[0010] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Refer to Figure 1 - Figure 2, embodiments of the present aspect provide a custom interaction method for a mobile power supply and a mobile power supply. The custom interaction method for the mobile power supply is applied to the mobile power supply. The custom interaction method for the mobile power supply includes the following steps: S101. Set a mobile power supply as the master device. The master device includes a display screen and a button module. The button module includes a main power switch button and an AC inverter switch button; S102. When the AC output is in the off state and the main power switch button and the AC inverter switch button are long-pressed simultaneously, the display screen flashes the AC voltage icon and the AC frequency icon simultaneously to prompt the master device to enter the AC output voltage and frequency setting mode; S103. After entering the AC output voltage and frequency setting mode, click the main power switch button, and the AC output voltage and frequency increase by a set value once. Long-press the main power switch button, and the AC output voltage and frequency continuously increase by the set value. The increased set value is displayed through the AC voltage icon and the AC frequency icon; S104. After entering the AC output voltage and frequency setting mode, click the AC inverter switch button, and the AC output voltage and frequency decrease by a set value once. Long-press the AC inverter switch button, and the AC output voltage and frequency continuously decrease by the set value. The decreased set value is displayed through the AC voltage icon and the AC frequency icon.

[0011] It should be noted that in this embodiment, by providing the function for the user to directly control the AC output voltage and frequency of the mobile power supply, personalized management and use are realized. This interaction method allows the user to adjust the output voltage and frequency according to the requirements of different electrical devices to ensure that the devices can operate under the best conditions. For example, some precision devices have specific requirements for voltage and frequency. Through this solution, the user can flexibly adjust the output of the mobile power supply to meet these specific needs. This not only improves the practicality of the mobile power supply but also enables the user to make full use of its functions.

[0012] In step S101, by designating a mobile power supply as the master device and providing a display screen and a button module, the foundation for user interaction with the mobile power supply is laid. The display screen can be used to provide an intuitive interface to display the current setting status, while the button module provides a means of control for the user. In step S102, by simultaneously long-pressing the main power switch button and the AC inverter switch button, the AC output voltage and frequency setting mode is entered and a flashing AC voltage and frequency icon is displayed. This design can prevent misoperation and ensure that the user can enter the setting mode only when clearly intending to adjust the output parameters. In addition, the flashing icon serves as a visual feedback, indicating to the user that the setting state has been entered, providing a better user experience. In step S103, two interaction methods for increasing the AC output voltage and frequency, single-time and continuous, are provided, which are achieved by clicking and long-pressing the main power switch button respectively. This design increases the flexibility of operation. The user can precisely adjust the output value by single-clicking or quickly adjust it by long-pressing. The icons on the display screen synchronously display the adjustment results, allowing the user to know the setting status at any time. In step S104, two interaction methods for decreasing the AC output voltage and frequency, single-time and continuous, are provided, which are achieved by clicking and long-pressing the AC inverter switch button respectively. The user can precisely or quickly decrease the output parameters. This design enables the user to flexibly adjust the output value in two directions, and also provides real-time feedback through icon display to ensure the accuracy of operation. Generally speaking, through the combined design of buttons and the display screen in this embodiment, an intuitive and flexible setting method for the AC output voltage and frequency of the mobile power supply is provided for the user. Through the custom interaction method of the mobile power supply, the user can perform personalized management of the mobile power supply according to actual needs, enabling it to fully exert its functions. Moreover, considering the user experience and operation accuracy, it not only prevents misoperation but also provides real-time visual feedback, thus enhancing the interaction experience between the user and the device.

