基于PSTN的可远程监控录音录时系统设计

Design Realization of Remote Monitoring Sound and Time Recording System Based PSTN

提出了一种基于PSTN(公用电话网)方式下的远程监控录音时系统的实现方法。该系统由1个远端监控端和若干个本地录音端组成,利用两路电话线,通过调制解调器拨号实现远程实时监听回放功能。经过实践验证达到了较好的效果。

A system arechitecture and implementation method of remote monitoring sound and time recording system, which is based on the Public Switched Telephone Network （PSTN） , are provided to meet the need of airline manipulation center for call recording supervision and control. This system is consisted of one remote monitoring point, many recording points and PSTN. Recording point is used to get sound wave information and recording. Remote monitoring point is used to complete various functions of the real-time remote monitoring and control by modem. The good effect has been achieved through the test.
