[Abstract]:The traffic condition determines the development degree of a city, plays a key role in the people's living standard and the city's economic development. In recent years, the urban traffic problem is becoming more and more serious, the traffic jam, the transportation speed is low, in view of these problems, The State Council has issued the development strategy of public transport priority. According to the current development situation of intelligent public transport system and the application of wireless communication technology in the field of urban transportation, this paper proposes an intelligent public transportation system based on ZigBee wireless sensor network technology. ZigBee technology has the advantages of low cost, low power consumption and strong ability of self-organization network. After studying the ZigBee protocol and working principle in detail, the requirement of the whole system is analyzed. The design scheme of the whole system is put forward. The research background of this system is based on the intelligent bus system based on ZigBee. On this basis, the research of audio data transmission based on ZigBee is completed. The realization process of the system mainly includes two parts: the upper computer and the lower computer, and the lower computer collects and transmits the data. The data acquisition includes the collection of public transportation information and the acquisition of audio data. The data is transmitted through the ZigBee network created by the ZigBee module. The lower computer is connected with the PC by using the RS232 serial port line. In this system, the CC1101 wireless module is used to store the basic information of public transportation, such as vehicle ID, so as to act as the terminal node of the public transport system. Carry on the public transportation information data collection; through the head to carry on the audio data acquisition, the audio data collected need to pass the C8051F330 module to carry on the data processing. After the data collection completes, The wireless sensor network created by the hardware platform of ZigBee CC2530 is used to transmit the data. The data is transmitted to the software of the host computer to process and store the data. The software of upper computer is a visual operating interface software developed by VC 6.0 MFC technology. Finally, the system is tested and the data of public transportation information and audio are collected through the experiment. Wireless data transmission and data processing and storage have the characteristics of real time, stability and so on, which meet the expected requirements of the design, and have certain academic and practical value.
