Vehicle occupancy statistics system based on WIFI (Wireless Fidelity) technology

Abstract

The invention discloses a vehicle occupancy statistics system based on a WIFI (Wireless Fidelity) technology. The vehicle occupancy statistics system comprises a GPS (Global Positioning System) subsystem, a WIFI subsystem and a data publishing subsystem installed on a vehicle, wherein the GPS subsystem is used for acquiring real-time running GPS data of the vehicle at fixed frequency, processing and screening the GPS data, setting an information acquisition point, triggering an information trigger module of the information acquisition point according to the GPS data, and storing the GPS data and data of the information acquisition point; the WIFI subsystem is used for acquiring MAC (Media Access Control) data of passengers in the vehicle, processing an acquisition trigger signal transmitted by the information trigger module, controlling a WIFI probe to acquire the MAC data according to the acquisition trigger signal, calculating current number of people data according to the MAC data,and storing the MAC data; and the data publishing subsystem is used for visually outputting a real-time location and the real-time passenger carrying situation of a bus. By means of the acquisition ability of the WiFi probe and the WiFi coverage of the bus, the MAC data of the passengers are acquired in real time, and reasonable prediction of the bus arrival distance, arrival time and real-time number of passengers are realized in conjunction with the GPS data.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted WIFI, in particular to an in-vehicle people counting system based on WIFI technology. Background technique [0002] With the development of economy and society, the development of urbanization has intensified, more and more people have moved to live in cities, and the situation of urban traffic congestion has become increasingly serious. The development of public transportation as an effective means to relieve traffic pressure has received more and more attention. The bus system is an important part of urban passenger transport, and the optimization of the operation of the bus system plays a very important role in the development of a city. The intelligent public transportation system is a public transportation intelligent dispatching system built by using the most advanced GPS / Beidou positioning technology, 3G / 4G communication technology, GIS geographic information system technology, and ...
