| 中文摘要:为了提高智慧站场周界的安全性，提出了一种智慧站场周界入侵行为在线报警技术。利用光纤光栅振动传感技术，通过控制参数初始化，提取智慧站场周界入侵信号的特征，构建入侵概率矩阵，计算入侵行为的状态转移概率，建立入侵行为与观测攻击指令序列之间的关系。在检测到入侵行为的最佳状态时，系统发出周界入侵行为报警信号，实现智慧站场周界入侵行为的在线报警。实验结果表明，该技术能够有效发出报警信号，并将漏报率和误报率控制在10%以内。 |

| Abstract:In order to improve the security of the smart station perimeter, a smart station perimeter intrusion online alarm technology is proposed. By utilizing fiber Bragg grating vibration sensing technology and controlling parameter initialization, the characteristics of the intrusion signal around the smart station are extracted, an intrusion probability matrix is constructed, the state transition probability of the intrusion behavior is calculated, and the relationship between the intrusion behavior and the observation of the attack instruction sequence is established. When the optimal state of intrusion behavior is detected, the system sends a perimeter intrusion behavior alarm signal to achieve online alarm of intelligent station perimeter intrusion behavior. The experimental results show that this technology can effectively send out alarm signals and control the missed and false alarm rates within 10%. |
