Description
Technical Field
The invention relates to the technical field of unmanned broadcasting, in particular to a voice cluster control equipment system applying a subway control center.
Background
With the rapid development of urban modernization and economic construction in China, the process of urbanization is gradually accelerated, and the contradiction between supply and demand of urban traffic becomes increasingly tense. Ground transportation has not been able to accommodate the ever-increasing traffic demands of economic activities and people's lives. Road congestion and traffic order confusion have become the "bottleneck" problem that restricts urban development. Therefore, the construction of subways becomes a first choice for solving the passenger flow transportation pressure of each big city, and railways are well-established all over the country.
In order to create a safer, more convenient and more comfortable rail transit system, subway users in various regions also put higher requirements on vehicle operation, namely full-automatic unmanned driving. Under the background of such demands, it is a great trend that the subway vehicle realizes unmanned driving. The vehicle has no driver, and a part of functions originally borne by the driver are necessarily transferred to the operation command center, so that the monitoring work of train operation and the handling of emergency events need to be borne by the operation command center. How to realize the effective monitoring of the train in the unmanned operation and send the broadcast is very important and urgent for the communication with the passengers in the emergency.
In order to solve the problems, the adopted scheme is that radio station talkback equipment is deployed in an operation command center, a radio signal base station is erected along a railway, a vehicle-mounted radio receiving station is installed on a train, and the vehicle-mounted radio station is in butt joint with a vehicle-mounted passenger information system. The audio information of the operation command center is played to passengers through a channel of 'central radio station-wireless base station-vehicle radio station-vehicle passenger information system'. The biggest disadvantages of this solution are: firstly, manual broadcasting issuing can cause vehicle passengers to clearly know the broadcasting content because a broadcaster clearly tells words, and the environment noise of radio signals and the like; if the audio used by various scenes is prerecorded and stored on the vehicle, when an emergency happens, the vehicle is remotely controlled to play a specified audio file. The playing effect is not interfered by the noise of the wireless transmission channel, and the information transmission failure caused by unclear words spitting of the announcer is avoided; secondly, the emergency message can not be issued, when an emergency happens, the carriage is easy to be confused, the broadcasting effect is interfered, and if the display equipment in the carriage can display the emergency broadcasting words while broadcasting the emergency broadcasting, the information transmission efficiency is greatly improved; the emotion states of passengers in the carriage cannot be observed and monitored, and the dynamic direction of the internal events of the carriage cannot be mastered in emergency; fourthly, the emergency visual talkback between the passengers and the operation center cannot be realized; the function is single, has left many potential safety hazards for train operation.
