Abstract

A food safety information service method based on the Internet of Things provided by the invention belongs to the field of Internet of Things services. Build multiple node servers in different geographic regions for the food information server. When there is a client accessing the domain name of the food information server in the region, through DNS domain name resolution, the IP of the corresponding node server in the region will be given priority to feedback to the client , for its access. This solution is low in cost, flexible in deployment, convenient in management and does not affect the access efficiency of users.

Description

A food safety information service method based on the internet of things

technical field

The invention relates to the field of Internet of Things services, in particular to a food safety information service method based on the Internet of Things.

Background technique

The Internet of Things food information service plays the role of information collection and distribution, and its core is the storage of information data. These data include static information, dynamic information, related sensor information, etc. of food. In practical applications, massive amounts of data will be stored on the food information server of the Internet of Things, and tens of thousands of visits will be handled every moment. Enterprises using a single information server need powerful hardware to support massive data storage and access. For this reason, there is an urgent need for a low-cost, high-efficiency method to deal with these problems.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned problems in the prior art and provide a food safety information service method based on the Internet of Things.

Achieved through the following technical solutions:

A food safety information service method based on the Internet of Things, including a food information server module for storing information corresponding to various foods; a node server module, divided according to regions, receiving and storing food corresponding information distributed by the food information server module ;DNS resolution module, used for resolution processing between domain name and IP; client module;

Proceed as follows:

1) The client module sends the domain name access service to the food information server module;

2) The DNS parsing module obtains the IP address corresponding to the client module to judge its area, and at the same time, analyzes the domain name in 1) and judges whether there is the node server closest to the client module in the area to which it belongs;

3) If yes, the DNS resolution module acquires the IP address of the nearest node server module in the area and feeds it back to the client module;

4) If not, the DNS resolution module directly obtains the IP address of the food information server module and feeds it back to the client module;

5) The client module accesses the IP address fed back in step 3) or 4) and performs information query.

Further, the food server module distributes food information to the node server module in real time.

Further, the node server module obtains and stores in real time the access records of clients in the area to the food information server module.

Further, the client is a PC or a mobile phone.

Beneficial effect

In the present invention, by building node servers in different areas of the Internet of Things food information server, it can effectively alleviate the problem of access overload brought to the server when users in different areas collectively access the Internet of Things food information server, and there is no need for existing The server hardware is upgraded, which saves costs and does not affect the query efficiency of users.

detailed description

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

The food information service based on the Internet of Things includes the food information server module, and its role in the food Internet of Things system is:

1) Storage point for static information of enterprises and products

a. Text - company introduction, product origin, specifications, etc.

b. Images - product thumbnails, company certification documents, etc.

c. Video - product promotion video, etc.

d. 3D-production/logistics environment, product panorama display

e. Various other information that can be expanded

2) Storage point for product dynamic information

a. Production events (farming, processing, packaging…)

b. Logistic events (warehousing, transportation, receiving...)

c. Sales events (split, sale...)

d. Scalable various events

3) The external portal of enterprise products on the Internet of Things

a. The only entrance to the static information of a single product

b. The only entrance to the dynamic information of a single product

4) Data basis for various applications

a. Traceability query

b. Supply chain analysis

c. Regulatory Data Submission

d. Scalable various other queries

It also includes a node server module, which is divided into regions and used to receive and store food corresponding information distributed by the food information server module in real time, or record and store food-related information accessed by the food information server in the region.

The DNS resolution module is used in the resolution processing of domain names and IP addresses. The client for accessing the food information server can be a PC or a mobile phone.

In this embodiment, the steps for the client to access the food information server are as follows:

1) The client module sends the domain name access service to the food information server module;

2) The DNS parsing module obtains the IP address corresponding to the client module to judge its area, and at the same time, analyzes the domain name in 1) and judges whether there is the node server closest to the client module in the area to which it belongs;

3) If yes, the DNS resolution module acquires the IP address of the nearest node server module in the area and feeds it back to the client module;

4) If not, the DNS resolution module directly obtains the IP address of the food information server module and feeds it back to the client module;

5) The client module accesses the IP address fed back in step 3) or 4) and performs information query.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, anyone familiar with the technology can think of changes or replacements within the technical scope disclosed in the present invention All fall within the protection scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of claims.

Claims (4)

1. a kind of food security information method of servicing based on Internet of Things, it is characterised in that including
