Description

Technical Field

[0001] The present application relates to the field of device power supply technology, and in particular to a device power supply method, system, intelligent terminal and storage medium. Background Art

[0002] The power supply generally supplies power to the device through a voltage conversion device. When the voltage supplied by the power supply to the voltage conversion device reaches a start-up voltage, the voltage conversion device will start to supply power to the device.

[0003] In the related technology, when the vehicle battery supplies power to the device, the device also needs to be charged through the voltage conversion device. When the input voltage of the voltage conversion device is directly detected to reach the start-up voltage of the voltage conversion device, the voltage conversion device will start to supply power to the device. When it is detected that the input voltage of the voltage conversion device is lower than the shutdown voltage of the voltage conversion device, the voltage conversion device is controlled to shut down and no longer supply power to the device.

[0004] With regard to the above-mentioned related technologies, the vehicle battery transmits voltage to the voltage conversion device through wires, and the wires will cause voltage division loss. When the input voltage of the voltage conversion device is close to the shutdown voltage, the line loss will cause the input voltage of the voltage conversion device to be lower than the shutdown voltage, thereby shutting down the voltage conversion device. After the voltage conversion device is shut down, the line loss almost disappears, and the input voltage is higher than the shutdown voltage, so that the voltage conversion device starts again, causing the voltage conversion device to enter an unlimited opening and closing state, resulting in inconvenience in power supply to the equipment. There is still room for improvement. Summary of the invention

[0005] In order to improve the convenience of powering a device, the present application provides a device powering method, system, smart terminal and storage medium.

[0006] In a first aspect, the present application provides a device power supply method, which adopts the following technical solution: A device power supply method, comprising: Get the power supply trigger information of the device; According to the power supply trigger information, a preset voltage conversion device is controlled to draw power from a preset vehicle-mounted battery to supply power to the device, and verification input voltage information of the voltage conversion device is obtained; Acquire lossless input voltage information of the voltage conversion device based on the verified input voltage information; the lossless input voltage information is characterized as a voltage at the input end of the voltage conversion device that is not affected by the positive and negative line impedances; Determine whether the lossless input voltage information meets the requirements of the preset shutdown voltage information; If it does not meet the requirements, the voltage conversion device is continuously controlled to draw power from the vehicle battery to supply power to the device, and the verification input voltage information of the voltage conversion device is continuously obtained to perform cyclic judgment; If it meets the requirements, the control voltage conversion device will be shut down.

[0007] By adopting the above technical solution, when the power supply trigger information of the equipment is detected, the verification input voltage information of the voltage conversion device is detected, so as to accurately detect the lossless input voltage information of the voltage conversion device according to the verification input voltage information. When it is determined that the lossless input voltage information meets the requirements of the shutdown voltage information, it is determined that the input voltage of the voltage conversion device is lower than the shutdown voltage, so the voltage conversion device is controlled to shut down; when it does not meet the requirements, it indicates that the input voltage of the voltage conversion device is higher than the shutdown voltage, so charging continues, and the voltage conversion device will not be started and stopped without restriction due to the influence of the positive and negative line impedance, thereby improving the convenience of power supply for the equipment.

[0008] Optionally, the step of obtaining lossless input voltage information of the voltage conversion device based on the verified input voltage information includes: Determine whether the verification input voltage information meets the shutdown voltage information requirement; If not, the verification input voltage information is defined as lossless input voltage information; If it is met, the preset detection component is controlled to detect the voltage conversion device according to the preset actual detection method to determine the lossless input voltage information.

[0009] By adopting the above technical solution, the verification input voltage information and the shutdown voltage information are compared. When the verification input voltage information is greater than the shutdown voltage information, it indicates that even if there is loss, the input voltage is still greater than the shutdown voltage. Therefore, the verification input voltage information is directly defined as lossless input voltage information. When it is not greater than, accurate detection is performed, thereby improving the convenience of obtaining lossless input voltage information.

[0010] Optionally, the step of controlling a preset detection component to detect the voltage conversion device according to a preset actual detection method to determine the lossless input voltage information includes: When the verification input voltage information meets the requirements of the shutdown voltage information, the detection adjustment current information of the voltage conversion device is obtained; Controlling a preset adjustment component to adjust the current between the vehicle battery and the voltage conversion device according to the detected adjustment current information, and obtaining current adjustment completion trigger information; The detection component is controlled to detect the voltage conversion device according to the current adjustment completion trigger information to determine the lossless input voltage information.

