Next, the external configuration of the weather observation device 2 according to the present embodiment will be described. 3 to 5 are views for explaining an external configuration of the weather observation device 2 according to the present embodiment. More specifically, FIG. 3 is a side view of the weather sensor 21 according to the present embodiment, and FIG. Is a front view, and FIG. 5 is a plan view. Hereinafter, description will be made with reference to these drawings.

In the figure, a housing 31 of the weather observation device 2

The base 32 has a hollow inside, and a fan 38 is provided on a side surface thereof. The fan 38 is for ventilating the air inside the base 32. Thereby, the air inside and outside the base 32 is circulated by the fan 38, and the internal temperature is prevented from rising due to the irradiation of direct sunlight.
The sensor section 33a at the tip of the sensor can measure the temperature of the outside air without being affected by direct sunlight.

The wind speed sensor 34 is provided such that a sensor portion located at the head portion is projected upward by a support portion 34a. The wind speed sensor 34 may be of a three-cup type or a propeller type. However, if it is not necessary to comply with the Meteorological Business Law, there is no moving part and the storage space can be saved. It is preferable to use a mold. In the present embodiment, a hot wire type is adopted. An air pressure sensor 35 is provided below the main body of the wind speed sensor 34 formed by the support portion 34a. The air temperature and the air pressure measured by the air temperature sensor 33 and the air pressure sensor 35 are used as parameters for obtaining the wind speed. For example, if the desired wind speed is V,

[0029]

(Equation 1) Can be indicated by

The rainfall sensor 36 has a circular rainfall port 3
6a is provided. The rain collecting port 36a is formed in a funnel shape, and rainfall is collected by the rain collecting box 36b. The rainfall sensor 36 outputs a predetermined signal every time a fixed amount of collected rainfall is collected. An ultraviolet radiometer 37 is provided above the rain hole 36a by a support 37a. That is, as shown in FIG. 5, the ultraviolet radiometer 37 is placed by the support portion 37a directed from the edge of the rain hole 36a so as to be substantially at the center of the rain hole 36a. Therefore, there are rainfall that is directly collected by the rain collection port 36a and rainfall that reaches the ultraviolet radiometer 37 and is collected along the rainfall. By adopting such a configuration, the initial sensitivity at the beginning of raining is slightly reduced, but the storage ability can be dramatically improved.

The weather observation device 2 integrally formed as described above is installed on a utility pole or other support poles by, for example, a fastener 39 provided on the housing 31.

Next, the information processing section 23 in the weather observation device 2 according to the present embodiment will be described. FIG. 6 is a block diagram illustrating the information processing unit 23 according to the present embodiment.

In FIG. 3, when notified of the date and time designated by the timer 62, the data collecting means 61 collects various data from each of the temperature sensors 22 and, if necessary, collects the collected data. The correction calculation is performed and recorded in the weather data storage unit 63. For example, for the wind speed, as described above, the correction calculation is performed using the temperature and the atmospheric pressure as auxiliary parameters. The browsing data creation unit 64 creates a Web page document based on various weather data recorded in the weather data storage unit, and stores it as a file in a predetermined document root directory on the server 22.

On the other hand, the various weather data collected by the data collection means 61 are simultaneously diagnosed by the diagnosis means 65 as to whether or not they are appropriate values. For this diagnosis, the past data storage means 66 stores the past weather data corresponding to the characteristics of each weather data.

That is, the past temperature data storage means 66a
Is an upper limit value and a lower limit value in consideration of a seasonal factor and a regional factor, for example, an average value of maximum and minimum temperatures of each month in the past 30 years as shown in FIG. I remember. The past temperature data storage unit 66a stores such an upper limit value TMax and a lower limit value Tmin, for example,

[0036]

(Equation 2) Is stored as a mathematical expression indicating an approximate curve as indicated by.

Past wind speed data storage means 66b, past atmospheric pressure data storage means 66c, and past rainfall data storage means 6
Each of 6d stores its maximum and minimum values throughout the year.

Then, the past ultraviolet irradiation data storage means 6
6e stores the upper limit value G and the lower limit value (= 0) by the following formula in consideration of the seasonal factor and the regional factor.

[0039]

(Equation 3) Note that m in the above equation is the path of the atmosphere (Airmass), and based on the date and time (month, day, time) given by the timer 62 and a preset latitude,

[0040]

(Equation 4) Indicated by This past ultraviolet irradiation data storage means 66e
Also stores the solar radiation intensity upper limit value as shown in FIG. This solar radiation intensity upper limit is used for diagnosis based on a correlation with rainfall, which will be described later.

It is preferable that such past weather data can be set, for example, from outside the apparatus via setting means (not shown). As an example of the setting means, Web
A method of setting from a client computer using the CGI function of the server is considered.

Based on the past data stored in the past data storage means 66, the diagnosis means 65 determines whether each collected weather data indicates an abnormal value. That is, the diagnosis unit 65 refers to the past temperature data storage unit 66a for the collected temperature data, and determines whether the collected temperature data is out of the range given by the upper limit value TMax and the lower limit value Tmin obtained by Expression 2. If it is determined to be deviating, it is abnormal (abnormal alarm)
Is output. The diagnosing unit 65 also stores, for each of the collected wind speed data, atmospheric pressure data, and rainfall data, the corresponding past data storage units 66b and 66c.
And 66d, it is determined whether or not the value is out of the range given by the maximum value and the minimum value. If it is determined that the value is out of the range, an error is output. Further, the diagnosis unit 65 determines whether the collected ultraviolet irradiation data exceeds the upper limit G obtained by Expression 3.
Alternatively, it is determined whether or not it is 0 or less, and if it is determined that the value is deviated, an error is output. Furthermore, the diagnostic means 65 detects the correlation between the rainfall data and the UV irradiation data, that is, the UV irradiation data detects a high level value in spite of detecting rainfall according to the rainfall data. If there is, an output indicating that any device is abnormal is output. The abnormality alarm output from the diagnosis unit 65 is sent to, for example, the server 22 and notified to a predetermined computer via a network.

As described above, according to the present embodiment, the various weather sensors are integrally arranged in consideration of their respective characteristics, so that an extremely compact weather observation device can be configured. In particular, the ultraviolet radiometer is formed on the opening of the rainfall sensor, but the rainfall hitting the ultraviolet radiometer is collected without fail as it travels without impeding the measurement. It can be very compact. Therefore, since it can be installed on any utility pole, for example, regardless of the installation location, a large number of measurement points can be secured.

According to the present embodiment, since the weather observation device has a server function, it is possible to freely download the measured weather data using a remote client computer via a network. it can. In particular, by providing a Web server function as in the present embodiment, it is possible to access the weather observation device from a remote client computer and easily browse the weather data.

Further, according to the present embodiment, the weather observation device is provided with a self-diagnosis function, and when an abnormal alarm is output, it is notified to a predetermined computer through a network, so that an abnormality of the device can be immediately detected. You can know. This is particularly effective in terms of maintenance management when the meteorological observation devices are installed at many measurement points.
