Problems solved by technology
The disadvantage of this method is that the method proposed in this patent is based on the networking and interconnection of static Bluetooth devices. In real life, Bluetooth devices such as mobile phones move with people, and the present invention cannot effectively determine the location in an area Number of bluetooth devices in
However, the disadvantage still exists in this method is that the method proposed in this patent is based on mobile terminals in a Wi-Fi environment, and many large-scale activities are carried out in an open-air environment, and these activities cannot be reached by Wi-Fi The technology is used to detect and collect crowd flow information in these activities

Embodiment Construction
[0068] The present invention will be further described below in conjunction with the accompanying drawings.
[0069] refer to figure 1 , The specific implementation steps of the present invention are as follows.
[0070] Step 1, divide the area.
[0071] Select any densely populated area, divide the selected area into n sub-areas at intervals of 20m, and set the fixed-position smart devices in each sub-area as proxy node devices in the area.
[0072] In the selected area, set n proxy node devices.
[0073] Set all smart devices except proxy node devices in all sub-areas as non-proxy node devices.
[0074] Step 2, determine the maximum number of non-proxy nodes.
[0075] Maximum number of non-agent node devices in each sub-region
[0076]
[0077] in, Indicates the maximum number of non-agent node devices in the i-th area in each sub-area, V ZH Indicates the sending speed of the agent node device in each sub-area, t i Indicates the time required for the i-th regio...

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.
Description
technical field [0001] The invention belongs to the technical field of computers, and further relates to a method for maximizing the collection of human flow data by applying Bluetooth 4.0 networking technology in a computer wireless network. The present invention applies to specific application scenarios such as large-scale outdoor gatherings. According to various sensors carried by smart phones, basic information such as individual position information, speed, and moving direction can be collected, and by analyzing a series of individual data collected, possible The area where the accident occurred will issue an early warning and specify a reasonable flow of people scheduling method in real time. Background technique [0002] Bluetooth 4.0 is a protocol for connecting multiple Bluetooth devices. Under this protocol, a device can only work in one role (master device and slave device) at the same time. Although newer versions of the Bluetooth protocol such as Bluetooth 4.1 ...
