摘要
以电梯内外呼为研究对象,论述了电快速瞬变脉冲群(EFT)干扰的原理和诱发显示故障机制;提出了一种结合电梯内外呼板卡硬件和软件逻辑控制策略的系统性解决方案,能够解决电快速瞬变脉冲群干扰防护问题。结合典型实例,并对比前后测试效果验证了本方案的有效性。
Taking elevator external calls and car calls as the research object, the principle of fast transient current pulse group(EFT) interference and the mechanism of induced display failure are discussed. A systematic solution combining hardware and software logic control strategy of elevator external calls and car call board are proposed, which can solve the problem of electrical fast transient pulse group interference protection. Taking a typical example, the effectiveness of the scheme is verified by comparing the test results before and after.
