  • In this paper, we have designed the management System to monitor and control computers running on MS Windows in the PC room using SNMP. The proposed system has controlling capability to control the status of PC and monitoring functions to have real-time monitoring and process control. In the controlling system, it supports update and setting of the configuration information of PC and backup/restore the information when it happens to be some faults. In the monitoring system, it has monitoring the PC of students, controlling the process on PC, and invoking a new job. This system contributes to enhance the effectiveness of teacher's educational activities in PC room by controlling and monitoring the program running on student's computer.

  • Many various researches about the PC execution process monitoring system have studied. Nevertheless, it is hard to find research of a system that multi-PC based each PC can be monitoring and reporting by file type. In this study, it designed and implemented that each PC can be monitoring and reporting by files to a server in multi-PCs' environments. Moreover it can gather and organize informations of reporting. It is expected users can recognize that execution processes are reporting. It causes to reduce execution unnecessary process.

  • Mobile computers can process large amounts of data at high speeds, and it is feasible and easy to implement a remote monitoring system utilizing mobile computers. Because of their portability and convenience, these computers have been employed in various research areas to develop such monitoring systems. Existing monitoring system is a bit difficult to real time monitoring the scattered offshore facilities. So this paper compensate the existing system by using mobile computers such as a tablet PC-based monitoring system. Also, the scattered offshore facilities can be monitored in real-time through the tablet PC. The developed monitoring system is a fully Internet-based monitoring platform that enables one to monitor and control remote oceanic applications at any time and any place where it is possible to access the Internet. It can be applied to many oceanic applications as well as the unmanned systems and remote monitoring systems on land.

  • In order to make best use of NC machine tools with minimal labor costs, they need to be in operation 24 hours a day without being attended by human operators except for setup and tool changes. Thus, unattended machining is becoming a dream of every modern machine shop. However, without a proper mechanism for real-time monitoring of the machining processes, unattended machine could lead to a disaster. Investigated in this paper are ways to using PC camera as a real-time monitoring system for unattended NC milling operations. This study defined five machining states READY, NORMAL MACHINING, ABNORMAL MACHINING, COLLISION and END-OF-MACHINING and modeled them with DEVS (discrete event system) formalism. An image change detection algorithm has been developed to detect the table movements and a flame and smoke detection algorithm to detect unstable cutting process. Spindle on/off and cutting status could be successfully detected from the sound signals. Initial experimentation shows that the PC camera could be used as a reliable monitoring system for unattended NC machining.

  • In this paper, we implemented the monitoring and control of geothermal heating and cooling system using mobile devices. The main idea of this system is to provide the convenience if the system can be controled in remote place with monitoring using the mobile devices like PDA. Basically, the system consists of the Server-Client structure divided into two parts, one is PDA and PC, the other is PC and PLC(Programmable Logic Controller). The PDA, which is equipped with Windows CE as as, monitors the status of the devices (motors and sensors, etc) attached to PLC and controls them. This does the system to be controled by the commands, which we assume to control, with wireless transmission between PC and PLC. The PDA parts are responsible for monitoring and control the devices connected to the PLC, and the PC part which equipped with the application is to provide the relation between PDA and PLC. The Ladder Program is used to control the sequences of the PLC..

  • In this paper, it is designed and implemented the management system to monitor and control PCs running on MS Windows or NT and define some MIBs using SNMP. The proposed system has controlling functions to control the status of PC and monitoring functions to have real-time monitoring and control processes. The controlling system supports update and setting of the configuration information of managed systems and backup/restore the information when it happens to be some faults. The monitoring system has some functions such as monitoring the processes of the PC, controlling the process on PC, and invoking a new job. This paper proposes a way of enhancing the performance of monitoring capabilities by screen partitioning and analysis techniques.

  • In this paper, we have designed and implemented that PC management system has the function of monitoring and controlling system management MIB defined for PC management using SNMP in PC room. System management MIB consists of monitoring MIB for system and processor information and controlling MIB for backup and restoration. For this, we have added new defined MIB variables to standard MIB and displayed system information, processor information, backup and restoration information of managed PC. And the structure between management system and managed system is shown and process of system information, processor information, backup and restoration of managed PC is illustrated. On real environmental, by monitoring window version, CPU type, system memory and virtual memory and performing backup and restoration of managed PC, actual operation is tested. Management system gathers system information and processor information from managed system and performs backup and restoration for recovering fault of managed system. Hence PC managers can operate and manage many PCs on LAN, efficiently.

  • When a PC is infected with a malicious code, it communicates with the control and command (C&C) server and, by the attacker's instructions, spreads to the internal network and acquires information. The company focuses on preventing attacks from the outside in advance, but malicious codes aiming at APT attacks are infiltrated into the inside somehow. In order to prevent the spread of the damage, it is necessary to perform internal monitoring to detect a PC that is infected with malicious code and attempts to communicate with the C&C server. In this paper, a destination IP monitoring method is proposed in this paper using Bloom filter to quickly and effectively check whether the destination IP of many packets is in the blacklist.

  • At present, many machine leaning and data mining methods are used for analyzing and predicting structural response characteristics. However, the platform that combines big data analysis methods with online and offline analysis modules has not been used in actual projects. This work is dedicated to developing a multifunctional Hadoop-Spark big data platform for bridges to monitor and evaluate the serviceability based on structural health monitoring system. It realizes rapid processing, analysis and storage of collected health monitoring data. The platform contains offline computing and online analysis modules, using Hadoop-Spark environment. Hadoop provides the overall framework and storage subsystem for big data platform, while Spark is used for online computing. Finally, the big data Hadoop-Spark platform computational performance is verified through several actual analysis tasks. Experiments show the Hadoop-Spark big data platform has good fault tolerance, scalability and online analysis performance. It can meet the daily analysis requirements of 5s/time for one bridge and 40s/time for 100 bridges.
