It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The position selecting method of the fog monitoring equipment can be applied to the application environment shown in fig. 1. Wherein a user terminal 102 communicates with a server 104 over a network. The server 104 acquires the fogging data and extracts wind field data from the fogging data; calculating an average wind direction according to the wind field data; determining the area to be surveyed by taking the area to be monitored as a center and taking a preset radius and a preset angle as parameters, wherein the wind direction angle corresponding to the average wind direction is within an angle range limited by the area to be surveyed; the installation position of the fog monitoring device is extracted from the area to be surveyed. Further, the acquired installation position may also be pushed to the user terminal 102 to instruct the user to install the fog monitoring device at the preset position.
The user terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a location selection method for a fog monitoring device is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and in other embodiments, the method can also be applied to a terminal, and the method includes the following steps:
and step 210, acquiring the fogging data, and extracting wind field data from the fogging data.
Specifically, the server may obtain meteorological data of a certain area within a preset time, for example, the server may obtain meteorological data of a target area for at least ten years from a meteorological bureau, where the meteorological data includes weather conditions (e.g., whether fog exists) every day, wind direction data every day, and the like. Then the server picks out the data corresponding to the foggy weather from the meteorological data to obtain the foggy data, and then the data of the foggy weather are analyzed, and specifically, the server can extract the wind field data in the foggy weather. The wind field data may include a wind direction, a wind size, a wind influence range, and the like.
And step 220, calculating an average wind direction according to the wind field data.

For example, the average wind direction may be obtained by calculating an average value of each wind direction data, or an average wind direction may be obtained by calculating a median or a mode of each wind direction data, which is not limited herein.
The wind direction refers to an angle corresponding to the main wind, for example, the range may be 0-360 degrees, where 0 degree or 360 degrees represents a north wind, that is, the wind blows from the north direction, and 90 degrees represents an east wind. Under the action of wind, the fog can be diffused to an area to be monitored, so that the determination of the average wind direction has important significance for determining the source direction of the fog.
It should be noted that, when calculating the average wind direction, only wind field data corresponding to the fog weather during the time period of fog occurrence and fog duration is calculated, and wind field data during the time period of no fog occurrence is not considered.
And step 230, determining the area to be surveyed by taking the area to be monitored as a center and taking a preset radius and a preset angle as parameters, wherein the wind direction angle corresponding to the average wind direction is within an angle range limited by the area to be surveyed.
The area to be monitored is an area which needs to be subjected to fog monitoring, and is generally a residential living area. The preset radius is a safe radius, and means that when the fog occurs, the fog is not or hardly influenced by the fog within a preset time in an area limited by the preset radius.
As shown in fig. 3, a schematic illustration of an area to be surveyed is provided. Specifically, the server may determine an arc using the area to be monitored as a center of a circle, using a preset radius and a preset angle as parameters, and determine the area to be surveyed according to the arc. As shown in FIG. 3, the angle corresponding to a circumferential range is [2k π,2k π +360 ° ], k ≧ 0, and is an integer. And determining an arc by taking the preset radius R as a radius and a preset angle of 90 degrees as parameters, wherein the area determined by the arc is the area to be surveyed, and the wind direction angle corresponding to the average wind direction is in an angle range defined by the area to be surveyed, that is, when the circle center angle interval corresponding to the area to be surveyed is [285 degrees, 375 degrees ], the wind direction angle corresponding to the average wind direction is also in an interval range corresponding to [285 degrees, 375 degrees ], and the angle can be 330 degrees. In other embodiments, the predetermined angle is not limited in size.
In other embodiments, the process of determining the area to be surveyed may also be determined in a manner other than by a circular arc, such as determining a rectangular area by determining a preset radius, determining the area to be surveyed according to the rectangular area, and the like, which are not limited herein.
The area to be surveyed, determined from the circular arc, is the area to be examined further, in which the best installation position can be selected.
The installation location of the fog monitoring device is extracted from the area to be surveyed, step 240.
Specifically, the server may survey the terrain of the area to be surveyed, such as extracting and marking the locations of valleys, rivers, lakes, or elevations in the area to be surveyed on a map, or may also mark the locations of peaks around the valleys, the locations of elevations near rivers and lakes, and the like.
The server can acquire a corresponding satellite map according to longitude and latitude information corresponding to an area to be surveyed, extract corresponding satellite base data in the satellite map, wherein the satellite base data can store data information of valleys, rivers and lakes, further acquire place position information of the valleys, the rivers and the lakes according to the base data, search high place position information within a preset position information range, and send the searched high place position information to a user so as to indicate the user to investigate the place on the spot.
In this embodiment, the area to be surveyed can be determined by acquiring the fogging data corresponding to the area to be monitored and calculating the average wind direction according to the average wind direction, the preset radius and the preset angle as parameters, and then the installation position of the fog monitoring device can be determined in the area to be surveyed.
