Devices that use radio transmitters and receivers frequency (RF) are used in various industries or business in Brazil, intended for communication or property security. The demonstration of magnetic fields and interference of radio waves, cellular mobile and other agents studied in this project result in disturbances and impacts on receiving signals that produces instability in RF devices and especially when your application is required and aims to provide security. Seeks to accomplish with this project development (feasibility study), assembly and testing of a device for controlling an electric hoist driven by frequency inverter using the technique of sending and receiving signals via radio frequency (RF). As a method of study developed a prototype that was installed and tested on a hoist industry to supply data via radio frequency (RF) and they offer security and stability to the equipment. The results showed that the controller via radio frequency (RF) - driven hoist on a frequency inverter is an excellent conductor signal producing stability in the signal transmission. In conclusion, it was pointed out studies on RF and constructed prototypes can be applied in a usual system, but can also be applied to solutions where control via absence of cables is required, for offering loyalty signs of arrival and departure.
