通信電源監控系統下位機硬件電路的設計

摘要：通信電源集中監控系統作為電信網運行維護的重要支撐手段，將發揮越來越重要的作用。本文在分析現有監控系統不足的基礎上，提出了一套本地用通信電源監控系統方案，并對其下位機部分的硬件電路設計進行了詳細的論述。經實際使用表明：采用了文章提出的硬件電路設計方案的這套通信電源監控系統具有精度高、成本低、易升級等優點，對于目前已相當普遍的本地用通信電源系統十分適用。 敘詞：通信電源；監控系統；下位機；多微處理器 Abstract：Severed as the necessary supporting of telecommunication net, the centralized supervision and control system for power supply is becoming more and more important. Based on the analysis of shortness in present supervision and control systems, a set of project for supervision and control system for local telecommunication power supply is presented. This paper also discusses the hardware circuit design of the supervision module for telecommunication power supply supervision and control system in detail. The results of practical use shows that the provided design scheme of this system has the advantages of high precision, low costs, high expandability, etc, thus is adaptable for the increasingly common local telecommunication power supply.
