Estudo da aplicação de rede sem fio em chão de fábrica

Abstract

The use of wireless technology has been growing and has reached the manufacturing industry. However, there is still a certain level of resistance towards its use, due to reliability. Some companies have already manufactured products which use wireless communication, and believe this technology will be used for communication between control systems, sensors and units within networks, due to its speed of instalation and alteration of layout. For this, the IEEE has created some standard technologies, such as wi-fi, Bluetooth and zigbee, which are being used by the industry. One of the questions raised by the practical use of wireless networks in factories is interference which can occur due to the large quantity of heavy equipment and the production of electromagnetic interference. In this research, some tests using conventional wireless networks with twisted pairs were carried out in various environments. The tests compared the difference in time of communication for the networks where the equipment was in an environment containing industrial equipment with that where it was in an isolated environment.
