Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The embodiment of the application provides an antenna system, and the antenna system can be applied to the application scenario shown in fig. 1. The application scene shown in fig. 1 is an application scene of an intelligent security camera, and is mainly used for monitoring security of a city. Besides security and protection scenes, the embodiment of the invention is also suitable for other scenes needing to use the wireless communication antenna to communicate with the signal source.
In the application scene shown in fig. 1, N cameras are included, and the cameras are in sequential communication connection, for example, the camera 1 is in communication connection with the camera 2, the camera 2 is in communication connection with the camera 3, and so on, until the camera N-1 is in communication connection with the camera N, and the camera N is in communication connection with the security control center.
Specifically, an antenna system may be provided in each camera, so as to realize transmission of video signals between the cameras based on the antenna systems. The following will be exemplarily described taking the camera 1 and the camera 2 as an example:
the camera 1 and the camera 2 are both provided with an antenna system, and the antenna system of the camera 1 transmits the video signal acquired by the camera to the antenna system of the camera 2.
Of course, the antenna system of the embodiment of the present application may also be applied to the application scenario shown in fig. 2. The application scenario shown in fig. 2 is an application scenario of automatic driving, and is mainly used for ensuring safe driving of a vehicle.
In the application scenario shown in fig. 2, a Road Side Unit (RSU) is provided on at least one side of the road, and the vehicle travels on the road.
The road side unit is provided with an antenna system so as to collect relevant information of vehicles running on a road, such as position information and speed information sent by the vehicles; an antenna system is also provided on the vehicle so as to transmit position information, speed information, and the like to the roadside unit through the antenna system.
That is to say that the interaction between the road side unit and the vehicle can be realized by means of a respective antenna system.
It should be noted that the above examples are only used for illustrating possible application scenarios of the antenna system, and are not to be understood as a limitation of the application scenarios of the antenna system.

However, if the direction, angle, etc. of the antenna system are adjusted manually, human resources are easily wasted, and the adjustment process is easily affected by human factors, which results in a problem of low accuracy of adjustment; if the direction, the angle, etc. of the antenna system are adjusted by the way of rotating the motor, the cost of the motor is relatively high, so that the problem of cost waste is easily caused, and the problem of low adjustment precision may be caused by the parameters of the motor itself and the parameters of friction of the rotating shaft, etc.
The inventors of the present application, after having made creative efforts, have conceived the inventive concept of the present application: an antenna system is designed, which comprises a plurality of directional antennas, and the orientation of each directional antenna is different, so that a certain directional antenna for receiving the signal sent by the signal source is selected through the performance of signal transmission between each directional antenna and the signal source.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
According to an aspect of an embodiment of the present application, an embodiment of the present application provides an antenna system.
Referring to fig. 3, fig. 3 is a schematic diagram of an antenna system according to an embodiment of the present application.
As shown in fig. 3, the antenna system includes:
a plurality of directional antennas for receiving the detection signal from the signal source, wherein different directional antennas are oriented differently.
And a processor, configured to select a directional antenna as a receiving antenna from the multiple directional antennas according to signal strengths (hereinafter, referred to as signal strengths) of the detection signals received by the multiple directional antennas.
Wherein, the receiving antenna is used for receiving the service data signal from the signal source after the processor completes the selection.
In particular, fig. 3 exemplarily shows an antenna system including three directional antennas, and the three directional antennas are oriented differently, and each of the three directional antennas can receive a detection signal from a signal source.
The directional antenna (directional antenna) is used for representing an antenna which transmits and receives signals in a specific direction and is particularly strong, and transmits and receives signals in other directions are zero or extremely small; the signal source is used for representing equipment for signal transmission with the antenna system; the detection signals are used for representing data for detecting the signal transmission performance between each directional antenna and the signal source, and the signal transmission performance comprises signal strength.
For example, in an application scenario as shown in fig. 1, if the camera 1 transmits the captured video signal to the camera 2, the signal source may be the camera 1, and specifically may be an antenna disposed on the camera 1.
For another example, in an application scenario as shown in fig. 2, if the road side unit sends the collected road condition information to the vehicle, the signal source may be the road side unit, and specifically may be an antenna disposed in the road side unit.
