[0039] Embodiment 1

[0040] like Figure 1 As shown, the signal strength monitoring method includes the following steps:

[0041] S101. A monitoring plane 151 is set in a monitoring area 15; a moving trajectory is planned for each of the plurality of flight monitoring devices in the monitoring plane; the intersection of any two moving trajectories on the monitoring plane is used as a first signal strength measurement point; a plurality of communication base stations 16 are set in the monitoring area 15, the monitoring plane is parallel to and higher than the ground plane, and any two moving trajectories on the monitoring plane have an intersection on the monitoring plane;

[0042] S102. Each flight monitoring device moves along the corresponding movement trajectory in the monitoring plane;

[0043] Each flight monitoring device detects and obtains the base station signal strength value of each first signal strength measurement point on the corresponding moving trajectory on the monitoring plane;

[0044] The average value of the base station signal strength values ​​detected by each flight monitoring device at the same first signal strength measurement point is taken as the first base station signal strength value of the first signal strength measurement point to obtain the first base station signal strength value of each first signal strength measurement point.

[0045] Figure 2The implementation scenario of the signal strength monitoring method is shown, including a server 11 and a mobile vehicle 13, and the server 11 and the mobile vehicle 13 communicate through a network 12. Among them, the mobile vehicle 13 is a carrying tool of the flight monitoring device. When the flight monitoring device is hovering in the air, the flight monitoring device and the mobile vehicle 13 communicate through wireless signals. Two flight monitoring devices are set in the monitoring area 15, namely the first drone 141 and the second drone 142. The base station signal strength value above the monitoring area 15 is detected by the first drone 141 and the second drone 142. When the first drone 141 and the second drone 142 are working, information interaction is achieved between the mobile vehicle 13 through wireless signals. The base station signal strength value located in the space of the monitoring area 15 is detected by the first drone 141 and the second drone 142 as flight monitoring devices. The server 11 can be, but is not limited to, an electronic device that can automatically perform numerical calculations and information processing according to the instructions set or stored, and its hardware includes, but is not limited to, a microprocessor, an application-specific integrated circuit (ASIC), a programmable logic device (PLD), a field programmable gate array (FPGA), a digital signal processor (DSP), and an embedded device. The server 11 may also be a desktop computer, a network host, a single network server, a cluster of multiple network servers, or a cloud composed of multiple servers; here, the cloud is composed of a large number of computers or network servers based on cloud computing, where cloud computing is a type of distributed computing, a virtual supercomputer composed of a group of loosely coupled computers. The network 12 may include, but is not limited to, the Internet, a wide area network, a metropolitan area network, a VPN network, a wireless self-organizing network (Ad Hoc network), etc.

[0046] Figure 3 The monitoring plane 151 is a schematic diagram of the monitoring plane 151, which is arranged in the monitoring area 15. The monitoring plane 151 is located in the space above the ground plane of the monitoring area 15, and the outer contour of the monitoring plane 151 is the same as the plane contour of the monitoring area 15. A moving trajectory is planned for each flight monitoring device in the monitoring plane 151. Figure 3The monitoring plane 151 shown in the figure has a first moving track 1511 and a second moving track 1512 planned. The first drone 141 flies along the first moving track 1511, and the second drone 142 flies along the second moving track 1512. The first drone 141 and the second drone 142 fly along different moving tracks respectively. The intersection of any two moving tracks is extracted as the first signal strength measurement point 1513 of the flight monitoring device. The principle of extracting the intersection of any two moving tracks is that each moving track is in a monitoring plane 151, and the moving tracks are not straight lines parallel to each other, and the moving tracks can be curves, broken lines, etc. When the flight monitoring device passes through the intersection, the signal strength can be measured. Specifically, the first moving track 1511 and the second moving track 1512 are both broken lines, and can also be other forms of curves or straight line tracks. There are multiple intersections between the first moving track 1511 and the second moving track 1512 in the monitoring plane 151, and the intersection is the first signal strength measurement point 1513. Each flight monitoring device moves along the corresponding moving track in the monitoring plane 151. The first drone 141 as the flight monitoring device flies along the first moving track 1511, and the second drone 142 flies along the second moving track 1512. Each flight monitoring device detects and obtains the signal strength value of each first signal strength measurement point 1513 on the moving track corresponding to it, and takes the average of all the corresponding signal strength values ​​of all the first signal strength measurement points 1513 as the first base station signal strength value. When the first drone 141 flies along the first moving track 1511 and passes through each first signal strength measurement point 1513 in the monitoring plane 151, the signal strength value at the first signal strength measurement point 1513 is detected, for example, the signal strength value of a certain first signal strength measurement point 1513 is -60dbm. When the second drone 142 flies along the second moving track 1512 and passes through each first signal strength measurement point 1513 in the monitoring plane 151, the signal strength value at the first signal strength measurement point 1513 is detected, for example, the signal strength value of a certain first signal strength measurement point 1513 is -65dbm. At the same first signal strength measurement point 1513, the signal strength value detected by the first drone 141 is -60dbm, and the signal strength value detected by the second drone 142 is -65dbm, so the first base station signal strength value of the first signal strength measurement point 1513 is -62.5dbm (average value, i.e. -60dbm+-60dbm=-62.5dbm). Each first signal strength measurement point 1513 in the monitoring plane 151 generates a first base station signal strength value.

