【Abstract】 Aiming at the problem that the common performance monitoring method for engine is not applicable under high power microwave environment,a novel performance monitoring system combining field-wire with electromagnetic pulse protection and passive optical network access technology is proposed. An electromagnetic simulation model of monitoring node coupling response is built,and the electromagnetic protection performance of CAN( Controller Area Network) bus diagnosis node under typical high power microwave environment is analyzed quantitatively. The test results indicate that the proposed performance monitoring system has strong electromagnetic pulse immunity under broadband high power microwave with a peak field intensity of 50 k V/m,monitoring data and control command have been transmitted between test area and monitoring area in a real time.更多还原
