大蒜种植机械蒜瓣方向识别算法与控制系统设计

Algorithm and Control System Design on Garlic Direction Identification of Garlic Planting Machine

依据小波算法理论和PLC控制技术,设计了大蒜蒜瓣方向的自动图像采集算法,并在PLC控制过程中设置了PID控制器,开发出了一种新的大蒜种植机械蒜瓣方向识别的PLC控制系统。该系统的硬件系统采用西门子S7-300系列产品,并利用Step7进行软件编程控制。为了验证该系统的有效性和可靠性,选择了158瓣形状规则和不规则的蒜瓣进行方向调整测试。通过测试发现,该系统对形状不规则和蒜尾被遮住的蒜瓣图像也能进行自动化调整,且蒜瓣方向调整准确率都在90%以上,可以满足大蒜自动化种植的需要,为大蒜种植技术的研究提供了一种新的自动化控制方法。

Based on wavelet theory and PLC control technology , this paper designed automatic image acquisition algo-rithm ,and set PID controller settings in PLC control process , developed a new PLC control system of garlic direction iden-tification of garlic planting machine .Using Siemens S7-300 series products as hardware system , it used Step7 to pro-gram and control the system .In order to verify the validity and reliability of the system , it chose 158 petal regular and ir-regular shape garlic to research on direction adjustment and test .The test showed that the system can also automatically adjust irregular shape and garlic clove tail with obscured image , and the garlic direction adjustment accuracy is above 90% by the test results .It can meet the need of garlic planting automation , and provides a new automatic control method for the study of garlic planting technology .
