Abstract : Aiming at remote data collection and control of excitation system of small hydropower generator , a new type of built in single
chip ATMEL90S8535 is adopted in the design of small hydropower generator excitation system remote measuring and control device , and it
finds application in hydropower plant in mountain areas. The design and realization of remote control cell cored by built in single chip AVR
are introduced , and the high efficiency programming method in C language for this type of single chip is also presented.
Key words : small hydropower ; single chip AVR ; remote data collection and control ; C language
