Description

The utility model relates to the field of fire alarm equipment, namely, to the control and regulation devices of fire alarm systems.

A well-known fire and explosion safety control system, including fire and gas sensors, a computing device, process parameters sensors connected to the corresponding inputs of the computing device, as well as controls electrically connected to the computing device, equipment emergency shutdown subsystems with the formation of a multi-level emergency shutdown system organized by functional and / or territorial-functional basis with the possibility of automatic and remote shutdown of equipment by government (patent RU 53467 the U, IPC G05B 15/00).

Also known is an automated gas pollution control system (according to methane) for air in working areas in hazardous areas (galleries and compartments of compressor compressor superchargers, reduction rooms, switching units and instrumentation and control equipment at gas distribution stations, fuel and starting gas treatment units), including gas detection sensors connected to a computing device, as well as to governing bodies of the emergency exhaust ventilation system (Gazprom standard 2-3.5-454-2010 "Rules for the operation of gas mains odes ").

These stationary automated systems provide:

- process control and emergency shutdown of equipment both automatic and remote;

- control of the main parameters in full only when conducting the technological process (including the control of gas contamination for a hazardous production facility for gas transport only in explosive rooms).

After stopping the process, completely shutting down and releasing equipment and communications from explosive atmospheres, disabling them for scheduled or emergency repair (fire) work, the known systems do not provide:

- gas contamination control in the pipe space of equipment and communications;

- monitoring the pressure in temporarily sealing devices installed according to the approved technology through technological holes into the in-pipe space of the repaired section of the pipeline disconnected by shutoff valves from the place of hot work on the linear part of the main gas pipelines.

There is a known regulation on the preparation and conduct of repair (fire) work at hazardous production facilities of the Unified Gas Transportation System of Russia, which establishes methods and methods for shutting off valves on equipment and pipelines, bleeding gas, installing and monitoring overpressure, cutting technological holes with an additional installation in the pipe end sealing devices, purging, welding and installation work, displacement of the gas-air mixture from the repaired About equipment or pipelines. At the same time, gas contamination in the hazardous area, overpressure in the pipeline, and pressures in temporarily sealing devices are controlled by separate measuring instruments — portable gas analyzers, manometers, drag gauges and direct pressure gauges (standard Gazprom RD - 2005 “Typical Instructions for the Safe Carrying Out of Fire Operations at Gas Objects” Gazprom OJSC, developed by the Scientific Research Institute of Natural Gases and Gas Technologies - VNIIGAZ in accordance with the “Standard Instruction for organizing the safe conduct of hot work at explosive and explosive and fire hazardous facilities ”, approved by the State Technical Supervision Service of Russia on June 23, 2000)

In accordance with the specified regulations:

- for the entire period of repair (fire) works, they monitor the state of the air environment, including the in-pipe space of the repair section in explosive and working areas with portable gas analyzers;

- designate duty observers for the state of the hazardous area in order to signal the immediate cessation of work in the event of a pre-emergency situation or additional danger;

- gas contamination is controlled by portable gas analyzers at least every 30 minutes;

- before cutting technological holes in the gas pipeline, pressure is measured by pressure gauges, which are installed on disconnecting devices (crane units) and at the place of repair (fire) work. Manometers are connected to the gas pipeline using a tube with a special conical nipple, pressed into a hole with a diameter of 6-8 mm, drilled in the upper part of the gas pipeline at the place of repair (fire) work;

- finishing cuts of the gas pipeline and welding and installation work on its restoration is performed after installing temporarily sealing devices with gas in the pipe and foundation pit not more than 20% of the lower ignition concentration limit;

- during repair (fire) work related to the separation of the gas pipeline, rough cuts are made after the localization of the place of work with temporarily sealing devices;

- temporarily sealing devices are installed in the gas pipeline at a distance of at least 8-10 m in both directions from the place of repair (fire) work between the technological holes and the place of work. A temporarily sealing device placed in a gas pipeline is pumped with air or inert gas to the required pressure;

- pressure control inside the temporarily sealing device is carried out by pressure gauges.

However, these parameters, the monitoring of which must be ensured when performing work of increased danger on gas equipment and gas pipelines that were taken out for repair, are not automatically controlled and cannot be controlled by well-known automated fire and explosion safety control systems or automated process control systems.

The process of an emergency in the working area, including due to changes in the in-pipe space, is often instantaneous and the slightest delay in making a decision can lead to an air-gas mixture explosion, an accident and industrial accidents. An important role is played by the method of alerting workers involved in the corresponding stages and carrying out hot work, including workers in the foundation pit or trench, at the repair section of the gas pipeline or other equipment of the main gas pipeline facility.

The warning process is complicated by the fact that during the repair (fire) work, increased noise is characteristic due to the working internal combustion engines of power plants, mechanisms, grinders, etc., which makes it difficult to immediately alert and, therefore, immediately evacuate workers from the danger zone.

These problems are eliminated in the technical solution according to patent RU 108656 U, publ.: September 20, 2011., Which declared a safety control stand during repair work on gas main facilities, consisting of a gas analyzer and manometers, characterized in that it is additionally equipped with a fire alarm with light and sound alarms, gas detectors and two pressure monitoring units, each of which consists of two pressure control manometers, an overpressure control manometer and an electronic pressure sensor a digital display, which is connected with both temporary-sealing devices, and with a fire alarm with light and sound alarms, which, in turn, is connected to a gas analyzer connected to gas sensors located in technological openings for measuring gas contamination in the pipe .

In addition, the booth does not provide control algorithms for the possibility of connecting dispatch systems and access control systems of third-party manufacturers.

The objective of the utility model is to eliminate these technical problems of the prototype.

The technical result consists in the possibility of connecting dispatch systems and access control systems of third-party manufacturers to the stand, and when using the stand for staff training, it is possible to simulate various equipment malfunctions.
