Problems solved by technology

The horizontal measurement accuracy of the low-precision GPS receiving module can meet the requirements, but the error is large when measuring the elevation coordinates; the cost of the high-precision GPS receiving module is very high, so most of them choose reasonable price, high precision, support RTK (Real Time Kinematic, real-time dynamic measurement) technology dual-frequency GPS-OEM board (RTK GPS-OEM board) to complete the collection of measuring point information

Abstract

The invention discloses an elevation control method based on a global position system (GPS) and a laser technology, which is used for ditching and pipe-laying machine performing ditching and pipe-laying operations and is characterized by comprising the following steps: step 100, arranging a GPS base station and determining position coordinates of a laser emitter and three-dimensional coordinates of a laser receiver fixed on a ditching arm; step 200, judging whether a GPS signal and a laser signal are valid or not and performing corresponding data storage and positioning information processing; step 300, calculating three-dimensional coordinates of the bottom end of the ditching arm in a space coordinate system and driving the ditching arm to move; and step 400, comparing a current ditching arm elevation signal with a preset ditching arm elevation signal to confirm elevation control information and achieving control of deep adjustment of a hydraulic cylinder.

Description

technical field [0001] The present invention is aimed at the technical field of automatic control of agricultural machinery and equipment, and relates to a method and system for elevation control, in particular to a method and system for field operations of ditching and pipe-laying machines using GPS (Global Position System, Global Positioning System) technology combined with laser technology. A method and system for real-time control of ditch depth and slope. Background technique [0002] Before the 1990s, the elevation (ditching depth and slope) of the trenching pipelayer has been measured manually and controlled by mechanical devices, which is not only labor-intensive, but also low in efficiency, and it is difficult to avoid some human errors. affect the construction quality. Since the 1990s, with the development and progress of agricultural machinery automation, the elevation control of trenching and pipelayers is generally completed by laser guidance devices. The bas...
