DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for observing wind for weather forecasting, which can be easily understood at a glance by showing the movement of the wind in a bird's-eye view.
One is to track a virtual levitation body (balloon) from the instantaneous wind direction and instantaneous wind of the local wind passing through the anemometer and anemometer installed at one point, This is a local wind simulator for displaying or recording a course, and the course can be stored as data as needed. The other is that there is no need to accumulate data over a long period of time, but it can be moved anywhere at any time in case of an accident such as an outbreak of a harmful gas or the like, and can be moved near the source of the harmful gas or the like. The present invention mainly relates to a mobile, local wind observation method and apparatus for observing the movement of the wind around the wind and predicting the diffusion state of harmful gas and the like thereafter.

2. Description of the Related Art At present, large-scale meteorological observation over a wide area, for example, in Japan, AMeDAS (AMeDAS)
= Automated Meteorological
Data Acquisition System)
Rainfall (rain /
A robot that automatically observes the four major elements (snow), temperature, sunshine, wind direction and speed (interval: about 21 km) and a robot that automatically observes only precipitation (interval: about 17 km) are installed.
Data is automatically collected every hour on the telephone line.

[0003] In addition to the above-mentioned automatic observation by AMeDAS, there are also observations made by visual observation. These are cloud cover, cloud shape, cloud condition, current weather, visibility, thunder, yellow sand, and the like.

[0004] Weather observations at sea are performed by marine meteorological observatories or meteorological observation boats, except for those engaged in meteorological observation, and by the World Meteorological Organization (WM).
Many private ships are cooperating with the observation based on the observation method specified in O) and the procedure such as the data transmission method.

[0005] High-level weather observations are performed daily from high-level weather stations.
At the same time, the Lewinsonde is suspended from a meteorological balloon flying at an altitude of about 30 km from the ground. Lewinsonde has sensors for air pressure, temperature, humidity, wind direction, wind speed and a wireless transmitter. The balloon rises while being swept by the wind, but receives observation data while tracking it with a direction finder installed on the ground. The altitude by Lewinsonde is calculated using physical formulas from atmospheric pressure, temperature and humidity. From this altitude, the azimuth angle and the altitude angle obtained by the direction finder, the position of the Lewinsonde can be known, and the wind direction and the wind speed are obtained from the moving direction and the distance. Separately, the air pressure up to about 15 km from the ground, and the wind direction and speed are 2
Observed twice.

[0006] Observations by meteorological rockets can be said to be part of high-level meteorological observations. After launching a small rocket with a Lewinsonde and launching it to an altitude of about 60 km, measure the temperature while lowering the Lewinsonde with a parachute. The wind direction and speed at altitudes of about 20km to 60km are also observed. In Japan, it is held once a week at the Rocket Meteorological Observatory in Iwate Prefecture.

[0007] The observation by the weather radar is performed by emitting a pulse wave of the intensity and distribution of rain and echoing it. In particular, the weather radar installed by the Japan Meteorological Agency on the summit of Mt. Fuji is particularly famous. Recently, a group of private companies including NEC has established a method for identifying the direction of the wind moving clouds by color using radar using the Doppler effect on Izu Oshima.

[0008] The weather observation and the handling of weather information, which were previously under the jurisdiction of government agencies such as weather stations and weather stations, are now open to the private sector. Private companies conduct local or small-scale meteorological observations. Businesses that provide the results as weather forecasts to customers for a fee have begun to take off in various places.

In recent years, not only domestic or general weather information but also international, that is, weather information that transcends borders or for professionals has been required. For example, agricultural information such as yellow sand flying from China to Japan and information about Nikka Moth, a pest of rice cultivation, and the temperature of the water reaching the global scale. The demand for fisheries meteorological information to obtain information on the meandering of the current caused by the El Niño phenomenon and the La Niña phenomenon that causes a drop in water temperature, the resulting fluctuations in catches, and changes in the species of fish caught has also increased. ing. Smaller, for example, to organize excursions such as fishing, golf, athletic meet, excursion, etc., local weather information for lunch sellers who have to determine the number of lunch boxes to prepare, and affect the record at the competition. Local weather information to determine the date and time to avoid the wind to give, for example, the leakage of radioactive gas from factories and the scattering of waste gas and cedar pollen from plants etc.Health maintenance and environmental protection Environmental and sanitary weather information, etc. Recently, information on photochemical smog, which mainly occurs in the center of urban areas, has been given priority, especially for vulnerable school children.

