| 中文摘要: |
| 介绍了基于CCD成像的多角度激光散射的火灾探测技术。本技术采用数字图象、神经网络等处理技术 ,对不同的燃烧方式设定相应的灵敏度 ,能准确识别灰尘、飞虫和水蒸汽等非火灾的干扰因素 ,实现了在复杂环境中稳定可靠的超早期的火灾探测和报警 ,改变了现有探测技术在提高灵敏度后却只能用于洁净环境、对恶劣环境只能通过提高报警阈值等手段来解决的被动局面. |
| 英文摘要: |
| For existing technology, only in clean environment can the high sensitivity be used and functioned, and in complex environments the alarm threshold should be changed at any time. This paper introduced a new fire detecting technology based on multi angle laser scattering with digital and neural CCD image procession. This technology can detect the signals due to non fire factors such as dusts, insects and vapor by setting different sensitivities for different combustion styles. The reliable early stage detection of fires is thus realized for complex environments. |
