Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and more particularly to a passenger intercom system with scene setting function and its control method. Background Technology

[0002] With the rapid development of urban rail transit, passengers are placing increasingly higher demands on the comfort and safety of trains. As an important component of the train broadcasting system, the passenger intercom allows passengers to communicate with the driver in unexpected situations, such as fires, floods, and violent attacks, to report emergencies. This enables the driver and control center to respond promptly and minimize losses caused by the incident.

[0003] The existing technology offers the following solutions to the above problems:

[0004] Four passenger emergency alarm devices are installed in appropriate locations in each passenger compartment. The emergency alarm devices have simple and clear operating instructions for easy passenger use. In an emergency, a passenger can trigger the alarm button to alert the driver. Once triggered, the alarm status of the emergency alarm device is indicated by an indicator light on the driver's cab broadcast control box, accompanied by a prompt tone. The emergency alarm intercom does not affect the playback of pre-recorded announcements on the train. The driver can use the "PC" control button on the broadcast control box to select and communicate with the passenger who has triggered the alarm; the conversation uses full-duplex mode. During the conversation, the driver can also interrupt the call with the passenger by pressing the "PC" control button again, resetting the triggered emergency alarm device. However, this solution has the following drawbacks:

[0005] 1) The passenger intercom function is only effective in one scenario and has only one control method. Its function is limited and cannot meet the specific needs of special scenarios, thus affecting the efficiency of emergency handling.

[0006] 2) In maintenance scenarios, the passenger intercom function cannot be activated, and the onboard cleaning and maintenance personnel cannot communicate with each other in real time, which is not conducive to the smooth operation of cleaning and maintenance plans.

[0007] 3) There is no intercom function between the crew and other passenger compartments. In the event of an emergency, the crew and passengers will not be able to understand the situation of the whole train and other passenger compartments in a timely manner, which may easily transmit incorrect information to the driver or other passengers and cause secondary hazards.

[0008] 4) The cabin is not equipped with a flight attendant announcement system. In the event of an emergency, the flight attendant will not be able to comfort the passengers in time, which may easily cause negative emotions among the passengers and create a chain reaction in the media. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides a passenger intercom system with scene setting functionality and its control method. This invention employs effective control strategies and methods, which not only prevent train delays caused by unforeseen events but also ensure the overall conditions for passenger evacuation and the convenience of rescue in the event of an emergency; it reduces the probability of train delays while ensuring normal train operation efficiency, and simultaneously improves train operation quality, punctuality control capabilities, and operational service reliability.
