Detailed Description
Other advantages and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, by way of illustration, is to be read in connection with certain specific embodiments, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 shows a method for detecting hot spot distribution, which reduces unnecessary time for locating targets one by one, thereby reducing detection time of all hot spot distribution in an area and greatly improving efficiency of hot spot distribution detection. The user can rapidly analyze the hot spot distribution in the area and analyze whether illegal hot spot distribution exists near the site. Specifically, the method comprises the following steps:
step 101: detecting a hot spot based on an omnidirectional antenna at a set center point of a target area;
step 102: aiming at each detected hot spot, respectively acquiring hot spot intensity when traversing four sides of the target area;
step 103: and judging whether the hot spot is in the target area according to the hot spot intensity change rule of each hot spot on each side of the target area.
In one possible implementation, after determining that the hot spot is within the target area in step 103, the method further includes: calculating the minimum value of the absolute value of the hot spot intensity obtained from the hot spot in the boundary line field intensity container and the minimum value of the absolute value of the hot spot intensity obtained from the boundary line field intensity container; further, according to the ratio of the minimum values of the two absolute values and the actual physical length in the target area, the actual physical position distribution of the hot spot is calculated.
In a possible implementation manner, in step 103, the determining, by the server, whether the hot spot is in the target area according to a hot spot intensity variation rule of each hot spot on each side of the target area includes: determining a change track of the hot spot intensity of each hot spot on each side of the target area; the hot spot with the change track of the hot spot intensity of each side being enlarged and then reduced is judged to be the hot spot in the target area; and judging the hot spot which does not meet the change track of the hot spot intensity of each side and is larger and smaller as the hot spot outside the target area. .
When the hot spot is vertical to the side line, the distance is minimum, the field intensity is maximum, and the absolute value of the field intensity is minimum. Therefore, when determining hot spots in the target area, the true value of the field strength is a negative number, the field strength trajectory is first increased and then decreased, but the absolute value is first decreased and then increased.
Antennas are devices that are classified into omni-directional antennas and directional antennas. The directional antenna can accurately collect targets in a fan-shaped range of about 90 degrees on the front surface of the antenna. An omni-directional antenna may cover a target within 360 degrees of the perimeter. The embodiment of the application adopts the omni-directional antenna to detect, thereby realizing more comprehensive and more accurate hot spot detection.
The closer the wireless network card is to the hot spot, the higher the corresponding intensity, the farther the wireless network card is to the hot spot, and the lower the corresponding intensity; when the periphery of the area is in a vertical relation with the hot spot, the corresponding hot spot field intensity is maximum during the boundary scanning. That is, a hot spot is in a region, and starts from one corner of the region to the other corner along the region boundary, and the hot spot signal is maximum when the hot spot signal is perpendicular to the hot spot, so that the trend is generally inverted V. In the embodiment of the application, the step is performed on all four edges of the target area, if the rule is met, the hot spot can be judged to be the hot spot in the area, and then the coordinate position of the hot spot in the area is calculated based on the intra-area distribution algorithm according to the minimum value obtained from the four edges. That is, the minimum absolute value obtained in the boundary field strength bin based on the hot spot and the absolute minimum value in the corresponding other boundary bin (e.g., left and right, upper and lower). And obtaining the actual physical position distribution of the direction according to the ratio of the two values and the actual physical length in the area, wherein the left-right direction and the front-back direction are the same.
For hot spots outside the area, two side lines and hot spot trends form a rule that the intensity list collected by the hot spot gradually becomes larger or smaller, and no trend of first becoming larger or smaller exists. According to this situation, the hot spot is eliminated in the area.
In summary, in the method for detecting the distribution of the hot spots provided by the embodiment of the application, all the hot spots are collected at the central position of the area by adopting the equipment capable of collecting the intensity of the hot spots, so that the final calculation is convenient and the calculation is performed according to the hot spot list. Further, walking gradually along the first edge of the area, collecting intensity lists of all hot spots of the edge, and storing the intensity lists into a memory. The other three directions are the same. Thirdly, data analysis, namely extracting a data list of each direction from the hot spot one by one, and making track analysis on list data whether the track analysis accords with the inverted V trend or not, wherein the strength in the list is increased and then decreased, and if the track change in the list is single, the hot spot is in a gradually-increasing or gradually-decreasing relation outside the area, the hot spot can be judged to be outside the area. For example, the following steps may be performed as shown in fig. 2:
step1: acquiring all hot spots, such as hot spot 1, hot spot 2, hot spots 3, … … and hot spot 8, in the range of the omnidirectional antenna at the central point of the target area;
step 2: acquiring the hot spot intensity of the omnidirectional antenna walking along the left side of the area;
step 3: acquiring the hot spot intensity of the omnidirectional antenna walking along the upper edge of the area;
step 4: acquiring the hot spot intensity of the omnidirectional antenna walking along the right side of the area;
Step 5: acquiring the hot spot intensity of walking below the omnidirectional antenna area;
step 6: sequentially extracting each side line data list of each hot spot;
step 7: track analysis is carried out on the four lists; judging whether the target area belongs to the labeling area, if so, executing the step 8; if not, executing the step 9;
Step 8: judging that the intensity tracks of four lists of the hot spots 2,3, 6 and 7 meet the conditions, marking the hot spots as areas, and calculating the coordinate distribution of the hot spots;
step 9: and judging that the intensity tracks of the four lists of the hot spot 1, the hot spot 4, the hot spot 5 and the hot spot 8 are found to be out of the area, and marking the hot spots as outside the area.
It can be seen that the method provided by the embodiment of the application can enable the user to rapidly analyze the hot spot distribution in the area, further analyze whether the illegal hot spot distribution exists near the exit, eliminate harm in time and reduce loss, and ensure the safety of the wireless environment.
In summary, the embodiment of the present application provides a method for detecting hot spot distribution, which detects hot spots based on omni-directional antennas by setting a center point in a target area; aiming at each detected hot spot, respectively acquiring hot spot intensity when traversing four sides of the target area; and judging whether the hot spot is in the target area according to the hot spot intensity change rule of each hot spot on each side of the target area. Unnecessary time for positioning targets one by one is reduced, detection time of all hot spot distribution in the area is reduced, and the efficiency of hot spot distribution detection is greatly improved.
