The “unmanned farm” technology is full of style

“What is operating in this field is a driverless Combine harvester. It is completely unmanned and operates independently in and out of the warehouse. What is parked next to it is a special transfer vehicle, which can realize independent grain unloading and support one button grain unloading…” On the morning of June 8, at the integrated demonstration base of rice wheat rotation “unmanned farm” in Chengqiao Street, Luhe District, Nanjing, agricultural experts were explaining the situation of on-site unmanned operation. Jiangsu Agricultural Machinery Promotion Station More than 80 people, including Jiangsu Agricultural Machinery Test and Appraisal Station, Nanjing Municipal Bureau of Agriculture and Rural Affairs, Nanjing Agricultural University, and principals of unmanned farm construction in each district, watched the demonstration.

The construction project of the “unmanned farm” integrated demonstration base for rice wheat rotation is a major agricultural technology equipment integration demonstration project in Jiangsu Province, covering an area of 520 acres. At the scene, 8 sets of unmanned agricultural machines and tools, including unmanned harvesters for grain transportation, real-time intelligent yield measurement unmanned harvesters, unmanned tractors, unmanned high clearance plant protection machines, unmanned Rice transplanter, variable rate fertilizer spraying agricultural unmanned aerial vehicles, and other intelligent agricultural management platforms, such as “unmanned farm” digital base and “unmanned farm” information management platform, appeared for demonstration. Experts provided detailed explanations on relevant equipment and technology.

The reporter saw that the on-site demonstration of unmanned harvester collaborative grain transportation equipment can achieve autonomous path planning, cooperate with specific transfer vehicles to achieve autonomous grain unloading, support one click grain unloading, and achieve unmanned grain harvesting and transportation throughout the entire process; The real-time intelligent yield measurement driverless harvester is equipped with yield monitoring sensors to realize real-time monitoring and data transmission of yield, moisture and other information during unmanned harvesting operations, and generate the spatial distribution map of crop yield in real time online. The relevant data can also be used to optimize the production management of Precision agriculture for quantitative decisions such as planting, fertilization and spraying in the next season; Variable fertilizer spraying agricultural UAV, based on the real-time seedling growth information provided by the remote sensing monitoring of rice growth, uses the rice diagnosis and regulation model system to quantitatively recommend the precise amount of nitrogen fertilizer and pesticide, and generates the “prescription map” of fertilizer and pesticide application in different fields of the base, so that the base growers can accurately obtain the amount of rice topdressing and pesticide application in different fields, and realize the Automatic variable precise fertilizer spraying based on UAV.

The “Unmanned Farm” digital base, based on a large-scale digital map, has constructed a smart farm data base that includes farm fields, farm facilities (roads, ditches, pumping stations, warehouses, etc.), soil, meteorology, varieties, management measures, crop growth, etc., fully supporting the operation of the smart farm digital drone operation system. Through the information management platform, real-time updates are achieved on the planting, environment, fields, agricultural machinery, and irrigation overview of the “unmanned farm”. Remote real-time monitoring of field conditions is carried out, and remote sensing technology is used to monitor the growth, yield, and diagnosis of crops in different plots. Accurate fertilization and irrigation prescriptions are generated, and disasters are analyzed and crop yields are predicted.

The relevant person in charge introduced that the farm has equipped 8 sets of “unmanned” agricultural equipment for the four key links of rice and wheat rotation cultivation, management and harvest; We have achieved the construction goals of “unmanned farms”, including unmanned, precise operations, visualized information management, and intelligent analysis and decision-making.
