Fire control system with the features of numerous functions, complex technology and poor working conditions requires high- precision temperature parameters and wide temperature test range. This paper presents a method of PTlOOO-based temperature test and designs a fire control temperature test system. MATLAB is used to do linear processing on collected data, making the temperature cal- culation easier ; IFC Algorithm is applied to quickly filter the larger temperature error value of the system, achieving the precise treat- ment on the data. Experiments show that the accuracy of the fire control temperature measurement system reaches 0.2 ℃, which is suitable for a variety of high-precision temperature testing, having a good application value.