[0010] Local weather information as industrial weather information may be, for example, from a manufacturer of natural salt by sun drying, a processor of marine products, etc., a sowing, fertilization, dispersal of insecticides, a reaping, a natural drying, a natural drying. It is an important guideline for judging the work time even for those who cultivate, cultivate, and process agricultural and forestry products that perform humidification and other operations. In addition, it has become indispensable for conducting surveys to select suitable sites for installing wind power generators.

[0011] However, in the case of a weather forecast for a local area of up to about 10 km square, the minimum required ordinary weather observation equipment is required without flying a very expensive radiosonde every day. For example, in addition to using data that covers the local area and its surroundings accumulated by anemometers, anemometers, barometers, thermometers, hygrometers, rain gauges, etc., radio weather information and weather radio Information from interception and information on weather faxes are referenced.

It has been clarified that the movement, generation, development, shrinkage, and disappearance of dunes are mainly caused by the action of wind for a long period of time. In estimating the location of the buried archeological site,
One of the archeological excavations is to clarify the weather conditions from that time to the present by analyzing icicles collected deep underground in Antarctica.

By the way, the biggest factors of the change of weather are the radiant energy of the sun and the rotation of the earth. Among the weather data, atmospheric pressure, temperature, humidity, wind direction, wind speed, rainfall, and the like can be measured relatively easily.

As described above, as the demand for local weather forecasts related to agriculture, forestry, fisheries, etc. increases, the number of traders who handle the forecasts also increases, competition intensifies, and local weather forecasts with lower cost and higher accuracy are obtained. Forecasts have been required. In order to respond to this, various methods for cost reduction and accuracy improvement are being studied.

One of the methods that can be easily conceived is to fly a small balloon on which an aluminum vapor-deposited layer is formed, and record the floating path by tracking this with a radar. However, this method has proven to be more difficult to implement than expected. In the air,
Rain, clouds, fog, snow, and other floating objects, as well as unexpected noise, can disturb the screen, and the radar reflections are too small to see. The only way to do this is to ignore the cost, make the balloons larger and use high-performance radar.

Observation of the wind using such a balloon is not practical in terms of practical use. In terms of environment and cost, not only is the helium, which is a valuable resource even from a balloon, but also the balloon itself, It can be seen that it is almost impossible to reuse and regenerate because of difficulty in recovery. In the end, after a crash, they are left scattered in various places, and may eventually cause pollution problems as garbage. In general, small businesses that perform local weather forecasting operations have few employees and are unstable in management, except for those that operate as branch offices or branch offices in partnership with large weather forecasting companies. There are many things. Therefore, even if it is a small amount, if spending is repeated every day, even a company that is stable in management will be a considerable burden,
In addition, unstable companies may endanger their management. Observations for the purpose of weather forecasting are meaningless without accumulating data, so balloons must be flown on days when there is no order or on holidays. For this reason, if the number of employees is too small, it is likely that it is difficult to organize work cycles for night shifts and holiday work, and if it is avoided, labor costs will increase or increase, or it will increase. Enormous costs must be devoted to the equipment.

[0017] In addition, in the case of a rapid drop of the airflow accompanied by the drop of raindrops, that is, a so-called "down burst", a large amount of raindrops can be detected by a Doppler radar. However, it is almost impossible to observe only wind with radar without rain clouds or raindrops.

In order to save cost, the balloon may be flown without installing a radar, but it is possible to pursue the balloon as it is visually, using a binocular or a telescope, or using a bicycle or a motorcycle. . In the case of ordinary weather forecasts, the accumulation of the results of regular observations is essential, so it is necessary to repeat the number of times, but it is impossible to confirm the position by visual observation or tracking depending on the weather, time zone and terrain. The disadvantage is that it is very cumbersome, and the resulting data is difficult to organize in numerical or graphical form, making it difficult to use. Generally, it is necessary to accumulate weather observation data for at least four months, preferably one year, for local weather forecasting.

