Transversal distribution of a spray drone applying different nozzles and measuring methods

Abreviations: One single measurement (flight of the drone on patternator, Water Sensitive paper or filter paper have been indicated as follows: Example “XR-1-P”: Nozzle – Repetition - Measuring Method Nozzle: 3 types of nozzles have been used XR, TXA, IDK Repetition: 1-3 Measuring method: patternator – water sensitive paper – filter paper So XR-1-P is the measurement with the XR nozzle, first repetition on patternator Distance cm: The distance indicates the length of the patternator, the water sensitive paper and the filter paper which ware all 600 cm. The single measuring length of the different methods were different. Patternator had 10 cm wide grooves, filter paper strips were 25 cm long and water sensitive paper strips were 20 cm long. Measuring methods Patternator used with 10 cm measuring width per cylinder. Milliliters “ml” of liquid per cylinder are measured. Water Sensitive Paper: Coverage 1 = 100 % has been measured using image anlysis, 20 cm strips have been analysed Filter: Deposits on filter paper have been measured, recovery of the product (product/m2) is indicated in percents. Standardisation of data to 20 cm units Patternator: To standardise the original measuring length of 10 cm to 20 cm two measuring grooves of 10 cm just have been added. Water sensitive paper: the original values of the 20 cm strips have been used Filter paper: New values (20 cm length) are calculated out of old values (25 cm length) attributing them the linear weight of the different length of the included measurements Value for 20 cm = value of original 25 cm value (FP25) Value for 40 cm = (FP25 * 5/20+FP50*15/20) (“5 cm of FP25 and 15 cm of FP50” are taken) Value for 60 cm =(FP50*10/20+FP75*10/20) (“10 cm of FP50 and 10 cm of FP75” are taken) Value for 80 cm =(FP75*15/20+FP100*5/20) (“15 cm of FP75 and 5 cm of FP100” are taken) Value for 100 cm = FP100 and so on Data standardised, Max. = 100 % The maximum of each measurement was linearly standardised to 100 % to be able to compare the relative distributions of the different measurements. Shift of the curves: The curves were manually adjusted to have the maximum at 300 cm.缩写说明： 单次测试（采用喷幅测试仪（patternator）、水敏试纸（Water Sensitive Paper）或滤纸（filter paper）开展的无人机飞行施药测试）的命名规则如下： 示例“XR-1-P”代表：喷头（nozzle）型号-重复次数-测试方法 喷头型号：本次测试共使用3种喷头，分别为XR、TXA与IDK 重复次数：共1至3次重复测试 测试方法类别：喷幅测试仪法、水敏试纸法与滤纸法 因此“XR-1-P”代表采用XR喷头、第1次重复的喷幅测试仪法测试数据。 测试距离（单位：厘米）：本次测试中，喷幅测试仪、水敏试纸与滤纸的总布设长度均为600厘米，但不同测试方法的单段测量长度存在差异：喷幅测试仪的单段测量凹槽宽度为10厘米，滤纸测试条单段长度为25厘米，水敏试纸测试条单段长度为20厘米。 测试方法细则： 喷幅测试仪法：以每段10厘米为测量单元，采集每段对应的液体体积，单位为毫升（ml）。 水敏试纸法：通过图像分析法（image analysis）测定药剂覆盖度，其中覆盖度等级1对应100%全覆盖，本次测试采用20厘米长的试纸条进行分析。 滤纸法：测定滤纸上的药剂沉积量，以百分比形式表示药剂回收率（单位：药剂/平方米，即product/m²）。 数据标准化（统一至20厘米测量单元）： 喷幅测试仪法：将原10厘米的单段测量长度标准化为20厘米，通过叠加两段相邻的10厘米测量凹槽数据实现。 水敏试纸法：直接采用20厘米试纸条的原始测量值，无需额外折算。 滤纸法：将原25厘米长度的测量值折算为20厘米长度的新值，折算依据为各测量段长度对应的线性权重。具体折算规则如下： - 20厘米长度对应值 = 原25厘米测量值（FP25） - 40厘米长度对应值 = (FP25 × 5/20 + FP50 × 15/20)（即取5厘米FP25与15厘米FP50的数据进行加权计算） - 60厘米长度对应值 = (FP50 × 10/20 + FP75 × 10/20)（即取10厘米FP50与10厘米FP75的数据进行加权计算） - 80厘米长度对应值 = (FP75 × 15/20 + FP100 × 5/20)（即取15厘米FP75与5厘米FP100的数据进行加权计算） - 100厘米长度对应值 = FP100 - 以此类推 数据标准化后最大值设为100%：为便于对比不同测试的相对分布特征，将每次测试的最大值通过线性归一化处理至100%。 曲线偏移处理：通过手动调整将所有测试曲线的峰值位置统一至300厘米处。
