IceBox冰盒食记（获奖作品）——基于云开发CloudBase的微信小程序（一）
零：简介 Brief Introduction
本项目曾获2021中国高校微信小程序应用开发赛华南赛区二等奖，原本是冲省一国二的，可惜今年太玄学了哈哈哈，不过和舍友四个人一起熬夜两周肝项目的经历真的很美好，虽然结果不尽人意，但是过程还是很快乐的（尤其是本人一边肝项目一边考雅思一边搞互联网+的比赛，真是美好又痛苦的回忆）。

This project won the second prize in the South China Region of the 2021 China University WeChat Mini Program Application Development Competition, originally for the first prize at the provincial level and the second prize at the national level, but unfortunately this year we are unlucky LOL, but the experience of staying up all night for a fortnight with my four housemates for the project was really good. Although the result was not satisfactory, the process was still very happy (especially when I took the IELTS exam while doing the Internet plus competition and this project, which was a good and also painful memory).
一：项目介绍 Project Description
小程序简介 Introduction to the applet
冰盒食记，取自冰河世纪的谐音词。冰盒，指代冰箱，食记，指食物的保存记录。
冰盒食记小程序是一款以反食品浪费法为导向的应用。以冰箱存储为主体，通过及时管理冰箱达到减少食品浪费的目的。本小程序主要包含冰箱管理、购物清单、识别功能、资讯推送、食物科普、个人中心、卡牌收集七个模块。
The Icebox is an app that is oriented towards anti-food waste laws. With fridge storage as the main focus, it aims to reduce food waste by managing the fridge in a timely manner. This applet contains seven main modules: fridge management, shopping list, identification function, information push, food science, personal centre and card collection.
开发背景和意义 Background and significance of development
十三届全国人大常委会第二十八次会议表决通过了《中华人民共和国反食品浪费法》（以下简称《反食品浪费法》），透过这一事件看向本质，立法原因有迹可循。俗话说“民以食为天”，人们对吃食的追求逐渐提高，伴生的浪费现象也是触目惊心。作为一个农业大国，我们用全球9%的耕地、6%的淡水资源生产出来的粮食，养活了全球近20%的人口，虽然我们粮食连年丰收，但也因此纵容了人们对食品浪费的不重视。据中国农业科学院估算，粮食全产业链总损耗率约为12%，即每年粮食损耗高达7800万吨，其中因食品过保质期造成的浪费十分严重，仅进口食品过期扔掉的每年大约有30多亿美元，这一数据引起了我们的注意。
At the 28th meeting of the Standing Committee of the 13th National People’s Congress, the Anti-Food Waste Law of the People’s Republic of China (hereinafter referred to as the “Anti-Food Waste Law”) was passed. As the old saying goes, “Food is the key to life”, the pursuit of food has gradually increased and the accompanying waste is alarming. As an agricultural nation, we use 9% of the world’s arable land and 6% of its freshwater resources to produce food to feed nearly 20% of the world’s population, and although we have had bumper crops year after year, we have also indulged in a lack of attention to food waste. According to estimates by the Chinese Academy of Agricultural Sciences, the total loss rate of the entire food industry chain is about 12%, i.e. up to 78 million tonnes of food is lost every year, of which the waste caused by food that has passed its shelf life is very serious, with imported food alone being thrown away out of date at about US$3 billion a year, a figure that has drawn our attention.
