大蒜是我国一种重要经济作物，在我国有较大的种植面积。由于大蒜种植时具有鳞芽朝上的农艺要求，因此我国的大蒜种植主要是靠人工，劳动强度大，效率较低。为解决大蒜机械化种植中蒜瓣朝向问题，设计了一种基于PLC 控制技术的蒜瓣方向识别系统，并对其在田间的实用性和准确性进行了试验，以期提高大蒜种植作业的效率和质量。用红外检测装置对蒜瓣的外形性状进行扫描，通过 PLC 对来自红外检测装置的数据进行模糊计算，根据计算的结果判定蒜瓣方向，向机械手发出相应指令。对原型机和改进型所种植的蒜瓣，进行空穴率、双粒率、倒立率、出苗率及产量数据分析，发现两种机械的空穴率、双粒率和出苗率之间没有显著差异，但是改进型种植机产生的倒立率显著低于原型机，说明该蒜瓣方向识别系统能够满足机械种植时蒜头向上种植的要求。%Our garlic is an Important Cash crop in China has a large acreage , with bud scales up agronomic requirements of garlic planting , so our garlic is grown mainly rely on manual , labor-intensive , low efficiency .To solve the mechaniza-tion of planting garlic in the garlic towards problem , we designed a PLC-based control technology garlic direction identifi-cation system , and tested the practicality and accuracy in the field , in order to improve the efficiency and quality of garlic planting operations .Infrared detection means garlic shape traits scan data from the PLC by means of the infrared detector fuzzy calculation , determining the direction of garlic according to results of the calculation , issue the appropriate com-mands to the robot .According to this system , and improved prototype planted garlic , conducted hole rate , double the rate of grain , inverted rate , emergence rate , production data analysis , found that both mechanical hole rate , dual rate and emergence rate of grain no significant difference between , but inverted rate improved planting machines produce sig-nificantly lower than the prototype , so the yield increased significantly , with higher quality planting .Description The gar-lic direction identification system to meet the mechanical planting , planting garlic up requirements .
