be a period of time that the 5G RedCap module 200 is required to enter the wake-up state, such as 10 seconds.

[0069] It should be noted that the above-mentioned 5G RedCap module 200 can be a module with a wake-up state and a sleep state, and can receive a low-level signal to enter the sleep state, and receive a high-level signal to enter the wake-up state, such as the YWM100 module.

[0070] In the specific implementation, refer to Figure 2 , Figure 2 This is a schematic diagram of the time period in the first embodiment of the present application. The operation cycle can be pre-configured. The operation cycle is composed of T1 (preset sleep period) and T2 (preset wake-up period) alternately. The preset wake-up period is a period outside the pre-sleep period. When the current time enters the TI period, the required 5G RedCap module 200 enters a low-power sleep state. When the current time enters the T2 period, the required 5G RedCap module 200 enters a high-power wake-up state. The above-mentioned state control module 100 can periodically detect whether the current time is in the preset sleep period. In addition, a discharge circuit may be provided in the above-mentioned state control module 100. When it is detected that the current state is in a preset sleep period, the discharge circuit may be activated by a first control signal, and the energy storage capacitor C1 may be connected to the discharge circuit so that the energy storage capacitor C1 is discharged through the discharge circuit. At the same time, the parameters of the discharge circuit may be configured so that the discharge duration of the energy storage capacitor C1 is consistent with the preset sleep period, or, within the preset sleep period, the first control signal is continuously output for a duration. When the preset sleep period is exceeded, the first control signal is stopped from being output, so as to ensure that the discharge duration of the energy storage capacitor C1 is consistent with the preset sleep duration.

[0071] The state control module 100 is further configured to output a sleep signal to the 5G RedCap module 200 according to the remaining power of the energy storage capacitor C1 during the discharge process.

[0072] In a specific implementation, a switch device may be provided in the state control module 100, one end of which is connected to the 5G RedCap module 200 and the other end is grounded. During the discharge process of the energy storage capacitor C1, the residual power forms a current that flows to the discharge circuit and the state control module 100 respectively. The state control module 100 can receive the voltage generated by the residual power of the energy storage capacitor C1 to drive the switch device to close, ground the 5G RedCap module 200, and output the low-level sleep signal generated by the grounding to the 5G RedCap module 200.

[0073] The 5G RedCap module 200 is used to switch the current state to the sleep state based on the sleep signal.

[0074] In a specific implementation, the above-mentioned low-level sleep signal can be used as a signal to trigger the 5G RedCap module 200 to enter a sleep state. When the 5G RedCap module 200 receives the sleep signal, it can turn off its own circuits related to data transmission and enter a sleep state. In the sleep state, the 5G RedCap module 200 cannot actively send or receive data, so the power consumption of the 5G RedCap module 200 in the sleep state is low, which helps the 5G RedCap module 200 to maintain low power consumption for a long time. In addition, some simple data caching or pre-processing functions may be in normal operation so that the 5G RedCap module 200 can process data quickly when it wakes up.

[0075] It should be understood that when the 5G RedCap module 200 is in sleep mode, if it receives data and the data type is a pre-configured type, such as a network configuration type or a higher priority type, it can immediately wake up and process the data to ensure that the 5G RedCap module 200 can respond to changes in the network in a timely manner or meet the real-time requirements of data transmission.

[0076] It should be noted that since the discharge time of the energy storage capacitor C1 is consistent with the preset sleep period, that is, the discharge time is equal to the time corresponding to the preset sleep period, therefore, during the preset sleep period, a sleep signal can be continuously output to keep the 5G RedCap module 200 in sleep state during the preset sleep period.

[0077] It is understandable that when the state control module 100 detects that the preset sleep period has not been entered, or the preset wake-up period has been entered from the preset sleep period, it can output a corresponding signal to control the 5G RedCap module 200 to exit the sleep state and enter the wake-up state.

[0078] Furthermore, by configuring an operating cycle consisting of alternating preset sleep periods and preset wake-up periods, and the duration of the preset sleep periods and the preset wake-up periods can be configured to be lower than a set duration, the settable duration can be set shorter, such as 10s, so that the 5G RedCap module 200 can continuously undergo multiple wake-up and sleep cycles. Since the preset sleep period is short, it is possible to minimize the power consumption of the device while ensuring data transmission requirements.

