Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
The embodiment of the present application provides a wireless terminal device, which has a structure as shown in fig. 1 and at least includes a wireless communication module 110, a motor 120, a rotation mechanism 130, a directional antenna 140, a power supply module 150, and the like. The power supply module is used for supplying power to the wireless communication module and the motor, and the motor is used for driving the rotating mechanism to rotate under the control of the wireless communication module; the rotating mechanism is driven by the motor to rotate so as to drive the directional antenna to rotate synchronously; the directional antenna is used for receiving and transmitting wireless signals; the wireless communication module is used for controlling the orientation of the directional antenna by adopting a corresponding antenna control method, so that the directional antenna can be in the optimal orientation, the requirements of wireless networks such as 3G/4G/5G and the like on communication functions are met, and the transmission performance can be optimal through automatic adjustment.
In some embodiments of the present application, the wireless communication module may adopt any General wireless communication module, and generally has a control Interface such as GPIO (General-Purpose Input/Output) or MIPI (Mobile Industry Processor Interface), and may calculate according to a preset algorithm by using the uplink and downlink transmission rate and the auxiliary parameter of the directional antenna, and control the motor according to the calculation result, without any other special requirements.
The motor can include at least one controllable rotating electrical machines, uses control signals such as GPIO, MIPI, and the direction and the speed of motor rotation are controlled for the corresponding rotary mechanism of motor drive drives directional antenna synchronous rotation to specific orientation. In practical scenarios, at least one motor may be responsible for the rotation of the directional antenna in the horizontal direction, and other motors may also be responsible for the rotation in the vertical direction or other directions. The rotating mechanism can be connected with a motor and a directional antenna by specifically using a gear or a conveyor belt and the like to realize transmission. Accordingly, at least one set of rotation mechanism may be connected to the motor and the directional antenna to rotate the antenna in the horizontal direction, and another rotation mechanism may be provided to rotate the directional antenna in the vertical direction or more.
For example, in some embodiments of the present application, the motors include a first motor that controls rotation in a horizontal direction and a second motor that controls rotation in a vertical direction, and the rotation mechanism includes a horizontal rotation mechanism and a vertical rotation mechanism. The horizontal rotating mechanism is used for rotating in the horizontal direction under the driving of the first motor so as to drive the directional antenna to rotate synchronously, and the vertical rotating mechanism is used for rotating in the vertical direction under the driving of the second motor so as to drive the directional antenna to rotate synchronously, so that the orientation control of the directional antenna in two directions is realized.
The directional antenna comprises at least more than one directional antenna array, the main lobe direction angles of the directional antenna arrays are consistent, and the number and the supporting frequency range of specific antenna ports are determined by the antenna port requirements of the wireless communication module.
The power supply module can comprise a direct current power supply transmission circuit and supplies power to the wireless communication module and the motor part.
Fig. 2 shows a processing flow of an antenna control method of a wireless terminal device in an embodiment of the present application, which includes at least the following processing steps:
step S201, the wireless communication module controls the motor to drive the rotating mechanism to rotate in a preset horizontal direction, so that the directional antenna and the rotating mechanism rotate synchronously.
The preset horizontal direction can be a forward rotation direction or a reverse rotation direction of the motor, and can be set according to the requirements of an actual scene. For example, in this embodiment of the present application, the wireless communication module may control the first motor rotating in the horizontal direction to rotate in the forward direction, so that the first motor drives the rotating mechanism to rotate in the forward direction, and at this time, the directional antenna also rotates in the forward direction along with the rotation mechanism synchronously. During the rotation process of the directional antenna, the orientation of the directional antenna changes, so that the transmission quality of signals between the directional antenna and the communication opposite end changes synchronously.
Step S202, the wireless communication module obtains the uplink and downlink transmission rate and the auxiliary parameter of the directional antenna in the horizontal rotation process, and calculates the transmission quality reference value under the corresponding horizontal rotation angle according to the uplink and downlink transmission rate and the auxiliary parameter.
