Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fog elimination system for observing the distribution of fog generated in a moving body passage and its peripheral portion, and efficiently eliminating the fog near the moving body passage.

[0002]

2. Description of the Related Art In general, fog generated on a moving body passage such as an expressway, a bay road or an airport significantly deteriorates the visibility of a driver of a moving body (for example, an automobile) traveling on the moving body passage. This has caused an increase in the incidence of traffic accidents on mobile passages. On the other hand, measures such as speed regulation and traffic regulation are taken to prevent such accidents from occurring, but such means reduce the logistics function, and There were problems such as the loss of the original function.

On the other hand, researches have been made on a system for ensuring the safe running of an automobile or the like by positively eliminating the fog generated on such a moving body passage. For example, Japanese Patent Application Laid-Open No. 7-317039 has been studied. Japanese Patent Application Publication No. JP-A-Heisei 8-100419 has proposed a fogging apparatus for roads for automobiles and a fogging apparatus described in Japanese Patent Application Laid-Open No. H8-100149.

[0004]

However, what is called a conventional so-called fogging apparatus or fogging system is disclosed in, for example, JP-A-7-317039 or JP-A-8-10.
Detection means (light receiver 9, fog sensor 4) provided on the moving body passage, such as a fogging apparatus described in Japanese Patent No. 0419, detects the presence or absence of fog generated on the moving body passage, and detects this. The system is configured to eliminate fog based on the result, and there is no particular monitoring for the presence or absence of fog generated in the periphery of the moving body passage.

[0005] Further, the above-mentioned fog which causes a traffic obstruction does not usually occur only on the moving body passage, but also occurs in the peripheral portion thereof and flows into the moving body passage. As a result, the driver's view of the vehicle passing through the moving body passage is deteriorated for a long time.

In such a situation, when the mist elimination device including the heating means is operated based only on the presence or absence of the mist in the passage of the moving body, the mist elimination device has a mist that far exceeds its own mist elimination ability. Can be operated irrespective of whether or not it is generated near the moving body passage, so that, for example, despite the fact that its own demisting effect is significantly reduced, it can be operated for a long time in such a state In other words, there is a problem that the fog elimination effect is extremely poor and wasteful demisting energy is consumed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the fog elimination means provided in the moving body passage is optimally adjusted according to the distribution of fog generated in the moving body passage and its peripheral portion. It is an object of the present invention to obtain a new fog elimination system that can be operated and that can perform efficient and efficient fog elimination while suppressing the consumption of wasteful demisting energy.

This is fog elimination means.

The fog distribution detection processing means 2 of the fog elimination system according to the present embodiment, specifically, performs fog distribution detection processing based on the observation result of the fog observation means 1 as shown in FIG. It comprises a detecting means 5 and a fog distribution movement estimating means for performing a movement estimating process for the detected fog distribution based on the detection result of the fog distribution detecting means 5.

Reference numeral 9 denotes a moving body such as an automobile moving on the moving body passage, 9 denotes fog generated in a peripheral portion of the moving body passage, and 10 denotes an observation range of the fog observation means 1 visually shown. As shown in FIG. 2, the observation range 10 of the fog of the fog observation means 1 is wide, and it is possible to observe not only the vicinity of the moving body passage but also a target (fog, rainfall, etc.) generated in the periphery thereof. . Further, since the fog elimination range of the fog elimination means 4 is limited in terms of its ability, as shown in FIG. A plurality of fog elimination means are arranged at predetermined intervals according to the fog elimination ability and the like. The details of controlling the plurality of fog elimination units based on the observation result of the mist observation unit will be described in detail in another embodiment.

Next, the operation will be described in detail. FIG. 3 is an operation flowchart showing a series of processing operations of the fog elimination system shown in FIG. In the fog elimination system according to the present embodiment, first, fog is observed by the fog observing means 1 in the moving object passage and its peripheral portion (S01). As described above, the fog observation step S01 is performed by a weather radar device or the like capable of observing generation of fog over a wide range. The observation result of the fog observation means 1, that is, observation data is input to the fog distribution detection means 5. . And fog detecting means 5
Then, the fog distribution is detected for the fog generated in the moving object passage and its peripheral portion based on the input observation data (S02).