节约粮食一直都是中华民族弘扬的传统美德，是对我们如今享受的幸福生活的敬畏之举。我们小组仔细研读了《反食品浪费法》，并以此为核心查阅了近几年来关于食品浪费的相关文献资料，其后还进行了一定的调研，总结得到当前食品浪费现象存在的重要原因是公众虽具有一定的节约粮食的意识，但部分人缺乏操作的相关知识和能力，如因工作学习繁忙而食品的购买日期，又或者不清楚食品的保质期从而没能如期吃完。我们分析了以上情况，研究开发出冰盒食记小程序，希望通过帮助用户管理冰箱、推送反粮食浪费有关资讯、科普食品保质期及相关知识，从而逐渐让用户在意识和行为上都能响应国家反食品浪费的号召，依法履行厨余垃圾源头减量的义务。
Food conservation has always been a traditional virtue promoted by the Chinese people as an act of reverence for the happy life we enjoy today. Our group has studied the Anti-Food Waste Law and reviewed the literature on food waste in recent years, followed by some research, and concluded that an important reason for the current food waste phenomenon is that although the public has some awareness of food saving, some people lack the knowledge and ability to do so, such as forgetting the date of purchase of food due to busy work and study, or they are not aware of the shelf life of food and therefore do not finish it on time. We have analysed the above situation and developed the Icebox Eats app to help users manage their fridges, push out information on anti-food waste and educate them on food shelf life and related knowledge, so that they can gradually respond to the national call for anti-food waste and fulfill their obligation to reduce food waste at source according to the law.

相似产品分析 Analysis
目前国内存在的以反食品浪费为主题的产品少之又少，比较出名的是“光盘打卡”小程序；同时以冰箱为主题的应用也是凤毛麟角，在华为市场上能搜到的只有“云冰箱管家”，微信小程序上也只有“喔冰箱”和“冰箱盒子”两个相关小程序。
At present, there are very few anti-food waste products in China, the most famous one being the “Finish eating” app. The only app available on Huawei Market is “Cloud Fridge Manager”. On Wechat Mini Program platform, we have “wow Fridge” and “Fridge Box”.
“光盘打卡”小程序直接与公益挂钩，通过打卡攒积分换奖品的方式吸引用户使用，在校园和城市中推广。但相对而言，基本上该小程序面向的用户基本为团体成员，由团体带动的打卡活动，对于个人，并没有太大的打卡意向和动力。同时，小程序中的光盘打卡并不能很好的区分盛有粮食吃完的空盘还是干净的盘子，这可能会造成有投机取巧的人为了兑换奖品而进行伪造打卡。
“喔冰箱”和“冰箱盒子”是比较简单的工具类小程序，具备抽象存储的特点，优点是可以通过扫码和识物来进行添加，但很多地方并不完善，例如添加物品后需要通过手动刷新来更新数据。且功能相对简单，且没有推荐保存日期。众所周知，造成保存不当过期的浪费大部分原因是不知道存储的大致期限，没有推荐日期不利于合理的食品存储。
“云冰箱管家”是一个比较成熟的、已经上线的app，采用语音输入的方式，比较便捷。但语音识别存在一定的误差，同时对于比较复杂的短语不能准确识别，例如“放入一个土鸡蛋”会被识别成“放入一只土鸡”，同时对于此软件，还存在数据前后不一致的情况。除此以外，不同时期购买的相同物品并不能相互区分开，除了记录下购买时间，并不能帮助用户区分。
The “Finish eating” app is directly linked to public welfare, attracting users to use it by exchanging points for prizes, and promoting it on campuses and in cities. However, the app is basically aimed at groups of people who are motivated by the group to punch cards, but there is little incentive for individuals to do so. At the same time, the app does not distinguish between empty and clean plates with finished food, which could lead to opportunistic people faking the cards in order to redeem prizes.
The “wow fridge” and “fridge box” are relatively simple tools, with abstract storage features, the advantage is that you can add items by scanning the code and recognising them, but many areas are not perfect, such as the need to update the data by manually refreshing after adding items. For example, after adding an item, you need to update the data by manually refreshing it. The functionality is relatively simple and there is no recommended save date. It is well known that much of the waste caused by improper storage is due to a lack of knowledge of the approximate storage period, and the lack of recommended dates is not conducive to sensible food storage.
The “Cloud Fridge Manager” is a relatively mature app that is already online and uses voice input, which is convenient. However, there are some errors in voice recognition, and complex phrases are not accurately recognised, for example, “put in a clay egg” is recognised as “put in a clay chicken”, and there are inconsistencies in the data for this app. In addition to this, the same items purchased at different times are not distinguishable from each other and do not help the user to distinguish between them other than by recording the time of purchase.
