Automatiskt Nödstopp

Sammanfattning: In today’s industry it is starting to get more and more interesting with wireless systems and solutions for applications. To be able to reduce the amount of cables drawn to various machines which takes both space and an extra fee for every cable drawn. Some systems might require the user to use a handheld device that is directly connected by a cable which in some machines might be inelegant for the user. The goal with this bachelor thesis is to develop wireless monitoring of the machine operators position that is working with heavy industrial machinery. The thesis started out with researching different techniques for positioning a transmitter indoors, this was done in order to get a better understanding on how to go about. The technique that was chosen is positioning a transmitter by checking where the peak in signal strength is at its highest, this is done by rotating a parabolic reflector around the receiver’s antenna. The result is a solution to monitor the position of an operator at a rolling machine. The solutions function is to check at which angle the operator is currently positioned. By comparing this angle to the angles that is considered to be inside a dangerous zone, the system can determine if the operator is inside of that zone or not.
