【摘要】：车辆是现在物流的主要运输工具。在许多场合，为了确保某些货物（如鲜活农产品）在运输过程中的品质不发生变化，物流公司和货主都希望能够对货物车载微环境进行实时监控。本论文应用物联网技术，设计和实现了一个车载微环境监控系统，该系统主要由两部分组成：车载微环境监控终端和车载微环境监控中心。 （1）车载微环境监控终端是一个随车的、基于ARM和Android的嵌入式系统，通过加载本论文研制的移动App,可以将现在广泛使用的智能手机或平板电脑转变为车载微环境监控终端，从而大大降低了本论文研制的车载微环境监控系统的应用成本。车载微环境监控终端主要具有如下功能： 通过监控终端的wifi模块收集在车厢内外布置的无线传感网络感知的各种信息，并以可视化的形式在监控终端的界面显示，使得随车工作人员能及时了解货物的车载微环境； 通过监控终端的wifi模块驱动在车厢内外布置的无线控制网络的控制节点，从而开启或关闭相应的执行机构（如空调、加湿机、加氧机等等），，控制货物的车载微环境； 通过监控终端的智能计算模块，对从无线传感网络感知的信息进行智能信息处理，并根据处理的结果自动驱动无线控制网络； 通过监控终端wifi模块和3G模块实现车载无线传感/控制网路和监控中心之间的数据透传； （2）车载微环境监控中心是基于B/S模式和J2EE架构开发的系统，前端车辆的车载微环境监控终端主要通过移动互联网登录车载微环境监控中心，并保持在线状态。车载微环境监控中心主要具有如下功能： 监控中心把经过监控终端数据透传所转发的车载微环境无线传感网络感知的各种信息存入数据库，并以可视化的形式在监控中心的网页上显示，使得工作人员能够远程查看前端车辆的车载微环境信息； 监控中心通过移动互联网和XMPP协议，向前端车辆的车载微环境无线控制网络推送控制命令，控制货物的车载微环境； 监控中心通过在服务器上运行的智能计算模块，为前端车辆的监控终端提供云计算的服务； 监控中心通过监控终端上传的GPS定位信息，对车辆进行实时和动态的定位，使得工作人员能够了解车辆的实时位置和经过路径。本论文研制的车载微环境监控系统已经通过测试，并在小规模范围内进行试用。
[Abstract]:Vehicles are now the main means of transportation for logistics. In many cases, in order to ensure that the quality of some goods (such as fresh agricultural products) in the transport process does not change, logistics companies and cargo owners want to be able to carry out real-time monitoring of the on-board micro-environment of the goods. In this paper, a vehicle microenvironment monitoring system is designed and implemented by using the technology of Internet of things. The system consists of two parts: the vehicle micro environment monitoring terminal and the vehicle micro environment monitoring center. The main contents are as follows: (1) the vehicle microenvironment monitoring terminal is an embedded system based on ARM and Android. By loading the mobile App, developed in this paper, the widely used smart phone or tablet computer can be transformed into a vehicle microenvironment monitoring terminal. Therefore, the application cost of the vehicle micro-environment monitoring system developed in this paper is greatly reduced. The main functions of the vehicle microenvironment monitoring terminal are as follows: through the wifi module of the monitoring terminal, it collects all kinds of information that the wireless sensor network perceives inside and outside the car, and displays it in the interface of the monitoring terminal in the form of visualization. So that the caravan staff can understand the on-board microenvironment of the goods in time; The wifi module of the monitoring terminal drives the control nodes of the wireless control network arranged inside and outside the car, thus opening or closing the corresponding actuators (such as air conditioning, humidifier, oxygenator, etc.), and controlling the onboard micro-environment of the goods; Through the intelligent computing module of the monitoring terminal, the information perceived from the wireless sensor network is processed intelligently, and the wireless control network is automatically driven according to the result of the processing. The data transmission between the wireless sensor / control network and the monitoring center is realized by monitoring terminal wifi module and 3G module. (2) the vehicle microenvironment monitoring center is a system based on B / S mode and J2EE architecture. The vehicle microenvironment monitoring terminal of front-end vehicle logs into the vehicle micro-environment monitoring center mainly through the mobile Internet, and maintains the on-line state. The main functions of the vehicle microenvironment monitoring center are as follows: the monitoring center stores all kinds of information perceived by the wireless sensor network of the vehicle microenvironment transmitted by the monitoring terminal data into the database. It is displayed on the webpage of the monitoring center in the form of visualization, which enables the staff to remotely view the information of the on-board microenvironment of the front-end vehicle. Through the mobile Internet and XMPP protocol, the monitoring center sends the control command to the wireless control network of the vehicle in front of the vehicle, and controls the on-board micro-environment of the goods. The monitoring center provides cloud computing services for the front-end vehicle monitoring terminal through the intelligent computing module running on the server. The monitoring center can locate the vehicle real-time and dynamically by monitoring the GPS location information uploaded by the terminal, so that the staff can understand the real-time location and path of the vehicle. The vehicle-borne micro-environment monitoring system developed in this paper has passed the test and has been tested in a small scale.
