针对开沟作业过程中作业深度、宽度依靠人工监测，存在人工工作量大、实时性低等问题，研制果园开沟深度宽度监测装备。通过设计果园开沟深度宽度监测平台，结合LabVIEW上位机人机交互系统与Arduino单片机下位机数据测量系统，最终完成果园开沟深度宽度监测装备的研制，实现开沟作业过程中开沟宽度、开沟深度、作业时间等参数的实时监测、计算、显示与保存等功能。试验结果表明，开沟深度为25 cm时，装备测量误差最大为3.1 cm；开沟深度为30 cm时，装备测量误差最大为2.7 cm；开沟深度为35 cm时，装备测量误差最大为3.7 cm；开沟宽度的测量误差最大为3.1 cm，能够满足实际应用需求，数据实时性较好，能够满足作业监测需求，为智能化果园开沟作业质量实时监测奠定一定的基础。

Design and experiment of monitoring equipment for orchard ditching depth and width

In the process of ditching operation, the data of working depth and width depends on manual monitoring, which leads to the problems of large manual workload and low real time performance. In order to solve the above problems, this paper has developed an orchard ditching depth and width monitoring equipment. By designing the orchard ditching depth and width monitoring platform, combined with the LabVIEW upper computer human computer interaction system and the Arduino single chip microcomputer lower computer data measurement system, the development of the orchard ditching depth and width monitoring equipment is completed. The monitoring equipment realizes real time monitoring, calculation, display, and storage of parameters such as trench width, trench depth, and operating time during trenching operations. The test results show that when the trenching depth is 25 cm, the maximum equipment measurement error is 3.1 cm; when the trenching depth is 30 cm, the maximum equipment measurement error is 2.7 cm; when the trenching depth is 35 cm, the maximum equipment measurement error is 3.7 cm. The maximum measurement error of the groove width is 3.1 cm. The equipment meets the needs of actual applications.With good real time data, the equipment can meet the needs of operation monitoring and lay a foundation for real time monitoring of the quality of intelligent orchard ditching operations.
