【摘要】：国家正在推动“一带一路”建设,其建设的一个重要内容就是构建物流一体化网络或者交通网络,其中包括陆地、内河和海运等。对物流装备(如物流承载装备、物流运输工具)的有效监控是物流交通网络建设的重要内容。类似天津大爆炸等重大安全事件、法国巴黎恐怖袭击等国际反恐事件等给一带一路的安全造成重大隐患。危化品的在途运输安全一直是物流重点监控对象。目前我国已存在车载传感系统进行车辆状态在途监测,但广泛存在系统设备运行不稳定、更换困难以及线路铺设困难等一系列的问题。因此,研究一种用于危化品在途监测的无线传感系统节点设备,保障物流运输安全,具有重要意义。本项目针对物流的封闭环境的通信难题,构建多天线ZigBee无线传感网节点,实现危化品车内外的无线通信,并通过GPRS将信息传输到危化品物流监控平台,实现危化品的在途安全可监控管理。本论文的主要工作如下:首先,对车载系统已存在的问题进行分析,拟定了无线车载传感系统节点设计的整体方案。其次,针对危化品运输车辆内部需要监控温度、压力、液位等需求,以及封闭环境下信号传输的难题,设计多天线接收的ZigBee无线传感网节点,全面接收车内传感器节点信息,并详细设计和开发其节点的硬件模块。随之,拟定了对应的通信协议,其中软件的设计将各类传感器收集到的数据打包传输到无线车载控制设备,通过利用信号通透性增强策略以确保无线数据传输的安全性和准确性。最后,通过对与危化品物流平台的融合,实现在Web端和手机客户端的全程监控在途物流车辆的监控测试。本论文设计的多天线ZigBee节点能够较好的接收封闭环境下的无线传感网节点的感知信息,但是在多天线协同方面有有待进一步探讨。
[Abstract]:The country is promoting the "Belt and Road" construction, one of the important elements of its construction is to build an integrated logistics network or transportation network, including land. The effective monitoring of logistics equipment (such as logistics carrying equipment, logistics transportation means) is an important content of logistics transportation network construction. It is similar to Tianjin Big Bang and other important safety events. The international anti-terrorism events such as the Paris terrorist attack in France have caused serious hidden danger to Belt and Road's safety. The safety of transportation of dangerous chemicals has always been the key object of logistics monitoring. At present, there is a vehicle-mounted sensing system for vehicles in China. Status monitoring. However, there are a series of problems such as unstable operation of system equipment, difficult to replace and difficult to lay lines, etc. Therefore, a wireless sensor system node equipment is studied for monitoring dangerous chemicals on the way. It is of great significance to ensure the safety of logistics transportation. Aiming at the difficult communication problem in closed environment of logistics, this project constructs multi-antenna ZigBee wireless sensor network node to realize wireless communication inside and outside of dangerous chemicals vehicle. And through the GPRS information will be transmitted to the dangerous chemicals logistics monitoring platform to achieve the safety of dangerous chemicals can be monitored and managed. The main work of this paper is as follows: first of all, the existing problems of the vehicle system are analyzed. The whole scheme of node design of wireless vehicle sensor system is proposed. Secondly, monitoring temperature, pressure, liquid level and the problem of signal transmission in closed environment are required for dangerous chemicals transportation vehicles. The ZigBee wireless sensor network node received by multiple antennas is designed to receive the sensor node information in the vehicle, and the hardware module of the node is designed and developed in detail. Subsequently, the corresponding communication protocol is proposed. The software design transmits the data collected by all kinds of sensors to the wireless vehicle control equipment, through the use of signal permeability enhancement strategy to ensure the security and accuracy of wireless data transmission. Finally. Through the integration with dangerous chemicals logistics platform. The multi-antenna ZigBee node designed in this paper can better receive the perception of wireless sensor network nodes in closed environment. Information. However, there is a need for further discussion in the aspect of multi-antenna coordination.
