in the case of unmanned driving, the vehicle-mounted broadcasting system realizes the following 3 functions through an interface with a vehicle-ground wireless system:
1) broadcasting planned passenger notification in the automatic driving mode of the vehicle;
2) the driver broadcasts on site in a manual mode;
3) an Operation Control Center (OCC) dispatcher remotely and manually broadcasts.
2. Two-way voice communication between the passenger and the control center.
The emergency alarm is arranged at the position of a car door of each carriage, and the channel of the wireless communication system is utilized, so that the function of broadcasting the car by a dispatcher in the existing line center can be realized through the interfaces of the vehicle-mounted broadcasting system and the wireless communication system, and the function of two-way communication talkback between passengers and the dispatcher in the control center or a control console in a cab of the car can also be realized.
3. Images in front of, inside of and along the running vehicle are provided for control center dispatcher personnel.
As the closed arrangement of a cab is cancelled, video monitoring equipment with an infrared night vision function is additionally arranged at the head and the tail of the vehicle and is used for enhancing the monitoring of the front and the back of the vehicle and recording accident information, so that the accident reason can be conveniently analyzed in the future; when the vehicle has a fault, the auxiliary control center remotely controls the vehicle to creep to a line to be avoided and a station. The captured images are uploaded to a control center through a vehicle-ground communication interface or stored in a vehicle local hard disk.
4. In-vehicle video monitoring linkage function
Under the full-automatic driving condition, the monitoring information of the vehicle and the alarm information of special events are collected through the TCMS, such as door handle action, fire alarm and the like. The position information of the emergency alarm in the vehicle, the fire alarm position information and the related reset information can be uploaded to the control center through the vehicle-ground wireless system during linkage, and after the linkage is triggered by the emergency alarm, the braking and fire alarm transmitted by the TCMS and the like, the PIS vehicle-mounted CCTV system actively uploads the monitoring video of the corresponding camera to the control center for display.
5. Enhancing status monitoring of vehicle-mounted communication devices
The ground integrated monitoring system (ISCS) needs to monitor the states of vehicle-mounted wireless, CCTV and PIS equipment. Self-checking and fault information of a train-ground wireless system and a PIS are transmitted to a TCMS through an interface of a vehicle, the TCMS manages vehicle-mounted equipment information in a unified way, and the information is transmitted to the ground through train-ground wireless communication, such as a comprehensive monitoring system and an ATS system.
