Measuring wheel used for measuring distance and area and measuring method thereof

Abstract

The invention provides a measuring wheel used for measuring distance and area and a measuring method thereof, belonging to the technical field of measuring wheel. The invention solves the problem that the traditional measuring wheel can not directly measure area. The measuring wheel used for measuring distance and area comprises a measuring wheel, a wheel frame arranged on the measuring wheel and a handle connected onto the wheel frame, an operational display interface is arranged on the handle, a sensor used for detecting number of turns of rotation of the measuring wheel, the handle is also internally provided with a central processor, the sensor and the operational display interface are all connected with the central processor, the handle is also internally provided with a storage and a geomagnetic field sensor which are connected with the central processor, the central processor is used for receiving a turn number signal and an angle signal, and area surrounded by the way that the measuring wheel rolls for a circle around the ground is calculated according to circumference of the measuring wheel, number of turns of the measuring wheel and steering angle of the measuring wheel, and a result is delivered to the operational display interface to be displayed. The measuring wheel provided by the invention can measure distance and also can directly, rapidly and accurately realize area measurement.

Description

technical field [0001] The invention belongs to the technical field of measuring wheels, and relates to a measuring wheel for measuring distance and area and a measuring method thereof. Background technique [0002] The measuring wheel is also known as the distance measuring wheel or the distance measuring vehicle, and its basic function is to measure the distance. In actual use, it is often necessary to measure the plot area with the existing measuring wheel. In the existing measuring wheels, the area of ​​irregular plots cannot be directly measured. One of the reasons is that the existing measuring wheels work well in some fields that do not require area measurement, such as the wiring operation field. In the field of wire wiring operations, only distance parameters are required, that is, how many wires are needed for this project can be predicted. [0003] However, in another important application field of the measuring wheel, such as land area measurement, real estate ...

AI Technical Summary

Problems solved by technology

Its disadvantages are (1) the signal accuracy of civilian GPS satellites is limited. It is generally believed that the single-point positioning accuracy of civilian GPS satellites is 50 meters, and the scope of application is limited; The positioning accuracy can meet the requirements of some applications, but it has the following disadvantages: the GPS signal is affected by the atmospheric environment, etc., the positioning accuracy is affected, and there will be a large drift phenomenon

But its one disadvantage is that it consumes a lot of power

The overall price of GPS area measuring instruments is relatively high; especially the high-precision GPS receiving modules need to be imported, which is expensive
