基于AVR双CPU的太阳模拟器及其故障注入系统

Sun-simulator Based on Two AVR MCU's and Its Malfunction Immitting System

介绍基于单片机AVR设计的太阳模拟器及其故障注入系统的设计和在某卫星GNCC(制导、导航和控制计算机)分系统地面测试中的应用。提出通过TCP/IP协议,经网线注入故障数据的方法和解决方案。阐述AVR双CPU系统数据交互,协调工作的实现手段。本系统在GNCC室内联调的实际使用中,完成了预期的功能。

The paper presents the design of sun-simulator based on AVR MCU and its malfunction immitting system.The application in the ground-test of satellite GNCC-subsystem is also introduced.The solution of malfunction data immitting is brought forward that malfunction data is immitted through network line according to TCP/IP protocol.It expatiates the means of data exchanging and harmonious working of two AVR MCU＇s system.The equipment is used in the inside-room associated test of GNCC,and achieve the prospective functions and performance.
