INTRODUCTION With the development of radio frequency technology, product-related information can be quickly obtained by the readers if RF tags are assigned to each product. Recently, people have began to adopt IPV6 and even IPV9 protocol formats for RF tag coding since IPV4 address space has been used up. If the server storing product-related information is stored in an IPV4 or IPV6 network, how to query RF information across the network should be solved. This paper mainly studies the RF information query process of interconnection between decimal network and Internet network and the domain name conversion rules obtained by decimal network query server. II. IPV9 IPV9, short for decimal network and the new generation of Internet, is the result of China's independent innovation of core technologies which has IPV9 protocol, IPV9 addressing, digital domain name system and other core technologies are adopted with original and independent intellectual property rights. Full digital text is used to represent the IP address. The address space is larger than that of IPV4 or IPV6. The 1st-41th level of the address space is expressed as binary 256 bits, while using the decimal 256 bits to express the 42th. III. RFID Radio Frequency Identification(RFID) is a non- contact automatic recognition technology. It communicates with other object using reflected power. It can automatically identify target objects and obtain relevant data through radio frequency signals, which can quickly track items and exchange data. And also, the identify ability need no one to participate in. A typical RFID system consists of electronic tag, reader (including antenna) and application system. Further, electronic tags are the data carrier of RFID system which consists of a label antenna and a label chip. It can receive the reader's electromagnetic field modulation signal and return the response signal to achieve the label identification code and memory data read or write operations. The reader is used to receive host commands and send the data stored in the sensor back to the host by the wired or wireless way. It contains a controller and an antenna. If the reading distance is long, the antenna will stand alone. The terminal computer of the application system interacting with the RFID system transmits the work instructions issued by the MIS application system. It makes electronic tags and readers be coordination through middleware, processes all data collected by RFID system, and carries out calculation, storage and data transmission. The process can be described as Fig.1and Fig.2. Figure 1.

Electronic tags The operating principle of RFID system is to receive the radio frequency signal emitted by the reader when an item with an electronic tag enters the radiation range of the reader antenna. The passive tag sends data stored in the tag chip using the energy generated by the induced current, while active electronic tags can send data stored in the tag chip, actively. Generally, readers are equipped with middleware of certain functions. Hence, it can read data, decode and directly carry out simple data processing, then send to the application system. The application system judges the legitimacy of electronic tags according to the logic operation, and carries out corresponding processing and control for different Settings, thus realizing the basic functions of RFID system. IV. NETWORK ARCHITECTURE BASED ON IPV9 RFID INFORMATION QUERY TECHNOLOGY RFID information query technology can provide people with the function of inquiring information related to products through the RFID tag. The information related to RFID tags is stored on the information server and is generally maintained by the manufacturer of the product. In view of the actual use of the Internet, it is necessary to design a network architecture for interconnection between the decimal network and the Internet, which meets certain conditions. On this basis, RFID tag information query service is implemented. The overall network architecture design scheme is as follows. A. Overall design of network architecture The architecture of RFID tag information query service on Internet is based on IPV4 and IPV6 protocols. Routing adopts IPV4 and IPV6 protocols, and resource positioning is completed by SNS and PSNS. The architecture of electronic tag information location query service based on decimal network is a network architecture based on IPV9 protocol, including the following two ways. (1) Using the routing to locate the information server directly. The route uses the IPV9 protocol without the DNS resolver. (2) Adopting the parsing service of the application layer with U-code Resolution Server. DONS uses host domain name resolution to provide IPV4, IPV6 and IPV9 addresses, while using IPV4, IPV6 and IPV9 protocols as routing protocols .Resource positioning is done by D-ONS. The network architecture of RFID tag information query service mainly includes the decimal network information query service technology system and the Internet information query service technology system. Specifically, the decimal network architecture includes middleware, information server, D-ONS server, DDNS and IPV9 direct router. Internet architecture includes SNS server, PSNS server, information server, .cn root DNS server, DDNS server and.cn root. DNS server through the domain name resolution forwarding digital domain name and English domain name connectivity. B. The key module of network architecture -- expert module The expert module is the middleware used between the decimal network and the Internet to realize the interconnection between the two, and the data exchange format between the two is XML. It includes the following interfaces.  RF information query of Decimal network and architecture of discovery technology input product and service digital identifiers to query the Internet RF information, through the expert module, discovery technology architecture request to return the product and service specific information storage address or URI.  RF information query of Internet and architecture of discovery technology input product and service digital identifiers to query the Decimal network RF information, through the expert module, discovery technology architecture request to return the product and service specific information storage address or URI.  RF information query of Decimal network and architecture of discovery technology input product and service digital identifiers to query the Internet RF information, through the expert module, discovery technology architecture request to return the product and service specific information. International Journal of Advanced Network, Monitoring and Controls Volume 04, No.04, 2019 76  RF information query of Internet and architecture of discovery technology input product and service digital identifiers to query the Decimal network RF information, through the expert module, discovery technology architecture request to return the product and service specific information. V. RESEARCH ON INFORMATION QUERY PROCESS Based on the above network architecture, the implementation of RFID tag information query service based on IPV9 can be designed in two ways: D-ONS based decimal network and Internet network information query and direct routing mode of exchange visits between decimal network information query service system and Internet information query service system. A. Exchange query process Between D-ons-based decimal network and Internet network information query service system When the related product information is stored in the Internet information server and label coding format is using able format, the decimal network based on D- ONS accessing the information query process of Internet mainly involves the following several key modules: decimal network query server, decimal network, expert module, information server middleware, the SNS and PSNS server. The access relationship between these modules is shown in figure 3.

International Journal of Advanced Network, Monitoring and Controls Volume 04, No.04, 2019 77 h) PSNS returns the NAPTR record containing the product and service information service or PSDS address. i) The service middleware returns the results to the expert module, whose decimal network interface returns service of the product and information or NAPTR records of PSDS address to the query server. j) Querying the server request and finally getting the product information returned by the information server. When product-related information is stored in the information server of the decimal network, and the label encoding format is IPV4 or IPV6 format, the D- ONS based decimal network needs to be accessed through the Internet network. The access process involves the key modules: Internet query server, expert module, D-ons server, information server. The access process is shown in figure 4. decimal network D-ONS resolve server D-ONS server Information server Domain resolve server Expert modul label reader Requery server a) b) c) f) d) e) g) tandard id code and domain name onversion Network distributed query control product and service domain name Address of information server identifiers of product and service. identifiers of product and service.

It involve the query server, expert module, middleware, information server, SNS server and PSNS server. International Journal of Advanced Network, Monitoring and Controls Volume 04, No.04, 2019 78 The interconnection of IPV4, IPV6 and IPV9 can realize the mutual visits between IPV4, IPV6 and IPV9 through protocol conversion. Specifically, a protocol conversion server needs to be set up, and all data packets are converted into specified protocols to satisfy the data communication between different protocols.
