The invention relates to a monitoring video pedestrian real-time detection, attribute identification and tracking method and system based on deep learning. The invention mainly provides an efficient pedestrian detection, attribute identification and tracking method, designs an efficient scheduling method, and performs series-parallel scheduling on modules, so that the modules can perform multi-channel video pedestrian real-time detection, attribute identification and tracking as much as possible on limited computing resources. The problems in the prior art of single monitoring function of a road scene security and protection system and that monitoring efficiency is not high are solved. The efficient multifunctional security and protection system for road scene security and protection monitoring is provided. During application, through monitoring, attribute recognition and tracking on pedestrians, the monitoring strength and intensity are enhanced, especially for important places such as airports, stations and subways, crimes can be effectively restrained, and the personal and property safety of national people is guaranteed.