[0047] Preferably, step S103 is performed after step S102 to obtain a base station signal strength gradient map of the monitoring plane of the monitoring area by fitting according to the first base station signal strength values ​​of each first signal strength measurement point in the monitoring plane within the monitoring area. Figure 4 The base station signal strength gradient map of the monitoring plane 151 of the monitoring area 15 is obtained by fitting the first base station signal strength value of the first signal strength measurement point 1513 in the monitoring plane 151 in the monitoring area 15. The signal strength values ​​of each first signal strength measurement point 1513 are collected by the first drone 141 and the second drone 142, and the first base station signal strength value of each first signal strength measurement point 1513 is obtained by taking the average. After data fitting, it is possible to obtain, for example Figure 4 The isovalue lines 1514, 1515, and 1516 are shown in FIG. 1. The signal strength of any point in the space above the monitoring area 15 can be obtained through the base station signal strength isovalue surface.

[0048] The signal strength monitoring method of the first embodiment sets a monitoring plane above the communication base station in the monitoring area, and then flies along the moving trajectory in the monitoring plane through a flight monitoring device (such as a drone), obtains the base station signal strength value of the signal strength measurement point during the flight, and then obtains the base station signal strength gradient map of the monitoring plane according to these base station signal strength values. The signal strength monitoring method can understand the base station signal strength value of each point in the space in real time, and then provide a data basis and reference for understanding and optimizing the signal strength in the entire space. It is possible to screen out the area that meets the temporary sudden gathering of large user personnel, that is, the area to be reinforced, by detecting the load value of the wireless communication base station, and use the area to be reinforced with the largest load as the reinforcement area, and then obtain the sub-reinforcement area according to the distribution of mobile terminals in the reinforcement area, and then obtain the preferred reinforcement point according to the sub-reinforcement area as the hovering point of the flight monitoring device, and use the flight monitoring device to provide wireless communication services for mobile terminals in the reinforcement area, thereby improving the communication rate of the mobile terminals in the reinforcement area.

[0049] Embodiment 2

[0050] Based on the signal strength monitoring method of the first embodiment, in step S101, a first reinforcement plane 152 and a second reinforcement plane 153 are further provided in the monitoring area, and the first reinforcement plane 152 and the second reinforcement plane 153 are located between the monitoring plane 151 and the ground plane. Figure 5 As shown;

[0051] Planning a moving trajectory for each flight monitoring device on the first reinforcement plane 152 and the second reinforcement plane 153 respectively;

[0052] The intersection of any two moving tracks on the first reinforcement plane 152 is used as the second signal strength measurement point 1523;

[0053] The intersection of any two moving tracks on the second reinforcement plane 153 is used as the third signal strength measurement point 1533;

[0054] Any two moving tracks on the first reinforcement plane have an intersection on the first reinforcement plane; any two moving tracks on the second reinforcement plane have an intersection on the second reinforcement plane.

[0055] like Figure 6 As shown, a third moving trajectory 1521 and a fourth moving trajectory 1522 are planned in the first reinforcement plane 152. The third moving trajectory 1521 of the first UAV 141 and the fourth moving trajectory 1522 of the second UAV 142 are located in the first reinforcement plane 152. The intersection of the third moving trajectory 1521 and the fourth moving trajectory 1522 is used as the second signal strength measurement point 1523 in the first reinforcement plane 152.

[0056] like Figure 7 As shown, the fifth moving track 1531 and the sixth moving track 1532 are planned in the second reinforcement plane 153; the fifth moving track 1531 of the first UAV 141 and the sixth moving track 1532 of the second UAV 142 are in the second reinforcement plane 153. The intersection of the fifth moving track 1531 and the sixth moving track 1532 is used as the third signal strength measurement point 1533 in the second reinforcement plane 153.

