Distance measuring system and distance measuring method

Abstract

The invention relates to a distance measuring system which comprises a distance measuring device and terminal equipment, the distance measuring device comprises a measuring wheel, a rotating shaft arranged on the measuring wheel and an electronic counter connected with the rotating shaft and used for obtaining distance information of the measuring wheel, and the distance measuring device or the terminal equipment further comprises an angle sensor. The terminal equipment and the distance measuring device are respectively provided with communication modules. And the terminal equipment comprises a data processing module which is configured to generate an advancing track diagram of the measuring wheel in real time according to the distance measurement information from the electronic counter and the angle information of the angle sensor. The invention further discloses a distance measuring method based on the distance measuring system. According to the invention, on the basis of realizing the distance measurement function, the drawing of the advancing track can be generated in real time, and the working efficiency is effectively improved. When the distance measusring device is matched with the marking device, the function of marking on a construction site according to a pre-designed drawing can be achieved, and the distance measuring device has the advantages of being simple in structure, light, 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.
