| 摘要： | The AutoPilot 2.0 is a 3D control system that helps increase efficiency and safety. The system is being used to deliver a new poured in-place concrete safety barrier that will separate the eastbound and westbound lanes of the A43 Autobahn. Reinforced concrete barriers offer effective vehicle restraint for road sections carrying heavy traffic and the barrier profile was paved by an SP 25i using slipform paving. The use of AutoPilot 2.0 eliminated the need for the paving crew from VSB infra to set up a stringline for controlling the machine. The automatic 3D control system can optimise slipform paving, allowing accurate stringless control of slipform pavers. It consists of a control system integrated in the machine, a base station and a tablet computer that can be used together with the Field Rover survey pole and on the slipform paver. The system eliminates the need to set up and remove a stringline for conventional machine control, it also reduces project times and costs. The machine is guided by satellite-aided navigation, speeding the workflow and making the operation more efficient, while also allowing tight turns or more complex geometries to be slipformed. |