[0013] In some preferred embodiments, the master device further includes an MCU module, a power supply system, and an inverter module circuit. The MCU module is disposed inside the housing of the mobile power supply; the power supply system is electrically connected to the battery module and the MCU module inside the housing of the mobile power supply respectively, and is used to obtain a DC signal from the battery module, output it to supply power to a DC load connected to the power supply system, and transmit the output status signal of the DC signal to the MCU module; the display screen is disposed outside the housing of the mobile power supply and is electrically connected to the MCU module, and is used to display the status of the DC signal output according to the DC output status display control signal transmitted by the MCU module, and the DC output status display control signal is generated by the MCU module according to the output status signal of the DC signal; the inverter module circuit is electrically connected to the battery module, and is used to output an AC signal to an AC load connected to the inverter module circuit, and perform overload or overcurrent detection, and stop outputting the AC signal to the AC load when an overload or overcurrent occurs. In this embodiment, the inverter module circuit has an overload or overcurrent detection function. When the AC load connected to the mobile power supply has an overload or overcurrent, the inverter module can detect the abnormality in time and stop supplying power to the AC load, thereby improving the stability of the custom interaction method of the mobile power supply during use, preventing circuit damage or equipment failure caused by overcurrent or overload, and improving the safety and reliability of the equipment. During the process of outputting electrical energy to the AC load, the inverter module is responsible for converting the DC signal provided by the battery module (such as a battery pack) into an AC signal. If an overcurrent or overload situation is detected, the inverter module will actively cut off the power supply to avoid faults caused by excessive current. In addition, the MCU module is the core control unit of the entire master device. It is responsible for receiving and processing the electrical signals from the power supply system and converting these signals into status information that can be used for display. The power supply system is electrically connected to the battery module and the DC load, and is responsible for managing the DC output of the battery. It also monitors the output status of the DC signal and transmits the status signal to the MCU module for processing. The display screen is electrically connected to the MCU module and is used to display the DC output status processed by the MCU. Users can intuitively understand important information such as the charging and discharging status and the remaining power of the mobile power supply through the display screen, so that users can more conveniently master the operation of the device, thereby improving the use experience of the mobile power supply. Further, the inverter module circuit is also used to be connected to the mains power, and work in the charging state to charge the battery module after detecting the mains power access. It can be understood that the main function of the inverter module is to invert DC into AC to supply the AC load. However, when the inverter module has the mains power access detection and charging function, the mobile power supply is not only a device that provides power support for external devices, but also can charge its own battery module reversely through the mains power, thereby increasing the flexibility of the master device.When the mains power supply is detected, the inverter module can be switched to the charging state to use the mains power to supplement the power of the internal battery module.

[0014] In some preferred embodiments, the AC inverter switch button is arranged outside the housing of the mobile power supply and is electrically connected to the MCU module, and the MCU module is electrically connected to the inverter module circuit; when the inverter module circuit is connected to the mains power supply and works in the charging state, when the MCU module receives the AC discharge signal triggered by the pressing of the AC inverter switch button, the MCU module sends a UPS state working control signal to the inverter module circuit to control the inverter module circuit to work in the UPS state and output an AC signal to supply power to the AC load. It should be noted that by setting the AC inverter switch button outside the mobile power supply, the user can directly control the working state of the inverter module through simple button operations. Compared with automatic control or relying on external signals, the button module provides a more intuitive and user-friendly interaction method, which helps to improve the convenience of using the mobile power supply. In the UPS (Uninterruptible Power Supply) state, the mobile power supply can quickly switch to battery power supply when the mains power fails, ensuring uninterrupted power supply to the AC load and ensuring continuous power supply to devices with high requirements for power supply stability. By controlling the inverter module to enter the UPS state through the MCU module, the safety and stability of the mobile power supply can be effectively improved. When the mains power is disconnected or a fault occurs, the UPS state can ensure the stability of the power supply and prevent damage to the device caused by power interruption. Further, the MCU module and the inverter module circuit are electrically connected through a CAN communication line, or through an RS485 communication line, or through a UART communication line. It can be understood that the MCU and the inverter module are electrically connected through the CAN, RS485 or UART communication line, so that the appropriate communication method can be selected according to different application scenarios. CAN provides high reliability and anti-interference ability, which is suitable for complex electromagnetic environments; RS485 supports long-distance transmission and is suitable for industrial scenarios; UART meets the short-distance communication requirements with its low cost and simplicity.

