Abstract

A vehicle main control power protection warning device is mainly connected to the vehicle power supply through a power failure protection module. The power failure protection module is mainly composed of a step-down circuit and a voltage detection circuit. The step-down circuit reduces the vehicle power supply to a reference voltage value, and the voltage detection circuit detects the reference voltage value and outputs a detection signal when the reference voltage value is lower than a default value. A microprocessing unit receives the detection signal output by the power failure protection module and generates a control signal after analysis and processing. A GSM and GPRS module receives the control signal output by the microprocessing unit and sends a mobile phone text message. The microprocessing unit is also connected to a warning unit, whereby a warning action can be generated when the vehicle main control power supply is damaged, and the vehicle owner is notified by a mobile phone text message.