[0011] By adopting the above technical solution, when it is determined that the verification input voltage information is not greater than the shutdown voltage information, the adjustment component is controlled to detect the adjustment current information to reduce the current between the vehicle battery and the voltage conversion device, thereby reducing the voltage division of the wire, so that the input voltage of the voltage conversion device is infinitely close to the output voltage of the vehicle battery, thereby improving the accuracy of the lossless input voltage information.

[0012] Optionally, the step of controlling a preset detection component to detect the voltage conversion device according to a preset actual detection method to determine the lossless input voltage information includes: When the input voltage information is verified to meet the shutdown voltage information requirement, rapid start / stop trigger information of the voltage conversion device is obtained; The voltage conversion device is controlled to shut down according to the fast start-stop trigger information, and the detection component is synchronously controlled to detect the voltage conversion device to determine the lossless input voltage information, and then the voltage conversion device is controlled to start up according to the fast start-stop trigger information.

[0013] By adopting the above technical solution, when it is determined that the verification input voltage information is not greater than the shutdown voltage information, the voltage conversion device is controlled to start and stop quickly, so that the current is close to zero, which greatly reduces the loss of the wires and makes the voltage division of the voltage conversion device infinitely close to the output voltage of the vehicle battery, thereby improving the accuracy of the lossless input voltage information.

[0014] Optionally, the step of obtaining verification input voltage information of the voltage conversion device includes: Obtaining preset engine working status information; Determine whether the working status information meets the requirements of the preset startup status information; If it meets the requirements, the preset startup voltage information is defined as the verification input voltage information, and the engine working status information is continuously obtained for cyclic judgment; If not, the preset detection component is controlled to detect the verification input voltage information of the voltage conversion device according to the preset interval detection method.

[0015] By adopting the above technical solution, the working status information of the engine is detected. When it is determined that the working status information meets the requirements of the starting status information, it means that the vehicle battery is powered after the engine is started, so that the voltage of the vehicle battery is always maintained at the start-up voltage information. Therefore, the start-up voltage information is directly defined as the verification input voltage information, thereby improving the convenience of obtaining the verification input voltage information.

[0016] Optionally, the step of controlling a preset detection component to detect the verification input voltage information of the voltage conversion device according to a preset interval detection method includes: Obtaining historical verification input voltage information of the voltage conversion device; Determine voltage detection interval time information based on historical verification input voltage information and preset voltage interval relationship information; Acquiring accumulated interval time information of a voltage conversion device; Determine whether the accumulated interval time information meets the requirements of the voltage detection interval time information; If it does not meet the requirement, the accumulated interval time information of the voltage conversion device is continuously obtained to perform cyclic judgment; If it is in compliance, the control detection component detects the voltage conversion device to determine the verification input voltage information, and backs up the verification input voltage information as new historical verification input voltage information.

[0017] By adopting the above technical solution, the voltage detection interval time information of the verification input voltage information is determined according to the historical verification input voltage information and the voltage interval relationship information. The smaller the previous verification input voltage information is, the smaller the detection interval is, thereby improving the accuracy of the detected verification input voltage information.

[0019] By adopting the above technical solution, the processor loads and executes a program of a device power supply method stored in the memory, thereby controlling the acquisition module to obtain a series of data related to the power supply of the device, and after detecting the verification input voltage information of the voltage conversion device, the input voltage of the voltage conversion device is accurately detected according to the verification input voltage information to obtain lossless input voltage information, so as to determine whether to turn off the voltage conversion device according to the lossless input voltage information, and the voltage conversion device will not be started and stopped unlimitedly due to the voltage division of the wire, thereby improving the convenience of charging the device.

[0020] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and executes a device power supply method as described in any one of the above items.

[0021] By adopting the above technical solution, by operating the intelligent terminal, the processor is made to load and execute a program of a device power supply method stored in the memory, thereby detecting the verification input voltage information of the voltage conversion device, and then accurately detecting the input voltage of the voltage conversion device according to the verification input voltage information to obtain lossless input voltage information, thereby judging whether to turn off the voltage conversion device according to the lossless input voltage information, and the voltage conversion device will not be started and stopped unlimitedly due to the voltage division of the wire, thereby improving the convenience of charging the device.

