JPS62218824A - Measuring apparatus for weather condition-wise heavenly body element - Google Patents

Abstract

PURPOSE:To eliminate the need for a sophisticated adjustment, by setting a shading belt rotatably on a model heavenly body as semi-arc strip to intercept light to a passive sensing section while the passive sensing section is fixed horizontally on a support in the form of an actinometer, an illumination photometer or the like. CONSTITUTION:A rotating shaft 4 of a rotary (mobile) type shade belt 2 is set on a support member 14 and a motor 5 for rotation is provided to rotate it at a fixed speed. To keep a passive sensing section 1 horizontal, a leveller 8 is mounted inside the body and to keep the whole equipment horizontal, an exhaust port 13 is provided on a cover lid 6. An electric signal obtained at the passive sensing section 1 is recorded on a recorder according to an electric code 10. In a fine weather, the total heaven illuminance indicates the upper limit value 31 while the heaven illuminance indicates the lower limit value 32. Thereby, when the sun is covered with a cloud during the daytime, the shading effect does not exist and the result is a decrease in the difference between the upper and lower limit data values thus enabling the identification of the condition as cloudy. In this case, there is no need for a sophisticated adjustment as required for a stationary shading belt.

Description

[Detailed Description of the Invention] (a) Industrial Application Field This invention provides the following advantages: By rotating (moving) the shade belt,
- It is possible to perform the following three types of measurements with a single sensing part, that is, to create and measure the entire sky and the state of the sky, and in addition, by measuring this continuously, it is possible to compare the differences before and after. The entire sky, which allows you to distinguish between clear and cloudy,
The present invention relates to a weather-specific sky element measuring device that can measure the sky and clear and cloudy conditions.

(b) Conventional technology Conventionally, all-sky illuminometers and pyranometers, as well as sky illuminometers and pyranometers, exist as individual measuring instruments. Furthermore, in the case of the sky, it was necessary to adjust the altitude of the sun cover zone 2 every season, and the Gijordan pyranometer is used to measure clear and cloudy conditions, but it does not correspond to the time of day with other measured values. It seems that there are some electrical solar irradiance meters that cannot be obtained with sufficient accuracy, and the response results for clear and cloudy conditions vary seasonally, but this is unclear.

By rotating (moving) the sunshade zone, this invention enables the measurement of two different sky conditions using - number of sensing sections, and furthermore, by continuous measurement, it is also possible to distinguish over time whether it is clear or cloudy during the daytime. It can also be used as a so-called sunlight meter.

(c) Problems to be solved by the invention This invention changes and reproduces the state of the sky elements in the whole sky and the sky by means of a rotating (moving) sunshade belt, and the two different sky phenomena can be experienced by one sensing part. Furthermore, because of the rotating (moving) sun cover strips, traditional fixed sun cover strips require seasonal altitude adjustments, which can be forgotten and result in incorrect data. This problem was eliminated by the rotating (moving) shade belt, which also eliminated the need for altitude adjustment, resulting in improved accuracy. Another purpose is to be able to determine whether it is clear or cloudy during the daytime from a graph obtained by continuously measuring the entire sky and the state of the sky using this device.

(d) Means for solving the problem The device for measuring sky elements by weather is equipped with a sensing part at the center of a hemispherical model celestial body, and for the sensing part, it is necessary to remove the actual sun from the model celestial body. As a sunshade device that does not need to be removed, a sunshade belt in the shape of a semi-circular arc is installed above the model sky in a rotating manner to block light reception to the sensing part, and the sensing part is supported as an illumination meter, pyranometer, etc. Fix it horizontally to the material. The gist includes a rotating mechanism for rotating the shade strip, and a recording device for recording electrical signals output from the sensing section.

(E) Function This invention can be used as necessary to provide a luminometer, a pyranometer, a UV meter,
By making it possible to attach an appropriate sensing section 1, such as a radiation balance meter, as needed, and rotating (moving) the sunshade belt, one sensing section can measure the sky elements in the state of the entire sky (the state of the entire sky on a clear day). (Fig. 4) to the sky state (Fig. 5). On the other hand, on rainy or cloudy days, the sun disappears due to clouds, so the sun-shading effect of the sun-shading belt can be changed. Utilizing this effect, which acts on the sensing section 1 as a phenomenon similar to the state of the sky during clear skies, it is possible to determine whether it is clear and cloudy and to measure the duration of clear and cloudy weather.

(f) Examples An embodiment of the present invention will be described based on the drawings.

In Fig. 1, the sensing part 1 is fixed horizontally, the rotating (movable) type sun cover band 2 is rotated (moved), and the rotating shade band 2 is rotated (moved).
The band is shaped like an arc for stability and durability, and assuming a clear day, the sensor part 1 is completely shaded. If the sensor part 1 is used as an illuminance meter at that time, the value obtained is This is the sky illuminance during clear skies, and on the other hand, the value of the sensor 1 obtained when the rotating (movable) type sunshade band 2 does not appear completely above the sky is the total sky illuminance, which is the sky illuminance when the sky is in a continuous state of O or higher. In order to reproduce this alternately, the rotating shaft 4 of the rotary (movable) sunshade band 2 was installed on the support member 14, and a rotating motor 5 was provided to rotate it at a constant speed. A glass dome-like lid 3 is waterproof attached to these devices to transmit sunlight and solar heat, and protect them from wind and rain.To protect the entire device, a lid 6 that covers the device can be opened and closed. Hinge 1 for opening and closing cover lid 6
1 was attached, and a fixing fitting 12 was attached to fix the device cover lid 6. A spirit level 8 is installed inside the main body to keep the sensing part 1 horizontal, and a device horizontal adjustment screw 7 is provided to keep the entire device horizontal. In order to avoid high temperatures inside the main body due to solar heat, a blower fan 9 is provided, and an exhaust port 13 is provided on the device cover 6.

The electrical signal obtained from the sensing unit 1 is recorded in the recording device through the electrical cord 10, and as shown in FIG. 6, when the weather is clear, the total sky illuminance shows an upper limit of 31, and the sky illuminance shows a lower limit of 32.
Therefore, when the sun is covered by clouds at noon, the sunshading effect disappears, and as a result, the difference between the upper and lower data values attenuates, so it can be determined that it is cloudy as shown in 33. .

Although the embodiment has been constructed as described above, the present invention is not limited to this. For example, the rotation mechanism may be a one-gear type or a belt type. The sensing part mechanism also includes a sunshine meter, pyranometer, ultraviolet meter,
It can be replaced and measured depending on the purpose, such as a radiation balance meter.

(G) Effects of the Invention As explained above, this invention has − number of sensing parts, and by attaching the rotary (movable) type sunshade band 2 to this, the state of the whole sky and the state of the sky can be determined. The conditions can be reproduced, and illuminance, solar radiation, etc. can be measured by replacing the sensing part. Furthermore, by continuously measuring this during the daytime, it is possible to determine whether it is clear or cloudy. (such as the need to do so),
It is valid.
