Abstract:

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.
