Agricultural machinery opens the era of "no one"

The unmanned tractor entered the field

On April 24, a large tractor is working on the land west of Chengezhuang Village, Henan Zhai Town, Miyun County, Beijing. Unlike ordinary tractors, the driver in the cab does not have to operate manually when sitting in his seat, and the tractor ploughs automatically in the field, which attracts farmers who stand at the edge of the field to marvel: "for most of my life, it's the first time I've seen a tractor that doesn't need a human driver. It's amazing!"

From the outside, the tractor equipped with the automatic navigation and driving system of Beidou agricultural machinery is no different from an ordinary tractor except for the white GNSS antenna on the top, but there is a clear view of the tractor operation and the environment of the fields in the tractor driving room with a touch LCD display screen. After setting the parameters before the operation, the navigation system guides the agricultural machinery into the automatic operation mode and starts straight-line farming. "after positioning, you basically don't need the steering wheel when walking in a straight line, as long as you adjust the working direction of the tractor when you turn the ground, which is very convenient and easy to operate. The walk is also very straight, much more accurate than manual operation, and can still work at night. " The introduction of the operator said.

During this year's spring ploughing, unmanned tractors and seeders navigated by the global satellite positioning system have been put into field operations on some large farms in Xinjiang and Northeast China, greatly improving the quality and efficiency of farming operations and effectively reducing the input of agricultural production costs. Unmanned agricultural machinery is becoming a new bright spot after drones, and agricultural machinery is ushering in the "unmanned" era.

Self-driving agricultural machinery has many advantages.

Unmanned agricultural machinery uses satellite positioning and navigation system to remotely direct automatic driving of agricultural machinery for precision tillage. this system perfectly combines satellite navigation, automatic control technology and agricultural machinery. the working principle is that the satellite positioning signal is transmitted to the tractor through the second accurate positioning through the self-contained base station. Before farming, technicians input the cultivated area, soil thickness and other parameters into the navigation system. After the antenna receives the signal, it can realize automatic straight-line driving through the navigation system. In addition to tractors, seeders, harvesters, plant protection machines and other large agricultural machinery can apply satellite navigation autopilot system.

According to reports, the main advantage of unmanned agricultural machinery is that it can work 24 hours a day, and its labor efficiency is 2 to 3 times higher than that of manual driving. traditional agricultural machinery can only work 80 mu a day, while unmanned agricultural machinery can work 160 mu during the day and night, thus improving the use efficiency of agricultural machinery. Self-driving not only greatly reduces the labor intensity of the driver, but also the working quality is higher than that of manual driving, with a deviation of less than 2 cm per kilometer, which significantly improves the operation accuracy and reduces the waste of land caused by improper operation of the driver. avoiding repeated operations can maximize the utilization rate of land, seeds and chemical fertilizers, reduce production costs and increase the ratio of input to output. At the same time, the automatic driving system is used for ridging or sowing in farmland, and the plant spacing of crops is uniform, which is conducive to crop growth, ventilation and the absorption of water and nutrients, and can provide the best growth space for crops. it is beneficial to increase the yield of crops and the machine harvest in autumn. Today, with the shortage of agricultural labor and higher and higher requirements for the efficiency of agricultural machinery, unmanned agricultural machinery undoubtedly has many advantages and good market potential.

Domestic unmanned tractors have been put on the market.

At present, some large domestic agricultural machinery enterprises have launched tractors equipped with automatic navigation driving system, and have been listed in batch.

The automatic tractor with agricultural machinery navigation and automatic operation system independently developed by Futian Leiwo heavy Industry is applied to spring ploughing operation in Xinjiang for the first time this year. The automatic tractor integrates many automatic functions such as global satellite positioning and GPS automatic navigation, the tracking accuracy of linear navigation is less than 5 cm, and the automatic alignment accuracy is less than 10 cm. It realizes the tractor to automatically control cultivated land, precision sowing, fertilization and other operations, and solves the bottleneck restriction of "non-straight sowing and incorrect connection". At the same time, the tractor with automatic navigation system is not limited by light, and can achieve continuous operation at night, especially in large plots, not only the land utilization rate is improved, but also the owner's income can be increased by 20%. This product has been put on the market in large quantities and is very popular in the market.

John Deere's ATU automatic navigation system has been widely concerned by users all over the country since it was introduced into the Chinese market. Following the delivery of the first batch of ATU automatic navigation equipment in Guangxi in March, John Deere held a demonstration of ATU automatic navigation in many places across the country in April, and the John Deere tractor equipped with ATU automatic navigation system demonstrated deep loosening, sowing and other operations. It is understood that John Deere ATU automatic navigation system RTK signal accuracy can reach 2.5cm, SF2 signal accuracy can reach 5cm, can be competent for accurate sowing, ridging, spraying, harvest and other operations.

As a leading product of Zoomlion heavy Science "Intelligent Agricultural Machinery", the "King of farming" RV1254 tractor is equipped with terminal information control systems such as autopilot and 3D touch navigation, and is equipped with a domestic Beidou satellite navigation autopilot system, which can realize the tractor operation with a straight and accurate connection, with a 1000 meter sowing line deviation of no more than 2 cm and 24-hour round-the-clock operation, which effectively improves the operation quality and shortens the operation cycle. The operation accuracy can be greatly improved by setting farmland boundaries and driving paths to avoid repetition and omission of operations, while recording driving paths and measuring farmland area. It has obvious advantages in fine soil preparation, precision sowing, precise plant protection and mechanized harvesting of crops such as sugarcane, cotton, tomato, sugar beet and peanut.

It is also understood that tractors currently in use can also be driverless by installing satellite navigation autopilot systems. Due to the high price of this system, farmers who have installed satellite navigation autopilot systems can receive subsidy funds in some areas of Xinjiang. If they can enter the national subsidy catalogue, unmanned agricultural machines will be used in the field as quickly as drones.
