Description
Technical field
The present invention relates to a kind of rail traffic LTE-M communication system Train Control business transmission big data monitoring system and
Method belongs to the rail traffic communications field.
Background technique
Rail traffic is communicated using LTE-M (LTE-Machine-to-Machine, the technology of Internet of things based on LTE evolution)
System bearing CBTC（Communication Based Train Control, communication-based train control）, train operation
The data service of status monitoring, or carry wireless train dispatch simultaneously, (Closed-Circuit Television, is closed CCTV
Road TV monitor system), PIS (Passenger Information System, passenger information system), urgent text etc. other
Business.In order to ensure train operating safety, relevant regulatory requirements CBTC data have the priority of highest level.It is most prominent at present
The problem of lack CBTC data preferential reliable transmission there is no effective monitoring means.It is existing to pass through DCS (Digital
Communication System, digital communication system) network management system is hard mainly for monitoring device come the method for chasing after north failure
Failure, be unable to monitor LTE-M big flow wireless communication due to electromagnetic interference, signal decay etc. generate transient time delay, packet loss,
Switch the failures such as unsmooth, therefore there are O&M departments when train control system failure promptly and accurately to judge that the source of trouble goes out
Still come from other equipment from LTE-M communication system, this brings biggish hidden danger to CBTC operation and maintenance.Because of a kind of energy of the invention
The method of data flow is very important when enough real-time monitoring multi-business communication system carrying important services.
Summary of the invention
It is an object of the invention to provide a kind of rail traffic LTE-M communication system for deficiency existing for prior art
The big data of Train Control business transmission monitors system and method, it is ensured that CBTC system operates normally, real-time monitoring rail traffic
The reliability that CBTC business is transmitted in multi-business communication system, by the total data that runs LTE-M core net side with
Service terminal side crawl, analysis, sort out, excavate, extract, report, one side real-time rendering system operation conditions, and by with
Train Control business flowing water compares, the operating status of real-time monitoring LTE-M system.On the other hand event occurs in train control system
In the case where barrier, the working condition of relevant time period LTE-M is provided, and by comparing with Train Control business flowing water, to judge
The reason of failure, is attributed to LTE-M communication system or is attributed to train control system other equipment.
In order to illustrate the present invention, need to have it is assumed hereinafter that：
1) multiple services carrying is realized using LTE-M wireless communication technique in rail traffic.
2) business of LTE-M carrying includes CBTC and other business.
3) CBTC data service is passed using UDP (User Datagram Protocol, User Datagram Protocol) mode
It is defeated.
4) car-mounted terminal that LTE-M system is installed ON TRAINS passes through interchanger and multiservice interface.
5) LTE-M system passes through interchanger and multiservice interface in the equipment of the core network that route control centre installs.
In order to achieve the above objectives, present inventive concept is：Pass through the Train Control CBTC business for carrying LTE-M communication system
Data are in core net side and the crawl of car-mounted terminal side, analysis, classification, excavation, extraction, report, and on the one hand presentation is in real time
System operation conditions, and by being compared with Train Control business flowing water, the operating status of real-time monitoring LTE-M system；On the other hand
In the case where train control system breaks down, provide the working condition of relevant time period LTE-M, and by with Train Control industry
Flowing water of being engaged in compares, and to judge failure the reason of comes from LTE-M communication system or comes from train control system other set
It is standby.
Conceived according to foregoing invention, the present invention adopts the following technical solutions：
1, a kind of big data of rail traffic LTE-M communication system Train Control business transmission monitors system, including equipment：Line

Method real-time rendering system operation conditions, and by being compared with Train Control business flowing water, the operation shape of real-time monitoring LTE-M system
State；In the case where train control system breaks down, provide the working condition of relevant time period LTE-M, and by with train control
Whether the reason of business flowing water processed compares, and judges the failure comes from LTE-M communication system；LTE-M carries the data transmission of CBTC
The available big data monitoring in real time comprehensively of information, belongs to the first management means of CBTC system operation and maintenance, is conducive to improve column
The traffic safety of vehicle.
A kind of big data monitoring method of rail traffic LTE-M communication system Train Control business transmission, using according to power
Benefit requires the big data monitoring system of the rail traffic LTE-M communication system Train Control business transmission to be operated, and grasps
Steps are as follows for work：Connection line center monitors unit and core network switches connect vehicle-mounted monitoring unit and vehicle-mounted interchanger；?
In wire center monitoring unit, CBTC monitoring host is sent to after sorting data into, in vehicle-mounted monitoring unit, after sorting data into
It is sent to CBTC monitoring host；Heart CBTC is monitored in host and vehicle-mounted CBTC monitoring host and is equipped with database, storage in the line
CBTC data or other business datums；CBTC data flow is formed in the heart and vehicle-mounted CBTC monitoring host in the line, and draws biography
Defeated time delay writes out the packet loss and time delay report document of CBTC data flow；In the line in the heart and vehicle-mounted monitoring host, A, B are provided
Two net propagation delay times, the comparison report document of packet loss；Vehicle-mounted LTE terminal will occur for train between different LTE base stations in advancing
Access handoff procedure.Wire center monitors the data information in host and vehicle-mounted monitoring host extraction A net and B net handoff procedure,
Packet loss in handoff procedure is generated, time delay information and forms report file whether handover success etc.；Vehicle-mounted monitoring host will be every one
It fixes time and uploads main report to path monitoring host, and provide the report file of the RAMS index of LTE-M.
Compared with prior art, the present invention has the characteristics that following obvious high-lighting and significant technological progress:?
The preferential reliable transmission that current most distinct issues lack CBTC data in LTE-M does not have effective monitoring means.It is existing logical
DCS network management system is crossed to chase after the method for north failure mainly for monitoring device hard fault, is unable to monitor LTE-M big flow channel radio
Believe due to transient time delays of generation such as electromagnetic interference, signal decaying, packet loss, switch the failures such as unsmooth, there are train controls
O&M department can not promptly and accurately judge that the source of trouble comes from LTE-M communication system and still comes from other and set when system processed breaks down
Standby, this brings biggish hidden danger to CBTC operation and maintenance.Because the invention one kind being capable of the carrying of real-time monitoring multi-business communication system
The method of data flow is very important when important service.
