An urban rail transit talkback calling system

Abstract

The invention discloses an urban rail transit talkback calling system. The invention belongs to the technical field of intercom calling systems. The invention discloses an urban rail transit talkbackcalling system. The system comprises an in-vehicle terminal device, a vehicle-ground interconnection network and a ground operation and maintenance management center. The in-vehicle terminal device comprises a terminal calling device and a terminal answering device. The vehicle-ground interconnection network comprises a 3 / 4G wireless network and a field station WIFI. The ground operation and maintenance management center comprises a log system, an equipment network manager, a content server and a short message interface, The terminal calling device is in signal connection with the terminal answering device, so communication between passengers and drivers or attendants can be realized conveniently; meanwhile, the vehicles, the stations and the ground are interconnected, so that the responsespeed of emergency events is greatly increased, malignant events in urban rail transit can be avoided to a great extent, harmonious development of the rail transit is facilitated, and the user experience of passengers can be greatly improved.

Description

technical field [0001] The present invention relates to the technical field of intercom calling system, more specifically, relates to an urban rail transit intercom calling system. Background technique [0002] Urban rail transit is the backbone of urban public transportation. It has the characteristics of energy saving, land saving, large transportation capacity, all-weather, no pollution (or less pollution) and safety. It is a green and environmentally friendly transportation system, especially suitable for large and medium-sized cities. Urban rail transit is a large-capacity rapid public transportation system that uses electric energy as the main power source and adopts a wheel-rail operation system. It is mainly responsible for barrier-free and short-distance passenger transportation, usually with light EMUs or trams as the carrier, effectively relieving the traffic pressure of dense passenger flow in the city. [0003] The rail transit in the city has a variety of syst...

AI Technical Summary

Problems solved by technology

[0004] Urban rail transit cars are generally not equipped with flight attendants, and they all get on and off the car independently. The order and sanitation in the car also need to be conscious of the passengers, but occasionally conflicts will occur between passengers, for example, it is occasionally reported in the news In the case of passengers hitting people, due to the inability to communicate with the flight attendants in time, similar vicious incidents cannot be stopped in time. In severe cases, passengers may be seriously injured, which is not conducive to social harmony and will seriously affect the user experience of passengers.
