  • The rapid growth of algae occurs can induce the algae bloom when nutrients are supplied from anthropogenic sources such as fertilizer, animal waste or sewage in runoff the water currents or upwelling naturally. The algae blooms creates the human health problem in the environment as well as in the water resource managers including hypoxic dead zones and harmful toxins and pose challenges to water treatment systems. The algal blooms in the source water in water treatment systems affects the drinking water taste & odor while clogging or damaging filtration systems and putting a strain on the systems designed to remove algal toxins from the source water. This paper propose the emerging In-Situ self-diagnosable smart algae sensing device with wireless connectivity for smart remote monitoring and control. In this research, we developed the In-Site Algae diagnosable sensing device with wireless sensor network (WSN) connectivity with Optical Biological Sensor and environmental sensor to monitor the water treatment systems. The proposed system emulated in real-time on the water treatment plant and functional evaluation parameters are presented as part of the conceptual proof to the proposed research.

  • Ionizer is used in removal of static-electricity charge from several production processes such as flat panel display, organic EL, etc. In this paper, we introduce remote monitoring systems for ionizer which have been built to communicate with multiple ionizer and to control the power and ionizing state independently. Based on a series of tests, we verified the key functions of this controller such as unit connection, quantity of ion and electric charge, alarm, and successful communication between PC and controller. This system may be directly applicable to monitor systems for ionizer in the manufacturing processes of TFT-LCD, PDP, organic EL, and others.

  • This paper aims at developing remote control system to control and monitor distributed various devices through internet or information communication network. SNMP (Simple Network Management Protocol) and UPS (Uninterruptible Power Supply) are adopted for network management protocol and applied device, respectively. For controlling and monitoring distributed devices in real-time, Java-environment software is constructed. Also, general-use interface controller between network device and applied device is proposed. Finally, serial communication such as RS-232 and RS-485 is used between controller and applied device.

  • Recently, as safety accidents by reagents increase in laboratories, systems are being developed to safely manage reagents. The existing system monitoring and manages the reagent through the web page, but the internal environment change of the reagent cabinet is considered or the remote monitoring and control function is insufficient. In order to solve this problem, this paper predicts the deterioration of the reagent loaded in the reagent cabinet. And we propose a system that can monitoring and control remotely. It predicts the deterioration of the reagent through the temperature attached to the inside of the reagent cabinet, the value measured by the humidity sensor and the validity period of the reagent, and sends a alert message to the manager. The manager monitoring and controls the reagent cabinet through the application. By predicting the deterioration of the reagents and remotely managing the reagents cabinet it is thought that safety accidents can be reduced.

  • Communication Ocean Meteorological Satellite (COMS) for the hybrid mission of meteorological observation, ocean monitoring, and telecommunication service was launched onto Geostationary Earth Orbit on June 27, 2010 and it is currently under normal operation service on $128.2^{\circ}$ East of the geostationary orbit since April 2011. In order to perform the three missions, the COMS has 3 separate payloads, the meteorological imager (MI), the Geostationary Ocean Color Imager (GOCI), and the Ka-band antenna. The MI and GOCI perform the Earth observation mission of meteorological observation and ocean monitoring, respectively. For this Earth observation mission the COMS requires daily mission commands from the satellite control ground station and daily mission is affected by the satellite control activities. For this reason daily mission planning is required. The Earth observation mission operation of COMS is described in aspects of mission operation characteristics and mission planning for the normal operation services of meteorological observation and ocean monitoring. And the first one-year normal operation results after the In-Orbit-Test (IOT) are investigated through statistical approach to provide the achieved COMS normal operation status for the Earth observation mission.

  • This paper is for the on-line monitoring and controlling system in which remote central processor execute commands based on data transmitted via radio or cable captured from the industrial or marine environments. By executing the appropriate system commands, many mechanical parts in industrial environments and natural factors such as temperature and humidity are to be under control in the way of normal system condition. In this research, we control the temperature of a hydrochloric acid tank to be within the predetermined range by executing temperature controlling commands issued by remote central computer which decides the appropriate action for the total system based on the received sensor data transmitted via radio and cable media. This type of monitoring and controlling system has the various applications such as the disaster prevention system, ubiquitous embedded system, alarm system, and the USN systems.

  • In crowded subway stations indoor air quality (IAQ) is a key factor for ensuring the safety and health of passengers. Since physical variables that describing IAQ such as the concentration of particulate, $CO_2$, VOCs and biological agents need to be closely monitored and controlled in multiple locations within subway stations and in remote sites, concept of web-based monitoring and control network using both wireless and wired media needs to be implemented. Connecting remote wireless sensor network and device (LonWorks) networks to the IP network based on the concept of VDN can provide a powerful, integrated, distributed monitoring and control performance. In this study, performance of wireless and wired network in VDN for monitoring and control of IAQ in subway stations is evaluated. Specifically, delay induced in wireless and wired networks, and data transmission rate are evaluated. A key parameter is identified in assuring safety and health of passengers in subway stations.