[0022] In a fourth aspect, the present application provides a computer storage medium capable of storing corresponding programs, which has the characteristic of facilitating the improvement of the convenience of power supply of the device, and adopts the following technical solution: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned device power supply methods.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By detecting the verification input voltage information of the voltage conversion device when the power supply trigger information of the device is detected, the lossless input voltage information of the voltage conversion device is accurately detected according to the verification input voltage information.

[0032] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] The embodiment of the present application discloses a method for a voltage conversion device to draw power from a vehicle battery to power a device, and specifically discloses a processing terminal, a device, a vehicle power supply and a voltage conversion device. The vehicle power supply serves as a starting power supply to start the voltage conversion device and enables the voltage conversion device to draw power from the vehicle battery to charge the device. The processing terminal is respectively connected to the device, the vehicle power supply and the voltage conversion device to realize data interaction and control. After the processing terminal receives the power supply trigger information of the device, the processing terminal controls the voltage conversion device to draw power from the vehicle battery to power the device, and detects the verification input voltage information of the voltage conversion device, thereby accurately detecting the input voltage of the voltage conversion device based on the verification input voltage information to obtain lossless input voltage information. When the processing terminal determines that the lossless input voltage information does not meet the requirements of the shutdown voltage information, charging continues. If it meets the requirements, it indicates that the voltage is low, so the voltage conversion device is controlled to shut down, so that the voltage conversion device will not be started and stopped without restriction due to the impedance of the positive and negative lines, thereby improving the convenience of powering the device.

[0034] Reference Figure 1 , the embodiment of the present application discloses a device power supply method, comprising the following steps: Step S100: Acquire power supply trigger information of the device.

[0035] The power supply trigger information refers to the trigger data for the device to be connected to the voltage conversion device for charging, which is selected and determined by the operator on the graphical user interface of the device and then sent by the device to the processing terminal.

[0036] Step S101: according to the power supply trigger information, a preset voltage conversion device is controlled to draw power from a preset vehicle-mounted battery to supply power to the device, and verification input voltage information of the voltage conversion device is obtained.

[0037] After the processing terminal receives the power supply trigger information, the processing terminal responds to the power supply trigger information, thereby controlling the voltage conversion device to draw power from the vehicle battery to supply power to the device, referring to Figure 7 As shown in the system diagram, the specific charging voltage and current are set in advance by the operator, and the verification input voltage information of the voltage conversion device is detected to provide data support for the subsequent determination of the precise input voltage of the voltage conversion device.

[0038] The vehicle battery refers to a battery installed on the vehicle and powered by the engine-driven generator. The vehicle battery acts as a starting battery to start the voltage conversion device, and the voltage conversion device draws power to charge the device. The voltage conversion device refers to a device whose input end is connected to the output end of the vehicle battery and whose output end is connected to the device for charging the device. The type and model of the voltage conversion device are selected by the operator according to the specific situation of the device. The voltage conversion device has a startup voltage and a shutdown voltage. The startup voltage is greater than the shutdown voltage. When the voltage at the input end of the voltage conversion device is higher than the startup voltage, the voltage conversion device starts working. When the input voltage of the voltage conversion device is less than the shutdown voltage, the voltage conversion device shuts down.

[0039] Verification input voltage information refers to the voltage at the input end of the voltage conversion device affected by the positive and negative line impedance, and is used to determine that the voltage at the input end of the voltage conversion device is not affected by the positive and negative line impedance. For specific acquisition methods, refer to Figure 5 steps.

[0040] Step S102: acquiring lossless input voltage information of the voltage conversion device based on the verified input voltage information. The lossless input voltage information is characterized as a voltage at the input end of the voltage conversion device that is not affected by the positive and negative line impedances.

[0041] Among them, after the processing terminal obtains the verification input voltage information, the lossless input voltage information of the input end of the voltage conversion device is detected and determined according to the verification input voltage information, so as to obtain the input voltage of the voltage conversion device that is not affected by the positive and negative line impedance between the vehicle battery and the voltage conversion device, and provide data support for the subsequent prevention of unlimited starting and stopping of the voltage conversion device.

