Description

RFID based yard management system and method thereof {Management System for a things of construction in the field}

RFID is actively used in manpower, logistics, and material management, and overseas research and application are underway. In particular, in Japan, various fields such as surveying, construction, transportation, maintenance, etc. Laboratory and application. In particular, R & D and commercialization of logistics, material management, facility management, and maintenance are actively underway, especially in general construction companies. Future-oriented field management system using IT technology is developing with the convergence technology in the field management items such as process / cost management, work management and resource management.

Radio Frequency Identification (RFID) is a technology that provides location, remote processing, management, and information exchange services by collecting, storing, processing, and tracking information / ID and surrounding environment information from a tag attached to an object by using radio waves. It consists of identification code, tag, reader, middleware, application service platform, etc., interlocked with wired / wireless communication network, and complements barcode to enable intelligent networking of distribution and logistics, and innovation of security, safety, and environmental management. In addition, it is emerging as a core technology that can expand the information horizon by synchronizing the information with the reality.

If you go to a small construction company, you can see that the materials are still cluttered. This is a big difference from manufacturing distributors who have been working on logistics materials management. Measures and phenomena are priorities for improvement, and these sites often rely on a handbook (individual) to make purchases and even do not know exactly how much was made last month and how much is currently in stock.

At present, inventory management system is in manual management of material import and export account book according to ISO9001. There are 500 books in the account book, but there are only 300 in the real warehouse. to be.

Due to the lack of materials management solution development compared to HR and accounting programs, the management cost burden of small and medium-sized construction companies and manufacturers is continuously increasing, and the invisible loss cost of companies is increasing due to inefficient management of various materials. In addition, due to the lack of proper management measures, the formal management of material management is being carried out, and it is impossible to grasp real-time status information about the loss and damage of materials occurring during the day due to the security system of the security company.

By adopting RFID technology, it is possible to easily manage materials in distant material warehouses in the construction company's office, and eliminate the difference between inventory on accounting book and existing inventory, and can be managed efficiently in connection with accounting system.

You can see the status information such as theft, loss, damage, stock status in real time, and you can efficiently manage the materials on the site.

It is expected to spread to all industries such as automation of expensive materials management of construction companies, simple management of manufacturers, and inventory management of distributors. Existing system was possible only with complex and professional accounting and asset management knowledge, but it can spread asset management to all the small and medium companies. Currently, the management of expensive equipment and materials is performed manually by attaching RFID chips to manage the entire system from introduction to inventory status and shipping, especially the real-time inventory defects and damages through video cameras. This is possible.

The realistic and efficient RFID-based yard management system aims at a standardization system that can flexibly respond to the expansion of items and businesses, and establishes an environment so that all relevant information such as basic information and history information can be managed in the field. The principle that the existing infrastructure can be recycled is to utilize the existing resources as much as possible, and the system is constructed with the highest priority on the stability and scalability of the system in consideration of the future expansion stage. The system also complies with international standards for RFID technology.

RFID-based yard management system manages information up to the history and registration information of the yard managed in the field; The site manager requests the service provider to use the service, and registers the producer information and the related history information by the corresponding history products based on the system user ID. Management of information up to registration of distribution history of the cargo; The site manager applies the service to the support organization, and registers the collection-related information on the property by the historical goods received from the producer based on the user ID. Receive a history label (RFID or barcode) along with the history number and attach it to the yard. Middleware for building integrated environment; It processes the data sent from RFID Reader and transmits only the information needed by the user and stores it in the database. CCTV; In order to manage the material of the yard or the warehouse, CCTV is installed and the image information is transmitted to the manager in real time to prepare for the risk of theft and damage. User interface; The UI is configured to be easy to use by the administrator, and the inventory quantity and incoming and outgoing status are implemented as a web interface that can be checked in real time. A portable handheld terminal; In order to manage or check the goods in the field and the warehouse while using the handheld handheld terminal to search for materials and goods, and transmit them to the management server to help the efficient management of materials and goods.
