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 .
