Ground and air agrotechnological units with contactless power supply and control

The article describes the possibilities and methods of managing large agricultural business production, the technological processes carried out in large areas. An analysis of the trends in the development of such agricultural complexes indicates the prospects for the use of wirelessly connected mobile units and systems (WUS) ground and airborn, including unmanned ones. The functioning of the WUS in the conditions of agricultural production has a number of features: large territories and their remoteness, instability of operating conditions: continuous transformations of the characteristics of the external environment, parameters of technological processes, the state of a self-organizing object of agricultural production, the associated emergence of new tasks, correction of the implemented operations, trajectories of the object's movement, etc. These features necessitate the use of special devices to support technological readiness, efficient power supply and maintenance of the WUS, and adaptive process control. The costs and terms of putting these services into operation can be significantly reduced by using the infrastructure of facilities for various purposes located in the territories where the WUS operate: centralized power supply lines, mobile telecom operators, territorial control and management centers, etc. In the future, this approach will reduce the cost of maintenance and operation of WUS, their power supply systems and generally lower the cost of implementing agricultural processes. Specially equipped platforms are supposedto locate bases for the deployment of wirelessly connected technological units with systems for recharging the batteries of these units, while masts and supports are supposed to have systems for recharging units of air functioning. Based on the requirements of efficiency, energy saving and automation of WUS technological processes, the use of electrified units with contactless power supply when moving in the working area is promising. The application of a contactless electric charging system using a single-conductor resonant power transmission system is considered.
