Description

technical field [0001] The invention relates to the technical field of intelligent devices for greenhouses, in particular to a multifunctional operation platform for greenhouses and a control method thereof. Background technique [0002] The vegetable industry is a labor-intensive industry, and the planting, pruning, fertilization, pesticide application, picking, and transportation of facility vegetable production are inseparable from the participation of human beings. The area and output of facility vegetables in my country continue to expand, and it is expected to reach 62 million mu in 2021. However, behind the continuous development of the industry, there are many problems: ①The agricultural labor force is aging and the structure of employees is unbalanced: Taking Shandong Province as an example, 2010-2018 15 -The proportion of the population aged 64 decreased from 74.4% to 66.9%, and the proportion of the population aged 65 and above increased from 9.9% to 15% (data from...

Problems solved by technology

② Labor costs have increased significantly, and agricultural labor costs have continued to increase. According to surveys, labor costs have become the main cost of facility vegetable operations, accounting for 40% to 60% of total expenditures in vegetable production enterprises, and some are even higher

Domestically, there have been relevant researches on robotic technology research and equipment development for greenhouses: a trackless autonomous mobile platform for greenhouses (patent publication number: CN206156246U) proposes a trackless autonomous mobile platform for greenhouses, which can realize It can move flexibly in the greenhouse and has a lifting function, which can be used for pesticide application, picking, crop arrangement, etc., but its disadvantage is that it needs to build a semi-structured road surface in the greenhouse, which is not conducive to agricultural operations such as plowing in the later stage. Agricultural production has a certain impact

The track-type walking device for intelligent spraying in greenhouses (patent publication number: CN205865353U) provides a track-type walking device for intelligent spraying in greenhouses. Agricultural production, but the disadvantage is that the device has a single function and is only used for spraying, and the height adjustment method is adjusted by adjusting the screw, which is inefficient

A kind of boom system and its suspension self-propelled greenhouse special multifunctional deformation spraying device (patent publication number: CN205389739U) has proposed a kind of spray boom system and its suspension self-propelled greenhouse special multifunctional deformation spraying device, can according to The different morphological structures of the target crops are used to adjust the device to improve the penetration of the spray. The device only builds a row of tracks to save space and cost, but its disadvantage is that it has a single function. Although it mentions multiple functions, it can only be used for spraying ; Its structure determines that the spray can only be sprayed from top to bottom. This spray method has poor penetration to the leaf surface and cannot effectively spray to the bottom of the leaf surface, which affects the spray effect

A kind of greenhouse multifunctional operation vehicle (patent publication number: CN205011337U) provides a kind of multifunctional track operation vehicle with lifting device, its shortcoming is that the track of this device is arranged in the aisle of the greenhouse, which affects agricultural production. Control the operation vehicle to move back and forth and up and down, with low intelligence

An autonomous navigation spraying robot and its control method for orchard operations (patent publication number: CN109892311A) discloses that the control system receives and processes data from satellite positioning devices, inertial navigation devices, etc., to realize the drive control of the robot, Path learning, autonomous navigation, spraying control, remote communication and other functions, but the system can only rely on satellite positioning to achieve positioning. In the greenhouse, the satellite antenna is blocked, and there is no satellite positioning signal in the greenhouse when it is covered, and Locating via satellite is expensive
