Problems solved by technology

[0002] When the overall steel platform used in the construction of high-rise buildings is climbing, the steel platform is supported by several hydraulic ejector rods. The bottom of the hydraulic ejector rods is located on the completed reinforced concrete surface. The guide column climbs upwards. Since the steel platform is a rigid whole, if the hydraulic ejector rods have inconsistent elevations, different running speeds, and non-vertical running directions, it will make it difficult to lift the overall steel platform or cause safety hazards for construction.
[0003] In order to ensure the stability of the steel platform in the lifting operation or static operation state, the existing technology generally uses ultrasonic distance measurement to detect the position of the hydraulic ejector rod, but due to the harsh environment of the construction site, rain, fog, and dust will affect the ultrasonic wave. The interference is very large, resulting in unstable measurement results or large deviations in measurement values

Abstract

The invention relates to a distributed multi-source information collaborative positioning system and method. The system comprises a transmitting module located on a first surface, a feedback module located on a second surface opposite to the first surface, and a server which is in communication connection with the transmitting module and the feedback module; the transmitting module comprises a first data processing unit, a first radar unit and a laser emitting unit; and the feedback module comprises a second data processing unit, a second radar unit and a laser detection unit. According to the distributed multi-source information collaborative positioning system and method, the accuracy of a measurement result of a position relation between the first surface and the second surface is high; and the collaborative positioning system and method is suitable for various scenes for measuring the position relation between the two opposite surfaces.

Description

technical field [0001] The invention relates to the technical field of distance measurement and calibration, in particular to a distributed multi-source information collaborative positioning system and method. Background technique [0002] When the overall steel platform used in the construction of high-rise buildings is climbing, the steel platform is supported by several hydraulic ejector rods. The bottom of the hydraulic ejector rods is located on the completed reinforced concrete surface. The guide column climbs upwards. Since the steel platform is a rigid whole, if the hydraulic ejector rods have inconsistent elevations, different running speeds, and non-vertical running directions, it will make it difficult to lift the overall steel platform or cause safety hazards for construction. [0003] In order to ensure the stability of the steel platform in the lifting operation or static operation state, the existing technology generally uses ultrasonic distance measurement to...
