Wireless network architecture in passenger train

Abstract

The invention relates to a wireless network architecture in a passenger train. The wireless network architecture is mainly composed of a vehicle-mounted server, a wireless controller, a satellite antenna, a modulator-demodulator, a wireless access point, a WIFI suspended ceiling antenna and train side connectors. The satellite antenna is connected with the wireless access point through the modulator-demodulator so as to achieve both-way communication between the external Ethernet and the vehicle-mounted server and achieve the function of communication between the external Ethernet and the vehicle-mounted server. The vehicle-mounted server is used for receiving passenger train running state information transmitted by a passenger train running state monitoring system and receiving service request information forwarded by the wireless access point, the WIFI suspended ceiling antenna sends the passenger train running state information and the passenger train service information to wireless client terminals through the wireless access point, and therefore different requirements of passengers for passenger train services on the vehicle-mounted server are met. Information interaction between the wireless client terminals in carriages is achieved through the train side connectors between the carriages, and networked and intelligent management of the carriages of the passenger train is improved.

Description

technical field [0001] The invention relates to the field of railway passenger car passenger service, in particular to a wireless network architecture in a railway passenger car. Background technique [0002] Railway passenger cars are the main vehicles for carrying passengers. At present, the railway passenger car service system in my country mostly adopts one-way push technology. The passenger information services of railway passenger cars are still at the level of manual broadcasting and in-car information display. Passengers can only passively accept the information provided by the train. It is impossible to select service information according to personal preferences, and the amount of service information is limited, and information interaction between passengers and flight attendants cannot be realized. Especially with the rapid development of mobile Internet technology, the number of passengers with smart terminal devices continues to expand, especially in passenger ca...

[0002] Railway passenger cars are the main vehicles for carrying passengers. At present, the railway passenger car service system in my country mostly adopts one-way push technology. The passenger information services of railway passenger cars are still at the level of manual broadcasting and in-car information display. Passengers can only passively accept the information provided by the train. It is impossible to select the service information according to personal preferences, and the amount of service information is limited, and it is impossible to realize the information interaction between passengers and flight attendants

Especially with the rapid development of mobile Internet technology, the number of passengers with smart terminal devices continues to expand, especially in passenger cars. Although most passengers carry smart terminal devices such as mobile phones, notebooks, and IPADs, the above-mentioned smart terminal devices cannot Communicate with the bus service system, that is, passengers cannot enjoy train services through Internet terminals such as PCs and mobile phones, which seriously affects the comfort of passengers and the commercial value of the service system itself
