The drilling rig auxiliary operation platform is mainly used for simulation training of the operator for the drilling rig assembly, so that the operator can quickly be familiar with the operation and usage of the drilling rig, fully master the performance of the assembly and improve the training effect and level. Semi-physical simulation was adopted for development of the drilling rig auxiliary operation platform, namely, the simulation plan is employed, while the operation results are feedback to the trainees through TV or projection display equipment. The real-time simulation equipment completes command control and effect display, the interface equipment completes data acquisition and communication, and the simulation machine realizes virtual drilling rig simulation operation.
