耗费时间

To assure extinguishing efficiency of the fire suppression system on fire, the system is requested to perform enclosure integrity test in accordance with NFPA 2001 standard. For reducing the high cost of test, this thesis proposes a method of using backpropagation neural network to simulate the field test and estimate the retention time when the suppressant is discharged, the result can be a reference of self-survey and the improvement prior to fire inspection.

为确认气体自动灭火系统安装后，是否能於火警发生时立即发挥灭火功效，我国内政部消防署要求业主须依照美国国家消防协会NFPA 2001规定，进行防护区空间气密测试，然实际於现场进行气密测试耗费人力并且所费不赀，本论文提出以倒传递类神经网路模拟现场气密测试，估测灭火气体释放后防护区气密时间，以作为消防检查前自主检查及改善之参考，确保火灾发生时系统能达到真正灭火的功能而防患未然。
