Title:
通信状態制御システム
Document Type and Number:
Japanese Patent JP7003830
Kind Code:
B2
Abstract:
To improve communication performance for acoustic communication between a water station and an underwater vehicle.SOLUTION: The communication state control system includes: a water station including a first acoustic communication device; an underwater movable body 3 including a second acoustic communication device; a first position detecting device for detecting a position of the water station; a second position detection device for detecting a position of the underwater movable body 3; a storage unit 10 for storing information on topography of a water bottom; and an arithmetic device 11. The arithmetic device 11 estimates an impulse response by propagation simulation on the basis of a position of the water station, a position of the underwater movable body 3 and topographic information, and estimates a code error rate of acoustic communication by acoustic communication simulation. When the estimated code error rate is greater than a set criterion, the arithmetic device estimates a position of one or both of the water station and the underwater movable body 3 at which the estimated code error rate is equal to or less than a reference value to instruct one or both of a water station and an underwater movable body corresponding to a target position of movement.SELECTED DRAWING: Figure 1
