[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] The terms "including" and "having" in the embodiments of the present application are used to express an open-ended inclusive meaning, and mean that in addition to the listed elements / components / etc., there may be additional elements / components / etc.; the terms "first" and "second" etc. are used only as labels and are not intended to limit the quantity of their objects. In addition, the different elements and regions in the drawings are only schematically shown, so the present application is not limited to the sizes or distances shown in the drawings.

[0057] At present, when the power supply equipment is in low power during use, the remaining power cannot drive the equipment to continue to operate, resulting in waste of the remaining power and reducing the efficiency of product use.

[0058] For the currently emerging human embedded devices, they are embedded in the human body to achieve the purpose of detection or treatment. There is also the problem of low utilization rate of the remaining power of the device. When the power of the embedded device is lower than the starting power of the surrounding functional modules, the battery power supply can no longer support the normal operation of the functional modules. Therefore, the power supply control needs to be started again based on the remaining power. Frequent charging and discharging will affect the service life of the device.

[0059] In order to further improve the utilization rate of the remaining power and improve the power supply efficiency of the equipment, the present application proposes a power supply delay circuit. On the premise of using the first power supply module and the second power supply module to power the subsequent excitation source, a delay selection module is added. When the remaining power of the power supply battery module is insufficient to power the subsequent excitation source, the voltage of the power supply battery module is boosted by switching the second power supply module to the delay selection module, and the boosted electric energy continues to power the subsequent excitation source, thereby improving the power supply efficiency.

[0060] To facilitate understanding of the embodiments of the present application, further explanation will be given below with reference to specific embodiments in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present application.

[0061] Figure 1 A schematic diagram of a power supply delay circuit provided in an embodiment of the present application. Figure 1 The diagram provided shows that the structure of the power supply delay circuit specifically includes:

[0062] A power supply battery module 10 , a main controller MCU, a first power supply module 20 , a second power supply module 30 and a delay selection module 40 .

[0063] The first output end of the power supply battery module 10 is connected to the input end of the first power supply module 20, the first input end of the second power supply module 30 and the first input end of the delay selection module 40, the second output end of the power supply battery module 10 is connected to the first input end of the main controller MCU, the input end of the power supply battery module 10 is connected to the first output end of the delay selection module 40 and the first output end of the second power supply module 30, and the power supply battery module 10 is used to provide electrical energy to the main controller MCU, the first power supply module 20, the second power supply module 30 and the delay selection module 40.

[0064] The second input end of the main controller MCU is connected to the second output end of the delay selection module 40, the first output end of the main controller MCU is connected to the second input end of the second power supply module 30, the second output end of the main controller MCU is connected to the second input end of the delay selection module 40, and the third output end of the main controller MCU is connected to the third input end of the delay selection module 40. The main controller MCU is used to determine the current power level of the power supply battery module 10. When the power level is lower than the power supply level of the subsequent circuit, the delay selection module 40 is controlled to boost the voltage. At the same time, when the power level is higher than the power supply level of the subsequent circuit, the second power supply module 30 is controlled to supply power to the subsequent excitation source.

[0065] The output end of the first power supply module 20 is connected to the output end of the first power supply VDD1 , and the first power supply module 20 is used to supply power to the external functional circuit through the output end of the first power supply VDD1 .

[0066] The second output end of the second power supply module 30 and the third output end of the delay selection module 40 are connected to the second power supply output end. The second power supply module 30 is used to power the subsequent stage excitation source connected to the output end of the second power supply VDD2 when the power of the power supply battery module 10 meets the set requirements. The delay selection module 40 is used to power the subsequent stage excitation source connected to the output end of the second power supply VDD2 when the power of the power supply battery module 10 does not meet the set requirements.

[0067] Exemplarily, when the main controller MCU detects that the remaining power of the power supply battery module exceeds the set value, it means that the power of the current power supply battery module 10 is sufficient to drive the subsequent excitation source circuit. The power supply battery module 10 outputs electric energy to the first power supply module 20, and the first power supply module 20 directly supplies power to the external functional circuit through the output end of the first power supply VDD1 to ensure that the devices in the circuit remain in the startup state. For example, the main controller MCU is directly powered by the first power supply VDD1, and the main controller MCU is started internally to ensure that the internal functional modules of the power supply delay circuit are powered normally. Similarly, the second power supply module is powered by the power supply battery module 10, and the internal conduction of the second power supply module is controlled by the main controller MCU to ensure that the second power supply module supplies electric energy to the subsequent excitation source through the output end of the second power supply VDD2.

