【摘要】：化石能源的消耗推动了社会的发展,但是也带来环境污染、生态破坏和局部冲突等日益严重的社会问题。为了应对这些问题,各国政府在清洁可再生能源和节能减排、低碳出行等主要方面采取了诸多措施。其中,大力推广电力公交车系统是节能减排和低碳出行的重要措施之一。相应地,电力公交车系统中的充电系统配置、电池电量管理和车载智能控制等核心内容成为了研究热点。鉴于此,本文设计出一款基于Cortex-M3处理器的智能车载终端系统,实现了对电力公交车在行驶过程中的车辆位置、电池组电量等运行参数信息的测量。同时,基于Android平台开发相应的手机客户端APP应用程序,实现对车辆控制与监测。本文通过分析车载智能终端的国内外研究现状,结合电动汽车设计的关键技术路线,设计了详细的终端系统实施方案。整个系统以ARM为硬件开发平台,利用CAN总线技术实现了对车辆电池电量等车况数据采集;选用GPS为定位方式,通过STM32F103RCT6微处理器对车辆位置、速度信息解析处理,并利用串口驱动液晶模块实现数据显示;选用GPRS为无线通讯手段,将采集到的数据打包以TCP/IP协议形式发送到服务器。基于Android软件开发平台,开发了具有远程控制功能的手机应用程序,以http方式实现手机客户端与服务器二者之间的数据交互。在系统测试过程中,实现了车辆位置、速度、电池组电量等诸多信息的采集,并利用手机客户端准确监测车辆的运行状态,初步达到了预期研究目标。在后续的研究工作中,系统将融入政府充电配套工程和Baidu地图功能,实现行车轨迹的智能管理。通过进一步完善电力公交车系统的应急处理响应,使其具有良好的社会意义与应用价值。
[Abstract]:The consumption of fossil energy promotes the development of society, but it also brings serious social problems, such as environmental pollution, ecological destruction and local conflicts. In order to deal with these problems, governments are cleaning up renewable energy and saving energy and emission reduction. Many measures have been taken in many aspects, such as low carbon travel. Among them, promoting the electric bus system is one of the important measures for energy saving and low carbon travel. Accordingly, the charging system configuration in the electric bus system, The core contents of battery power management and on-board intelligent control have become the research hotspot. In view of this, this paper designs an intelligent vehicle terminal system based on Cortex-M3 processor, which realizes the vehicle position in the driving process of electric bus. At the same time, based on the Android platform, the corresponding mobile phone client APP application program is developed to realize the vehicle control and monitoring. Combined with the key technical route of electric vehicle design, a detailed implementation scheme of terminal system is designed. The whole system takes ARM as hardware development platform and realizes the data acquisition of vehicle battery and battery by using CAN bus technology. GPS is chosen as the positioning mode, the vehicle position and speed information is analyzed and processed by STM32F103RCT6 microprocessor, and the data display is realized by using the serial port driving liquid crystal module, and the GPRS is chosen as the wireless communication means. The collected data is packaged and sent to the server in the form of TCP/IP protocol. Based on the Android software development platform, the mobile phone application program with remote control function is developed. The data exchange between the client and server of mobile phone is realized by http. In the process of system testing, the collection of many information, such as vehicle position, speed, battery charge and so on, is realized. The mobile phone client is used to accurately monitor the running state of the vehicle, and the expected research goal is preliminarily achieved. In the subsequent research work, the system will be integrated into the government charging supporting project and the Baidu map function. Through improving the emergency response of electric bus system, it has good social significance and application value.
