The invention relates to an intelligent fire escape guiding system, which is characterized by comprising a monitoring system, a single chip microcomputer, and a display system. The monitoring system comprises a smoke sensing detector, a temperature sensing detector and a light radiation detector; and the display system can output multiple kinds of different sounds, light signals and dense smoke level images. According to the intelligent fire escape guiding system, the surrounding conditions can be monitored via the smoke sensing detector, the temperature sensing detector and the light radiation detector, the display system is controlled by the single chip microcomputer according to the monitored data, and people are guided to escape from the site.