[0042] Lossless input voltage information refers to the voltage at the input end of the voltage conversion device that is not affected by the positive and negative line impedance. For specific acquisition methods, refer to Figure 2 steps.

[0043] Step S103: determining whether the lossless input voltage information meets the requirement of the preset shutdown voltage information.

[0044] Among them, the shutdown voltage information refers to the voltage value at which the voltage conversion device is shut down. The specific value is determined by the operator based on the actual situation of the voltage conversion device. The requirement for the shutdown voltage information refers to a voltage value not greater than that corresponding to the shutdown voltage information, which is input and stored in the processing terminal.

[0045] By processing the terminal, it is determined whether the voltage value corresponding to the lossless input voltage information is not greater than the voltage value corresponding to the shutdown voltage information, thereby determining whether the voltage at the input end of the voltage conversion device when not affected by the positive and negative line impedances meets the working voltage requirements of the voltage conversion device, thereby providing data support for subsequent control of the voltage conversion device.

[0046] Step S1031: If not, continue to control the voltage conversion device to draw power from the vehicle battery to supply power to the device, and continue to obtain the verification input voltage information of the voltage conversion device for cyclic judgment.

[0047] Among them, if the processing terminal determines that the voltage value corresponding to the lossless input voltage information is greater than the voltage value corresponding to the shutdown voltage information, the voltage at the input end of the voltage conversion device when it is not affected by the positive and negative line impedance meets the working voltage requirement of the voltage conversion device, even if the voltage at the input end of the voltage conversion device when it is affected by the positive and negative line impedance does not meet the working voltage requirement of the voltage conversion device, the voltage conversion device is still maintained to draw power from the vehicle battery to power the equipment, and the verification input voltage information of the voltage conversion device continues to be detected, thereby continuously monitoring the changes in the input voltage of the voltage conversion device.

[0048] Step S1032: If the conditions are met, the voltage conversion device is controlled to shut down.

[0049] Among them, if the processing terminal determines that the voltage value corresponding to the lossless input voltage information is not greater than the voltage value corresponding to the shutdown voltage information, it indicates that the voltage at the input end of the voltage conversion device when it is not affected by the positive and negative line impedance does not meet the working voltage requirements of the voltage conversion device. At this time, the voltage at the input end of the voltage conversion device when it is affected by the positive and negative line impedance must not meet the working voltage requirements of the voltage conversion device, so the voltage conversion device is controlled to shut down.

[0050] Reference Figure 2 The step of obtaining lossless input voltage information of the voltage conversion device based on the verified input voltage information includes: Step S200: Determine whether the input voltage information meets the shutdown voltage information requirement.

[0051] The requirements for the shutdown voltage information in this step and the shutdown voltage information in step S103 are not described in detail here.

[0052] The processing terminal determines whether the voltage value corresponding to the verification input voltage information is not greater than the voltage value corresponding to the shutdown voltage information, thereby providing data support for the subsequent determination of the lossless voltage.

[0053] Step S201: If not, the verification input voltage information is defined as lossless input voltage information.

[0054] Among them, if the processing terminal determines that the voltage value corresponding to the verification input voltage information is greater than the voltage value corresponding to the shutdown voltage information, it means that even if there is voltage loss, the input voltage is still greater than the shutdown voltage. At this time, the voltage conversion device must be in the on state, so there is no need to perform actual detection, and the verification input voltage information can be directly defined as lossless input voltage information.

[0055] Step S202: If the conditions are met, the preset detection component is controlled to detect the voltage conversion device according to the preset actual detection method to determine the lossless input voltage information.

[0056] Among them, if the processing terminal determines that the voltage value corresponding to the verification input voltage information is not greater than the voltage value corresponding to the shutdown voltage information, the lossless voltage at the input end of the voltage conversion device may be greater than the shutdown voltage or less than the shutdown voltage. Therefore, the voltage value at the input end of the voltage conversion device that is not affected by the positive and negative line impedance needs to be actually detected, so as to control the detection component to detect the input end voltage of the voltage conversion device according to the actual detection method to determine the lossless input voltage information. The specific method is referred to Figure 3 and Figure 4 steps.