In some cases, a streamer is used as a preparation for the flight of a simple glider such as a hang glider or a paraglider, or at a training airfield, an airfield for a small aircraft, a heliport, or the like. It is little useful for weather forecasting. In addition, as a preparation for launching fireworks, it is often practiced to use a streamer or fly an inexpensive balloon and track it with the naked eye to determine the wind direction and wind speed to determine whether or not to hold the fireworks. Observations of winds by windsocks and balloons cannot be accurately recorded, and thus cannot be officially adopted in local weather forecasts.

Currently, widely used, for example,
2 is an anemometer (10) shown in FIG.
Is connected to a two-pen wind direction and wind speed recording device (20) shown in FIG. FIG. 3 shows only a small part of the recording paper (30) used in the wind direction and wind speed recording device (20). The wind speed is on the left side (31) and the wind speed is on the right side (32). The wind direction is recorded.

In weather observations, it is important to know in which direction, at what speed, and at what speed (after all, how much) the wind has moved at a certain point. But,
When the conventional apparatus and recording shown in FIGS. 1 to 3 are used, since the wind direction and the wind speed are separately recorded,
If the wind condition at that point is to be comprehensively determined, it is easy to consider that it is better to read the wind direction and wind speed individually, and then organically correlate both data.

At first glance, it is impossible for an expert to know the movement of the wind from the recording paper (30).
After individually viewing the two types of graphs, the wind speed on the left side (31) and the wind direction on the right side (32), it is necessary to organically relate the two to visually imagine the movement of the wind itself. However, even if the wind direction changes frequently, it is almost impossible because the same graph lines stick to each other.

In weather observation, the "wind direction" is the "windward direction" and the "wind blowing direction". Conventionally, “wind direction” is “wind speed” when thinking about “wind”.
Together, it is the first word that comes to mind. Actually, the influence is larger in the "wind blowing direction", that is, "leeward" than in the "wind direction". Psychologically, "wind direction" is "only the direction of the wind coming here and does not feel spread", whereas "wind spreads as it is downwind", and actually "wind direction" Has a greater impact. In a ship, it is similar to the direction of the route, that is, the course of the route, not the problem.

In order to capture the trajectory of a wind that is invisible to the naked eye, in particular, a local wind, it is a fast way to capture the movement of a virtual balloon being blown by this wind. However, in this method, as described above, in order for the small business to continue as a business, it is easy for the business to be overwhelmed.

The situation that requires local wind observation is not only when providing local or daily local weather forecasts, but also when sudden accidents that have a significant impact on the environment occur. Are born and require temporary or short-term observations. For example, a spontaneous outbreak is the occurrence of photochemical smog in the center of a large city.

In addition, accidents that are caused by unnatural spontaneous environmental pollution include leakage and diffusion of radioactive gas at nuclear material reprocessing plants in Tokai-mura, Ibaraki Prefecture, and hazardous accidents such as the Matsumoto Sarin incident. Examples include the artificial distribution and diffusion of gas. Observation of wind data in such cases often requires little accumulation of observation data due to the short-term nature (non-permanence) of the incident.

In the case of such a sudden incident, the observation device is mounted on a car or the like and rushed to the site.
If observations are started, the display or recording of the arrival area and arrival time of toxic gas deployed in real time as a bird's-eye view should be very useful for confirming safe areas and taking measures such as guidance and instructions for evacuation. is there.

[0028]

In order to improve the accuracy of the local weather forecast, weather information such as AMeDAS that is announced every day and the necessary local observations made for the weather forecast are performed. It is best to make a comprehensive judgment taking into account the results. In addition to requiring considerable equipment costs for this implementation, it must cover the cost of night and holiday work, regardless of whether or not orders are received for weather forecasts.

A first object of the present invention is to be completely unmanned when observing wind for local weather forecasting, as if a balloon for observation is emitted at a desired time, and a virtual balloon is tracked by radar. In order to provide a simulator capable of displaying or recording the floating path and the current position in real time, the conventional basic weather observation equipment such as an anemometer, In addition to local weather observations using normal weather data from anemometers, barometers, thermometers, hygrometers, rain gauges, etc., from a completely new perspective, you can understand at a glance, a bird's-eye view of the course of the wind The aim is to improve the accuracy of local weather forecasts by obtaining display and recording methods and devices.

