For controlling an agricultural machine system while it works a territory, which a route (R) is created for the machine system, which includes working tracks (FN) along which the machine system is driven while the territory (S) is being worked, and which includes headland tracks (FV), along which the machine system is driven when it travels from one working track (FN) to the next working track (FN) to be driven along. The machine system automatically processes a sequence of headland working steps at the end of one working track (FN) and / or while a subsequent headland track (FV) is being driven along, and / or at the beginning of a subsequent working track (FN). The sequence of headland working steps is updated and carried out dynamically depending on the current position of the machine system and depending on the next working track (FN) to be driven along. A related automatic control system for controlling an agricultural machine system is also provided.

An apparatus and method for automatically controlling the settings of an adjustable crop residue discharge system of an agricultural combine is provided. The apparatus includes a sensor, an actuator, and a controller. The sensor detects a position of a residue deflector and / or a speed of the residue discharge system. The actuator operatively controls the residue deflector to adjustably position the residue deflector. The controller is operatively connected to the sensor and actuator. The controller includes a memory, a speed input device, a position input device, and a mode input device. The controller is configured to store in memory a plurality of positions and speeds of the residue discharge system and automatically adjust the positions and speeds of the residue discharge system upon receiving an input to change to headland mode.

A method and apparatus for automating some of the tasks that heretofore required operator action at headland turns or similar events are provided. The present invention automates operation of lift assist wheels and / or gull wings, such as those found on a stack-fold implement, based on the position of the tractor hitch to which the implement is coupled. An operator may control the position of the implement, such as at a headland turn, by raising and lowering the tractor hitch using a remote control. The invention enables the planter to compare the tractor hitch position relative to an implement position and control operation of the implement accordingly without additional user inputs.

The invention discloses a method and device for generating an all-region-covering optimal working path for a farmland plot. The method comprises the following steps of: forming headland turning modes such as a semicircular turning mode, a pear-shaped turning mode, a fish-tail-shaped turning mode and the like by considering the working requirements of tractor units of different types and scales in consistence with the practical requirement of agricultural machinery operating management; putting forward a plurality of working path optimization standards of the tractor units to realize optimization targets such as minimum turning, lowest turning working consumption, a shortest working path, an optimal effective working path ratio and the like; establishing an optimal working direction search method and a working path generating algorithm of the tractor units on the basis of priori information such as a working plot vector, a working unit parameter, a path optimization target and the like to realize all-region-covering of the farmland plot; and integrating embedded hardware devices of functional modules such as a storage module, an input module, an output module, auxiliary equipment and the like to realize planning, calculating, displaying and introducing of the all-region-covering optimal working path for the farmland plot and recording, storing and displaying the practical working path of each tractor unit.

A system has an algorithm for organizing the actions of agricultural machines and servicing vehicles in a field. The algorithm divides the field into logical chunks of work, including at least one swath within at least one headland and within at least one land, which it then assigns to the agricultural machines in order. Priority is first given to working the headlands, then to working swaths within lands where an agricultural machine can perform its function while remaining accessible to the servicing vehicles. When the agricultural machine is in an area where it is not accessible to a servicing vehicle and needs service, the agricultural machine creates an impromptu servicing area. This may be an area within a swath that the agricultural machine has cleared of crops in order to provide the servicing vehicle, such as a haul vehicle or grain cart, access to the agricultural machine and space to turn around.

The invention provides a low-energy coastal beach restoration design method, including constructing the outer edge line of the beach shoulder, determining the aspect ratio of the outer edge line of the beach shoulder, determining the slope of the beach surface and performing sand replenishment, dredging area and dredging depth The determination and the steps of building the sand barrier. The present invention utilizes the characteristics of wave convergence at the headland, constructs a protruding headland-shaped beach shoulder outer edge line by artificial means, and determines the required beach surface range and slope according to the convex beach shoulder outer edge line and proceeds Replenishing sand; dredging around the beach during beach restoration, while reducing mud sources and increasing near-shore water depth, a convex near-shore terrain is constructed, which effectively increases the wave energy at the repaired location and improves the Situation of beach silt on low energy coast.

A tractor head land management control system and a control method thereof are disclosed. The control system comprises a record button, a playback button, an A sequence, a B sequence, a seat switch, a head land management indicating lamp, a main sequence processing unit, a CAN bus, a subsequence processing unit and a controller. The main sequence processing unit and the subsequence processing unit are connected and are integrated in the controller. The two units are connected through the CAN bus. The record button, the playback button, the A sequence, the B sequence, the seat switch and the head land management indicating lamp are connected to the controller respectively. The head land management system is designed compactly and operation is convenient. Record and playback of individual functions can be performed and record and playback of a plurality of functions can be performed too. During a playback process, hand-operated interaction operation can be performed. The control method is convenient to operate. Work efficiency and work quality of a tractor are effectively increased, labor intensity of a driver is mitigated and the tractor is guaranteed to possess a good usage state under various kinds of work conditions.
