Problems solved by technology
Long-term connections are often easily disturbed by the external environment, such as unstable network environment, network server downtime, etc.
Especially the unstable network environment is the most troublesome problem for many engineers
If the unstable network environment occurs in the operating environment of the unmanned airport, the client control terminal will not be able to successfully complete control events such as take-off, landing, and return of the aircraft, and the entire business process will be seriously affected

Embodiment Construction
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure.
[0044] figure 1 A schematic structural diagram of some embodiments of a communication system capable of providing more reliable network connection services in the present disclosure.
[0045] Such as figure 1 As shown, the communication system of this embodiment includes: a cluster composed of multiple network servers deployed in a distributed manner (referred to as a network server cluster) and a distributed application program coordination service. The Distributed Application Coordination Service is used to provide consistency services and distributed application election functions for network server clusters. The main network server elected from the network server cluster of distributed deployment provides network connection service for the client control terminal and t...

The disclosure proposes a communication method, device and system, a network server and a storage medium, and relates to the field of signal control. The communication method includes: the main network server elected from the network server cluster in distributed deployment provides network connection services for the client control terminal and the airport server, so that the client control terminal can send control commands to the airport server; the network connection provided by the main network server The service includes: establish a first connection with the client control terminal; establish a second connection with the airport server; continuously send heartbeat packets to the airport server on the second connection, so that the airport server closes the second connection; when it is detected that the second connection is closed and the preset business rules are satisfied, the re-election process of the primary network server is triggered, so that the newly elected primary network server can continue to provide network connection services. Thus, a more reliable network connection service is provided for the client control terminal and the airport server.
Description
technical field [0001] The present disclosure relates to the field of signal control, and in particular to a communication method, device and system, a network server and a storage medium. Background technique [0002] During the signal interaction process between the client control terminal and the airport server, they usually establish a long connection and transmit signals based on the long connection. The long connection is often easily disturbed by the external environment, such as unstable network environment, network server downtime and so on. Especially the unstable network environment is the most troublesome problem for many engineers. If the unstable network environment occurs in the operating environment of the UAV airport, the client control terminal will not be able to successfully complete control events such as take-off, landing, and return of the aircraft, and the entire business process will be seriously affected. Contents of the invention [0003] One o...
