PROBLEM TO BE SOLVED: To provide a collision avoidance device and a collision avoidance system, enabling the risk of collision with a mobile object to be reduced.SOLUTION: A collision avoidance device (1) is provided that comprises: a first information acquiring unit (7) which acquires first information from a first information transmitting device (1) having a function to create and transmit first information including the position, speed, and travel direction of a first mobile object; a second information acquiring unit (9) which acquires second information including the position, speed, and travel direction of a second mobile object; a first mobile object predicting unit (11) which predicts a position Pof the first mobile object at future time T on the basis of the first information; a second mobile object predicting unit (13) which predicts a position Pof the second mobile object at the time T on the basis of the second information; a determining unit (15) which determines whether the position Pand the position Psatisfy the preset conditions; and a signal output unit (17) which when the determining unit determines that the preset conditions are satisfied, outputs a signal specific to the case.SELECTED DRAWING: Figure 2 |
