某型制导弹弹载计算机测试系统设计

Design on Test System of Guided-Missile-Borne Computer

弹载计算机作为整个导弹控制系统的核心部件,有着最复杂的电气功能及对外接口。以某新型号制导弹弹载计算机测试方法为研究对象,Lab Windows/CVI为开发平台,通过自主编程,设计并实现了一套弹载计算机测试系统。使用串口服务器实现了多串口同时控制,在CVI环境中应用基于多线程的异步定时器实现了多个高精度时钟。该系统具有功能较强、构建简易、定时器精度高、具有一定通用性等特点。某型制导弹弹载计算机的验收测试结果表明该系统能够完成具有复杂电气功能的弹载计算机测试任务。

The missile - borne computer, as the core component of the control system of missile, has the most complex electric functions and external interfaces. The test method of the missile - borne computer of a new guided missile is provided for studying, a missile - borne computer test system is designed and implemented by programming based on Lab Windows/CVI development platform. The serial port server is applied to control multiple serial ports simultaneously, asynchronous timer based on multithreading is applied to achieve several high precision timers in CVI environment. The system has such features as powerful function, simple structure, high precision timer and certain versatility. The test results of the guided- missile -borne computer show that the system can accomplish the test task of missile - borne computer with complex electric functions.
