基于核电管道评估系统的硬件与故障诊断设计

以核电管道评估系统为对象,对其核心部分硬件系统的故障诊断与控制设计进行了研究。利用程控放大、幻象供电、故障诊断等电路设计了硬件调理模块。通过Keil软件对STM32芯片嵌入式软件编程的方式实现了硬件系统的控制与故障诊断功能,并由设计的串口通信协议经RS232与软件系统通讯。通过Labview软件开发了硬件自动化测试平台和故障诊断监测程序,保证硬件系统可靠性的同时提升了测试效率并减少了人力成本。设计的硬件控制与故障诊断模块满足要求,已成功应用在出口国外某核电厂的管道评估系统中,为核电厂安全经济可靠地运行提供了保障。

Design of Hardware and Fault Diagnosis Based on Nuclear Pipeline Evaluation System

Based on nuclear pipeline evaluation system, the fault diagnosis and control design of the core hardware system is studied. The hardware conditioning module is designed by means of program-controlled amplification, phantom power supply, fault diagnosis and other circuits. The hardware system control and fault diagnosis function are realized by Keil software programming STM32 chip embedded software, and use the designed serial communication protocol communicating with the software system through RS232. The hardware automatic test platform and fault diagnosis monitoring program are developed through Labview software to ensure system reliability, improve test efficiency and reduce labor cost. The designed hardware control and fault diagnosis module meets the requirements and has been successfully applied in the pipeline evaluation system of a certain nuclear power plant exported to other countries, providing guarantee for the safe, economical and reliable operation of the nuclear power plant.
