Research on Reactor Control Rod Position Indication Information Monitoring Technology Based on SOPC
-
摘要: 运用可编程片上系统(SOPC)技术,以现场可编程门阵列(FPGA)为数字平台,研究一种反应堆棒位信息监测技术。该监测技术将Nios II处理器、视频图形阵列(VGA)显示控制器、控制器局域网络(CAN)总线控制器等集成在一片FPGA芯片中,构建完成一个具有丰富功能的SOPC硬件平台。采用该硬件平台,可将棒位系统的运行状态信息实时、直观地进行数字化显示,同时以日志的形式存储在外部存储设备中,能够全方位地监测棒位系统的运行状态,使操纵人员能更方便、快捷地掌握整个棒位系统的运行情况。研制完成的原理样机验证了该技术的可行性。Abstract: A new monitoring technology for control rod position is developed by utilizing the FPGA（Field-Programmable Gate Array） platform and using the SOPC（System On Programmable Chip） technology.In this SOPC system,Nios II CPU,VGA（Video Graphics Array）display controller and CAN（Controller Area Network） bus controller are integrated in one FPGA chip.Thus the SOPC hardware platform with comprehensive functionality is constructed.Based on this SOPC platform,the real time data of control rod position indication system can be vividly displayed on the LCD and stored in the external nonvolatile RAM as history records.Therefore,the operator can obtain the overall operation status of control rod position indication system quickly and conveniently.The developed prototype has proved the feasibility of this technology.
