A tobacco storage system

Abstract

A tobacco leaf transportation and storage system, which consists of a sensing card, a card reader, a handheld terminal, a common platform, and tobacco leaf transportation and storage system software. The sensing card is used to integrate a variety of sensors at the equipment layer to collect sensing information. The structure of the equipment perception layer is clear It is simple and adopts a unified data transmission protocol. The sensing card establishes a connection with the fixed card reader through wireless, so the layout and construction of the equipment are relatively simple. The existing solution collects sensor data and sends it to the common platform through the gateway, which is operated and managed by the platform in a unified manner. The device management function of the platform can accurately and timely find out whether the device is damaged or not. Through the sensing card, it can also give real-time alarms to tobacco leaf assembly errors and transportation route errors to reduce the error rate in the operation process. All collected data is provided to the tobacco leaf transportation and storage system by the platform publishing service, realizing the whole process monitoring and management of tobacco leaves in storage and transportation.

Description

technical field [0001] The invention belongs to the intersecting fields of tobacco storage and transportation and the Internet of Things, in particular a tobacco leaf transportation and storage system. Background technique [0002] At present, most of the tobacco leaf systems mainly stay in the monitoring aspect. After the tobacco leaves are purchased and stored, the water weight loss is 0.5% to 2%. Tobacco leaves are oxidized during storage and generate heat. Due to the poor thermal conductivity of tobacco leaves, the heat generated by alcoholization is mostly accumulated in the cigarette pack and the smoke pile. Tobacco leaves change in weight, heat, moisture absorption capacity, and color during storage. During the storage process, tobacco leaves consume oxygen and release carbon dioxide; some proteins and amino acids are deaminated to release ammonia; pectin is decomposed to release methanol; some organic acids are oxidized to release carbon dioxide and other reaction...

AI Technical Summary

Problems solved by technology

[0003] The existing scheme has the following disadvantages: the existing scheme uses a single independent sensor to collect a kind of monitoring data, and it is necessary to use multiple sensor devices to collect multiple data

The system becomes more complicated, and there is no unified standard for the transmission protocol of sensors at present. The impossibility of consistent transmission protocols of sensor devices will bring a lot of compatibility work

In addition, the sensor uses the RS485 bus to establish a connection with the wireless gateway, so it brings great difficulties in the layout and construction of the equipment.

Existing solutions collect sensor data and directly send it to the corresponding system. There is no unified platform for unified operation and management. Whether the equipment is damaged cannot be detected in time, and it is easy to cause missed or false positives), and it is impossible to form an operating system

For this reason, the existing scheme cannot be linked with tobacco leaf logistics, and cannot meet the whole process monitoring of tobacco leaves during storage and transportation