[0015] In some preferred embodiments, the power supply system is connected to the DC load through a DC-DC module; the DC-DC module is electrically connected to the MCU module and is used to perform DC-DC processing on the DC signal provided by the power supply system and then output it to supply power to the DC load. It should be noted that the DC-DC module (DC-DC conversion module) can convert a DC voltage into another different DC voltage and usually includes functions of boosting or bucking. The battery of a mobile power supply usually provides a fixed DC voltage, but different DC loads may require different voltage ranges. Through the voltage conversion of the DC-DC module, it can ensure that the load obtains a stable and suitable voltage, thereby improving the working efficiency of the system. For example, some devices may require 5V power supply, while others may require 12V or higher voltage. The DC-DC module ensures stable power supply by converting the battery voltage into a voltage suitable for the load and will not affect the normal operation of the load due to voltage mismatch. In addition, the DC-DC module includes a voltage stabilizing circuit, which can ensure that the voltage output to the DC load remains within a certain range and avoid the influence of voltage fluctuations on the load device.

[0016] In some preferred embodiments, the power supply system is electrically connected to the LED lighting module and is connected to the USB load through a USB module; the LED lighting module and the USB module are respectively electrically connected to the MCU module. In addition, the mobile power supply further includes a WIFI module, a Bluetooth module, a voice module, and an MPPT module; the WIFI module, the Bluetooth module, the voice module, and the MPPT module are respectively electrically connected to the MCU module, and the MPPT module is used to receive photovoltaic input and perform power conversion and store it in the battery module. It should be noted that in this embodiment, by electrically connecting the power supply system to the LED lighting module, the mobile power supply not only has basic power storage and output functions but also can provide a lighting function. By connecting a USB load through the USB module, it can charge devices such as mobile phones, tablets, and cameras. Through the WIFI module, the mobile power supply can be connected to external network devices to realize remote control, monitoring, and communication functions. Through the Bluetooth module, the mobile power supply can be paired with devices such as mobile phones and tablets through Bluetooth, allowing users to directly control and manage the mobile power supply through a local Bluetooth connection. Through the voice module, the mobile power supply can be operated through voice commands, reducing the trouble of manual operation by users. By receiving photovoltaic input through the MPPT (Maximum Power Point Tracking) module and performing power conversion, the electrical energy of solar energy can be converted into direct current and stored in the battery module. The MPPT module can dynamically adjust working parameters according to lighting conditions to ensure that the solar panel can achieve maximum power output under different environments, enabling the mobile power supply to make full use of solar energy for charging in outdoor environments.

[0017] In some further embodiments, the inverter module circuit includes a mains detection circuit, a test port isolation and current limiting circuit, a bidirectional inverter, and an overload or overcurrent detection circuit; the mains detection circuit is connected to the bidirectional inverter and the test port isolation and current limiting circuit, and transmits the AC power signal to the bidirectional inverter after detecting the AC power signal of the mains; the test port isolation and current limiting circuit unidirectionally isolates and limits the current of the power test port from the mains detection circuit; the bidirectional inverter is connected to a battery module (such as a battery pack) and an MCU module, and provides an AC power signal output port to output an AC power signal to supply power to an AC load; the overload or overcurrent detection circuit is connected to the AC power signal output port and the bidirectional inverter, and transmits an overload or overcurrent detection signal to the bidirectional inverter, so that the bidirectional inverter stops outputting the AC power signal when overloaded or overcurrent. It should be noted that in this embodiment, the mains detection circuit ensures that when the mains is available, the mobile power supply can effectively use the mains for charging or power supply. The test port isolation and current limiting circuit can unidirectionally isolate the power test port from the mains detection circuit and limit the current inflow, preventing circuit damage or overheating caused by excessive current. The bidirectional inverter has the ability to work bidirectionally. It can convert DC power into AC power for load use; it can also work in reverse to use the mains for charging. The overload or overcurrent detection circuit