【摘要】：土壤比贯入阻力是反映耕地土壤板结程度的一项重要指标。现有测量装置多采用人工手动加载测量的方式,无法依据测量标准保持恒速,准确度、自动化程度及测量效率低,且劳动强度大。为此,应用传感器技术、机械电子技术、无线通信技术,以及智能终端设备设计研制了一种基于Android手机WIFI控制的电动式土壤比贯入阻力测量装置。该装置以单片机传感器为核心,采用电机驱动实现圆锥测头按ASAE S313.3 FEB04标准以3 0.4 8 mm/s恒速贯入土壤,测量数据实时显示并存储于TF卡中;初步设计实现了使用Android手机,通过WIFI通讯与测量装置建立连接、操控测量装置,接收、存储测量数据,并绘制曲线。测试结果表明:该装置结构简单、测量精度高、操作简单、自动化程度高,应用前景广阔。
[Abstract]:Soil specific penetration resistance is an important index to reflect the degree of soil consolidation in cultivated land. Most of the existing measuring devices adopt manual loading and measuring method, which can not keep constant speed, accuracy, automation and measuring efficiency according to the standard of measurement, and the labor intensity is large. In this paper, an electric soil penetration resistance measuring device based on Android mobile phone WiFi control is designed and developed by using sensor technology, mechanical and electronic technology, wireless communication technology and intelligent terminal equipment. The device uses single chip microcomputer sensor as the core, uses the motor to drive the cone probe into the soil according to ASAE S313.3 FEB04 standard at a constant speed of 30.48 mm/s, and displays and stores the measured data in TF card in real time. The preliminary design realizes the use of Android mobile phone. Through WiFi communication and measurement device to establish the connection, control the measuring device, receive, store the measurement data, and draw the curve. The test results show that the device has the advantages of simple structure, high measuring precision, simple operation, high automation and wide application prospect.
