The invention discloses a ground transport
vehicle control device and a control method thereof. An upper and lower integrated
control system is formed by an upper computer and an AGV
system. Optimal task allocation and cooperative allocation of a plurality of AGVs forming the AGV
system can be obtained through an upper computer running program, and
butt joint can be accomplished through a plurality of ultrasonic receiving systems in an ultrasonic automatic following, receiving and
positioning system to completely cover the whole
control area, so that errors caused by wave losing and restrictions of a blind area can be avoided, the positioning range of each ultrasonic receiving
system is enabled to be wider, the number of the ultrasonic receiving systems is reduced, the cost is reduced, thepositioning data is more accurate, and the reliability is high; a vehicle-mounted display screen can display the located position, the speed and local obstacle information in real time; meanwhile, anobstacle avoidance system is adopted, static and dynamic obstacles within different ranges can be avoided in a fast response and accurate distance manner, and the
fault tolerance rate is improved; and the overall system is stable in performance, a problem that the traditional ultrasonic
positioning system is too large in blind area is solved, and the operation cost and the maintenance cost are low.
