Background
Wireless bridge devices are typically not connected by physical media, but by radio waves that are invisible to the human eye. There is a certain difficulty in installation and debugging when both wireless bridge devices are not visible. When data is transmitted over a long distance, especially after exceeding 10km, the orientation of the opposite equipment cannot be seen by human eyes, and the opposite equipment cannot be seen by shielding. Fig. 1 is a diagram of a forest scene, in which a wireless bridge a and a wireless bridge B are separated by 10km, and a wireless bridge D and a wireless bridge E are hidden in a tree, and it takes a long time to debug and associate a and B, C and D and C and E when wireless association is needed.
After the general constructors associate the wireless devices in a wireless manner, time is not taken to accurately adjust the signal strength between the wireless devices, so that the wireless devices do not exert the maximum performance. And as the distance between the wireless devices increases, the narrower the range of the antenna beam used, the greater the difficulty of debugging.
Therefore, a method for connecting a bridge is needed to ensure the strongest signal of the connection between two wireless devices.

Fig. 2 is a flowchart of a bridge connection method according to an embodiment of the present invention, and as shown in fig. 2, the method includes:
s1, acquiring theoretical signal strength between two target bridges;
the target bridge is a bridge which needs to be angle-debugged, and in reality, the target bridge is generally installed at two different places, and the theoretical signal intensity between the two target bridges is calculated according to the actual position of the target bridge.
S2, acquiring the optimal pitch angle corresponding to each target network bridge according to the corrected altitude of each target network bridge;
specifically, when the actual distance between two target bridges exceeds a certain threshold, the signal transmission between the target bridges may be blocked by the earth due to the arc shape of the earth, and therefore, in this case, the altitude of the target bridge needs to be corrected, that is, a certain height is added to the original altitude.
If the actual distance between the two target bridges does not exceed the threshold, the signal transmission between the two target bridges is not blocked by the earth, so the altitude of the target bridge after correction is the original altitude of the target bridge.
And calculating the optimal pitch angle corresponding to each target network bridge according to the corrected altitude of the two target network bridges.
And S3, setting the actual pitch angles of each target network bridge as corresponding optimal pitch angles respectively, displaying the directions of the actual pitch angles of the two target network bridges in a preset map in real time, and if the difference value between the actual signal intensity and the theoretical signal intensity of the two target network bridges is out of a preset error, adjusting the actual pitch angle of any target network bridge according to the directions of the actual pitch angles of the two target network bridges in the preset map until the difference value between the actual signal intensity and the theoretical signal intensity of the two target network bridges is within the preset error.
In the actual situation, due to various interferences and noises, even if the actual pitch angle of each target network bridge is set at the optimal pitch angle, the actual signal strength between two target network bridges is not necessarily the strongest, and therefore, the pitch angle of the target network bridge needs to be adjusted.
The actual signal strength between two target bridges at the optimal pitch angle is calculated first, the error between the actual signal strength and the theoretical signal strength is calculated, and if the error is beyond the preset error, it indicates that the actual pitch angle of the target bridge needs to be adjusted.
The direction of the actual pitch angle of each target network bridge is displayed in real time in the preset map, so that the actual pitch angle of any one target network bridge is adjusted according to the direction until the actual signal strength between the two target network bridges is within the preset error.
The network bridge connection method provided by the embodiment of the invention provides a convenient method for the target network bridge to be installed and debugged outdoors, and when the two target network bridges are invisible, only an installer needs to debug according to the direction of the target network bridge displayed on a preset map, so that the debugging mode is visual, simple and convenient.

and if the difference value between the actual signal intensity and the theoretical signal intensity between the two target bridges is within the preset error, the connecting line between the two target bridges is in another fixed color.
Specifically, on the preset map, in addition to the direction of the actual pitch angle of the two target bridges, the connection line between the two target bridges is also displayed in real time, and the color of the connection line is adjusted according to the error relationship between the actual signal intensity and the theoretical signal intensity.
Specifically, when the error between the actual signal strength and the theoretical signal strength is outside the preset error, the connecting line between the two target bridges is in a certain color, and when the error between the actual signal strength and the theoretical signal strength is within the preset error, the connecting line between the two target bridges is in another color, so that when the actual pitch angle of the target bridges is adjusted, whether the actual pitch angle of the target bridges meets the requirement or not can be visually seen.
On the basis of the foregoing embodiment, preferably, the obtaining of the theoretical signal strength between two target bridges is specifically obtained by:
and acquiring the theoretical signal intensity between the two target bridges according to the line-of-sight distance between the two target bridges, the transmitting power of each target bridge, the antenna gain of each target bridge and the beam range of each target bridge.
Specifically, the line-of-sight distance between two target bridges refers to a distance in the horizontal line direction, and the theoretical signal strength between the two target bridges is calculated according to the line-of-sight distance between the two target bridges, the transmission power of each target bridge, the antenna gain of each target bridge, and the beam range of each target bridge.
On the basis of the above embodiment, preferably, the line-of-sight distance between the two target bridges is obtained by:
and acquiring the line-of-sight distance between the two target bridges according to the actual positions of the two target bridges.
Specifically, the line-of-sight distance between two target bridges is calculated from the actual positions of the two target bridges, which are typically referred to as the actual coordinate positions of the target bridges.

On the basis of the above-described embodiments, the modified altitude of each target bridge is preferably obtained from the actual position of each target bridge and the actual altitude of each target bridge.
As described above, if the actual positions of the two target bridges are too far apart, and the signal transmission between the target bridges is blocked by the earth surface, the actual altitude of the target bridges is corrected, and a section of height threshold is added on the basis of the actual altitude of the target bridges to obtain the corrected altitude; if the actual positions of the two target bridges are closer, the actual altitude of the target bridge is the corrected altitude.
