SYSTEM FOR REMOTE DETERMINATION OF CHEMICAL AND PHYSICAL PARAMETERS OF AQUATIC MEDIUM AND CONTROLLING DEVICES FOR PREVENTING SUFFOCATION Russian patent published in 2011 - IPC G01N27/06 

FIELD: physics.

SUBSTANCE: system for remote determination of chemical and physical parameters of an aquatic medium and controlling devices for preventing suffocation is in form of a transmitting station mounted on a buoy and a receiving station mounted on the shore. The transmitting station has a power supply which is connected through a timer to components of the transmitting station, a temperature sensor, a temperature converter, a pH sensor for the top water layer, a pH converter, a pH sensor for the bottom water layer with conversion of pH. The pH sensor converters are connected to three inputs of a three-input switch which is connected by the output to an analogue-to-digital converter, which is connected through a signal transmitter to a transmitting antenna. The receiving station has a power supply, a receiving antenna, a signal receiver, a signal determination unit which is connected by the output to a switch, whose three outputs are connected to devices for processing data and displaying temperature and pH measurement results. The devices for processing data and displaying temperature and pH measurement results are in form of series-connected demodulator, decoder, memory register and digital display. Outputs of memory registers of the devices for processing and displaying pH are additionally connected to inputs of a computing unit. The output of the unit is connected to an actuating unit which passes commands to the power equipment to switch on the aeration device to prevent suffocation.

EFFECT: possibility of remote monitoring of the state of a water body and automatically switching on equipment for preventing suffocation.