[0079] The circuit for reducing the power consumption of the 5G RedCap module provided in this embodiment includes a state control module, a 5G RedCap module and an energy storage capacitor. When the current time is in a preset sleep period, the state control module outputs a first control signal to control the energy storage capacitor to discharge, and the discharge duration of the energy storage capacitor is consistent with the preset sleep period; the state control module outputs a sleep signal to the 5G RedCap module according to the remaining power of the energy storage capacitor during the discharge process; the 5G RedCap module switches the current state to a sleep state based on the sleep signal. Since the discharge duration of the energy storage capacitor of the present application is consistent with the preset sleep period, the sleep signal can be continuously output during the preset sleep period through the remaining power of the energy storage capacitor during the discharge process, so that the 5G RedCap module is kept in a sleep state during the preset sleep period, which effectively reduces the power consumption of the 5G RedCap module, thereby improving the battery life of the 5G RedCap module.

[0080] Based on the first embodiment of the present application, the second embodiment of the present application is proposed. In the second embodiment of the present application, the same or similar contents as those of the first embodiment can be referred to the above introduction, and will not be repeated later. Figure 3 , Figure 3 This is a structural schematic diagram of the second embodiment of the circuit for reducing the power consumption of the 5G RedCap module of the present application.

[0081] In this embodiment, the state control module 100 includes: a control chip and a discharge module 101;

[0082] The discharge module 101 is connected to the control chip, the energy storage capacitor C1 and the 5G RedCap module 200 respectively.

[0083] The control chip is used to output the first control signal to conduct the discharge circuit between the energy storage capacitor C1 and the discharge module 101 when the current time is in the preset sleep period.

[0084] like Figure 4 As shown, Figure 4 4 is a circuit diagram of a discharge module in the second embodiment of the present application. Figure 4 In the embodiment, the discharge module 101 includes: a first switch tube Q1 and a first resistor R1.

[0085] The control end of the first switch tube Q1 is connected to the first pin VIN1 of the control chip, the input end of the first switch tube Q1 is connected to the first end of the energy storage capacitor C1, the output end of the first switch tube Q1 is connected to the first end of the first resistor R1, and the second end of the first resistor R1 and the second end of the energy storage capacitor C1 are both grounded GND.

[0086] In a specific implementation, the first switch tube is illustrated by taking a PMOS tube as an example. When the above-mentioned control chip is in a preset sleep period at the current time, the first pin VIN1 of the control chip can output a low-level first control signal to the gate of the first switch tube Q1, thereby controlling the first switch tube Q1 to close and turning on the discharge circuit formed by the energy storage capacitor C1 and the first resistor R1.

[0087] The energy storage capacitor C1 is used to output a voltage corresponding to the current stored electricity to the discharge module 101 through the discharge circuit for discharge.

[0088] In a specific implementation, the energy storage capacitor C1 can output a corresponding voltage to the first resistor R1 based on the current stored electricity stored in the capacitor, that is, the energy storage capacitor C1 releases the current stored electricity stored in the capacitor through the first resistor to achieve discharge.

[0089] In this embodiment, the state control module 100 further includes: a sleep control module 102 .

[0090] Reference Figure 5 , Figure 5 Schematic diagram of the structure of the sleep control module in the second embodiment of the present application. Figure 5 In the embodiment, the sleep control module 102 is respectively connected to the 5G RedCap module 200, the control chip and the energy storage capacitor C1.

[0091] The control chip is further configured to connect the energy storage capacitor C1 to the sleep control module 102 through the first control signal.

[0092] In a specific implementation, the first pin VIN1 of the control chip can output a first control signal to the sleep control module 102 , thereby switching on the loop between the sleep control module 102 and the energy storage capacitor C1 , and connecting the energy storage capacitor C1 to the sleep control module 102 .

[0093] like Figure 6 As shown, Figure 6 This is a circuit schematic diagram of the sleep control module in the second embodiment of the present application. Figure 6In the embodiment, the sleep control module 102 includes: a second switch tube Q2, a third switch tube Q3 and a second resistor R2.

