摘　　要：在电子设备调试和故障诊断过程中,往往需要通过外部接口模拟器对电子设备的接口和通信链路问题进行辅助判断。讨论的接口模拟器主要负责对电子设备接口的监控和测试,所测试的接口形式主要包括千兆以太网接口、专用串行外设接口(SPI)、光纤接口、RS422差分接口、低压差分信号(LVDS)/晶体管-晶体管逻辑(TTL)。接口模拟器的主要功能包括接入被测电子设备对接口进行测试检查、串联接入被测试电子设备对接口进行监控、模拟环境监测数据收集功能、分别接收若干传感器的环境数据。In the process of electronic equipment debugging and fault diagnosis,the external interface simulator is often necessary to perform the auxiliary judgment on the faults of electronic equipment interface and communication link.The interface simulator discussed in this article is primarily responsible for monitoring and testing the electronic equipment interface,the tested interface forms mainly include Gigabit ethernet interface,special serial peripheral interface (SPI),fiber interface,RS422 difference interface,low voltage differential signal (LVDS)/transistor-transistor logic (TTL) interface.The main functions of interface simulator include:switching in the device under test to test the interface,switching in the device under test in tandem to monitor the interface,simulating environmental monitoring data collection function,respectively receiving the environmental data of a number of sensors.
