An effective speed controller and GPRS based data acquisition system design for DC motors.

Parallel to the scientific and technological development, control over hardware used in industry and in daily life is being realized by using remote-controlled systems. Internet, mobile communications, and infrared and wireless control systems are often preferred. The control of a direct-current motor (DCM), which has become a part of our daily life, is achieved using a Pocket PC and General Packet Radio Service (GPRS). An Internet-based human-machine interface constitutes an embedded Visual Studio, which includes Windows CE 5.0 software and Smartphone and Pocket PC applications. An application server protocol is created using basic principles of GPRS control or communication system control. Client software is developed, real-time torque, speed, power, and current of a DCM are monitored, and motor speed control is performed using a monitoring system written in the C# language without using any additional equipment. The proposed system offers the possibility of real-time monitoring in a cost-effective manner.
