The invention discloses a petroleum drilling machine winch lifting and lowering control system and an out-of-control protection method, a visual human-machine interaction device HMI, a remote driller room programmable controller, a winch given handle and a first switch are arranged in a driller room of the control system, and a second switch, a programmable controller and a winch frequency converter are arranged in a VFD electric control room. A winch motor, a winch machine set and a derrick head sheave are arranged in the drilling platform, a roller shaft of a winch machine is connected with the derrick head sheave through a steel wire rope, and a dead line fixer is arranged at the free end of the steel wire rope. The winch motor is in transmission connection with the winch mechanical set, a winch motor sensor is arranged on the winch motor, a roller sensor is arranged on a roller shaft of the winch mechanical set, a head sheave sensor is arranged on the derrick head sheave, and a hanging load sensor is arranged on the dead line anchor. On the basis of the traditional protection means, a new protection method is introduced by monitoring key equipment in real time, so that the operation and protection of the winch hoisting system are more efficient and safer.
