Abstract

The invention discloses a power source selling device and method and belongs to the technical field of accounting devices. The power source selling device comprises a power source protection module which is used for accessing an external power source and outputting a power source to a power source transformation, output detection and control module, the power source transformation, output detection and control module, a processing module, a user interface module and a secret key and data storage circuit; the power source transformation, output detection and control module is used for providing operation power sources for circuits of other modules and is connected with the processing module, controlled by the processing module and connected with an electricity utilization output panel module and monitors that whether the electricity utilization output panel module has load access or not; an I/O (Input/Output) interface of the processing module is respectively connected with a display circuit and a key circuit the user interface module comprises a display circuit and a key circuit; the secret key and data storage circuit is controlled by the processing module; reading and storage of the secret key and data storage circuit are achieved through the processing module; a maintenance communication circuit is connected with a communication port of the processing module and converts into a USB interface through a conversion circuit. The power source selling device is simple in circuit structure, low in cost and operation cost and safe and reliable due to the fact that the power source selling device is not connected with the internet.

Description

technical field [0001] The invention belongs to the technical field of accounting devices, and in particular relates to a device and method for selling power supplies. Background technique [0002] As people rely on the application of mobile electronic devices such as smartphones, PADs, laptops, electric bicycles, and electric vehicles, and the power consumption of these mobile devices increases with the improvement of their performance, this is very important for people to use these devices. Sometimes, especially in public places, there is a demand for temporary charging of these electronic devices at any time. [0003] For the provision of free power supply to public places, the general municipal and surrounding businesses will not be too active, especially in scenic spots, squares, stations and other crowded and crowded places, the power supply that can be used for emergency charging of mobile phones and other electronic devices, its resources Too scarce. [0004] The...
