Fall protection and reverse-connection protection system and method for automobile starting power source wiring clamp

Abstract

The invention provides a fall protection and reverse-connection protection system and method for automobile starting power source wiring clamp. The fall protection and reverse-connection protection system includes a system provided with an internal battery, a switch circuit, an access device, a wiring clamp, an MCU control circuit, an external battery detection and voltage sharing circuit, an output wiring clamp current detecting circuit and a reverse-connection protection circuit. The inner battery is connected to the access device through the switch circuit. The MCU control circuit is arranged at the front end of the switch circuit. The external battery detection and voltage sharing circuit is connected between the switch circuit and the access device. The access device is connected to the output wire clamp current detection circuit. The reverse-connection protection circuit is connected with the MCU control circuit. The invention also provides a fall protection and reverse-connection protection method for the automobile starting power source wiring clamp. Voltage condition of an external power source can be detected effectively and different operation actions can be taken according to the voltage condition of the external power source, so that normal starting is ensured.

Description
