This application claims the priority of Korean Patent Application No. 10-2023-0001656 filed on Jan. 5, 2023, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The present disclosure relates to an apparatus for observing precipitation and a method for controlling the same.
Precipitation is an important element used for various fields, such as meteorological phenomenon monitoring, model analysis, and prediction in fields of meteorology, hydrology, and environment. Further, when heavy snowfall occurs in winter, disaster phenomena, such as traffic delays, suspension of aircraft operations, or destruction of facilities frequently occur due to icy roads so that it is important to quantitatively observe snowfall phenomena. However, it is not simple to accurately observe the precipitation and furthermore, when the form of precipitation is solid, such as snow, the observation error may be as large as 20 to 50%. Specifically, the snowfall phenomena are greatly affected by wind and an amount of snowfall is observed differently depending on a temperature, a humidity, particle shapes according to time and space, sizes, and density change so that it is difficult to accurately observe the snowfall phenomena.
Further, accurate measurement of precipitation is necessary to prepare disasters and calamities and obtain economic effects in the event of flood damage. However, measurement devices such as automatic drain type weighting precipitation gauges which are currently regularly operated in meteorological stations may not respond quickly to the situation problem of sudden snowfall occurring when a pure rainfall amount is measured. Accordingly, a quality of precipitation observation data is degraded due to a problem in that errors are included in precipitation observation data, or an observation error problem caused by fallen leaves or pine needles accumulated in the drain.
A related art of the present disclosure is disclosed in Korean Registered Patent Publication No. 10-1230558.
In order to solve the problems of the related art, an object of the present disclosure is to provide an apparatus for observing precipitation which solves a problem in that it is difficult to accurately observe snowfall, which is observed differently depending on wind, temperature, humidity, particle shapes according to time and space, sizes, and density change and a method for controlling the same.

For example, when the precipitation is sensed based on at least one of image information, sensing information, and information received from the external server 300, the determining unit 150 may determine the state of the precipitation based on at least one of the image information, the sensing information, and the information received from the external server 300.
According to the exemplary embodiment of the present disclosure, the control unit 140 may control at least one of the precipitation gauge 111 and the snowfall observation apparatus to measure precipitation based on the state information of the precipitation.
For example, when the state of the precipitation is determined as rain, the control unit 140 may control the precipitation gauge 111 to measure the precipitation. In contrast, when the state of the precipitation is determined as snow, the control unit 140 may control the snowfall observation apparatus to measure the precipitation (snowfall). The snowfall observation apparatus may include a camera sensor 113 for observing snowfall, a ruler 114 for observing-> measuring the snowfall, and a snowfall removal member 115.

As another example, when this apparatus 100 senses the rainfall during the snowfall observation, the control unit 140 stops measuring the precipitation using the snowfall observation apparatus and may start measuring the precipitation using the precipitation gauge 111. Further, when this apparatus 100 senses the snowfall during the rainfall observation, the control unit 140 stops measuring the precipitation using the precipitation gauge 111 and may start measuring the precipitation using the snowfall observing apparatus.
According to the exemplary embodiment of the present disclosure, the calculating unit 160 may calculate at least one of a rainfall amount, a snowfall amount, and a precipitation amount based on the measurement information of the precipitation.
For example, the calculating unit 160 calculates a state of the precipitation and at least one of a rainfall amount, a snowfall amount, and a precipitation amount in a predetermined time zone based on the measurement information of the precipitation, provides at least one of the rainfall amount, the snowfall amount, and the precipitation amount to an interface provided in the user terminal 200, and may provide a timing of occurrence of precipitation, a duration of the precipitation, and an interval for every type of precipitation.
According to the exemplary embodiment of the present disclosure, the determining unit 150 may determine whether the state of the precipitation is snow or rain.
For example, the determining unit 150 may determine whether the state of the precipitation is snow (snowfall) or rain (rainfall) based on at least one of the image information, the sensing information, and the information received from the external server 300.
As another example, when the precipitation is sensed, the determining unit 150 inputs image information and sensing information to an artificial neural network which learns image information about snow, sensing information about snow, image information about rain, and sensing information about rain as learning data to output the state of the precipitation and may determine whether it is snow or rain based on the output state of precipitation.
For example, the artificial intelligence-based learning model may be generated by artificial intelligence based learning such as machine learning or deep learning, but is not limited thereto and may be applied to various neural network systems which have been already developed or will be developed in the future.
According to the exemplary embodiment of the present disclosure, when the state of the precipitation is snow, the determining unit 150 may determine the state of snow as one of dry snow and wet snow.
For example, when the sensed state of the precipitation is snow, the determining unit 150 may determine whether the state of snow is dry snow or wet snow based on at least one of the image information, the sensing information, and the information received from the external server 300.
