Temperature-sensing fire detector and fire monitoring method

Abstract

The invention provides a temperature-sensing fire detector and a fire monitoring method. The temperature-sensing fire detector comprises a processing unit and a plurality of detection units. The detection units are used for contact type temperature sensing and / or non-contact type temperature sensing. The detection units directly connected with the processing unit are direct detection units, the detection units which are not directly connected with the processing unit are indirect detection units, the processing unit is connected with the plurality of direct detection units to form a star-shaped structure by taking the processing unit as the center, or the direct detection units and / or the indirect detection units are connected with the plurality of indirect detection units; each detectionunit is provided with an independent number which can be identified by the processing unit; and the processing unit is used for carrying out fire monitoring according to signals transmitted by the detection units and positioning fire occurrence positions according to the independent numbers. In this way, on the condition that the using amount of the detection units is saved as much as possible, wide-range fire monitoring and alarming can be effectively achieved, the engineering equipment cost can be reduced, and the fire occurrence position can be located in time.

Description

technical field [0001] The present application relates to the field of sensing technology, in particular, to a temperature-sensitive fire detector and a fire monitoring method. Background technique [0002] At present, a large number of cable-type linear temperature-sensitive fire detectors are used for fire detection at home and abroad. The cable-type linear temperature-sensitive fire detector uses temperature-sensitive materials to process cables, and then coats the cables with sheaths. The detection principle is generally the principle of impedance change (that is, the detector is made of cable materials with special temperature coefficients). into, and the detection circuit judges whether there is a fire on the scene according to the impedance change of the cable). [0003] In the current engineering application, the cable-type linear temperature-sensitive fire detector is restricted by its structure and detection mechanism. It is usually necessary to arrange a large n...

Problems solved by technology

[0003] In the current engineering application, the cable-type linear temperature-sensitive fire detector is restricted by its structure and detection mechanism. It is usually necessary to arrange a large number of cable-type linear temperature-sensitive fire detectors (the monitoring range of cable-type linear temperature-sensitive fire detectors is near the location where they are installed), which increases the cost of engineering equipment and reduces the cost performance of engineering applications

Moreover, it is difficult for the cable-type linear temperature-sensitive fire detector to effectively locate the location of the fire, which is not conducive to timely fire rescue and rescue.