[0068] Furthermore, when the main controller MCU detects that the remaining power of the power supply battery module 10 is insufficient and is lower than the set minimum value, in order to improve the utilization rate of the remaining power and extend the service life of the power supply battery module, the main controller MCU controls the internal disconnection of the second power supply module to cut off the second power supply module from continuing to supply power to the subsequent excitation source. At the same time, the main controller MCU controls the internal connection of the delay selection module 40, and a low voltage is input to the delay selection module 40 through the power supply battery module 10. After the internal boost processing of the delay selection module 40, a high voltage is output. The main controller MCU detects in real time whether the high voltage output by the delay selection module 40 reaches the power supply voltage of the subsequent excitation source. When the high voltage rises to the power supply voltage of the subsequent excitation source, the delay selection module 40 supplies power to the subsequent excitation source, thereby enabling the power supply battery module 10 to extend the power supply time when the remaining power is insufficient and improve the power supply efficiency.

[0069] The power supply delay circuit provided in the embodiment of the present application is provided with a power supply battery module, a main controller, a first power supply module, a second power supply module and a delay selection module; the first output end of the power supply battery module is connected to the input end of the first power supply module, the first input end of the second power supply module and the first input end of the delay selection module, the second output end of the power supply battery module is connected to the first input end of the main controller, the input end of the power supply battery module is connected to the first output end of the delay selection module and the first output end of the second power supply module, and the power supply battery module is used to provide electric energy to the main controller, the first power supply module, the second power supply module and the delay selection module; the second input end of the main controller is connected to the second output end of the delay selection module, the first output end of the main controller is connected to the second input end of the second power supply module, and the second output end of the main controller is connected to the second input end of the delay selection module , the third output terminal of the main controller is connected to the third input terminal of the delay selection module, the main controller is used to judge the current power of the power supply battery module, when the power is lower than the power supply of the subsequent circuit, the delay selection module is controlled to boost the voltage, and when the power is higher than the power supply of the subsequent circuit, the second power supply module is controlled to supply power to the subsequent excitation source; the output terminal of the first power supply module is connected to the first power supply output terminal, the first power supply module is used to supply power to the external functional circuit through the first power supply output terminal; the second output terminal of the second power supply module is connected to the third output terminal of the delay selection module, the second power supply module is used to supply power to the subsequent excitation source connected to the second power supply output terminal when the power of the power supply battery module meets the set requirements, and the delay selection module is used to supply power to the subsequent excitation source connected to the second power supply output terminal when the power of the power supply battery module does not meet the set requirements. By detecting the remaining power of the power supply battery module, the delay selection module is started when the remaining power is low, the second power supply module is turned off, and the delay selection module is used to perform voltage boost processing to achieve the purpose of continuing to supply power to the subsequent excitation source, which can achieve the technical effect of increasing the power supply time of the battery and increasing the battery life.

[0070] Figure 2 A schematic diagram of the structure of another power supply delay circuit provided in an embodiment of the present application. Figure 2 This is introduced based on the previous embodiment. Figure 2 The diagram provided shows that the structure of the power supply delay circuit specifically includes:

[0071] A power supply battery module 10 , a main controller MCU, a first power supply module 20 , a second power supply module 30 and a delay selection module 40 .

[0072] according to Figure 2 According to the provided diagram, the power supply delay circuit further includes: a first diode D1.

[0073] The forward output end of the first diode D1 and the output end of the first power supply module 20 are connected to the output end of the first power supply VDD1, and the reverse input end of the first diode D1 and the second output end of the second power supply module 30 and the third output end of the delay selection module 40 are connected to the output end of the second power supply VDD2. The first diode D1 is used to supply power to the output end of the first power supply VDD1 through the delay selection module 40 when the power of the power supply battery module 10 does not meet the set requirements.