As another example, when the sensed state of the precipitation is snow, the determining unit 150 inputs image information of snow and sensing information of snow to an artificial neural network which learns image information of dry snow, sensing information of the dry snow, image information of wet snow, and sensing information of the wet snow as learning data to output information about the state of snow and may determine the sensed state of snow as any one of dry snow and wet snow based on the output information about the state of snow.
For example, the artificial intelligence-based learning model may be generated by artificial intelligence based learning such as machine learning or deep learning, but is not limited thereto and may be applied to various neural network systems which have been already developed or will be developed in the future.
As another example, when this apparatus 100 senses the precipitation and a location altitude of this apparatus 100 is less than a predetermined height above sea level, the determining unit 150 may determine the state of the precipitation as any one of dry snow, wet snow, and rain based on predetermined reference standard deviation information of a thickness value corresponding to location information of this apparatus 100.
As another example, the determining unit 150 substitutes the state of precipitation, temperature information, and relative humidity information into a predetermined determination graph to determine the state of the precipitation as any one of dry snow, wet snow, and rain and may display a coordinate of the state of precipitation to be determined which is located on the determination graph and the determined state information of precipitation on an interface provided to the user terminal 200.
According to the exemplary embodiment of the present disclosure, the calculating unit 160 may calculate at least one of a snow density and a water equivalent ratio based on the precipitation amount and the snowfall amount.
For example, the calculating unit 160 computes a precipitation amount in a predetermined time zone and a snowfall amount in a predetermined time zone with a predetermined equation to calculate at least one of a snow density of the predetermined time zone and a water equivalent ratio of the predetermined time zone.
As another example, the calculating unit 160 provides the precipitation amount and the snowfall to the interface provided to the user terminal 200 as primary outputs and provides the snow density and the water equivalent ratio as secondary outputs corresponding to the primary outputs and may provide causality information between the primary output and the secondary output.
According to the exemplary embodiment of the present disclosure, the determining unit 150 may determine the state of snow as any one of dry snow and wet snow based on the snow density and the water equivalent ratio.
For example, when the snow density in the predetermined time zone is equal to or higher than a predetermined threshold snow density, the determining unit 150 determines the state of snow corresponding to the snow density in the predetermined time zone as wet snow. Further, when the water equivalent ratio in the predetermined time zone is equal to or higher than a predetermined threshold water equivalent ratio, the determining unit 150 may determine the state of snow corresponding to the water equivalent ratio in the predetermined time zone as dry snow which is heavy snow having a predetermined snowfall amount per unit time or more.
According to the exemplary embodiment of the present disclosure, the calculating unit 160 may calculate expected snowfall amount information based on the water equivalent ratio.
For example, the calculating unit 160 calculates an expected precipitation amount by inputting a ground temperature and a temperature at a specific barometric altitude in a region within a predetermined radius from the location information of this apparatus 100 to an artificial neural network which learns a temperature at the specific barometric altitude, the ground temperature, and actual precipitation amount as learning data and may calculate the predicted snowfall information by calculating the calculated expected precipitation amount and the calculated water equivalent ratio with a predetermined equation.
For example, the artificial intelligence-based learning model may be generated by artificial intelligence based learning such as machine learning or deep learning, but is not limited thereto and may be applied to various neural network systems which have been already developed or will be developed in the future.
According to the exemplary embodiment of the present disclosure, the calculating unit 160 may calculate error information based on the expected snowfall amount information and the snowfall amount.
For example, the calculating unit 160 outputs expected actual snowfall information and error information by inputting the calculated expected snowfall information to a first error artificial neural network which learns expected snowfall information, actual snowfall information corresponding to the expected snowfall information, and error information as a learning dataset and may provide the error information to the interface provided to the user terminal 200. Further, the calculating unit 160 may allow a second error artificial neural network to learn the expected actual snowfall information, the output error information, and the actual snowfall information as a learning dataset.
For example, the artificial intelligence-based learning model may be generated by artificial intelligence based learning such as machine learning or deep learning, but is not limited thereto and may be applied to various neural network systems which have been already developed or will be developed in the future.
According to the exemplary embodiment of the present disclosure, the calculating unit 160 may apply error information to calculate the expected snowfall amount information.
For example, the calculating unit 160 inputs the expected snowfall amount information and the error information output by inputting the expected snowfall amount information to the first error artificial neural network to the second error artificial neural network to calculate a final expected snowfall amount information.
According to the exemplary embodiment of the present disclosure, when a wet-bulb temperature is equal to or higher than a predetermined threshold wet-bulb temperature, the control unit 140 may measure the precipitation using the precipitation gauge 111.