[0057] In step S102, each flight monitoring device also moves along the corresponding movement tracks in the first reinforcement plane 152 and the second reinforcement plane 153;

[0058] Each flight monitoring device also detects and obtains the base station signal strength value of each second signal strength measurement point on the first reinforcement plane and the corresponding moving trajectory, and detects and obtains the base station signal strength value of each third signal strength measurement point on the second reinforcement plane and the corresponding moving trajectory;

[0059] Taking the average value of the base station signal strength values ​​detected by each flight monitoring device at the same second signal strength measurement point as the second base station signal strength value of the second signal strength measurement point, and obtaining the second base station signal strength value of each second signal strength measurement point;

[0060] The third base station signal strength value of each third signal strength measurement point is obtained by taking the average value of the base station signal strength values ​​detected by each flight monitoring device at the same third signal strength measurement point as the third base station signal strength value of the third signal strength measurement point.

[0061] like Figure 6 As shown, the first UAV 141 and the second UAV 142 as flight monitoring devices first fly along their respective moving trajectories, namely the third moving trajectory 1521 and the fourth moving trajectory 1522, in the first reinforcement plane 152. Figure 7 As shown, the first UAV 141 and the second UAV 142 fly along their respective moving trajectories in the second reinforcement plane 153 , that is, along the fifth moving trajectory 1531 and the sixth moving trajectory 1532 .

[0062] like Figure 6 , Figure 7 As shown, the first drone 141 and the second drone 142 fly in the first reinforcement plane 152, obtain the signal strength value of each second signal strength measurement point 1523 in the first reinforcement plane 152, and then take the average of the two signal strength values ​​of the same second signal strength measurement point 1523 as the second base station signal strength value of the second signal strength measurement point 1523. For example, the signal strength values ​​detected by the first drone 141 and the second drone 142 at the same second signal strength measurement point 1523 are -45dbm and -50dbm respectively, then the second base station signal strength value of the second signal strength measurement point 1523 is -47.5dbm. Similarly, in the second reinforcement plane 153, the first drone 141 and the second drone 142 can obtain the third base station signal strength value of each third signal strength measurement point 1533 in the second reinforcement plane 153 by monitoring at each third signal strength measurement point 1533.

[0063] Preferably, step S103 is performed after step S102, and multiple base station signal strength gradient maps of the monitoring area are obtained by fitting based on the first base station signal strength value of the first signal strength measurement point 1513 in the monitoring plane 151 in the monitoring area, the second base station signal strength value of the second signal strength measurement point 1523 in the first reinforcement plane 152, and the third base station signal strength value of the third signal strength measurement point 1533 in the second reinforcement plane 153. Multiple base station signal strength isosurfaces can be formed in the space above the monitoring area 15, and the signal strength of any point in the space above the monitoring area 15 can be obtained through the base station signal strength isosurfaces.

[0064] In some embodiments, the monitoring plane 151, the first reinforcement plane 152, and the second reinforcement plane 153 are respectively associated with a plane ID (identification code), and the base station signal strength value of each signal strength measurement point, the position information of the signal strength measurement point, and the plane ID constitute a signal strength array. For example, the plane ID of the monitoring plane 151 is 01, the plane ID of the first reinforcement plane 152 is 02, and the plane ID of the second reinforcement plane 153 is 03. The position information (position information in the relative coordinate system) of the signal strength measurement point in the monitoring plane 151 is (2.3344, 3.21434, 4.13455), and the base station signal strength value is -45dbm, then the signal strength array of the signal strength measurement point is (02, 2.3344, 3.21434, 4.13455, 45).

[0065] According to the signal strength array, multiple base station signal strength gradient maps within the monitoring area 15 are obtained by fitting. According to the signal strength array, the space above the monitoring area 15 can be fitted to obtain the base station signal strength isosurface.

[0066] In some embodiments, multiple planes may be provided, not only the monitoring plane 151, the first reinforcement plane 152, and the second reinforcement plane 153. In each plane, multiple drones may be used for measurement, and each drone has an independent moving track. In this way, more sampling points may be obtained in the space above the monitoring area 15, thereby improving the fitting accuracy.

[0067] The signal strength monitoring method of embodiment 2 sets a first reinforcement plane 152 and a second reinforcement plane 153 between the monitoring plane 151 and the ground surface, and uses a flight monitoring device to fly along corresponding moving trajectories in the two reinforcement planes, and obtains the base station signal strength values ​​of the signal strength measurement points during the flight, and then obtains the base station signal strength isosurface in the space corresponding to the entire monitoring area based on these base station signal strength values; the base station signal strength value of each point in the space can be understood in real time through the base station signal strength gradient map and the base station signal strength isosurface, and then the communication base stations can be added or the positions of the existing communication base stations can be adjusted to optimize the signal strength in the entire space and improve the user experience.