[0074] Exemplarily, when the power of the power supply battery module is sufficient (for example, the power threshold is set to 15%), power is supplied to the external functional circuit through the first power supply module and the output end of the first power supply VDD1. At the same time, power is supplied to the subsequent excitation source through the second power supply module and the output end of the second power supply VDD2. At this time, due to the unidirectional conductivity of the first diode, when the voltages of the output ends of VDD1 and VDD2 are set the same, the potentials at both ends of the first diode are equal. When the power supply battery module is supplying power normally, the first diode remains in a non-conducting state, blocking the second power supply module from supplying power to the external functional circuit through the first power supply VD1. When it is detected that the remaining power of the power supply battery module is less than 15%, which is insufficient to continue to supply power to the subsequent excitation source, the second power supply module is cut off to continue to supply power to the subsequent excitation source, and the delay selection module 40 is internally turned on, and the low voltage output by the power supply battery module is boosted by the delay selection module to output a high voltage, and the delay selection module and the second power supply VDD2 are used to supply power to the subsequent excitation source. At this time, the first power supply module 20 does not work. Since the delay selection module 40 boosts the input voltage, and the boosted voltage reaches the supply voltage of the subsequent excitation source, the delay selection module 40 and the second power supply VDD2 are used to supply power to the subsequent excitation source. At this time, the output terminal voltage of the first power supply module is higher than the input terminal voltage, so that the first power supply module 20 does not work, and the first diode D1 is turned on at the same time, and the high-level voltage output by the delay selection module 40 is input to the first power supply VDD1 through the first diode D1 to continue to supply power to the external functional circuit, ensuring that the power supply battery module 10 continues to supply power when the remaining power is insufficient, further improving the utilization rate of the remaining power, and achieving the purpose of delayed power supply.

[0075] according to Figure 2 According to the provided diagram, the power supply battery module 10 in the power supply delay circuit includes: a power supply battery By, a first capacitor C1, a first impedance R1 and a second impedance R2.

[0076] The positive output end of the power supply battery By is connected to one end of the first capacitor C1, one end of the first impedance R1, the input end of the first power supply module 20, the first input end of the second power supply module 30 and the first input end of the delay selection module 40 as the first output end of the power supply battery module 10. The negative input end of the power supply battery By is connected to the ground end as the input end of the power supply battery module 10 and the other end of the first capacitor C1, one end of the second impedance R2, the first output end of the delay selection module 40 and the first output end of the second power supply module 30. The power supply battery By is used to supply power to the first power supply module 20, the second power supply module 30 and the delay selection module 40. The power supply battery By is also used to feedback the current power to the main controller MCU, so that the main controller MCU selects whether to turn on the delay selection module 40 to power the subsequent excitation source according to the current power.

[0077] The other end of the first impedance R1 is connected to the first input end of the main controller MCU and the other end of the second impedance R2 as the second output end of the power supply battery module 10. The first impedance R1 and the second impedance R2 are used to feed back the remaining power of the current power supply battery to the main controller MCU.

[0078] Exemplarily, the main controller MCU detects the potential between the first impedance R1 and the second impedance R2 in real time, and then calculates the remaining power of the current power supply battery By. When it is detected that the remaining power exceeds the set minimum power supply power (for example, 10%w is set as the minimum power), the first power supply module 20 and the second power supply module 30 continue to supply power to the subsequent circuit; when it is detected that the remaining power is less than 10% of the minimum power supply power, in order to ensure that the subsequent excitation source continues to operate, it is necessary to cut off the first power supply module 20 and the second power supply module 30, and use the delay selection module 40 to supply power to the subsequent circuit, and the input low voltage is boosted by the delay selection module 40 to output a high-level voltage to reach the operating voltage of the subsequent circuit, and continue to supply power to the subsequent circuit through the first power supply VDD1 and the second power supply VDD2.

[0079] according to Figure 2 According to the provided diagram, the first power supply module 20 in the power supply delay circuit includes: a second diode D2.

[0080] The reverse input end of the second diode D2 is connected to the first output end of the power supply battery module 10, the first input end of the second power supply module 30 and the first input end of the delay selection module 40 as the input end of the first power supply module 20, and the forward output end of the second diode D2 is connected to the output end of the first power supply VDD1 as the output end of the first power supply module 20. The second diode D2 is used to provide the electric energy output by the power supply battery module 10 to the external functional circuit through the output end of the first power supply VDD1. The second diode D2 is also used to block the first power supply VDD1 from reverse charging the power supply battery module 10 when the output end voltage of the first power supply VDD1 exceeds the output voltage of the power supply battery module 10.

