植保无人机施药沉积飘移监测系统设计与应用

为提升植保无人机施药沉积飘移监测智能化水平，研发植保无人机施药沉积飘移监测系统，该系统机载监测终端实时获取药械状态参数、植保无人机状态参数及位置参数，通过数据处理服务系统将其发送至平台软件，基于作业参数利用沉积飘移预测模型实时监测药液沉积区域及飘移范围。该系统同时具有作业面积计量、飞行轨迹回溯、作业质量空间分析等功能。2015年4月于山东省威海市文登区泽头镇眠虎岭区域对该系统进行性能测试，植保无人机规划靶区作业面积为433 hm²，最终监测作业面积为405 hm²，施药覆盖率为93.5%；施药过程中实时监测沉积区域和飘移范围，受环境侧风影响，药液最大飘移距离可达40 m，系统整体达到预期设计要求。截至目前该系统已在山东、安徽、江苏、云南、河南、浙江、天津等多个省市应用。

Design and application of a monitoring system for spray deposition and drift by plant protection unmanned aerial vehicle (UAV)

In order to improve the intelligent level of monitoring spray deposition and drift by plant protection unmanned aerial vehicle (UAV), a monitoring system for spray deposition and drift was developed. Flight parameters of the plant protection UAV, spraying parameters and coordinate position information obtained by airborne monitoring terminal were sent to the platform software through the data server. Then the spray deposition area and drift zone were predicted in real time based on the operation parameters by the spray deposition and drift model. This system also had the functions of operation area measurement, flight trajectory tracking and operation quality spatial analysis. System performance tests were carried out at the Mianhuling area of Zetou Town, Wendeng District, Weihai City, Shandong Province at April, 2015. The nominal operation area of plant protection UAV was 433 hm², while the final monitoring operation area was 405 hm², with a spraying coverage rate of 93.5%. During the application process, spray deposition area and drift range were monitored in real time. Affected by the environmental crosswind, the maximum spray drift distance reached 40 m. Application practice suggested that the system met the expected design requirements. Until now, this system has been widely applied in Shandong, Anhui, Jiangsu provinces, etc.
