The utility model relates to instrumentation, in particular, to systems for monitoring the position of moving objects, and can be used to control the position of moving objects of marine equipment - inhabited and uninhabited underwater vehicles, hydrographic buoys, flexible long towed antennas.

Known gyroscopic instruments for monitoring the angular position of a moving object, for example, an inclinometer [1].

A known system for controlling the position of an object, providing real-time measurement of data and transferring them to a top-level controller, contains a block of primary sensors, which includes accelerometers and magnetometers, a signal pickup unit, an analog-to-digital conversion (ADC) unit, and a calculator unit [2 ].

The known system provides the measurement of heading angles, roll, trim of the object and data transmission to the upper level controller via the standard RS-232 interface.

The known system can be used to control the position of the immersed object of marine technology, is closest to the expected technical essence and, therefore, is taken as a prototype.

A disadvantage of the known prototype system is the lack of information when monitoring the position of the immersed object of marine equipment, in particular, flexible long towed antennas (GPBA).

The disadvantage of the known prototype system is due to the fact that the known system does not provide information about the depth of the object.

The technical result of the utility model is to increase the information content when monitoring the position of the immersed object of marine equipment by

determining its immersion depth and the ambient temperature at that depth.

To ensure the specified technical result in the position monitoring system of the immersed object of marine equipment for real-time transmission of data to the upper level controller, which contains in series a block of primary sensors, which includes accelerometers and magnetometers, a signal pickup unit, including an analog signal generation circuit and a circuit power supply, analog-to-digital conversion (ADC) unit and calculator unit, new features have been introduced, namely: a pressure sensor unit has been introduced into its composition I, consisting of a series-connected pressure sensor and a buffer amplifier, the power input of which is connected to the power circuit, and the output to the ADC unit, while a temperature sensor is introduced into the primary sensor unit.

The achievement of the technical result is explained by the fact that the introduction of pressure and temperature sensors into the monitoring system for the position of the immersed object of the marine equipment allows obtaining information about the depth of the object and the water temperature at the measurement horizon.

The essence of the utility model is illustrated in FIG. 1, which shows a block diagram of the proposed device.

The control system for the position of the immersed object of marine equipment consists of block 1 of a pressure sensor, block 2 of primary sensors, block 3 of signal pickup, block 4 of the ADC, block 5 of the calculator.

Block 1 of the pressure sensor includes the actual pressure sensor type MD 10-6-V TU 4212-163-00227459-98, the sensitive membrane of which directly contacts the working medium, and a buffer amplifier, from the output of which an analog signal is proportional to the external pressure.

Block 2 of the primary sensors contains a triad of 6 Silicon Designs1210L-005 accelerometers, providing roll and trim angles measurement, a triad of 7 magnetometers on PNBI. resistance PNBI. 405226.001.

The signal pickup unit 3 comprises sensor power circuits and a circuit for generating analog sensor signals.

Block 4 of the ADC contains a 14-bit ADC MAX194AERE.

The proposed device works as follows: the input of an 8-channel switch unit 4 of the ADC receives analog signals from all sensors. Block 4 provides the conversion of the received analog signals into digital form.

Block 5 of the calculator provides the calculation of the course, roll angles, trim, the transfer of these results and data on measuring temperature and pressure to the communication line via the RS-485 interface.

The application of the proposed device made it possible to provide measurement and transmission to the upper level controller via the RS-485 interface of the following parameters characterizing the position of the submerged object of marine equipment:

Parameter Name unit of measurement measurement range RMS error 1. The course relative to the magnetic meridian angle hail. 0 ... 360 0.5 secφ (φ - geographical latitude of the measurement site) 2.
