Embodiment Construction

[0031] The UAV ground station bus system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] figure 1 It is a topology diagram of the UAV ground station bus system according to an embodiment of the present invention. Such as figure 1 As shown, the UAV ground station bus system in this embodiment may include a control terminal 100 , a server 200 , a ground data link terminal 600 , a first Ethernet switch 301 , and a second Ethernet switch 302 .

[0033] The control terminal 100 is used to process the interactive information transmitted between the ground station and the UAV, and the control terminal 100 may specifically be a computer of a certain type. There may be multiple control terminals 100, and each control terminal 100 may process different interaction information; it should be noted that the processing of interaction information includes means of generating, sending, and receiving interaction information. ...

Abstract

The invention discloses a UAV ground station bus system, relates to the technical field of UAV ground stations, and can solve the problem of poor reliability of the UAV ground station bus system. The UAV ground station bus system includes a control terminal, a server, a ground data link terminal, a first Ethernet switch and a second Ethernet switch, and the control terminal and the server are respectively connected to the first Ethernet switch and the second Ethernet switch , and the first Ethernet switch is connected to the second Ethernet switch. In the UAV ground station bus system of the present invention, the interactive information can be transmitted according to a suitable message transmission path. When one set of physical subnetwork equipment fails and shuts down, the system can be automatically reconfigured, and another set of physical subnetwork equipment can be used. Continue to deliver information to further improve the reliability of information transmission in the bus system.

Description

technical field [0001] The invention relates to the technical field of UAV ground stations, in particular to a UAV ground station bus system. Background technique [0002] At present, most UAV ground station bus systems use two physically independent IEEE802.3Ethernet A and B buses as redundant information exchange carriers. However, the information transmission quality of this type of scheme is not high and the reliability of the system is poor. The details are as follows: 1) The transmission delay of key command signaling cannot be guaranteed at the protocol layer, and the delay of key commands is uncontrollable; 2) The discrete bus cannot form Real-time hot backup, low reliability index; 3) Bandwidth cannot be shared across buses, resulting in waste of transmission resources; 4) Reconfiguration of bus failure requires software and hardware reconfiguration, which takes too much time (tens of minutes), causing delays. Contents of the invention [0003] An object of the p...