In general, the operating frequency of a weather radar device is
According to a meteorological radar device using S band, C band or X band, but using a transmission frequency higher than the X band, for example, a frequency called a millimeter wave, observation of fog particles smaller in size than raindrops is performed. By using a weather radar device in the millimeter wave band as fog observation means, the fog distribution detection means 5 allows the two-dimensional or three-dimensional fog generated in the moving body passage 1 and its surroundings. Fog distribution can be detected. According to the weather radar device, it is also possible to detect the density distribution and the like of the fog distribution observed by the strength of the reflected radio wave.

When the fog distribution is detected in the fog distribution detecting step S02 of the fog distribution detecting means 5, the detection result, that is, observation data on the fog distribution is inputted to the fog distribution predicting means 6, and the fog distribution predicting means is provided. A movement prediction process is performed on the fog distribution detected in S6 (S03). Observation data on the fog distribution detected by the fog detection means 5 is input in time series to the fog distribution prediction means 6, and the fog distribution prediction means 6 is based on the observation data of the fog distribution in this time series. The position of the fog distribution after a predetermined time elapses, the distribution status, and the like are predicted. The fog observation step S01 by the fog observation means 1 is repeatedly performed, for example, at predetermined time intervals. Observation data on a time-series fog distribution is obtained by the fog observation performed by the fog observation means 1 repeatedly. can get.

Referring to FIG. 2, the fog distribution estimating means 6 determines the fog 9 based on the observation data on the fog distribution inputted in time series from the fog detecting means 5 and moves the fog 9 to the moving body passage 7.
Is predicted to be approaching the vicinity of the fog eliminating means 4b,
Based on the moving speed, the moving direction, and the like, a prediction process is performed on a specific route, arrival time, and the like until the fog 9 reaches the moving body passage 7. Then, the arrival time, arrival position, and the like of the fog 9 in the moving body passage 7 are calculated from the result of the fog distribution prediction processing step 03 of the fog distribution movement prediction means 6.
The fog distribution prediction means 6 outputs the prediction processing result to the control means 3 as the processing result of the fog distribution detection processing means 2, and the control means 3 outputs the processing result of the fog distribution detection processing means 2, that is, the fog distribution movement prediction means 6. The fog removing operation of the fog removing means 4 is controlled based on the result of the prediction processing (S04).

Therefore, according to the fog elimination system according to the present embodiment, the fog distribution of the fog generated in the peripheral portion of the moving body passage 7 can be detected, and the detected fog distribution is located at any position of the moving body passage 7. It is possible to predict in advance when the vehicle will arrive, and the control unit 3 controls the erasing operation of the mist elimination units 4a to 4c arranged in the moving body passage 7 according to the processing result of the mist distribution detection processing unit 2. be able to.
For example, in the situation as shown in FIG. 2, it is possible to predict in advance that the influence of the fog 9 generated in the peripheral portion of the moving body passage 7 on the moving body passage 7 is in the vicinity of the fog elimination means 4b,
The control unit 3 controls the erasing operation of the mist elimination unit 4b based on the detected distribution content of the fog distribution and the movement prediction result. Further, since the arrival time of the mist 9 in the moving body passage 7 can be predicted in advance, the control means 3 can start the erasing operation of the mist erasing means 4b before the mist 9 reaches the moving body passage 7, The fog 9 arriving at the moving body passage 7 can be more effectively eliminated.

Further, since the density distribution of the fog 9 can also be grasped by the fog detecting means 5, it is possible to control the erasing operation of the fog erasing means 4b according to the fog distribution of the fog 9 arriving at the moving body passage. . For example, in a situation where the fog 9 is staying in the vicinity of the mobile passage 7, if the hindrance to the traffic of the fog 9 is small (the density of the fog is relatively low), the low output of the fog eliminating means 4 b is used. Fog erasing means 4b
Foggy energy can be suppressed, and wasteful foggy energy consumption can be prevented.

