【摘要】：随着社会经济的发展,人们的生活水平日益提高,对食品、奶制品以及部分药品的新鲜度的要求越来越高。运输过程监控不及时和车辆调度不完善往往会使货物品质下降,运输成本升高。因此,对冷链物流运输环节进行实时监控与调度在运输过程中发挥着至关重要的作用。对冷链运输过程进行实时监控,可以确保货物的品质;其次企业根据客户需求使用优化算法对运输车辆进行调度,寻找运输过程中的最短路径可以降低运输时间和距离从而降低运输成本。在对冷链物流车辆监控及调度系统研究背景、意义以及国内外研究现状的基础上,本文主要设计与实现了冷链物流车辆监控及调度系统上位机部分,同时对系统中车辆调度优化算法进行了研究。车载终端将采集来的温湿度、地理位置等信息通过无线传输模块上传到监控中心,上位机部分通过编写的Java脚本对服务器端口进行监听,读取传感器上传的数据并录入数据库。系统将采集来的温湿度、车辆地理位置等信息发布在网站上,并通过百度地图API将电子地图嵌入到网页中,从而使车辆的地理位置显示在地图上。当用户需要查看数据时可登录网站对车辆信息进行跟踪查看;系统中调度优化算法方面,本文在传统的蚁群算法的基础上进行了改进,运用改进的蚁群算法对冷链物流实例进行求解,在配送前根据客户信息求出最优的配送路径,从而降低配送过程中产生的成本。冷链物流车辆监控及调度系统采用B/S网络体系结构设计。使用Apache服务器,后台数据库是由瑞典MySQL AB公司开发的MySQL数据库,系统的开发环境为Zend Studio,地图为百度地图。系统经过测试后能稳定运行,实现了预期的车辆实时定位、运输车辆货物温湿度实时显示、数据超限报警、车辆调度以及信息管理等功能。
[Abstract]:With the development of society and economy, people's living standard is increasing. The demand for freshness of food, dairy products and some medicines is getting higher and higher. The poor quality of goods and the increase of transportation cost are often caused by the untimely monitoring of the transportation process and the imperfect vehicle scheduling. Therefore, the real-time monitoring and scheduling of the cold chain logistics transport link is carried out. In the process of transportation, the real-time monitoring of the cold chain transportation process can ensure the quality of the goods. Secondly, the enterprise uses the optimization algorithm to dispatch the transportation vehicles according to the customer's needs. On the basis of the research background, significance and research status at home and abroad, this paper mainly designs and implements the upper computer part of the cold chain logistics vehicle monitoring and dispatching system, and studies the optimization algorithm of vehicle scheduling in the system. The line transmission module is uploaded to the monitoring center, the upper computer monitor the server port through the written Java script, read the data uploaded by the sensor and enter the database. The system releases the information on the temperature and humidity, the location of the vehicle and other information on the web site, and embeds the electronic map into the web page through the Baidu map API. The location of the vehicle is displayed on the map. When the user needs to view the data, the web site can track the vehicle information. In the system scheduling optimization algorithm, this paper has improved on the basis of the traditional ant colony algorithm, using the improved ant colony algorithm to solve the cold chain logistics example, and according to the customer before distribution. The information seeks the best distribution path, thus reducing the cost produced in the distribution process. The cold chain logistics vehicle monitoring and dispatching system adopts the B/S network architecture design. Using the Apache server, the backstage database is the MySQL database developed by Sweden MySQL AB company, the opening environment of the system is Zend Studio, and the map is the Baidu map. After testing, the system can run steadily, realizing the expected real-time positioning of the vehicle, real-time display of temperature and humidity of the goods of the transport vehicle, the alarm of overlimit of data, vehicle scheduling and information management.