[0057] The actual detection method refers to a method for actually detecting the voltage value at the input end of the voltage conversion device without being affected by the impedance of the positive and negative lines, and is stored in the processing terminal by the operator. The detection component refers to a component used to detect the voltage at the input end of the voltage conversion device, and can be connected to the input end of the voltage conversion device using a voltage sampling circuit.

[0058] Reference Figure 3 The steps of controlling the preset detection component to detect the voltage conversion device according to the preset actual detection method to determine the lossless input voltage information include: Step S300: when the input voltage information is verified to meet the shutdown voltage information requirement, the detection adjustment current information of the voltage conversion device is obtained.

[0059] When it is determined that the lossy voltage corresponding to the verification input voltage information is not greater than the voltage corresponding to the shutdown voltage information, the detection adjustment current information is called to provide basic support for the subsequent detection of the lossless voltage of the voltage conversion device.

[0060] The detection and adjustment current information refers to the instantaneous current when detecting the lossless input voltage information, which is usually a very small constant value. The specific value is determined by the operator according to the actual situation.

[0061] Step S301: controlling a preset adjustment component to adjust the current between the vehicle battery and the voltage conversion device according to the detected adjustment current information, and obtaining current adjustment completion trigger information.

[0062] Among them, after the processing terminal obtains the detection and adjustment current information, the processing terminal controls the adjustment component to adjust the current between the vehicle battery and the voltage conversion device, making the current extremely small, thereby reducing the loss of the positive and negative pole lines, and detects the current adjustment completion trigger information to provide time data for the subsequent detection of lossless input voltage information.

[0063] The adjustment component refers to a device used to adjust the current of the power supply loop between the vehicle battery and the voltage conversion device, and can actively control the current size using the current loop. The current adjustment completion trigger information refers to the trigger data for completing the current adjustment, which is obtained by sending a feedback signal to the processing terminal after the adjustment component completes the current adjustment.

[0064] Step S302: controlling the detection component to detect the voltage conversion device according to the current adjustment completion trigger information to determine the lossless input voltage information.

[0065] Among them, after the processing terminal obtains the trigger information of the completion of current adjustment, it indicates that the current of the power supply circuit between the vehicle battery and the voltage conversion device has been reduced. At this time, there is almost no voltage division interference between the positive and negative lines. Therefore, the control detection component directly detects the input voltage of the voltage conversion device to determine the lossless input voltage information.

[0066] Reference Figure 4 The steps of controlling the preset detection component to detect the voltage conversion device according to the preset actual detection method to determine the lossless input voltage information include: Step S400: when the input voltage information is verified to meet the shutdown voltage information requirement, the rapid start-stop trigger information of the voltage conversion device is obtained.

[0067] Among them, when it is determined that the lossy voltage corresponding to the verification input voltage information is not greater than the voltage corresponding to the shutdown voltage information, the fast start and stop trigger information of the voltage conversion device is detected to provide basic support for the subsequent detection of the lossless input voltage.

[0068] The rapid start-stop trigger information refers to the trigger data for controlling the start and stop of the voltage conversion device in a very short time, and is stored in the processing terminal by the operator.

[0069] Step S401: Control the voltage conversion device to shut down according to the fast start-stop trigger information, and synchronously control the detection component to detect the voltage conversion device to determine the lossless input voltage information, and then control the voltage conversion device to start up according to the fast start-stop trigger information.

[0070] Among them, after the voltage conversion device obtains the fast start and stop trigger information, it responds to the fast start and stop trigger information to shut down the voltage conversion device. At this time, there is no current in the power supply circuit, and the loss of the positive and negative lines is minimized, so as to control the detection component to detect the input voltage of the voltage conversion device to determine the lossless input voltage information, and then control the voltage conversion device to start up according to the fast start and stop trigger information to complete the closed loop of detection.

[0071] Reference Figure 5 , the step of obtaining verification input voltage information of the voltage conversion device includes: Step S500: Obtain preset engine operating status information.

[0072] The engine refers to the engine of the vehicle, which charges the vehicle battery through the generator. When the engine is started, the output voltage of the vehicle battery reaches the rated standard voltage. The working status information refers to the working status of the engine, including the shutdown and start-up states, which are identified by the vehicle system and the status data is sent to the processing terminal.

[0073] Step S501: Determine whether the working status information meets the requirements of the preset startup status information.

