| 1 | Development of sensor systems for precision agriculture in cotton显示文摘Precision agriculture(PA)is an information-based technology,using detailed information within an agricultural field to optimize production inputs on a spatially variable basis,maximize farm profit,and minimize environmental impact.Information collection and processing plays a very important role in PA.In recent years PA technologies have been gradually adopted in cotton production.Several sensor systems for PA were developed and field-evaluated in cotton,including a plant height measurement system(PHMS),the Mississippi cotton yield monitor(MCYM),and cotton fiber quality mapping.The PHMS used an ultrasonic sensor to scan the plant canopy and determine plant height in real time in situ.A plant height map was generated with the data collected with the PHMS.Cotton plant height showed a close relationship with yield(R2=0.63)and leaf-nitrogen content(R2=0.48).The MCYM was developed for cotton yield mapping.A patented mass-flow sensor technology was employed in the MCYM.The sensor measured optical reflectance of cotton particles passing through the sensor and used the measured reflectance to determine cotton-mass flow rates.Field tests indicated that the MCYM could measure cotton yield with an average error less than 5%,and it was easy to install and maintain.The cotton fiber-quality mapping research involved a wireless cotton module-tracking system(WCMTS)and a cotton fiber quality mapping system(CFQMS).The WCMTS was based on the concept that a cotton fiber-quality map could be generated with spatial information collected by the system during harvesting coupled with fiber quality information available in cotton classing offices.The WCMTS was constructed and tested,and it operated according to design,with module-level fiber-quality maps easily made from the collected data.The CFQMS was designed and fabricated to perform real-time measurement of cotton fiber quality as the cotton is harvested in the field.Test results indicated that the sensor was capable of accurately estimating fiber micronaire in lint cotton(R2=0.99),but estimating fiber quality in seed cotton was more difficult.Cotton fiber quality maps can be used with cotton yield maps for developing field profit maps and optimizing production inputs. | Ruixiu Sui J.Alex Thomasson Yufeng Ge | 2012 | International Journal of Agricultural and Biological Engineering2012，5，4： | 3 |

| 4 | Cotton-harvester-flow simulator for testing cotton yield monitors显示文摘An experimental system was developed to simulate the pneumatic flow arrangement found in picker-type cotton harvesters.The simulation system was designed and constructed for testing a prototype cotton yield monitor developed at Mississippi State University.The simulation system was constructed to approximate the pneumatic cotton flow system of a cotton picker,and was capable of operating with varying cotton flow rates.The simulator was tested with different cotton flow rates,and the relationship between feeder rate and amount of conveyed seed cotton was found to be consistent.Further,the simulator was used to conduct tests with the novel optical cotton yield monitor,which proved accurate at measuring the amount of seed cotton flowing through the simulator.Finally,some differences between laboratory testing and field-testing were noted:seed cotton becomes fluffed and twisted when recycled through the simulator,and seed cotton stored in the laboratory tends to be of lower moisture content than cotton during harvest.These differences should be considered when using a laboratory simulator to test cotton yield monitors. | Ruixiu Sui J.Alex Thomasson S.D.Filip To | 2010 | International Journal of Agricultural and Biological Engineering2010，3，1： | 1 |
