【摘要】：我国经济的飞快发展使广大居民生活品质逐渐提高,健康意识逐渐增强,消费者对于生鲜产品(如清新蔬菜、肉蛋类食物等)的需求量急速上升。但是,由于我国冷链物流技术普及和应用程度还不够高,所以这些食品在物流输运过程中损耗过大,食品的安全也得不到应有的保障。因此,为满足当下社会的需求,冷链技术快速运用和推广已经迫在眉睫。研究表明,冷链物流的关键在于一套完整的温度实时监控系统。过去大多数物流企业都习惯采取传统的粗放式管理模式,没有做到温度的有效实时监控和管理,因而为企业带来了不必要的经济损失,也成为了影响广大居民健康饮食的不安定因素。为解决以上问题,本文设计了一种集ZigBee网络,GPRS数据传输和GPS定位于一体的冷链物流输运远程监控系统。该系统由三个组成部分构成,包括车载终端、监控中心和通讯链路。车载终端采用ZigBee设备节点结合各类传感器完成对车辆内部和车辆地理信息的数据采集。通讯链路完成数据的有效传递,通过GPRS网络将温度和定位数据传递给远程监控中心。其中,监控中心主要由上位机软件和数据库构成。1、上位机是基于Visual Studio 2010平台用C#开发,通过Socket套接字技术接收GPRS模块发送的数据,然后存入到数据库;2、系统数据库采用Sql Sever 2008设计与构建,并通过ADO.NET技术完成对数据库的访问和连接;3、通信子系统采用数据报套接字UDP,通过GPRS网络实现远程无线通信,完成车载终端与服务器之间的数据交互;4、信息显示界面通过Winform窗体来呈现,从而实现了系统对输运车辆实时温度查询、地图查询、历史轨迹查询以及报警信息查询等功能。经过多次试验表明,系统运行稳定,在允许误差范围内实现了输运车辆实时定位以及温度监控的功能,达到了设计方案的预期效果。
[Abstract]:With the rapid development of economy in our country, the quality of life and health consciousness of the general population have been gradually improved, and the demand of consumers for fresh products (such as fresh vegetables, meat and eggs, etc.) has increased rapidly. However, Because the popularization and application of cold chain logistics technology in our country is not high enough, these foods are worn out too much in the process of logistics transportation, and the safety of food is not guaranteed. Therefore, in order to meet the needs of the present society, The research shows that the key of cold chain logistics is a set of complete temperature real-time monitoring system. In the past, most logistics enterprises used to adopt the traditional extensive management mode. The failure to achieve effective real-time monitoring and management of temperature has brought unnecessary economic losses to enterprises and become an unstable factor affecting the healthy diet of the general population. This paper designs a cold chain logistics remote monitoring system which integrates ZigBee network data transmission and GPS positioning. The system consists of three components, including vehicle terminal. Monitoring center and communication link. The vehicle terminal adopts ZigBee device node to complete the data collection of the vehicle interior and vehicle geographic information, and the communication link completes the effective data transmission. The temperature and positioning data are transferred to the remote monitoring center through GPRS network. Among them, the monitoring center is mainly composed of PC software and database. The PC is developed with C # based on Visual Studio 2010 platform. The data sent by GPRS module is received by Socket socket technology, and then stored into database. The database is designed and constructed by Sql Sever 2008. The database is accessed and connected by ADO.NET technology. The communication subsystem adopts Datagram socket, and realizes the remote wireless communication through GPRS network. The data exchange between the vehicle terminal and the server is completed. The information display interface is presented through the Winform form, thus realizing the real-time temperature query and map query of the transportation vehicle. Several experiments show that the system runs stably and realizes the functions of real-time positioning and temperature monitoring within the allowable error range, and achieves the expected effect of the design scheme.
