Detailed Description
The present invention is described in further detail below with reference to the attached drawing figures.
As shown in fig. 4, the present invention provides a pile sinking positioning system suitable for deep and remote sea work, comprising: install GNSS receiver 1(GPS receiver), laser range finder 2, biax inclination sensor 3, display 5 and host computer 4 on pile driving vessel, wherein, host computer 4 respectively with GNSS receiver 1 (global navigation satellite system), laser range finder 2, biax inclination sensor 3 and display 5 are connected.
Before the whole scheme is implemented, firstly, the hull to be measured needs to be measured, because a certain error exists between the design point and the factory welding of the piling ship, and in order to avoid the error, the positioning point of the hull needs to be measured again. The total station is used to determine the hull coordinates of key points on the pile driving vessel. The piling ship is parked in the dock, and the relative position between the piling ship and the total station is fixed.
Using total stations at the piling vessel
A datum point can be selected at the stern of a deck keel, the edge coordinates of a ship body are measured in a mode of erecting a prism, then data calculation is carried out, the ship body coordinates of a three-dimensional space rectangular coordinate system which actually takes the center of the ship body as the origin of a coordinate system are deduced, and the ship body coordinates of the distance measuring zero point of each laser distance measuring instrument and the installation parameters of the double-shaft inclination angle sensor are measured and recorded.
All parts of the system can be connected through a comprehensive cable, and the comprehensive cable comprises six types of shielding wires, an RS485 cable and optical fibers. Attached to the operator's station in the cockpit where the three axis inclinometer is mounted, the system connections may be as shown in fig. 4.
The GNSS receiver and the laser range finder can be respectively arranged on a deck and a bow, the upper computer is a computer host arranged in a cockpit console, the upper computer displays the posture of the output pile body through a display, and the upper computer can transmit data messages to appointed data receiving equipment in a TCP message form through the satellite transceiver.
In order to guarantee quality and quantity and complete pile sinking operation in deep and far sea areas, the invention starts from the angle of positioning without a base station in far sea areas, and is implemented by a GNSS receiver and a laser range finder. The method can realize the high-precision positioning without the base station in the deep and far sea area, and solves the problem that the operation radius of an RTK positioning mode is limited.
The working scheme of the system can be as shown in fig. 5. The ship body is differentially positioned in the planetary station through the GNSS receiver, the pile position of the pile 6 is calculated by the upper computer, and the ship is moved and adjusted for obtaining a standard ship body coordinate system. The standard ship body coordinate system is a special case of a real-time ship body coordinate system, namely the real-time ship body coordinate system when the height of the central axis of the ship body is the same as the elevation of the top of a designed pile and the ship body is in a horizontal state. Through continuous ship position adjustment and star station differential positioning, the positioning precision reaches the expected requirement, and the real-time pile position is matched with the expected pile position.
By combining the satellite station difference realization through the GNSS receiver and the pile body positioning realization through the public laser range finder, compared with the traditional RTK-GPS technology, the satellite station difference positioning of the GNSS receiver without the base station gets rid of the constraint of the base station, and the single machine can complete the work of the traditional RTK without being limited by the distance, thereby greatly reducing the field labor intensity of measuring personnel.
