[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the existing technology, the ground-to-air communication of low-altitude aircraft only uses a certain communication technology, which has the risk of single point failure. When encountering sudden factors such as equipment failure, wireless resource interference, and obstacle obstruction, it will lead to communication termination. Therefore, the existing ground-to-air communication network of low-altitude aircraft is unreliable.

[0023] In order to solve the defect of unreliable ground-to-air communication network of low-altitude aircraft in the prior art, the present invention provides a redundant networking method, system, device and equipment for air-to-ground communication of low-altitude aircraft, so as to improve the reliability of the ground-to-air communication network of low-altitude aircraft.

[0024] Combine the following Figure 1-3 The present invention describes the low-altitude aircraft air-to-ground communication redundant networking method, such as Figure 1 As shown, the present invention provides a low-altitude aircraft air-to-ground communication redundant networking method, comprising the steps of: S110, establishing a first communication tunnel with a first airborne communication terminal of the low-altitude aircraft, and establishing a second communication tunnel with a second airborne communication terminal of the low-altitude aircraft, wherein the first airborne communication terminal and the second airborne communication terminal correspond to different communication technologies respectively; S120. When the first communication tunnel operates normally, air-to-ground data stream transmission is performed between the aircraft control platform and the low-altitude aircraft through the first communication tunnel; S130. When a failure occurs in the first communication tunnel, switch to the second communication tunnel to perform air-to-ground data stream transmission between the aircraft control platform and the low-altitude aircraft.

[0025] The method provided by the present invention sets a first airborne communication terminal and a second airborne communication terminal corresponding to two different communication technologies on a low-altitude aircraft, establishes a first communication tunnel and a second communication tunnel with the first airborne communication terminal and the second airborne communication terminal respectively, and when the first communication tunnel operates normally, performs air-to-ground data stream transmission between an aircraft control platform and the low-altitude aircraft through the first communication tunnel, and when a fault occurs in the first communication tunnel, switches to the second communication tunnel for air-to-ground data stream transmission between the aircraft control platform and the low-altitude aircraft, thereby realizing a redundant design of air-to-ground communication and improving the reliability of the air-to-ground communication network.

[0026] The method provided by the present invention can be executed by a switch, which is referred to as the first switch in the following text for the convenience of description. In the method provided by the present invention, two wireless airborne communication terminals are set on the low-altitude aircraft: a first airborne communication terminal and a second airborne communication terminal, which correspond to different communication technologies. The first airborne communication terminal and the second airborne communication terminal can respectively establish communication tunnels with the switch, such as a GRE communication tunnel. Figure 2 As shown, after being powered on, the first airborne communication terminal and the second airborne communication terminal set on the low-altitude aircraft normally access the network through the air interface, and establish a tunnel connection with the first switch through the base station and the core network.

[0027] If we simply use physical isolation of the two communication protocols to conduct end-to-end dual-link simultaneous communication, the number of airborne and ground equipment will double, the cost will increase dramatically, and there will be two risks: (1) If the network design is unreasonable, it is easy to cause a network storm. Since the airborne flight control system needs to access two communication devices at the same time, the ground flight control platform also needs to access the ground equipment of the two networks at the same time. If the network does not have a reasonable network isolation design, it will cause a network storm among the airborne equipment, the two wireless communication networks and the ground flight control platform; (2) Using two different communication technologies to transmit data simultaneously will double the sending and receiving of flight control data, doubling the system load. Doubling the downlink multimedia data will result in double traffic and duplication. The ground end needs to integrate and de-duplicate the data, which will also double the operating costs.

[0028] After the first switch establishes communication tunnels with the first airborne communication terminal and the second airborne communication terminal respectively, one communication tunnel is set as the main communication tunnel and the other communication tunnel is set as the backup communication tunnel. For example, according to the GRE master-slave protocol, the first communication tunnel is enabled as the main communication tunnel and the second communication tunnel is enabled as the backup communication tunnel.

[0029] When the first communication tunnel is operating normally, the first communication tunnel is used preferentially to transmit the air-to-ground data stream between the aircraft control platform and the low-altitude aircraft. At this time, the second communication tunnel is disconnected, no data transmission is performed, and no doubled traffic is generated. The aircraft control platform is used to receive and process data sent by the low-altitude aircraft, as well as to send control instructions to the low-altitude aircraft. The data stream between the aircraft control platform and the low-altitude aircraft is called the air-to-ground data stream. When a failure occurs in the first communication tunnel, such as equipment failure, wireless resource interference, obstacle obstruction, and other sudden factors leading to communication termination, the first switch switches to the backup communication tunnel, namely the second communication tunnel, to transmit the air-to-ground data stream. The first switch can automatically detect and switch to the backup communication tunnel, and the business system does not need to intervene, and is completely unaware of the business.

[0030] The method provided by the present invention designs a high-reliability master-slave redundancy solution by means of an air interface communication tunnel + a data center switch communication tunnel master-slave mode. Usually, only one master tunnel is used to send and receive data, and the other is used as a backup. When the master tunnel fails, the switch automatically switches to the backup tunnel, avoiding the doubling of traffic caused by sending and receiving data on both sides at the same time. The redundancy solution requires the cooperation of the airborne terminal and the first switch, both of which support the GRE tunnel function. The first switch enables the GRE master-slave protocol and is responsible for the detection and switching of the master-slave tunnel.

