1. An Infrared Array Sensor System: Basic Technology for Achieving Human-Centered Smart Buildings
Mitsuhiro Honda, Sei Nagashima, Shoichiro Aoyama
Azbil has begun selling an infrared array sensor system that consists of sensors developed for air conditioning control and a device that aggregates the data measured by the sensors. This novel product operates without the use of a room temperature sensor installed on a wall or a pillar. It provides comfort and energy efficiency using feedforward air-conditioning control based on a wide range of surface temperature measurements obtained by infrared array sensors. In addition, by detecting human and outputting its results, it is a basic product for achieving smart buildings. It can be applied to air conditioning, lighting control, ventilation control, etc. In this paper we report mainly on the technological aspects of the product.
2. Prediction of Cavitation Erosion in Control Valves Using Computational Fluid Dynamics
Kenji Saito, Chongho Youn
Erosion often occurs in control valves due to cavitation. Therefore, for valve manufacturers, the prevention of erosion and suppression of cavitation are important technological problems. As one attempt at a solution, we used an unsteady computational fluid dynamics (CFD) analysis that took cavitation into account, and visualized the results of analysis using published erosion indexes. As a result, we found effective indexes for locations of control valve cavitation erosion, and from the CFD analysis we were able to estimate the relationship between the forms of occurrence of erosion and cavitation.
3. Innovative Production Processes at Azbil’s Mother Factory
Koji Seki, Takashi Yano, Munekazu Katagiri
The acquisition of advanced production technology for the creation of new products, the pursuit of continuous reduction in manufacturing costs, and the improvement of manufacturing quality are some of the roles of the “mother factory” that stands in the vanguard of azbil Group production. This paper describes advanced production processes utilizing sensor packaging technology acquired over many years, including the precision mounting and microassembly of parts using AI image processing technology and force-control technology. In addition, we report on our efforts to construct a globally deployable flexible manufacturing system that supports multi-product variable production and customized production in order to meet our customers’ various needs, as well as our efforts to eliminate human error and to construct a new flexible production line.