It should be noted that fig. 3 shows three directional antennas for exemplary purposes only, and is not to be construed as the number of directional antennas included in the antenna system.
In some embodiments, the number of directional antennas may be two, and in other embodiments, the number of directional antennas may be greater than three, such as 4, 5, or 6. The number of directional antennas may be selected based on the application requirements of the antenna system.
For example, if the antenna system can receive signals from two signal sources, the number of directional antennas in the antenna system can be set to two, and the orientation of one directional antenna matches the direction of one signal source.
For another example, if the antenna system can receive signals from six signal sources, the number of directional antennas in the antenna system can be set to six, and the orientation of one directional antenna is matched with the direction of one signal source.
For another example, if the antenna system can receive signals from six signal sources, the number of directional antennas in the antenna system can be set to three, and the orientation of one directional antenna matches the directions of two signal sources.
Specifically, when the orientation of one directional antenna is matched with the direction of one signal source, the orientation of the directional antenna is the direction opposite to the orientation of the signal source.
For example, when the signal source is oriented in a north-bound direction, the directional antenna is oriented in a south-bound direction.
Specifically, when the orientation of one directional antenna is matched with the directions of two signal sources, then the orientation of the directional antenna is a direction directly opposite to the average orientation of the orientations of the two signal sources.
For example, if one signal source is oriented in the north direction and the other signal source is oriented in the west direction, the directional antenna is oriented in the north-west direction.
In some embodiments, when there are multiple signal sources and the coverage direction of each signal source is each direction, that is, the coverage range of each signal source is 360 degrees, the number of directional antennas may be set to six, specifically referring to fig. 4, and the gain lobe width of each directional antenna may cover a range of 60 degrees, the coverage ranges of the six directional antennas may reach 360 degrees, and the six directional antennas may respectively receive the detection signal from the signal source through different orientations.
In some embodiments, the plurality of directional antennas may be enclosed into a column (e.g., cylinder, prism). An increased number of directional antennas may reduce signal shadowing, but may increase the cost of the antenna system. When the number of the directional antennas is 6, the 6 antennas surround to form a column shape, and the effect of signal blind areas can be basically avoided under the condition of low cost, especially for WiFi signals (such as 2.4GHz WiFi signals and 5GHz WiFi signals).
Wherein, a plane perpendicular to the axis of the column is taken as a cross section, and the cross section is circular or prismatic.
For example, when the number of directional antennas is six, the six directional antennas are enclosed into a column shape. And specifically six directional antennas may be enclosed by connectors including, but not limited to, snaps, clips, and ferrules.
It should be noted that, the signal source sends the same detection signal to six directional antennas with different orientations, and the signal strength of each directional antenna may be different due to the problems of the orientation, the angle, and the like between the signal source and each directional antenna.
In this embodiment, the processor may collect signal strength of each directional antenna, and select one or more directional antennas from six directional antennas as a receiving antenna according to the signal strength, so that the receiving antenna receives a traffic data signal from a signal source.
The embodiments of the present application will now be explained with reference to fig. 2 and 4 as examples:
as shown in fig. 4, the antenna system includes six directional antennas, which are a directional antenna a, a directional antenna B, a directional antenna C, a directional antenna D, a directional antenna E, and a directional antenna F, and is disposed on any one of the vehicles shown in fig. 2.
The processor of the antenna system selects directional antenna a from the six directional antennas as the directional antenna of the receiving antenna according to the signal strength of the detection signal received by the six directional antennas from the road side unit (i.e. the signal source), i.e. the traffic data signal is subsequently received by directional antenna a from the road side unit.
There are at least two ways for the processor to select the receive antenna, one of which is: the processor may select, from the plurality of directional antennas, a directional antenna having a signal strength greater than a threshold as a receive antenna; the other is as follows: the processor may select the directional antenna with the strongest signal strength from the plurality of directional antennas as the receiving antenna.
A first way of selecting a receive antenna for a processor is described as follows:
the processor may determine the signal strength of each directional antenna in turn, compare the signal strength of the directional antenna to a threshold, and select the directional antenna with the signal strength greater than the threshold as the receiving antenna.
Wherein the threshold may be determined based on requirements, experience, and experimentation.
