Embodiment

[0052] In this embodiment, the guide rail 8 and the slider 9 use the common HGW-25HC slider to cooperate with the HGW-25HC guide rail with a length of 1000mm, and the slider 9 can slide smoothly on the guide rail 8; The processing core, ultrasonic transceiver 3 adopts HC-SR04 ultrasonic transceiver, the distance s from the ultrasonic transmitting hole to the receiving hole of this type of ultrasonic transceiver is a fixed value of 27mm, and the temperature sensor adopts DS18B20 temperature sensor. The measurement steps are:

[0053] a. Adjust the guide rail 8 of the measuring instrument to be horizontal;

[0054] B. open the switch of single-chip main board 7, make it energized, the digital display tube on the single-chip main board 7 can show the vertical distance L of current ultrasonic transceiver 3 and the land surface, record this numerical value; Wherein,

[0055] Single-chip microcomputer main board 7 controls ultrasonic transceiver 3 emitting holes to send ultrasonic ...

Abstract

The invention relates to the technical field of measurement, in particular to an agricultural land flatness measurement instrument and method. The agricultural land flatness measurement instrument comprises a supporting frame part, a single-chip microcomputer (1), an ultrasound transceiver (3), a temperature sensor and a digital display tube. According to the supporting frame part, a guide rail supporting leg (11) is connected with a guide rail supporting cross beam (6), and the connecting position is wrapped with a fastening piece (10) and fixed through a handle (5); the guide rail supporting cross beam (6) is matched with a guide rail (8) through a hole; a sliding block (9) is arranged on the guide rail (8) in a sliding mode; the single-chip microcomputer (1) is installed on a single-chip microcomputer main board (7) arranged above the sliding block (9), and the single-chip microcomputer main board (7) is provided with the temperature sensor and the digital display tube; the ultrasound transceiver (3) is arranged below the sliding block (9). The agricultural land flatness measurement instrument can work in a relatively bad environment while not affecting the accuracy of measurement, can carry out multi-point measurement at a time, and is high in efficiency, reliable in data, small in size, easy to assemble and portable.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a measuring instrument for the flatness of agricultural land and a measuring method thereof. Background technique [0002] Land levelness is an important indicator of agricultural machinery evaluation. It not only reflects the operation quality of tillage machinery and seed bed preparation machinery to a certain extent, but also becomes an important factor in the study of seed covering depth, soil wind erosion and soil water-saving irrigation. [0003] Traditional land levelness measurement usually uses direct contact measurement methods, such as ruler rod method, inserted rod method, chain method, contact needle measurement method, etc. These measurement methods not only require a lot of physical labor, but also are easy to measure directly on the land surface Destroying the original measurement surface will reduce the reliability of the data. Therefore, non-contact measurem...
