【摘要】 介绍了一种基于SoC FPGA的光伏电力通信管理机系统的设计方法。该系统采用新型的集成有ARM硬核处理器的SoC FPGA作为主控芯片,将传统通信管理机的运算和通信工作进行合理划分,并由FPGA和ARM处理器协同实现。通过采用软硬件相结合的设计方式,本系统能够简化电路设计,降低通信事务对CPU的中断数量,增加支持MODBUS协议的RS485端口总量,并通过独立的NIOS Ⅱ备用系统保证了系统在灾难情况下的可恢复性等,所以更加适合光伏电力系统中多设备、大数据量的应用。更多还原

【Abstract】 A design method of photovoltaic power communication management system based on SoC FPGA is introduced in this pa-per. The system uses the new-type SoC FPGA integrated with ARM hardcore process as its main control chip, which divides the work of operation and communication of traditional communication management unit reasonably and is implemented by FPGA and ARM processor. By adopting the design of combining hardware with software, this system can simplify the circuit design, reduce the number of CPU interrupts for communication transactions, increase the total number of RS485 ports which support MODBUS proto-col, and the system is recoverable in a disaster situation through the independent NIOS Ⅱ backup system, etc, so it is more suit-able for the application of multiple devices and massive data in photovoltaic power system.更多还原
