Real-time distance measuring device, system and method for high-grade leveling

Abstract

The invention discloses a real-time distance measuring device, system and method for high-grade leveling, and belongs to the field of horizontal distance measurement. In order to solve the problems that in the prior art, the sight distance error is large before and after level gauge measurement, the consumed time of a distance measuring instrument is long, and power consumption is high, the invention provides a real-time distance measuring device, system and method for high-grade leveling; the device comprises an upper shell and a lower shell, circuit boards are arranged in the upper shell andthe lower shell, and antennas are installed on the circuit boards; each circuit board further comprises a man-machine module, a control module, a sensing module, a monitoring module and a power supply module, when the device measures the distance, the antenna with the optimal signal is calculated through an antenna switching algorithm, the long distance measuring time due to bad single antenna signal is avoided, the distance measuring result can be obtained more accurately and rapidly, meanwhile, the power consumption of the device is reduced, and installation is convenient; and the device can be installed on a level gauge for common movement.

Description

technical field [0001] The invention relates to the field of horizontal distance measurement, and more specifically, relates to a real-time distance measurement device, system and method for high-level level measurement. Background technique [0002] Leveling is one of the basic methods to determine the elevation of engineering ground points, and it is also a high-precision and commonly used method in elevation measurement. Leveling provides basic data for construction stakeout, equipment installation, deformation monitoring, analysis and forecasting. Leveling is one of the most important tasks in the process of land and boundary survey, engineering topographic map survey, geological survey, engineering construction, completion acceptance and building deformation monitoring. [0003] In order to achieve high-precision leveling, currently only high-precision electronic levels can be relied on to carry out elevation transfer measurements step by step along the engineering lin...
