Mixer truck, and adjustment and control method, device and system for feeding position of mixer truck

Abstract

The invention relates to the technical field of mixing machinery, and discloses a mixer truck, and an adjustment and control method, a device and a system for a feeding position of the mixer truck. The method comprises the steps that a current frame image shot by a camera which is positioned outside a feed hopper of the mixer truck and has a shooting direction within a set mounting range is acquired; when the current frame image contains an ellipse target, coordinates of an ellipse center image of the ellipse target are calculated; the ellipse target is a discharge hole image of a mixing station; and when the coordinates of the ellipse center image fall into a set alignment range, the mixer truck is prompted for shutdown. Shutdown prompt information can accurately and timely prompt a driver to shut down, and the accuracy and efficiency of adjustment of the feeding position are improved greatly.

Description

Technical field [0001] The invention relates to the technical field of mixing machinery, in particular to a method, a device and a system for adjusting and controlling the feeding position of a mixing truck and a mixing truck. Background technique [0002] The mixer truck is the power equipment that carries the concrete from the mixing station to the construction site. When the mixer truck feeds from the mixing station, in order to accurately unload the concrete from the mixing station to the mixer truck, it is necessary to ensure that the inlet of the mixer truck and the outlet of the mixing station are accurately docked to avoid waste of materials. [0003] Such as figure 1 As shown, in the prior art, the adjustment of the feed position of the mixer truck usually adopts the following means: a camera 30 is installed near the feed inlet 31 of the mixer truck, and the camera 30 collects relevant images in real time and transmits the images to the cab The driver judges the position ...

AI Technical Summary

Problems solved by technology

[0004] The defect in the prior art is that although the image displayed on the display screen 33 provides the driver with an adjustment reference, how to perform the next step of adjustment operation still needs to rely on the driver's experience and subjective judgment, which makes the feeding position of the mixer truck The accuracy of adjustment is low, and the adjustment efficiency is also low
