Abstract
PURPOSE: To provide an obstacle detecting system, in which a marker is placed a predetermined distance ahead of an object that is proved not o be an obstacle, such that objects standing within a predetermined distance from the markey may not be misunderstood as obstacle.
CONSTITUTION: In a system, comprising radar means 6, signal processing circuit 7, AND-circuit 8, alarm 9, etc., which detects the distance between object 4 and vehicle 2 on travelling crane 1 to judge from the output signal whether the object 4 is obstacle or not, and if it is judged that the object 4 is an obstacle, alarm signal is produced; there are further provided a marker 5 placed a predetermined distance ahead of non-obstacle object 4, a marker sensor 10 for detecting that vehicle 2 has reached the marker 5, a circuit including down-counter 13 or the like for detecting the distance between the object 4 and vehicle 2 from said output signal, and an equality detecting cirucit 18 for interrupting said alarm signal when the signal of said circuit becomes equal to the signal of relative distance
