Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The embodiment of the disclosure provides a method for detecting a signal transmitting direction, by which the transmitting direction of a wireless signal can be accurately determined, and a foundation is laid for improving the wireless communication quality between communication devices. Fig. 1 is a flowchart of a method for detecting a signal transmission direction according to an embodiment of the present disclosure. As shown in fig. 1, the method is applied to a processor arranged in a communication device, and comprises the following steps:
step S11: controlling an antenna of the communication equipment to sequentially receive wireless signals in a plurality of radiation directions, wherein a plurality of radiation ranges corresponding to the plurality of radiation directions can be overlapped to cover a horizontal radiation range of 360 degrees;
step S12: performing interpolation processing on the signal intensity of the wireless signals respectively received by the plurality of radiation directions;
step S13: and determining the transmitting direction of the wireless signal according to the interpolation processing result.
In the embodiment of the present disclosure, the communication device may be any device capable of wireless communication, such as a drone, having an antenna.
In the embodiment of the present disclosure, the communication technologies used for wireless communication between communication devices include, but are not limited to: WIFI (a technology that allows an electronic device to connect to a wireless local area network), BT (Bluetooth), ZIGBEE (a short-range, low-power wireless communication technology), LTE (Long Term Evolution), and the like.
Regardless of the communication technology used for wireless communication between communication devices, the communication devices can receive wireless signals through antennas. Specifically, the processor controls an antenna of the communication device to sequentially receive wireless signals in a plurality of radiation directions. Each radiation direction in the plurality of radiation directions corresponds to a radiation range, and the plurality of radiation ranges corresponding to the plurality of radiation directions can be overlapped to cover a horizontal 360-degree radiation range. Illustratively, the radiation range of one directional antenna is: the elevation angle is 90 degrees and the horizontal direction angle is 60 degrees, and 6 directional antennas are needed in order to cover the horizontal radiation range of 360 degrees.
Each time the communication device receives a wireless signal in a radiation direction, the processor determines the signal strength of the wireless signal received in that radiation direction. Thus, after the communication device receives the wireless signals in the plurality of radiation directions, the processor determines the signal strengths of the wireless signals respectively received by the communication device in the plurality of radiation directions. The method for determining the signal strength includes, but is not limited to: RSSI (Received Signal Strength Indication), RSCP (Received Signal Code Power), RSRP (Reference Signal Receiving Power), correlation value, and the like.
Next, the processor performs interpolation processing on the signal strengths of the wireless signals received in the plurality of radiation directions, respectively. The interpolation processing method includes, but is not limited to, the following methods:
and performing interpolation processing according to the signal intensity of the wireless signals respectively received by the plurality of radiation directions, the angles of the plurality of radiation directions and the weights of the plurality of radiation directions to determine the target direction with the strongest signal intensity.
In the disclosed embodiments, each radiation direction has various parameters: the method comprises the steps of signal strength, a weight and an angle, wherein the weight is preset, and the angle is a clockwise angle relative to the positive direction of a Y axis on a horizontal plane. And performing interpolation processing according to the respective parameters of each radiation direction in the plurality of radiation directions, and further determining the target direction with the strongest signal intensity.
For example, taking the number of the plurality of radiation directions as 4 as an example, the weights thereof are respectively B1, B2, B3 and B4, the signal strengths are respectively R1, R2, R3 and R4, and the clockwise angles to the positive direction of the Y axis on the horizontal plane are respectively a1, a2, A3 and a4, then the angle (clockwise angle relative to the positive direction of the Y axis on the horizontal plane) ALPHA of the target direction with the strongest signal strength is determined as:
ctg(ALPHA)＝(B1*R1*COS(A1)+B2*R2*COS(A2)+B3*R3*COS(A3)+B4*R4*COS(A4))/(B1*R1*SIN(A1)+B2*R2*SIN(A2)+B3*R3*SIN(A3)+B4*R4*SIN(A4))。
similarly, taking the number of the plurality of radiation directions as n as An example, the weights of the radiation directions are B1, B2 and B3 … … Bn, the signal intensities are R1, R2 and R3 … … Rn, and the clockwise angles with the positive direction of the Y axis on the horizontal plane are a1, a2 and A3 … … An, respectively, then the angle (the clockwise angle with respect to the positive direction of the Y axis on the horizontal plane) ALPHA of the target direction with the strongest signal intensity is determined as:
ctg(ALPHA)＝(∑Bn*Rn*COS(An))/(∑Bn*Rn*SIN(An))。
finally, the processor determines the transmitting direction of the wireless signal according to the interpolation processing result. If the interpolation processing is performed only once, the result of the interpolation processing is the transmission direction of the wireless signal. If the interpolation processing is performed a plurality of times, the transmission direction of the wireless signal is determined by integrating the results of the interpolation processing a plurality of times.
