摘　　要：为了满足新的国家电网公司企业标准对远程集中抄表系统集中器的规范要求,提高集中器的整体性能,设计和实现了一种采用工业级微处理器AT91SAM9G45和嵌入式Linux操作系统的远程集中抄表系统集中器,完成了集中器的硬件电路理论设计、功能仿真和电路实验,并开发出了相应的控制软件。实际运行的实验结果表明,该集中器的整体性能良好,能满足新的国家电网公司企业标准对集中器的规范要求,并且其软件系统还具有开发进程短,高可扩展性和高可移植性特点,具有广阔的应用前景。State grid corporation of China put forward the new enterprise standards of the concentrator in remote concentrated ammeter reading system. To meet these new standards and improve the overall performance of the concentrator, a design of the concentrator based on AT91SAM9G45 MCU and the embedded Linux operating system is proposed and implemented. Theoretical design of the concentrator hardware circuit, functional simulation and circuit experiment are completed, at the same time, the control software of the concentrator is developed. The actual running experiments show that the overall performance of the concentrator is improved, and the concentrator meets the new standards, moreover, its software system has the characteristics of shortening the development process time, high scalability and high portability. It will be widely used in the future.
