In the operation steps of the above embodiment, when the intelligent terminal receives an instruction for starting the lifting camera, the intelligent terminal controls the lifting camera to rise to a predetermined position, and after the lifting camera reaches the predetermined position, a functional antenna on the lifting camera is in circuit connection with a radio frequency WiFi circuit module arranged inside the intelligent terminal main body, a connection signal is sent to the router through the functional antenna, and after the router receives the connection signal, a mode of a release signal of the router is started to be a beam function.
Specifically, the intelligent terminal controls the lifting camera to ascend a preset distance, the preset distance is a distance from the antenna feed point on the lifting camera to the radio frequency WiFi circuit module, when the lifting camera ascends to a preset position, the antenna feed point of the functional antenna on the lifting camera slides to a position where the radio frequency WiFi circuit module is located inside the intelligent terminal and is in circuit connection with the radio frequency WiFi circuit module, therefore, the intelligent terminal can conduct signals to the functional antenna through the radio frequency WiFi circuit module and send connection signals to the router through the functional antenna on the lifting camera, and the functional antenna can achieve the effects of sending and receiving signals and establishing connection with wireless WiFi.
The beam function concentrates electromagnetic wave energy in the antenna in a certain direction through a beam forming technology, the direction can also be called a main lobe, a signal received by equipment positioned on the main lobe is strong, the energy of electromagnetic wave radiation in other directions is relatively reduced, in the conventional router for transmitting electromagnetic waves, the omnidirectional radiation of the antenna is generally adopted, namely the electromagnetic wave transmission intensity in a 360-degree range is the same, and in the invention, the electromagnetic wave energy in a certain range is concentrated through the beam forming technology, so that the effect of data transmission stability is improved.
When the router receives the connection signal, the router antenna rotates while the beam function is started, the rotation range is 360 degrees, in order to avoid overlong waiting time of a user, a first preset time is preset in the invention, and in the first preset time, the router antenna rotates 360 degrees on the router, and the direction pointed by the router antenna is the same as the beam range, so that when the direction pointed by the router antenna is the direction of the intelligent terminal of the user, the intensity of wireless connection is maximum, and the user can obtain more stable wireless data connection.

and S430, controlling the router antenna to rotate according to the optimal angle.
In the invention, a time-angle mapping table is preset in the router, after the router receives the information of the strongest signal time period, the information is compared with the time-angle mapping table, so that the optimal angle corresponding to the information of the strongest signal time period is obtained, namely, the strongest signal position of the wireless connection between the router antenna and the intelligent terminal is established, after the optimal angle is obtained, the router antenna rotates to the position where the preset angle is located, and after the action is completed, the router antenna improves the electromagnetic wave energy radiation intensity through the wave beam function and simultaneously corresponds to the position where the intelligent terminal is located, thereby realizing the effect of improving the WiFi connection strength of the intelligent terminal.
