Description

The invention can be used on large highways. The essence of the proposed technical solutions is to collect information about the state of the environment in controlled areas and transmit this information to the control terminal. Based on the analysis of the data obtained, the terminal determines the likelihood of ice formation in the controlled area and issues a command to stationary processing facilities for the proactive application of anti-icing reagents. Stationary means are made with the possibility of inclusion in any sequence and are made in the form of a mobile candy bar. The technical result is a reduction in the complexity of processing the roadway and the accuracy of the executive function of the system.

The invention relates to automated technical means for counteracting icing phenomena and can be used to combat icing on major highways, ring roads, as well as to counteract ice formations in the waters of offshore economic facilities.

The prior art methods and devices for deicing processing according to US patents No. 4557420 dated 12/10/1985 [1], NL No. 8900249 dated 03.09.1990 [2], JP No. 1129311 A dated 08.24.1999 [3], JP No. 10280252 dated 20.10 .1999 [4], application US No. 20031 78501 from 09/25/2003 [5], proposed as the closest analogues. The specified device consists of a pumping station, the hydraulic system of the road section and an automatic weather station. The pumping station is a container installed in the immediate vicinity of the road section being processed, inside which there are tanks for storing reagent, a pumping hydraulic system and control equipment. The equipment of the road section consists of spray heads located along the road section and connected by a hydraulic system. The automatic weather station is equipped with sensors for measuring air temperature, atmospheric pressure, relative humidity, rainfall (such as a "bucket"), wind speed and direction. A method for performing anti-icing treatment includes the normalized distribution of the liquid reagent on the surface of the road section by automatically or remotely activating the spraying operation, due to which the reagent is uniformly applied over the entire length of the road section.

The disadvantages of the known method and device include the lack of a pressure stabilization system in the hydraulic system and the ability to addressly control the head spray intervals, which in turn does not allow applying the reagent with a given accuracy to the road surface - spray control is performed by the only command “start spray”, after which sequential automatic switching on of spray heads for a single time interval set for all heads is performed. In addition, the composition of the known device includes such an expensive and requiring constant monitoring and maintenance element as accumulators, which reduce the overall reliability of the system, and to fill the entire hydraulic system with a reagent, including accumulators, it takes a long pump operation, which increases the cost of operating the device. A group of inventions is also known (patent RU No. 2287635 [6]), the essence of which is the calculated and strictly standardized deposition of the reagent, taking into account the meteorological situation and the relief of a particular road section. The technical result that can be obtained by implementing the well-known group of inventions [6] is to improve the quality of processing of the roadway and the accuracy of the executive function of the system by means of the possibility of spotting the reagent on a specific section of the road surface (up to several square meters) in real time .

To achieve the result, a method for automatically treating pavement with an anti-icing reagent involves measuring environmental parameters and / or the condition of the pavement on a controlled section of the road using meteorological sensors and / or pavement condition sensors installed along the road, sending the data to the control terminal, processing analysis of the obtained parameters with subsequent determination of the increase in the probability of ice on the control emom portion in the case of increase of probability of such calculation are given reactant distribution density steered by the control terminal address signal to actuators spray heads to ensure their incorporation into any sequence for applying the deicing agent with a given density. To achieve the result, the system of automatic processing of pavement with anti-icing reagent includes interconnected control terminal located along certain sections of roads of meteorological sensors and / or sensors of the state of the pavement, spray heads, while the spreading heads are installed on hydraulic lines laid along the road, the said sensors are made with the ability to measure environmental parameters in the controlled section of the road and / or with the state of the road surface and the transmission of the obtained data to the control terminal, made with the possibility of determining, based on the processing and analysis of the data, the increase in the probability of icing on the controlled area and in the case of determining the increase in such a probability of calculating the given distribution density of the reagent and the direction of the address signal to the spray actuators heads for applying a reagent with a given density, and said heads are configured to inclusion in any sequence.

The known system for providing anti-icing conditions (FOSS) according to the group of inventions [6] is a stationary system installed in close proximity to a controlled road section. One FOSS can control a section of the road with a length of up to 1.5 km or, if necessary, more. FOSS includes automatic meteorological station (AMS), central pumping station (CNS) and road section equipment.

The main components of the central nervous system are the cabinet with control equipment SOPO, hydraulic equipment and a high pressure pump.

The control equipment provides a convenient interface that allows you to manage FOSS and provide all the necessary data to the user in a visual form, control hydraulic equipment, stabilize the working pressure in the hydraulic system during processing of the road section with reagent, control the equipment of the controlled road section, receive and process data from the AMS, calculate the meteorological forecasting ice formation, calculation of the necessary distribution density of the reagent, automatic processing cycle reagent road section (including preparatory and final operations), monitoring the functioning of the electronic part of the control system, hydraulic equipment of the central nervous system and valve control modules of road sections, graphical display of the current state of hydraulic equipment of the central nervous system, data exchange with the central terminal, receiving and executing control commands from the central terminal and data storage for a given period of time.

The equipment of the road section includes blocks of road heads installed on hydraulic lines laid along the road sections, as well as control and power cables.

Automatic meteorological stations through the use of meteorological sensors provide highly accurate measurement of atmospheric parameters, such as air temperature, atmospheric pressure, wind speed and direction, humidity, amount and type of precipitation (with the possibility of determining "rain" or "snow"), the incoming energy of solar radiation . Monitoring the state of the pavement is provided by road sensors that measure the temperature of the pavement at various depths, as well as on the surface of the road, the concentration of the reagent on the road and its condition - “water” or “ice”. Road sensors can be connected both to the AMS and directly to the FOSS through the interface of the equipment of the road section. Road treatment with a reagent is carried out with increasing probability of occurrence of ice phenomena. This probability is determined on the basis of meteorological data issued by the AMS. Data is fed into the control equipment of the FOSS and the central terminal. Either the FOSS control system or the central terminal generates a processing command.

