A life-detecting intelligent miniature vehicle, which relates to the field of disaster rescue equipment, comprising: a single-chip microcomputer module, a motor driving module, an independent power supply module, an infrared obstacle avoidance module, a human body sensing module, a Global Positioning System (GPS) module and a Global System for Mobile communications (GSM) module; the independent power module steps down a dry battery power supply to obtain a pre-determined voltage and provides power to other modules of the life-detecting intelligent miniature vehicle; the infrared obstacle avoidance module acquires road obstacle information, and converts the road obstacle information into an electrical signal; the single-chip microcomputer module controls the motor driving module to avoid obstacles during driving; the human body sensing module senses a change in the infrared temperature of a human body and generates an electrical signal; the GSM module sends the position of a person to a mobile phone terminal of a user. The life-detecting intelligent miniature vehicle solves the problems wherein rescue is difficult at a disaster ruin site, efficiency is low, search and rescue personnel may not easily enter said side, and the position of an injured person is difficult to determine; the life-detecting intelligent miniature vehicle achieves real-time monitoring of an environment in which a vehicle body is located, and using the intelligent miniature vehicle to enter narrow and complex environments improves rescue efficiency.
