The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.
Furthermore, in the present application, directional terms "left", "right", etc. may be defined as including, but not limited to, a direction in which components in the drawings are schematically disposed, and it should be understood that these directional terms may be relative concepts, which are used for the description and clarity of relativity, and which may be correspondingly changed in accordance with the change in the direction in which the components in the drawings are disposed.
In the present application, unless explicitly specified and limited otherwise, the term "connected" is to be construed broadly, and for example, "connected" may be either fixedly connected, detachably connected, or integrally formed; can be directly connected or indirectly connected through an intermediate medium. Furthermore, the term "electrically connected" may be a way of achieving an electrical connection for signal transmission. The "electrical connection" may be direct electrical connection or may be indirect electrical connection via an intermediary.
First, the terms related to the present application will be briefly explained:
static medium pass equipment: a stationary communication device is understood to mean a communication connection established between satellite sites at a fixed location via a satellite access network; or establish a communication connection with the peer communication device.
Communication in motion equipment: the communication device is arranged on the application carrier, tracks the satellite position in real time in the process of following the movement of the application carrier, and performs signal forwarding by using the satellite as a relay station so as to establish communication connection with other communication devices. Such as vehicles, ships, tethered balloons, aircraft, airships, etc.
Currently, in some fields of scientific investigation, weather detection, emergency and the like, an air carrier-mounted communication device (i.e., as a communication-in-motion device) such as a tethered balloon or an airship is required, and/or a ground carrier-mounted communication device (i.e., as a communication-in-motion device) such as a vehicle is required to perform emergency communication. For example, when a natural disaster occurs in a certain place, an airship is quickly launched, and mobile communication in the entire disaster area can be restored in a short time by mounting a communication device on the airship.
In the above application scenario, in order to enhance the communication capability, a plurality of airships are usually launched to form an airship cluster for communication. For example, when the airships are communicated, if the distance is short, communication can be performed through wireless transmission and data transmission; if the distance is longer, communication must be performed through satellite transfer, at this time, in order to ensure the communication bandwidth for communication with the satellite, the receiving area of the satellite antenna in the communication device carried by the airship is designed to be large correspondingly, so that the size and weight of the whole satellite antenna are increased, which is not beneficial to the fields of scientific investigation, weather detection, emergency and the like. In addition, when communication is carried out through satellite transfer, great delay is generated, and the communication quality is affected.
Thus, a new communication device is needed to solve the satellite bandwidth traffic tariffs for communication without depending on satellite resources.
In view of the above, an embodiment of the present application provides a communication apparatus, which is applied to a first device, and an antenna feeder assembly in the first device is aligned with a second device in an initial pointing direction, so as to receive a signal from the second device through the antenna feeder assembly. The radio frequency processing component obtains a control voltage according to the signal and provides the control voltage to the servo control unit. Therefore, the servo control unit can adjust the pointing direction of the antenna feeder component according to the magnitude of the control voltage until the pointing direction corresponding to the target control voltage is determined to be the target pointing direction, so that the antenna feeder component is adjusted to the target pointing direction, and the second equipment is aligned by continuously adjusting the pointing direction, so that the control voltage is greater than or equal to the preset voltage, the purposes of establishing a communication link with optimal quality between the first equipment and the second equipment, and providing more efficient and reliable communication guarantee without depending on satellite resources are achieved.
The following describes the structure of the communication device according to the embodiment of the present application in detail with reference to fig. 1 to 5. Fig. 1 shows a schematic structural diagram of a communication device 3 according to an embodiment of the present application.
The communication means 3 are applied to a first device which is in communication connection with at least one second device, at least one of the first device and the second device being a communication-in-motion device.
For example, the first device and the second device are all communication-in-motion devices, and then the first device may be referred to as a first communication-in-motion device, and the second device may be referred to as a second communication-in-motion device. Alternatively, the first device is a communication-in-motion device and the second device is a communication-in-static device. Alternatively, the first device is a static communication device and the second device is a dynamic communication device. The "communication-in-motion device" means an airship-mounted communication device, a vehicle-mounted communication device, or the like, and the "first" and the "second" are used only for distinguishing objects.
Here, the second communication-in-motion device may be identical to or different from the first communication-in-motion device in structure, and the second communication-in-motion device may be identical to or different from the first communication-in-motion device in structure, which is not limited in any way by the embodiment of the present application.
As shown in fig. 1, the communication device 3 includes: the antenna feeder 100, the radio frequency processing 200, the servo control 300 and the adjustment 500.
The antenna feed assembly 100 is aligned with the second device in an initial pointing direction, and the antenna feed assembly 100 is configured to receive signals from the second device. Wherein the initial pointing direction is determined by first information comprising a pose and heading of the first device, a location of the second device.
It should be appreciated that the antenna feed assembly 100 includes an antenna face and a feed.
It should be understood that, since the first device and the second device on which the communication device 3 is mounted communicate with each other to directly form a communication link between the plurality of devices, and no communication connection with a satellite is required, and the communication bandwidth requirement is relatively low, the antenna size in the antenna feeder assembly 100 does not need to have a particularly large receiving area, so that the size, weight, and the like of the antenna feeder assembly 100 are relatively low, and the communication device 3 is relatively easy to be mounted on an air carrier or a ground carrier, and is convenient to use.
