Research And Design Of Food Safety Transaction Supervision Terminal Based On Two - Dimensional Code

Food safety problem is the widespread subject concerned by public in recent years, which is related to the people’s health and life safety, related to the economic development and social stability. Due to the national food safety traceability system is not perfect, it is difficult to achieve overall monitoring information flow management and monitoring the management information can not be passed to the hands of ordinary consumers. This paper studies the current status of food safety traceability at home and abroad, combined with the pork products traceability process of Xi’shan District in kunming, designs a food safety supervision terminal unit. Takes advantage of existing mature two-dimensional code recognition technology, WIFI wireless network technology and LED electronic display technology, gives a set of information collection, processing and display functions in the integration of food safety supervision terminal solution. Through the food safety regulatory trading terminal conduct the illegal business behavior of market vendors, formal market order and safeguard the legitimate rights and interests of consumers.The thesis research is as follows:1Analyzes pork products process in the supply chain on the basis of food safety traceability systemIntroduces the present situation of food safety traceability system both at home and abroad, pork product safety traceability of the Xi’shan District in kunming as an example, analyzes the pork products production process in the supply chain.2Automatic identification technology introduction and application of two-dimensional code in food safety traceabilityIntroduces the comparison with RFID and two-dimensional code of automatic identification technology, according to the pork production process of Xi’shan District, identifies market traceability scheme based on two-dimensional code.3Design and implementation of food safety regulatory trading terminalDesigns various functional components of food safety supervision transaction terminal device, writes the corresponding control code. Transaction monitoring terminals using Android phones collect two-dimensional code data to the micro controller via WIFI wireless, and then LED electronic display shows, and for basic information collection, information processing and information display functions.4According to the function of the food safety trading regulation terminal design android source software implementation processBased on the android system develops food traceability software include meat and poultry, vegetables and aquatic products, to achieve full traceability of food information.
