Warehouse management has always been a work that enterprises attach great importance to. Through the insight laboratory, Tianjin Little Bee found that the industry generally believes that a new generation of warehouse management systems represented by RFID technology is gradually replacing the traditional warehouse management model, relying on RFID automatic identification technology , Warehouse management will bid farewell to the problems of backwardness, extensiveness, and high error rate, and will bring a qualitative leap to the enterprise.
Generally speaking, the construction and operation of RFID warehouse management system is divided into 2 parts (software design, hardware erection and deployment):
One RFID warehouse management system software design
According to the actual needs of the enterprise, the design module is generally divided into the following aspects:
1. Warehouse management
When the goods enter the electromagnetic wave range of the RFID reader at the entrance of the warehouse, the RFID electronic tag will communicate with the reader and pass the goods information to the warehouse management system. The quantity and model of the goods are checked by comparison with the order. is it right or not. If there is any discrepancy, the system will transmit the data to the on-site staff for the next step of comparison work.
2. Outbound management
When the goods run to the door of the warehouse, use fixedReaderCommunicate with the tags, collect the RFID electronic tags of the goods out of the warehouse and send them to the warehouse management system to check whether they correspond to the plan. If there are errors, handle them manually as soon as possible. For a small amount of goods, you can use RFID handheld terminals to collect information from RFID electronic tags (handheld scanners or RFID tablet computers). When an error occurs, an alarm will be issued, and the staff should deal with it in time, and finally send the data to the warehouse management The system updates the database to complete the delivery.
3. Inventory management
According to the company’s inventory requirements, the data (including the quantity, type, stacking location, etc.) of the warehouse management system is retrieved, and the staff uses the RFID handheld terminal to scan the inventory (can be done at one time), and scan the recorded data at the same time It is transmitted to the back-end of the warehouse management system via wireless network and compared with the original data to find problems.
(Due to the unique non-contact reading of RFID (usually within a range of 1 to 2 meters), the goods information can be read quickly and easily, which can greatly improve accuracy compared with the traditional modes of inbound, outbound, and inventory counting. Rate and efficiency, but also save a lot of labor costs.
In addition to the above supportRFIDTechnology-specific modules, warehouse management system software also includes basic information management, system information management, data statistical analysis and other aspects.
2. Hardware deployment of RFID warehouse management system
Hardware deployment is related to the success or failure of the system. The warehouse management system that companies choose to use RFID technology is nothing more than to be more efficient and more accurate than before. There are many aspects involved in hardware deployment, such as the specific application environment of the enterprise, the location of the reader, how to place the RFID electronic tag on the goods, etc. These all need to be considered.
1. RFID reader deployment
Generally speaking, readers are divided into fixed readers and mobile readers. The fixed readers are divided into integrated readers and split readers. Here we choose a split reader.
In the part involving readers in and out of the warehouse, the RFID warehouse management system generally needs to install the reader antenna inside the door frame of the warehouse door, and generally install four antennas, and the reader is installed on the wall next to the door. When monitoring goods inside the warehouse, RFID reader antennas need to be placed on top of different areas, and RFID readers are also placed together.
2. Selection and placement of RFID electronic tags
As the only indication in the warehouse management system, electronic labels must be paid special attention to when placing them. In order to obtain the best reading and writing effect, the polarization of the label must be consistent with that of the reader.
At the same time, the choice of label material must be correct, such as: anti-metal label is used to mark metal goods. Non-anti-metal labels are used for goods like wooden boxes, canvas bags, plastic bags, cartons, etc. At the same time, pay attention to consistency when sticking labels and not sticking them indiscriminately.
The above two aspects are just two key aspects of hardware deployment. In fact, Tianjin Bee, based on years of service experience, shows that each different company involves many different problems when deploying hardware, which can be said to be diverse , When encountering this problem, designers need to communicate with the company in a timely manner and strive to solve some problems. Hardware deployment determines the effectiveness of the RFID warehouse management system and is the top priority in design.
The Internet of Things technology represented by RFID has penetrated into all aspects of many industries. Warehouse management is only one of the application directions. Tianjin Bee focuses on creating an efficient and accurate RFID warehouse management system, and firmly believes that it will be widely used in various industries. Among enterprises in various industries.
