In view of present security problems existing from traveling block’s speed by manual control, a kind of energy-saving automatic anti-collision scheme is put forward. An analysis of the transmission system structure of ZJ70L-ZPD oil drilling rig can obtain the influence that the alteration of diesel engine speed results in the alteration of speed of traveling block rising or falling. Fuzzy control system is established by fuzzy control strategy that concludes input quantity rotation speed deviation and deviation ratio and output quantity throttle aperture, which creates fuzzy control data sheet by offline calculating. Decelerate gradient on the set position of decay area was calculated by detecting the speed of the braking point, through the way that queries the fuzzy control table to real-time adjust output quantity of throttle size so as to achieve the purpose of anti-collision. This kind of anti-collision scheme reduces energy consumption by figuring out the real-time speed deviation to adjust fuel charge, avoids the braking system power dissipation off the kinetic energy by means of frictional heat when traveling block rising, provides new ideas and methods to solve problem of crown block anti-collision.
