通信电源集中监控系统作为电信网运行维护的重要支撑手段,将发挥越来越重要的作用。本文在分析现有监控系统不足的基础上,提出了一套本地用通信电源监控系统方案,并对其下位机部分的硬件电路设计进行了详细的论述。经实际使用表明:采用本文提出的硬件电路设计方案的通信电源监控系统具有精度高、成本低、易升级等优点,对于目前已相当普遍的本地用通信电源系统十分适用。 Communication power centralized monitoring system as an important support for the operation and maintenance of telecommunications network, will play an increasingly important role. Based on the analysis of the shortcomings of the existing monitoring system, this paper presents a set of local communication power monitoring system scheme, and its lower computer part of the hardware circuit design in detail discussed. The actual use indicates that the communication power monitoring system adopting the hardware circuit design scheme proposed in this paper has the advantages of high precision, low cost and easy upgrade. It is very suitable for the local communication power system which is quite common at present.
