Smoke stove linkage control method

The invention discloses a range hood and stove linkage control method which comprises the following steps that S1, a range hood master controller receives state signals from a stove master controller, and the state signals comprise temperature signals, detected by two temperature detection devices, of two cooking ranges; s2, when the range hood master control receives that the temperature of any cooking range exceeds the threshold temperature, the control parameters corresponding to the cooking range are read; s3, the range hood master control reads a detection value of the smoke sensing detection device and compares the detection value with a smoke sensing threshold value corresponding to the cooking range with the read control parameters, and when the detection value exceeds the corresponding smoke sensing threshold value, the range hood master control controls a smoke exhaust fan to rotate according to the read control parameters; according to the control method for improving and optimizing the smoke-stove