[0031] Further, in a possible implementation, the frequency of the first communication tunnel failure within a preset period can be counted. If the frequency is higher than the preset frequency, the priority of the first communication tunnel and the second communication tunnel can be switched. The communication tunnel with a high priority is the main communication tunnel, and the low priority is the backup communication tunnel. That is to say, when the communication tunnel with a high priority is operating normally, only the communication tunnel with a high priority is used to transmit the air-ground data stream. Only when the communication tunnel with a high priority fails, the communication tunnel with a low priority is used to transmit the air-ground data stream. Although the first communication tunnel is the main communication tunnel after the communication tunnel is established, it may be found in subsequent use that the frequency of failure of the first communication tunnel is high, which may lead to frequent switching of the communication tunnel. Although it will not affect the business, frequent switching may cause instability of communication. In a possible implementation of the method provided by the present invention, the frequency of failure of the main communication tunnel is counted every preset period. If the frequency of failure is too high, the current main communication tunnel is changed to the backup communication tunnel, and the backup communication tunnel is changed to the main communication tunnel. In the process of air-ground communication, the main and backup communication tunnels are modified dynamically in real time according to the actual operation situation, which can improve the stability of air-ground communication.

[0032] Furthermore, in the method provided by the present invention, a second switch is also provided, and the second switch is a switch of the flight control platform, which is connected to the flight control platform in communication, and the second switch is a data center switch. That is to say, in one embodiment of the method provided by the present invention, a data transfer point is set: the first switch. The first switch is not directly connected to the flight control platform, but is first connected to the flight control platform via the second switch. The air-to-ground data stream transmission between the aircraft control platform and the low-altitude aircraft includes: The air-to-ground data stream is transmitted via the aggregation port to the second switch, and the second switch is connected to the aircraft control platform.

[0033] The first switch is normally connected to the two communication technology core network devices through network cables or optical fibers, and the air-to-ground data streams of the two communication technologies are connected to the aircraft control platform switch, namely the second switch, through the link aggregation port.

[0034] Furthermore, the aggregation port includes a first aggregation port and a second aggregation port, the first aggregation port corresponds to the first communication tunnel, and the second aggregation port corresponds to the second communication tunnel. By setting two aggregation ports, when a certain link of the aggregation fails, the link aggregation automatically interrupts the aggregation port and switches the service to another aggregation port, and the transmission of the air-ground data flow is not affected. In this way, the redundancy of the transmission channel of the air-ground data flow can be improved, and the reliability can be improved.

[0035] Further, in a possible implementation, the first aggregation port and the second aggregation port may support load sharing, that is, air-ground data flow transmission is performed with the second switch through the aggregation port, including: When the data volume corresponding to the air-ground data flow exceeds the preset data volume, the air-ground data flow is transmitted through the first aggregation port and the second aggregation port at the same time.

[0036] It is possible to set a preset data volume, which reflects the data volume limit of the air-ground data flow per unit time. When the actual data volume of the air-ground data flow per unit time exceeds the preset data volume, data transmission only through the first aggregation port or only through the second aggregation port may cause excessive pressure on the aggregation port, resulting in transmission jams, packet loss, etc. The method provided by the present invention can realize load sharing under high load and ensure the transmission smoothness and integrity of air-ground communication data by transmitting the air-ground data flow through the first aggregation port and the second aggregation port at the same time when the data volume corresponding to the air-ground data flow exceeds the preset data volume.

[0037] Furthermore, in the method provided by the present invention, in order to ensure the reliability of the network, Figure 3 As shown, the first switch of the core network connecting the two communication technologies adopts stacking networking, that is, the first switch is a stacking switch, which includes a main switch and a backup switch, and the first communication tunnel and the second communication tunnel correspond to the main switch and the backup switch respectively. When there is a failure in the first communication tunnel, switching to the second communication tunnel to transmit the air-to-ground data stream between the aircraft control platform and the low-altitude aircraft includes: When the main switch fails, the backup switch is switched to carry out air-to-ground data stream transmission between the aircraft control platform and the low-altitude aircraft, wherein the main switch corresponds to the first communication tunnel, the backup switch corresponds to the second communication tunnel, and the main switch and the backup switch are stacked.

[0038] For stacked switches, if the master switch fails, another backup switch in the stack automatically switches to master, and the corresponding communication tunnels are switched together to ensure that air interface data is not affected.

[0039] In the ground-side networking (networking of the first switch and the second switch), the data center switches connecting the two core networks are stacked, and the data of the two core networks are connected to different switches in the stack, which can avoid single-point / single-switch failures. At the same time, the link aggregation mode is used for connection, and the ports of the first switch participating in the link aggregation come from different switches in the stack, which can improve the redundancy protection of the first switch and the second switch inside the aircraft control platform, and further improve reliability.

[0040] The method provided by the present invention is aimed at low-altitude aircraft air-to-ground communication. It designs the linkage design of wireless network primary-standby redundant networking and wired network multi-link redundancy for the first time, effectively solving the problems of resource waste, network storm, load increase, doubling of operating costs, etc. caused by dual-network communication. In addition, it realizes the combination and linkage of GRE tunnel technology, link aggregation technology and stacking technology for the first time in the field of low-altitude aircraft air-to-ground communication, realizing end-to-end redundant communication of air-to-ground wired and wireless networks. When the network encounters primary-standby switching, it automatically performs it, and the upper-layer business is not affected, which greatly improves the reliability of air-to-ground communication. Further, the mature GRE tunnel technology is used to effectively realize the decoupling of wired and wireless networks, increasing the universality of redundant networking solutions.
