Through these automatic weather observation devices, the rainfall, temperature, humidity, And weather data are collected and processed by the server so that the processed data are provided to the customer.

These weather sensors correspond to expensive high-precision micro-electro mechanical systems (MEMS) sensors and are generally composed of one for each measurement item such as rainfall, temperature, humidity and air flow rate. In this case, There is no criterion for judging whether or not the measurement value generated by the sensor is correct, and thus it has been impossible to obtain a correct sensor value for the measurement item.

Therefore, the sensor value generated by these sensors may exceed the error range of the data value required by the Korea Meteorological Administration, resulting in a high reliability of the observation value.

Also, when replacing a faulty sensor with a new one, the continuity between these sensor values is degraded due to errors that have occurred since the replaced sensor itself was produced at the factory, which is an obstacle to data quality improvement.

FIG. 1 shows a configuration of a small automatic weather observation apparatus 100 according to an embodiment of the present invention and a server 200 for managing data transmitted from the apparatus.

The small automatic meteorological observing apparatus (100) of the present invention corresponds to meteorological equipment arranged in various places in each area of the area to measure the weather environment of a specific area, and is fixed or movable to a moving object by a mounting support, And provides the server with the quality measurement value.

In particular, the small automatic meteorological observing apparatus 100 may be attached to a moving object such as a vehicle or a gondola, and may be miniaturized to be attached to a mobile terminal or the like.

1, the small automatic meteorological observing apparatus 100 includes a sensor unit 110, a measured value determining unit 120, a notification unit 130, a GPS module unit 140, a communication module unit 150, And a control unit 160. Here, the small automatic meteorological observing apparatus 100 may essentially include the sensor unit 110 and the measured value determining unit 120.

According to the embodiment of the present invention, the sensor unit 110, the measurement value determination unit 120, the notification unit 130, the GPS module unit 140, the communication module unit 150, Some of which may be program modules that are included in or communicate with the device 100. 1, the sensor unit 110, the measurement value determination unit 120, the notification unit 130, the GPS module unit 140, the communication module unit 150, and the control unit 160 are all connected to the device 100 Are included as examples. At least some of these program modules may be included in the device 100 in the form of an operating system, application program modules, and other program modules, and may be physically stored on various known memory devices. Also, at least some of these program modules may be stored in a remote storage device that is capable of communicating with the device 100. Such program modules include, but are not limited to, routines, subroutines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types as described below in accordance with the present invention.

The sensor unit 110 includes a plurality of types of sensors for generating measurement values for each measurement item for a weather environment such as a wind direction, a wind speed, a temperature, a humidity, an air pressure, an illuminance, At least some types of sensors may each be configured to include a plurality of sensors of the same type. This will be described later in more detail. Here, the measured value corresponds to the wind direction value, the wind speed value, the temperature value, the humidity value, the atmospheric pressure value, the illuminance value, and the like, which sensors corresponding to the measurement item generate by sensing the weather environment.

As shown in FIG. 2, when the measurement items for the weather environment are E1, E2, ..., Ek, ..., En, the sensor unit 110 measures at least A sensor group G1 including at least three sensors for measuring a measurement item Ek, a sensor group G2 including at least three sensors for measuring a measurement item Ek, a sensor group G2 including at least three sensors, And a sensor group Gn including at least three sensors for measuring the item En.

In the present invention, the sensor group G1 includes S11, S12 and S13 as sensors, the sensor group G2 as S21, S22 and S23 as sensors, and the sensor group Gk as Sk1, Sk2, And the sensor group Gn is constituted by sensors Sn1, Sn2, Sn3. However, the present invention is not limited to this, and each sensor group is referred to as a sensor group if it is composed of three or more sensors for the same measurement item, It is not necessary for the number of sensors to match.

The measurement values generated by the sensors included in the specific sensor group at a specific time or a time close to a specific time can be compared with each other by the measurement value determination unit 120. [

The measurement value determination unit 120 relatively compares the measurement values of the sensors included in the specific sensor group to remove the measurement values deviating from the predetermined error range in consideration of the average or standard deviation of the measurement values, Values to be used for statistical processing by acquiring the measurement values and transmitting them to the server 200, which will be described later.

At this time, all the measured values may be obtained if they are within the error range for the average, and all of the measured values may be removed if the standard deviation value of the all measured values becomes large.

Meanwhile, the measurement value determiner 120 may absolutely compare the measurement values of the sensors included in the specific sensor group. In this case, when the temporal change of the measurement values satisfies a preset condition (for example, Or the value does not change during a predetermined time interval, etc.), it is determined that the measurement value is out of the error range, and the measurement value is removed and only the remaining measurement values are acquired And transmitted to the server 200, which will be described later, to be used for statistical processing.

The measurement value determination unit 120 shown in FIG. 1 will be described with reference to FIG. 2. The sensor unit G1 includes at least three sensors S11, S12, and S13 that are out of an error range. The measurement value for the measurement item E1 is obtained with reference to the measurement value except for the measurement value by the sensor group G2 and the measurement by the sensor out of the error range among the at least three sensors S21, S22, S23 included in the sensor group G2 If there is a value, the measurement value for measurement item E2 is obtained with reference to the measured value except for the measurement value.

Likewise, when there is a measurement value of at least three sensors Sk1, Sk2, Sk3 included in the sensor group Gk and deviating from the error range, a measurement value for the measurement item Ek is acquired And when there is a measurement value out of an error range of at least three sensors Sn1, Sn2, Sn3 included in the sensor group Gn, the measurement value for the measurement item En is obtained with reference to the measurement value excluding the measurement value.

