Jumper cable and ignition control method

A jumper cable, comprising:

• a main control module, a startup detection module, a voltage-stabilizing power supply module, a voltage detection module, a temperature detection module, a relay control module, a startup communication module, a positive ignition clip and a negative ignition clip;
• wherein
• the startup detection module, the voltage detection module, the temperature detection module, the relay control module and the startup communication module are all connected with the main control module;
• the relay control module comprises a relay switch having a first end connected with the voltage-stabilizing power supply module and a second end connected with the startup detection module and the negative ignition clip, the voltage-stabilizing power supply module is also connected with the positive ignition clip,
• the startup communication module is also connected with the startup power supply;
• wherein the main control module is configured to send an “ON” signal after delaying a preset first delay time and the relay control module is configured to control the relay switch to couple according to the “ON” signal when detected signals of the startup detection module, the voltage detection module, the temperature detection module and the startup communication module are normal,
• the main control module is also configured to send an “OFF” signal to the relay control module and the relay control module is configured to control the relay switch to turn off according to the “OFF” signal after ignition action is completed, and
• the main control module is further configured to send an “OFF” signal to the relay control module when it reaches a preset time period after the relay switch is coupled, and the relay control module is configured to control the relay switch to turn off accordingly.
