本文主要介绍一种新研制的数字量磁芯存储、模拟量电容保持的多路全电子数-模转换系统的工作原理。它和常见的步进电机系统相比,除了具有体积小、重量轻、耗电少、造价低,速度快、故障率低等优点外,同样也能在掉电及计算机或本系统出现故障时保护信息和被控系统的安全。当人工手调与计算机控制互相切换时可避免扰动。本系统还具有一个故障检测系统,以监视各部分的工作,以便能及时发现故障并作应急处理。
This article mainly introduces a newly developed digital magnetic core storage, analog multi-channel capacitor to maintain the whole electronic digital-analog conversion system works. Compared with the common stepper motor system, it has the advantages of small size, light weight, low power consumption, low cost, high speed and low failure rate. In addition, when the power is cut off and the computer or the system fails Protect information and accused of system security. Aural disturbances can be avoided when manual adjustments and computer controls switch between each other. The system also has a fault detection system to monitor the various parts of the work in order to timely detection of failure and emergency response.