For example, during the rainfall observation, when this apparatus 100 determines that the snowfall has occurred or the snowfall will occur within a predetermined time so that the control unit 140 ends rainfall observation, an observation time determining unit 130 stops a remaining rainfall observation time, and then when a wet-bulb temperature of a periphery of this apparatus 100 is equal to or higher than a threshold wet-bulb temperature and the rainfall is sensed, the observation time determining unit 130 may resume the rainfall observation with the remaining rainfall observation time at the time when it was stopped.
According to the exemplary embodiment of the present disclosure, when a wet-bulb temperature is lower than the threshold wet-bulb temperature, the control unit 140 may measure the precipitation using the snowfall amount measurement apparatus.
For example, during the snowfall observation, when this apparatus 100 determines that the rainfall has occurred or the rainfall will occur within a predetermined time so that the control unit 140 ends snowfall observation, an observation time determining unit 130 stops a remaining snowfall observation time, and then when a wet-bulb temperature of a periphery of this apparatus 100 is lower than a threshold wet-bulb temperature and the snowfall is sensed, the observation time determining unit 130 may resume the snowfall observation with the remaining snowfall observation time at the time when it was stopped. The snowfall observation apparatus may include a camera sensor 113 for observing snowfall, a ruler 114 for observing-> measuring the snowfall, and a snowfall removal member 115. When the snowfall observation apparatus is used, it may mean that at least one of the camera sensor 113 for observing snowfall and the snowfall removal member 115 is used.

According to the exemplary embodiment of the present disclosure, each of a plurality of precipitation gauges 111 may include a lid 111b which is open/closed by the control, and a drain 111c.
For example, the plurality of precipitation gauges 111 includes precipitation sensing sensors 111a and when the precipitation sensing sensor 111a senses the precipitation, the control unit 140 may control the precipitation gauge 111 to be open by horizontally rotating the lid 111b around the axis on which the precipitation sensing sensor 111a is provided. When the precipitation gauge 111 is open, the control unit 140 may horizontally rotate the lid 111b in a predetermined direction at a predetermined speed. Further, when a precipitation observation time determined by the observation time determining unit 130 has elapsed after opening the precipitation gauge 111, the control unit 140 may control the precipitation gauge 111 to be closed by horizontally rotating the lid 111b around the axis on which the precipitation sensing sensor 111a is provided. When the precipitation gauge 111 is closed, the control unit 140 may horizontally rotate the lid 111b in a predetermined direction at a predetermined speed. Further, after opening the precipitation gauge 111, even though there is a precipitation observation time determined by the observation time determining unit 130, if the precipitation observation ends, the control unit 140 may control the precipitation gauge 111 to be closed by horizontally rotating the lid 111b around the axis on which the precipitation sensing sensor 111a is provided.
Further, this apparatus 100 measures the precipitation in the precipitation gauge 111 to acquire a precipitation amount.
Further, after acquiring the precipitation amount by this apparatus 100, the control unit 140 controls the drain 111c to drain the precipitation in the precipitation gauge 111 at a predetermined drainage rate per unit time.
Further, at least one drain 111c may be provided in the precipitation gauge 111. Further, the drain 111c may be open or closed by the control of the control unit 140 and a diameter to be open and closed may be also adjusted.
Further, the precipitation gauge 111 may include a member which increases an internal pressure by the control of the control unit 140.
According to the exemplary embodiment of the present disclosure, the lid 111b may be provided on a top of the precipitation gauge 111.
For example, the lid 111b provided on the top of the precipitation gauge 111 horizontally rotates around the axis on which the precipitation sensing sensor 111a is located in the predetermined direction at the predetermined speed by the control of the control unit 140. In this case, when an error level between direction information and speed information included in a control instruction and actual direction information and actual speed information of the actual horizontal rotation of the lid 111b is equal to or larger than a predetermined level, the control unit 140 ends the observation and the moving unit 120 controls the movement member 112 to move this apparatus 100 from a second location to a first location. This apparatus 100 transmits a repair necessary notification of the lid 111b to the user terminal 200 and may transmit repair request information to a repair company terminal. The repair request information may include information about an estimated abnormal part of the lid 111b and a request deadline.
According to the exemplary embodiment of the present disclosure, the drain 111c may be provided on the bottom of the precipitation gauge 111.
For example, the drain 111c provided on the bottom of the precipitation gauge 111 drains the precipitation in the precipitation gauge 111 at a predetermined drainage rate per unit time by the control of the control unit 140. In this case, when an error level between drainage information per unit time included in a control instruction and actual drainage information per unit time of the drain 111c is equal to or larger than a predetermined level, the control unit 140 ends the drainage and the moving unit 120 controls the movement member 112 to move this apparatus 100 from the second location to the first location. This apparatus 100 transmits a repair necessary notification of the drain 111c to the user terminal 200 and may transmit repair request information to a repair company terminal. The repair request information may include information about an estimated abnormal part of the drain 111c and a request deadline.
