[Abstract]:With the determination of the national smart grid development strategy, the smart meter, which is the cornerstone of its construction, has also got a large space for development, and the State Grid Company according to its own needs. A series of technical specifications and technical standards have been formulated and issued in line with China's national conditions. At present, intelligent ammeters are developing rapidly and are gradually replacing the traditional mechanical ammeters and ordinary electronic ammeters, compared with the traditional ammeters. The intelligent electric meter has high measuring precision, complete function, stable performance, automatic monitoring and repairing function of the system at the same time. This paper designs a three-phase remote fee control intelligent watt-hour meter, referring to the functional requirements and design specifications of the three-phase intelligent meter. In addition to the metering function, it also has the functions of electric information collection, two-way communication, remote cost control, power loss monitoring, anti-theft, load switch control and so on. First, this paper introduces the background of intelligent watt-hour meter. At present, the development status of intelligent watt-hour meter at home and abroad is introduced, and the main function and technical index of three-phase remote fee-controlled intelligent watt-hour meter design are introduced in detail. Then, the overall hardware design of intelligent meter is introduced emphatically. Based on the ADE7858 three-phase meter metering chip of ADI Company and the MCU LPC1766 based on ARM Cortex-M3 kernel, the modular design technology is adopted. The power module, measurement module, microcontroller module RS485 communication module, infrared communication module are introduced in detail. Function and working principle of the key circuits such as load control module. From the point of view of software engineering, the software divides the watt-hour meter software into several functional independent modules by using the object-oriented modular design idea. Each module independently develops, has the unified format and the specification; The module uses a unified interface to facilitate access and call, each module function can be configured according to specific needs, the whole software design is easy to develop and maintain. Finally, the system debugging of intelligent watt-hour meter is introduced. The accuracy, electrical performance, insulation performance, electromagnetic compatibility and software function of the watt-hour meter are tested and verified in detail. Through the test report issued by the China Institute of Electric Power Science, it can be concluded that the three-phase remote fee control intelligent watt-hour meter designed in this paper is reliable in performance and strong in anti-jamming ability. The accurate measurement of the watt-hour meter fully meets the requirements of the State Grid Company for the three-phase remote fee-controlled intelligent watt-hour meter, and has a broad application prospect. Finally, the future development of the intelligent meter is prospected. The continuous development of communication mode will promote the intelligent ammeter to be more intelligent, networked, multifunctional and human-computer interaction.
