The Food Safety Warning System For Mobile Terminal

Nowadays,with the increasing of people's living standard,the problem of food safety is becoming more and more serious.Food safety problems are mainly embodied in: Firstly,food storage environment problems cause food to become bad.Secondly,food shelf life expire or the qualification of enterprise and production environment have problems.Thirdly,food enterprises can not find safety problems in time.The food safety warning system which this thesis describes monitors the food from many aspects to to solve these problems.When the problem is found,the system will produce warning information in time,so that users know the problem of their products immediately by the system,thereby avoiding the problem of food safety.Firstly,the thesis discribe that we use the temperature and humidity sensors to monitor the food storage environment,the temperature and humidity sensors can collect temperature and humidity data of the storage environment,the collected data is stored in the server.When the user want to check the storage environment,the data of temperature and humidity will be transfered from the server to the mobile terminal and displayed in the form of graphics.At the same time,when the temperature and humidity of the collected data is found to be abnormal,the system will produce early warning information to inform the user.This will be able to solve the problem of food storage environment which will lead to food safety problems.Secondly,it records all information of food and food enterprises as much as possible.The information of food includes the date of purchase,shelf time,purchase and shipping information,etc..The information of food enterprises mainly includes the enterprise quality information,enterprise personnel qualification,disinfection of kitchen and kitchen waste recycling information and so on.All information will be checked everyday,it finds expired data or data exceeded the range of user settings,the system will produce warning information immediately and inform the user in time.In this way,it can effectively monitor the food and the information of food enterprises,thereby avoid producing the problem of food and food enterprises.Finally,the system thesis describes uses the Android push message technology to solve the problem that enterprise can not find the food safety and enterprise problem in time.It is the main reason for the system to be based on the mobile terminal.When the server finds any abnormal data,it will produce warning information immediately,and will send the warning information to the client.Then,the user will receive early warning information on the mobile terminal.By looking through the warning information,the user can know the problem of food and enterprise in time,and then avoid producing the food safety problem.In thesis when users use the system they will passively received warning information if the food storage environment changes beyond the value user setted,or the materials of food is about to expire,or the document and information of enterprise needs to be updated.Users can also check the problem the problem of food and enterprises initiatively by the system.The system will help users avoid the problem of food safety in time.The system this thesis describes is an innovative application software.It uses the Notification Service of Android system to warn users that their products have problems.It can let the user find the food security hidden danger passively and immediately.It allows users to easily monitor the temperature and humidity of food safety information and other security information by the system.In view of the problem that the manual input text inefficiently on the mobile device,the system uses the technique of two-dimensional code scanning as far as possible to replace the manual input text.The system allows users to add or query information efficiently.So,they are the innovations of the system.
