Description
Technical Field
The utility model relates to an engineering reconnaissance measuring instrument, concretely relates to portable reconnaissance measuring instrument who possesses range finding function.
Background
Current engineering survey measurement techniques include rangefinders, total stations, and RTKs.
1. A distance meter:
the structure principle is as follows: the distance measuring instrument is a tool for measuring length or distance, and can be combined with angle measuring equipment or a module to measure parameters such as angle, area and the like. The range finder is in many forms, and is usually an elongated cylinder, which is composed of an objective lens, an eyepiece, a display device, a battery, and the like. The pulse range finder is commonly called a laser range finder because a laser beam has a good directivity and a single wavelength, and a photoelectric range finder generally uses a laser beam as a modulation target.
Problem and defect: most of the existing distance measuring instruments are handheld distance measuring instruments, and whether the instruments are placed horizontally or not during measurement cannot be guaranteed, so that the horizontal distance measurement is inaccurate; when the ground object targets with different heights are measured, the horizontal distance and the height of the targets cannot be measured due to the fact that the vertical angle of the distance meter cannot be measured. The problem is particularly prominent when the target position forms are diversified in field survey and measurement.
2. Total station:
the structure principle is as follows: the total station is a high-tech measuring instrument integrating light, mechanical and electrical functions, and is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measuring functions. Compared with the optical theodolite, the electronic theodolite changes the optical scale into the photoelectric scanning scale, and replaces manual optical micrometer reading with automatic recording and displaying reading, so that the angle measurement operation is simplified, and the generation of reading errors can be avoided.
Problem and defect: the total station is a high-technology measuring instrument, although the measuring precision is high, the price is expensive, and the total station has no economy for ordinary low-precision measurement; the total station is heavy and needs to be matched with a tripod for use, so that the total station is not convenient to carry during field investigation operation and influences the working efficiency; the total station is relatively complex in principle structure, and surveyors need to use the instrument after professional training, so that the requirement on the personnel operating the total station is high.
3、RTK：
The structure principle is as follows: RTK (Real-time kinematic) is a new commonly used satellite positioning measurement method, which adopts a carrier phase dynamic Real-time difference method, is a difference method for processing carrier phase observed quantities of two measurement stations in Real time, and sends carrier phases acquired by a reference station to a user receiver for difference solving of coordinates. RTK is a measuring method capable of obtaining centimeter-level positioning accuracy in real time in the field, and greatly improves the operation efficiency.
Problem and defect: the field exploration environment is severe, and the RTK cannot receive satellite differential signals due to the thick vegetation environment, so that the coordinate data of a target cannot be measured; for areas such as steep side slopes, cliffs, landslides and the like, people cannot carry RTK instruments to the top of the slope or the top of the cliffs to measure, and measurement in field exploration is limited.
In summary, when surveying geological features of areas such as side slopes, cliffs, landslides and the like in the field, geometric information of a survey target needs to be acquired. The measuring instruments are limited by functions and environments when used for field investigation, and cannot well complete measuring tasks. It is therefore desirable to provide a portable laser rangefinder for engineering surveying.
