Embodiment 1

[0035] Such as figure 1 As shown, a Beidou / GNSS high-precision rapid positioning equipment used in the construction process includes a support 100, and a leveling device 502 is arranged above the support 100. The leveling device 502 consists of a chassis, a top plate, and a chassis and a top plate. Composed of connecting rods between them; above the leveling device 502, an electronic bubble 505, a vibration detection device 506, a laser distance measuring device 504 and a prism 2 are arranged; the top of the leveling device 502 is provided with a satellite signal receiver 1; a laser range finder 504 , the prism 2 is arranged between the leveling device 502 and the satellite signal receiver 1 .

[0036] In order to further explain this embodiment, it should be noted that, as figure 1 , when the support 100 is a hollow tubular structure, the support 100 is filled with sand, which is used for foundation pit monitoring and other projects that require continuous monitoring. A forc...

Embodiment 2

[0042] A Beidou / GNSS high-precision and rapid positioning method used in the construction process, the specific steps are as follows:

[0043] 1) The satellite signal receiver in the Beidou / GNSS high-precision positioning equipment receives Beidou satellite and other satellite signals; the laser rangefinder 504) measures the horizontal distance between two high-precision positioning equipment; the vibration detection equipment measures the construction vibration;

[0044] 2) Computer input calculation parameters;

[0045] 3) Data transmission: the wireless transmission equipment automatically transmits the satellite signal received by the satellite receiver 1 and the horizontal distance measured by the laser rangefinder d ), the construction vibration data measured by the vibration monitor are sent to the computer;

[0046] 4) The computer reads the satellite signal data for calculation. Based on the Beidou / GNSS static relative positioning, Kalman filter is used to estimate, ...

Abstract

The invention discloses a Beidou / GNSS high-precision rapid positioning device and method for a construction process. Through the Beidou / GNSS high-precision rapid positioning device, a computer and a construction process Beidou / GNSS high-precision rapid algorithm, the fixed-point high-precision positioning of a construction operation area is rapidly achieved. The device has the advantages of stronganti-interference capability, high positioning speed and high precision.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a Beidou / GNSS high-precision rapid positioning device and method used in the construction process. Background technique [0002] The existing construction measurement is still based on the traditional "cumulative measurement" mode, even if the most advanced optical / laser measurement equipment is used, there are always multiple conversions and progressions. As the construction field continues to expand and become higher, there will inevitably be a phenomenon of greater precision errors, which will affect the use and function of the building. [0003] It can be seen that introducing new measurement technology, changing the traditional idea of ​​using a single optical measurement and positioning, and establishing a relatively stable high-precision mobile control field in the construction field are necessary and sufficient conditions for realizing the digitization of th...
