The invention relates to a cable crane anti-collision regulation and control method for improving the positioning precision by adopting a combined positioning mode. The method comprises the following steps: carrying out operation conflict detection on a cable crane and an obstacle by adopting a collision detection method; judging the type of the obstacle according to the position coordinate information provided by the positioning server; for the condition of a fixed obstacle, according to the current speed of the cable crane, calculating the braking distance and the time required for braking at the speed, and comparing the braking distance and the time with the early warning distance and the early warning time of the cable crane set by the system respectively; and determining an adjustment object according to the anti-collision priority adjustment rule of the cable machine under the condition of moving an obstacle, and taking regulation and control measures for the adjustment object to prevent collision. According to the invention, possible collision conditions are detected, anti-collision regulation and control of the cable crane are realized, and safe and efficient operation of the cable crane in the construction process is ensured; a combined positioning mode is adopted, the combined positioning precision is high, the real-time performance is good, and the positioning precision reaches the centimeter level.