FIG. 2 shows a situation in which the mist 9 is generated at a position far away from the moving body passage 1. However, the same applies when the mist 9 is generated in the vicinity of the moving body passage 7. Reference numeral 3 controls the erasing operation of each of the mist elimination units 4a to 4c based on the detection processing result of the mist distribution detection processing unit 2.

As described above, according to the fog elimination system according to the present embodiment, the generation of fog is observed over a wide area including the moving body passage 7 and its peripheral portion, and the fog distribution is detected for the observed fog. Performs the movement prediction, the erasing operation of the fog erasing means 4 arranged in the moving body passage 7 can be controlled according to the so-called fog environment around the moving body passage, and the wasteful erasing operation of the fog erasing means is prevented. As a result, the fog erasing operation using the fogging energy can be performed more efficiently.

Embodiments 2 Next, another embodiment of the present invention will be described with reference to FIGS. The fog elimination system according to the above-described embodiment performs fog distribution detection processing for fog observed from the observation data obtained by the fog observation means 1, further performs movement prediction processing, and performs control processing based on the processing results. Controls the erasing operation of the fog erasing means 4. However, the fog erasing system according to the present embodiment takes into consideration not only the processing result of the fog detection processing means 2 but also the effect of fog erasing by the fog erasing means 4. Then, the continuation or stop of the erasing operation of the fog erasing means 4 is controlled.

FIG. 4 is a block diagram showing a block diagram of the fog elimination system according to the present embodiment. In FIG. 4, reference numeral 11 denotes, for example, disposed near the fog elimination means 4 or at a predetermined position in a moving body passage. The fog detecting means 12 for detecting the presence or absence of fog near the body passage receives the detection result of the fog detecting means 11 and receives the effect of fog elimination by the fog elimination means 4 (hereinafter referred to as fog elimination effect).
It is called the defoaming effect. Defoaming effect determining means for determining
Is input with the processing result of the fog distribution detection processing means 2 and the determination result of the mist removal effect determination means 12, and is based on the processing result of the mist distribution detection processing means 2 and the determination result of the mist removal effect determination means 12. This is control means for controlling the erasing start operation or the continuation / stop operation of the fog erasing means 4. In the drawings, the same reference numerals denote the same or corresponding parts, and a detailed description thereof will be omitted.

Next, the operation will be described. FIG. 5 is an operation flowchart showing a series of processing operations of the fog elimination system according to the present embodiment shown in FIG. 4. In the fog elimination system according to the present embodiment, the processing steps S01 to S04 shown in FIG. Further, each of the processing steps S05 to S07 shown in FIG. 5, that is, a processing step of detecting the presence or absence of fog near the moving body passage by the fog detecting means 11 after the fogging operation by the fog removing means 4, and a detection result of the fog detecting means 11 And a processing step in which the fogging effect determining means 12 determines the fogging effect by the fog removing means 4. In addition,
The processing steps S01 to S04 are the same as those of the fog elimination system according to the above embodiment, and the description thereof will be omitted.

When the fog erasing means 4 performs a complete erasing operation based on the processing result of the fog distribution detecting means 2, the fog detecting means 11 is installed to check the fogging effect. The presence or absence of fog near the moving body passage detected is detected (S05). The fog detection in the fog detection step S05 is performed, for example, by referring to FIG.
May be configured by the combination of the light receiver 9 and the detection circuit 10 as shown in FIG. The detection of the fog may be performed a plurality of times, and the average value may be used as the detection result. The number of detections is set according to the detection accuracy.

The detection result of the fog detecting means 11 is inputted to the fogging effect determining means 12, and the fogging effect determining means 12 determines the fogging effect of the fog removing means 4 based on the detection result of the fog detecting means 11. (S06). For example, if the presence of fog is confirmed from the detection result of the fog detecting means 11, the fogging effect determining means 12 determines that the fogging effect by the fog erasing means 4 is not so large. Then, the determination result of the demisting effect determination unit 12 is output to the control unit 13, and the control unit 13
Processing result of fog distribution detection processing means 2 and fogging effect determination means 1
The erasing operation of the fog erasing means 4 is continuously controlled on the basis of the result of the determination in Step 2. The details are as follows.

