Tobacco handling and storage system

Abstract

The invention discloses a tobacco handling and storage system which is composed of a perception card, a card reader, a handheld terminal, a common platform and tobacco handling and storage system software. By using the perception card, multiple sensors are integrated on a device layer to collect sensing information. A device perception layer has a clear and simple structure and uses a unified data transfer protocol. The perception card is wirelessly connected with the fixed card reader, so that device layout and construction are simple. According to the existing scheme, data collected by the sensors are sent to the common platform through a gateway; the platform carries out unified operation and management; through a device management function of the platform, whether a device is damaged and other problems can be accurately and timely found; through the perception card, real-time alarm can be carried out for a tobacco assembly error and a handling route error to reduce the error rate in a operation process; all collected data are provided for the tobacco handling and storage system through a platform publishing service; and monitoring and management are carried out on the whole processes of tobacco handling and storage.

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
