<P>PROBLEM TO BE SOLVED: To give a warning suitably to a person who should make an avoidance movement in the case of having the possibility that a collision occurs in a corridor or the like. <P>SOLUTION: A medical worker is made to carry first radio equipment 1, second radio equipment 2 is attached to a carriage device, and a sensor 3 for detecting an object, a receiver 4 for receiving a radio signal, and a warning device 5 for warning that there is the possibility that a collision occurs are provided at a place where there is the possibility that the collision occurs. In the case that the sensor 3 detects an object in a different direction, the receiver 4 determines that the medical worker approaches when receiving a first radio signal, the receiver determines that the carriage device approaches when receiving a second radio signal, and the receiver determines that a general person approaches when receiving no radio signal. Since the warning device 5 makes a warning to an object having a low priority on the basis of a previously set priority when priorities are different and the warning device 5 makes a warning to both objects when the priorities are same, a warning is made, which suggests to the object having a low priority that there is the possibility of a collision. <P>COPYRIGHT: (C)2012,JPO&INPIT |