According to the exemplary embodiment of the present disclosure, the control unit 140 may open the lid 111b for a predetermined precipitation observation time.
For example, during the precipitation observation time, the control unit 140 controls the lid 111b on the top of the precipitation gauge 111 in an open state and may control the drain 111c in a closed state.
As another example, the control unit 140 controls the lid 111b of the precipitation gauge 111 to be open and controls the drain 111c to be open, during the precipitation observation time, so that the precipitation is drained within a predetermine time after being accommodated in the precipitation gauge 111. When the precipitation is in contact with the precipitation gauge 111, this apparatus 100 acquires a precipitation amount per unit time by considering an intensity of the precipitation per unit time and a weight of precipitation sensed at the time of contact and may calculate the precipitation amount by considering the precipitation amount per unit time and the precipitation observation time.
According to the exemplary embodiment of the present disclosure, the control unit 140 may close the lid 111b after the precipitation observation time has elapsed.
For example, when the lid 111b on the top of the precipitation gauge 111 is closed, this apparatus 100 measures the precipitation in the precipitation gauge 111 to acquire the precipitation amount and then the control unit 140 may control the drain 111c to be open.
As another example, when the precipitation observation time has elapsed and the rainfall and the snowfall are not sensed after the precipitation amount measurement, the control unit 140 may control the lid 111b and the drain 111c to be open until a humidity in the precipitation gauge 111 becomes lower than a predetermined level. When the precipitation is not observed, this apparatus 100 opens the lid 111b and the drain 111c of the precipitation gauge 111 in a climate in which the rainfall and the snowfall do not occur to increase an evaporation rate in the precipitation gauge 111. By doing this, an accuracy of the precipitation measurement amount at the time of measuring the precipitation amount using the precipitation gauge 111 may be increased in the future.
Referring to
According to the exemplary embodiment of the present disclosure, when a water level of a first precipitation gauge 111 exceeds a predetermined threshold water level before ending the precipitation observation time, the control unit 140 may control a lid 111b of the first precipitation gauge 111 to be closed and a lid 111b of a second precipitation gauge 111 to be open.
For example, the first precipitation gauge 111 includes at least one precipitation gauge 111 and the second precipitation gauge 111 may include at least one precipitation gauge 111 other than the first precipitation gauge 111. The control unit 140 may set a plurality of precipitation gauges 111 which is symmetric to each other with respect to the bottom plate 110 as the first precipitation gauge 111 and the second precipitation gauge 111. As the control unit 140 sets a plurality of precipitation gauges 111 which is symmetric to each other with respect to the bottom plate 110 as the first precipitation gauge 111 and the second precipitation gauge 111 so that the operation of this apparatus 100 by the moving unit 120 while accommodating the precipitation is stably performed.
As another example, the control unit 140 may set an opening/closing speed of the drain 111c of the first precipitation gauge 111 and an opening/closing timing and opening/closing speeds of the lid 111b and the drain 111c of the second precipitation gauge 111 and opening/closing timings of the lid 111b and the drain 111c of the second precipitation gauge 111 based on at least one of an opening/closing speed of the lid 111b of the first precipitation gauge 111 and the opening/closing timing. For example, the control unit 140 sets an opening speed of the lid 111b of the first precipitation gauge 111 and a closing speed of the lid 111b of the second precipitation gauge 111 to be equal and may set a closing speed of the lid 111b of the first precipitation gauge 111 and an opening speed of the lid 111b of the second precipitation gauge 111 to be equal. Further, when this apparatus 100 senses the precipitation, but does not end the precipitation observation, the control unit 140 controls to start closing the lid 111b of the first precipitation gauge 111 at a time when the precipitation in the first precipitation gauge 111 exceeds the threshold water level after opening the lid 111b of the first precipitation gauge 111 and may control to start opening the lid 111b of the second precipitation gauge 111 at a time when the precipitation in the first precipitation gauge 111 exceeds the threshold water level after opening the lid 111b of the first precipitation gauge 111.

According to the exemplary embodiment of the present disclosure, when a precipitation amount per unit time is equal to or larger than a predetermined level, the observation time determining unit 130 may reduce the precipitation observation time by a predetermined level.
