The invention provides a method and a device for controlling a U-disk power bank in charging. An external power supply is connected into the U-disk power bank to perform charging, the U-disk power bank at least comprises a main controller, a charging and discharging module, a data transmission module and a monitoring circuit, the monitoring circuit monitors whether a load access and data transmission request exists or not, and the main controller is connected with the charging and discharging module, the data transmission module and the monitoring circuit. When the external power supply is connected into the U-disk power bank, current of the external power supply is connected. The main controller monitors whether the load access and data transmission request exists or not through the monitoring circuit. Data transmission of the data transmission module is controlled according to monitoring results, and / or the charging and discharging module is controlled to charge a load or the U-diskpower bank according to the monitoring results. According to the method and the device for controlling the U-disk power bank in charging, data transmission is conveniently controlled, power supply forthe load and the U-disk power bank is facilitated.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a control method and device for charging a U-disk power bank. Background technique [0002] At present, the power bank technology and the U disk technology are quite mature, and the circuit part is also a common circuit; however, both the power bank and the U disk are used as independent products. U-disk (spare extended memory), when integrated with U-disk charging treasure, it is inconvenient to control data transmission and supply power to the load at the same time. Contents of the invention [0003] The main purpose of the present invention is to provide a control method and device for charging a U-disk power bank, which is convenient for supplying power to loads and controlling data transmission. [0004] The invention provides a method for controlling the charging of a U-disk power bank, which is used for connecting an external power source to a U-disk power bank for ...
