【摘要】：交通状况决定一个城市的发展程度,在人们的生活水平和城市的经济发展中起着关键性的作用。近年来,城市交通问题日益严重,交通拥堵,运输速率降低,针对这些问题,国务院发布了公交优先发展战略。本文根据当前智能公交系统的发展状况和无线通信技术在城市交通领域的运用情况,提出了一种基于ZigBee无线传感网络技术的智能公交系统,并对该系统中音频数据传输进行了重点的研究。ZigBee技术具有低成本、低功耗、自组织网络能力强等优点,在详细研究了ZigBee协议及工作原理后,通过对整个系统的需求进行分析,提出了整个系统的设计方案。本系统是以基于ZigBee的智能公交系统为研究背景,并在此基础上完成对基于ZigBee的音频数据传输的研究。本系统实现过程主要包括上位机和下位机两部分,下位机进行数据的采集和传输,上位机进行数据的接收和处理。下位机中数据采集包括公交信息的采集和音频数据的采集,数据通过由ZigBee模块创建的ZigBee网络进行传输。利用RS232串口线将下位机与PC机连接起来,通过VC6.0++中 MSCOMM控件接收串口数据并传到上位机软件进行相关的处理。本系统中,利用CC1101无线模块存储公交基本信息,如车辆ID等,充当公交系统的终端节点,进行公交信息数据的采集；通过咪头进行音频数据的采集,所采集到的音频数据需经过C8051F330模块进行数据处理。数据采集完成以后,通过ZigBee CC2530硬件平台创建的无线传感网络进行数据的传输。数据传输到上位机软件中,进行相关的处理和存储,完成整个系统的设计。上位机软件是通过VC++6.0 MFC技术开发的可视化操作界面软件。本文最后对系统进行了测试实验,通过实验,实现了公交信息数据及音频数据的采集、数据的无线传输和数据的处理存储,具有实时、稳定等特点,符合设计的预期需求,具有一定的学术和实用价值。
[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.