For example, during the rainfall observation, when a precipitation amount per unit time within a predetermined radius of this apparatus 100 is increased to be equal to or larger than a first threshold precipitation amount per unit time, the observation time determining unit 130 may reduce the remaining precipitation observation time at a predetermined first rate. For example, when it is assumed that the first threshold precipitation amount per unit time is 7 mm/h, the precipitation amount per unit time is increased from 5 mm/h to 8 mm/h during the precipitation observation, a remaining precipitation observation time at the time when the precipitation amount per unit time is 7 mm/h is 10 minutes, and the first rate is 90%, the observation time determining unit 130 may reduce the remaining precipitation observation time from 10 minutes to 9 minutes which is 90% of 10 minutes at the time when the precipitation amount per unit time is 7 mm/h which is the first threshold precipitation amount per unit time. Further, the first threshold precipitation amount per unit time may include at least one of a first threshold rainfall amount per unit time and a first threshold snowfall amount per unit time. Further, during the rainfall observation, when a rainfall amount per unit time within a predetermined radius of this apparatus 100 is increased to be equal to or larger than a predetermined first threshold rainfall amount per unit time included in the first threshold precipitation amount per unit time, the observation time determining unit 130 may reduce the remaining rainfall observation time at a predetermined a-th rate included in the first rate. Further, during the snowfall observation, when a snowfall amount per unit time within a predetermined radius of this apparatus 100 is increased to be equal to or larger than a predetermined first threshold snowfall amount per unit time included in the first threshold precipitation amount per unit time, the observation time determining unit 130 may reduce the remaining snowfall observation time at a predetermined A-th rate included in the first rate.
In contrast, during the rainfall observation, when a precipitation amount per unit time within a predetermined radius of this apparatus 100 is reduced to be smaller than the first threshold precipitation amount per unit time, the observation time determining unit 130 may increase the remaining precipitation observation time by the reciprocal of a predetermined first rate. For example, when it is assumed that the first threshold precipitation amount per unit time is 11 mm/h, the precipitation amount per unit time falls from 12 mm/h to 10 mm/h during the precipitation observation, a remaining precipitation observation time at the time when the threshold precipitation amount per unit time is less than 10 mm/h is 8 minutes, and the first rate is 50%, the observation time determining unit 130 may increase the remaining precipitation observation time from 8 minutes to 12 minutes which is 150% of 8 minutes at the time when the precipitation amount per unit time is less than 10 mm/h which is the first threshold precipitation amount per unit time. Further, during the rainfall observation, when a rainfall amount per unit time within a predetermined radius of this apparatus 100 is reduced to be less than the first threshold rainfall amount per unit time, the observation time determining unit 130 may increase the remaining rainfall observation time by the reciprocal of an a-th rate. Further, during the snowfall observation, when a snowfall amount per unit time within a predetermined radius of this apparatus 100 is reduced to be less than the first threshold snowfall amount per unit time, the observation time determining unit 130 may increase the remaining snowfall observation time by the reciprocal of an A-th rate.
As another example, the observation time determining unit 130 may set a first threshold unit precipitation amount, a first rate corresponding to the first threshold unit precipitation amount, a n-th threshold unit precipitation amount, and a n-th rate corresponding to the n-th threshold unit precipitation amount. n may be a positive integer of 2 or larger.
According to the exemplary embodiment of the present disclosure, when the snowfall is sensed during the rainfall observation, the control unit 140 mat end the rainfall observation.
For example, when this apparatus 100 senses the snowfall while observing the rainfall, the control unit 140 ends the rainfall observation. However, after stopping the remaining rain observation time, when the snowfall which has been sensed is not sensed, but the rainfall is sensed, the observation time determining unit 130 may resume the rainfall observation with the remaining rain observation time at the time when it was stopped. Further, when this apparatus 100 senses the rainfall while observing the snowfall, the control unit 140 ends the snowfall observation. However, after stopping the remaining snowfall observation time, when the rainfall which has been sensed is not sensed, but the snowfall is sensed, the observation time determining unit 130 may resume the snowfall observation with the remaining snowfall observation time at the time when it was stopped.
As another example, during the rainfall observation of this apparatus 100, when this apparatus 100 receives information indicating that a freezing altitude is located below a predetermined altitude from the ground surface within a predetermined radius with respect to this apparatus 100 from the external server 300, this apparatus 100 determines that the snowfall has occurred or will occur within a predetermined time and the control unit 140 of this apparatus 100 may end the rainfall observation. When this apparatus 100 senses the snowfall during the rainfall observation to end the rainfall observation, the observation time determining unit 130 stops the remaining rainfall observation time and then this apparatus 100 receives the information indicating that a freezing altitude is located at a predetermined altitude or higher from the ground surface within a predetermined radius with respect to this apparatus 100 from the external server 300 and senses the rainfall, the observation time determining unit 130 may resume the rainfall observation with the remaining rainfall observation time at the time when it was stopped.

According to the exemplary embodiment of the present disclosure, when a water equivalent ratio is equal to or higher than a predetermined level, the control unit 140 may end the rainfall observation.
As an example, during the rainfall observation of this apparatus 100, when a water equivalent ratio for a peripheral atmosphere of this apparatus 100 is equal to or higher than a predetermined level, this apparatus 100 determines that the snowfall has occurred, or the snowfall will occur within a predetermined time and the control unit 140 of this apparatus 100 may end the rainfall observation.