monitors the AC power signal output port, and when detecting an overload or overcurrent situation, sends a detection signal to the bidirectional inverter, requiring it to stop output, avoiding equipment damage and improving the stability of the custom interaction method of the mobile power supply. In addition, the specific structure of the mains detection circuit is a conventional technology in the art and will not be elaborated in this embodiment. Further, the test port isolation and current limiting circuit includes a diode D1 and a current limiting resistor R1; the anode of the diode D1 is connected to the mains detection circuit, and the cathode of the diode D1 is connected to the power test port through the current limiting resistor R1. It should be noted that the diode D1 plays a role of unidirectional conduction in the circuit. It ensures that the current between the mains detection circuit and the power test port can only flow in a single direction. This unidirectional isolation protection mechanism can effectively prevent the signal of the power test port (such as an insertion signal) from entering the mains detection circuit in the reverse direction, avoiding possible electrical interference or reverse current from damaging the mains detection circuit. The current limiting resistor R1 limits the magnitude of the current flowing through the power test port in the circuit. It ensures that the power test port will not be damaged or affect the function of the mains detection circuit due to excessive current. Through the combined design of the diode D1 and the current limiting resistor R1, the electrical isolation between the power test port and the mains detection circuit is ensured, and at the same time, the influence brought by current fluctuations is reduced through the current limiting resistor, thereby improving the signal stability and test accuracy of the power test port. Diodes and current limiting resistors are very common and simple electronic components, with low cost and easy implementation. This combined design does not significantly increase the complexity or cost of the system while ensuring the safety of the circuit.By simply connecting the diode D1 and the resistor R1 in series, various functions such as isolation, current limiting, and protection can be effectively achieved. Further, the overload or overcurrent detection circuit includes a resistor R2, a resistor R3, a resistor R4, an operational amplifier U1, a resistor R5, a resistor R6, a resistor R7, a diode D2, and a capacitor C1; the resistor R2 is connected to the AC signal output port of the bidirectional inverter and is connected to the non-inverting input terminal of the operational amplifier U1 through the resistor R3. The non-inverting input terminal of the operational amplifier U1 is also connected to the reference voltage VREF+ through the resistor R4; the inverting input terminal of the operational amplifier U1 is grounded through the resistor R5 and is connected to one end of the parallel unit of the resistor R6 and the capacitor C1. The other end of the parallel unit of the resistor R6 and the capacitor C1 is connected to the output terminal of the operational amplifier U1 and the first end of the resistor R7. The second end of the resistor R7 is connected to the bidirectional inverter through the diode D2. It should be noted that the resistor R2 is connected to the AC signal output port of the bidirectional inverter, and a part of the AC signal is introduced into the detection circuit through voltage division for overload or overcurrent detection. The resistor R3 is connected to the non-inverting input terminal of the operational amplifier U1. R3 and R2 together form a voltage divider for adjusting the input signal voltage to ensure that the input voltage is within the operating range of the operational amplifier. The resistor R4 connects the reference voltage VREF+ to the non-inverting input terminal of the operational amplifier U1. This reference voltage is used to set a reference level for comparison with the input signal. The reference voltage VREF+ is usually set to a stable voltage according to system requirements to determine the maximum allowable current or voltage value. When the input signal (the voltage obtained through R2 and R3) exceeds the reference voltage, it indicates an overload or overcurrent, and the operational amplifier will output a corresponding signal. The operational amplifier U1 is responsible for comparing the input signal and the reference voltage and outputting an amplified differential signal. The non-inverting input terminal of the operational amplifier receives the AC signal processed by the resistor R3, while the inverting input terminal is grounded through the resistor R5 and is connected to the parallel unit of R6 and C1, forming a feedback network. The operational amplifier U1 compares the voltages at the non-inverting and inverting input terminals. When the input AC signal voltage exceeds the reference voltage, the operational amplifier U1 outputs a high-level signal, indicating that the current or voltage exceeds the set threshold, thereby triggering a protection action. The resistor R5 grounds