【摘要】：近年来,农产品质量安全已经成为人们关注的焦点。构建农产品检测信息共享平台,实现检测信息在农产品生产企业、检测机构、监督机构和消费者之间安全可控的共享,有助于提高农产品质量安全水平。本研究主要内容包括以下三个方面：(1)构建了农产品检测信息共享数据库。通过对农产品检测信息共享平台的分析,设计了农产品生产企业、检测机构、监督机构、管理员和消费者各个子系统所需的数据表,如用户账号信息表,农产品生产企业信息表、检测机构信息表、第三方检测信息表、自检信息表、抽查信息表和日志记录表等。(2)设计开发了农产品检测信息共享管理系统。系统分为管理员子系统、监督机构子系统、检测机构子系统、农产品生产企业子系统和消费者子系统。管理员主要负责用户的审核和系统的日常管理；监督机构可以将抽查的检测信息录入到系统,并选择是否共享抽查信息,也可监督农产品生产企业的检测信息；检测机构主要完成农产品生产企业的检测预约,并将检测信息返回给生产企业；农产品生产企业根据自己的检测需求选择检测机构,并在网上完成预约,根据检测机构的时间安排将样品送至检测机构,直到检测机构返回检测结果,生产企业也可将企业内部自检信息录入系统,并选择是否共享,生产企业还可以利用系统提供的溯源管理功能实现信息的共享；消费者可以浏览查询生产企业或者监督机构发布的共享信息,从而了解当前的农产品质量安全现状,也可以通过扫描农产品包装上的二维码获取农产品的溯源信息。(3)设计开发了基于Android手机的农产品信息管理客户端。Android客户端实现的功能有用户的注册登录,企业信息、产品信息、加工信息和检测信息的增删改查。为了保证检测信息的安全性,在信息传输过程中使用DES进行加密。基于Android的信息管理客户端能够自动获取系统的时间,减少录入信息时的操作步骤,保证了信息输入的准确和高效。最后,设计了网站的整体架构,搭建了测试环境,使用Nginx实现了系统的负载均衡,测试结果表明,该架构满足设计要求。
[Abstract]:In recent years, the quality and safety of agricultural products has become the focus of attention. Building the information sharing platform for agricultural products detection, realizing the safe and controllable sharing between the inspection information in the production enterprises of agricultural products, the inspection agencies, the supervision organizations and the consumers, will help to improve the quality and safety of agricultural products. The main contents of this study include the following three parties (1) the information sharing database of agricultural products detection is constructed. Through the analysis of the information sharing platform for agricultural products detection, the data tables for the agricultural products production enterprises, inspection organizations, supervision institutions, administrators and consumers are designed, such as the user account information table, the information table of agricultural production enterprises, and the information table of the inspection organization, Third party detection information table, self-examination information table, check information table and log record table, etc. (2) the management system of agricultural product detection information sharing is designed and developed. The system is divided into the administrator subsystem, the supervision institution subsystem, the inspection organization subsystem, the agricultural product production enterprise subsystem and the consumer subsystem. The administrator is mainly responsible for the user's audit. As well as the daily management of the system, the supervisory organization can enter the inspection information into the system, choose whether to share the information of the spot inspection, and also supervise the detection information of the agricultural production enterprise; the inspection organization mainly completes the inspection reservation of the agricultural production enterprise, and returns the detection information to the production enterprise; the agricultural production enterprise is the root of the production enterprise. According to its own testing needs, the inspection organization is selected, and the reservation is completed on the Internet. According to the time arrangement of the inspection organization, the sample is sent to the inspection organization, until the detection organization returns the result of the detection. The production enterprise can also input the internal self inspection information into the system, and choose whether to share it, and the production enterprise can also use the traceability pipe provided by the system. In order to realize the sharing of information, the consumer can browse and query the shared information issued by the production enterprise or the supervisory organization, so as to understand the current situation of the quality and safety of agricultural products, and to obtain the traceability information of agricultural products by scanning the two-dimensional code on the agricultural product packaging. (3) the agricultural product information based on the Android mobile phone is designed and developed. The functions of managing client.Android client are registered login, enterprise information, product information, processing information and detection information. In order to ensure the security of detection information, DES is used to encrypt the information in the process of information transmission. The information management client based on Android can automatically obtain the time of the system and reduce the time of the system. In the end, the whole architecture of the website is designed, the test environment is built, and the load balance of the system is realized by using Nginx. The test results show that the architecture meets the design requirements.
