The invention provides an engine state monitoring method and system, and the method comprises the steps: obtaining a simulation result obtained by simulating the stress of each supporting leg of an engine in advance, and taking the simulation result as a first alarm value; the engine with the supporting legs adjusted in advance is operated, in the operation process of the engine, a strain gauge is used for collecting stress-strain signals of each supporting leg of the engine under the current working condition, and each stress-strain signal is converted into a stress value; comparing the stress value of each supporting leg with the second alarm value; if the stress value of the supporting leg exceeds the second alarm value, executing an alarm strategy or giving an alarm; comparing the stress value of each supporting leg with the first alarm value; and if the stress value of the supporting leg exceeds the first alarm value, turning off the engine and giving an alarm. Through the method, the stress condition of
