1. Industry background analysis
Tobacco is a fast-moving consumer product and belongs to a fast-moving industry. Various tobacco companies are competing fiercely and rushing to occupy terminal stores. The speed of circulation is the most important factor in the market competition, and the management of the warehouse is the most direct factor that determines the speed of circulation. Now, many tobacco companies are facing the following difficulties in warehouse management:
(a) Slow inventory speed: The company checks the actual quantity of goods in stock with the quantity recorded in the custody account. This method is time-consuming and labor-intensive, and errors are prone to occur during the inventory process, resulting in untimely production scheduling and affecting work schedule.
(b) Difficulty in real-time supervision: The number of warehouse managers is limited, and they cannot fully control warehouse information in real time, which may easily cause problems such as loss of warehouse tobacco, packet loss, and misplacement.
(c) High inventory costs: In the face of increasing warehouse scale, complexity, and throughput, and increasing labor costs, companies need to reduce inventory costs through tighter technology integration.
The Little Bee RFID tobacco warehouse system solution is mainly for small and medium-sized enterprises to solve the problems of manual sorting confusion, slow inventory speed, small storage area, etc., and the warehouse’s arrival inspection, warehousing, outgoing, inventory inventory, query and other operations. The data is automatically collected.
2. Technology Application
RFID is a non-contact automatic identification technology that uses radio frequency signals to automatically identify objects to be identified. The RFID system includes two parts, an electronic tag and a reader. The electronic label is the data carrier of the radio frequency identification system, and the detailed information of the article is entered into the electronic label, which is the identity card of the article. The RFID reader communicates wirelessly with the RFID electronic tag through an antenna to realize the reading and writing operations of the tag identification code and memory data.
The Little Bee RFID tobacco warehouse system solution consists of two sub-systems, a software system and a hardware system, which closely connects the technology and the business of warehouse management, and inspects the arrival of the warehouse, warehousing, outgoing, inventory counting, and inquiries. The data of the operation link is automatically collected.
Three. Solution
The Little Bee RFID tobacco warehouse system solution uses RFID technology to automatically collect data from various operations such as warehouse arrival inspection, warehousing, outgoing, inventory counting, and query, to ensure the speed and speed of data input in all aspects of warehouse management. Accuracy, to ensure that companies grasp the real data of inventory in a timely and accurate manner, and reasonably maintain and control corporate inventory.
1. Storage
A fixed reader is placed at the door of the warehouse, and after receiving the warehousing order, the products with RFID electronic tags are put into the warehouse according to the rules. When a product with an RFID electronic tag enters the electromagnetic wave range of the fixed reader, it will automatically activate and communicate with the fixed reader to collect RFID tags. After completion, compare it with the tobacco order and check the goods information.
2. Delivery
When leaving the warehouse, push the goods to the door of the warehouse, and use the fixed reader to communicate with the goods with electronic tags to collect the RFID electronic tags of the goods out of the warehouse. After completion, check with the tobacco outgoing list to check the goods information .
3. Inventory
After having the inventory plan, use the RFID handheld terminal to carry out the inventory scan of the goods, inventory the tobacco information, transmit it to the back-end database through the wireless network, and compare it with the information in the database, and generate the difference information and display it on the RFID handheld terminal in real time to provide the inventory. The staff checked and finally completed the inventory.
4. Query Statistics
Warehouse management personnel can perform query and statistical operations on the information in the system database, query the situation of a single or a batch of goods, and query and fuzzy query according to any field set. The staff can clearly understand the unit, specification, name, storage situation, transfer history, statistics of various types of goods, effective goods information, etc. through the system.
5. Interface and data interaction with other systems
The Little Bee RFID tobacco warehouse system reserves the company’s other own management system interfaces, such as the company’s ERP system, financial data system, etc. Through the company’s system interface, it can be seamlessly connected, supports data import and information exchange, and can be connected with other companies’ self-owned management systems. A management system directly performs batch data exchange processing.
4. Hardware products
1. Electronic label
Electronic tags have passive electronic tags and activeelectronic labelTwo kinds. Passive electronic tags do not have a built-in battery. When outside the reading range of the reader, the electronic tag is in a passive state and cannot actively communicate with the reader; when it is within the reading range of the reader, the electronic tag is sent from the reader It extracts the power needed for its work from the radio frequency energy, and communicates with the reader. The energy of the active electronic tag is provided by the battery, has a long reading distance, and can actively send signals to communicate with the reader.
2. RFID Reader
RFID readers include handheld readers (PDAs) and fixed readers. The principle is to carry out wireless communication with the RFID electronic tag through the antenna to realize the reading and writing operation of the tag identification code and memory data. Fixed readers are generally installed at the door of the warehouse; handheld readers can move in the warehouse, receive signals from active electronic tags in real time, and transfer the received data to the background management system.
3. Antenna
ReaderAntennas generally require the use of directional antennas, which can be divided into two types: combined and separate. Multi-assembly means that the antenna and the chip are integrated together, while sub-assembly means that the antenna and the chip are connected through a coaxial line. Generally speaking, the design requirements of the reader antenna are lower than that of the tag antenna.
5. System benefits
The little bee RFID tobacco system solution can effectively achieve:
(1) Fast reading: The effective recognition distance of data reading is larger, the recognition speed is faster, the amount of information read is large and detailed, and multiple tags can be processed at the same time to realize batch recognition.
(2) Large capacity and long life: RFID tags can be expanded to dozens of K in storage capacity according to user needs, have low environmental requirements, can be used repeatedly, are not easily damaged, wear-resistant, safer, and have a long service life.
(3) Quick inventory: A new inventory mode is provided for the tobacco warehouse, which reduces the labor intensity of operators, greatly improves the efficiency of cargo inventory and the sorting of wrong goods, and makes cargo search faster and more convenient.
(4) Dynamic real-time communication: The tag communicates with the reader at a frequency of 50-100 times per second. As long as the object attached to the RFID tag appears within the effective recognition range of the reader, its position can be dynamically tracked And monitoring, effectively prevent the loss of goods, misplacement and other problems.
