Design of Quality Control System for Fighting Machine Operation Based on Beidou Navigation

Abstract

Abstract In view of the serious waste and pollution of pesticide spraying, this study developed a sprayer flow control system based on the high-precision Beidou satellite navigation system software. The system uses a high-precisbion Beidou satellite navigation system R21 positioning receiver. Acquires the vehicle in real-time through the built-in GNSS board of the vehicle. The speed and position information are analyzed and processed by the vehicle intelligent control terminal, and sent to the flow control system corresponding control commands, so that the flow rate of the spray can be controlled according to the speed of the vehicle to realize the electrification control of the spray operation machine. Based on the field operation requirements of the fight drugs machine, an automatic navigation system path tracking control algorithm is designed to make the system complete the route of the line and curve. The real-time information collection of the work is carried out by using the APP carried by the industrial tablet, and the vehicle inherent parameter information is used to interface with the agricultural information platform through the Internet to realize the online monitoring of the spraying operation parameters. At the variable forward speed, tested in a farmland environment. The test results show that the designed automatic navigation path control system and spray flow control system have good working accuracy values and stable operation, which can meet the requirements of farmland environment spraying operation.
