Description
Technical field
The invention belongs to information systems technology fields, and in particular to a kind of passenger information system and control method.
Background technique
With the development of modern railway transportation technology, train convenience, in terms of propose higher want
It asks and the trend of global networking, very necessary using passenger information system in high-speed EMUs, the passenger information in China
Systems technology more falls behind than western developed country, and R & D design passenger information system with independent intellectual property rights especially must
It wants, realizes passenger information display system, the passenger's intercommunication broadcast system, passenger entertainment system for meeting bullet train requirement, and real
Now with the communication of train network monitoring, it is of great significance.
Railer's information system makes trains distributing formula service system, including broadcast system, video system, interior intercommunication system
System etc., with the fast development of city underground and light rail, passenger information system has been widely applied on each train multiply
Visitor provides easily information on services by bus.Passenger information system main control unit is used to control the work of passenger information system, such as
Arrival information, playing audio-video entertainment etc. are broadcasted in control.In general, a train is only equipped with a driver, therefore, when master control list
When member breaks down, it can only manually be broadcasted by driver and notify passenger's arrival information, this will influence driver and drive to bring
Security risk.The main method for solving the problems, such as this is the main control unit of configuring redundancy.In existing part of the train, train is equipped with two
A main control unit.It is conflicted with each other in order to avoid two hosts manage sub- equipment simultaneously, in the prior art, the work of two main control units
Operation mode an are as follows: main control unit calculates (such as audio/video decoding, arrival information calculating etc.) as host, to execution information
It works with system control (such as audio-video casting), and another main control unit is in standby as slave, is not executed and is appointed
What works.When a host breaks down, another host is just taken over, and execution information analytical Calculation and system control work
Make.And the information feedback between two main control units can have message delay, and the switching from slave to Host Status also needs
Time delay is wanted, therefore, master-slave swap certainly exists adapter tube delay, arrives at a station it is possible that failing to report for a period of time after hostdown
The problem of information.
Summary of the invention
The object of the present invention is to provide a kind of passenger information system and control methods.Passenger information system of the present invention includes mutual

Store up passenger information storage unit；
(2) the main control unit connection in slave status is cut with passenger information storage unit, state detection unit and state
The connection of unit is changed, the passenger information of passenger information storage unit is obtained, but does not execute passenger information system management work；
(3) when the main control unit under Host Status loses Host Status, state detection unit detects signal simultaneously
The main control unit in slave status is switched to Host Status by status toggle unit, passenger information system is executed and manages work
Make, audio, video data is transferred to audio-video output unit by passenger information system management unit, and audio-video output unit passes through
Function control unit controls passenger entertainment terminal；Passenger information system management unit is by information data transmission to information processing list
Member, information process unit control passenger information display terminal by function control unit, and passenger information system management unit is by sound
Frequency evidence is transferred to Audio control unit, and controls passenger's intercommunication broadcast terminal by Audio control unit, while should be in master
The passenger information of the main control unit of machine state is stored to passenger information storage unit.
Beneficial effects of the present invention are as follows:
Passenger information system of the present invention is in order to avoid the first main control unit and the second main control unit while management terminal is mutual
Conflict, the operating mode of two main control units are as follows: a main control unit is as host, to execute passenger information system management work
Make, another main control unit is also at working condition as slave, but does not execute passenger information system management work, only together
Step obtains the passenger information of passenger information storage unit, and passenger information storage unit is constantly in working condition, as a master
Machine breaks down, and state detection unit detects signal and another main control unit is switched to host by status toggle unit
State, the host from passenger information storage unit obtain passenger information go forward side by side traveller visitor's information management work, avoid principal and subordinate and cut
It changes in the presence of adapter tube delay, it is possible that the problem of failing to report arrival information after hostdown for a period of time.
