Application of RFID technology in timber storage management in forest area

Generally speaking, forest areas are used as national timber warehouses, and the timber in the surrounding forest areas is classified and stored. From storage to storage, the staff will inspect and record the timber. The recording method has been greatly improved from the original paper report to the current bar code method. However, the limitations of barcodes also exist. For example: the barcode can only identify one type of product, but not a single product. Barcode is a visual communication technology, that is, the scanning device must “see” the barcode to read it. Its shortcomings, such as small storage capacity, easy damage and unrecognition, poor environmental adaptability, and inability to rewrite, expose some of its application drawbacks.
Unique advantages of RFID technology.It can scan quickly, identify and read severalRFIDLabels; small size, diverse shapes, not limited by size and shape, do not need to match the fixed size and printing quality of paper for reading accuracy, it has strong anti-pollution ability, and it is resistant to water, oil, chemicals and other substances Strong resistance. RFID tags store data in the chip, so they can be protected from defacement; they can be reused. Nowadays barcodes cannot be changed after they are printed. RFID tags can be repeatedly added, modified, and deleted. The data stored in the standard facilitates the update of information. RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and can carry out penetrating communication; the memory capacity of RFID data is large, and the maximum capacity is several MB , Which can meet the increasing demand for the amount of information that items need to carry in the future.
The application value of RFID technology in timber warehouse management:
The core of the RFID technology timber storage management system is to install a sensor on the truck where the timber is placed, and correspondingly install RFID readers at the passages of the warehouses. When the wood passes through the reader, the central computer can obtain wood information through the sensor on the wood truck. A certain number of RFID readers are also set up in the middle of each flute area in the warehouse and out of the warehouse to track the information of wood in the warehouse and out of the warehouse. In this way, the computer management center can realize the visual management of all business processes including automatic identification, positioning, transportation, storage and retrieval, and delivery of wood from the beginning of the storage.
(1) In the management of timber storage information, each piece of timber has a lot of information to be identified, such as tree species, timber type, timber length, material, diameter class, grade, specification, etc. All these information need to be manually managed in computer management. Entry, entry workload is large, not only has a long period, but also is prone to errors. Using RFID technology can solve these problems. Because of its large amount of information, it is especially suitable for the large-capacity requirements of timber storage information. In addition, its collection of information is automatic, not only the speed of collection is fast, but the error rate is particularly low.
(2) Traditional timber storage information is based on media such as paper and magnetic disks, and there may be errors in information circulation. With the development of information automation and network construction, the use of network for information transmission will become the main means of wood storage information circulation in the future due to its many advantages such as fast speed and low cost. Because the RFID system can be connected to the network, the information obtained by the radio frequency reader can also be transmitted on the network, which can ensure that the wood has an accurate flow of information during the circulation process, and can easily track the wood throughout the process manage. Therefore, using the RFID system to ensure the circulation of timber storage information is a more perfect solution.
(3) When a customer purchases wood of a specified species, it is difficult to find the location where it is located. It requires manual identification one by one, which is very inefficient and wastes a lot of time, manpower and material resources. Therefore, it is very necessary to carry out comprehensive positioning management of wood. This kind of management is achieved through automatic identification on RFID and a map marked with location information. For example, the map can accurately indicate the location of a wood subject to RFID management. The use of RFID technology increases the visibility of the location of the wood, and can easily find the target wood.
(4) After the application of RFID technology, since the wood entering and leaving the warehouse will be recognized by the reader, the data information collection efficiency is high and accurate. There is no need to manually enter the data, and there is no need to check the library, which can greatly improve work efficiency and Speed, reduce the work intensity of manual operation, and it is also a basic work for the implementation of management informationization.
