Method and device for monitoring deep scarification operation quality

Abstract

The invention discloses a method and device for monitoring deep scarification operation quality. The device comprises a deep scarification sensor and a control mainframe; the deep scarification sensoris used for collecting deep scarification operation state and parameter related data and comprises a first tilt sensor and a second tilt sensor, the first tilt sensor is mounted on a tractor and deepscarification machine traction rod, and the second tilt sensor is mounted on a tractor body; the control mainframe comprises a master control unit and a transmission module, and the master control unit is used for processing data collected pairwise to conveniently acquire real-time tilling depth values and operation state information. By the method and the device for monitoring deep scarificationoperation quality, technical problems of operation depth measurement, effective operation area statistics and operation vehicle Beidou positioning in supervision of deep scarification operation quality of agricultural machinery are solved, and accordingly the defect of poor performance in monitoring of tilling depth and area of a deep scarification machine in the prior art is overcome. The methodand the device are applicable to construction of an agricultural informationized monitoring system, and agricultural production efficiency is improved.

Description

technical field [0001] The present invention relates generally to the field of agricultural machinery controls. More specifically, the present invention relates to a device and method for monitoring the quality of subsoiling operations. Background technique [0002] Subsoiler is a kind of tillage machinery used in conjunction with high-horsepower tractors. It is mainly used for mechanized finishing of inter-row or all-round deep soil cultivation. It has the functions of breaking the bottom of the plow, restoring the structure of the soil plow layer, and improving the ability of soil water storage and moisture conservation. , Eliminate some weeds, reduce pests and diseases, level the surface and improve the standards of agricultural mechanization operations. [0003] The traditional subsoiling operation has various defects in the monitoring of operation quality. For example, the ultrasonic sensor used in the existing patented technology to calculate the tillage depth value i...

AI Technical Summary

Problems solved by technology

[0003] The traditional subsoiling operation has various defects in the monitoring of operation quality. For example, in the existing patented technology, the ultrasonic sensor is used to calculate the tillage depth value, which is affected by the unevenness of the ground and the accumulation of straw and manure, which makes it difficult to reflect the authenticity of the depth.

In contrast, the deep loosening operation using the image analysis method obtains the operation depth through image sampling and comparison, but requires a high-level algorithm, which is not easy to apply and promote

In addition, the subsoiling detection technology of the single inclination sensor type cannot monitor the change of the horizontal state of the subsoiling machine, and cannot obtain accurate and effective subsoiling effects, while the detection technology of the subsoiling machine with double inclination sensors installed on the pull rod and plow frame is easy. Affected by the frame degree of the suspension and other links, it is difficult to accurately provide the relative change angle for the calculation of the tillage depth value

In addition, the above devices or methods all have the defect of lacking or not being able to make full use of the judgment of the working state of the subsoiler to assist in the statistics of the effective working area.