In an actual scene, the angular speed of the motor driving the special selection mechanism during rotation may adopt a fixed numerical value, or may be controlled by the wireless communication module through a control instruction. When the wireless communication module obtains the uplink and downlink transmission rates and the auxiliary parameters of the directional antenna in the horizontal rotation process, the wireless communication module can set a proper sampling frequency according to the rotation angular speed to sample the uplink and downlink transmission rates and the auxiliary parameters. For example, the uplink and downlink transmission rates and the auxiliary parameters may be sampled at certain rotation angle intervals (e.g., every 5 ° or 2 °), and based on data obtained by each sampling, a transmission quality reference value at a corresponding horizontal rotation angle may be calculated. The transmission quality reference value can reflect the transmission quality of signals between the directional antenna and the communication opposite terminal facing downwards at present, the larger the transmission quality reference value is, the higher the transmission quality is, and on the contrary, the smaller the transmission quality reference value is, the lower the transmission quality is.
In an actual scenario, since the uplink and downlink transmission rates have a greater influence on the transmission quality and other auxiliary parameters have a relatively smaller influence on the transmission quality, the uplink and downlink transmission rates may be used as the main parameters and other auxiliary parameters may be used as the auxiliary parameters when calculating the transmission quality reference value. For example, in the solution of the embodiment of the present application, a transmission quality reference value may be calculated by using a weighted calculation method, and at this time, the weight of the uplink and downlink transmission rate may be set to be higher than the auxiliary parameter, so that a result more in line with an actual situation may be calculated, and accuracy of antenna orientation adjustment may be improved.
In some embodiments of the present application, the auxiliary parameter includes at least any one or more of a transmission power, a reception signal-to-noise ratio, a reception packet loss rate, a transmission packet loss rate, a reception bandwidth, and a transmission bandwidth. For example, in this embodiment, if the transmission power, the receiving signal-to-noise ratio, the receiving packet loss rate, the transmitting packet loss rate, the receiving bandwidth, and the transmitting bandwidth are used as auxiliary parameters, and the uplink and downlink transmission rates are combined, a more accurate transmission quality reference value can be calculated.
Wherein, the transmission quality reference value can be calculated by adopting the following method:
the transmission quality reference value a is the downlink transmission rate multiplied by 10+ the uplink transmission rate multiplied by 10-transmission power + the received signal to noise ratio-the received packet loss rate-the transmission packet loss rate + the received bandwidth + the transmission bandwidth. For example, when the horizontal rotation angle α is a certain horizontal rotation angle α, the downlink transmission rate is 100Mbps, the uplink transmission rate is 50Mbps, the transmission power is 20dBm, the received signal-to-noise ratio is 15dB, the received packet loss rate is 5%, and the transmission packet loss rate is 3%, then the corresponding transmission quality reference value a is 1487 — 100 × 10+50 × 10-20+ 15-5-3. During the horizontal rotation, the transmission quality reference values at different horizontal rotation angles may be calculated sequentially, for example, the transmission quality reference value a at the horizontal rotation angle β is 1523, the transmission quality reference value a at the horizontal rotation angle θ is 1577, and the transmission quality reference value a at the horizontal rotation angle δ is 1511.
Step S203, the wireless communication module determines a target horizontal rotation angle corresponding to the optimal transmission quality reference value according to the change trend of the transmission quality reference value based on the horizontal rotation angle.
After the wireless communication module obtains the transmission quality reference values corresponding to the horizontal rotation angles, the change trend of the transmission quality reference values along with the change of the horizontal rotation angles can be determined according to the change situation of the transmission quality reference values, and therefore the target horizontal rotation angle corresponding to the optimal transmission quality reference value can be determined according to the change trend.
In an actual scenario, the target horizontal rotation angle may be determined in the following manner: firstly, the wireless communication module acquires transmission quality reference values under different horizontal rotation angles, then determines the maximum value from the transmission quality reference values under different horizontal rotation angles as the optimal transmission quality reference value, and then determines the horizontal rotation angle corresponding to the optimal transmission quality reference value as the target horizontal rotation angle.
For example, the transmission quality reference values corresponding to the horizontal rotation angles α, β, θ, and δ sequentially acquired as described above have a tendency of increasing first and then decreasing, where the transmission quality reference value a is 1577, which is the maximum value at the horizontal rotation angle θ. Therefore, the transmission quality reference value can be determined to be the optimal transmission quality reference value, and the corresponding horizontal rotation angle theta can be determined to be the target horizontal rotation angle.