To optimally solve the problem, processing is carried out by applying a reagent before the occurrence of icy conditions or before precipitation, leading to icing.

The reagent is applied by spraying it with nozzles of a block of road heads located along the edge of the roadway. Each block serves a section of the road 10-12 m long and 2-3 lanes wide. The reagent is applied evenly with a given distribution density over the entire serviced area of the roadway.

The stability of the heads is ensured by increasing the performance of the pump and the inclusion of a pressure regulator in the hydraulic circuit, which eliminates pressure fluctuations during successive spraying of the reagent and allows you to maintain the specified flow characteristics of the spray heads.

In addition, the central nervous system control equipment used allows the generation of a sequential packet of signals including the head address, on-off commands, service bits and, as a result, control spray heads in any sequence, in particular, control arbitrary groups of heads, up to one specific head , setting the spray interval for them and the amount of applied reagent, which in turn allows you to control and process a specific road section in this place in real belt.

Significant disadvantages of the known group of inventions [6] are:

- the need to equip road sections with nozzles of a block of road heads installed on hydraulic lines laid along road sections, as well as control and power cables, hydraulic pumps;

- the need to equip AMC road sections;

- seasonality of intended use.

In addition, it is necessary to ensure the transportation of the reagent to the spray.

The noted shortcomings significantly increase the material costs of performing work related to the processing of highways with an anti-icing reagent. And taking into account the relatively low productivity when applying the known group of inventions [6], labor costs increase significantly, especially if the sections of the highway that are significant in length are simultaneously subjected to processing.

The objective of the proposed technical solution is to reduce the labor costs of automatic processing of the road surface with an anti-icing reagent.

The problem is solved due to the fact that the environmental parameters and / or the condition of the road surface are measured by meteorological sensors and / or road surface condition sensors on a controlled section of the road with an anti-icing reagent, and the received data is sent to the control terminal , they process and analyze the obtained parameters with the subsequent determination of the increase in the probability of ice formation in the controlled area and, in In the case of increasing this probability, they calculate the given reagent distribution density by sending an address signal to the actuators of the spray heads through the control terminal, enabling them to be turned on in any order for applying an anti-icing reagent with a given density, in which, unlike the prototype, the control terminal has meteorological sensors and / or pavement condition sensors, spray head actuators and spray heads and reservoir arches with anti-icing reagent are placed on an aircraft made in the form of a helicopter and / or airship located at the starting points of each distance of the highway, while the reagent contains additives in the form of granite chips.

The system of automatic processing of the pavement with an anti-icing reagent, including interconnected control terminal, meteorological sensors and / or pavement state sensors and spray heads, the aforementioned sensors are capable of measuring environmental parameters and / or the state of the pavement on a controlled section of the road and transmitting the received data to the control terminal, configured to determine based on the processing and analysis of the above data the probability of the occurrence of icy conditions in the controlled area and, in the case of determining the increase in such probability, calculating the specified distribution density of the reagent and directing the address signal to the actuators of the spray heads for applying the reagent with a given density, and the said heads are made with inclusion in any sequence in which , unlike the prototype, the system of automatic processing of the road surface with anti-icing reagent is made in the form of a mobile monoblo a.

New distinctive features are that the control terminal, meteorological sensors and / or sensors of the road surface, actuators of spray heads and spray heads and anti-icing reagent tanks are placed on an aircraft made in the form of a helicopter and / or airship, placed in the starting points of each distance of the motorway, while the reagent contains additives in the form of granite chips, a system for the automatic processing of road surfaces ice reagent made in the form of a mobile candy bar, eliminates the disadvantages of the known prototype [6], due to the need to equip the road sections with nozzles of the block of road heads installed on the hydraulic lines laid along the road sections, as well as control and power cables, hydraulic pumps, the need and equipment of the road sections of the AMS, and also to exclude downtime mechanisms in the offseason, which can significantly reduce the labor costs for carrying out these works.

In addition, the addition of granite chips to the reagent will increase the adhesion of tires to the road surface.

The essence of the proposed technical solution is as follows.

Equip the aircraft, made in the form of a helicopter or airship, meteorological sensors and / or sensors of the state of the road surface, control terminal, reagent tank, reagent spreading mechanisms.

As meteorological sensors, standard AMS of aircraft can be used, as well as regular means, for example, an airship of the Au 30 type, including a laser locator and aerial and thermal imaging tools (A. Frolov Airships in the Gazprom system. JSC Corporate Journal Gazprom ”(www.GAZPROM.RU), 2009, No. 6, pp. 40-41), which can be used to determine the characteristics of the road surface of the highway. The choice of an aircraft, which is an airship, as the carrier of the automatic road surface treatment system with an anti-icing reagent is due to the fact that the airship can land in almost any area, for example, to replenish the supply of reagent. The smoothness and speed of movement, as well as the reliability of flight, allow the reagent to be placed along a given path with a given density. The presence on the airship of a satellite navigation system allows for high-precision movement along the highway and timely make the necessary corrective actions in the work plan.

The proposed method and device for its implementation can also be used to localize ice fields in the waters of the northern seas, with marine economic objects located on them, for example, hydrocarbon production terminals.
