METHOD OF CONTROLLING REMOTELY LOCATED FARMING MACHINERY AND DEVICE THEREOF

摘要

PURPOSE: A method of controlling a remotely located framing machine with a hybrid positioning system combining a global positioning system(GPS) and a dead-reckoning(DR) and the device thereof are provided to position a remotely located farming machine and ,using the data of the machine's position and operation, order the machine specific operations remotely. CONSTITUTION: In a controller remotely controlling a farming machine, a step(S100) turns on the controller. (S110) initializes the variable storing the location of the machine. (S120) provides a certain delay time to stabilize a GPS sensor, a zyro sensor and a speed sensor after these sensors are turned on. (S130) gathers the data of location, azimuth angle and speed detected by these sensors respectively. (S140) analyzes the location data from the GPS sensor and verifies if the location information calculated with the data of angle and speed comes within an allowable error range. (S150) compensates the azimuth angle data of the zyro sensor with the azimuth angle calculated with the data by the GPS sensor. (S160) renews the location of the machine with the current data by the GPS sensor. (S170) analyzes the movement information consisting of the speed sensed by the speed sensor, the direction by the zyro sensor and the trajectory by the GDS sensor. (S180) sends the analyzed result to the control center through the controller or wireless transmitting device of the machine. (190) checks if there is more operation to do. (S190) ends the entire operation.
