摘要
针对传统图像型火灾探测系统以PC作为处理终端,且不能对CCD摄像机进行有效控制等缺点,提出了以TMS320DM642为平台开发基于DSP/BIOS的大空间网络型火灾探测系统。该系统在DSP/BIOS与RF5参考框架的基础上,利用TCP/IP协议栈设计了多任务线程的应用程序,实现了火灾检测算法的移植与网络开发环境的构建。最终将视频处理结果由以太网传至控制中心,同时控制中心可以利用串口通信线程对CCD摄像机进行参数设置。
The traditional image-based fire detection system uses PC as processing terminal and can＇t control the CCD camera effectively.To solve these problems,the design of large space network-based fire detection system based on DSP/BIOS on the TMS320DM642 platform is proposed.The system uses TCP / IP protocol stack to design multitasking thread application based on DSP/BIOS and RF5,realizes the transplant of fire detection algorithm and the creation of the network development environment.Video processing results can be transmitted to the control center through the Ethernet,and the control center is able to use the serial communication thread to set the parameters of the CCD camera.
