Distance-measuring system and distance-measuring method

Abstract

The invention discloses a distance-measuring system, which comprises a distance-measuring device and terminal equipment, wherein the distance-measuring device comprises measurement wheels, a rotating shaft and an electronic counter, wherein the rotating shaft is arranged on the measurement wheels; the electronic counter is connected with the rotating shaft and is used for acquiring distance information of the measurement wheels; the distance-measuring device or the terminal equipment also comprises an angle sensor; the terminal equipment and the distance-measuring device are respectively provided with communication modules; the terminal equipment comprises a data processing module which is configured to generate an advancing track diagram of the measurement wheels according to the distance-measurement information from the electronic counter and the angle information of an angle sensor in real time. The invention further discloses a distance-measuring method based on the distance-measuring system. A graph paper of an advancing track can also be generated in real time on the basis of achieving the distance-measuring function, so that the work efficiency is effectively improved; when the distance-measuring system is provided and matched with a line marker, the function of marking a line at the construction site according to the graph paper which is designed in advance can be achieved; the distance-measuring system has the characteristics of being simple in structure, light and handy, and flexible.

Description

technical field [0001] The invention relates to the field of surveying and mapping, in particular to a ranging system and a ranging method. Background technique [0002] At present, in almost all aspects of people's life and work, distance measuring devices are needed to measure and plan routes and areas, such as in the fields of construction, road engineering, transportation, pipeline laying, and garden landscapes. The more commonly used distance measuring device is the distance measuring wheel. [0003] The existing distance measuring wheel usually only has the distance measuring function, and its basic principle is to measure the distance by counting the number of turns of the measuring wheel by cooperating with the mechanical gear counter or electronic counter. This measurement method is usually It can only measure the length of the travel track of the measuring wheel between points, and the drawing of the later drawings needs to be generated in sections, which is a was...

[0003] The existing distance measuring wheel usually only has the distance measuring function, and its basic principle is to measure the distance by counting the number of turns of the measuring wheel by cooperating with the mechanical gear counter or electronic counter. This measurement method is usually It can only measure the length of the travel track of the measuring wheel between points, and the drawing of the later drawings needs to be generated in sections, which is a waste of time and has low measurement accuracy. In actual use, only limited functions can be realized.
