摘要:
传统自动喷水灭火系统依赖热敏元件被动触发，存在响应滞后、定位模糊、水损严重等问题，难以适应现代复杂建筑的精准控火需求。为此，在揭示既有火灾定位技术局限性的基础上，基于实体火灾试验，提出了一种基于热电偶温度传感器的火源定位新方法，并构建了适用于小规模火灾的定位模型，旨在通过火灾定位技术的革新，提升智慧喷水系统的响应速度与灭火效能，减少资源浪费。该模型的喷头保护半径计算值与实际值的相对误差控制在15%以内，绝对误差不超过0.45 m，可显著提升火灾早期定位精度，契合绿色建筑节水减排目标，推动消防技术向高效化、智能化转型。
Abstract:
Traditional automatic sprinkler systems rely on passive triggering of heat-sensitive elements, suffering from issues such as response lag, ambiguous fire localization, and severe water head loss, making it difficult to meet the precise fire control requirements of modern complex buildings. To address these challenges, this paper, based on revealing the limitations of existing fire localization technologies and through full-scale fire tests, proposed a novel fire source localization method using thermocouple temperature sensors. A localization model suitable for small-scale fires was constructed, aiming to enhance the response speed and fire extinguishing efficiency of intelligent sprinkler systems through innovations in fire localization technology, while reducing resource waste. The relative error between the calculated value and the actual value of the nozzle protection radius of the model was controlled within 15%, with an absolute error not exceeding 0.45 m. This significantly improves early fire localization accuracy, aligns with the water-saving and emission-reduction goals of green buildings, and promotes the transformation of fire protection technology toward greater efficiency and intelligence.