Next, the control operation of the control means 13 based on the result of the judgment made by the demisting effect judgment means 12 and the result of the processing by the fog distribution detection processing means 2 will be described in detail with reference to FIG. FIG. 6 is an operation flowchart showing the processing operation of the control means 13 based on the determination result of the fog effect determination means 12 and the processing result of the fog distribution detection processing means 2 described above. Based on the judgment result input from the judging means 12, the state of fog in the vicinity of the moving body passage (hereinafter, referred to as an effective mist removal area), specifically, the presence or absence of fog is determined (S08). When the presence or absence of fog is determined in the effective area determination step S08, the control unit 13 does not erase the fog in the demisting effective area despite the execution of the erasing operation by the fog erasing means 4. Then, in order to stop the useless erasing operation of the fog erasing unit 4 thereafter, the mist erasing unit 4 currently performing the erasing operation is instructed to stop the erasing operation (S07).

If it is determined in the effective area determination step S08 that fog is not present (absent) in the fog effective area,
The control means 13 determines that the erasing operation by the fog erasing means 4 is effective for the time being and proceeds to the next processing step. Specifically, it is determined whether or not there is a fog distribution in a peripheral portion near the moving body passage (hereinafter, referred to as a region outside the fogging effective region) (S09). This out-of-effective-area determining step S09 is for determining the presence or absence of fog distribution outside the effective area of the mist removal effect after the erasing operation by the mist removing means 4 based on the processing result from the fog distribution detection processing means 2. After the erasing operation by the erasing unit 4, when the mist distribution detection processing unit 2 detects the mist distribution outside the mist elimination effective area, the mist elimination effect determining unit 12 determines that the erasing operation by the mist erasing unit 4 is effective. In order to continue the erasing operation of the mist erasing unit 4, the mist erasing unit 4 currently in operation is instructed to continue the erasing operation (S10).

If it is determined in step S09 outside the effective area that no fog distribution is present outside the effective area for fogging, the control means 13 removes the fog near the moving body passage by the fogging operation by the fog removing means 4. Judge as almost deleted,
Also, in order to stop the useless erasing operation of the fog erasing unit 4, the mist erasing unit 4 currently in operation is instructed to stop the erasing operation (S07). FIG. 7 is an explanatory diagram showing the relationship between the fog-effective area and the outside of the fog-effective area. The fog-effective area 14 is an area near the moving body passage where fog detection means 11 can detect the presence or absence of fog. The area 14 outside the demisting effective area is a very peripheral area near the moving body passage where the fog detection means 11 cannot detect the presence or absence of fog, but the fog distribution is detected by the observation of the fog observation means 1. (Refers to a range narrower than the periphery of the moving body passage which is the observation range of the fog observation means 1).

As described above, according to the fog elimination system according to the present embodiment, the fog elimination system according to the above embodiment is further provided with fog detection means 11 for detecting fog near the moving body passage and fog detection means 11. A fogging effect determining means 12 for determining the presence or absence of fog near the moving passage based on the detection result;
Since the fog erasing means 4 is controlled based on the result of the erasing operation, for example, in a case where the mist in the foggy-effect effective area cannot be erased even though the fog erasing means 4 is operating. The useless erasing operation of the fog erasing means 4 can be stopped, and when the fog erasing means 4 is operating effectively, the erasing operation by the fog erasing means 4 is continued so that the moving body passage is removed. Fog, which has a great effect on the traffic of the city, can be effectively and efficiently eliminated.

