Smart meter introduction

The continuous development of microelectronic technology and computer technology has caused a fundamental change in the instrument structure. Microcomputer (single-chip microcomputer) is the main body, and computer technology and detection technology are organically combined to form a new generation of "intelligent instrumentation", which is automated in the measurement process. Compared with the conventional measurement circuits of traditional instruments, measurement data processing and functional diversification have made great progress. The intelligent instrument can not only solve the problems that the traditional instrument is difficult or impossible to solve, but also simplify the instrument circuit, improve the reliability of the instrument, and achieve the purpose of high precision, high performance and multifunction. With the further development of science and technology, the intelligence of instruments will become higher and higher. The intelligent instrument not only can accurately display a variety of physical quantities, but also can provide various functions such as transmission output, relay control output, communication, and data retention. Smart meters and smart sensors are generally used in fieldbus systems. These instruments and sensors are embedded with communication modules and control modules that can perform data acquisition, data processing and data communication functions. It is said that ordinary instruments and sensors are used. Added a microcontroller.
