DIRECTION CONTROL SYSTEM FOR LOW-SPEED TRAVELING OBJECT

Japanese Patent JPH02183813

A

PURPOSE:To control the direction of a traveling object in real time even with a radio circuit that does not have so much high quality of transmission by correcting the change of a target azimuth caused by the advance of a traveling object at the side of the traveling object in a remote control system for traveling object which is carried out with transmission of the radio data. CONSTITUTION:At the side of a fixed station controller 1, an entire traveling area of a traveling object is divided into meshes and all target azimuths showing the traveling directions of a traveling object are calculated in the form of a table. A coordinate conversion part 4 converts the position information on the object 15 detected by a position detecting part 9 into the XY coordinates to produce the coordinate data. A control part 3 sends the correcting value of the target azimuth obtained when the object 15 shifts by a unit time to a traveling object controller 10 together with the target azimuth. Thus transmitting radio wave is demodulated by a radio MODEM 14 of the controller 10, and a control part 11 corrects the target azimuth for each unit time based on the correction value received together with the present target azimuth before input of the next target azimuth. Thus it is possible to control the object 15 in real time even with a radio circuit that does not have so much high quality of transmission.