[0081] according to Figure 2The diagram provided shows that when the main controller MCU detects that the remaining power of the power supply battery module 10 exceeds the set minimum power supply power (for example, exceeds 15% of the total power), the power supply battery module 10 is directly transmitted to the output end of the first power supply VDD1 through the second diode D2 in the first power supply module 20, and the power supply battery module 10 supplies power to the external functional circuit through the second diode D2, for example, to keep supplying power to the main controller MCU, so as to ensure that the main controller MCU is always turned on. At the same time, the second power supply module 30 is used to supply power to the subsequent excitation source. When the main controller MCU detects that the remaining power of the power supply battery module 10 is insufficient, the second power supply module 30 is blocked from continuing to supply power to the subsequent excitation source, and the delay selection module 40 is used to replace the second power supply module 30. The low voltage is boosted by the delay selection module 40 to increase the output voltage of the power supply battery module 10. When the output voltage of the delay selection module 40 is increased to the power supply size of the subsequent excitation source, the purpose of using the remaining power of the power supply battery module 10 to continue to supply power to the subsequent excitation source can be achieved.

[0082] Furthermore, when the output voltage of the first diode D1 is higher than the input voltage of the second diode D2, the second diode D2 is not turned on, and the first power supply module 20 does not work. At this time, the first diode D1 is connected to the first power supply VDD1 to supply power to the external functional circuit, ensuring that the external functional circuit is always running.

[0083] according to Figure 2 According to the provided diagram, the delay selection module 40 in the power supply delay circuit includes: a first switch relay S1, a second capacitor C2, a first inductor L1, a third diode D3, a first transistor Q1, a third impedance R3, a fourth impedance R4 and a third capacitor C3.

[0084] The control end of the first switch relay S1 is connected to the second output end of the main controller MCU as the second input end of the delay selection module 40, the first end of the first switch relay S1 is connected to the input end of the first power supply module 20, the first output end of the power supply battery module 10 and the first input end of the second power supply module 30 as the first input end of the delay selection module 40, the second end of the first switch relay S1 and one end of the second capacitor C2 and one end of the first inductor L1 are connected to the first node Vi, the first switch relay S1 is used for the main controller MCU to determine whether to start delayed power supply according to the remaining power of the current power supply battery module 10, when the main controller MCU chooses to start delayed power supply, the main controller MCU controls the first switch relay S1 to keep in a closed state, and when the delayed power supply is not turned on, the main controller MCU controls the first switch relay S1 to keep in an open state.

[0085] The other end of the second capacitor C2 serves as the first output end of the delay selection module 40 and is connected to the input end of the power supply battery module 10, the first end of the first transistor Q1, one end of the fourth impedance R4, one end of the third capacitor C3 and the first output end of the second power supply module 30.

[0086] The other end of the first inductor L1 is connected to the reverse input end of the third diode D3 and the second end of the first transistor Q1 .

[0087] The forward output end of the third diode D3 is connected as the third output end of the delay selection module 40 to the second node Vo together with one end of the third impedance R3, the other end of the third capacitor C3, the second output end of the second power supply module 30 and the output end of the second power supply VDD2.

[0088] The control end of the first transistor Q1 is connected to the third output end of the main controller MCU as the third input end of the delay selection module 40 .

[0089] The other end of the third impedance R3 is connected to the other end of the fourth impedance R4 and the second input end of the main controller MCU as the second output end of the delay selection module 40 .

[0090] Exemplarily, the first transistor can be understood as a transistor with a switch function, such as a MOS tube, a triode or an IGBT, etc. The control end of the transistor in this embodiment is the gate of the MOS tube, the first end of the transistor is the source of the MOS tube, and the second end of the transistor is the drain of the MOS tube.

[0091] according to Figure 2The diagram provided shows that when the main controller MCU detects that the remaining power of the power supply battery module 10 exceeds the set minimum power supply power (15% is set as the minimum power supply threshold), the first switch relay S1 is controlled to be disconnected, and power is supplied to the subsequent circuit through the first power supply module 20 and the second power supply module 30. When the main controller MCU detects that the remaining power of the power supply battery module 10 is lower than 15% of the set minimum power supply power, the main controller MCU blocks the second power supply module 30 from continuing to supply power to the subsequent excitation source. At the same time, the first switch relay S1 is controlled to be turned on, and the first transistor Q1 is turned on to store energy for the first inductor L1. When the first transistor Q1 is controlled to be disconnected, the first inductor L1 is used to store energy and filter for the second capacitor C2. On the basis of the unidirectional conductivity of the third diode D3, the reverse current is prevented from flowing back to protect the power supply battery module 10. The low voltage at the input end is detected at the first node Vi, and then the voltage at the second node Vo is increased after energy storage and filtering through the third capacitor C3 at the output end. The voltage at the second node Vo is calculated by the main controller MCU in real time detecting the voltage division between the third impedance and the fourth impedance. When the voltage difference between the second node Vo and Vi rises to the power supply voltage of the subsequent excitation source, the subsequent excitation source is powered by the voltage at the second node Vo and the second power supply VDD2, ensuring that power is continued to be supplied to the subsequent circuit when the power supply battery module 10 is low on power.

