The high temperature control unit c1 is used for controlling the temperature signal collected by the high temperature sensor c and the change adjustment of the high temperature. The reason why the temperature controller 11 is provided with the plurality of temperature hierarchical control units is that the plurality of temperature hierarchical control units are matched with application equipment in a real working environment, such as the application of the temperature hierarchical control units in an automobile engine, and the stop of the automobile engine caused by different temperatures may correspond to different automobile faults, so that the plurality of temperature hierarchical control units are convenient for distinguishing and collecting the reason that the temperature sensor 10 is used for quickly distinguishing the stop of the engine caused by high, medium and low temperatures.
