Research on the new digital warning linear temperature detector and its adaptability in cable tunnel fires
In order to solve the problem of traditional linear tem-perature sensing cables being unable to effectively locate and accu-rately warn fires in cable tunnels,a new type of digital linear tem-perature sensing detector is developed.On the basis of traditional temperature sensing cable technology,distributed insertion of fire protection chips is combined with existing thermosensitive materi-als for fire source localization and data processing;Applying multi-source data fusion and adaptive algorithms,considering en-vironmental impacts,and integrating multiple types of data,accu-rate warning is achieved;Upgrade the output warning method,al-lowing multiple devices to observe real-time temperature and tem-perature cloud maps along the cable.After passing the technical index verification of the product,referring to national standards and cable tunnel environment,small fire source performance test-ing,differential temperature alarm performance testing,and boil-ing water testing were carried out.The results showed that the de-tector meets national standards,operates stably in humid and hot environments,and has strong reliability.
