Cellular Phone Control Application as an Undergraduate Research ProjectAs technology advances, items like the cell phone have become an integral part of people’severyday lives. Finding new innovative ways to incorporate devices like cellphones into our livescan help improve both productivity and efficiency, and can help reduce the cost associated withthe purchase of other, more expensive technologies. Creating a smart phone application that canremotely control motor speed is a demonstration of the capabilities of wireless technology thatcould lead to many other similar applications of this technology. This undergraduate researchproject uses smart phone technology as a control device by demonstrating that it can be used tocontrol the rotational speed of a DC motor. Specifically, this project will involve thedevelopment of a fast and real time method to control a device that is readily available to thepublic and relatively easy and inexpensive to implement in industry.A smart phone application will be created using a graphical user interface (GUI) that representsthe controls of a motor and a display of the requested motor speed. The brand of smart phonemust accept custom programmed applications. The smart phone will be programmed to interpretGUI inputs and create wireless signals. The hardware used to create and transmit the wirelesssignals will be pre-existing in the phone and common to most phones available in the market.An embedded control system will receive the wireless signals from the smart phone and interpretthose signals as a desired motor output speed. Separate intelligent hardware devices will likelybe needed, one for receiving and translating the wireless signal into a commonly usednetworking language, and a second device used to interpret the control signals and drive themotor. The motor speed will be varied by a pulse width modulated signal generated in the seconddevice that will likely require a transistor to switch the high currents required to spin the motor.Creating a control system that interacts with signals generated with common devices can haveseveral uses throughout industry. This work can extend to all areas of automated measurement,instrumentation, and controls. One potential outcome is the elimination of the need forexpensive human-machine interfaces (HMIs) at the monitored equipment, thereby significantlyreducing overall equipment costs.The benefits and limitations of incorporating this effort into an undergraduate engineering orengineering technology curriculum will then be explored. Among the issues to be addressed arethe technical (hardware and software) capabilities required of both the students and faculty toenable cell phone technology to be employed in control and communication systems courses.
