Optimal Design of Intelligent Control System in the Communication Room Based on Artificial Intelligence

With the current data-driven era, there is the potential to employ controllers that can store a large amount of data, which is not achievable with traditional controllers. Our goal is to propose an intelligent controller system for computer room management based on artificial intelligence that maintains data integrity, saves memory, minimizes computation, and simplifies program design. To upgrade the computer room management system’s intelligence that is not high, the management mode that is not flexible, and the distributed large-scale management of the whole school that is difficult to realize, the original system is improved to the distributed computer room management system based on artificial intelligence. By starting from the actual situation of higher vocational college computer room, combined with the characteristics of the school computer room, we designed framework model based on distributed artificial intelligence machine room management system, the system by means of network communication technology and database access technology, put forward the B/S combined with C/S structure to realize the computer room management system model, and used radio frequency identification technology to develop radio frequency card. The results show that the optimization results of the traditional computer automatic control system in the computer room vary greatly and fluctuate between 0.6 and 0.8, while the control results of the automatic control system in this paper keep stable at 0.8, which can reach the ideal state in a short time. Through the outcome, it can be said that the proposed control method can be used of higher level of automation, flexibility, and robustness which will work effectively. Therefore, the improved system integrates software, hardware, communication, and distributed system technology into one, which greatly improves the control effect of computer automatic control process, and control result of computer automatic control process is more stable and has a certain practical application value.

Intelligent Library System Based on RFID Technology

Radio Frequency Identification (RFID) is a kind of automatic identification technology. It uses radio frequency to communicate two-way non-contact data, and uses radio frequency to read and write recording media (electronic tags or radio frequency cards) so as to achieve identification objectives and data transfer. It is considered as one of the most promising information technologies in the 21st century. In the field of Library management, it can improve the overall efficiency of libraries and reduce the cost of library management of mass books. In this way, libraries can put more funds and manpower into improving the quality of Library services.

DDAS-DRoF Based a New In-Building Signal Coverage System Supporting Multiple Services

Aiming at the problems of low infrastructure utilization rate, high cost, large power consumption, inconvenient management and maintenance caused by independent in-building signal coverage systems of different operators, this paper puts forward a new in-building signal coverage system supporting multiple services based on digital distributed antenna system (DDAS) and digital radio over fiber (DRoF). The proposed system will not only support existing 2G, 3G and 4G mobile communication services, but also be able to provide access and coverage for future 5G and applications such as the internet of things (IOT) and in-building positioning. Radio frequency (RF) unit and digital signal processing (DSP) unit are designed independently to reduce the correlation and constraints between RF part and DSP part so as to facilitate increase or decrease supported service, dynamic capacity expansion and smooth upgrade. Each service corresponds to a kind of RF card and all RF cards share the same DSP platform. Test results of laboratory, simulation base station and actual mobile network show that proposed system is able to support designed services and performance indexes meet the specified requirements of 3GPP and mobile operators well. This may provide a good platform for co-construction and sharing, saving capital expenditure (CAPEX) and operating expenditure (OPEX) and reducing energy consumption of in-building signal coverage system. It also complies with the development trend of multi-network integration and internet plus.

A Study on Analysis of Key Success Factors of a Serious Game: In Case of "Anti-Aging Village"

This paper is a case study for serious game to derive key success factors by production process. So I selected an arcade serious game for the elderly named “Anti-aging Village” according to the strict criteria. This research method is so subjective and qualitative, so I complemented by using clinical trials and play test results and by interviewing twice a director of this game. After analyzing a serious game I found some key success factors as follows; first, they had understood enough the state of growing elderly population in South Korea and designed gameplay well for improving cognitive function for the elderly. Second, they organized a development team including some experts and made use of the feature as a RF (Radio Frequency) card. Third, they validated the effectiveness of a serious game through clinical trials and play test. This paper will help for serious game design and could be the guideline for the development of serious game for elderly.

Functional evaluation of the Los Angeles smart card field operational test

This paper summarizes the functional evaluation of an Advanced Fare Payment System deployed in Los Angeles in the summer of 1994. The functional evaluation is part of a larger Field Operational Test evaluation (Chira-Chavala, T., and Coifman, B., 1996. Impacts of Smart Cards on Transit Operators: Evaluation of I–110 Corridor Smart Card Demonstration Project. UCB-ITS-PRR-96-17, Institute of Transportation Studies, California PATH Research Report, University of California, Berkeley, CA; Guliano, G. and Moore II, J. E. 1996. Evaluation of the I-110 Corridor Smart Card Demonstration Project. UCB-ITS-PRR-96-20, Institute of Transportation Studies, California PATH Research Report, University of California, Berkeley, CA) managed by the Partnership for Advanced Transit and Highways (PATH) for the California Department of Transportation (Caltrans) and the Federal Transit Administration (FTA). The demonstration project fielded two types of advanced fare cards incorporating very different technologies on three separate transit properties as part of a relatively low cost system constructed from components manufactured to commercial rather than industrial specifications. Overall, the system performed well. Radio Frequency (RF) Cards demonstrated extremely high reliability. Smart Cards performed less well then the RF Cards, but both systems greatly surpassed the standards for magnetic stripe cards. ©