the inverting input terminal of the operational amplifier to ensure that the voltage at the inverting terminal is zero level, so that the output of the operational amplifier can accurately reflect the change of the input signal. The parallel unit of the resistor R6 and the capacitor C1 forms a feedback network for stabilizing the operation of the operational amplifier, preventing high-frequency noise interference, and providing circuit time response adjustment in some cases. The resistor R6 provides linear feedback to control the gain of the operational amplifier, thereby limiting the amplification factor of the circuit and preventing signal over-amplification. The capacitor C1 provides frequency compensation to eliminate high-frequency noise and ensure the stable operation of the operational amplifier. The capacitor C1 can also avoid false detection by adjusting the response speed of the circuit. The resistor R7 is connected to the output terminal of the operational amplifier to limit the current flowing from the output terminal of the operational amplifier to the bidirectional inverter.The resistor R7 plays a protective role when the output current of the operational amplifier is too large, preventing unnecessary impacts on the subsequent circuit. The diode D2 is used to protect the input end of the bidirectional inverter module, preventing the signal output by the operational amplifier from flowing back to the inverter in the reverse direction and generating reverse current. The unidirectional conduction characteristic of the diode D2 ensures that the signal can only flow from the operational amplifier to the inverter when overload or overcurrent occurs, thereby triggering the inverter to stop working.

[0018] In some preferred embodiments, when the AC output voltage and frequency are set, press and hold the main power switch button and the AC inverter switch button simultaneously. The display screen will flash the AC voltage icon and the AC frequency icon simultaneously to prompt the main device to exit the AC output voltage and frequency setting mode. Additionally, the button module further includes a DC switch button. In the DC output off state, click the DC switch button, and the display screen will light up the DC function icon, the TYPE C function icon, and the USB A function icon simultaneously to prompt the main device to enter the DC output mode. After the main device enters the DC output mode, click the DC switch button, and the display screen will turn off the DC function icon, the TYPE C function icon, and the USB A function icon simultaneously to prompt the main device to exit the DC output mode. Additionally, when pressing and holding the main power switch button, the AC inverter switch button, and the DC switch button simultaneously, the display screen will flash the remaining time area icon 234 (the remaining time area icon 234 includes: the running time icon, the time display icon, and the time unit icon) to prompt the main device to enter the shutdown timer setting mode. After the main device enters the shutdown timer setting mode, click the DC switch button to set the shutdown time. Further, after the shutdown time setting is completed, press and hold any two of the main power switch button, the AC inverter switch button, and the DC switch button simultaneously, and the main device will exit the shutdown timer setting mode. The display screen will display the countdown hours and minutes in sequence through the running time icon, the time display icon, and the time unit icon and then return to normal display. Further, according to the countdown setting, after the countdown ends, if there is no charging state, the main device will enter the shutdown state. Additionally, when pressing and holding the AC inverter switch button and the DC switch button simultaneously, the input power icon and the output power icon on the display screen will flash to prompt the main device to enter the input maximum power setting and output maximum power setting mode. After the input maximum power and output maximum power are set, the input power value icon and the output power value icon on the display screen will display the set values of the input maximum power and the output maximum power. Further, when the main device is running according to the set values of the input maximum power and the output maximum power, the operating temperature of the main device is detected. When the detected operating temperature of the main device is abnormal, the factory default values of the input maximum power and the output maximum power are restored.In addition, the button module further includes an LED lighting switch button and a Bluetooth / WiFi switch button; when the LED lighting switch button is long-pressed, the main device turns on / off the LED lighting function, and the display screen lights up / turns off the lighting icon; after the LED lighting function is turned on, clicking the LED lighting switch button can adjust the LED brightness and mode; clicking the Bluetooth / WiFi switch button, the main device turns on / off the Bluetooth / WiFi function, and the display screen lights up / turns off the Bluetooth function icon and