Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of airport ground equipment, and specifically relates to an airport ground equipment internet of things networking system. BACKGROUND

[0002] In the field of existing airport ground equipment, according to the requirements of regulations, each airport ground equipment should be installed with an internet of things client device, and the airport ground equipment completes communication with a server through the internet of things client device to access the internet of things system. The existing internet of things client device and the server basically adopt a point-to-point mode for communication, and the entire network structure belongs to a star-shaped topological structure. The existing communication between the internet of things client device and the server is usually realized in a TCP long connection mode.

[0003] This communication mode has the following disadvantages: first, the existing communication mode is unstable. Whether the internet of things client is powered off, dead, crashes, or restarts, or the network is disconnected, it will affect the communication between the internet of things client device and the server. Second, in actual application, due to the special environment of the airport, such as culverts, corridors, terminal buildings and other facilities, the network signal will be blocked, which will cause the attenuation or even interruption of the network signal, affecting the communication between the internet of things client device and the server. Third, in the airport area, the site is wide and the base stations are few. The long-distance walking of the airport ground equipment will cause the signal switching between mobile base stations and other actual situations, which will often cause the TCP long connection to be disconnected. Fourth, with the gradual entry of unmanned technology into the field of airport ground equipment, the informatization of airport ground equipment is also required. The airport ground equipment needs to form a network and complete data exchange and information sharing. The existing communication mode does not meet this requirement. Fifth, more and more intelligent upper equipment is installed on the airport ground equipment, which needs to obtain information through message subscription (such as subscribing to high-precision positioning information from the positioning module and subscribing to vehicle bus data from the data acquisition module). The existing communication mode does not meet this requirement. UTILITY MODEL CONTENT
