Each piece of data can be stored in Hadoop. Here, Hadoop is configured to process data of tens to hundreds of gigabytes or more at low cost regardless of the data structure, and can be implemented as a MapReduce framework.

In the present embodiment, the distribution environment monitoring data includes temperature, humidity, time, and position information measured for each of the identifiers (sensor IDs) 1 to 9 of the first sensors 10d attached to the nine boxes, As shown in FIG.

On the other hand, in the present embodiment, it is explained that the APC 4 measures the temperature and humidity of the agricultural products when the agricultural products are delivered from the APC 4 for convenience of explanation. However, the present invention is not limited to this. It is needless to say that the temperature and humidity of agricultural products can be measured and the measured temperature and humidity data can be used.

11, if the position of the first sensor 10d continuously changes and approaches the destination address (Loc-wholesaler A) and does not change any more, the agricultural data processing system 30 sends " 'Event.

When the wholesaler arrival event is detected, the distribution environment monitoring process ends. When the distribution environment monitoring process ends, the agricultural product data processing system 30 analyzes the temperature and humidity data collected through the distribution environment monitoring. That is, the agricultural product data processing system 30 estimates the expiration date by referring to the pattern database (Pattern DB), and calculates the expiration date for each sensor. The shelf life of each sensor is limited to the shelf life of agricultural products packed in box (first standard packing material) with the first sensor attached.
