Abstract

The invention discloses a crane running route planning method, and belongs to the technical field of crane electrical control. The crane running route planning method is characterized by comprising the following steps that a, a three-dimensional coordinate system is established; b, through a human-computer interface, the space, allowing passage of a hoisted object, of each hole opening is arranged in a PLC according to the three-dimensional coordinate system, and the boundary dimension of the to-be-hoisted object with the maximum size is arranged in the PLC according to the three-dimensional coordinate system; c, a PLC program is compiled; d, according to the walking real-time coordinate values, detected by the PLC, of a cart and a trolley, whether the hoisted objects are in safe areas in the hole openings or not is judged through comparison; and e, the distances from the positions of lifting hooks and steel wire ropes to the edges of the hole openings are calculated through formulas 6-9. According to the method, it can be ensured that a crane safely bypasses obstacles in a running interval, a larger allowable running area is released to the crane, and the operation space and the operation efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of crane electrical control, in particular to a crane operation route planning method. Background technique [0002] Usually, during the operation of hoisting and hoisting operations, the limit positions of crane lifting, cart and trolley operation are set in advance to control the various mechanisms of the crane during operation so as not to exceed the normal operating range. There are also a small number of cranes to achieve further related area prohibition protection in addition to limit position protection by adding some prohibited areas. For crane hoisting operations in some specific occasions, there are special requirements for the prohibited areas of the crane's various mechanisms. For example, in different time periods of the project construction, some temporary supports need to be set up at different heights of the orifices on the site. After the hoisted objects are lowered to the lower part of the...
