During the Desert Shield Desert Storm operation, the US Army’s $2.7 billion spare parts were not used due to the lack of visibility of containers, resulting in significant economic losses. Therefore, resources were built and maintained in the process of equipment technical support. It is very important, which led to the development of the US military's joint asset-wide visualization and automatic identification technology.
Automatic identification technology is a tool for capturing, assembling, and transmitting data. It provides accurate and timely information about the status of materials, whether it is stored, shipped, or transported, thereby enhancing the system's ability to identify, track, and record. Control equipment, maintenance processes, power deployment/redistribution, equipment, personnel and material support capabilities are easily interfaced with other automated information systems with minimal human intervention.
The technology mainly includes technologies such as bar code, radio frequency data communication, optical storage card, radio frequency identification device, smart card, satellite tracking system and business processing server.
1) Barcode is the initial means of collecting and transmitting data. Currently, the main use of linear barcodes and two-dimensional barcodes and two-dimensional barcodes can provide single-piece items and document control information for carrying goods; two-dimensional barcodes can be documents, multi-item packages and Carrying assemblies provides comprehensive container data.
2) RF data communication enables the automatic identification technology device to interface with the automated information system it supports in real time.
3) Optical memory card consists of optical reading and writing and microcomputer. Data can be written multiple times in sequence, suitable for transferring large amounts of data during transport to facilitate data processing at the destination.
4) The radio frequency identification device consists of a radio frequency tag, a reader, a computer and a docking station. It is an all-round data collection and storage device that can be positioned or remotely visualized.
5) Smart cards are mainly used in systems that require small portable automatic identification devices, which can exchange data with automated systems. Combine smart cards with magnetic strips and barcodes to form an integrated system that improves performance, safety and accuracy.
6) The satellite tracking system provides near real-time tracking of the vehicle, equipment, fleet location and provides digital communication capabilities to the driver.
7) The business processor facilitates the automatic identification system to interface with the automated information system, automatically accepting information from the source of the automatic identification technology and converting it into the format required for the automated information system.
2 How automatic identification technology works
Attach bar code identification, RF card or label to boxes, pallets, vehicles or containers, automatic identification instruments such as barcode scanners, RF card readers, etc.) Collect and record goods and interface with other systems to provide initial source data , digitally stored in optical memory cards and radio frequency tags. The smart card stores the carrier's status data information, which is used to track the person after verification with the human data center database.
Radios are installed on the tracked vehicles and containers to read and transmit data. Through the RF data communication and satellite tracking system, the data information is transmitted to the automated information database update process, and the information is utilized to support other business processes. At the same time, the remotely extracted data in the automated information database is used on barcodes, optical storage cards, radio frequency cards or other automatic identification media. Figure 1 shows the collection and storage of transport visualization data using an RF automatic identification device.
Second, the application of automatic identification technology in the technical support of foreign military
Material storage supply
The US Department of Defense uses the automatic identification technology such as bar code, body frequency tag, and electronic memory card to visualize the storage assets, understand the quantity and status of assets in any place in the replenishment system, and improve the operational efficiency of the warehouse.
During the joint casting operation, the supply guarantee agencies in Hungary and Bosnia used optical storage cards to enhance the reception of multi-package containers. In the warehouse or distribution center, the optical storage card on the containers stores the materials contained in the multi-package containers. After the data arrives at the replenishment guarantee institution, it is scanned by the reader, and the data is input into the user's replenishment system: when the goods leave the important transportation center with the omnidirectional finder, the querier reads the label on it and transmits the data to A local area server where users can get data from the server.
2. Material transportation
The US military in operation "asset visualization system is one of the key parts to achieve full asset visualization." In normal, wartime and emergency situations, the system can transport goods, personnel, and air, sea, and ground transportation from the origin of transportation to the destination. Tracking the status, location, characteristics, etc. of assets: optical storage cards, barcodes, radio frequency tags and their readers, etc., to provide automatic identification technology for fast, accurate acquisition, retrieval and transmission of data, to identify the loaded goods and Location; in loading and unloading airports and ports, transportation centers and transportation hubs, and receiving units, the RF Finder automatically interrogates RF tags, which are transmitted to regional servers via satellite tracking technology and terrestrial lines, thereby providing visibility and improved visibility. Logistics logistics rapid response capability.
In the Korean theater, the US military conducted a test to track ammunition using radio frequency automatic identification technology. First, data is written from the database to the RF tag, a new type of RF tag that can be embedded in the wrinkled side of the container. Finder is installed in five places in Korea to track the RF from the unloading port to the ammunition warehouse and ammunition supply. Labeled containers that enable visibility of all types of supplies from the US to Korea;
3. Maintenance support
The automatic identification technology will greatly improve the efficiency of the maintenance of the weapon system and the informationization level of the maintenance. It is a multiplier to improve the maintenance capability of the US military. The automatic identification data collection/automatic identification technology developed by the US military contains a variety of information on the acquisition of information. "Data technology, can be queried in a variety of ways.
In order to obtain the latest information on important repair parts, the US Army's Supply and Rescue Agency entered the database using radio frequency finder and satellite tracking technology. The use of data provided by radio frequency technology enhances the spare parts replenishment and effective use of the troops and improves the level of readiness;
4. Other aspects
In terms of health care services, medical records of the wounded and sick can be stored in smart cards to enhance medical surveillance for the wounded and sick; smart cards can be used to identify military identity and other personal information.
Third, the development of automatic identification technology in China
The development and application of automatic identification technology in China is very rapid. Mainly used for toll stations, access control security systems, tracking vehicles and displaying traffic conditions.