[0094] The control end of the second switch tube Q2 is connected to the first pin VIN1 of the control chip, the input end of the second switch tube Q2 is connected to the first end of the energy storage capacitor C1, the output end of the second switch tube Q2 is connected to the first end of the second resistor R2, the control end of the third switch tube Q3 is connected to the first end of the second resistor R2, the input end of the third switch tube Q3 is connected to the 5G RedCap module 200, and the output end of the third switch tube Q3 is grounded GND.

[0095] It should be noted that the second switch tube Q2 is exemplified by a PMOS tube. When the control chip is in a preset sleep period at the current time, the first pin VIN1 of the control chip can output a low-level first control signal to the gate of the second switch tube Q2, controlling the second switch tube Q2 to close and connect the energy storage capacitor C1 to the second resistor R2.

[0096] The energy storage capacitor C1 is further used to output a capacitor voltage corresponding to the remaining power to the sleep control module 102 when connected to the sleep control module 102 .

[0097] In the specific implementation, continue to refer to Figure 6 , taking a PMOS tube as an example of the second switch tube Q2. After receiving the low-level first control signal, the second switch tube Q2 is closed, and the energy storage capacitor C1 is connected to the second resistor R2. The capacitor voltage corresponding to the remaining power of the energy storage capacitor C1 can be output to the third switch tube Q3 through the second resistor R2.

[0098] The sleep control module 102 is used to turn on the ground loop of the 5G RedCap module 200 when the capacitor voltage is not lower than a preset voltage threshold, so that a low-level sleep signal is input to the 5G RedCap module 200 .

[0099] It should be noted that the above-mentioned preset voltage threshold may be the conduction threshold of the third switch tube Q3.

[0100] In the specific implementation, continue to refer to Figure 6, taking the PMOS tube as an example for the second switch tube Q2, and the NMOS tube as an example for the third switch tube Q3. The capacitor voltage corresponding to the remaining power of the energy storage capacitor C1 can be output to the gate of the third switch tube Q3 through the second resistor R2. When the capacitor voltage is not lower than the preset voltage threshold, that is, greater than or equal to the preset voltage threshold, the third switch tube Q3 is closed, and the 5G RedCap module 200 is grounded to GND, that is, the grounding loop of the 5G RedCap module 200 is turned on, so that the low-level sleep signal is input to the 5G RedCap module 200.

[0101] In this embodiment, the control chip turns on the discharge loop between the energy storage capacitor and the discharge module through the first control signal, so that the energy storage capacitor is discharged through the discharge module. At the same time, the control chip connects the energy storage capacitor to the sleep control module through the first switch signal. When the energy storage module is connected to the sleep control module, it outputs the capacitor voltage corresponding to the remaining power to the sleep control module. When the capacitor voltage is not lower than the preset voltage threshold, the ground loop of the 5G RedCap module is turned on, so that the low-level sleep signal can be accurately input to the 5G RedCap module, thereby improving the accuracy of switching the 5G RedCap module to the sleep state.

[0102] Based on the first and second embodiments of the present application, the third embodiment of the present application is proposed. In the third embodiment of the present application, the same or similar contents as those of the first and second embodiments can be referred to the above introduction, and will not be repeated later. Figure 7 , Figure 7 This is a schematic diagram of the structure of the third embodiment of the circuit for reducing the power consumption of the 5G RedCap module of the present application.

[0103] In this embodiment, the state control module 100 further includes: a charging module 103 .

[0104] The charging module 103 is connected to the control chip, the energy storage capacitor C1 and the first power supply module VCC1 respectively.

[0105] The control chip is further configured to output a second control signal to the charging module 103 when the current time is not in the preset sleep period.

[0106] In a specific implementation, when the control chip is not in a preset sleep period, that is, in a preset wake-up period at the current time, the second pin VIN2 of the control chip can output a second control signal to the charging module 103 .

[0107] The charging module 103 is used to conduct the charging circuit between the first power module VCC1 and the energy storage capacitor C1 according to the second control signal.

[0108] The first power module VC1 is used to charge the energy storage capacitor C1 according to the charging circuit.

[0109] In a specific implementation, the charging module 103 may be composed of a plurality of switch devices, and the second pin VIN2 of the control chip may output a second control signal to the control end of the switch device to close the switch device and conduct the charging circuit between the first power module VCC1 and the energy storage capacitor C1.

