ADuC812及其在海底光缆的绝缘在线监测系统中的应用

ADUC812 and its application in on-line supervision system of insulation status of the submarine optical fiber cable using ADuC812

为了及时监测到海底光缆绝缘故障,避免发生光缆断路故障,本文设计了一种基于AD公司的新型数据采集芯片ADuC812的海底光缆绝缘在线监测系统。该系统能及时发现故障并告警,有效地消除了海底光缆的安全隐患。文中对该系统测量绝缘电阻的原理、工作方式、主要功能和硬件结构作了详细说明。最后将该系统测得的数据和传统仪器所测得的数据进行分析比较,实验结果表明,该系统的精度比较高,完全符合工程使用的需要。

As the first phenomenon of many faults of the submarine optical fiber cable is insulation fault, we design an on-line supervision system using ADuC812, which is a new type of micro converter of AD, to supervise the insulation status of the submarine optical fiber cable and capture faults in time. It can find faults, alarm and eliminate hidden trouble of the submarine optical fiber cable. The report also introduces the principle, function, and structure of the system. By analyzing the data, we can conclude the resistance measured by this system is much more precise than that measured by old instrument.