The second object of the present invention is to generate a catastrophic accident that greatly affects the environment, for example, the occurrence of photochemical smog, the leakage and diffusion of radioactive gas, and the Matsumoto Sarin incident. In the event of an accident such as the artificial dispersion and diffusion of hazardous gas, the observation device of the present invention should be mounted on a car or the like and rushed to the site. By displaying or recording the arrival area and arrival time, and the diffusion area and the diffusion time based on the two-dimensional data that can be seen at a glance, it is easy to take measures such as instructing a safe area and guiding to evacuation.

[0031] A third object of the present invention is to provide a localization which makes it possible to precisely predict changes in wind direction and speed by superimposing or shifting simulation results of a plurality of successive simulations. It is an object to obtain a wind observation method and apparatus for weather forecast.

A fourth object of the present invention is to provide a station which can be easily purchased, maintained, maintained, handled, and easily analyzed even by a small company which conducts local weather forecasting. It is an object of the present invention to provide a wind observation method and apparatus for local weather forecast.

A fifth object of the present invention is to provide a method and an apparatus capable of creating a weather chart in which the accuracy of a local weather forecast is further improved as compared with the conventional art.

Other objects of the present invention will be apparent from the following description and the accompanying drawings.

There are several embodiments of the method and apparatus of the present invention for displaying or recording the course of the wind in real-time as a bird's-eye view at a glance. The outline of the configuration of the first embodiment is an instantaneous wind direction / wind speed detection unit (100) shown in FIG.

FIG. 5 is a view of the X-coordinate value reading device (210) in the minute vector generating device (200) of FIGS. 4 and 7 as viewed from above the cover (240). One of the output terminals of the DC generator (104) that rotates and generates electric power by the propeller type wind turbine (102) in FIG. 4 is connected to the X-coordinate value via the adjustment rheostat (202) in the circuit diagram shown in FIG.

When the wind blows, the propeller type windmill (102) shown in FIG. 4 starts to rotate, and generates a voltage substantially proportional to the wind speed within a practical range. At the same time, the body part (101) is also rotated by the vertical tail-type wind direction plate (105) so as to maintain the same angular phase as the wind, that is, constantly rotates in accordance with the wind direction. In some cases, the body (101) may
The rotation shaft (107) and the crankshaft (242) may be connected so as to rotate while maintaining an angle difference of 0 °.

Now, it is assumed that the balloon of the virtual floating body is discharged into the air. For reference, the installation location of the observation device is determined by the World Meteorological Organization (WMO = World Meteorological) in order to obtain a wind value with good representativeness.
al Organization) recommends a height of 10 meters above the ground, but other heights are possible depending on the terrain.

Then, what kind of observation is required for local weather observation and local weather forecasting? Simply put, it can levitate along the surface or sea level,
Assuming that an object such as a light balloon was released from the hand at a certain time and at a certain point and left as it was blowing the wind, where the balloon arrived minutes or hours later Is shown continuously. If this is possible, consider replacing this balloon with fine particles, powder or fog, such as dioxins, pesticides, or radioactive materials.
It is possible to presume that it has reached the vicinity of the area corresponding to the terminal end of the drawing line displayed or recorded on the floating path display recording device (300) in real time, and that the area around the drawing line is substantially contaminated.

30) is applied to the input terminal.

FIGS. 5 and 7 show an X-coordinate reading device (X-axis potentiometer) (210) shown in FIG. 8 and a Y-coordinate reading device (Y-axis potentiometer) (23) shown in FIG.
0) and the housings (214) and (234), respectively.
The upper and lower layers are incorporated into the inside, and further, the cover (240) (FIG. 5) placed thereon is shown as being integrally assembled. At the center of the upper surface of the cover (240), a bearing (241) is provided so as to protrude. The bearing (241) is provided on the cover (240) so that a crankshaft (242) for moving two brushes (213) (233) can rotate. It is inserted almost vertically. The upper end of the crankshaft (242) is connected to the rotating shaft (107) of the airframe fuselage anemometer (100).

The feature of this embodiment is that the two housings (214) and (234) have the same shape and the same size for mass production, and the assembly is fixed at a position rotated by 90 degrees with respect to each other. This is the point to be performed.

