With the rapid development of the military Internet of things, not only the robot war, future use of various sensor technologies to build the IoT will form a real "ground network." Military Internet of Things refers to various military equipment through the military information sensing system and military information network connection to form a self-organizing military IOT network for military information exchange and communication, intelligent identification, positioning, monitoring, management and operations A network technology. In military IoT applications, radio frequency identification is one of the core technologies of the military Internet of Things. The radio frequency signal is used to read the data related to the target electronic tag so as to realize automatic identification, real-time tracking and management control, and has the advantages of waterproofing, Anti-magnetic, high temperature, long life, read a large distance, the label data can be encrypted, etc., the industry recognized as one of the most promising technologies of this century.
Military Internet of Things market broke out
In recent years, Internet of Things technology has been rapidly developed. The so-called Internet of things refers to a huge network of various information sensing devices, radio frequency identification technology (RFID), infrared sensing devices, global positioning systems and laser scanning devices connected to the Internet and thus Internet users The extension of things to achieve the exchange and interconnection of things and things, in short, is "Internet of Things (Internet of Things)." The Military Internet of Things is subordinate to the Internet of Things, but it links military elements such as things and things, people and things in the military field. Through the interconnection of the above networks, the real-time perception and rapid reaction to the battlefield situation can be realized. For example, the U.S. single-soldier information system can send and receive unified battlefield situation plans, fire plans and action plans, and can also access the tactical Internet To enable in-group broadcasts and peer-to-peer calls in specific areas. Through the use of this technology, all personnel and equipment of the entire Internet of Things have actually integrated into the joint operation system composed of the military Internet of Things, and the overall combat capability has also been significantly enhanced. Each military element that is based on the IoT system's combat operations, manpower, weaponry and equipment, and related materials is a network node with functions such as perceptual location, tracking and identification, image and video transmission, and intelligent management and control. Equipment can even be "spoken", take the initiative to report their own failures, can achieve self-diagnosis and communication of various equipment under field conditions, is an important means to achieve the best combination of information technology and manpower and equipment. The widespread use of the military Internet of Things has far more to do with the war: it can effectively enhance the ability of battlefield reconnaissance and surveillance to achieve the secret transmission of useful information; it can effectively shorten the command cycle and improve immediate combat capability; it can also improve logistical support Level, to ensure that the entire process of security visible, accurate and appropriate provision of equipment and supplies. In particular, the smart robot platform that integrates precision sensing devices has been praised as the "perfect substitute" for human soldiers and has broad application prospects.
As one of the core technologies of the Military Internet of Things, radio frequency identification technology is widely used in the military Internet of Things. What advantages does it have?
Speed ​​up information collection and improve management efficiency
Radio frequency identification originated in the aircraft during the Second World War radar detection technology. In 1948, "The use of reflected power communication" by Harry Stockman laid the theoretical foundation for radio frequency identification. According to the different frequency bands, the radio frequency identification system can be divided into four kinds: low frequency, high frequency, ultra high frequency and microwave frequency band. The low frequency and high frequency radio frequency identification systems have short working distance and low cost. The development has been very mature and mainly used in access control, Card and other fields. UHF and microwave band RFID system with read and write distance, anti-interference ability and other characteristics, in the warehouse management, transportation management, material tracking and other fields has been rapid development.
The core technology of radio frequency identification technology consists of electronic tags, readers and management platform and other components. Electronic tag is the identification information of the item, like the ID card is marked on the surface of the item for the reader to identify. Reader through the interface communication protocol and electronic tags for data exchange, pooling to the management platform for data acquisition, processing, integration, storage and utilization. In radio frequency identification, electronic tags attached to the article as long as access to the coverage area of ​​the reader, the reader can be obtained from the RF signal energy, automatically sent to the reader to send the product information stored in the chip. The reader receives the information of the electronic tag on the article and decodes it, and sends it to the management platform for data processing to automatically identify, register and process the article information and improve the level of information management.
