Embodiment
[0018] RTK-based measurement and control method for engineering arbitrary curve sliding and translation refer to figure 1 , the steps are as follows:
[0019] 1) Large-scale building components are constructed on moving sliders on several sliding tracks. The sliding track can be any curve, and hydraulic thrusters are used to drive the sliding of large-scale building components;
[0020] 2) GNSS receivers are divided into mobile stations and reference stations. The number of GNSS receivers is N, and N is equal to the number of sliding orbits plus 1. One of the GNSS receivers is fixed on a known coordinate point as a reference station. The remaining N-1 GNSS receivers are fixed on the sliding objects in each track as mobile stations;
[0021] 3) The hydraulic propeller is controlled by the hydraulic station; the control computer controls the hydraulic station and the GNSS receiver through wireless signals, corrects the starting point, checks the working condition of the hydraul...

The invention discloses a synchronous measurement and control system for slippage and translation of an engineering random curve based on RTK (Real Time Kinematic) and a method thereof. The synchronous measurement and control system comprises a hydraulic pusher, a slippage rail, a hydraulic station, a GNSS (Global Navigation Satellite System) receiver and a control computer, wherein a slippage data of a large construction on each rail collected by the GNSS receiver is sent to the control computer by a wireless communication module; and after a control element calculates, the control computer controls the hydraulic pusher to act, so that an object is moved on the slippage rail. After a synchronous measurement and control method for the slippage and translation of the engineering random curve based on RTK is used during a slippage construction process, the displacement of each pushing point is synchronous, the whole structure is under a translation state, a structural attachment stress is prevented from generating and the whole body is protected from being damaged.
Description
technical field [0001] The invention relates to the field of building construction, and specifically provides an RTK-based system for synchronous measurement and control of arbitrary curve sliding and translation in engineering and a method thereof. Background technique [0002] At present, there are many large-scale venues in China, such as airports, railway stations, stadiums, etc., and the roofs used generally have relatively large spans, areas, and self-weights. With the traditional construction technology, multiple steel structure assembly platforms need to be built on the construction site. It is difficult to further improve the installation accuracy of the project, and the safety of construction operations is also low. In addition, it will cause a lot of waste of temporary support rods. At the same time, since the bearing capacity of the roof of the warehouse is only about 2.5 tons per square meter, and the overall roof is generally greater than 500 tons, it is not po...