[0092] according to Figure 2 According to the provided diagram, the second power supply module 30 in the power supply delay circuit includes: a second switch relay S2, a fourth diode D4 and a fourth capacitor C4.

[0093] The control end of the second switch relay S2 is connected to the first output end of the main controller MCU as the second input end of the second power supply module 30, the first end of the second switch relay S2 is connected to the first output end of the power supply battery module 10, the input end of the first power supply module 20 and the first input end of the delay selection module 40 as the first input end of the second power supply module 30, and the second end of the second switch relay S2 is connected to the reverse input end of the fourth diode D4.

[0094] The forward output end of the fourth diode D4 is connected as the second output end of the second power supply module 30 to one end of the fourth capacitor C4, the third output end of the delay selection module 40 and the output end of the second power supply VDD2;

[0095] The other end of the fourth capacitor C4 is connected to the first output end of the delay selection module 40 and the input end of the power supply battery module 10 as the first output end of the second power supply module 30 .

[0096] The first switch relay and the second switch relay mentioned here are the same kind of devices, both of which are relays or switches with switching functions.

[0097] Exemplarily, when the main controller MCU detects that the remaining power of the power supply battery module 10 exceeds the set minimum power supply power, it indicates that the current power supply battery module 10 can continue to supply power to the subsequent circuit. The main controller MCU controls the second switch relay S2 to remain in the on state, and the electric energy output by the power supply battery module 10 is output to the second power supply VDD2 through the fourth diode D4 to supply power to the subsequent excitation source. When the main controller MCU detects that the remaining power of the power supply battery module 10 is insufficient, the main controller MCU controls the second switch relay S2 to remain disconnected, cuts off the second power supply module 30 from continuing to supply power to the subsequent excitation source, and changes to the internal connection of the delay selection module 40, and the low voltage output by the power supply battery module 10 is boosted to a high voltage through the delay selection module 40, and output to the second power supply VDD2. When the main controller MCU detects that the output high voltage reaches the power supply voltage of the subsequent excitation source, the purpose of the delay selection module 40 supplying power to the subsequent excitation source is achieved, thereby making full use of the remaining power of the power supply battery module 10 and improving the power supply efficiency.

[0098] according to Figure 2 The diagram provided shows that in a possible example scenario, when the power supply battery By is in a normal power supply state (the normal power supply range is generally set to 2.5V-5V), the electric energy is output to the first power supply VDD1 through the first power supply module, and the first power supply VDD1 is used to power the main controller MCU and other devices. At the same time, during the entire operation process, the first power supply VDD1 is always kept to power the main controller MCU, that is, the first power supply module is a functional module that cannot be powered off. At the same time, the first power supply VDD1 is also connected to an external communication circuit, such as a wireless connection network and other functional circuits, to ensure that the device communicates with the outside world.

[0099] Furthermore, the main controller MCU starts working after power is supplied, controls the second switch relay S2 to be turned on, so that the voltage of the power supply battery is output to the second power supply VDD2 after voltage division and current limiting, and supplies power to the subsequent stimulation source through the second power supply VDD2, so that the stimulation source outputs a stimulation pulse signal. The process of realizing normal power supply of the power supply battery, at this time, the main controller MCU controls the first switch relay S1 to remain disconnected, and there is no need to select the delay selection module 40 for delayed power supply, and at the same time, the input and output terminals of the first diode D1 have the same potential and are in a non-working state. The main controller MCU calculates the remaining power of the current power supply battery By by detecting the voltage division between the resistors R1 and R2, and then determines whether the current battery is below the power supply range. At the same time, the main controller MCU calculates whether the voltage output by the current delay selection module meets the power supply requirements of the subsequent circuit by detecting the voltage between the resistors R3 and R4.

