Research on single-phase smart meter
Abstract:The structure and properties of watt-hour meter need to be continuously improved and perfected with the development of power industry and the continuous improvement of the power management system. The single phase intelligent electric meter designed in this paper is mainly composed of the microprocessor AT89S52 chip CS5460A watt-hour meter, display circuit, storage circuit, keyboard circuit and front-end signal processing circuit. Processed by the front-end signal, grid signal is sent to CS5460A for switch and calculation. Then the calculation result is transmitted to MCU AT89S52 which controls the display of OCMJ4X8CM and stores the result with X5045 as a core. In addition, you can use the keyboard module to materialize client-side control function. The simulation results show that the intelligent meter’s design scheme is feasible with a reasonable circuit module design, higher accurate measuring, and standard technical indicators meet the requirements which can satisfy the basic needs of users.
