Design of Intelligent Public Transportation System based on ZigBee Technology

摘要

In this article, an intelligent public transportation system based on ZigBee 3.0 technology is proposed after researching conditions of recent public transportation systems that mostly adopt GPS or Beidou satellite positioning technology, 3G/4G communication technology and GIS technology. This system includes the principle and design of system architecture, design of intelligent public transportation system network, the solution of moving-bus positioning, the auto-announce function and design of intelligent public transportation stop board. Contrasted with recent bus systems, this system has the virtue of low construction cost, low running cost, low implementation difficulty and high intelligent level. ZigBee 3.0 protocol is compatible with Wi-Fi, too. Without additional ZigBee chip in smart phones, the intelligent public transportation system based on ZigBee 3.0 can interconnect with smart phones directly. It will break the barrier between citizens and intelligent public transportation systems, and the real intelligence can be realized.