[0100] Further, when the remaining power of the power supply battery By is lower than the power supply demand of the device (lower than the set value of 15%), in order to maintain the operation of the subsequent circuit, the main controller MCU controls the second switch relay S2 to disconnect, and controls the first switch relay S1 to close, controls the first transistor Q1 to close to store energy for the first inductor L1, and after controlling the first transistor Q1 to disconnect, releases the stored energy to power the capacitor C3, so as to achieve the purpose of boosting the voltage at the second node Vo, calculates the voltage difference between the first node Vi and the second node Vo through the calculation formula, and then infers the voltage at the output end. When the output voltage is boosted to the power supply voltage of the subsequent device, the current switching frequency of the first transistor Q1 is maintained, and the second power supply VDD2 continues to supply power to the subsequent excitation source. Due to the increase in the potential of the current second node Vo, the diode D2 in the first power supply module is not turned on. At this time, the first power supply VDD1 continues to be powered by the diode D1, ensuring the power supply and communication of the main controller MCU. Then, the technical effect of improving power supply efficiency and delaying power supply is achieved. Compared with the situation where a conventional power supply battery module cannot supply power to a subsequent excitation source if the minimum power supply is set below 20%, the present application sets a minimum power supply threshold below 20%, which is lower than the minimum threshold of the existing power supply battery. At the same time, the present application utilizes a voltage boost process to boost the remaining power supply to a high voltage to continue to supply power to the subsequent excitation source, making full use of the remaining power to achieve the purpose of power supply delay and increasing the service life of the power supply battery.

[0101] Furthermore, in the process of starting the delay selection module to supply power to the subsequent excitation source, the actual remaining power of the power supply battery module is detected in real time by the main controller. As the remaining power continues to decrease, in order to continue to supply power to the subsequent excitation source, it is necessary to increase the voltage difference between the second node and the first node, and increase the potential of the output point of the delay selection module. The main controller increases the conduction frequency of the first transistor, increases the potential of the second node Vo, and further increases the output voltage when the input voltage continues to decrease, ensuring that the output end continues to supply power to the subsequent excitation source without being affected by the voltage drop at the input end. By continuously adjusting the conduction frequency of the first transistor, the remaining power of the power supply battery module is fully utilized to increase the power supply delay time.

[0102] Figure 3 A flow chart of a power supply delay control method provided in an embodiment of the present application. Applicable to the above-mentioned power supply delay circuit. Based on the power supply delay circuit, the problem of low power supply efficiency when the remaining power of the power supply battery is insufficient to supply power to the subsequent excitation source is solved. By boosting the voltage, the power supply voltage is increased to start the delayed power supply. Figure 3 The diagram provided, the power supply delay control method specifically includes:

[0103] S301: Obtain the battery power of the power supply battery module.

[0104] Exemplarily, the battery power may be understood as the current power of the power supply battery module.

[0105] Furthermore, the main controller detects the internal voltage of the power supply battery module in real time, and calculates the battery power of the power supply battery module under the current environment, providing reference data for the next step of determining whether to start delayed power supply.

[0106] S302: Determine a power supply requirement of a power supply battery module according to the battery power level, where the power supply requirement indicates whether the power supply battery module needs to delay power supply.

[0107] The power supply requirement mentioned here can be understood as the requirement of battery power for whether to turn on delayed power supply.

[0108] Furthermore, when the battery power is higher than the set power supply power, it is determined that the current circuit does not need to start the delayed power supply, and then the power supply demand is determined to be normal power supply. When the battery power is lower than the set minimum power supply power, it indicates that the power of the current power supply battery module is insufficient to continue to supply power to the subsequent excitation source. At this time, the delayed power supply needs to be turned on, and then the power supply demand is determined to be delayed power supply.

[0109] S303: When the power supply demand meets the delay condition, the main controller receives the delayed power supply control of the power supply battery module by the delay selection module.

[0110] The delay condition mentioned here can be understood as the delay demand when the power supply demand is delayed power supply.

