  Due to the continuously increasing demand for more comfortable residential or commercial buildings in the last decades the researches in the so called “intelligent buildings” topic has emerged as one of the most challenging and high ranked engineering task. Consumers also require a higher level of security, supervision, and control of the buildings according to a large scale of user needs. These expectations face building automation and supervising system developers with a challenging problem, difficult to approach with classical methods or strategies. Therefore, this paper is focused to outline novel facilities and solutions offered by the current level microelectronic technologies in building automation. In the first step of this endeavor the benefits and advantages of the reconfigurable hardware systems is highlighted and outlined. Then a concrete building automation and supervising system implementation in hardware reconfigurable technology is presented and detailed. The main unit of this system has been built upon a Genesys Virtex-5 FPGA-based development board, as a high speed, parallel, and distributed computing reconfigurable unit. The software modules for building supervising and monitoring purposes embed last generation MicroBlaze technology which allows fast and convenient implementation of sophisticated control algorithms. The result of the entire development is a powerful and versatile system representing a well suitable solution for the most sophisticated and demanding customer needs in building supervising and monitoring applications.

  At product manufacturing the time-to-market factor, the profitability and the delivered value define the success of an enterprise. The increasing number of modules in Enterprise Resource Planning (ERP) programs is a facing problem, when there is a margin between the manufacturing cells and the ERP. Nowadays, the connection between the industrial machines and the ERP is an important requirement especially at automated warehouses and smart factories. Other concerns at manufacturing are the maintenance schedules of the machines, and flexible and easy reconfiguration of the production lines or the production cells. Information technology provides solutions and software environments to implement complex production supervisor ERPs at smart factories. At a production line or an automated warehouse several technical parameters and information can influence the planning of the resources at the enterprise, like maintenance, machine error, stockpile, product ID, defective product ratios, etc. When there is machine maintenance, the company needs to order the service parts, as well as schedule the service time and the stop of the production line. In case of a machine error, the system can estimate the length of the service time from error messages, and reorganize orders, transportation, or even maintenance schedules of other machines. Our plug and play type robot and industrial automation controller project gives a solution for these hardware demanding needs.

  Due to advanced technology, it is very important the performance of FMS for sensivity, production quality, repeatability and energy consumptions. Flexible manufacturing systems (FMSs) are the most automated and technologically sophisticated of the machine cell types used to implement cellular manufacturing. An FMS usually has multiple automated stations and is capable of variable routings among stations, while its flexibility allows it to operate as a mixed model system. The FMS concept integrates many of the advanced technologies that we met in previous units, including flexible automation, CNC machines, distributed computer control, and automated material handling and storage.

  In this experimental investigation, vibration and accelerations analysis of an experimental FMS with 5 degrees of freedom robot manipulator are presented. Firstly, experimental measurement of accelerations and vibrations are trained with a vibration measurement system and sensors. However, the process of production of part is a cycle of exact production time.
