8. The method for monitoring and warning fatigue operation of engineering constructors according to claim 7, wherein the step of identifying the eyeball activity, eyeball closure and yawning times in unit time of the constructors in the step3 is as follows:
Step 301: respectively inputting the identity information of each constructor and correspondingly inputting the eye characteristics of the constructors, wherein the eye characteristics comprise the shape of eyes and the opening and closing degree under natural conditions;
Step 302: the facial features and the eye features of constructors are converted into electric signals from image signal transmission through a microprocessor by a camera (1), and the electric signals are transmitted to a first control unit;
step 303: the AdaBoost face recognition system compares the eye features of constructors with the eye features recorded by the system respectively to obtain the closing degree of eyes and the eyeball closing times n1 in a unit time range t1, wherein the eyeball closing time is higher than a preset time t2 and the eyeball closing times are counted; the AdaBoost face recognition system respectively carries out comprehensive record judgment on the opening and closing times and the opening and closing degree of the lips of constructors, so that the times of yawning are judged, and the times are transmitted to a general control center for analysis.

Step 401: the second signal receiving and transmitting system receives the signals transmitted by the first control unit through the first signal receiving and transmitting system, the second signal receiving and transmitting system transmits the signals to the second control unit, and the second control unit analyzes the received eye closing degree information, eyeball closing frequency information and lip opening and closing frequency information;
Step 402: when one item of information exceeds a set threshold, judging to be 1-stage fatigue, when two items of information exceed the threshold, judging to be 2-stage fatigue, when three items of information exceed the threshold, judging to be 3-stage fatigue, and when the eyeball is closed for longer than t 3, judging to be 4-stage fatigue; wherein t 3 is more than or equal to 1s.