By adopting the technical scheme, the signal intensity of the wireless signals received by the antenna of the communication equipment in a plurality of radiation directions is subjected to interpolation processing, and the transmission direction of the wireless signals is determined. On one hand, by means of interpolation processing, the radiation direction resolution is improved, and the accuracy of determining the transmitting direction of the wireless signal is enhanced. On the other hand, because a plurality of radiation ranges corresponding to a plurality of radiation directions can overlap and cover the radiation range of the horizontal 360 degrees, the radiation direction of the communication equipment for receiving the wireless signal is more comprehensive, the accuracy of determining the transmitting direction of the wireless signal is further improved, and a foundation is laid for improving the wireless communication quality between the communication equipment.
Optionally, the processor performs step S11 in a time division multiplexing manner. The step S11 is executed in a time division multiplexing manner according to the antenna arrangement situation of the drone, and is not limited to the first embodiment and the second embodiment described below.
The first embodiment is applicable to a case where the antenna of the communication device includes a plurality of directional antennas corresponding to a plurality of radiation directions, respectively. Fig. 2 is another flowchart of a method for detecting a signal transmission direction according to an embodiment of the present disclosure. As shown in fig. 2, step S11 includes:
step S111: and controlling the plurality of directional antennas to sequentially receive the wireless signals in the respective radiation directions in different time periods.
The second embodiment is applicable to the case where the antenna of the communication device is an omni-directional antenna. Fig. 3 is another flowchart of a method for detecting a signal transmission direction according to an embodiment of the present disclosure. As shown in fig. 3, step S11 includes:
step S1121: sequentially enabling a plurality of configurations of the omnidirectional antenna at different time periods, each configuration corresponding to one of the plurality of radiation directions;
step S1122: and controlling the omnidirectional antenna to sequentially receive the wireless signals in the radiation direction corresponding to the configuration in the enabling state.
First, a first embodiment will be explained.
In the case where the unmanned aerial vehicle includes N directional antennas, since respective radiation directions of the N directional antennas are different from each other, the processor divides a total time period required for determining a transmission direction of the wireless signal into a plurality of continuous time periods, each time period corresponding to one directional antenna, and in each time period, controls the directional antenna corresponding to the time period to receive the wireless signal in the radiation direction thereof.
Illustratively, the antenna of the communication device includes 6 directional antennas, and the processor divides the total time required to determine the transmission direction of the wireless signal into 1ms to 6ms, taking 1 millisecond (ms) as an example of one time unit. At 1ms, the processor controls the 1 st directional antenna to receive wireless signals in the radiation direction of the directional antenna; at 2ms, the processor controls the 2 nd directional antenna to receive the wireless signal in the radiation direction; and so on, until at the 6 th ms, the processor controls the 6 th directional antenna to receive the wireless signal in the radiation direction.
Next, a second embodiment will be explained.
In a case where the antenna of the communication device is an omnidirectional antenna, since the omnidirectional antenna has a plurality of configurations set in advance, each configuration corresponding to one radiation direction, and respective radiation directions of the plurality of configurations are different from each other, the processor divides a total time period required for determining the transmission direction of the wireless signal into a plurality of continuous time periods, each time period corresponding to one configuration. In each time period, the processor enables the configuration corresponding to the time period, and then controls the omnidirectional antenna to receive the wireless signal in the radiation direction corresponding to the configuration in the enabled state.
Illustratively, the antennas of the communication device include 1 omni-directional antenna having 6 configurations set in advance, and the processor divides the total time period required to determine the transmission direction of the wireless signal into 1ms to 6 ms. In the 1 st ms, enabling the 1 st configuration by the processor, and then controlling the omnidirectional antenna to receive the wireless signal in the radiation direction corresponding to the 1 st configuration; enabling the 2 nd configuration by the processor in the 2 nd ms, and then controlling the omnidirectional antenna to receive the wireless signal in the radiation direction corresponding to the 2 nd configuration; and so on, until the 6 th configuration is enabled by the processor at the 6 th ms, and then the omnidirectional antenna is controlled to receive the wireless signal in the radiation direction corresponding to the 6 th configuration.
