Abstract
With the increasing demand for electricity, the problem of power shortage is becoming more and more serious, which greatly restricts the development of social economy. In order to save electric energy and make rational and efficient use of electric energy, it is necessary to measure electric parameters accurately and in real time. This requires electronic technology support.
Electronic technology is based on the principles of electronics, using electronic components to design and manufacture a specific function of the circuit to solve practical problems of science, including information electronics technology and power electronics technology. Information electronics technology includes analog electronics technology and digital electronics technology. Electronic technology is the technology of processing electronic signals. The main ways of processing are signal generation, amplification, filtering and conversion.
In this paper, the principle of electric parameter measurement is discussed, and the single chip computer technology is used to replace a large number of hardware in traditional instruments with software. The maximum power frequency voltage is displayed digitally. Its accuracy and convenience are greatly improved. On this basis, the software and hardware development process of the whole system is introduced in detail. Finally, the error analysis of the system is carried out.
