RFID technology allows test paper management to create higher security and confidentiality

近年来,随着多元化发展of examination categories and the trend of informatization of examination scales, the safety of examination papers has been highly concerned. The safety and confidentiality of test papers is a very important task in exam management. RFID radio frequency identification technology test paper management has greatly reduced some of the safety risks in the process of inventory, storage and transportation of test papers, so that the information collection in various links can be well documented. Greatly save manpower, material resources, financial resources and time, while also improving work efficiency, allowing managers to provide accurate, comprehensive and fast decision-making reference.

RFID is the specific application and development of automatic device 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, so that people can automatically identify and manage various objects or devices in different states.

RFID technology test paper tracking management, establish a safe and efficient management information. Ensure the information security of test papers and provide a fair platform for candidates. RFID technology affixes an electronic label and reads the collection information on the test paper bag or test paper box, and collects the data of the test paper through the RFID tag for transmission. After the test paper is completed, it will go through several processes such as printing, transportation, storage of each test management structure or test center, use of test center, storage, transportation, examination and archiving. By setting up a sensing terminal at each link, the dynamic information collection of the test paper bag is realized. The monitoring system model of test paper circulation is mainly composed of 3 parts: wireless sensor network, data transmission network and monitoring center.

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

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

Exam management remote monitoring center is composed of remote monitoring personnel, database server, WEB server and multiple terminal devices. Through accurate analysis of the data transmitted from each monitoring terminal and monitoring node, the real-time monitoring and testing of test papers in the entire circulation process is realized. Early warning processing.

For a test paper bag, what is ultimately determined is a specific and exact examination room information, which is achieved by encoding the information, and at the same time, a one-to-one correspondence with the radio frequency tag information. Through this correspondence, not only can the position of the test paper bag be determined, but also the content of the test paper bag can be located. Figure 1 shows a specific and detailed flow chart for a certain type of examination.

RFID-based test paper management research can achieve real-time monitoring of test papers in the process of circulation, thereby truly ensuring the safety and confidentiality of test papers. RFID technology is used 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 candidates.
