结合我国火灾报警系统发展现状,提出了基于Internet的火灾报警信息系统,针对常规路由器公平转发所有数据包,提出了一种能识别对实时性不同要求的数据包,并能智能插队转发对实时性要求较高的数据包的新的调度算法,可减少路由器转发对实时性要求较高的数据包的延迟时间,提高在Internet上传输紧急信息的时效,为低成本实现对实时性要求较高的系统提供了一种新的思路.

According to the reality of the development of fire alarm system in our country, this paper offers a fire alarm information system based on Internet. Being different with the way of normal router in transmitting all data packages fairly, a new dispatch algorithm is put forward, which can identify different data packages of demanding different real-time performance and transmit the data packages of demanding high real-time performance by jumping queue intelligently. That decreases warning time delay and improves the dependability of important data transmitted by router. A new kind of method is proposed to satisfy a high real-time system at a low cost.
