System Background
With the development of satellite navigation systems such as Beidou and GPS, precision agriculture is becoming increasingly popular. In order to improve the efficiency of a series of agricultural production such as sowing, spraying, fertilizing, and harvesting, and to increase land use efficiency, navigation equipment for agricultural production has emerged. The agricultural machinery navigation system is an outstanding product in this field.
System composition
Navigation module, Beidou satellite receiver, user's smartphone.
Working principle
The navigation module is equipped with built-in inertial compass and other modules, which can provide vehicle attitude information. Combined with satellite positioning signals, it can compensate for positioning errors caused by terrain changes and calculate the optimal vehicle positioning information.
The navigation system is equipped with a built-in network server and WiFi hotspot. The built-in network server provides a specialized navigation platform for agricultural applications. WiFi hotspot facilitates wireless connection of smart devices such as mobile phones or tablets to navigation devices. Log in to the agricultural machinery navigation platform through a browser on a smart device, set up job information such as job type, tool width, and plot information. The navigation system calculates the best navigation information based on this information and publishes it through a network server for users to view on the smart device. So as to understand agricultural production.