FIG. 8 is a plan view showing the inside of the housing (214) of the X-axis potentiometer (210), which is the X-coordinate reading device (210), with the cover (240) of FIG. 5 removed. In the center is an airplane fuselage anemometer (10
0), there is a crankshaft (242) connected to the rotating shaft (107), and the lower end thereof has a crank arm (24).
3) is fixed. The aforementioned crank arm (24
A crank pin (244) is fixed to the lower surface of the free end of 3). In the housing (214), for example,
A pair of guide rails (215) and (216) made of a round bar and corresponding to the X coordinate axis are fixed.
A sliding member (217) is fitted into the pair of guide rails (215) and (216). Sliding member (217)
The guide rails (215) and (216) are formed with long holes (218) in a direction perpendicular to the guide rails (216). The crank pins (244) penetrate through the crossheads (219) almost without rattling. This causes the crankshaft (242) to be connected to the airplane fuselage-type anemometer (100).
When the sliding member (217) rotates in conjunction with the rotating shaft (107), the sliding member (217) slides in the X-axis direction along the guide rails (215) and (216). Therefore, the sliding member (21)
7) The brush (213) mounted on the resistor (21)
1) Lightly slide on the top.

The crank pin (244) has a large round hole (22) formed in the bottom of the housing (214).
After passing through 0), it has reached the lower housing (234). As shown in FIG. 9, the lower housing (234) has substantially the same structure as the upper housing (214) of FIG. 8 rotated 90 degrees counterclockwise.

The lower half of the crank pin (244) penetrates through the elongated hole (238) of the lower sliding member (237) via the crosshead (239) with almost no play. When the crankshaft (242) rotates with the rotation axis (107) of the aircraft fuselage-type anemometer (100), the sliding member (237) is moved by the guide rail (23).
5) Sliding in the Y-axis direction along (236). Therefore, the brush (23) mounted on the sliding member (237)
3) slides lightly on the resistor (231).

According to such a structure, the direction in which the vertical tail-type wind direction plate (105) is directed (there are two cases, the windward direction and the leeward direction) is displayed by the rectangular coordinate values.

In order to capture the instantaneous wind speed and the instantaneous wind direction as minute vectors and to continuously integrate the minute vectors, the DC voltage Vx output from the X-coordinate value reader (210) (X-axis related potentiometer) is floating. Route display recording device (30

DC voltage Vy which is the output of the shaft-related potentiometer)
Is applied to the reversible DC motor (330) (see FIGS. 6 and 7) of the Y-axis carriage (340) of the floating path display and recording device (300) (XY plotter).

A Y-axis carriage (340) is mounted on the X-axis carriage (320), and the Y-axis carriage (340) is moved by the reversible DC motor for X-direction movement (310). Move in the X-axis direction.

Further, on the Y-axis carriage (340), a recording pen unit (400) that moves in the Y-axis direction by the above-mentioned reversible DC motor for moving in the Y direction (330) is mounted. Constitutes a recording head (402) in which various kinds of color pens (401) can be freely replaced by a command. This point is known by the structure of the conventional XY plotter.

Next, the operation of this embodiment will be described. First, in FIGS. 4, 5 and 6, when the wind blows, the propeller-type windmill (1) of the airplane fuselage-type anemometer (100) is used.
02) rotates to drive the DC generator (104). Therefore, electric power proportional to the wind power is supplied to the two potentiometers (210) and (230). Thus, the voltage (Vx) (Vx) () applied to each of the reversible rotary DC motors (310) and (330) of the rectangular coordinate recorder (XY plotter) (300) via the potentiometers (210) and (230). Vy) depends not only on the rotation speed of the anemometer, but also on the position of each brush (213) (233) with respect to each resistor (211) (231) (in the first place, the direction of the vertical tail-type wind vane (105)). fluctuate.

Thus, the recording pen (401)
As long as there is wind, it moves in the direction of the vertical tail-type wind direction plate (105) (it may be set to be opposite) at a speed proportional to the wind speed.

FIG. 10 shows the instantaneous wind direction and the instantaneous wind speed of the wind passing through one point recorded by the apparatus of the present invention as a minute vector, and the minute vector is integrated with respect to the elapsed time. (500).