the WiFi function icon; when the Bluetooth / WiFi switch button is long-pressed, the Bluetooth / WiFi module is reset. It should be noted that long-pressing the main power switch button and the AC inverter switch button simultaneously to exit the setting mode of the AC output voltage and frequency can prevent the user from accidentally exiting the setting mode and ensure that the user will only exit when they clearly intend to end the setting. This combined button operation serves as a safety measure to avoid misoperation and improve the reliability of the setting. At the same time, the display screen flashes the AC voltage and frequency icons to provide visual feedback, indicating to the user that they have successfully exited the setting mode. In addition, in the DC output off state, clicking the DC switch button enters the DC output mode, and the display screen simultaneously lights up the DC function icon, the TYPE C function icon, and the USB A function icon. This design intuitively shows the user the currently entered DC output mode, clearly indicating that the DC output has been turned on. Through a simple click operation, the user can conveniently turn on or off the DC output to meet the power requirements of DC devices. In addition, through the icon indication, the user can quickly identify the current output state and avoid misoperation. In addition, long-pressing the main power switch button, the AC inverter switch button, and the DC switch button simultaneously enters the timed shutdown setting mode, providing the user with the option to automatically turn off the device after a specific time. This is of great significance in saving power and ensuring safety. Clicking the DC switch button for timed setting allows the user to set the countdown time according to their needs. When exiting the timed setting mode, the button combination requires any two buttons to be long-pressed simultaneously, providing double confirmation to prevent misoperation. At the same time, the display screen further prompts the user about the current setting through the countdown display, enabling the user to have a clear understanding of the device status. In addition, long-pressing the AC inverter switch button and the DC switch button simultaneously enters the input maximum power and output maximum power setting mode, thus providing custom settings for the power parameters. This function allows the user to optimize the input and output power of the power supply according to different device requirements and usage scenarios. By setting the input and output maximum powers, the user can better manage the performance of the mobile power supply and avoid overload or unnecessary energy consumption.It should be noted that although the user's independent setting of the maximum input and output power can better manage the performance of the mobile power supply, there may still be improper power settings. Therefore, when the main device operates according to the set values of the maximum input power and the maximum output power, the operating temperature of the main device is detected. When an abnormal device operating temperature is detected, the factory default values are automatically restored to ensure the safe operation of the device and prevent overload or overheating caused by improper power settings, which may lead to safety problems. In addition, the LED lighting switch button facilitates the user to turn on or off the lighting function when needed, increasing the practicality of the mobile power supply. The Bluetooth / WIFI switch button can control the wireless communication function of the mobile power supply. By clicking to turn on / off the Bluetooth / WIFI function, the user can easily control the wireless connection, improving the flexibility of device connection and control. The icon on the display screen indicates the current Bluetooth / WIFI status, providing clear status feedback. Long pressing the Bluetooth / WIFI switch button resets the module, facilitating the solution of possible connection failures or device pairing problems.

[0019] In some preferred embodiments, when the display screen displays icons, a circular battery level icon is displayed in the middle of the screen. The circular battery level icon is surrounded by a plurality of arc-shaped battery levels at intervals. Inside the circular battery level icon, a battery percentage icon, a low-temperature warning icon, an abnormal fault icon, a fan icon, and a high-temperature warning icon are displayed. The battery percentage icon is located at the center position inside the circular battery level icon. The low-temperature warning icon, the abnormal fault icon, and the high-temperature warning icon are sequentially distributed at intervals from left to right below the battery percentage icon. The fan icon is located above the battery percentage icon. At the upper left corner outside the circular battery level icon, battery pack power input and output icons are distributed. Below the battery pack power input and output icons, an operating time icon, a time display icon, a time unit icon, and an AC voltage icon are sequentially distributed at intervals from top to bottom.

