Description
Technical Field
The utility model relates to a passenger emergency intercom system especially relates to a passenger emergency intercom system based on wireless broadband network.
Background
With the development of science and technology, modern transportation means such as unmanned automobiles, subways, passenger cars, trains and the like are more and more popularized, and because no driver talkbacks the passengers in an emergency mode, the dispatching desk of a line generally directly talkbacks the passengers on the vehicles directly through wireless equipment. Conventional narrowband trunking systems, such as narrowband networks like Tetra or GSM-R, typically use semaphores as audio transmission devices, while facilitating Tetra's wireless data communication to complete passenger emergency intercom request applications and calls.
The conventional narrowband cluster system has the following disadvantages:
1. multi-way calling cannot be carried out, and only one-to-one half-duplex or full-duplex audio conversation can be carried out.
2. The system does not support multi-dispatching simultaneous conversation or transfer service, and the dispatching is not flexible.
3. It is inconvenient for free switching of multi-way calls and call holding.
4. Simultaneous emergency talk-back for multiple passengers is not supported.
5. Video calls are not supported.
Chinese patent publication No. CN108819984A discloses a passenger alarm output control circuit for an unmanned subway train, which comprises a passenger emergency alarm installed on the train, the passenger emergency alarm having an alarm button and alarm relays with normally closed contacts linked with the alarm button and in one-to-one correspondence, when the alarm button is pressed, the alarm relays are powered on to disconnect the normally closed contacts, the normally closed contacts of the alarm relays of each passenger room are connected in series to form an emergency alarm line, and two ends of the emergency alarm line are respectively connected to a train power supply and an input/output module of a TCMS of the passenger room. When the passenger information system works normally, the passenger information system can transmit alarm signals through a communication network and also can transmit the alarm signals through a hard wire, and when the signals of the passenger information system and the hard wire are inconsistent, the hard wire alarm signals are prior. When the network is interrupted, the hard-line alarm signal is used as redundancy and still can output the alarm signal, thereby greatly improving the reliability of the system. The utility model is directed to the reliability of the alarm system rather than the multiplexing of the emergency intercom system.