On the recording paper (500), one meridian (510) and one latitude line (520) are printed, and the intersection (550) is the starting point of the recording pen (401). That is, it is the origin of the rectangular coordinates. Therefore, at the start of recording, it is necessary to align the tip of the recording pen (401) with the origin (550). (5
Reference numeral 60) denotes a line drawn by the recording pen (401). On the line (560), a point (561) of a different color is applied every time a predetermined time elapses after activation, or at a certain time or You can know the wind situation within a certain time. For example, now at 6:00 am the origin (550)
The position of the recording pen (401) started one hour after, the position two hours later, the position three hours, the position four hours later, the position five hours later, and the position six hours later, Assuming that the position after 7 hours is the position after 8 hours, the wind direction at 11:00 am is indicated by a broken line (57
0). The average wind direction from 7:00 am to 9:00 am matches the direction of a straight line connecting the dabs.

The recording method in the apparatus according to the present invention includes the following 2
There is a street. That is, the first method is to make the recording pen (401) move in the direction that the vertical tail-type wind vane (105) points. The curve of the integral value drawn by this method is suitable for knowing from which direction and how much wind blew and how long. To carry out this method, a vertical tail type wind vane (105)
Is aligned with the direction of the free end of the crank arm (243).

The second method is a vertical tail-type wind direction plate (10
The recording pen (401) moves in the direction opposite to the direction of 5). At a glance, the curve of the integrated value drawn by this means that it can be seen that it roughly shows the trajectory of a balloon released in the air flying on the wind. Therefore, it is effective for local or small-scale weather observations and forecasts. In order to perform this method, the direction in which the vertical tail-type wind direction plate (105) is directed may be completely opposite to the direction of the free end of the crank arm (243). That is, they are 180 degrees apart from each other.

As a result, only a very simple difference exists between these two types of recording methods. In short, if the recording paper by both methods is turned by 180 degrees in a plane, it will match the recording by the other method.

Even if the time interval of measurement is isochronous, recording of the time is very significant if the movement or phenomenon of the object to be measured is unequal. Especially in the case of wind, the wind speed varies from no wind to several tens of meters per second, and the wind direction also changes rapidly.

For this reason, in the observation recording apparatus of the present invention, it is also possible to record by not drawing continuous lines but by drawing points every predetermined time. This has been conventionally used in self-recording anemometers.

During recording, the time can be indicated by drawing a different color on the drawing line every predetermined time.

However, during recording, there is no wind or the wind direction changes drastically, and the drawing line or drawing point may intersect. Therefore, it is not possible to read the relationship among the three directions of wind direction, wind speed and time. It is possible. As a method for preventing this, the color of the recording ink is changed every time a predetermined time elapses. In this method, a plurality of pens having different colors of ink are prepared, and a necessary pen is selected from the pens by a signal. However, this method has already been put to practical use for a multicolor plotter.

As the recording paper, it is preferable that the base line of the rectangular coordinates is printed, but it is more preferable that the name of the azimuth is printed. It is desirable to use continuous paper with perforations on both the left and right edges in order to perform automatic feeding such as charging and discharging to a recording position, such as a computer printer.

The best recording paper is a map of the area including the location where this device is installed. After placing the origin of the rectangular coordinate axis at the installation location on the map, the azimuth may be checked.

If the windless or weak wind continues for a long time, the drawing line (560) starting from the origin (550) of the rectangular coordinates of the recording paper (500) may be changed to the origin (550) in some cases. ) May be recorded in a lump in the vicinity. In such a state, the record cannot be read sufficiently.

If the strong wind condition continues for a long period of time, particularly in a certain direction, the drawing line (560) may protrude from the recording paper (500).

As a countermeasure against these, a DC generator (10
4) From each potentiometer (210) (230)

In the wind observation recording apparatus according to the present invention, in one embodiment, the color of the drawn line is changed every predetermined time, so that even if the drawn line intersects due to a large change in the wind direction or the wind speed, the confusion occurs. And easy to read.

In one embodiment of the wind observation and recording apparatus according to the present invention, the recorded paper automatically deviates from the recording position and the recording pen automatically moves to the origin after a predetermined period of time has elapsed since the start. The observation is continued without any human error or interruption.

The use of the map in which the wind direction and the wind speed are integrally recorded by the observation recording apparatus according to the present invention is very large so that it can be read at a glance.
