Digitalized paddy rice seed testing machine

Abstract

The invention relates to an online non-destructive testing method which is suitable for automatically measuring and recording the total grain number, the filled grain number, the maturing rate, the grain lengths, the grain widths and the length-width ratio of a single plant or single-batch paddy rice in the paddy rice seed testing process for agricultural scientific research personnel. The digitalized paddy rice seed testing machine mainly comprises six functional modules of a bar code recognizer, a grain transfer device, an air separation device, an image acquisition device, a PLC (Programmable Logic Controller) and a computer system. The digitalized paddy rice seed testing machine can be used for separating filled grains and empty and shriveled grains by utilizing the air separation device, dynamically acquiring grain parameters by utilizing a machine vision technology and simultaneously measuring the total grain number and the filled grain number of the paddy rice, thereby overcoming a bottleneck that the traditional testing measure can not simultaneously acquire the total grain number and the filled grain number and realizing the detection to the grain-size parameters of the paddy rice at the same time of calculating the paddy rice grain number. The invention can be also widely applied to the seed testing work of other grain crops.

Description

technical field [0001] The invention relates to an on-line system suitable for agricultural scientific researchers to automatically measure and record the total grain number, solid grain number, seed setting rate, grain length, grain width and aspect ratio of a single plant or a single batch of rice during the rice plant testing process. The non-destructive testing method specifically refers to a digital rice seed testing machine that uses a winnowing device to separate solid grains and empty grains, and uses machine vision technology to dynamically obtain grain parameters. Background technique [0002] The test and investigation of rice varieties is a necessary step in the experiment, demonstration, popularization and high-yield cultivation of rice varieties. Total grain number, solid grain number, seed setting rate, grain length, grain width and aspect ratio are several key parameters in rice breeding test. Among them, the total number of grains, the number of solid grain...
