When turning to, oil cylinder drives detection plate 1 to move, and it is electric that proximity switch 32 detects that spacer portion 122 obtains,
Detection signal P=1, due to sign mutation, triggering timing program, starts timing；When turning to α
During angle, proximity switch is in again detection breakthrough portion 121, proximity switch dead electricity, detects signal
P=0, now stops timing, obtains timing time t.
Timing time t compares with setting time t1 and t2:
1) as t ＞ t2, turning velocity is suitable, and risk of not tumbling turns to safety；
2) as t1 ＜ t ＜ t2, turning velocity is too fast, now inquires about GES, when speed v
＜ v1, speed is relatively low, is difficult to tumble, and therefore turns to safety, does not reports to the police；When speed v
＞ v1, speed is too fast, and it is too urgent to turn to, and is easily generated and tumbles, this alarm, governed engine speed,
And limit bring to a halt；
3) as t ＜ t1, turning velocity impersonal force can and, it is judged that for turning to round about, neglect
Slightly this time detection, does not reports to the police.
Continue to turn to, then proximity switch will be changed into obtain electricity condition by power failure state, hence into
Next time-count cycle, is constantly monitored turning velocity.
