摘要
分析了数字化消防系统的特点,针对消防现场的特殊需求,主要解决了红外图像的压缩算法和红外视频编码方案设计;采用自顶向下的设计方法,建立了符合ISO分层标准的网络层次模型,给出了系统关键部分的数据流图;设计了无线通信的主动和被动两种通信模式,以克服恶劣工作环境的限制;重点阐述了CPLD+DSP方式的硬件系统,简要介绍了系统的软件结构.
The features of digital fire protection systems are analyzed. To fit the special requirements of digital fire protection systems, the image coding and infrared video coding are mainly provided for a spot fire protection system. According to the Top-down principle, a network model based on the ISO standard is established and its primary top level data flow is given. Both the active and passive communication modes are designed to overcome the limitation by the bad environment. The CPLDTDSP hardware framework and software framework are also discussed.
