摘要
为解决军事作战过程中由于外界环境复杂及强电磁脉冲武器而引起的显示器可靠性低、显示图像不稳定等问题,提出一种采用先天加固并用光纤传输替代电气传输的液晶显示器设计方案。以"模块化设计"思想为指导,详细介绍显示器的电路框架、硬件设计和软件设计,最后对整机的显示性能及环境适应性进行实验测试。结果表明在不同信号源输入下,显示性能良好;应力筛选实验及电磁兼容性实验都满足实验大纲的要求。验证了设计方案的可行性与实用性。
To solve the problems of low reliability and instability of the display in the process of military operations due to the complexity of the external environment and the strong electromagnetic pulse weapons,a design scheme of LCD which uses congenital reinforcement and optical fiber transmission instead of electrical transmission is proposed. Based on the idea of"modular design",this paper introduces the circuit framework,hardware design and software design in detail. Finally,the performance and environmental adaptability of the whole machine are tested. The results show that the display performance is good in different input signal sources,and the stress screening and electromagnetic compatibility tests are met the requirements of the test outline.The feasibility and practicality of the design scheme are verified.
