SRC cycle catalyst temperature testing method and system

The invention relates to an SRC cycle catalyst temperature testing method and system, and the method comprises the following steps: starting a vehicle, starting to operate according to an SRC cycle working condition, and collecting the temperature data of each measurement point of a catalyst; wherein the catalyst is provided with a plurality of measuring sections perpendicular to the axis of the catalyst at intervals in the length direction, each measuring section is provided with a plurality of measuring points at intervals in the radial direction, each measuring point is provided with a first sensor, and the first sensors are connected with a storage module through data communication lines; and comparing the average temperature data of the measurement points, wherein the measurement point with the highest average temperature is the highest temperature position of the catalyst. By selecting a plurality of cross sections on the catalyst and collecting the temperatures of the same cross section at various diff
