基于ARM的火灾信息传输网关设计

针对城市消防远程监控系统中火灾自动报警系统的联网问题,提出一种利用Internet实现火灾自动报警系统与城市监控中心的联接方案,设计了系统的关键设备——基于ARM的嵌入式网关。设备中采用经过剪裁、内核版本2.6的linux系统,提高了信息处理和传输的实时性和可靠性,并在嵌入式操作系统的基础上,利用多线程及管道编程,实现了火灾探测信息的处理传输及上层监控中心和下层网关的信息交互。设备实际运行后的结果表明,该火灾信息传输网关能够顺利地对相关信息进行处理和转发,在广域网内实现了数据的实时、高速、可靠传输,满足基于互联网的城市消防远程监控系统要求。

Design of Fire Information Transmission Gateway Based on ARM

A linking scheme that connects the automatic fire alarm system with city fire monitoring center through Internet is brought forward to solve the networking problem of automatic fire alarm systems in city fire remote monitoring system.The system＇s key equipment called ARM-based embedded gateway was designed.The equipment ARM9 which transplants the kernel version 2.6 Linux operation system is adopted to improve the real-time performance and reliability of information processing and transmission.Based on the embedded operating system,the fire detection information transmission and exchange between upper control center and lower gateways are realized in combination with multi-threading and pipe programming.The actual running result of the equipment shows that the fire information transmission gateway can successfully process and transmit the relevant information,can achieve real-time,high-speed and reliable data transmission in the wide area network,and can meet the requirements of Internet-based urban fire remote monitoring system.
