HYDROCHEMICAL BOTTOM STATION FOR GEOLOGIC MONITORING OF WATER AREAS Russian patent published in 2015 - IPC G01V11/00 

FIELD: radio engineering, communication.

SUBSTANCE: bottom station includes a device housing (1) with an ellipsoidal shape placed at the bottom (2) of a water area and a repeater buoy (3) connected to said housing. The device housing (1) holds a microcomputer (9), modems (10, 11) for receiving and transmitting information via cable links (4) or a radio link, a power unit (12), a channel switch (13), an accumulator unit (14), a spectrophotometer (17), an electronics unit (24), a hydroacoustic module (28) for communication with a support ship and positioning at the bottom, as well as sensors for measuring conductivity (18), temperature (19), pressure (20), flow rate (21), pH (22), sound speed (23), a constant magnetic field magnetometer (26), a gamma-ray spectrometer (27), sensors for detecting carbon dioxide gas (29), oxygen (30), nitrogen (31), methane (32), a turbidity meter (33) and a microbe sensor (34). The electronics unit (24) includes broadband seismic signal detectors and a three-component digital seismograph (25). The device housing (1) is fitted in the lower part with a rubber boot (5) and is placed in a reinforced-concrete ballast (6). The reinforced-concrete ballast (6) is linked to the device housing (1) by a strap (7) and an electrochemical circuit breaker (8).

EFFECT: broader functional capabilities and high reliability of obtained data.
