中文摘要：

核心部门使用的基于物联网的高性能计算机，需要在电磁干扰下，特别是在抗高功率微波作用环境下仍能正常工作。从抗高功率微波的需求出发，从信号滤波设计、信号光电转换设计和板卡设计着手，详细介绍了通信计算机关键电路设计，包括物联网层次结构、高功率微波工作原理、部分光电转换设计、电源的滤波设计以及微波实验。通信计算机通过供电输入设计、自研主板等关键板卡设计，包含直流滤波功能、功率变换电路和无联网关键部件的设计，实现了抗微波辐射的电路及结构模块。基于物联网高性能计算机需要经过多种测试来验证其设计的有效性，经过多种抗微波辐射试验测试，物联网高性能计算机通过了试验，实验结果验证了设计的有效性和可靠性。

英文摘要：

The high performance computer based on Internet of Things which the key department uses can work normally in electomagnet- ic disturbing, especially the HPM disturbing. Based on the needs of anti-HPM application, combined with design of signal filter, fiber transimission and circuit board, the main circuit design of mainboard and key component in the communication computer has been presen- ted,including Internet of Things hierarchy,high power microwave working principle,parts of the fiber-electric conversion design,design of power filter,and anti-HPM experiment. Communication computer consists of power supply input and the self-researched main board including DC filter,power exchange circuit,main components of IoT, which realize the circuit and the structure module of the anti-HPM. Verification tests based on the Intemet of Things anti-HPM computer design have been conducted to prove availability of the computer. The experimental results show that the design is effective and reliable.
