Problems solved by technology

Brokenness rate and trash rate are important indicators to measure the operation quality of grain combine harvesters, but online detection of broken rate and trash rate is still a big problem. detection
At this stage, the detection of broken and impurity in the operation quality of grain combine harvesters generally stays in manual separation detection, which is cumbersome and inefficient

Embodiment 1

[0028] The embodiment of the present invention provides an on-line detection system for crushing impurities in a grain combine harvester, such as figure 1 As shown, the system includes:

[0029] Grain sampling bin 1, installed below the grain combine harvester grain outlet, for collecting the grain harvested by the grain combine harvester;

[0030] The side opening of the grain sampling bin 1 forms a grain sample photographing window 16;

[0031] The camera acquires grain sample images through the grain sample photographing window 16;

[0032] The camera device is communicatively connected to a data processing module 13, and the data processing module 13 is used to receive the image of the grain sample and calculate the breakage rate and impurity content rate. The data processing module 13 can choose an embedded data processing module, and the data processing module 13 realizes data communication with the outside through the CAN bus data connector 9 .

Embodiment 2

[0043] This embodiment provides a method for on-line detection of broken impurities in a grain combine harvester, such as figure 2 As shown, the method includes:

[0044] ① Receive detection instructions, including driver control instructions and camera control instructions.

[0045] ② Acquire grain sample images; according to the driver control command, control the driver to drive the telescopic plate 3 to retract, and the grain sampling bin 1 releases the grain sample, with a delay of 100ms; according to the driver control command, control the driver to drive the telescopic plate 3 to extend, and the grain sampling bin 1 Load grain samples with a delay of 100ms.

[0046]According to the control instructions of the camera device, take pictures of the grain samples and perform image preprocessing; judge whether the captured images meet the requirements (that is, the grains in the grain sampling bin 1 completely cover the shooting window, and the captured pictures are full of...

Abstract

The invention relates to an online detection method and system for broken impurities of a grain combine harvester. The online detection method comprises the steps of obtaining a grain sample image in real time through a camera device, carrying out the real-time calculation and analysis of the grain sample image through a data processing module, and obtaining the real-time broken impurity rate of the grain combine harvester, so that online detection of the operation quality and the broken impurities of the grain combine harvester is achieved, the working efficiency of the harvester is improved, problems existing in the harvesting process can be found in time, the harvesting quality is improved, and the intelligent level of the grain combine harvester can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a method and system for on-line detection of broken impurities in a grain combine harvester. Background technique [0002] Grain combine harvesters are gradually developing in the direction of large-scale, automation, and intelligence, and the operating efficiency of machines and tools is getting higher and higher. Brokenness rate and trash rate are important indicators to measure the operation quality of grain combine harvesters, but online detection of broken rate and trash rate is still a big problem. detection. At this stage, the detection of broken and impurity in the operation quality of grain combine harvesters generally stays in manual separation detection, which is cumbersome and inefficient. Contents of the invention [0003] The purpose of the present invention is to provide a method and system for online detection of broken impurities in grain combi...
