The invention discloses a method for achieving the pedestrian volume data collection maximization based on multi-hop Bluetooth networking, and the method employs point-to-point multi-hop Bluetooth networking for searching the data in non-agent node equipment in high-density pedestrian volume, so as to support pedestrian volume management. The multi-hop Bluetooth networking employs four function modules: a route table generation module, a routing tree construction module, a data package transmitting module and a data package receiving module. The network benefits from a Bluetooth channel of the non-agent node equipment, and the point-to-point multi-hop Bluetooth networking is constructed through the design of one route table. The method irons out a defect that conventional Ad-Hoc network non-agent node equipment cannot change the equipment identity and a defect of a static module network. The method achieves a dynamic module network, enables the number of pieces of non-agent node equipment to be maximized through region dividing and continuous updating of the non-agent node equipment, and achieves the quick transmission of a data package.
