Dragging type unmanned liquid application system based on multi-rotor craft

Abstract

The invention discloses a dragging type unmanned liquid application system based on a multi-rotor craft. The system comprises a mobile workstation and the multi-rotor craft, wherein the mobile workstation is used for transmitting task path information specified by a user in the mobile workstation to the multi-rotor craft, processing and displaying information sent by the multi-rotor craft and providing a power supply for the multi-rotor craft, and pumping application liquid to the multi-rotor craft through a liquid conveying pipe. The multi-rotor craft is used for dragging a power supplying line and the liquid conveying pipe, flying to control liquid application according to the task path information sent by the mobile workstation, and sending the acquired information and state information to the mobile workstation. In the dragging type unmanned liquid application system based on the multi-rotor craft, the mobile workstation drags the multi-rotor craft to complete liquid application operation in a manual or automatic mode according to a planed task. The dragging type unmanned liquid application system based on the multi-rotor craft can safely and reliably conduct the liquid application operation in a large range with high precision at high speed.

Description

technical field [0001] The invention relates to the field of agricultural automation, in particular to a towed unmanned liquid application system based on a multi-rotor aircraft. Background technique [0002] As a large agricultural country, the degree of automation of agriculture and the level of labor efficiency are an important indicator of my country's modernization drive. In the process of agricultural production, liquid application operation (watering, fertilization, and pesticide application) is a labor-intensive task. In the vast rural areas, there are currently two methods: ① purely manual method, in the implementation of joint production contract responsibility After the control, the land of each household is less, and mainly adopts the backpack type manual or electric sprayer; multi-rotor, helicopter, etc.) in two ways. [0003] The advantage of the purely manual method is that the cost of equipment is low, and it is suitable for families with less land. It is ...

AI Technical Summary

Problems solved by technology

However, the biggest problems of this method are high cost, low load capacity, short time in space and difficult operation

In the actual field, in order to ensure the effect of spraying, it is generally required to fly at low altitude and slow speed. In this case, a little carelessness in operation will cause serious accidents and pose a great threat to the safety of people's lives and properties.

Due to these unfavorable factors, liquid application systems based on drones are rarely used in rural areas
