the list module is used for acquiring identification number information, names and optimal power of each power enhancement device to obtain a support list; the list module is also used for acquiring the name and standard power of each non-power enhancement device to obtain a non-support list; the power enhancement equipment is equipment with a PD rapid charging protocol; the optimal power is rated charging power corresponding to the identification number information given by a supplier;
the control module is used for judging whether the power supply port is accessed to the terminal equipment or not, and if not, power is not distributed; if the power enhancement device is not the power enhancement device, distributing the standard power to the terminal device based on the non-support list and the name of the terminal device;
the list module includes:
the repeated execution unit triggers a non-support unit, an identification number unit and a support unit for different types of terminal equipment to obtain a support list and a non-support list;
the non-support unit is used for accessing the terminal equipment and judging whether the terminal equipment is power enhancement equipment, if not, the name and the standard power of the terminal equipment are obtained, and if so, the identification number unit is triggered;
the identification number unit is used for acquiring identification number information of the terminal equipment, judging whether the identification number information is successfully acquired and the acquisition frequency is less than the set frequency, if the identification number information is successfully acquired and the acquisition frequency is less than the set frequency, triggering the support unit, if the identification number information is not successfully acquired and the acquisition frequency is less than the set frequency, re-acquiring the identification number information of the terminal equipment, and if the identification number information is not successfully acquired and the acquisition frequency is more than or equal to the set frequency, acquiring the name and the standard power of the terminal equipment;
the identification number unit specifically executes:
performing power source power communication on the terminal equipment, selecting any power value by the terminal equipment, sending a power request instruction to power supply equipment based on the power value, selectively accepting or rejecting the power request instruction by the power supply equipment based on the power request instruction, performing power preparation on the power supply equipment based on the power request instruction when the power preparation is selected to be accepted, sending arrival power information to the terminal equipment by the power supply equipment when the power preparation is completed, judging whether a PD message is received in a set time period before the moment of sending the arrival power information by the power supply equipment, considering that communication is busy if the PD message is received, waiting for the current PD message to be responded by the power supply equipment until the response is completed, further judging whether the PD message is received in the set time period before the moment of sending the arrival power information, considering that the communication is busy if the PD message is received, waiting for the current PD message to be responded by the power supply equipment, until the response is completed; if the PD message is not received, the power supply equipment sends a request transmission instruction to the terminal equipment, the terminal equipment sends the identification number information to the power supply equipment based on the request transmission instruction, the power supply equipment judges whether the identification number information is successfully acquired and the acquisition times are less than the set times, and if the identification number information is successfully acquired and the acquisition times are less than the set times, the identification number information, the name and the optimum power of the terminal equipment are recorded; if the acquisition is not successful and the acquisition times are less than the set times, acquiring the identification number information of the terminal equipment again, and if the acquisition is not successful and the acquisition times are more than or equal to the set times, acquiring the name and the standard power of the terminal equipment;
the supporting unit is used for recording the identification number information, the name and the optimal power of the terminal equipment.
