s3, when the wind speed sensor senses that the wind speed is higher than 28.4m/S or one of the tension sensors senses that the tension is 0; the PLC controller controls the electromagnet to start and attract the electromagnet to the baffle plate, controls the telescopic cylinder to extend out, and inserts the inserted link into the insertion hole; the main hoisting mechanism stops running;
s4, when the wind speed sensor senses that the wind speed is higher than 32.6m/S, the steel rope of the main hoisting mechanism is gradually loosened;
s5, when the wind speed is lower than 32.6m/S, the steel rope of the main hoisting mechanism is gradually tensioned, and when the wind speed is lower than 28.4m/S, the PLC controls the electromagnet to be closed and the telescopic cylinder to retract, and the inserted rod withdraws from the insertion hole.
