Problems solved by technology

It can be seen that the linear fire detector using a single temperature sensing element in the prior art cannot accurately measure the temperature T of the heated part of the temperature sensing element and the temperature change rate T', so it cannot be accurately measured in the event of a fire. It is also difficult to pass the two tests of the action test and the non-action test of the linear fire detector according to the technical standards of the linear fire detector

Abstract

The invention relates to a fire detector of complex linear temperature sensing and the alarm method of data fusion. It consists of a linear temperature sensing element A, a linear temperature sensing B, a device of measuring electric signal. The described linear temperature sensing element A and linear temperature sensing element B are set together in parallel. The linear temperature sensing element A and linear temperature sensing element B has a detector and two electrical parameters signal output terminals respectively.
