摘要
给出一种城市公交智能管理调度系统的总体解决方案,阐述该方案中智能公交车载系统的设计与实现方法,详细论述其硬件和软件设计的关键部分.提出一种基于新型检测模块的全新客流量采集方法,与其他方法相比可知,该方法能以较低的成本获得实时准确的客流量数据;车载系统充分利用蓝牙模块实现公交车定位、自动报站、数据传输以及数据无线更新等功能;针对车载系统接入站台系统的接入能力,运用排队理论建立数学模型并进行仿真分析,结果表明该车载系统能够成功接入站台系统.
A novel overall solution for intelligent transportation managing and scheduling system is proposed. The design and implementation of the bus-mounted system in intelligent transportation are described and then some key points in hardware and software design are discussed in detail. The new method for passenger flow collection based on the designed new module is presented. It is shown that the new method can collect accurate data at low cost and high performance compared with others. This system implements the functions of localization, automatic bus stop report, data transmission and wireless data update. Based on queue theory, a mathematical model of accessing capability is constructed and simulated. The result shows that the bus-mounted system can access station system successfully.