For example, based on the above example, the processor may sequentially determine the signal strength of directional antenna a, directional antenna B, directional antenna C, directional antenna D, directional antenna E, and directional antenna F, compare the signal strength of directional antenna a to a threshold when the signal strength of directional antenna a is determined, and determine directional antenna a as a receive antenna if the signal strength of directional antenna a is greater than the threshold. In the embodiment of the application, the signal strength of other directional antennas does not need to be determined, and the signal strength of other directional antennas is compared with the threshold value, so that the computing resource is saved and the efficiency is improved.
A second way of selecting a receive antenna for the processor is described as follows:
and comparing the signal strength of each directional antenna, and selecting the directional antenna with the maximum signal strength as a receiving antenna.
For example, based on the above example, the processor may determine the signal strengths of directional antenna a, directional antenna B, directional antenna C, directional antenna D, directional antenna E, and directional antenna F, respectively, and compare the six signal strengths, and select directional antenna a as the receiving antenna if the signal strength of directional antenna a is greater than the signal strength of any one of the other five directional antennas, that is, the signal strength of directional antenna a is the largest of the six signal strengths. In the embodiment of the application, the directional antenna with the strongest signal strength is selected as the receiving antenna, so that the technical effect of reliability of subsequent service data signal transmission can be ensured.
Based on the above analysis, in the embodiment of the present application, an antenna system is provided, where the antenna system includes multiple directional antennas, and each directional antenna has a different orientation, and one or more directional antennas are selected from the multiple directional antennas as receiving antennas according to the signal strength of each directional antenna by using a processor, so that the receiving antennas receive service data signals from a signal source, on one hand, the problems of manpower resource waste and low accuracy caused by manually adjusting the direction, angle, and the like of the antenna system in the related art can be avoided, thereby achieving the technical effects of saving labor cost and improving accuracy; on the other hand, the problems of low cost waste and low accuracy caused by adjusting the direction, the angle and the like of the antenna system through the motor in the related technology can be solved, so that the technical effects of saving the motor cost and improving the accuracy are realized; and the receiving antenna is selected through the signal strength, which is equivalent to selecting the receiving antenna by combining the signal transmission performance between the antenna system and the signal source, so that the technical effects of improving the transmission performance and the efficiency can be realized.
In some embodiments, each directional antenna may support multiple frequency bands, such as a 2.4GHz band and a 5GHz band, among others.
In some embodiments, the antenna system may act as a receive antenna while acting as a transmit antenna, such as an antenna system with a relay function. The processor may obtain the service data signal from the receiving antenna, may determine a frequency band of the receiving antenna for receiving the service data signal sent by the signal source, and selects a directional antenna with a frequency band different from that of the receiving antenna from other directional antennas as the sending antenna. And transmitting the service data signal to a transmitting antenna so as to transmit the service data signal to the outside by the transmitting antenna.
Based on the above example, if the processor selects the directional antenna a as the transmitting antenna, the processor may determine a frequency band in which the directional antenna a receives the service data signal, and if the determined frequency band is 2.4GHz, the processor may respectively obtain frequency bands of the directional antenna B, the directional antenna C, the directional antenna D, the directional antenna E, and the directional antenna F, and if the frequency band of the directional antenna B among the five directional antennas is 5GHz, the processor may select the directional antenna B as the transmitting antenna, and transmit the service data signal obtained from the directional antenna a to the directional antenna B, so that the directional antenna B externally transmits the service data signal; if the frequency band of the multiple directional antennas in the five directional antennas is 5GHz, the processor may randomly select one directional antenna from the multiple directional antennas in the 5GHz frequency band as a transmitting antenna.
For example, in the application scenario shown in fig. 1, if the frequency band of the transmitting antenna of the camera 1 is 2.4GHz, the frequency band of the receiving antenna of the camera 2 is 5GHz, and the frequency band of the transmitting antenna of the camera 2 is 2.4GHz, and so on, which is not described herein again.
In the embodiment of the application, by selecting the directional antennas with different frequency bands as the receiving antenna and the transmitting antenna, the problem of signal interference between the receiving antenna and the transmitting antenna due to the same frequency band can be avoided, so that the technical effect of improving the reliability and effectiveness of service data signal transmission is realized.
