Description

The invention relates to the field of digital communication systems and computing systems, namely to devices for collecting, processing and transmitting data and can be used both as an independent device and as part of automated information-measuring and control systems, including those implemented on SCADA and IIoT platforms , in various industries, mainly in the oil and gas industry.

From the existing prior art, a device for collecting, processing and transmitting telemetric information is known, containing a housing with the possibility of mounting on horizontal and vertical surfaces, a printed circuit board on which a power supply with a power supervisor is located, a microcontroller with large-size RAM and permanent memory, a real-time clock with built-in non-volatile memory and lithium backup battery, RS-232 interface converter, RS-485 interface signal converter with galvanic isolation unit (patent RU 2 449 346 C1, 04/01/2011, published 04/27/2012 Bull. No. 12).

The disadvantage of the known device is the absence of a mini computer, an uninterruptible power supply, an explosion-proof housing in its composition, which significantly limits its functionality and computing capabilities, excludes autonomy when the external power supply is turned off, limits its use at low temperatures and in explosive areas, there is no support known protocols and formats of transmitted data, and therefore it may be difficult to integrate with automated systems.

In the course of the search through the sources of scientific, technical and patent information, no device was found that has the same set of essential features and provides the claimed technical result. This circumstance allows us to conclude that the present invention is a technical solution to the problem, is new, has an inventive step and is industrially applicable.

The task to be solved by the claimed technical solution is the creation of a device that provides a high speed of collection, fault tolerance in the processing and transmission of data from digital or analog sensors, their primary processing using software and a high speed of data transmission over communication channels in information measuring and control systems implemented, including on SCADA and IIoT platforms, in conjunction with a video data stream during drilling, workover and operation of oil and gas wells, data transmission via various protocols and formats (HTTPS, MQTT, LAS, WITS, WITSML, JSON ), real-time data acquisition, operation of the device in hazardous areas and in a wide temperature range from -40 to +70°C.

The technical result is the reception of data from analog and digital sensors and devices, the binding of such data to video data, the output of data in graphical form on the screen of a computer or mobile device, the transmission of data to various automated systems implemented, including on SCADA and IIoT platforms, according to different protocols and formats (HTTPS, MQTT, LAS, WITS, WITSML, JSON), use in hazardous areas and in the temperature range from -40 to +70°С. The solution of this problem is achieved due to the fact that it contains a compact explosion-proof housing with the possibility of mounting on vertical and horizontal surfaces, connectors for connecting sensors and devices, input devices for receiving and processing data from sensors and devices, a data bus of the EIA / TIA-485 standard, mini computer for converting and transmitting received data, RJ interface for connecting to a local area network or communication equipment, power supplies, uninterruptible power supply, all components of the device with a wide operating temperature range.

The device for receiving, converting and transmitting data from sensors and devices consists of 12 and 24 V power supply units, a block of analog input modules, an explosion-proof device housing block, an uninterruptible power supply unit, a mini computer unit with specialized software installed on it, a data bus unit EIA/TIA-485 standard.

The proposed device for receiving, converting and transmitting data from sensors and devices is illustrated in the drawing. The device contains a 24 V power supply unit 1 for powering connected analog and digital sensors and devices, as well as analog modules with a constant voltage of 24 V, a block 2 of analog input modules for receiving and processing signals from analog sensors and devices, a block 3 of the explosion-proof device housing for the possibility of operation in hazardous areas, unit 4 of an uninterruptible power supply for autonomous power supply in the event of an external power failure, unit 5 12 V power supply for supplying power to connected analog and digital sensors and devices, as well as a mini computer with a constant voltage of 12 V, unit 6 mini computer with specialized software installed on it, which allows converting and transmitting data, block 7 of the EIA / TIA-485 standard data bus for data exchange between the mini computer and analog input modules, digital sensors and devices.

The device works as follows. The uninterruptible power supply (block 4) is powered by an external 220 V AC power supply and is the source of power for the power supplies (blocks 1 and 5), which in turn convert the input voltage to 24 and 12 V DC. Power supply 24 V (block 1) powers the sensors and devices connected to the device, as well as analog modules (block 2) that require a 24 V DC power supply. The 12 V power supply (block 1) powers the sensors and devices connected to the device, as well as a mini computer ( block 6), requiring a DC voltage of 12 V. Analog sensors and devices are connected via connectors on the device case to analog input modules (block 2), digital sensors and devices - to the data bus (block 7). Analog input modules (block 2) receive signals from sensors and devices and convert them into digital form. A mini computer with specialized software (block 6) interrogates analog input modules (block 2) and digital sensors and devices via a data bus (block 7), the mini computer saves the received data to a database located in its non-volatile memory, converts it into a graphical form and in various formats (LAS, WITS, WITSML, JSON). The mini computer transfers the converted data to the user, or to an automated system (information-measuring, control), including the cloud, via the HTTPS, MQTT protocols. The mini computer software allows you to record video data from IP-surveillance cameras, store them in non-volatile memory and link them to the data received from sensors and devices, which allows the user to quickly receive video data at a selected moment in time from sensor and device data. An application programming interface (API) is used to interact with external systems with the device. The mini computer is equipped with an RJ standard interface, which allows you to connect the device to a local area network or other communication equipment. The mini computer has a visual WEB-interface for user interaction with the device. Thanks to the WEB-interface using a WEB-browser, the user can configure the device, obtain real-time data from sensors, devices and video cameras in graphical form, generate and upload reports on the recorded data from devices and sensors.