Embodiments 3. Next, another embodiment of the present invention will be described with reference to FIGS. Embodiment above. As shown in FIG. 7, the fog elimination system 4 determines the presence or absence of fog in the fogging effect effective area near the moving body passage 1 and the fog distribution outside the fogging effect effective area. The mist elimination operation of the fog elimination means 4 is controlled based on the mist elimination effect of the mist elimination means 4 according to the first embodiment. The erasing operation of the fog erasing means 4 is controlled according to the prediction result. The overall block configuration of the fog elimination system according to the present embodiment is basically the same as that of the above embodiment. 2 and only a partial block diagram of a characteristic portion is shown.

FIG. 8 is a partial block diagram showing the mist elimination effect determination processing means 12c of the mist elimination system according to the present embodiment. In FIG. The determination result of the effect and the corresponding determination condition (including, for example, the processing result of the fog distribution determination detection circuit 2) are stored, and the fogging effect of performing the fogging effect prediction processing based on the stored content is stored. It is a prediction unit. In the fog elimination system according to the present embodiment, when the fog distribution is detected by the fog distribution detection processing means 2, the processing result is output to the demisting effect determination means 12 and input to the demisting effect prediction means 16. A prediction process of the fogging effect based on the processed result is performed. Specifically, a corresponding determination condition stored in the fogging effect prediction means 16 is extracted using the processing result of the fog distribution detection processing means 2 as a search key, and control is performed based on a past determination result corresponding to the extracted determination condition. The validity of the contents of the erasing operation specified by the means 3 is predicted.

Next, the operation will be described. FIG. 9 is an operation flowchart showing a series of processing operations of the fog elimination system according to the present embodiment. As shown in FIG. 9, in the mist elimination system according to the present embodiment, the erasing operation by the mist elimination means 4 starts. Before the operation, the processing steps S11 and S12 for estimating the fogging effect of the fogging operation by the fog evacuation means 4 are executed, and the erasing operation of the fog erasing means 4 is started and stopped based on the result of the prediction processing. The other processing steps S01 to S10 and the like are the same as those in the above embodiment. 2 and the detailed description thereof is omitted.
According to the fog elimination system according to the present embodiment, when it is predicted that the fog elimination operation by the fog elimination means 4 is not effective in the processing step S12, the instruction to stop the elimination operation of the fog elimination means 4 is issued by the control means. By performing the step 3, useless erasing operation of the fog erasing means 4 is prevented in advance.

As described above, according to the fog erasing system according to the present embodiment, the validity of the fog erasing operation of the fog erasing means 4 is determined before the erasing operation of the fog erasing means 4 is started.
Since the control means 3 controls the erasure control of the fog elimination means 4 based on the determination result, the mist elimination means predicted without performing the erasure operation of the fog elimination means 4 as in the fog elimination system according to the above embodiment. The control means 3 can instruct the start or stop of the erasing operation of the fog erasing means 4 on the basis of the validity of the erasing operation of 4, and furthermore, it is possible to prevent useless fog erasing operation in advance.

Embodiments 4 Next, FIGS. 10 and 11 show another embodiment of the present invention.
This will be described with reference to FIG. The fog elimination system according to the present embodiment controls a plurality of mist elimination units arranged on the moving body passage based on the mist distribution detected by the observation of the mist observation unit 1. Each of the fog elimination means is disposed at a predetermined interval on the moving body passage 7 as shown in FIG. 2, for example. FIG. 10 shows a fog elimination system according to the present embodiment. The control means 17 controls the erasing operation of the plurality of fog elimination means 4 a to 4 c based on the detection processing result of the fog distribution detection processing means 2. For example, taking the operation situation as shown in FIG. 2 as an example, the fog 9 first approaches the moving body passage where the fog eliminating means 4b is arranged, and then moves on the moving body passage 1 toward the fog eliminating means 4a. If you move toward
The control means 17 controls each of the fog elimination means 4a to 4c as shown in FIG.

