Taxi wireless immediate calling system based on ZigBee technique

Abstract

The invention relates to a taxi wireless immediate calling system based on a ZigBee technique. The invention is aimed at providing a calling system with convenience, automatic treatment on taxi calling problems, low cost and convenient maintenance. The system comprises a user handheld miniature caller, a ZigBee router installed along a street, a vehicle-mounted terminal configured in a taxi and an information management center. The user handheld miniature caller, the ZigBee router, the vehicle-mounted terminal and the information management center are in wireless connection to form a ZigBee self-organization network which can position the taxi in a coverage scope and a user sending out calls by adopting a tree cluster topological structure, the taxi and the user can carry out communication to realize appointment, and then the system provides distance information of both parties having reached appointment to assist both parties to accomplish appointment behaviors. The system can ensure that a passenger and the taxi perform real-time information communication, and is convenient for passenger traveling and for recognition between the passenger and the reserved taxi, so as to effectively improve the operating efficiency of the taxi, relieve the pressure on urban traffic and reduce resource waste.
