摘要
数字录音系统是进行核对和事故追忆与分析的重要设备,目前,轨道交通数字录音系统普遍存在着录音信息不全或造价高昂的问题,在分析专用电话系统的组成及录音现状的基础上,提出了对专用电话系统的集中录音方案,介绍了集中录音的系统原理及特点,证明了集中录音能够满足专用电话系统对重要终端录音的需要。
The digital recording system is an important device for accident checking, recall and analysis. At present, the common situation of digital recording system in rail transportation has some problems such as incomplete recording information or high cost. Based on the analysis of the dedicated telephone system composition and the status quo of centralized recording solution, this paper proposes the centralized recording solution for dedicated telephone system, introduces the system principle and features of centralized recording system and proves that the centralized recording can satisfy the requirements of the key terminal recording in dedicated telephone system.
