摘　　要：针对某柴油发电机的模拟电子调速器进行改进,采用基于ATmega8作为处理核心的数字电位器转接板和速度设定板来与模拟电子部分进行交互,同时基于S3C2440 ARM9硬件平台和嵌入式操作系统Linux软件平台,运用串口通讯技术和Qt/Embedded,设计了一种具有综合功能的模数复合的调速控制系统。试验表明,该调速器能可靠地实现对柴油机发电机的调速控制、运行监控和数据管理三大功能。In this paper,an analog electronic speed governor for a diesel generator is improved into a multifunctional speed governor which can change data through digital-potentiometers board and speed-control board based on ATmega8.Also the governor is based on S3C2440 ARM9 and embedded operating system Linux,using the skill of the serial communication and Qt/Embedded.Experimental results show that the new governor can control speed,monitor the diesel generator and manage data effectively and reliable.
