摘要
根据应答器长期应用实践,按照EN50129进行隐患识别、风险分析和安全功能定级,发现应答器设备存在SIL4(Safety Integrity Level 4)级别的安全功能,给出对该SIL4安全功能的设计原则与测试方法。
Based on the authors＇ experience of balise application over a quite long period, we conduct hazard identification, risk analysis and allocation of safety function according to the specification of EN50129, and find that the balise has SIL4 safety function. Furthermore, we bring forward the principies of designing balise and the method to test the principles.
