土壤比贯入阻力测试装置研究-基于Android手机WIFI控制
Research on the WIFI Control Soil Penetration Resistance Testing Device-Based on the Android Mobile Phone
摘要
Abstract
Soil specific penetration resistance is an important indicator of the study of soil compaction degree .Existing products most use the manual measuring device .Manual operation can't keep constant speed and have low degree of intel-ligence , low precision , high labor intensity and low artificial measuring efficiency .For this purpose , use sensor technolo-gy,mechanical and electrical technology ,Wireless communication technology and Intelligent terminal equipment .The cor-responding design was developed based on the Android WiFi control of electrodynamic soil penetration resistance tester . Single chip microcomputer is the core of the device .The device driven by the motor let cone probe penetrate into the soil as the constant speed of 30 .48 mm/s ( the standard of ASAE S 313 .3 FEB04 ) , realize the real-time measurement and data storage in the measuring device .Using Android phones with WIFI communications , the preliminary design realizes establishing connection with measuring device , controlling measurement device , receiving saving measurement data and drawing curve .Test results indicate that the device has simple structure , high precision measurement , simple operation , a high degree of automation and a wide application prospect .关键词
