Abstract


Abstract: With the rapid development of China’s agricultural modernization, the efficiency of plant protection operations and the scientific use of pesticides and fertilizers have higher requirements.  For crop pest control, agricultural aviation technology has been widely recognized.  However, at this stage, manned helicopter aerial plant protection operation is affected by operating conditions, operating environment and pilot experience, which is not enough to ensure the uniformity and stability of the quality of plant protection operation.  In order to solve this problem, this paper designs a set of manned helicopter trajectory monitoring system for plant protection operation.  With the background of the 2022 summer UCPD agricultural aerial application operation in Jilin Province, a Bell 407 helicopter was used to carry the trajectory monitoring system, and real-time operation data were obtained and statistically analyzed.  At the same time, a large number of field trials were conducted to assess the quality of helicopter plant protection operations.  The experimental results show that the flight path monitoring system can accurately obtain the flight altitude, speed, operation trajectory, and application trajectory of the aircraft during vegetation operations.  The average flight speed of agricultural aerial spraying and plant protection operations in Jilin Province in summer is 140-160 km/h, and the average application efficiency is 65-80 km2/h.  The average flight altitude varies greatly with the operation location.  The manned helicopter plant protection operation trajectory monitoring system designed in this article can provide reference for government regulatory departments and farmers to evaluate the quality of aviation plant protection operations, and has practical significance for rational pesticide spraying and promoting precision agriculture.