[0074] The startup status information refers to data indicating that the engine is in the startup status, and the requirement for the startup status information refers to the consistency of the status corresponding to the startup status information, which is stored in the processing terminal by the operator.

[0075] The processing terminal determines whether the state corresponding to the working state information is consistent with the state corresponding to the starting state information, thereby determining whether the engine is started, providing data support for the subsequent determination of the verification input voltage information.

[0076] Step S5011: If it meets the requirements, the preset startup voltage information is defined as the verification input voltage information, and the engine working status information is continuously obtained for cyclic judgment.

[0077] Among them, if the processing terminal determines that the state corresponding to the working status information is consistent with the state corresponding to the starting status information, it means that the engine has been started and the output voltage of the vehicle battery is output according to the standard voltage. At this time, the voltage conversion device must be started, so the start-up voltage is defined as the verification input voltage information, and the working status information of the engine is continued to be detected, so as to continuously monitor the changes in the working status information of the transmitter.

[0078] The startup voltage information refers to the startup voltage of the voltage conversion device, and the specific value is determined by the operator according to the actual situation of the voltage conversion device and stored in the processing terminal.

[0079] Step S5012: If not, controlling the preset detection component to detect the verification input voltage information of the voltage conversion device according to the preset interval detection method.

[0080] Among them, if the processing terminal determines that the state corresponding to the working state information is inconsistent with the state corresponding to the starting state information, it means that the engine has not started, and the voltage conversion device is powered only by the voltage of the vehicle battery itself. Therefore, according to the interval detection method, the detection component is controlled to detect the input voltage of the voltage conversion device, so as to obtain the verification input voltage information. The specific method is referred to Figure 6 steps.

[0081] The interval detection method refers to a method of detecting the voltage at the input end of the voltage conversion device at a certain interval, which is stored in the processing terminal by the operator. The detection component refers to a component used to detect the voltage at the input end of the voltage conversion device, which can be connected to the input end of the voltage conversion device using a voltage sampling circuit.

[0082] Reference Figure 6 The step of controlling the preset detection component to detect the verification input voltage information of the voltage conversion device according to the preset interval detection method includes: Step S600: Acquire historical verification input voltage information of the voltage conversion device.

[0083] The historical verification input voltage information refers to the verification input voltage obtained by the voltage conversion device during the last detection, which is obtained by calling the processing terminal.

[0084] Step S601: verify input voltage information and preset voltage interval relationship information according to history to determine voltage detection interval time information.

[0085] Among them, the voltage interval relationship information refers to a database that stores the corresponding relationship between voltage value and detection interval time. The voltage value is proportional to the detection interval time, that is, the smaller the voltage value, the smaller the detection interval time. The operator will match the two one by one according to the actual situation and store them in the processing terminal.

[0086] The voltage detection interval time information refers to the time interval between the detection of the current verification input voltage and the last detection, and is obtained by the processing terminal matching and outputting the voltage input voltage interval relationship information corresponding to the historical verification input voltage information in the database.

[0087] Step S602: Acquire the accumulated interval time information of the voltage conversion device.

[0088] The accumulated interval time information refers to the time from the last voltage detection of the voltage conversion device, which is detected by the timer and sent to the processing terminal.

[0089] Step S603: determining whether the accumulated interval time information meets the requirements of the voltage detection interval time information.

[0090] The requirement of the voltage detection interval time information is equal to the time corresponding to the voltage detection interval time information. The processing terminal determines whether the time corresponding to the accumulated interval time information is equal to the time corresponding to the voltage detection interval time information, thereby determining whether the time for detecting the verification input voltage has arrived.

[0091] Step S6031: If not, continue to obtain the accumulated interval time information of the voltage conversion device to perform a cyclic determination.

[0092] Among them, if the processing terminal determines that the time corresponding to the cumulative interval time information is not equal to the time corresponding to the voltage detection interval time information, it means that the time for detecting the verification input voltage has not yet arrived, so the cumulative interval time information of the voltage conversion device continues to be detected, thereby continuously monitoring the changes in time.

[0093] Step S6032: If it is in compliance, the detection component is controlled to detect the voltage conversion device to determine the verification input voltage information, and the verification input voltage information is backed up as new historical verification input voltage information.
