摘　　要：为解决"电子线路实验(一)"课程所使用数字实验台核心板极易被高压静电击穿烧毁,导致学生实验失败的问题,该文在不改变现有数字实验台基础板的前提下,通过分析实验过程中静电放电现象的特点,采用"瞬态二极管并联+多通道复用"的设计方法,研究设计新型的核心板ESD防护电路。在严格控制成本、电路板体积的同时,该ESD防护电路可以增强数字实验台的抗击穿性,提高学生实验的成功率。In order to solve the problem that the core board of the digital experimental platform used in the "Electronic circuit experiment(I)" course is easily destroyed by high voltage electrostatic breakdown, which leads to the failure of students’ experiment, this paper studies and designs a new type of ESD(electro-static discharge) protection circuit for the core board by analyzing the characteristics of ESD phenomenon in the process of experiment and adopting the design method of "Transient diode parallel connection + multichannel multiplexing" without changing the existing core board of the digital experimental platform. While strictly controlling the cost and the volume of the circuit board, the ESD protection circuit can enhance the resistance of the digital experimental platform and improve the success rate of the students’ experiment.
