Method and device for controlling material discharge and engineering machine

Abstract

The invention discloses a method and a device for controlling material discharge. The method includes acquiring image information of hoppers; extracting image characteristics of the image information and identifying the hoppers; determining distance information of the hoppers relative to discharge outlets by the aid of the image information; monitoring height information of materials in the hoppers in real time by the aid of the image information and the distance information; generating control instructions for controlling discharge speeds in real time according to change conditions of the height information. The image information at least comprises images which are simultaneously acquired by two image acquisition devices. The device and the method have the advantages that the heights of the materials in the hoppers can be automatically detected, then the discharge speeds are automatically adjusted according to pumping speeds of the hoppers, accordingly, overload or loading waiting phenomena can be prevented, wastage of the materials and fuel can be prevented, and the work efficiency can be improved. The invention further discloses an engineering machine.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a discharge control method, device and construction machinery. Background technique [0002] In the traditional unloading process, unloading is often done manually, which has the following problems and shortcomings: Since the height of the concrete in the hopper of the concrete pumping machine cannot be automatically detected, and when the pumping speed is changed, the construction machine cannot automatically adjust Unloading speed, resulting in a mismatch between the unloading speed and the pumping speed, so over-unloading (concrete overflowing the hopper) or pending unloading (unloading speed cannot keep up with the pumping speed) often occurs, which will cause concrete materials and fuel oil waste, affecting work efficiency. [0003] In addition, construction machinery needs to be manually ordered to stop before unloading, and the position and distance of the concrete p...
