Embodiment Construction

[0036] Such as figure 1 As shown, a food safety traceability system based on the hidden Markov model monitors the production, transportation, storage and sales of food and collects data. The collected data is processed to establish a hidden Markov model, and then the The established hidden Markov model is used for cluster analysis, and corresponding measures are taken according to the results of cluster analysis to ensure food safety. The specific steps are as follows:

[0037] 1. Data processing

[0038] Before building the HMM model of time series data of food information, it needs to be preprocessed. First, standardize the data, and then use discrete symbols to represent the standardized data, and use the discrete symbols as the state observations of the model. Unify the given time series data of food information into a standard format, for example, the bacterial index of chilled fresh beef, the environmental index of the slaughterhouse, the temperature and location data ...

Abstract

The invention discloses a food safety tracing system based on a hidden Markov model, and belongs to the field of food safety. Through the monitoring and collection of production, transportation, storage and selling links of food, the system enables the collected data to be processed for building the hidden Markov model, then carries out the cluster analysis of the hidden Markov model, and taking corresponding measures to guarantee the safety of food according to the results of cluster analysis. The system can determine a fault link and a reason specifically according to the results of cluster analysis, so that the system can take the corresponding measures to guarantee the safety of food. For example, a relevant department of a government can take corresponding measures to achieve prevention and control according to the analysis results of safety data of food; an enterprise can adjust the production strategy according to the analysis results, thereby bringing more benefits for the enterprise; and a consumer can adjust the dietary according to the analysis results.

Description

technical field [0001] The invention relates to the field of food safety, in particular to a food safety traceability system based on a hidden Markov model. Background technique [0002] The food safety traceability system was first established and perfected by the European Union in 1997 to deal with the "mad cow disease" problem. It emphasizes the unique identification and process tracking of products, and implements ISO9001 and other quality control methods for tracking and tracing in all aspects of product production, transportation, storage, and sales. Once food safety problems occur, the source of food can be effectively traced. Recall unqualified products in time to minimize losses. [0003] The existing food safety traceability system has a single function, and food traceability applications can only complete the collection of data related to food and its raw materials, as well as some intuitive and simple traceability and information statistics applications. For ex...
