Problems solved by technology

However, the traceability query based on the food safety information database is still not widely used. On the one hand, the collection of food information in a complex environment is not perfect, and on the other hand, a perfect and convenient data query method has not yet been formed in this field.

Embodiment Construction

[0035] The present invention provides a visual two-dimensional code food information traceability method. In order to make the advantages and technical solutions of the present invention more specific, the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0036]The overall process realized by the present invention is: a food production enterprise adopts a unified coding rule to generate a food information traceability code, and encodes the traceability code, material, and product code of the food, the code, name, address, contact number of the enterprise, and the geography of the enterprise and place of origin The location coordinates and other information are uploaded to the statistical geographic information system to form the origin traceability information database, and at the same time, the enterprise-side two-dimensional code label of "food quality and safety information + origin geographical coordinates" is genera...

Abstract

The invention discloses a spatial visualization revealed two-dimension code food information tracing method which comprises generating enterprise terminal two-dimension code labels comprising food quality and safety information and producing area geographic positions; adopting a label recognizer with a global position system (GPS) to scan two-dimension code labels in food storage, transportation and sale links, storing obtained geographical coordinates and link information in a data base and generating retail terminal two-dimension code labels; conducting statistics and platform building: adopting a statistic geographic information system (GIS) TO analyze and process data and building a visualization food information exhibiting and inquiring platform; and tracing: scanning the enterprise terminal two-dimension code labels and / or the retail terminal two-dimension code labels by using a mobile terminal and obtaining corresponding label information. The method enables statistical indexes to be overlapped and displayed on an electronic map, achieves perfect combination between statistical information and geographical location information, reveals food quality safety information in a visual mode and provides and effective mode for collection, statistics and analysis of safety food information.

Description

technical field [0001] The invention relates to the fields of communication technology and computer application, in particular to a method for traceability of two-dimensional code food information in spatial visualization. Background technique [0002] Two-dimensional barcodes, referred to as two-dimensional codes, were produced in the late 1980s. After 20 years of development, two-dimensional codes have played a huge role in information management and information exchange in traditional industries. A two-dimensional code is a barcode that records data information with black and white graphics on a plane according to certain rules. In coding, the concepts of "0" and "1" bit streams that constitute the internal logic basis of the computer are used, and several geometric shapes corresponding to binary are used to represent text and numerical information. Two-dimensional code has the characteristics of high information density, large information capacity, strong anti-interfere...