In some embodiments, each directional antenna supports multiple frequency bands, such as a 2.4GHz band and a 5GHz band. And, it is understood that any frequency band includes a plurality of channels, such as a 2.4GHz band including 14 channels and a 5GHz band including about two hundred channels.
The processor can acquire the service data signal from the receiving antenna, determine the frequency band and the channel of the service data signal sent by the signal source received by the receiving antenna, select the directional antenna with the same frequency band and different channel as the receiving antenna from other directional antennas, and send the service data signal to the sending antenna, so that the sending antenna can send the service data signal to the outside.
Based on the above example, if the processor selects the directional antenna a as the transmitting antenna, the processor may determine a frequency band and a channel in which the directional antenna a receives the service data signal, and if the determined frequency band is 2.4GHz and the channel is the first channel, the processor may respectively obtain the frequency bands and the channels of the directional antenna B, the directional antenna C, the directional antenna D, the directional antenna E, and the directional antenna F, and if the frequency band of the directional antenna B among the five directional antennas is 2.4GHz and the channel of the directional antenna is the third channel, the processor may select the directional antenna B as the transmitting antenna, and transmit the service data signal obtained from the directional antenna a to the directional antenna B, so that the directional antenna B externally transmits the service data signal.
For example, in the application scenario shown in fig. 1, if the transmitting antenna of the camera 1 is in the 2.4GH frequency band and the channel of the transmitting antenna is the first channel, when the receiving antenna of the camera 2 is in the 2.4GHz frequency band, the channel of the receiving antenna of the camera 2 is selected as a channel other than the first channel, such as the second channel, and when the transmitting antenna of the camera 2 is in the 2.4GHz frequency band, the channel of the transmitting antenna of the camera 2 is selected as a channel other than the second channel, such as the third channel, and so on, which is not described herein again.
In the embodiment of the application, by selecting the directional antenna with the same frequency band and different channels as the receiving antenna as the transmitting antenna, the signal interference between the receiving antenna and the transmitting antenna caused by the same channels can be reduced, thereby realizing the technical effect of improving the reliability and effectiveness of service data signal transmission.
In some embodiments, each directional antenna may support multiple polarizations, such as horizontal, vertical, and angular polarizations.
And the processor can acquire the service data signal from the receiving antenna, determine the polarization mode of the receiving antenna, select a directional antenna with a polarization mode different from that of the receiving antenna from other directional antennas as a transmitting antenna, and transmit the service data signal to the transmitting antenna so as to transmit the service data signal to the outside by the transmitting antenna.
The polarization mode is used for representing the electric field intensity direction formed when the directional antenna transmits or receives the service data signal. When the electric field intensity direction is vertical to the ground, the method can be called a vertical polarization mode; when the electric field intensity direction is parallel to the ground, the method can be called a horizontal polarization mode; when the direction of the electric field strength forms a certain angle with the ground, the polarization mode can be called as an angular polarization mode, such as a positive 45-degree polarization mode and a negative 45-degree polarization mode.
Based on the above example, if the processor selects the directional antenna a as the transmitting antenna, the processor may determine a polarization manner in which the directional antenna a receives the service data signal, and if the determined polarization manner is a horizontal polarization manner, the processor may respectively obtain polarization manners of the directional antenna B, the directional antenna C, the directional antenna D, the directional antenna E, and the directional antenna F, and if only the polarization manner of the directional antenna B among the five directional antennas is a vertical polarization manner, the processor may select the directional antenna B as the transmitting antenna, and transmit the service data signal obtained from the directional antenna a to the directional antenna B, so that the directional antenna B externally transmits the service data signal; if a plurality of the five directional antennas are in a vertical polarization mode, the processor may randomly select one directional antenna from the plurality of directional antennas in the vertical polarization mode as the transmitting antenna.
In the embodiment of the application, by selecting the directional antennas with different polarization modes as the receiving antenna and the sending antenna, the problem of signal interference between the receiving antenna and the sending antenna due to the same polarization mode can be avoided, so that the technical effect of improving the reliability and effectiveness of service data signal transmission is realized.
In some embodiments, the processor and each directional antenna may be connected by a switch, wherein the processor is connected to one directional antenna by one switch.