FIG. 11 is an erase operation time chart showing an example of the erase operation of each of the fog erase means 4a to 4c shown in FIG. 10, and FIG. 11 (a) is an erase operation time chart corresponding to the fog erase means 4a. FIG. 11B shows the fog erasing means 4b.
FIG. 11C shows an erasing operation time chart corresponding to the fog erasing means 4c. Each of the fog eliminating means 4a to 4c is
The erase operation is performed during the ON period shown in FIG. 11 designated by 7, and the erase operation is stopped in other periods. FIG.
In FIG. 1, reference numeral 18 denotes an ON period indicating an erasing operation period of each fog erasing unit. According to FIG.
Starts the erasing operation, and then the fog erasing means 4a starts the erasing operation.

The mist erasing means 4b has stopped the erasing operation a short while after the mist erasing means 4a has started the erasing operation.
b indicates that the fog has been moved from the vicinity of the fog 9 to the direction in which the fog elimination means 4a is disposed, and the control means 17 recognizes the movement of the fog 9 based on the processing result from the fog detection processing means 2; As described in 2 and 3, it indicates that the erasing operation of the fog erasing unit 4b is stopped based on the determination of the mist elimination effect by the mist elimination unit 4b by the mist elimination effect determining unit 12.

As described above, according to the fog elimination system according to the present embodiment, the control means 17 controls the plurality of fog elimination means 4.
Since the erasing operations a to 4c are controlled based on the detection processing result of the mist distribution detecting processing unit and further based on the processing result of the mist elimination effect determination processing unit, the mist erasing unit that does not need the erasing operation performs the erasing operation. Without erasing, only the fog erasing means that needs to perform the erasing operation can be efficiently operated,
Even in the case where a plurality of fog erasing units are controlled, it is possible to prevent unnecessary fog erasing operations of the respective fog erasing units.

Embodiments 5. Next, another embodiment of the present invention will be described with reference to FIG. The fog elimination system according to the present embodiment identifies a fog type, that is, a type of fog distribution (hereinafter, referred to as a fog type) with respect to the fog distribution observed and detected by the fog observing means 1, and assigns the identified fog type to the fog distribution. In response, the control means 19 selects the erasing method of the fog erasing means 4.
Specifically, an appropriate erasing method (heating means, watering means, compressed air jetting means, or a combination thereof) etc. is prepared in advance according to the fog type, and the fog type is identified from the detected fog distribution. Then, the control unit 19 instructs the above-mentioned erasing method suitable for the identified fog type to cause the fog erasing unit 4 to perform the fog erasing operation by the erasing method. The fog erasing means 4 is provided in advance with each erasing method according to the identified fog type so that the fog erasing operation according to the instruction of the control means 19 can be performed.

FIG. 12 is a block diagram showing a block diagram of the fog elimination system according to the present embodiment. Reference numeral 19 denotes control means of the mist elimination system according to the embodiment. Distribution shape, time change,
Further, fog type identification means for identifying the fog type of the fog distribution from so-called fog environments such as weather conditions such as temperature, humidity, wind direction and wind speed at the time of fog distribution occurrence;
This is an erasing method selecting means for selecting the erasing method of the fog erasing means 4 according to each fog type identified by. The erasing method selected by the erasing method selecting means 21 may be selected so as to use not only one type but also a plurality of erasing methods. The most appropriate erasing method combination is selected in consideration of the combination of a plurality of erasing methods. .

As described above, according to the fog elimination system according to the present embodiment, the mist elimination method of the mist elimination means is selected according to the mist type of the mist observed by the mist observation means 1. The fog elimination operation according to the fog type of the fog generated near the moving body passage 7 as shown in FIG. In addition to the effects described in 1, the fog erasing operation can be performed more effectively.

Embodiments 6. Next, another embodiment of the present invention will be described with reference to FIG. In the above embodiment, the case where each of the fog observation means 1 is a weather radar device has been described. However, this fog observation means 1 can detect fog distribution or predict movement of the fog distribution in the fog distribution detection processing means 2. If it is,
Hereinafter, a case where another fog observation device is used as fog observation means will be described. FIG. 13 is a system conceptual diagram schematically showing an application state in which the fog elimination system according to the present embodiment is applied to a moving object passage, for example, a highway, etc. As shown in FIG. In the system, the fog observation means is constituted by a number of visibility meters arranged around the moving body passage.
