A seed sensor senses seeds on a row unit and generates a seed sensor signal. A number of planting characteristics, such as a seed orientation, seed slugging, delivery system wear, and seed abnormalities, can be detected based on the seed sensor signal. The planter can be controlled based on the detected planting characteristics.

Planting characteristic detection and control using a seed sensor

A seeding machine () includes a seeding mechanism () driven by a seeding motor (). A motor command signal is compensated for accelerations based on a wheel based speed of a towing vehicle ().

Acceleration compensation in controlling a seeding machine

An agricultural machine includes a material distribution system and a sensing system including a first sensor configured to generate an indication of a first measure of a first flow of agricultural material in a first material distribution line, a second sensor configured to generate an indication of a second measure of the first flow of the agricultural material in the first material distribution line, and a third sensor configured to generate an indication of a measure of a second flow of the agricultural material in a second material distribution line. A control system is configured to detect occurrence of an anomalous operating condition based on the measure of the second flow and at least one of the first measure of the first flow or the second measure of the first flow of the agricultural material.

Agricultural material distribution anomaly detection and control system

A row unit for a seeding machine includes a ground view sensor coupled to the frame. The ground view sensor is operable to sense the furrow and generate depth signals corresponding to actual sensed depth of the furrow. The row unit also includes a controller configured to receive the signals, and a downforce adjustment mechanism coupled to the frame and to the controller. The controller is configured to activate the downforce adjustment mechanism to adjust a downforce on the frame based on the signals received by the controller.

A plurality of different controllers on an agricultural machine are time synchronized. A first controller, identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, and generates a timestamp indicating a time at which the action is to be taken. An action identifier and the timestamp are sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the timestamp based upon the actuator delay.

Planter control using timestamp/location stamps

An agricultural machine includes a metering system comprising one or more meters configured to meter particulate material into a first material distribution line and a second material distribution line, a first sensor configured to generate a first sensor signal indicative of a first measure of a flow of the particulate material in the first material distribution line, a second sensor configured to generate a second sensor signal indicative of a second measure of the flow of the particulate material in the first material distribution line, and a control system. The control system is configured to receive an indication of a sensed flow rate of the particulate material in the second material distribution line, obtain an adjusted flow rate indication by applying, to the sensed flow rate, a rate offset based on the first and second sensor signals, and control the metering system based on the adjusted flow rate indication.

Agricultural seed sensing and control system

A plurality of different controllers on an agricultural machine are time synchronized. A positioning system detects a geographic location and a timestamp, which is indicative of a time when the geographic location was sensed, is applied to the geographic location. A first controller, that identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, generates a future timestamp indicating a future time at which the action is to be taken. An action identifier (that identifies the action) and the future timestamp is sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the future timestamp based upon the future timestamp, a current time, and the actuator delay.

An example agricultural machine comprises a material distribution system that includes a material distribution line configured to convey particulate material to a component. The agricultural machine comprises a sensing system that includes a first sensor configured to generate a first sensor signal indicative of a measure of a flow of the particulate material in the material distribution line, a second sensor configured to generate a second sensor signal indicative of a measure of the flow of the particulate material in the material distribution line, and a correlation generation component configured to receive indications of the first and second sensor signals and to generate a correlation metric that represents a correlation between the first and second sensor signals. In one example, the correlation metric is applied to a sensor signal from a second material distribution line to determine a flow rate in the second material distribution line.

A seeding apparatus and a method is disclosed in which a seed spacing variability value is determined and displayed to the operator during a planting operation. Any method of determining variability among a set of data can be used to determine the seed spacing variability value. Three examples are shown: standard deviation; coefficient of variation; and coefficient of uniformity. Data can be stored for later comparison with harvest yield data to determine the effects of seed spacing on yield.

Seeding apparatus and method of determining a seed spacing variability value

A seeding machine includes a main frame, and a row unit coupled to the main frame. The row unit has a row unit frame, a gauge wheel coupled to the row unit frame, and a furrow opener coupled to the row unit frame, the furrow opener having a stationary or rotating surface that contacts and moves soil. The row unit also includes a furrow closer, the furrow closer having a stationary or rotating surface that contacts and presses soil. The seeding machine also includes a downforce adjustment system for adjusting an amount of downforce applied to the row unit, the downforce adjustment system including a moisture sensor, a controller configured to receive a signal from the moisture sensor, and an actuator configured to change the amount of downforce applied to the row unit based on the signal received by the controller.

Soil moisture-based planter downforce control

Sensor information is received from a set of sensors. First and second sets of machine monitoring data are generated from the sensor information. The first set of machine monitoring data is sent to a control system with a display in an operator compartment of a mobile machine. The second set of machine monitoring data is sent to a processing system that is separate from the control system.