[0110] like Figure 8 As shown, Figure 8 This is a circuit diagram of a charging module in the third embodiment of the present application. Figure 8 In the embodiment, the charging module 103 includes a fourth switch tube Q4 and a fifth switch tube Q5.

[0111] The control end of the fourth switch tube Q4 is connected to the second pin VIN2 of the control chip, the input end of the fourth switch tube Q4 is connected to the control end of the fifth switch tube Q5, the output end of the fourth switch tube Q4 is grounded GND, the input end of the fifth switch tube Q5 is connected to the first power module VCC1, and the output end of the fifth switch tube Q5 is connected to the first end of the energy storage capacitor C1.

[0112] It should be noted that the fourth switch tube Q4 is exemplified by an NMOS tube, and the fifth switch tube Q5 is exemplified by a PMOS tube.

[0113] In this embodiment, the state control module further includes: a wake-up control module 104 .

[0114] Reference Fig. 9 , Fig. 9 This is a structural diagram of the wake-up control module in the third embodiment of the present application. The wake-up control module 104 is respectively connected to the control chip, the 5G RedCap module 200 and the second power module VCC2.

[0115] The control chip is further configured to output the second control signal to the wake-up control module 104 when the current time is not in the preset sleep period.

[0116] In a specific implementation, when the current time is not in the preset sleep period, that is, when the control chip is in the preset wake-up period, the second pin VIN2 of the control chip can output a second control signal to the wake-up control module 104, and the wake-up control module 104 switches the current state of the 5G RedCap module 200 to the wake-up state.

[0117] The wake-up control module 104 is used to connect the 5G RedCap module 200 to the second power module VCC2 according to the second control signal.

[0118] The second power module VCC2 is used to output a high-level wake-up signal to the 5G RedCap module 200 when connected to the 5G RedCap module 200.

[0119] The 5G RedCap module 200 is used to switch the current state to the awake state based on the awake signal.

[0120] like Fig.10 As shown, Fig.10 This is a circuit schematic diagram of the wake-up control module in the third embodiment of the present application. Fig.10 In the embodiment, the sixth switch tube Q6, the seventh switch tube Q7, the third resistor R3 and the fourth resistor R4.

[0121] The control end of the sixth switch tube Q6 is connected to the second pin VIN2 of the control chip, the input end of the sixth switch tube Q6 is connected to the second power module VCC2, the output end of the sixth switch tube Q6 is connected to the first end of the third resistor R3, the second end of the third resistor R3 is connected to the input end of the fourth switch tube Q4, the control end of the seventh switch tube Q7 is connected to the input end of the fourth switch tube Q4, the input end of the seventh switch tube Q7 is connected to the first end of the fourth resistor R4, the second end of the fourth resistor R4 is connected to the second power module VCC2, and the output end of the seventh switch tube Q7 is connected to the 5G RedCap module 200.

[0122] In the specific implementation, the sixth switch tube Q6 is exemplified by the NOMS tube, and the seventh switch tube Q7 is exemplified by the PMOS tube. When the above-mentioned control chip is not in the preset sleep period at the current time, that is, when it is in the preset wake-up period, the second pin VIN2 of the control chip can output a low-level second control signal to the gate of the sixth switch tube Q6, so that the sixth switch tube Q6 is closed, the gate of the seventh switch tube Q7 is grounded, and the low-level signal is input to the gate of the seventh switch tube Q7, so that the seventh switch tube Q7 is closed, and the loop between the second power module VCC2, the fourth resistor R4 and the 5G RedCap module 200 is turned on, and the 5G RedCap module 200 is connected to the second power module VCC2. The second power supply VCC2 can output its own power supply voltage to the 5G RedCap module 200 through the fourth resistor R4, and the power supply voltage output by the second power supply VCC2 can be a high-level wake-up signal. When the 5G RedCap module 200 receives the wake-up signal, it can restore its own circuit related to data transmission and enter the wake-up state. When awake, the 5G RedCap module 200 is active and can actively send or receive data and perform various communication tasks.

[0123] When the control chip of this embodiment is not in the preset sleep period at the current time, it outputs a second control model to the wake-up control module. The wake-up control module connects the 5G RedCap module to the second power module according to the second control model. The second power module outputs a high-level wake-up signal to control the 5G RedCap module to switch the current state to the wake-up state, thereby accurately switching the 5G RedCap module to the sleep state.
