Problems solved by technology

Such enterprises do not have computer automation systems connected with ONS (DNS), or have the ability to develop such systems;
[0004] 2) Due to the characteristics of food production and process, food analysis data in ONS (actually NAPTRRR of DNS server) results in a large number of useless analysis records;
[0005] 3) The use of NAPTR RR will have an impact on the performance of the DNS server, and the type-level data will increase the overhead of the DNS cache

Embodiment Construction

[0020] The present invention will be further described in detail according to the examples below.

[0021] The food coding logo used in this scheme is composed of the combination of GS1Identification Key, as follows:

[0022] 01 GTIN-14 10A 1 -A j(j≤20) 91 R

[0023] The meanings of the various parts that make up the logo are expressed as follows:

[0024] (1) GTIN: 14-digit object type code;

[0025] (2) LOT: batch or serial number with 1 to 20 digits and letters, variable length;

[0026] (3) R: 1 digit, used to identify the length of the vendor identification code in the GTIN.

[0027] The identification of the item is formed by combining GTIN (Global Trade Item Number, Global Trade Item Code) and batch or serial number (Batch / Lot Number), while using GLN (Global Location Number) as the location identification of the business point, SSCC (Serial Shipping Container Code) as the packaging identification. The advantage of this is that it can be compatible with various o...

Abstract

The present invention provides a food identification analytical method based on the internet of things, belonging to the internet of things service field. An internet of things analysis service module is provided to be a service program based on Web Services and configured for the conversion work from food identification to the food circulation node enterprise server addressing. The food identification analytical method based on internet of things is simple to operate, high in query efficiency and convenient to maintain and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the field of Internet of Things services, in particular to a food identification analysis method based on the Internet of Things. Background technique [0002] Food identification needs to resolve the service to complete the addressing to the service resources. Object name resolution service (ONS) is to realize the conversion of Identification Keys to full domain name (FQDN) and perform domain name resolution service (DNS) through the application of unique character string (AUS). The specific address data is stored in the name authoritative pointer (NAPTR) type resource record of the DNS server in the form of a uniform resource locator (URL), and this data is provided to the ONS client to complete the item corresponding information discovery service (DS), information service (IS) and other service resource addressing and access. The solution given by ONS actually uses DNS technology to complete item addressing at the category...