Alternatively, the interpolation process in step S12 may be performed a plurality of times in order to improve accuracy. Accordingly, step S12 includes:
after the interpolation processing is carried out for one time, the target direction with the strongest signal intensity is determined;
when the target direction determined this time does not coincide with any of the plurality of radiation directions, adjusting one of the plurality of radiation directions to coincide with the target direction determined this time, and repeatedly performing the steps of sequentially receiving wireless signals in the plurality of radiation directions by an antenna of the control communication device, and performing interpolation processing on the signal strengths of the wireless signals respectively received in the plurality of radiation directions;
after interpolation processing is carried out each time, whether the target direction with the strongest signal intensity is coincided with any radiation direction in the plurality of radiation directions or not is determined;
and when the determined direction with the strongest signal strength is coincident with any one of the plurality of radiation directions, determining the coincident antenna radiation direction as the transmission direction of the wireless signal.
No matter whether the antenna of the communication device includes a plurality of directional antennas corresponding to the plurality of radiation directions, respectively, or whether the antenna of the communication device is an omnidirectional antenna and has a plurality of configurations, the number of radiation directions is always limited, and a target direction with the strongest signal strength obtained after one interpolation process may not coincide with any of the plurality of radiation directions.
For example, taking the number of the plurality of radiation directions as 4 as an example, the clockwise angles of the radiation directions with the positive direction of the Y axis on the horizontal plane are a1, a2, A3 and a4 respectively, after one interpolation process, the angle (clockwise angle with respect to the positive direction of the Y axis on the horizontal plane) ALPHA of the target direction with the strongest signal intensity is determined as a5, and the size of a5 is between a1 and a 2.
In order to improve the accuracy, if the target direction with the strongest signal intensity obtained after the interpolation processing is not overlapped with any radiation direction in the plurality of radiation directions, one radiation direction in the plurality of radiation directions is adjusted to be overlapped with the target direction determined at this time. One embodiment is: rotating the plurality of radiation directions until one radiation direction is superposed with the target direction determined at this time; another embodiment is: only one of the plurality of radiation directions is rotated until the radiation direction coincides with the target direction determined this time.
After adjusting one of the plurality of radiation directions to coincide with the target direction determined this time, the processor controls the antenna of the communication device to sequentially receive wireless signals in the plurality of radiation directions, and performs interpolation processing again on the signal strengths of the wireless signals respectively received by the plurality of radiation directions, so as to verify whether the target direction determined according to the last interpolation processing is indeed the target direction with the strongest signal strength according to the result of the interpolation processing again, and if the result of the interpolation processing again is the radiation direction after coincidence, it indicates that the target direction determined by the last interpolation processing is indeed the target direction with the strongest signal strength, that is, the target direction determined by the last interpolation processing is accurate; if the result of the re-interpolation process is not the overlapped radiation direction, it indicates that the target direction determined by the previous interpolation process is not accurate, and steps S11-S13 need to be re-executed.
Illustratively, continuing with the example where the number of the plurality of radiation directions is 4, after performing the interpolation process once, the angle (clockwise angle with respect to the positive Y-axis direction on the horizontal plane) ALPHA of the target direction with the strongest signal strength is determined to be a5, and the size of a5 is between a1 and a2, in which case, for the purpose of improving accuracy, the 4 radiation directions are rotated as a whole until the clockwise angle between the 2 nd radiation direction and the positive Y-axis direction on the horizontal plane is changed from a2 to a 5. Then, the processor controls the antenna of the communication device to sequentially receive the wireless signals in the 4 radiation directions, and performs interpolation processing again on the signal strengths of the wireless signals respectively received in the 4 radiation directions, so as to verify whether the a5 is indeed the target direction with the strongest signal strength according to the result of the interpolation processing again, and if the angle (clockwise angle relative to the positive direction of the Y axis on the horizontal plane) ALPHA of the target direction with the strongest signal strength is determined to be a5 after the interpolation processing again, the target direction determined by the last interpolation processing is indeed the target direction with the strongest signal strength, that is, a5 is indeed the target direction with the strongest signal strength; otherwise, steps S11-S13 are re-executed.
