【摘要】 本文总结了直流屏智能监控的现状和发展趋势。通过对漏电检测多种方法的优缺点的分析，提出了注入直流信号进行漏电检测的方法。通过对蓄电池的特性的分析，利用悬浮地技术研制出蓄电池自动巡检系统。结合直流屏系统充放电控制中存在的问题，研究提出三级自动监控直流屏方案，给出了直流绝缘、参数监控、蓄电池监控，主监控、数据通信等电路设计和程序流程图。在此基础上，考虑到系统在工作环境的可靠性，对系统的电磁抗干扰问题做出一些分析，并提出了一些措施。更多还原

【Abstract】 The paper sums up the intelligent monitoring actuality and trend of the DC panel .By analyzing many method’s advantage and disadvantage of the leaking electricity inspection, the paper brings forward a method of the leaking electricity inspection by injecting the direct current signal. To analyze characteristics of the accumulator, the perambulatory inspection system of the accumulator is studied and made by using the suspended ground. The project of the three-step automatic system monitored direct current panel is put forward after thinking of existent questions in which the direct current panel charged and discharged the accumulator. The circuit design and software flowchart about direct insulation, parameter monitoring system, accumulator monitoring system, main monitoring system, communication etc are presented. After them, on account of the reliability of its working circumstance , the electromagnetic immunity of the system is analyzed a little and some methods have given up.更多还原