According to the exemplary embodiment of the present disclosure, when a snow density is lower than a predetermined level, the control unit 140 may end the rainfall observation.
For example, during the rainfall observation of this apparatus 100, when a snow density for a peripheral atmosphere of this apparatus 100 is lower than a predetermined level, this apparatus 100 determines that the snowfall has occurred, or the snowfall will occur within a predetermined time and the control unit 140 of this apparatus 100 may end the rainfall observation.

For example, when this apparatus 100 determines that the snowfall has occurred or the snowfall will occur within a predetermined time, it may be the same meaning as the sensing of the snowfall. In contrast, when this apparatus 100 determines that the rainfall has occurred or the rainfall will occur within a predetermined time, it may be the same meaning as the sensing of the rainfall.
According to the exemplary embodiment of the present disclosure, each of a plurality of precipitation gauges 111 may include a lid 111b which is opened/closed under the control, and a drain 111c.
For example, the plurality of precipitation gauges 111 includes precipitation sensing sensors 111a and when the precipitation sensing sensor 111a senses the precipitation, the control unit 140 controls the precipitation gauge 111 to be open by horizontally rotating the lid 111b around the axis on which the precipitation sensing sensor 111a is provided. When the precipitation gauge 111 is open, the control unit 140 may horizontally rotate the lid 111b in a predetermined direction at a predetermined speed. When a precipitation observation time determined by the observation time determining unit 130 has elapsed after opening the precipitation gauge 111, the control unit 140 may control the precipitation gauge 111 to be closed by horizontally rotating the lid 111b around the axis on which the precipitation sensing sensor 111a is provided. When the precipitation gauge 111 is closed, the control unit 140 may horizontally rotate the lid 111b in a predetermined direction at a predetermined speed. Further, after opening the precipitation gauge 111, even though there is a precipitation observation time determined by the observation time determining unit 130, if the precipitation observation ends, the control unit 140 may control the precipitation gauge 111 to be closed by horizontally rotating the lid 111b around the axis on which the precipitation sensing sensor 111a is provided.
Further, this apparatus 100 measures the precipitation in the precipitation gauge 111 to acquire a precipitation amount.
Further, after acquiring the precipitation amount of this apparatus 100, the control unit 140 controls the drain 111c to drain the precipitation in the precipitation gauge 111 at a predetermined drainage rate per unit time. Here, when this apparatus 100 acquires a precipitation amount, it may mean that this apparatus 100 senses the precipitation in the precipitation gauge 111 to calculate the precipitation amount.
Further, at least one drain 111c may be provided in the precipitation gauge 111. Further, the drain 111c is open or closed under the control and a diameter to be open and closed may be also adjusted.
Further, the precipitation gauge 111 may include a member which increases an internal pressure under the control. The precipitation gauge 111 raises a pressure in the precipitation gauge 111 to be equal to or higher than a predetermined level using a member which increases the internal pressure by the control, while draining the precipitation, to increase a precipitation discharging speed.
According to the exemplary embodiment of the present disclosure, the lid 111b may be provided on the top of the precipitation gauge 111.
For example, the lid 111b provided on the top of the precipitation gauge 111 horizontally rotates around the axis on which the precipitation sensing sensor 111a is located in the predetermined direction at the predetermined speed by the control of the control unit 140. In this case, when an error level between direction information and speed information included in a control instruction and actual direction information and actual speed information of the actual horizontal rotation of the lid 111b is equal to or larger than a predetermined level, the control unit 140 stops the observation and the moving unit 120 controls the movement member 112 to move this apparatus 100 from a second location to a first location. This apparatus 100 transmits a repair necessary notification of the lid 111b to the user terminal 200 and may transmit repair request information to a repair company terminal. The repair request information may include information about an estimated abnormal part of the lid 111b and a request deadline.
According to the exemplary embodiment of the present disclosure, the drain 111c may be provided on the bottom of the precipitation gauge 111.
For example, the drain 111c provided on the bottom of the precipitation gauge 111 drains the precipitation in the precipitation gauge 111 at a predetermined drainage rate per unit time by the control of the control unit 140. In this case, when an error level between drainage information per unit time included in a control instruction and actual drainage information per unit time of the drain 111c is equal to or larger than a predetermined level, the control unit 140 stops the drainage and the moving unit 120 controls the movement member 112 to move this apparatus 100 from the second location to the first location. This apparatus 100 transmits a repair necessary notification of the drain 111c to the user terminal 200 and may transmit repair request information to a repair company terminal. The repair request information may include information about an estimated abnormal part of the drain 111c and a request deadline.
According to the exemplary embodiment of the present disclosure, the control unit 140 may open the lid 111b for a precipitation observation time.
