Configuração de sistemas de controle industriais baseada em dispositivos móveis sem fio.

Abstract

Nowadays, wireless communication is considered as one more available resource to aid in the automation and process control. The development and implementation of wireless network infrastructures in industrial environments are increasing gradually, however all the potentiality of the wireless technology still needs to be explored. Furthermore, there is a continuous and increasing demand in the industry for configuration and management tools to control industrial processes that provide significative reduction of time in configuration and programming activities of control systems, as well as flexibility, portability, reliability and easiness. In this context, a remote configuration tool for industrial control systems using wireless technology can be developed to satisfy these required characteristics. Therefore, in this work, a remote configurator of control algorithms to industrial control applications, compatible with a system with wireless connectivity, capable of performing automatic code generation and which can be incorporated to the control application, is presented. The used architecture for the remote configuration system defines a client-server structure based on two entities, Base Station and Remote Station, communicating each other by a standard wireless technology. The client part (Remote Station) is used for graphical user interface and remote operation, consisting of a software running in a portable device (remote configurator) responsible for configuration of control algorithm using block diagram representation. The server part (Base Station) consists of a system capable of performing automatic code generation from block diagram models. In general, industrial applications in which sensors and actuators are used to control parameters and/or the state of the control system are favorable to implementation of the architecture of the remote configuration system, providing connectivity and integration in a simple and practical way with remote stations. Therefore, the remote configuration system proposed can be considered a potential application in the industry.
