Description

The invention relates to environmental information stations, namely, stations for automatic control of the physicochemical, radiation state of atmospheric air.

The use of such stations in areas of oil and gas fields, metallurgical, chemical, nuclear industries, etc., is especially relevant. The creation of effective automatic control tools operating in difficult climatic conditions without human intervention with a sharp difference in temperature, humidity, and pressure is a complex problem, the solution of which is a matter of interest all over the world. Such stations, created with varying degrees of automation, are used, for example, in the USA (Chicago, Los Angeles, New York), Japan (Guma Prefecture, Nagoya), Great Britain (Telstor stations), Poland ( Gornosiles Industrial District), etc.

Known, for example, the station described in patent RU No. 2078357, IPC: G 01 W 1/02 with priority from 04/27/97), containing a housing, a support frame, a meteorological complex, measuring equipment for air pollution, air intakes, diagnostic, control and information transmission, air conditioning and heater, temperature sensors for heated and cold air. The meteorological complex at such stations contains meteorological equipment for measuring temperature, humidity, and the direction, strength and speed of the wind. Weather sensors are located on a remote rod mounted on the station body. Such stations belong to the stationary type of automatic stations for environmental environmental monitoring and do not have the ability to expand the controlled area and provide operational control of environmental parameters in certain areas of the surveyed area.

The disadvantages of the known station, which includes meteorological equipment, are the limited controlled area and the inability to provide operational control of meteorological parameters of the environment (air).

A portable complex weather station is also known (see, for example, patent RU No. 2199139, IPC G 01 W 1/02 with priority dated 08/28/2001), selected as a prototype and containing a thermostatic housing with measuring, microprocessor and information transmitting equipment located inside it and weather sensors.

It is designed to control air pollution and measure the meteorological parameters of the environment (air). The station is located in a container made of insulating material. Weather sensors monitor temperature, relative humidity, wind direction and strength, solar radiation, pressure, precipitation and vertical wind speed.

However, the known station does not have the ability to make autonomous continuous monitoring of the amount and intensity of precipitation, because it is not equipped with appropriate instruments and equipment.

The disadvantages of the known weather station are the inability to measure the amount of precipitation due to the lack of instruments for measuring and providing information on the amount and intensity of precipitation.

The present invention is the creation of such a portable integrated weather station, which would have the ability to measure the amount of precipitation and transmit information.

The problem is solved in that a portable weather station containing a thermostated housing with measuring, microprocessor and information transmitting equipment located inside it, and weather sensors, is equipped with a rain gauge made in the form of a welded conical neck and drain plug mounted vertically in a thermostated housing moreover, the neck is directly connected with the atmosphere and is equipped with an electric heater with a temperature sensor, mounted on an external turn NOSTA neck, wherein a bottom area of the internal volume of the vessel is brought drain conduit with an electromagnetic valve, and below the level of the inlet opening of the drain conduit to the vessel integrated differential pressure sensor with temperature compensation, is electrically connected to the solenoid valve control unit and an electric heater with a temperature sensor.

The technical result is achieved by the fact that a newly created instrument for measuring the amount of precipitation is introduced into the portable integrated weather station - a precipitation meter and designed for automatic and round-the-clock measurement of the amount of precipitation in the form of rain, and also suitable for measuring solid precipitation in the form of snow, hail, etc. .p., with subsequent transfer of information to the data center. The sediment meter works on the principle of the difference in pressure of a liquid column in a calibrated vessel relative to atmospheric pressure.

The use of the proposed portable integrated weather station, for example, at aerodromes, spaceports, in agro-hydrogeology, etc. allows you to give a significant economic effect due to the provision (along with control of temperature, relative humidity, direction and strength of the wind, solar radiation, pressure, vertical wind speed) measure the amount of precipitation by introducing a precipitation gauge into the meteorological station, working on the principle of changing the difference in pressure of the liquid column (column of collected precipitation) in a calibrated vessel relative to atmospheric pressure; however, the precipitation meter provides continuous monitoring of the amount and intensity of precipitation, which is confirmed by tests of prototypes made using the proposed technical solution.

