7) if do not meet above-mentioned steps 3, step 4 and step 5 continuously, then continue sampling and judge, do not report to the police.
Climb rail derailment course in conjunction with wheel 5a, it is as follows that its derailing detects specific descriptions:
One, normal condition
As shown in Figure 7, when railway vehicle normally runs in orbit, wheel 5a does small size serpentine locomotion centered by rail 10 line of centers, and wheel 5a wheel rim does not cling on rail 10, and wheel 5a is relative to the Uplifting amount h of rail 10
mbe zero;
Two, wheel rim reclines state
As shown in Figure 8, if under certain specified conditions, wheel 5a is very large to the transverse force of rail 10, and wheel 5a is very little to the vertical force of rail 10, so that the contact point that wheel 5a is new in rolling process shifts to wheel rim top gradually, wheel 5a raises gradually, and wheel 5a is relative to the Uplifting amount h of rail 10
mvalue increases gradually, works as h
mvalue is greater than safety value, this secondary data of processor for recording h
m, be labeled as 1 time;
Three, continue to climb track-like state
As shown in Figure 9, if the position of contact point arrives the flex point on wheel rim arc surface on wheel rim, namely during maximum some in wheel rim root and wheel rim inclination angle, circular sliding slopes place, middle part, climb the transformation point of rail with regard to arrival.If transverse force reduces or vertical force increases before arrival transformation point, then take turns still may slide downward, return to original settling position.After contact point postcritical, if the change of transverse force, vertical force is little, wheel 5a likely climbs up rail 10 gradually and derails.
In this process, wheel 5a is relative to the Uplifting amount h of rail 10
mvalue continues to increase, h
m+1be greater than h
m, be labeled as 2 times, h
m+2be greater than h
m+1, be labeled as 3 times, then send alerting signal;
Four, derailing state
As shown in Figure 10, if wheel 5a continues to climb rail, rail 10 will be climbed up until wheel rim top reaches rail 10 end face and derails.