It should be noted that conventional mobile power supplies usually only provide simple power indication and lack detailed display of power status, temperature warning, device operating status, etc. Users cannot timely understand the working status and potential problems of the mobile power supply. In this embodiment, by setting a circular battery level icon in the middle of the display screen and using the design surrounded by a plurality of arc-shaped battery levels at intervals, an intuitive power display method is provided. The inside of the circular battery level icon contains information such as battery percentage, low-temperature warning, abnormal fault, fan, and high-temperature warning, enabling users to clearly understand the power status and working status of the battery and take timely measures. Displaying these icons centrally allows users to obtain all key information in one area, improving the usability and safety of the device. Additionally, by setting a series of function icons outside the circular battery level icon, such as input power, lighting, wireless charging, Bluetooth function, WiFi function, parallel / expansion, mains access, MPPT, DC function, TYPE C function, USB A function, inverter output frequency, output power, and UPS function, rich device status and function information can be provided within a limited screen space, facilitating users to quickly view and operate. This way of centrally displaying information greatly enhances the user's sense of control over the device, ensuring that they can make full use of various functions of the mobile power supply.In addition, by setting the input power, output power, and numerical icons outside the circular battery level icon, users can view the power input and output of the power bank in real time. Combining with the battery pack power input / output icons, a complete working state of the battery pack is provided, allowing users to adjust their usage strategies according to actual needs, avoid over-discharging or overloading, and extend the device life.

[0020] In some preferred embodiments, when other mobile power supplies are paralleled with the master device as slave devices, the slave devices are connected and communicated with the master device through an automatic ID address allocation method. The slave devices do not have a display screen. After the slave devices are connected and communicated with the master device, the parameters of the slave devices are set by operating the key module of the master device, and the parameters of the slave devices are displayed to the user through the display screen of the master device; the automatic ID address allocation method includes: in the master device and the slave devices, the master device and the slave devices are the superior devices when sending heartbeat signals and the inferior devices when receiving heartbeat signals; after the superior device sends the heartbeat signal, the inferior device receives the heartbeat signal to complete device access, and the inferior device that has completed access enables the heartbeat signal for other inferior devices. The heartbeat signal sends a hexadecimal ID number to the inferior device with 10us high level and 90us low level as BIT1, and 90us high level and 10us low level as BIT0. The inferior device sets its own address according to the ID number. It should be noted that when multiple mobile power supplies are paralleled for use, the slave devices usually lack an independent display screen and operation interface, making it complicated and inconvenient to independently set the parameters of the slave devices and monitor the status. In this embodiment, by having the master device be responsible for setting the parameters and displaying the status of the slave devices, the entire paralleling operation process can be simplified. The user can uniformly manage all slave devices only through the key module and the display screen of the master device, thereby improving the operation convenience, avoiding the trouble of directly operating on the slave devices without a display screen, and making the entire system more user-friendly and intuitive. When multiple devices are paralleled, a unique communication address needs to be assigned to each device to ensure correct communication between the devices. In this embodiment, through the automatic ID address allocation method, automatic address allocation can be achieved between the master device and the slave devices. The master device sends a heartbeat signal, and the device that receives the heartbeat signal automatically becomes an inferior device, and a unique ID address is allocated through the heartbeat signal. This automatic allocation method ensures that each device can obtain a unique communication address, avoids the cumbersome process of manual setting, reduces the possibility of human errors, and improves the stability and reliability of the system. Additionally, in this embodiment, by designing the high and low levels of the heartbeat signal to represent different BIT values, with 10us high level and 90us low level as BIT1, and 90us high level and 10us low level as BIT0, a hexadecimal ID number is sent to the inferior device. This refined time control ensures the accuracy of signal transmission, enabling the devices to quickly and accurately complete the ID address allocation. At the same time, this communication method occupies an extremely short signal transmission time (a total of 100us), ensuring efficient communication.
