Electric proportional handle correction method for environment-friendly drilling machine

Abstract

The invention provides an electric proportional handle correction method for an environment-friendly drilling machine. System hardware comprises a proportional handle, a controller and a displayer. The correction method includes the steps of S10, initially electrifying a system; S20, when the proportional handle is at a median signal value MID, presetting a median dead zone value DEAD and a fluctuation value WAVE, and correcting the median signal value MID of the proportional handle; and S30, after the correction of the median signal value MID is completed, when the proportional handle is at a foremost signal value MIN or a last signal value MAX, presetting an offset value DIFF, and respectively correcting the foremost signal value MIN or the last signal value MAX of the proportional handle. The effectiveness of the handle can be automatically judged, the drift of a middle position signal of the handle is automatically tracked, the consistency of handle operation hand feeling is ensured, the minimum value and the maximum value of the handle are simply calibrated, the operation process is simplified, the operation difficulty is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of soil drilling rig equipment, in particular to an electric proportional handle correction method for an environmental protection drilling rig. Background technique [0002] Existing sampling rigs are generally equipped with two proportional handles on the local operation panel to control the left and right crawlers respectively. The proportional handle is generally in the form of single-axis self-resetting analog voltage output. The typical output range is 10-90% of the 5V supply voltage, and the median is 50%. Due to the difference in the performance parameters of the proportional handle, the handle of the same model will have slight differences in the middle, the front and the end (the typical value is ±2% of the supply voltage). For single-axis proportional handles, some models not only output the analog voltage signal of the handle position, but also have switch signals for neutral position and forward / backward...

AI Technical Summary

Problems solved by technology

[0005] (1) It is necessary to manually input parameters on the display, and in order to protect the parameters from being modified by unauthorized personnel, password protection is generally set up, and modification is more troublesome

[0006] (2) There is no automatic tracking and correction function for the handle parameters, and the parameters can only be modified manually
