The Internet of Things allows food to have an "identity card", but the problem of traceability system is still frequent, the main reasons are as follows:
First, immobile dead data
The traceability system of most enterprises, especially production enterprises, can only manage the batch of static data of food, not dynamic real-time data, and because the big data of the whole chain is not connected in series, the existing data cannot be cross-validated , It is impossible to truly achieve the source traceability, traceability, and traceability.
Second, separate technical issues
Most of China's traceability systems are developed by production and logistics companies. The internal traceability system of a single enterprise can only meet the needs of the company's traceability, forming a local traceability letter "island", which is difficult to meet the needs of the entire chain traceability information sharing; in essence, it is traditional centralized The problem that the database cannot expand the ecological technology.
Third, there are many standards and difficulties in systematic integration
At present, the construction of the traceability system in various domestic industries is still in its infancy, and no unified industry standards have been formed. The traceability system will have large differences due to the different requirements, designs, and choices of the traceability system, resulting in non-standard traceability content and inconsistent processes. 3. Problems with incompatible system software;
Fourth, the credibility of the traceability system needs to be improved
my country's relevant laws, regulations and supervision systems are not yet perfect, there is a lack of unified platform deployment and supervision, data lag and tampering are frequent, and market acceptance and consumer trust are low.
