Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 shows a hot spot distribution detection method provided in an embodiment of the present application, which reduces unnecessary time for positioning targets one by one, thereby reducing detection time for all hot spot distributions in an area and greatly improving hot spot distribution detection efficiency. Therefore, the user can quickly analyze the distribution of hot spots in the area and determine whether the hot spots nearby the place are distributed illegally. Specifically, the method may include the steps of:
step 101: detecting a hot spot based on a full-line antenna at a set central point of a target area;
step 102: respectively acquiring the hot spot intensity when traversing four edges of the target area aiming at each detected hot spot;
step 103: and judging whether the hot spot is in the target area or not according to the hot spot intensity change rule of each hot spot on each edge of the target area.
In a possible implementation, after determining that the hotspot is within the target area in step 103, the method further includes: calculating the minimum value of the hot spot intensity absolute value obtained by the hot spot in the side line field intensity container and the minimum value of the hot spot intensity absolute value obtained by the hot spot in the line field intensity container at the opposite side; further, calculating the actual physical position distribution of the hot spot according to the ratio of the two absolute minimum values and the actual physical length in the target area.
In a possible implementation manner, in step 103, the determining, by the server, whether a hotspot is located in the target area according to a hotspot intensity variation rule of each hotspot on each edge of the target area includes: determining the variation track of the hot spot intensity of each hot spot on each edge of the target area; determining the hot spot in the target area, wherein the change track of the hot spot strength of each edge is increased and then decreased; and determining the hot spot which does not meet the change track of the hot spot strength of each edge and is larger and then 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 the hot spot in the target area, the true value of the field intensity is negative, the field intensity trajectory is first increased and then decreased, but the absolute value is first decreased and then increased.
The antenna is a device divided into an omni-directional antenna and a directional antenna. The directional antenna can accurately collect targets in a sector range of about 90 degrees on the front surface of the antenna. The omni-directional antenna may cover a target within 360 degrees of the perimeter. The embodiment of the application adopts the omnidirectional antenna for detection, and realizes more comprehensive and more accurate hotspot detection.
The closer the wireless network card is to the hot spot, the higher the corresponding strength is, and the farther the wireless network card is from the hot spot, the lower the corresponding strength is; when the hot points are in a vertical relation around the region, the corresponding hot point field intensity is the largest during the sideline scanning. That is, a hot spot in the region starts from one corner of the region to another corner along the side line of the region, and the hot spot signal is maximum when the hot spot is perpendicular to the hot spot, and the total is in an inverted V trend. In the embodiment of the application, the step is performed on all four edge lines of the target area, if all the four edge lines meet the rule, the hot spot can be judged to be an intra-area hot spot, and then the coordinate position of the hot spot in the area is calculated based on an intra-area distribution algorithm according to the minimum value obtained from the four edge lines. That is, the minimum absolute value taken in the edge field strength container according to the hot spot and the minimum absolute value in the corresponding other edge container (e.g., left and right, top and bottom). And obtaining the actual physical position distribution in the direction according to the ratio of the two values and the actual physical length in the region, wherein the left-right direction and the front-back direction are the same.
For the hot spot outside the area, two edge lines and the hot spot trend are in a rule that the intensity list collected by the hot spot is gradually increased or gradually reduced, and the trend that the intensity list is increased and then reduced does not exist. Hot spots are excluded from the area according to this.
In summary, the hot spot distribution detection method provided in the embodiment of the present application adopts the device capable of acquiring the hot spot intensity to acquire all hot spots at the central position of the area, so that the final calculation is facilitated to be performed according to the hot spot list. And further, walking along the first edge of the area step by step, collecting the intensity lists of all hot spots of the sideline and storing the intensity lists into a memory. The other three directions are the same. And thirdly, analyzing data, namely extracting a data list in each direction from the hot spots one by one, analyzing whether the track of the list data conforms to the inverted V trend, increasing the intensity in the list and then decreasing the intensity, and if the track in the list changes singly, the track can be judged to be out of the area because the hot spots are in a relationship of gradually increasing or decreasing outside the area. For example, as shown in fig. 2, the following steps can be performed:
step 1: acquiring all hot spots in the range of the full-line antenna at the central point of the target area, such as a hot spot 1, a hot spot 2, a hot spot 3, a hot spot … … and a hot spot 8;
step 2: acquiring the hot spot intensity of the full-line antenna walking along the left side of the area;
and step 3: acquiring the hot spot strength of the whole-line antenna walking along the upper edge of the area;
and 4, step 4: acquiring the hot spot strength of the whole-line antenna walking along the right side of the area;
And 5: acquiring the walking hot spot strength below the full-line antenna area;
step 6: sequentially extracting each side line data list of each hotspot;
and 7: performing track analysis on the four lists; judging whether the region belongs to the marked region, if so, executing the step 8; if not, executing step 9;
and 8: judging that the intensity tracks of the 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;
and 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 not in accordance with the conditions, and marking the hot spots as out-of-area.
Therefore, the method provided by the embodiment of the application can enable a user to quickly analyze the distribution of hot spots in the area, can further analyze whether illegal hot spots are distributed near a place, timely eliminates harm, reduces loss and ensures the safety of a wireless environment.
In summary, the embodiment of the present application provides a hot spot distribution detection method, which detects a hot spot based on a full line antenna by setting a central point in a target area; respectively acquiring the hot spot intensity when traversing four edges of the target area aiming at each detected hot spot; and judging whether the hot spot is in the target area or not according to the hot spot intensity change rule of each hot spot on each edge of the target area.
