Fig. 2 is a flowchart illustrating a multi-antenna data transmission method according to an embodiment of the present invention. As shown in fig. 2, the method includes the following steps S110 to S150.
S110, acquiring data to be transmitted from a transmitting end.
In this embodiment, the data to be transmitted refers to data that needs to be transmitted to the receiving end from the transmitting end, where the data to be transmitted includes image information, and the image information may be directly imported by the transmitting end or captured by a camera of the transmitting end.
And S120, determining the sequence of data transmission of a plurality of antennas in the router according to the quantity of the data to be transmitted.
In this embodiment, the sequence of data transmission by the antennas refers to the sequence of data transmission by the antennas in the router, and is accurate to the radio frequency direction of the antennas.
In this embodiment, the router is provided with a plurality of antennas, and in order to improve the transmission rate of the router, the plurality of antennas simultaneously perform data transmission, so that the router can transmit massive data.

When the router leaves factory, a total throughput test is carried out on each antenna to determine the maximum throughput of each antenna, the current data volume which can be received and transmitted by each antenna can be tested by the server, and the current data volume which can be received and transmitted by each antenna is subtracted from the total throughput when leaving factory, so that the current data volume which can be received and transmitted by each antenna, namely the current actual throughput of each antenna is determined.

The optimal combination of throughput value and radio frequency direction can be achieved through comparison of radar maps, and the limiting condition is the angle of the receiving end relative to the router.
And S123, acquiring the time for the receiving end to feed back the radio frequency signals after receiving the radio frequency signals of each antenna in different radio frequency directions, so as to obtain the feedback time of each antenna in different radio frequency directions.
In this embodiment, since the amount of data to be transmitted may be small or large, it is necessary to determine whether to prioritize throughput or transmission rate according to actual conditions.
The feedback time in the different radio frequency directions of each antenna refers to the time for the receiving end to receive the radio frequency signals of each antenna in the different radio frequency directions and then feed back the radio frequency signals, that is, the feedback time for the receiving end to send out the radio frequency signals in the different radio frequency directions for each antenna.

TABLE 1 table of transmission duration arrangement result integration
As can be seen from table 1: when the antenna 1 is in the radio frequency direction of 45 degrees, the transmission time length is the shortest in all the antennas; the transmission duration corresponding to the antennas in different radio frequency directions is sequenced from short to long in sequence as follows: 45 for antenna 1 < 120 for antenna 3 < 90 for antenna 2.
S1243, determining radio frequency directions corresponding to the sequencing of the radiation field intensity of the antenna from strong to weak from the radar map to obtain a radio frequency direction sequencing result.
In this embodiment, the radio frequency direction sorting result refers to the radio frequency direction corresponding to the sorted antenna radiation field strength of each antenna from strong to weak determined in the radar chart, and the radio frequency direction sorting result is also similar to the transmission duration sorting result, and each radio frequency direction sorting result of the plurality of antennas can be integrated in one table for comparison, so as to determine the radio frequency direction of each antenna obtained by sorting the antenna radiation field strengths in the plurality of antennas, as shown in table 2.

In this embodiment, when the number of data to be transmitted exceeds a preset condition, for example, the number is 3 thousand, the throughput of the antenna needs to be taken as a priority content, at this time, the optimal radio frequency direction of each antenna for the receiving end needs to be determined from the radio frequency direction sorting result, and as shown in table 2, 120 ° of the antenna 1, 120 ° of the antenna 2, and 90 ° of the antenna 3 are selected as the optimal radio frequency directions; when the amount of data to be transmitted does not exceed the preset condition, the transmission rate of the antenna needs to be taken as a priority content, at this time, the optimal radio frequency direction of each antenna to the receiving end needs to be determined from the transmission duration arrangement result, and as shown in table 2, 45 ° of the antenna 1, 120 ° of the antenna 3, and 90 ° of the antenna 2 are selected as the optimal radio frequency directions.
In other embodiments, in the step S123, a weight value may be set for the transmission duration, a weight value may be set for the antenna radiation field, a total value of each antenna in different radio frequency directions is determined in a weighted summation manner, and the total values are sorted in a descending order to obtain a sorting result; and then, establishing a comparison table according to the first total value in each sequencing result and the corresponding radio frequency direction, thereby determining the optimal radio frequency direction of each antenna in the plurality of antennas for the receiving end and further determining the sequence of the plurality of antennas for transmitting data.
For example, the first total bit value of the antenna 1 is 34, and the corresponding radio frequency direction is 45 °; the first total value of the antenna 2 is 50, and the corresponding radio frequency direction is 120 degrees; the first total value of the antenna 3 is 20, and the corresponding radio frequency direction is 90 degrees; then the optimal rf direction for the multiple antennas to the receiving end should be: the sequential transmission of data can be done according to this order, 120 ° for antenna 2, 45 ° for antenna 1, and 90 ° for antenna 3.
When the transmission rate and the throughput are measured, the division is related to the fine degree of the division in the radio frequency direction, and the finer the division is, the better the transmission rate and the throughput are measured.