In one embodiment, a flow diagram for determining an area to be surveyed is provided, as in FIG. 4. The area to be surveyed is determined by taking the area to be monitored as the center and taking the preset radius and the preset angle as parameters, and the wind direction angle corresponding to the average wind direction is in the angle range limited by the area to be surveyed, and the method comprises the following steps of:
and step 410, adjusting the wind direction angle according to a preset angle to obtain a monitorable angle interval of the fog monitoring equipment.
If the size of the wind direction angle is adjusted according to the preset angle, the wind direction angle is added with or subtracted from the preset angle. If the wind direction angle that average wind direction corresponds is A degree, predetermines the angle and is B degree, then adjust wind direction angle A according to predetermineeing the rule and can be: and on the basis of A, adding or subtracting a preset angle B degree to obtain a monitorable angle interval of [ A-B, A + B ]. If a is 320 degrees and B is 45 degrees, then the angle interval can be monitored as [285 °,375 ° ]. It should be noted that the size of the preset angle may be adjusted according to an actual situation, for example, the size of the preset angle may be adaptively adjusted according to the monitoring capability of the monitoring device, the terrain of the area to be monitored, and the actual situation, in an embodiment, at least the visual angle of the visual area of the camera monitoring device is over 90 degrees, and the preset angle may be set to 45 degrees.

And 420, determining the area to be surveyed by taking the area to be monitored as a center, a preset radius and a monitorable angle interval as parameters, and taking the wind direction angle as a central angle of the monitorable angle interval.
In one embodiment, the wind direction angle is the center angle of the monitorable angular interval.
With continued reference to fig. 3, the server may determine an arc using the area to be monitored as a center of a circle and using the preset radius and the preset angle as parameters, and determine the area to be surveyed according to the arc. And the wind direction angle corresponding to the average wind direction is within the angle range limited by the area to be surveyed and is the central angle of the monitorable angle interval.
In this embodiment, the range of the area to be surveyed is determined by taking the wind direction angle as the center, so that the monitoring equipment at the position of the area to be surveyed can monitor the fog in the direction of the wind direction angle in time, and further the monitoring condition of sending the fog to the area to be monitored can be ensured to be safe.
In one embodiment, calculating an average wind direction from the wind direction data comprises: acquiring fogging information corresponding to each time of fogging in the fogging data; extracting wind direction data corresponding to each piece of fogging information, and calculating an average wind direction corresponding to the fogging data according to each piece of wind direction data; and obtaining the average wind direction corresponding to the fogging data according to each average wind direction.
The fogging data comprise a plurality of fogging data records, each piece of fogging data corresponds to one wind direction data, the average wind direction corresponding to each wind direction data is extracted, and then the average wind direction of the target monitoring area within the preset time is calculated according to each average wind direction. In addition, in other embodiments, the average wind direction may be weighted according to the average wind directions at different times to obtain a weighted average wind direction, for example, the server obtains the current time and obtains the average wind direction of the fogging data corresponding to the current time, and sets the weight corresponding to the average wind direction to be the maximum.
In this embodiment, wind direction data corresponding to each fog is obtained, the mean value of the wind direction data is obtained, then the dominant wind direction is found in the plurality of wind direction mean values, the obtained dominant wind direction is set as the average wind direction, and the calculation accuracy of the average wind direction is improved.
In one embodiment, calculating an average wind direction from the wind direction data comprises: acquiring all wind direction data in the fogging data; generating a wind direction trend chart according to the wind direction data; and extracting the wind direction corresponding to the wind direction data with the maximum frequency in the wind direction trend graph as the average wind direction.
Specifically, the server obtains a trend graph corresponding to the wind direction data, and searches the most dense average wind direction in the trend graph. And obtaining the average wind direction by calculating the frequency, and obtaining the most frequent average wind direction corresponding to the region.
In one embodiment, determining the installation location of the fog monitoring device from the area to be surveyed comprises: and identifying the terrain in the area to be surveyed, and extracting the position meeting the preset terrain standard as the installation position of the fog monitoring equipment.
Specifically, the server may obtain a relief map corresponding to the area to be surveyed, identify relief information in the relief map, where the relief information may include a relief height at the location and a relief height of an area in the neighborhood of the location, and extract a location meeting a preset relief standard as an installation location of the fog monitoring device.
In one embodiment, identifying the terrain in the area to be surveyed, and extracting the position meeting the preset terrain standard as the installation position of the fog monitoring equipment comprises: acquiring satellite map data corresponding to an area to be surveyed; extracting relief information from the satellite map data; and extracting the position corresponding to the terrain information meeting the terrain standard of the fog source as the installation position of the fog monitoring equipment.
The fog source is an area where large fog easily occurs, such as a lake or a river, the server identifies the acquired satellite map data, the fog source information in the identification map can be included, information meeting the fog source standard is extracted as the installation position of the fog monitoring equipment, the server can also acquire each terrain information pre-stored in the satellite map data, and the information meeting the fog source standard is extracted as the installation position of the fog monitoring equipment.
