Large-scale terminal intelligent charging system and method thereof

Abstract

The invention discloses a large-scale terminal intelligent charging system and a method thereof. The charging system comprises a mobile phone electricity quantity detection unit, a main control unit and a charging unit. A PC periodically detects electricity quantity of all mobile phones connected with a USB port through the mobile phone electricity quantity detection unit, generates table data and transmits the table data to the main control unit. Ethernet communication between the main control unit and the PC is achieved through a main processor STM32F407, a PHY layer chip LAN8720A and an auxiliary processor STM8S005. The PC sends table data of a to-be-charged mobile phone to the main processor STM32F407 through the Ethernet. After receiving the request and processing the data, the STM32F407 issues the processed data to the corresponding auxiliary processor STM8S005 through an I2C protocol. The charging unit comprises multiple charging branches formed by a current limiting power distribution switch TPS2553 and an FSUSB30 chip. The auxiliary processor STM8S005 receives a command and then controls the TPS2553 and the FSUSB30 chip so as to allow the mobile phone to enter a charging mode to be charged. According to the invention, it can be effectively ensured that the mobile phone is sufficiently charged when communicating with the PC.

Description

technical field [0001] The invention relates to the field of mobile phone charging, in particular to a large-scale terminal intelligent charging system and a method thereof. Background technique [0002] Nowadays, with the needs of daily life and work, data transmission between mobile phones, tablets, PCs, etc. is becoming more and more frequent. The most commonly used method for transferring files between mobile phones and computers is to use a USB data cable to connect to the computer to transfer files. The disadvantage of this method is that the number of connections is very limited and the data transmission distance is relatively short. It is difficult to realize the idea of ​​long-distance or wireless data transmission in the traditional USB way. At present, the most cutting-edge method is to send data or control to the mobile phone through Ethernet (WIFI). Although it is more convenient and quicker than the traditional USB method, it still has great limitations for co...

The most commonly used method for transferring files between mobile phones and computers is to use a USB data cable to connect to the computer to transfer files. The disadvantage of this method is that the number of connections is very limited and the data transmission distance is relatively short.

It is difficult to realize the idea of ​​long-distance or wireless data transmission in the traditional USB way

At present, the most cutting-edge method is to send data or control to the mobile phone through Ethernet (WIFI). Although it is more convenient and quicker than the traditional USB method, it still has great limitations for communicating with multiple mobile phones. Each mobile phone All occupy one IP, as the number of mobile phones (terminals) increases, it will be a big challenge for PCs and even routers