The invention is illustrated by the drawing, which shows a General view of a portable integrated weather station and given the device of the precipitation meter.

A portable complex weather station consists of the following main units and parts: a thermostated housing 1 with measuring equipment 2 located inside it, microprocessor equipment 3, transmitting equipment 4 and weather sensors 5. A weather gauge 6 is introduced into the composition of the weather station, made in the form of an etched vessel 7 with a conical neck 8 and a drain plug 9 mounted vertically in a thermostatic housing 1. The conical neck 8 is directly connected to the atmosphere and is equipped with an electric heater 10 with a sensor temperature 11, fixed on the outer surface of the neck 8. A drain pipe 13 with an electromagnetic valve 14 is connected to the lower part 12 (into the inner volume of the vessel 7 into its bottom zone). A differential pressure sensor 15 s is built into the vessel 7 below the level of the inlet of the drain pipe 13 temperature compensation, electrically connected to the control unit 16, which controls the electromagnetic valve 14 and the electric heater 10 with a temperature sensor 11. The control unit 16 is part of the microprocessor 3.

Weather sensors 5 are located outside the housing 1 and provide control and measurement of temperature, relative humidity, wind direction and strength, solar radiation, pressure and vertical wind speed. The precipitation meter 6 introduced from the meteorological station is intended for automatic and round-the-clock measurement of the amount of precipitation in the form of rain, snow, hail. The precipitation gauge 6 operates on the principle of a change detected by the differential pressure sensor 15 of the pressure difference of the liquid column (column of collected precipitation) in the calibrated vessel 7 relative to atmospheric pressure.

The weather station has a circular handle 17 for carrying, a supporting skirt 18 and a removable protective cap 19.

The conical neck 8 has a predetermined inlet (upper) cross-sectional area (precipitation collection area) and is intended to collect precipitated atmospheric precipitation in a scoured vessel 7. A control temperature sensor 20 is installed on the lower part of the vessel 7.

A portable integrated weather station is operating in the mode of measuring the amount of precipitation by precipitation gauge 6 as follows.

The weather station is installed outdoors with the protective cap 19 removed.

For power supply weather station mainly use batteries introduced into the weather station, in addition, it has a connection to external power sources. The portable integrated weather station operates in an automatic mode for collecting, processing and transmitting information to a data center.

Atmospheric precipitation in the form of rain, snow, hail, falling into the conical neck 8, flows into the scoured vessel 7, where it accumulates to a predetermined level, while the signal from the differential pressure sensor 15 with temperature compensation (temperature correction) microprocessor 3 reads the sensor 15, generates and transmits information via communication channels to the consumer (to the data processing center), at the same time, the control unit 16 of the microprocessor 3 affects the opening, closing of the electromagnetic valve 14 and constantly draining through t uboprovod excess liquid 13 maintains a predetermined liquid level in the vessel 7, is necessary for accurate determination of precipitation (liquid). In case of precipitation in the form of snow or hail (solid precipitation) when it enters the neck 8, solid precipitation is liquefied (melted) by heating from an electric heater 10, which is turned on (off) by a command (signal) from the control unit 16 depending on the readings ( by the signal) from the temperature sensor 11, which clearly monitors and controls the set temperature on the neck wall 8. The temperature compensation (temperature correction) of the differential pressure sensor 15 is taken into account by the microprocessor 3 according to the indications (by the signal) from yes snip temperature 20 constantly monitors the temperature at the vessel wall 7, which is integrated and communicates with the vessel 7, the sensor 15.

Drain plug 9 is designed to completely drain the liquid (precipitation) from the vessel 7 and flush it from possible solid precipitation (pollution in the form of dust, etc.) during routine maintenance.

The introduction of the portable integrated weather station precipitation gauge 6, operating on the principle of changing the difference in pressure of the liquid column in the calibrated vessel 7 relative to atmospheric pressure, provides a measure of the amount of precipitation, which performs the task.
