The Electric Parameter Acquisition And Processing System That Based On Radio Communication

The data acquisition system has became the basic of modern measurement and control system, and has been widely used in obtain data in various field. Because of the convenience and agility of the radio communication technology, more and more data acquisition and processing system has take the advantage of radio communication, especially in long-distance data acquisition and processing system. Take the advantage of the data acquisition and processing system that based on radio communication in electric parameter acquisition can not only save manpower and material resources, but also has great meaning in power network automatization.Established in the electric parameter acquisition and processing system that using in the reactive power compensate device, the design mentioned in the paper uses alternating current acquisition achieved by AVR MCU to voltage and current signals in order to get all the parameters of the electric power, namely, voltage, electric current, frequency and reactive power. An easier method is used in phase angle acquisition, which can collect the frequency of the power network and phase angle and can also make sure of the direction of phase angle, can reduce the outer hardware sources and thus simplify the design. Voltage and current signals got by alternating current acquisition analyzes harmonious waves in power systems through FFT ( Fast...
