Description

The utility model relates to wireless security systems and control of physical parameters, performance and safe operation of pressure vessels.

The system of remote control of physical parameters, including the pressure of process media, is widely used in petrochemical industries (Big Encyclopedia of Oil and Gas (BENG) ngpedia.ru).

The closest analogue (prototype) of the proposed Remote Wireless Monitoring System is "Device for remote pressure measurement" Pat. RU 2528555 C2 Russian Federation, IPC G01L 9/00 (2006.01), which contains a serially connected master oscillator, a power amplifier, a duplexer whose input-output is connected to a transceiver antenna, a phase detector, the second input of which is connected to the first output of the narrow-band filter, and a registration unit, the second input of which is connected through a phase meter to the outputs of the master oscillator and a narrow-band filter.

Known "Device for remote measurement of pressure" Pat. RU 2244908 C2 Russian Federation, IPC G01L 9/00), which contains a transceiver with a transceiver directional or omnidirectional antenna, serially connected master oscillator, power amplifier, duplexer, the input / output of which is connected to the transceiver antenna. In this case, the transponder is made in the form of a multi-tap delay line on surface acoustic waves, including an interdigital transducer, which is made in the form of two comb electrodes.

The well-known "Method and device for measuring pressure inside pipelines" Pat. RU 2470274 C1 Russian Federation, IPC G01L 11/00 (2006.01), in this method, the pressure of the product pumped through the pipeline is measured by the method of spectral analysis of technological pipe vibrations using an information-measuring system that includes vibration sensors connected by cable lines to the dispatch system computer item.

The above analogs can be used to control physical parameters in pressure vessels.

Known devices basically provide pressure measurement directly in the places of their installation and do not provide temperature and humidity control.

The disadvantages of these devices are cumbersome, the complexity of the design and installation, the resulting effect of "reverse operation" due to spasmodic transitions and the formation of interference, short termination of signal reception.

The utility model does not have these shortcomings and allows you to remotely (via radio channels) to control the physical parameters of vessels operating under pressure, of any size and any capacity in the oil, gas, chemical industry, gas supply to consumers, etc. When operating pressure vessels, much attention is paid to safety issues. The most important issue remains the issue of monitoring and ensuring the safe storage of large stocks of vessels operating under pressure in various technological processes.

The objective of the utility model is to increase the safety, reliability and efficiency of parameter control, increase the explosion and fire safety during work in various technological processes.

The tasks are successfully solved by the remote wireless monitoring system (SDBK), consisting of a module that includes a universal (protected) sensor for monitoring P - pressure, H - humidity, T-temperature, located inside the pressure vessel body, radio signal transmitter, element nutrition. The signal receiver can be implemented both on the basis of a personal computer, a mobile phone, and a separate information display unit with a graphical and text interface.

The device proposes to abandon a large number of interchangeable control sensors for parameters, replacing the universal control sensor P - pressure, H-humidity, T-temperature, placed in one housing with a signal transmitter and a battery. The device is supposed to be fixed on the inner surface of the vessel body, operating under pressure at the stage of vessel manufacture. This allows you to control without violating the integrity of the vessels, while the reliability of the structural elements of the SDBK is comparable with the life of the pressure vessel. For example: metal-composite vessels of the BMK-300 brand, in accordance with the technical conditions, have a life of 10 years, modern sensors used in the SDBK system without replacing the battery also provide long-term uninterrupted operation. Depending on the capacity of the battery from 10 to 15 years of operation.

The design of the vessel operating under pressure with SDBK is presented in figure -1, where 1 is SDBK, mounted inside the vessel body.

The SDBC device is shown in figure 2, where 1 is the device body, 2 is a sensitive element (sensor), 3 is an information transmitter, 4 is a power supply.

Using the proposed device provides the possibility of wireless remote and safe monitoring of the necessary parameters in warehouses, industrial premises, laboratories.