Step S204, the wireless communication module controls the motor to drive the rotating structure to the target horizontal rotation angle, so as to adjust the directional antenna to the optimal horizontal orientation. Taking the foregoing scenario as an example, when the wireless communication module controls the motor to drive the rotating structure to the target horizontal rotation angle θ, the current orientation of the directional antenna is the optimal horizontal orientation, that is, the directional antenna is in the state of highest transmission quality.
In some embodiments of the present application, in order to achieve better adjustment, the adjustment of the orientation may be performed in a vertical direction in addition to the adjustment of the orientation in a horizontal direction. That is, in another antenna control method for a wireless terminal device provided in this embodiment of the present application, after adjusting the directional antenna to the optimal horizontal orientation, the method further includes the steps shown in fig. 3:
step S301, the wireless communication module controls the motor to drive the rotating mechanism to rotate in a preset vertical direction, so that the directional antenna and the rotating mechanism synchronously rotate.
Step S302, the wireless communication module obtains the uplink and downlink transmission rate and the auxiliary parameter of the directional antenna in the vertical rotation process, and calculates the transmission quality reference value under the corresponding vertical rotation angle according to the uplink and downlink transmission rate and the auxiliary parameter.
Step S303, the wireless communication module determines a target vertical rotation angle corresponding to the optimal transmission quality reference value according to the variation trend of the transmission quality reference value based on the vertical rotation angle.
Step S304, the wireless communication module controls the motor to drive the rotating structure to the target vertical rotation angle, so as to adjust the directional antenna to the optimal vertical orientation.
In the process of adjusting the orientation in the vertical direction, the processing procedure of the wireless communication module is similar to that in the horizontal direction, for example, when the wireless communication module determines the target vertical rotation angle corresponding to the optimal transmission quality reference value according to the variation trend of the transmission quality reference value based on the vertical rotation angle, the similar method can also be adopted: that is, the wireless communication module first obtains the transmission quality reference values at different vertical rotation angles, then determines the maximum value from the transmission quality reference values at different vertical rotation angles as the optimal transmission quality reference value, and then determines the vertical rotation angle corresponding to the optimal transmission quality reference value as the target vertical rotation angle. Therefore, more accurate directional antenna orientation adjustment is achieved, and transmission quality between the wireless terminal device and the communication opposite terminal is better.
In an actual scenario, since the communication quality is also interfered by many other factors, such as climate changes of temperature, humidity, and other signal sources nearby, a preset time duration may be set, so that the method is repeatedly executed every preset time duration, for example, the preset time duration may be set to t seconds or s minutes according to the requirements of an actual application scenario, thereby ensuring that the transmission quality is maintained in an optimal state.

The power supply circuit 450 is used as a power supply module of the wireless terminal device, is connected to an external power supply through the power supply port 470, and supplies power to the wireless communication module 460 and the motors 421 to 422. The motors 421 and 422 are respectively a first motor for controlling the rotation in the horizontal direction and a second motor for controlling the rotation in the vertical direction, and drive the corresponding rotation mechanisms to rotate under the control of the wireless communication module. The horizontal rotation mechanism 430 and the vertical rotation mechanism 440 are driven by the motor to rotate in respective directions, so as to drive the directional antenna to rotate synchronously. The directional antennas 411-414 are used for transceiving wireless signals, and the wireless communication module is used for controlling the orientation of the directional antennas by adopting a corresponding antenna control method, so that the directional antennas can be in the optimal orientation.

6. the wireless communication module compares the variation trend of the above-mentioned parameters during the rotation of the antenna 1/2/3/4, with the uplink transmission rate being the most dominant and the other auxiliary parameters being the auxiliary, to obtain a determination value a, a being the downlink transmission rate × 10+ the uplink transmission rate × 10-the transmission power + the received signal-to-noise ratio-the received packet loss rate-the transmission packet loss rate + the received bandwidth + the transmission bandwidth. For example, when the downlink transmission rate is 100Mbps, the uplink transmission rate is 50Mbps, the transmission power is 20dBm, the received signal-to-noise ratio is 15dB, the reception packet loss rate is 5%, and the transmission packet loss rate is 3%, a is 100 × 10+50 × 10-20+15-5-3 or 1487, and a is larger, which indicates higher transmission quality.
