RFID technology escorts the confidential management of test papers

　　In recent years, with the diversified development of test categories and the informatization trend of test scales, the security of test papers has always been highly concerned. The security and confidentiality of test papers is a very important task of test management. RFID radio frequency identification technology test paper management greatly reduces some of the existing security risks in the process of test paper counting, storage and transportation, so that the collection of information in various links can be documented. It greatly saves manpower, material resources, financial resources and time, and at the same time improves work efficiency, allowing managers to provide accurate, comprehensive and fast decision-making reference.

　　RFID is the specific application and development of automatic identification technology in radio technology. This technology uses wireless radio frequency for non-contact two-way communication to achieve the purpose of identifying targets and exchanging data, and realize people's automatic identification and management of various objects or equipment in different states.

　　RFID technology test paper tracking management, to establish a safe and efficient management information. Ensure the security of test paper information and provide a fair candidate platform for candidates.

　　1. RFID technology attaches electronic tags to test paper bags or test paper boxes and reads the collected information, and collects and transmits the data of the test papers through the RFID tag.

　　2. After the test paper is completed, it will go through multiple processes such as printing, transportation, storage of each test management structure or test center, use of the test center, preservation, transportation, scoring and archiving.

　　3. The collection of dynamic information on the test paper bag is realized by setting a perception terminal in each link.

　　The monitoring system model of test paper circulation is mainly composed of 3 parts:

　　1) Wireless sensor network

　　In the entire test management test paper circulation monitoring system model, the wireless sensor monitoring network is the core of the entire test paper circulation monitoring system. It mainly realizes data collection through a variety of sensors, including the collection of test paper status data information, and the preliminary judgment of abnormal behavior in the test paper. It is collected by multiple detection nodes and transmitted to the information collection system in real time from the scanning terminal.

　　2) Data transmission network

　　The data transmission network must ensure excellent signal coverage and fast access capabilities, and ensure the real-time, security and stability of the data transmission monitored during the circulation of test papers.

　　3) Monitoring Center

　　The test management remote monitoring center is composed of remote monitoring personnel, database servers, WEB servers and multiple terminal devices. Through accurate analysis of the data transmitted from each monitoring terminal and monitoring node, real-time monitoring and Early warning processing.

　　For a test paper bag, what ultimately needs to be determined is a specific and exact test room information, which is realized by encoding the information, and at the same time achieving a one-to-one correspondence with the radio frequency tag information. Through this correspondence, not only the current position of the test paper bag can be determined, but also the content of the test paper bag can be located.

　　RFID-based test paper management research can achieve real-time monitoring of test papers in the circulation process, so as to truly ensure the security and confidentiality of test papers. The use of RFID technology to simplify the examination process and intelligent construction management, form a scientific and safe business process, improve the administrative efficiency of the examination, and create a safe and fair environment for the candidates.