In addition, as no satellite is used as a relay station for signal forwarding, communication is only carried out among a plurality of devices, so that the time delay problem caused by signal forwarding of the satellite is eliminated, and the communication efficiency and the communication quality are better.
The rf processing unit 200 is connected to the antenna feeder unit 100 and the servo control unit 300, and the rf processing unit 200 is configured to provide a control voltage determined according to the received signal to the servo control unit 300.
The servo control unit 300 is further connected to the adjustment assembly 500, and if the control voltage is smaller than the preset voltage when the orientation of the antenna feeder assembly 100 is the initial orientation direction, the servo control unit 300 controls the adjustment assembly 500 to adjust the orientation direction of the antenna feeder assembly 100, and collects the control voltages corresponding to different orientation directions until the target control voltage is determined,
the preset voltage is used as a reference voltage for adjusting the pointing direction of the antenna feeder assembly 100 by the servo control unit 300, and the magnitude of the preset voltage may need to be set and adjusted, which is not limited in the embodiment of the present application.
It should be understood that, once the orientation direction of the antenna feeder 100 is adjusted, the quality of the signal received by the antenna feeder 100 will be affected, and the control voltage provided by the rf processing unit 200 to the servo control unit 300 will be changed accordingly, that is, the relationship between the orientation direction of the antenna feeder 100 and the control voltage provided by the rf processing unit 200 to the servo control unit 300 is one-to-one.
It should be appreciated that when the control voltage is greater than or equal to the preset voltage, the antenna feeder assembly 100 is indicated to be properly oriented to meet the communication requirement, and communication can be performed, so that the antenna feeder assembly 100 is locked, the first device is in communication line connection with the second device and is not changed, and the second device can start to send signals to the first device.
When the control voltage is smaller than the preset voltage, the pointing direction is poor, which may damage the communication quality, and therefore, the antenna feeder assembly 100 needs to be adjusted, and at this time, the servo control unit 300 may control the adjusting assembly 500 to adjust the pointing direction of the antenna feeder assembly 100, and stop until the control voltage is adjusted to be greater than or equal to the preset voltage.
It should be understood that the servo control unit 300 may control the adjustment assembly 500 to adjust the pointing direction of the antenna feeder assembly 100 to perform a small swing adjustment, and the swing amplitude may be set and changed as required, which is not limited in any way according to the embodiment of the present application.
It should be understood that the target control voltage may be the maximum control voltage among the plurality of control voltages corresponding to the collected different pointing directions, or may be a control voltage satisfying other conditions.
The adjustment assembly 500 is used to control the antenna feed assembly 100 to align the second device in the target pointing direction; the target pointing direction is the pointing direction corresponding to the target control voltage.
It should be understood that aligning the antenna feed assembly 100 with the target pointing direction for the second device means that the antenna feed assembly 100 in the first device is adjusted to the pointing direction that is optimal in terms of quality of communication with the second device. At this time, when the first device is aligned with the second device in the target pointing direction, the control voltage should be greater than or equal to the preset voltage.
Here, after the servo control unit 300 determines the target pointing direction, adjustment may be continued. The adjustment assembly 500 adjusts the antenna feeder assembly 100 to the target pointing direction, and then the adjustment assembly 500 adjusts the antenna feeder assembly 100 to continuously perform cone scan tracking within a small angle range, and the servo control unit 300 continuously determines whether the received control voltage always meets the requirement of being greater than or equal to the preset voltage. If this is not satisfied, a further small adjustment of the target pointing direction is required. This ensures reliable communication even in the case where the antenna feed assembly 100 is directed to a small deviation due to mechanical reasons or the like.
The embodiment of the application provides a communication device, which is applied to a first device, wherein an antenna feeder assembly of the first device is aligned with a second device in an initial pointing direction so as to receive a signal from the second device through the antenna feeder assembly. The radio frequency processing component obtains a control voltage according to the signal and provides the control voltage to the servo control unit. However, at least one of the first device and the second device is an on-the-fly device, so when the position of at least one of the two devices changes, the relative position between the two devices will change, based on this, since the control voltage is determined by the received signal, if the control voltage is smaller than the preset voltage, it indicates that the antenna feeder component is not aligned with the second device, therefore, the servo control unit can adjust the pointing direction of the antenna feeder component according to the magnitude of the control voltage until it determines that the pointing direction corresponding to the target control voltage is the target pointing direction, thereby adjusting the antenna feeder component to the target pointing direction, so as to align the second device by continuously adjusting the pointing direction, so that the control voltage is greater than or equal to the preset voltage, thereby realizing that the first device and the second device establish a communication link with optimal quality, providing more efficient and reliable communication guarantee, and achieving the purposes of not relying on satellite resources and providing more efficient and reliable communication guarantee.
Fig. 2 is a schematic structural diagram of another communication device according to an embodiment of the present application.
Optionally, as a possible implementation manner, as shown in fig. 2, the communication device further includes: a data acquisition component 400.
The data acquisition component 400 is connected to the servo control unit 300, and the data acquisition component 400 is configured to acquire first information and provide the first information to the servo control unit 300.
The servo control unit 300 is configured to determine an initial pointing direction of the antenna feeder assembly 100 according to the first information, and is configured to control the adjustment assembly 500 to adjust the pointing direction of the antenna feeder assembly 100 to the initial pointing direction.
