A self-adaptive measurement and control method and system for a distributed feeding potato seed metering device

Abstract

An adaptive measurement and control method and system for a distributed feeding potato seed metering device, the method includes judging the remaining amount of seed potatoes in a test seed box and obtaining data on the remaining amount of seed potatoes; detecting the distribution of seed potatoes in a screw seed feeder and Obtain the distribution data of seed potatoes; obtain the motion parameter data of the rotating speed of the lifting auger, the rotating speed of the seeding chain and the rotating speed and rotation angle of the screw seed feeder; and optimize the mathematical model based on the parameters of the distributed feeding type potato seeding device, according to the The residual data, seed potato distribution data and motion parameter data send instructions to the industrial computer to automatically adjust the speed of the lifting auger, the speed of the screw seed feeder and the rotation angle to the set working parameter combination. The invention also provides an adaptive measurement and control system for a distributed feeding type potato seed metering device using the above method. The invention improves the automation level of the distributed feeding type potato seed metering device, ensures continuous and stable seed supply and efficient seed metering, and improves seeding efficiency and planting precision.

Description

A self-adaptive measurement and control method and system for a distributed feeding potato seed metering device technical field The present invention relates to agricultural measurement and control technology, particularly a kind of self-adaptive measurement and control method of distributed feeding type potato seed metering device laws and systems. Background technique [0002] The potato is used for both grain and vegetables, is nutritious, and is widely planted. Potato "staple food" policy helps to ensure national food safety, and promote the development of modern agriculture. The potato seeder is a key machine for the development of the potato industry, and its sowing quality is directly It is related to the growth and yield of potato, and the seed metering device plays a crucial role in the quality of potato sowing. At present, the spoon type seed metering device is most widely used, and the seed scoop is connected on the conveyor chain or the conveyor belt thro...

Problems solved by technology

[0003] At present, the spoon-type seed metering device is the most widely used. The seed-taking spoon is connected to the conveyor chain or conveyor belt through the handle of the spoon. It has the advantages of low cost, no damage to the seeds, and adjustable plant spacing. The number of seed potatoes is large, and the compaction between seed potatoes is large, which is not conducive to seed picking; on the contrary, the number of seed potatoes is limited, and the contact opportunities between seed potatoes and seed picking spoons are less, which is also not conducive to seed picking, which is prone to seed leakage and affects Seeding performance
