On-line monitoring system and method for crushing of cereals in grain tank of combine harvester

Abstract

The invention provides an on-line monitoring system for crushing of cereals in a grain tank of a combine harvester. The system comprises a cereal conveying mechanism, an image shooting unit and a processor ARM; the cereal conveying mechanism comprises a roller, an oblique conveying belt and a vibration exciter; the roller is located at a grain tank outlet, the oblique conveying belt is located below the roller, and the vibration exciter is mounted at the bottom of the oblique conveying belt; the image shooting unit is located above the oblique conveying belt in the direction perpendicular to the oblique conveying belt; the image shooting unit comprises a CCD camera, a lens, a light source and a data collection card in sequence; the image shooting unit is used for shooting the cereals periodically and transmitting shot images to the processor ARM; the roller, the CCD camera and the light source are all connected with the processor ARM; the processor ARM is used for controlling the roller, the CCD camera and the light source to be switched on and off and analyzing and processing the shot images transmitted by the image shooting unit. Through the device, the cereals can be monitored on line in real time, operation is easy and convenient, and the accuracy rate is high.

Description

technical field [0001] The invention belongs to the field of an automatic monitoring device for the working performance of a combine harvester, and in particular relates to an online monitoring system and method for grain breaking in a grain tank of a combine harvester, which are used for online monitoring of the grain breaking rate. Background technique [0002] Most of the current research on the monitoring of working parameters and performance of combine harvesters is only for the monitoring or prediction model of a single operating parameter, and there is no feedback control for related components based on the monitored current operating parameter values ​​and the fusion of multiple operating parameters. There are relatively few controlled studies. For the monitoring of the performance of combine harvesters, an important parameter-grain breakage rate is not considered. [0003] When the combine harvester is working, when the gap between the header auger and the bottom p...
