In order to reduce costs,simplify the hardware design about remote monitoring system and increase system's stability,based on AVR Atmega series of MCU(Micro Computer United) Flash code structure of the district,the reading and writing RWW(Read-While-Write),non-reading and writing at the same time(NRWW:Not Read-While-Write),boot loader,the application areas are studied.The development of the download page guide treatment,examples program(the direction of the net topology map about the management system of student's using electricity),and code conversion are improved.The main purpose of the research is reducing costs,simplifying the hardware design about remote monitoring system and increasing system's stability.The practice has proved that the applications of the resource code's long-range rewriting about the single-chip of AVR Atmega series,remove a series of the complex external circuit that can achieve remote upgrade in the past.
