指控系统网络设备在时间、空间上的信息协调量大,结构组成复杂,综合保障难度大[1];文中从维修保障的角度,针对指控系统网络设备接口类型多、智能化程度高和测试层次分明、故障定位要求精度高等特点,研究了性能测试指标和故障诊断测试方法,开发了基于ARM的测试系统;系统提出了一种模拟组网测试技术,构建虚拟网络环境,形成测试回路,实现对网络设备的离线测试;对于目前复杂的指控系统网络设备测试诊断具有重要现实指导意义。
Accusing system network equipment in the time and space coordination of large amount of information, complex structure, comprehensive support difficult [1]; From the perspective of maintenance and security, for the accused system network equipment interface type, high degree of intelligence and test level The characteristics of the fault location requirements are clear, the performance test index and the fault diagnosis test method are researched, and the ARM-based test system is developed. The system presents a simulation networking test technology, builds a virtual network environment, forms a test loop, Offline testing of network equipment; for the current complex network testing equipment accused system has important practical significance.