[0111] Furthermore, when it is detected that the battery power of the power supply battery module is insufficient, the delay condition is met and the delayed power supply needs to be turned on. The main controller controls the internal conduction of the delay selection module and at the same time controls the internal disconnection of the second power supply module to block the second power supply module from supplying power to the subsequent excitation source. The low voltage at the input end is boosted by the delay selection module to output a high voltage. When the voltage difference between the high voltage and the low voltage exceeds the power supply voltage of the subsequent excitation source, the delayed power supply is turned on to improve the utilization rate of the remaining power, thereby achieving the technical effect of increasing the power supply time of the battery and increasing the battery life.

[0112] Figure 4 A flowchart of another power supply delay control method provided in an embodiment of the present application. Figure 4 This is introduced based on the previous embodiment. Figure 4 The diagram provided, the electrical delay control method specifically includes:

[0113] S401: Obtain the battery power of the power supply battery module.

[0114] Exemplarily, the main controller detects the internal voltage of the power supply battery module in real time, and calculates the battery power of the power supply battery module under the current environment, providing reference data for the next step of determining whether to start delayed power supply.

[0115] S402: Determine whether the battery power is greater than or equal to a preset power threshold.

[0116] S403: When the battery power is greater than or equal to the power threshold, determine that the power supply demand is a normal power supply demand.

[0117] S404: When the battery power is less than the power threshold, determine that the power supply requirement is a delayed power supply requirement.

[0118] The power threshold mentioned here can be understood as the minimum voltage value of the power supply battery to supply power to the subsequent excitation source. For example, the power threshold is set to 15% of the total power of the power supply battery. The set power threshold is lower than the 20% commonly set in the prior art, which further reflects the effect of power supply delay.

[0119] Furthermore, when the battery power of the power supply battery is higher than 15% of the total power, it indicates that the current power supply battery can continue to supply power to the subsequent excitation source, and when the battery power is lower than 15% of the total power, it indicates that the current power supply battery is seriously insufficient and cannot continue to supply power to the subsequent excitation source. The situation in which the power supply demand is met is regarded as the normal power supply demand, and the demand in which the power supply cannot be met is regarded as the delayed power supply demand.

[0120] S405: When the power supply requirement is a delayed power supply requirement, determine whether the power supply battery module meets the delay condition.

[0121] S406, controlling the first switch relay in the delay selection module to remain in a closed state, and controlling the second switch relay in the second power supply module to remain in an open state, so that the delay selection module performs delayed power supply control on the power supply battery module.

[0122] Exemplarily, when the power supply battery is low on power, the main controller closes and turns on the first switch relay, and disconnects the second switch relay at the same time, preventing the second power supply module from continuing to supply power to the subsequent excitation source. Instead, the delay selection module boosts the input low voltage to increase the output voltage. When the output voltage increases to a certain level, for example, the voltage difference between the output voltage and the input voltage of the delay selection module exceeds the power supply voltage of the subsequent excitation source, power can be supplied to the subsequent excitation source, ensuring that the subsequent excitation source continues to operate when the power supply battery is low on power, thereby improving the utilization rate of the power supply battery and achieving the purpose of power supply delay.

[0123] S407, obtaining a first output voltage of the first power supply module, and obtaining a second output voltage of the delay selection module.

[0124] S408. When the second output voltage is greater than the first output voltage, control the first diode to supply power to the first power output terminal, so that the first power supply module stops supplying power to the first power output terminal.

[0125] Furthermore, when the main controller selects the delay selection module to supply power to the subsequent excitation source, by calculating the voltage difference between the output voltage and the input voltage of the delay selection module, the voltage boost at the current output end can be clearly known. When the voltage difference just meets the power supply voltage of the subsequent excitation source, the delayed power supply is started, and the delay selection module is used to input a high voltage to the second power supply VDD2 to supply power to the subsequent excitation source. At this time, when the voltage difference or the output voltage of the delay selection module is still less than the output voltage of the first power supply module, the first power supply module is still used to output to the first power supply NDD1 to supply power to the external functional circuit. When the voltage difference or the output voltage of the delay selection module is higher than the output voltage of the first power supply module, the input end of the second diode is lower than the output end voltage, so that the second diode is blocked and the first power supply module does not work. At this time, a high voltage is output to the first diode through the delay selection module, and a high voltage is input to the first power supply through the first diode to supply power to the external functional circuit, ensuring that the external device remains in the on state. At the same time, the unidirectional conduction effect of the second diode is used to block the reverse charging of the first diode to the power supply battery module through the second diode, further ensuring the normal operation of the delay circuit.
