基于IMS的气象信息传输智能语音通知系统设计与实现

Design and Implementation of an Intelligent Voice Notification System Based on IMS for Meteorological Information

目前气象信息传输监视工作主要依靠人工拨号辅助发送短信的方式将异常信息通知到台站,该方式的特点是对多个台站串行通知,及时性不足。介绍一种基于IMS的智能语音通知系统的设计与实现过程,包括系统硬件架构、软件系统设计。与基于语音板卡的方案相比,硬件架构以多媒体交换机为核心,以移动IMS为支撑,实现了TTS 4路并行转换、30路语音通道并发外呼;软件系统采用B/S和C/S相结合的方式来设计:C/S负责气象通信业务中异常信息的采集和语音通知的发送,B/S负责语音信息的显示、统计和分析。应用结果表明,该系统运行稳定可靠,体现了智能语音告警通知的优势。

The design and implementation process of an automatic voice alarm system based on IMS are introduced.The process consists of hardware and software architecture.Compared with the schemes based on voice cards,the hardware system is based on a multimedia switch and supported by IMS;therefore,it has the advantages of high stability,concurrency,and strong expansibility.The software system is built under C/S and B/S structures：the C/S part with high manageability and configurability collects exceptions appeared in the meteorological communication and sends corresponding voice alarm,while the B/S part is responsible for the display,statistics and analysis of alarm information.The application results show that the automatic voice alarm system is stable and reliable.
