基于Android的小麦溯源系统的设计与实现
摘 要
越来越多的人对健康饮食的要求，使得粮食安全受到重视和广泛关注。人们对食物的需求也发生了翻天覆地的变化，从建国初期对食物数量上的需求逐渐转为新时代对高品质、健康、绿色、有机食物的要求。近年来粮食安全问题频发，广大消费者的身心健康以及国家未来经济发展都受到了前所未有的挑战。自古以来，我国便有“南稻北麦”的饮食习惯，小麦是我国重要口粮作物，种植范围遍布大江南北。本文以小麦为对象，在Android开源平台的基础上开发了一项小麦溯源系统，该系统可以记载小麦的生长情况并实时监测、小麦到面粉的加工过程、面粉的运输过程的信息，在移动端可溯源全过程，旨在维护粮食安全，让人民买的放心、吃得安心。本溯源系统以Android Studio为开发平台，利用Java编程，使用的数据库为Bmob,调用百度地图的应用程序接口和心知天气API，在企业进行面粉生产管理的同时，收集小麦从种植到加工成面粉这一过程各个环节的相关信息并上传至数据库。用户或相关部门人员利用手机扫描二维码即可实现溯源查询。本系统为消费者提供保障，使商品信息“透明化”；同时也为有关部门食品质量检测起到帮助作用，加强市场秩序监督管理。
DESIGN AND IMPLEMENTATION OF WHEAT TRACEABILITY SYSTEM BASED ON ANDROID
ABSTRACT
More and more people are demanding a healthy diet, which has made food security valued and widely concerned. The demand for food has also changed dramatically, from the demand for food in the early days of the founding of the Peoples Republic of China to the requirement for highquality, healthy, green and organic food in the new era. In recent years, food security problems have occurred frequently, and the physical and mental health of consumers and the future economic development of the country have been unprecedentedly challenged. Since ancient times, China has had a "southern rice and north wheat" diet. Wheat is an important ration crop in China, and its planting area is spread all over the country. This article takes wheat as the object, and designs an Androidbased wheat tracing system, which records and monitors the information of wheat growth process, wheat to flour processing, and the flour transport process. The whole process is traceable on the mobile terminal and is designed to maintain Food security allows people to buy and rest assured. With Android Studio as the development platform, Java programming is used, the database used is Bmob, and the application program interface of baidu map and Xinzhi weather API is called. While the company is managing flour production, it collects relevant information on all aspects of the process from wheat planting to flour processing and upload to the database. The user or relevant department personnel can scan the QR code using the mobile phone to realize the traceability query. This system provides guarantees for consumers and makes the product information “transparent”; at the same time, it also helps the food quality inspection of relevant departments and strengthens market order supervision and management.
