Measurement and Control Systems Measurement and Control Systems for Future Infrastructure Development IMURA Kazuhisa Trends in Measurement and Control Systems and Toshiba's Approach MIMURA Akihiro / HARA Hideyuki / KUSAKABE Hiroyuki Measurement and control systems are widely used in various fields including industrial systems, public facilities, and other facilities. Demand has been growing in recent years for improvement of energy efficiency, enhancement of reliability and productivity, establishment of safer and more secure systems, and inheritance of plant operation technologies in such fields as building management systems, factory automation systems in steel plants, petrochemical plants, paper mills, and so on, as well as in the field of social infrastructure systems such as water and sewage monitoring and control systems. In response to this broad range of market needs, Toshiba has been developing major components of measurement and control systems incorporating the latest technologies. Functional Safety and Plant Data Management Solutions for Steel Plants SAKAMOTO Tadashi / YOSHIDA Akihiko / DOJO Koji Toshiba Mitsubishi-Electric Industrial Systems Corporation has launched its two latest control and monitoring technologies for steel plants. The first technology is the safety PLC, a safety programmable logic controller in the TMACSTM (Toshiba Mitsubishi-Electric Advanced Control Solutions) series. This provides a control system with functional safety in response to requirements for enhancing system safety if problems occur. The other technology is called the TM-PDS, comprising various plant data management solutions with scalability based on our steel plant database (uDB) such as remaining life assessment of mass induction-heating equipment. These solutions are realized by collecting and utilizing a variety of time-series data via the TC-netTM 100 and TC-netTM 1G control networks as well as product data. Realization of Advanced Plant Monitoring and Control System Focusing on Alarm Management NAKANO Hiroshi / SUGIMORI Hisayoshi / TATENO Genki In recent years, distributed control systems (DCSs) have been playing a leading role in manufacturing systems. From the standpoint of plant safety management, it is necessary to set up an appropriate alarm system and establish an alarm management system for the life cycle of the plant. With these trends as a background, TOSDICTM-CIE DS/nv, a DCS developed by Toshiba, supports a new alarm system that promptly informs operators of significant changes taking place in the plant through alarms on the display to assist them in making judgments and taking the necessary actions. Furthermore, TOSDICTM-CIE DS/nv not only offers monitoring and evaluation of the existing alarm system for highly efficient plant operations, but also supports redesign of the alarm system for alarm management throughout the plant's life cycle. Industrial Controllers Meeting Sophisticated User Requirements SHIBAMIYA Toru / HIROTA Tatsuo / SHIBATA Koji Industrial controllers are used in control systems in manufacturing facilities and environment-monitoring equipment in a variety of fields including general industry, social infrastructure systems, and electric power plants. In order to meet the growing demand in recent years for control systems offering greater safety through enhanced functional safety, environmental harmony by means of energy saving, and more efficient operation, there is an ongoing need for the application of the latest technologies as well as the effective utilization and inheritance of existing technologies for industrial controllers. To satisfy these increasingly sophisticated user requirements, Toshiba has been expanding its lineup of the Unified Controller nv seriesTM with further strengthened functions. Latest Industrial Computers Supporting Social Infrastructure Systems ANAN Kazuhiro / AZUMA Takao / IZAKI Kosuke Industrial computers are widely applied to social infrastructure systems including various types of monitoring and control systems. With the expansion of the scale of social infrastructure systems and the progress of networking and hierarchization of information in recent years, industrial computers are required to provide increasingly high processing performance as well as high reliability, robustness, and maintainability exceeding those of general PCs. Toshiba has developed the FR2100SS series industrial computers as its latest models in this field. Equipped with the third-generation Intel® CoreTM i7 processor, the FR2100SS series achieve the performance and functionality required to meet the demands of today's social infrastructure systems. These models offer not only high reliability, secured by the use of selected parts, shipment tests, and the application of our original redundant array of independent (inexpensive) disks (RAID) system, but also easy setting due to their 2U form factor and easy maintenance achieved by a design that allows components such as fans and hard disk drives (HDDs) to be replaced from the front. Furthermore, the stable operation of social infrastructure systems is sustained by long-term product support and the offer of compatible models. LQ520 Microwave Density Meter to Meet Requirements of Chinese Market WATANABE Kazuhiro / SAKATA Shinichiro / KIMURA Makoto The rising proportion of the Chinese population living in urban areas has led to the construction of sewage treatment plants to accommodate the increasing amounts of sewage and sludge. In Japan and various other countries, the concentrations of sewage and sludge are generally measured continuously using microwave density meters in the sewage treatment process at sewage treatment plants and in the pulp and paper, food, and other industries, to achieve stabilization of both optimal chemical dosing and the concentration of dehydrated sludge. In China, on the other hand, sewage treatment plants employ intermittent concentration measurement without the use of microwave density meters. Hence, in order to reduce the processing cost per unit amount of sewage and sludge in China, it is necessary to accelerate the dissemination of microwave density meters there. In response to this situation, Toshiba has developed the LQ520, a new type of microwave density meter with appropriate performance and functionality for the Chinese market. We achieved reductions in the size, weight, and cost of the LQ520 by reducing the detector weight and the number of circuit boards. TOSGAGETM-C2710BPS·A Width Gauge System with Hole Detection Function Applying High-Speed Cameras for Steel Rolling Lines TAKEMURA Shota / NAKAO Tsutomu / KAJIWARA Tatsuya Rolling line measuring instruments are widely used to measure the thickness, width, shape, and surface defects of the product at all stages of production in steel rolling mills, from upstream processes such as the hot rolling line to downstream processes such as the surface inspection line. Toshiba has been developing and supplying these instruments for a broad range of applications utilizing its proprietary radiation detection and optical sensing technologies. In the field of optical measuring instruments, measuring accuracy and detection resolution depend on the performance of the optical sensor employed in the instrument. We have now developed the TOSGAGETM-C2710BPS·A, a new width gauge system with a hole detection function that realizes hole detection at higher resolution compared with conventional instruments. This has been achieved both by the use of high-speed cameras compliant with the CoaXPress high-speed image data transmission standard mainly for machine vision applications, and improvement of the image processing performance. Moreover, lower power consumption and reduction of environmentally harmful substances have also been realized. |
