In the embodiment of the invention, (1) before the system is executed, four initial data are acquired and recorded in consideration of the difference between the top drive and the derrick individual: firstly, measuring forward-tilting and neutral position returning time of the hoisting ring according to the actual situation of top drive, and recording the forward-tilting time value and the neutral position returning time value of the hoisting ring; secondly, recording the distance between the second-layer platform and the top drive body; thirdly, recording the distance between every two five magnetic steels; fourthly, recording the distance between each magnetic steel and the two-layer platform. Wherein the position of the two-tier platform is a known absolute position relative to the ground. And finally, inputting the data into the central processing unit 1, so that a collision speed critical value of the top drive body 8 passing through different magnetic steel 7 detection points can be obtained, and in order to fully consider the influence of actual working conditions, the central processing unit 1 needs to introduce engineering safety factors when calculating the collision speed critical value.
The collision speed threshold value is specifically calculated according to the following formula:
as shown in FIG. 5, Δ S is known1、ΔS2、ΔS3、ΔS4、ΔS5Respectively, the distances, t, between the two-layer platform and the different magnetic steels 7 (i.e. 5 response detecting points P1-P5)BThe forward inclination and neutral return time of the hoisting ring are shown.

When the top drive body descends to pass through a fifth magnetic steel 7.5 detection point, if the descending speed of the top drive body (theoretically, the descending speed is constant under the condition that the top drive driller normally operates) is greater than a collision speed critical value at the moment, the top drive driller box gives out a rapid acousto-optic alarm, otherwise, the top drive driller box gives out an audible alarm to prompt an operator to pay attention to the top drive position and the hanging ring state at the moment; when the top drive body descends to pass through the fourth magnetic steel 7.4 detection point, if the descending speed of the top drive body is larger than the collision speed critical value at the moment, the top drive hanging ring automatically retracts to the collision safety distance, otherwise, the top drive driller box gives out a rapid acousto-optic alarm to prompt an operator to pay attention to the top drive position and the hanging ring state at the moment, and the operator judges and executes the hanging ring circulation to the middle position by himself.
That is, if upsilon ≧ k upsiloncnThe top drive driller box sends out a response warning prompt, k is a safety engineering coefficient introduced by the invention, upsilon is a top drive uplink speed or a downlink speed, and upsilon iscnAnd representing the collision speed critical value of each detection point, wherein n is 1,2,3,4 and 5.
Wherein, the warning of formula is reminded gradually in the warning protect function adoption of preventing bumping, according to the safe risk degree by low to high execution operation: the alarm device can give an alarm by sound, prompt sound and light and automatically return to the collision safety distance. The warning reminding protection mode strengthened gradually can provide a more reasonable prompt signal for operators, and the operators can clearly know the current equipment operation safety risk.
