1. Project background

The tobacco industry is a fast-moving consumer product that belongs to the fast-distribution industry. In the competition of major tobacco companies' homes, in addition to the brand's high, medium and low-end divisions, terminal distribution and other channels are the most fierce competition. Various tobacco companies have tried their best to improve management level, optimize business processes, improve the market competitiveness of enterprises through some high-tech methods, and enhance their resilience. They hope to remain invincible in the market competition.

Hui Enterprise IOT Technology adopts RFID technology and combines the status quo of tobacco companies. To achieve the automation of tobacco storage and efficient management of the warehouse. The system uses middleware as a support platform, attaches RFID tags to cigarette crates, trays and shelves, installs an RFID access control system at the receiving place, and sends the actual receipt and storage information to the back end, which is arranged by the back-end system. At the same time, the vehicle computer terminal is installed on the forklift, the RFID reading and writing device is connected, the information of the front-end system and the back-end system is transmitted through the wireless local area network, and the data exchange and update is realized, and the system locates the forklift position in real time, and conveniently dispatches the forklift.

1.1 Current status

First of all, the current tobacco management generally has the problem of inefficient inventory, from the single product, the box, to the tray are manually entered information. The efficiency of some links is low, and the informatization of the whole process is not high;
Secondly, the traditional bar code system has obvious shortcomings, such as easy pollution, damage, need to stop waiting for scanning one by one, etc., the batch reading efficiency is not high, can not meet the fast and accurate needs.

In response to the above problems, we use RFID technology, namely radio frequency technology. And as a more feasible solution. The digital management system is used to carry out the overall integration of warehouse management, which is the digital warehouse management system of tobacco companies. It not only meets the requirements of the distribution operation mode in modern logistics, but also applies to large-scale busy logistics and distribution, ensuring high-quality data exchange in the supply chain. At the same time, through tracking from the production line of the enterprise and enhancing its transparency in the supply chain, It can effectively contain or even eliminate extracorporeal circulation, and can play a huge role in the management of tobacco monopoly.

2, system composition

2.1 System composition

Hardware system: RFID tags, readers, antennas, on-board computer terminals, and wireless LAN devices, application servers;
Software system: database and process packages such as warehousing, inventory, forklift positioning/scheduling;
Middleware system: It is the operation support platform of the whole system, with functions of data collection, filtering, sorting, encapsulation and forwarding.

2.2 Main hardware device functions

RFID tag: A logistics information carrier for storing information about packaging boxes, pallets, etc.
Fixed reader: The data acquisition device of the tag is used to collect the data information inside the electronic tag and transmit the read tray information to the upper system for corresponding processing.

Handheld Reader: Reads label and barcode information for manual stacking. First, the tray information is read, and the barcode information on each cigarette of the stack is read one by one, and the information is uploaded to the background system for association in the database.