For example, during the precipitation observation time, the control unit 140 controls the lid 111b on the top of the precipitation gauge 111 in an open state and may control the drain 111c in a closed state.
As another example, the control unit 140 controls the lid 111b of the precipitation gauge 111 to be open and controls the drain 111c to be open, during the precipitation observation time, so that the precipitation is drained within a predetermine time after being accommodated in the precipitation gauge 111. When the precipitation is in contact with the precipitation gauge 111, this apparatus 100 acquires a precipitation amount per unit time by considering an intensity of the precipitation per unit time and a weight of precipitation sensed at the time of contact and may calculate the precipitation amount by considering the precipitation amount per unit time and the precipitation observation time.
According to the exemplary embodiment of the present disclosure, the control unit 140 may close the lid 111b after the predetermined precipitation observation time has elapsed.
For example, when the lid 111b on the top of the precipitation gauge 111 is closed, this apparatus 100 measures the precipitation in the precipitation gauge 111 to acquire the precipitation amount and then the control unit 140 may control the drain 111c to be open.
As another example, when the precipitation observation time has elapsed and the rainfall and the snowfall are not sensed after the precipitation amount measurement, the control unit 140 may control the lid 111b and the drain 111c to be in the open states until a humidity in the precipitation gauge 111 becomes lower than a predetermined level. When the precipitation is not observed, this apparatus 100 opens the lid 111b and the drain 111c of the precipitation gauge 111 in a climate in which the rainfall and the snowfall do not occur to increase an evaporation rate in the precipitation gauge 111. By doing this, an accuracy of the precipitation measurement amount at the time of measuring the precipitation amount using the precipitation gauge 111 may be increased in the future.
According to the exemplary embodiment of the present disclosure, when a water level of a first precipitation gauge 111 exceeds a predetermined threshold water level before ending the precipitation observation time, the control unit 140 closes a lid 111b of the first precipitation gauge 111 and may open a lid 111b of a second precipitation gauge 111.
For example, the first precipitation gauge 111 includes at least one precipitation gauge 111 and the second precipitation gauge 111 may include at least one precipitation gauge 111 other than the first precipitation gauge 111. The control unit 140 may set a plurality of precipitation gauges 111 which is symmetric to each other with respect to the bottom plate 110 as the first precipitation gauge 111 and the second precipitation gauge 111. As the control unit 140 sets a plurality of precipitation gauges 111 which is symmetric to each other with respect to the bottom plate 110 as the first precipitation gauge 111 and the second precipitation gauge 111 so that the operation of this apparatus 100 by the moving unit 120 while accommodating the precipitation is stably performed.
As another example, the control unit 140 may set an opening/closing speed of the drain 111c of the first precipitation gauge 111 and an opening/closing timing and opening/closing speeds of the lid 111b and the drain 111c of the second precipitation gauge 111 and opening/closing timings of the lid 111b and the drain 111c of the second precipitation gauge 111 based on at least one of an opening/closing speed of the lid 111b of the first precipitation gauge 111 and the opening/closing timing. For example, the control unit 140 sets an opening speed of the lid 111b of the first precipitation gauge 111 and a closing speed of the lid 111b of the second precipitation gauge 111 to be equal and may set a closing speed of the lid 111b of the first precipitation gauge 111 and an opening speed of the lid 111b of the second precipitation gauge 111 to be equal. Further, when this apparatus 100 senses the precipitation, but does not end the precipitation observation, the control unit 140 controls to start closing the lid 111b of the first precipitation gauge 111 at a time when the precipitation in the first precipitation gauge 111 exceeds the threshold water level after opening the lid 111b of the first precipitation gauge 111 and may control to start opening the lid 111b of the second precipitation gauge 111 at a time when the precipitation in the first precipitation gauge 111 exceeds the threshold water level after opening the lid 111b of the first precipitation gauge 111. Further, when this apparatus 100 senses the precipitation, but does not end the precipitation observation, the control unit 140 controls to start closing the lid 111b of the second precipitation gauge 111 at a time when the precipitation in the second precipitation gauge 111 exceeds the threshold water level after opening the lid 111b of the second precipitation gauge 111 and may control to start opening the lid 111b of the first precipitation gauge 111 at a time when the precipitation in the second precipitation gauge 111 exceeds the threshold water level after opening the lid 111b of the second precipitation gauge 111.
According to the exemplary embodiment of the present disclosure, when the lid 111b of the precipitation gauge 111 is closed or the observation ends, the control unit 140 senses the precipitation in the precipitation gauge 111 and then opens the drain 111c to discharge the precipitation.
