摘要
通用串行键盘(即USB键盘)是心电图测试仪最易受静电干扰的部分,基于这个问题,首先介绍了静电和USB的传输原理,其次,从物理结构和电路设计出发,总结可能存在的问题,最后,针对问题提出一系列对策措施,提高心电图测试仪的静电防护能力。
Universal Serial Bus keyboard is the electrostatic-sensitive part of Electrocardiograph. Based on the problem, First of all, the principle of electrostatic and the principle of USB transfer are introduced. Second, the summary of possible problems from the physical structure and circuit design, Finally, a series of countermeasures to improve to solve the program.
