The invention relates to a cooling system operated by an ARM processor. The ARM processor is provided with a core unit, a WIFI assembly, a duplex transmission end. The cooling system comprises an analog assembly and an input interface assembly for transmitting messages with the ARM processor; the analog assembly is connected with a heat monitor I and a heat monitor II correspondingly; the duplex transmission end is connected with motor processors correspondingly; and the input interface assembly is provided with keys for controlling the operation and termination of exhaust machines, an obtaining valve for obtaining the types of the exhaust machines, and an LED for displaying operation attributes of the exhaust machines. The problems in the prior art that the cost is increased, the difficulty of wiring erection is increased, the exhaust machines are complicated, and the frequency of implementation and maintenance is increased are solved.
