Technical Field

The invention relates to the field of metering detection, in particular to a warehousing weight evaluation method and system based on the weight of dry matters of tobacco leaves.

Background

In the tobacco leaf circulation process, in order to ensure that both parties can smoothly carry out the handover, the tobacco industry formulates the tobacco leaf warehousing acceptance standard, and some industrial enterprises also formulate the tobacco leaf warehousing acceptance standard according to the self condition. In modern logistics tobacco storage, before the tobacco leaves are stored in a warehouse, the moisture content of the tobacco leaves stored in the warehouse and the weight of a tobacco leaf box (piece) are respectively detected, and the tobacco leaves are detected according to acceptance standards. As the existing tobacco leaf warehousing acceptance standard, the moisture content of the tobacco leaves and the weight of the tobacco leaf box (piece) are respectively accepted and judged. The weight of the tobacco leaves put in storage is light due to low moisture content of the tobacco leaves put in storage, so that the tobacco leaves do not accord with the existing storage standard and the storage handover is influenced. In the tobacco leaf storage, because the tobacco leaves absorb moisture and release moisture, the moisture content of the tobacco leaves is always in a dynamic balance process, and the weight of the tobacco leaves fluctuates along with the fluctuation of the moisture content of the tobacco leaves. In the process of warehousing, tobacco leaves with qualified warehousing weight are stored for a period of time, and the weight is randomly inspected again due to the fact that the tobacco leaves are dehumidified, so that the situation that the weight is unqualified is possible; the tobacco leaves with unqualified warehouse-in weight (light weight) can meet the acceptance standard again due to the fact that the tobacco leaves absorb moisture after being stored for a period of time. In order to solve the problem that the weight of the tobacco leaves is inconsistent with the warehousing evaluation due to water content fluctuation in the warehousing process, the warehousing and warehousing weights of the tobacco leaves are evaluated more scientifically, and a set of method needs to be designed to evaluate the weight of the tobacco leaves warehoused better.