On the other hand, if the measurement value deviating from the error range continues to occur for a predetermined period or occurs at a predetermined ratio or more, the sensor may be determined as a failure sensor and replaced with a new sensor. The determining unit 120 compares the measured value obtained by the new sensor with the measured value of the existing sensor, and when the measured values are different from each other, the measured value obtained by the new sensor is compared with the measured value of the existing sensor And can correct by a predetermined value.

That is, the measurement value determination unit 120 compares measurement values of the sensors belonging to the specific sensor group Gk with each other, and when the measured value of the predetermined sensor continuously differs from the measured value of the remaining sensor by a predetermined value or a predetermined ratio or more The sensor that generates the difference measurement value can be determined as the replacement sensor. After the sensor is replaced with the new sensor, the measurement value of the existing sensor belonging to the specific sensor group Gk is used as the reference data, The measured value can be obtained after correcting the measured value.

Here, in the process of replacing the sensor determined as the failure sensor with the new sensor, the notification unit 130 may generate the notification signal so that the sensor detected as the failure can be replaced.

More specifically, if a measurement value out of the error range among the measured values of at least three sensors Sk1, Sk2, Sk3 included in the specific sensor group Gk continues to occur for a predetermined time or exceeds a preset ratio within a predetermined interval The notification unit 130 generates a notification signal for guiding the replacement of the sensor for generating the measurement value out of the error range with respect to the sensor group Gk and provides the notification signal to the user.

Meanwhile, while the measurement value determination unit 120 acquires the measurement values, the location information corresponding to the acquired measurement values may be managed in association with each other or may be transmitted by the server 200 so that the server 200 can manage the corresponding values. For this purpose, the small automatic meteorological observing apparatus 100 according to the present invention may further include a GPS module unit 140 for receiving coordinates information of a current point where the present invention is located from the GPS.

The GPS module 140 transmits the generated position information and the corresponding time information to the measured value determining unit 120. The measured value determining unit 120 obtains the time information at the time when the acquired measured value is generated, And synchronized with the time information transmitted from the module unit 140. For example, when the time at which the measurement value is obtained by the measurement value determination unit 120 and the time at which the GPS module unit 140 acquires the position information is different, the interpolation method ), And the like, and the like.

Meanwhile, the measurement value obtained by the measurement value determination unit 120, the position information corresponding thereto and the synchronized time information may be transmitted to the server 200 by the communication module unit 150. That is, the communication module unit 150 transmits the measurement values of the measurement items E1, E2, ..., En obtained by the measurement value determination unit 120 and the position information and the time information corresponding thereto to the server 200, .

The communication module unit 150 may communicate with the sensor unit 110, the measurement value determination unit 120, the notification unit 130, the GPS module unit 140, the control unit 160, It is possible to perform a function to enable communication.

The present invention is exemplarily described in which the communication module unit 150 communicates with the server 200 wirelessly on the assumption that the small automatic meteorological observing apparatus 100 is attached in a mobile manner. However, the present invention is not limited to this, The communication module unit 150 may be connected to the server 200 by wire while the apparatus 100 is fixedly attached to the facility.

The control unit 160 of the present invention has a function of controlling the flow of data between the sensor unit 110, the measured value determination unit 120, the notification unit 130, the GPS module unit 140, and the communication module unit 150 . That is, the controller 160 according to the present invention controls the flow of data between the components of the server 100 from / to the outside, thereby controlling the flow of data between the sensor unit 110, the measured value determination unit 120, 130, the GPS module unit 140, and the communication module unit 150, respectively.

Meanwhile, as described above, the measurement values of the measurement items obtained by the measurement value determination unit 120 and the corresponding position information and time information are provided to the server 200 through the communication module unit 150 The server 200 generates statistical data or meteorological data for analyzing the meteorological phenomenon, thereby monitoring, analyzing, predicting and controlling the environment.

In particular, the server 200 associates the measured values of the sensor, the corresponding positional information, and the time information on the digital map so that the measured values of the meteorological environment items to be acquired while the small automatic meteorological apparatus 100 moves Supports monitoring by the administrator.

3, when a plurality of miniature automatic weather observation devices 100a, 100b, and 100c are located within a predetermined range of a specific area, the measured values and their corresponding Since the location information and the time information are transmitted to the server 200, the server 200 complements the shadows between the measurement areas by mapping the measured values acquired by moving the small automatic meteoroscopes 100 on the digital map So that it can be processed with more precise meteorological observation data.

When a plurality of miniature automatic meteorological observing apparatuses 100a, 100b and 100c are located within a predetermined range of a specific area, a sensor group for a specific measurement item among a plurality of small meteorological observing apparatuses 100a, 100b, So that the sensors in a particular sensor group of a particular device (e.g., 100a) will be able to detect when two or more failures are preventing the measurements from being obtained properly. That is, when comparing measurements by sensors in a particular sensor group of a particular device (e.g., 100a) with measurements by sensors in a particular sensor group of another device (e.g., 100b, 100c, etc.) For example, when the measurement value of the sensor in the specific sensor group of the sensor 100a is the average value or the standard deviation obtained by the measurement by the sensors in the specific sensor group of the other sensor (for example, 100b, 100c, etc.) It may be possible to notify that the sensor group for measuring a specific measurement item of a specific device (for example, 100a) is a replacement target.
