Recently, the driverless tractor, a high-tech machine, has gradually become a popular choice for farmers. Many people are still unsure of what type of product it is or how useful it can be for agriculture. Allian Agric will explain in the below.
The driverless tractor uses positioning system technology. It determines the ground's location using Beidou satellite signals. Images transmitted by the tractor's camera are displayed on a monitor, and operators can guide the tractor from a distance simply by viewing the screen. The tractor's onboard computer stores a digital map of the field and then automatically guides itself through the positioning system until all tasks are completed. The system can accurately determine the tractor's location with a margin of error of less than 3 centimeters. Therefore, the routes followed by the driverless tractor when plowing, spraying pesticides, and harvesting crops do not overlap.
The driverless tractor not only saves fuel but also reduces the amount of fertilizer used. It weighs only 1.5 tons. The heavier the tractor, the more the soil is compacted, and the more difficult it is for crop roots to grow. Therefore, higher-powered tractors are often used to till the soil more deeply, but the weight of higher-powered tractors creates a deeper layer of compacted soil. The lighter driverless tractor breaks this vicious cycle and can increase crop production by approximately 10% compared to before.
The driverless tractor's information and control system includes: an automatic steering system, a complete vehicle control system, a radar and vision measurement system, a remote video transmission system, a monitoring system, and a remote control system, among others. It can perform a complete and detailed scan of the surrounding terrain and crops to calculate the appropriate driving route and work process.
It can implement functions such as automatic route planning and navigation in a given area, automatic direction change, automatic braking, automatic engine speed control, automatic control of agricultural implements, active obstacle avoidance, and remote control. Millimeter-scale radar measurement and binocular camera visual recognition technologies, combined with high-precision Beidou positioning technology, can be applied in driverless driving for tilling, preparing, and protecting crops in fields.
In short, technological development is the key to driverless technology. With the progressive improvement of intelligent on-board systems, agricultural equipment, following passenger vehicles and commercial vehicles, has also launched its self-driving products. These technological products have the potential to further improve the current agricultural structure. Currently, they have been widely promoted and received wide recognition.
