Problems solved by technology
[0002] Passenger information on the subway (such as station information, etc.) is generally displayed to passengers through LCD (liquid crystal display), IDU (internal display), MDU (dynamic map display unit) and other equipment. However, if the passenger flow on the train is large, The space is crowded, and passengers cannot see the information of some stations, and the phenomenon of wrong station or missing station is prone to occur, or passengers cannot find the direction of the train in time, which brings great inconvenience to travel

Embodiment Construction
[0013] Below in conjunction with embodiment the present invention is described in further detail.
[0014] Rail transit vehicle-mounted passenger information transmission system based on WiFi technology, including the main controller and switchboard located in the driver's compartment, each compartment is equipped with a WiFi module, passengers have mobile phone clients with installed applications, the switchboard and vehicle-mounted WiFi Module interface definitions are shown in Table 1, and the WiFi module transmits vehicle passenger information to the mobile phone client, wherein the mobile phone and WiFi module interface definitions are shown in Table 2, and the mobile phone client parses and displays the vehicle passenger information.
[0015] The main controller encodes the received on-board passenger information using XML (Extensible Markup Language) language, and sends it to the intra-train LAN through UDP (User Datagram Protocol) broadcast packets. The format of the XM...

The invention relates to a rail transit on-board passenger information transmission system based on the WiFi technology. The rail transit on-board passenger information transmission system is used for transmitting on-board passenger information to a mobile client side of each passenger and comprises a master controller and a switch which are arranged in a cab, wherein a WiFi module is arranged in each compartment, and each passenger carries the mobile client side with an application program installed. The master controller transmits the on-board passenger information to a local area network in a train after acquiring the on-board passenger information, the switch receives the on-board passenger information and forwards the on-board passenger information to the WiFi module in each compartment, the WiFi module transmits the on-board passenger information to the corresponding mobile client side, and each mobile client side analyzes and displays the on-board passenger information. By means of the rail transit on-board passenger information transmission system based on the WiFi technology, the on-board passenger information can be transmitted to mobile client sides of passengers in real time so that the passengers can know about running and arrival situations of the current train.
Description
technical field [0001] The invention relates to a rail transit vehicle-mounted passenger information transmission system based on WiFi technology, which is used for transmitting vehicle-mounted passenger information to passenger mobile phone clients, and belongs to the field of applied communication. Background technique [0002] Passenger information on the subway (such as station information, etc.) is generally displayed to passengers through LCD (liquid crystal display), IDU (internal display), MDU (dynamic map display unit) and other equipment. However, if the passenger flow on the train is large, The space is crowded, and passengers cannot see some station information, which is prone to wrong or missing stations, or passengers cannot find the direction of the train in time, which brings great inconvenience to travel. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a rail transit on-board passenger information tra...
