Android equipment overvoltage startup protection method and system, terminal and storage medium

Abstract

The invention relates to an Android equipment overvoltage startup protection method, which comprises the following steps that a single-chip microcomputer is added between a power supply and a power supply input end of a PCB of android equipment, after the android equipment is connected to the power supply, the power supply supplies power to the single-chip microcomputer and initializes the single-chip microcomputer, and at the moment, the power supply and the PCB are isolated by the single-chip microcomputer and cannot be connected; the single-chip microcomputer controls an ADC controller on the single-chip microcomputer to detect an accessed power supply, and judges whether the voltage of the accessed power supply accords with a set range value or not; and if yes, the power source and the PCB are connected, the button is waited for starting up, if not, the power source and the PCB are kept in a disconnected state, and the button cannot be started up in the disconnected state. According to the invention, the single-chip microcomputer is used for isolating the power supply and the PCB, when the power supply is connected, the ADC controller of the single chip microcomputer is firstly used for voltage detection, when the input voltage fluctuation is too large or a high-voltage power supply is inserted by mistake, the power supply is kept not connected with the equipment, and then the circuit board of the equipment is protected from being burnt out.

Description

technical field [0001] The present invention relates to the field of Android system technology, and more specifically, relates to an Android device overvoltage boot protection method, system, terminal and storage medium. Background technique [0002] At present, android products have been widely used in various fields of various industries, such as Internet terminals, industrial control system terminals, virtual server client terminals, etc., especially in the field of industrial control, the operating environment voltage fluctuations are very large, and android devices are not suitable for The input voltage of the power supply is different for different needs. When a high-voltage power supply is plugged into a device with a low input voltage, it is very easy to cause the device to overvoltage and burn out the board, resulting in product failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an android device o...
