摘要
针对传统传感器技术在火灾探测中存在的不足和目前基于CCD火灾图像探测的缺陷,利用火灾图像特殊性以及图像识别和处理技术,采用高性能的DSP+FPGA硬件系统结构和GPRS无线传输技术,设计了火灾图像探测系统,并对所设计的系统进行了试验分析。结果表明,该火灾报警系统具有误报率低、价格便宜、响应快、监控范围广等优点。
Aiming at the shortcoming of the traditional sensor technique in the fire detection and the current defects of fire CCD image detection, using the specific characteristies of fire image, image recognition and processing technology, a new fire image detection system based on structure of DSP and FGGA hardware system and GPRS wireless transmission technology was designed. The experimental analysis of the system were given. The results showed that the system had many advantages, such as low false alarm rate, cheaper price, fast response, and wide range of monitoring.