In the embodiment, by acquiring the satellite map data, the satellite map data can provide the most accurate geographic information, so that the fog source area information in the area to be surveyed, which is acquired according to the satellite map data, is more accurate, and the fog monitoring equipment is installed according to the fog source area information, so that not only is the position automatically acquired, but also the position is accurately acquired.
In one embodiment, extracting a location corresponding to terrain information meeting the terrain standard of the fog source as an installation location of the fog monitoring device includes: extracting the position corresponding to the terrain information meeting the fog source terrain standard as a point to be surveyed; and acquiring corresponding terrain height information of the point to be surveyed, and extracting the position corresponding to the terrain height information meeting the preset standard as the installation position of the fog monitoring equipment.
In the embodiment, 2-3 camera monitoring devices are installed in a place where a valley or a river exists around the selected place and the terrain is high. And if the periphery of the searched valley or river has 2 or 3 high lands, 2 or 3 camera monitoring devices are installed. It should be noted that the monitoring device is installed at a place with a high terrain so as to maximize the view field of the 360-degree overall monitoring. The proximity of a valley or river lake is chosen because there is often sufficient water vapor to be the greatest possible source of fog.
In the embodiment, a reasonable deployment place of the monitoring equipment can be selected, so that weather-related units can monitor the generation of the foggy weather in real time, and forecast and early-warning information can be made for the people half an hour in advance.
Moreover, residents often do not live in the mountainous area, and the monitoring equipment returns data and needs a power supply, so that the camera shooting monitoring equipment is provided with a storage battery and a solar panel to solve the power supply problem.
As shown in fig. 5, a schematic flow chart of a preset radius determining method is provided, which includes:
The preset time means that after monitoring the fog and giving out early warning, personnel in the area to be monitored can take precautionary measures within the preset time so as to reduce the negative influence possibly brought by the fog. And the preset time can be adaptively adjusted according to the specific conditions of different areas to be monitored and the monitored size of the fog. For example, the server determines the preset time according to the time corresponding to different mists, or counts different areas to be monitored to determine the preset time.
In one embodiment, the preset time is 30 minutes, and the travel arrangement is made in consideration of the fact that the time of 30 minutes can meet the requirements of common people.
In step 520, an average wind speed is calculated based on the wind direction data.
The average wind speed may be determined with reference to the determination of the average wind direction, for example, wind speed data corresponding to a plurality of fogging data within a preset time may be counted, an average wind speed corresponding to a wind speed in each wind speed data is calculated, or a wind speed with the highest frequency in the wind speed data is extracted as the average wind speed, and the like, which is not limited herein.
According to the safety zone determined by the preset radius, the monitored fog does not affect people in the zone to be monitored within the preset time. Therefore, the determination of the preset radius needs to be determined according to the average wind speed and the preset time, for example, the average wind speed is multiplied by the preset time to obtain the preset radius.
If fog is detected at the distance R, the fog will drift to the area to be monitored, such as the main living area, after the time corresponding to the preset time T. The radius R is used for drawing a circle on a corresponding map to determine a region to be surveyed, so that early warning issuing can be timely performed after monitoring fog by setting monitoring equipment in the region to be surveyed, and then travel arrangement can be made for residents within a preset time T so as to reduce or avoid the influence of fog on lives of the residents.
It should be noted that the camera monitoring device faces away from the area to be monitored, such as a living area, and timely gives an early warning when fog is monitored.
Under the condition that the average wind speed is determined, the preset radius is in direct proportion to the preset time, and if the preset time is longer, the larger the preset radius is, and the larger the area to be monitored which can be covered by the camera shooting monitoring equipment is.
In mountain areas, the living area is often comparatively concentrated, and the preset time is longer, so that the preset radius is larger, the area to be covered by the camera shooting monitoring equipment is larger, and in fact, one of the purposes of arranging the camera shooting monitoring equipment is to carry out protection work for residents near the living area, so that the significance of arranging the camera shooting monitoring equipment in other remote places with less smoke is not great. In summary, the setting of the expected time is generally not suitable for being too long, as long as the safe life of residents in the living area in the concentration range can be ensured.
In another embodiment, in the process of calculating the average wind speed, the average wind speed may be weighted according to the distance from the region to be monitored, for example, the person in the region closer to the region to be monitored is dense, the weight for setting the average wind speed is smaller, and the weight for setting the average wind speed in the position farther from the region to be monitored is larger, because the wind speed corresponding to the position being more open may be larger.
In other embodiments, the size of the average wind speed may also be adaptively adjusted according to different seasons according to historical statistics data, and the like, which is not limited herein.
According to the method and the device, the preset radius is determined according to the average wind speed and the preset time, and then the safe region range corresponding to the region to be monitored is determined, so that the historical data can be reasonably utilized to provide guidance for position selection of the existing monitoring equipment, and the efficiency and the accuracy of position selection are further improved.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2-5 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