For example, after closing the lid 111b of the first precipitation gauge 111, the control unit 140 senses the precipitation in the precipitation gauge 111 and then controls to start opening the drain 111c of the first precipitation gauge 111. In this case, the drainage amount per unit time of the first precipitation gauge 111 may be set such that a precipitation decrease rate in the first precipitation gauge 111 is larger than a precipitation increase rate in the second precipitation gauge 111. Further, after closing the lid 111b of the second precipitation gauge 111, the control unit 140 senses the precipitation in the second precipitation gauge 111 and then controls to start opening the drain 111c of the second precipitation gauge 111. In this case, the drainage amount per unit time of the second precipitation gauge 111 may be set such that a precipitation decrease rate in the second precipitation gauge 111 is larger than a precipitation increase rate in the first precipitation gauge 111. In order to increase the drainage amount per unit time, the control unit 140 selectively controls a plurality of drains 111c provided in the precipitation gauge 111, increases an opening diameter of the drain 111c, or may increase a pressure in the precipitation gauge 111.
According to the exemplary embodiment of the present disclosure, when the foreign material is sensed in the precipitation gauge 111 whose lid 111b is open, the control unit 140 controls the air-blow 111d provided in the precipitation gauge 111 to discharge the foreign material to the outside.
For example, a plurality of sensors is provided in the precipitation gauge 111. When this apparatus 100 senses foreign materials in the precipitation gauge 111 whose lid 111b is open based on the sensing information, the control unit 140 selectively controls an air-blow 111d whose nozzle is not immersed in the precipitation, among a plurality of air-blows 111d provided in the precipitation gauge 111, to spray air with a predetermined spray intensity until the foreign materials are discharged to the outside of the precipitation gauge 111, based on at least one of image information and sensing information. Further, when this apparatus 100 senses that foreign materials enter the precipitation gauge 111 based on the image information generated by the camera sensor 113 which captures the precipitation gauge 111, the control unit 140 selectively controls an air-blow 111d whose nozzle is not immersed in the precipitation, among a plurality of air-blows 111d provided in the precipitation gauge 111, to spray air with a predetermined spray intensity until the foreign materials are discharged to the outside of the precipitation gauge 111, based on at least one of image information and sensing information.
As another example, when the precipitation observation time has elapsed and the rainfall or the snowfall is not sensed after measuring the precipitation amount, the control unit 140 controls the lid 111b and the drain 111c to be open until the humidity in the precipitation gauge 111 becomes lower than a predetermined level, based on the sensing information in the precipitation gauge 111 and controls the air-blow 111d provided in the precipitation gauge 111 to spray air with a predetermined spray intensity until the humidity in the precipitation gauge 111 becomes lower than a predetermined level, based on the sensing information in the precipitation gauge 111. When the precipitation is not observed, this apparatus 100 opens the lid 111b and the drain 111c of the precipitation gauge 111 and operates the air-blow 111d in a climate in which the rainfall and the snowfall do not occur to increase an evaporation rate in the precipitation gauge 111. By doing this, an accuracy of the precipitation measurement amount at the time of measuring the precipitation amount using the precipitation gauge 111 may be increased in the future.
According to the exemplary embodiment of the present disclosure, when the temperature in the precipitation gauge 111 is lower than a predetermined threshold temperature, the control unit 140 controls a heater provided in the precipitation gauge 111 to increase the temperature in the precipitation gauge 111 to be equal to or higher than a threshold temperature.
For example, when the temperature in the precipitation gauge 111 is lower than the predetermined threshold temperature based on the sensing information, the control unit 140 may control the heater provided in the precipitation gauge 111 to apply heat with a predetermined intensity to the precipitation gauge 111 until the temperature in the precipitation gauge 111 becomes equal to or higher than the threshold temperature, based on the sensing information.
As another example, when the precipitation observation time has elapsed and the rainfall or the snowfall is not sensed after measuring the precipitation amount, the control unit 140 controls the lid 111b and the drain 111c to be open until the humidity in the precipitation gauge 111 becomes lower than a predetermined level, based on the sensing information in the precipitation gauge 111, controls the air-blow 111d provided in the precipitation gauge 111 to spray air with a predetermined spray intensity until the humidity in the precipitation gauge 111 becomes lower than a predetermined level, based on the sensing information in the precipitation gauge 111, controls the heater provided in the precipitation gauge 111 to apply heat with a predetermined intensity to the precipitation gauge 111 until the humidity in the precipitation gauge 111 becomes lower than a predetermined level, based on the sensing information in the precipitation gauge 111. When the precipitation is not observed, this apparatus 100 opens the lid 111b and the drain 111c of the precipitation gauge 111 and operates the air-blow 111d and heater in a climate in which the rainfall and the snowfall do not occur to increase an evaporation rate in the precipitation gauge 111. By doing this, an accuracy of the precipitation measurement amount at the time of measuring the precipitation amount using the precipitation gauge 111 may be increased in the future.
