The link between it and the people's lives more to close with the power position in people's lives increasingly important. While the meter is constantly evolving, but limited to a single function, the conventional meters has failed to meet the growing demands of its users. In this paper, using the type microcontroller of STM32F103RC as the master chip, designed a practical, simple structure of multi-function meter. In the process of the design of meter in hardware and software, have adopted a modular design thinking. Among them, the hardware part of the multi-function meter includes control module, power conversion modules, voltage and current sampling module, EEPROM memory module, LCD segment display module, a key input module and RS485 communication interface module. And using software platform MDK designs the software part, including the main program, the system initialization procedure, power handler program, a keyboard interrupt program and LCD segment display program. Finally completed the system debugging of the multi-function meter, the voltage and current signals obtained through sampling and conditioning were calculated, and complete the display, but also through the select button to switch the display . The basic realization of the multi-function will be able to watch the intended function.
