Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of underground pipe gallery fire warning, in particular to an underground pipe gallery sectional fire warning device based on temperature sensing control. BACKGROUND

[0002] The underground comprehensive pipe gallery refers to a structure and auxiliary facilities arranged below the ground of a city for accommodating two or more public facility pipelines or professional pipelines. Due to the complex internal environment of the pipe gallery, there are poor ventilation conditions, relatively closed space and other characteristics. Once a fire occurs, the fire is likely to spread rapidly, and the rescue is difficult, which will have a serious impact on the operation of the city and the life of the people.

[0003] The existing underground pipe gallery fire warning methods mainly include smoke sensing and temperature sensing. The smoke detector issues an alarm when the smoke density reaches a certain level, but for some early fires, especially the smoldering stage, the amount of smoke produced is small, and it may not be able to detect in time. The temperature detector detects the change of the environment temperature to determine whether a fire occurs. However, the traditional temperature detector is usually fixedly installed at a position, and the detection range is limited, which has limitations for monitoring large areas in the pipe gallery, and cannot comprehensively and timely grasp the temperature conditions of each section of the pipe gallery. In addition, the existing fire warning devices mostly lack flexible mobile monitoring capability, and it is difficult to dynamically and comprehensively detect different areas of the pipe gallery.
