Modeling and numerical simulation method for systems with distributed parameters

The present work introduces and uses the concept of “Partial differential matrix of state vector Mdpx”, associated to Taylor series, for modeling and numerical simulation in Cartesian space of the processes with distributed parameters. The case study presents a control system and shows the important steps, the advantages, the disadvantages and the precautions which are imposed by utilization of the proposed method.

Self organizing bluetooth networks for the packaging industry

The process automation in the packaging industry requires an increasing number of intelligent devices like sensors and actors. These must communicate with the main programmable logic controller (PLC) and exchange settings and process data. Conventional techniques offer the possibility to realize this communication using wired devices. In industrial automation, fixed wired devices have the disadvantage to provide an inflexible automation network on the field level, so that a new concept to realize the communication was required. This report describes the alternative to realize a self organizing wireless network using the Bluetooth technology and the evaluation of the concept through a prototype. The prototype bases on a DC motor, typically used in packaging machines to change the batch specific mechanical settings. This motor was equipped with a Bluetooth module that allows an easy, time-reduced adjustment of the new settings.

A monitoring system for contaminated pharmaceutical processes

The automation of contaminated processes in the pharmaceutical industry is a crucial point of interest for manufacturers. The areas where the active pharmaceutical ingredients are penetrated the entire production room must be secured very careful, to avoid any healthy damage of the employees. Examples for dangerous ingredients in high concentration are insulin and antiplatelet agents (blood thinner). These can be easily absorbed in high concentrations through the human skin. The contaminated persons suffer heavy healthy damages or can even decease. To avoid accidents, the manufacturers have introduced independent systems for process control, video and audio surveillance. This paper describes the alternative to realize a compact monitoring system that unifies all the systems listed above. The concepts uses as hardware industrial web cameras, a wireless table personal computer (PC), a WAGO 750-841 controller from WAGO GmbH [1] and a special designed monitoring PC. The software was developed using Microsoft Visual Studio 5 [2] and VisiWin 6.0 from Inosoft GmbH [3].
