摘　　要：实际仿真软件网络连接错误故障检测过程中,受到噪声网络数据的影响,导致现有方法产生虚警次数过大。针对上述问题,提出一种嵌入式软件网络连接错误故障实时检测仿真方法。根据不同网络节点的数据应答间隙,计算嵌入式软件网络错误的响应特征和错误故障的发生周期,控制外部网络噪声数据的影响,将软件连接网络的若干个点作为保护单元,根据采样门限系数的重心,设定实时检测方式,模拟检测仿真的不变时间量,设定检测仿真窗口,最终完成实时检测仿真过程。实验结果表明,所设计的检测仿真方法发现故障能力较强,检测有效率较高,虚警次数较少,具有较好的效果。During the process of network connection fault detection, the noise interference leads to too many false alarms in traditional methods. Therefore, this paper proposed a real-time fault detection and simulation method of embedded software network connection error. Firstly, the response characteristics of embedded software network errors and the occurrence cycle of errors were calculated via the data response gaps of different network nodes. Secondly, based on controlling the external network noise data, several points of the software connection network were set as the protection unit, and then according to the center of gravity of the sampling threshold coefficient, the real-time detection mode was set to simulate the constant time amount of detection simulation. Finally, the detection simulation window was set to complete the real-time detection simulation process. The results show that the detection simulation method has sensitive fault detection ability, high detection efficiency, and low false alarm times.
