Description

The utility model relates to oceanology, namely to information and measurement technology, and can be used for hydrophysical research in the seas and oceans.

One of the methods for monitoring wave processes in coastal areas is the use of recorders with built-in or remote hydrostatic pressure sensors. This approach makes it possible to synchronously record sea level fluctuations at several points in the coastal zone. At the same time, it is required to simultaneously record temperature and pressure readings of the atmosphere, to be able to remotely control and transmit data. This problem is especially relevant when using remote cable hydrostatic pressure sensors.

An autonomous hydroacoustic observation station is known, the hydroacoustic antenna module of which contains several structurally integrated hydroacoustic recorders with preamplifiers built into them, a single time system common to all hydroacoustic recorders and an attitude determination system, the outputs of which are connected to the inputs of the hydroacoustic recorder processors. Each hydroacoustic recorder is made in the form of a series-connected hydroacoustic pressure receiver, an amplifier with a filter, an analog-to-digital converter, a digital information processor and storage device, and a power source (RF patent No. 24890 U1, publ. 27.08.2002).

The disadvantage of the known analogue is the limited scope of its application, namely the absence of additional sensors for the parameters of the measured medium, which does not allow for the entire range of ongoing research.

A marine autonomous bottom station is known that solves the technical problems of the registrar, made in the form of a deep-sea self-floating carrier of geophysical equipment installed at the bottom of the water area (RF patent No. 2572046 C1, publ. 27.12.2015). The station includes a registration unit, a synchronization unit, a hydroacoustic channel unit, a power supply unit, an orientation determination unit made in the form of tilt and azimuth sensors, and an information storage device placed in a sealed container.

The disadvantage of the known analogue is the limited scope of its application, namely, the use of the station only in the option of setting on the bottom and the inability to measure atmospheric temperature, atmospheric pressure, and the hydrostatic pressure field, which narrows the range of tasks it can solve.

Closest to the claimed is the Autonomous recorder of hydrophysical fields (useful model RU No. 171967 U1, according to application 2017109315, published: 06/22/2017 Bull. No. 18).

The disadvantage of the closest analogue is the limited scope of its application. Since it does not take into account atmospheric temperature and atmospheric pressure, as it is completely immersed in water. In addition, the immersion of the measuring unit in water does not allow remote control of its operation, as well as the use of measurement results before raising it to the surface.

The objective of the utility model is to expand the scope of its use, allowing to take into account atmospheric temperature and atmospheric pressure, as well as to remotely control its operation, and use the measurement results before lifting it to the surface.

Thanks to a new set of essential features in the claimed device, the scope of its application is expanded through the additional use of a real-time clock module, a digital sensor of atmospheric temperature and atmospheric pressure, a GSM / GPRS remote control and data transmission module, a Schmidt trigger, and a hydrostatic pressure sensor, connected to the Schmidt trigger via a coaxial load-carrying cable to ensure its autonomous use, the claimed technical result is achieved.

The claimed device works as follows.

The waterproof housing of the autonomous hydrostatic pressure recorder is installed in the coastal zone of the reservoir under study, and the hydrostatic pressure sensor (see block 5 in Fig. 1) is immersed in water to the required depth. In this case, electrical contact with the sensor is provided by means of a coaxial load-carrying cable.

Turning on the power in the microcontroller control unit (see block 1 in Fig. 1) ensures the operation of the device. A thermostatted crystal oscillator (see block 3 in Fig. 1) clocks the microcontroller control unit.

Further, the hydrostatic pressure sensor, through a coaxial load-carrying cable, generates a signal with data on the measured pressure, which is fed to the input of the Schmidt trigger (see block 4 in Fig. 1). The received signal is a smoothed sequence of pulses, the repetition rate of which corresponds to the nominal value of the measured pressure.

In the Schmidt trigger, the received signal is converted to the form necessary for the operation of the microcontroller control unit.

Then, the signal from the output of the Schmidt trigger goes to the microcontroller control unit, where the pulse repetition rate is converted into the nominal value of the measured hydrostatic pressure.

In parallel with this, the microcontroller control unit reads data from the atmospheric pressure and atmospheric temperature sensor (see block 6 in Fig. 1) via a serial communication bus. In addition, the microcontroller control unit reads the time from the real-time clock module (see block 2 in Fig. 1) via the serial communication bus.

The generated data packet containing the readings of the hydrostatic pressure sensor and the atmospheric temperature and atmospheric pressure sensor, synchronized in time from the real-time clock module, is written to the non-volatile solid-state memory SD (see block 8 in Fig. 1) via the serial communication bus.

In addition, via the serial communication bus, using the functionality of the GSM/GPRS module, the generated data packets are sent to a remote server via the GSM radio channel.

By using the functionality of the GSM/GPRS module during operation, remote operations are performed to configure or stop the device, in accordance with the operation algorithm.

The formula components of the presented utility model are interconnected by assembly operations and are in functional and constructive unity.
