【摘要】：核电数字控制系统是核电站的重要组成部分，在核电站的长期、安全、稳定运行中起着举足轻重的作用。但是由于目前缺少成熟的测试工具，对核电数字控制系统进行可靠性测试验证非常困难。因此，针对核电数字控制系统可靠性测试问题，本文提出了一种基于软件故障注入的测试方法，，通过对核电数字控制系统现场控制站中各处理单元板卡进行故障设置，测试验证系统的可靠性。首先，本文分析研究了故障注入技术和故障注入测试工具的国内外现状，重点分析了故障注入原理，通过对故障注入技术进行分类研究，深入地比较了各类故障注入技术的优缺点。依据该技术发展现状，详细分析了它的应用领域。其次，针对核电数字控制系统的特点，给出了对其进行故障注入测试时采用的注入方法和触发方式，并提出了测试平台的总体设计方案。以核电数字控制系统现场控制站中通信单元CU(Communication Unit)板卡为例，详细分析了针对该处理单元板卡的故障注入测试场景。再次，在交叉开发环境下，以Workbench为开发平台，嵌入式C语言为开发工具，完成了故障注入测试工具——检测器的软件实现。实现过程中采用的自定义协议提高了测试工具数据传输的灵活性，功能库的封装避免了不必要的冗余代码。最后，以CU槽号故障为例，对其进行软件故障注入测试，验证了检测器功能的完备性和故障注入方法的可行性。
[Abstract]:Nuclear power digital control system is an important part of nuclear power plant, which plays an important role in the long-term, safe and stable operation of nuclear power plant. However, due to the lack of mature testing tools, it is very difficult to test and verify the reliability of nuclear power digital control system. Therefore, aiming at the reliability test of digital control system of nuclear power, a test method based on software fault injection is proposed in this paper, through the fault setting of each processing unit board card in the field control station of digital control system of nuclear power plant. First of all, this paper analyzes the current situation of fault injection technology and fault injection testing tools at home and abroad, focuses on the analysis of fault injection principle, through the classification of fault injection technology, The advantages and disadvantages of various fault injection techniques are compared in depth. According to the present situation of this technology, its application field is analyzed in detail. Secondly, according to the characteristics of nuclear power digital control system, the injection method and trigger mode used in fault injection test are given. The overall design scheme of the test platform is put forward. Taking the communication unit CUU Communication Unit card in the field control station of nuclear power digital control system as an example, the test scene of fault injection for the board card of the processing unit is analyzed in detail. Thirdly, in the cross-development environment, the Workbench is used as the development platform. The embedded C language is the development tool, and the software implementation of the fault injection testing tool-detector is completed. The custom protocol used in the implementation improves the flexibility of the data transmission of the test tool, and the encapsulation of the function library avoids unnecessary redundant code. Finally, taking the CU slot number fault as an example, the software fault injection test is carried out. The completeness of the detector function and the feasibility of the fault injection method are verified.
