Sonar systems of underwater navigation for divers and underwater BLOCK DIVER

摘要

The invention relates to sonar systems underwater navigation and is designed for precise positioning of divers, moving on a given route, to substantially improve security exceptions disorders vital divers during the work, and under water may be used both in free floating and installation diving on the vehicle. Task whose solution proposed utility model is to increase the accuracy of the coordinates at difficult meteorological conditions, possibility of defining the route of movement and current trajectory divers movement in both absolute and relative coordinate systems, exclusion apparatus floating on the water surface, operation simplification hydroacoustic underwater navigation system. This problem is solved by creating a sonar system underwater navigation for divers, comprising providing the vessel with situated thereon equipment, at least one beacon, sonar priemoizluchatel receiver external of the navigation system, the depth determination device, a timer, a display device, in which further the first sonar administered transceiver located on the support vessel, underwater diver unit which comprises a sounder, Doppler log, at least one biometrich esky sensor, a heading sensor, heel, trim, the second receiver external navigation system, a second sonar transceiver device determining the depth, timer, calculation unit performs calculation of the current coordinates from data obtained from sonar, Doppler-lag rate sensor roll , trim, external navigation system receiver, the display device configured to display the current trajectory and predetermined movement route, at least one diver between OJEC echivayuschim ship by a diver and the object of the search, and beacons are designed as responder beacon disposed on divers, sonar priemoizluchatel located on the support vessel and is arranged to request and receive information from the beacon transponders, wherein the computing unit input coupled to the outputs of sonar, Doppler-lag, a biometric sensor, a heading sensor, heel, trim, outer second receiver of the navigation system, the depth determination device, a timer, one of the outputs of the computing unit is connected to second sonar transceiver, and a second output connected to a display device. In addition, the vessel is surfaced hydroacoustic communication station, and is located on the diver underwater hydroacoustic communication station providing a voice communication sonar. In addition, as receivers of foreign satellite navigation system used by the GPS system. Furthermore, sonar priemoizluchatel made portable. Also this problem is solved by the creation of the underwater unit diver, comprising a display device, a computing unit, in which additionally introduced sounder, Doppler log, at least one biometric sensor, a heading sensor, heel, trim, the second receiver external navigation system, a second sonar transceiver -peredatchik, the depth determination device, a timer, wherein the computing unit computes the current position based on data received from the sonar, Doppler-lag rate sensor, heel, trim, FOSTER Cove external navigation system, a display device configured to display the current trajectory and predetermined path of movement, at least one diver between providing a ship by a diver and the object of the search, wherein the computing unit input coupled to the outputs of sonar, Doppler-lag, a biometric sensor, a heading sensor, heel, trim, the second receiver external navigation system apparatus determining the depth, the timer, one input of which is connected to the second straight hydroacoustic iemo transmitter, and a second output connected to a display device.
