Problems solved by technology

[0002] The failure of the car power supply clamp usually has a serious impact on the starting of the car. The general situation includes insufficient starting voltage, too high starting voltage and reverse connection. If no judgment is made before starting, it will cause mechanical or electrical failure.

Embodiment 1

[0040]Analysis of the working principle of the terminal clip 4 fall-off protection circuit: after starting up, press the ignition button to enter the ignition state, the ignition clip connected to J5 is correctly connected to the external battery, and the external battery detection voltage divider circuit composed of resistors R95 and R94 6. The divided voltage OUT-CHECK is sent to the MCU control circuit 5 to judge whether the voltage of the external battery connected to the outside is within the normal ignition range (2-13.2V), when it is detected that the voltage of the external battery connected to the outside is lower or higher For the range value of normal ignition, the RELAY output control pin of the MCU control circuit 5 outputs a low level, Q13 is cut off, K1 does not work, the positive pole of BAT1 is disconnected from J5, and the ignition function is turned off. When the external battery voltage is between 2-13.2V, K1 is closed, BAT1 and J5 are connected, and the ign...

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

technical field [0001] The invention relates to a detection technology for a disconnection clip of a starting power supply of an automobile, in particular to a protection system and method for a disconnection protection and reverse connection protection of a wiring clip of a starting power supply of an automobile. Background technique [0002] The failure of the car power supply clamp usually has a serious impact on the starting of the car. The general situation includes insufficient starting voltage, too high starting voltage and reverse connection. If no judgment is made before starting, it will cause mechanical or electrical failure. . Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a system and method for protection against disconnection and reverse connection of the wiring clip of the starting power supply of an automobile. [0004] The present invention adopts following technical scheme: [0005] A car...
