Method, device and system for adjusting antenna angle

Abstract

The invention relates to the technical field of antennas, and discloses a method, device and system for adjusting an antenna angle, and the method comprises the steps: obtaining an initial RSSI value; taking the initial value of i as 1, generating an adjustment instruction according to the i-th rotation step length, and sending the adjustment instruction to a motor control module, so that the motor control module controls an antenna to rotate according to the adjustment instruction and a pre-configured motion control model; obtaining an RSSI value after the antenna is rotated, and calculating a difference value between the initial RSSI value and the RSSI value after the antenna is rotated; updating the ith rotation step length to obtain an (i + 1) th rotation step length; judging whether an iteration termination condition is met or not, and if yes, ending antenna angle adjustment; and if not, adding one to i, and returning to the step of generating the adjustment instruction according to the i-th rotation step length and sending the adjustment instruction to the motor control module. According to the method, a better position of the RSSI can be found by using a small number of iterations, so that an angle with a stronger antenna signal can be quickly found.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a method, device and system for adjusting an antenna angle. Background technique [0002] At present, most home wireless routers use omnidirectional antennas. In actual use, antenna radiation is not ideally omnidirectional, but there are dominant and inferior radiation directions. When the client is in the dominant radiation direction of the antenna, the signal strength is higher and the experience is better. Therefore, in order to improve the communication quality, it is necessary to adjust the radiation direction of the antenna so that the dominant radiation direction of the antenna faces the client, so as to improve the experience of the client. [0003] In the prior art, a common method is to adjust the coverage angle of the antenna by mechanically rotating the antenna. In one implementation, the user adjusts by manually rotating the antenna, which is not adjusted...

Problems solved by technology

However, due to the need to traverse the relationship between angles and parameters, the entire process takes a long time, resulting in poor real-time adjustment of angles and affecting user experience

[0004] To sum up, the way of adjusting the antenna coverage angle in the prior art has poor adjustment effect or poor real-time performance, which affects user experience
