FIELD: instrument making.SUBSTANCE: network to monitor area of water is made as capable of information exchange with its external receiver, is formed by anchored metering buoys, having positive buyoancy, equipped with garlands of metering sensors distributed along a rope cable that connects a buoy with an anchor, a monitoring and control system, facilities to record controlled parameters of the water medium, made as capable of data transfer along a hydroacoustic channel. Metering buoys are distanced from each other at the distances that correspond to the distance of transceiving along the hydroacoustic channel, which is maximum permissible for this area. The monitoring and control system of each buoy is equipped with facilities to measure sound speed, distributed along the length of the cable rope and at least three hydroacoustic modems, the lower of which is installed on the rope cable with the possibility to be positioned in the bottom layer, the second one - on the metering buoy or near on the rope cable, and the third one is equidistant from the first and the second hydroacoustic modems. At the same time each metering buoy is installed as capable of information exchange along the hydroacoustic channel with at least one buoy of the network. Besides, at least one of the network buoys is made as capable of exchange along a radio channel with the external information receiver.EFFECT: increased actual distance of data transfer along a hydroacoustic communication channel.2 dwg |
