Mold positioning management based on RFID technology

This system uses RFID technology to systematically code and identify mold storage locations with RFID electronic tags, solving various problems such as registration errors, record loss, management confusion, and inconvenient search in traditional mold management, and achieving scientific and systematic Mold management. The main construction goals of this system are: to realize rapid entry and exit of molds and inventory management through system coding and identification; to quickly search for designated molds; to strengthen the anti-theft alarm mechanism of the warehouse Access Control system.

       Aiming at the management requirements for precise positioning of enterprise molds, this system adopts a combination of wireless WiFi technology, RFID technology, and service technology, and uses the RFID middleware system as a supporting platform to build a comprehensive mold positioning management solution. The main components are: Active Electronic tags, active readers and writers, locators, middleware, electronic tag issuance and management software, servers, positioning management software, etc.

       The specific application process of the RFID mold positioning system is as follows: The tag uses an ultra-high frequency anti-metal tag. Each tag is assigned a unique ID code, which corresponds to the mold one-to-one. The mold information is written into the chip, including the mold number, production date, and location. , type, processing materials, repair, maintenance and other contents, and upload them to the database. The surface of the label is made of high-strength Engineering plastic, which is resistant to pressure and impact. An anti-metal label is installed on each side of the mold; the mold is read through an ultra-high frequency antenna. Electronic tags, active RFID Readers and writers automatically read the elevator tags of the mold rack. The system automatically binds the mold position and uploads the data to the backend management system through the industrial control computer to achieve rapid warehousing; when leaving the warehouse, the tags are read through the antenna. , the active reader/writer reads the elevator tag, the system automatically releases the mold position, and uploads the data through the industrial control computer to achieve rapid delivery; during inventory, the inventory mold status is timely queried through the database system to understand the mold inventory.

       The main functions of this system are:

       1) Bind a locating card to the item. When warehousing, you can enter the item number, locating card number, item type, item description and other relevant information. The information will be reported to the host through the base station and then displayed in the item information column of the item management;

       2) Provide a variety of query methods, and you can query items by area, shelf number, item type, item number, location card number, maintenance status, storage time, etc.;

       3) Item positioning provides three positioning methods: item number positioning, item card number positioning and item type positioning. Enter the item number or card number or select the item type and click to locate. The card number bound to the located item can generate an audible and visual alarm. At the same time, the positioning information is displayed on the warehouse map. The audible and visual alarm information can be based on the location on the map and the positioning card. Quickly find located items;

       4) Item inventory can automatically count various types of items and quantities without manual operation;

       5) Outbound statistics include item number, item type, entry time, outbound time, destination and other information. You can query based on item number, item type, destination, and time;

       6) When items move from one place to another, the system will automatically change the area based on the location information transmitted from the positioning card, without manual processing.

       This system uses wireless radio frequency technology. All base station and positioning card information are automatically uploaded wirelessly. Information statistics can be completed without manual collection, truly realizing automated and intelligent management. Ordinary barcode technology cannot achieve positioning functions and requires Search one by one. This system can directly locate items when searching for them. Combined with map display and sound and light alarm system, it can promptly prompt the location of items and improve efficiency. The positioning card can define a variety of different states according to different sounds and lights. Each state It can represent different meanings of the item, such as missing accessories, to be maintained, under maintenance, maintained, etc.; when the item is moved, the trajectory of the item is tracked in real time and the current location of the item is automatically updated; during automatic business processing, it can be used for important The equipment is designated to be Stored in a designated storage area. When the tracked equipment moves out of the designated area without authorization, the system automatically issues an alarm message.

       In manufacturing enterprises, due to the wide variety of molds, the incoming and outgoing and usage status of abrasive Tools cannot be recorded in real time. Traditional paper records not only bring inconvenience to information retrieval, but are also error-prone. In addition, changes in mold storage locations lead to inaccuracies for future use. Inconvenient to find. The application of RFID technology can fundamentally solve these problems. By installing RFID electronic tags on the molds, each group of molds can be monitored in real time. The system can record the incoming and outgoing information of the molds and the usage status of the molds in real time to achieve automated mold warehousing management. .
