经过研究发现,火灾的发生机率具有双重性,即随机性与不确定性。而运用火灾自动报警系统检测火灾信号,就是将不确定的一面转化成比较准确的一面。基于此,利用BP神经网络算法计算和探测火灾图像的形成规律和信号特征,给出神经网络的具体结构和输入输出单元的设计方案。并对一系列的火灾样本图像和干扰图像进行实验。研究结果表明:此方法能更有效地减少火灾的误报警率,提高火灾报警的准确率。
經過研究髮現,火災的髮生機率具有雙重性,即隨機性與不確定性。而運用火災自動報警繫統檢測火災信號,就是將不確定的一麵轉化成比較準確的一麵。基于此,利用BP神經網絡算法計算和探測火災圖像的形成規律和信號特徵,給齣神經網絡的具體結構和輸入輸齣單元的設計方案。併對一繫列的火災樣本圖像和榦擾圖像進行實驗。研究結果錶明:此方法能更有效地減少火災的誤報警率,提高火災報警的準確率。

As for the duality of fire,namely randomness and determinism,the intelligent building automatic fire alarm system has the important task that transforms the randomness accurately to the another side with relative se-curity in the fire detection.Therefore,in this paper,the BP neural network algorithm was used to calculate and detect the developing rule and signal feature of the fire image.It gives the detailed structure of the BP nerve net and the concrete design scheme of input and output layers.Then a series of sample images of fire and interfer-ence images have been experimented.Experimental results show that fire detection algorithm based on the BP neural network is more effective to reduce the fire false alarm rate,and improves the accuracy of the fire alarm.
