It is main control module, and real-time monitoring principal series is to realize handoff functionality.
Logging modle: monitoring record information, accident condition information and the relevant device in record train travelling process in real time
Information etc..Logging modle passes through industry ethernet, same to main control module, man-machine interaction unit, expanding element communication.Logging modle is
Non-security module is taken redundancy structure, can be communicated between two logging modles, guarantees dump data integrity with this, improves data
Availability；
Secure digital output module: No. 8 relays output, every road relay all export normally opened and normally closed two groups of dry contacts and supply
Using selection；
Secure communication module: realize that the physical layer protocol between peripheral hardware, secure communication module carry out the data of peripheral hardware
Main control module is sent to after closing frame；
Safety frequency input module: the acquisition of 8 road speed sensor signals is realized；
It is non-security to simulate into module out: to be mainly used for the acquisition of 8 road pressure signals, 1 road Chai Su (diesel engine speed sensing
Device) acquisition, the acquisition of original edge voltage and primary current, the acquisition of 1 tunnel radar signal, the output of speed per hour, speed limit and mileage；
Secure digital input module: the acquisition of 16 way switch amounts, i.e. train 110V switching value information etc. are realized；
Ethernet switching module: industry ethernet linkage function is realized.
Shown in Fig. 2, man-machine interaction unit, be realize human-computer dialogue, train operation monitoring visualization interface function, it is real
Both-end or single-ended configuration can be taken in the application of border.In addition to man-machine interface, man-machine interaction unit also provides debugging and maintenance interface, leads to
The software of main computer unit, man-machine interaction unit, expanding element can be upgraded by crossing debugging interface, can be realized by maintenance interface to master
Basic data in machine unit is safeguarded.
Shown in Fig. 2, expanding element integrates the interface of the existing peripheral hardware of LKJ, as plane radio shunting lamp shows interface box, speed passes
Sensor etc., and the interfaces such as multichannel Ethernet, CAN, RS422 are provided, for external equipment or relevant device extension connection.Extension is single
Also the communication between each module is realized using redundancy CAN FD bus in first inside.In addition to Peripheral Interface, expanding element also provides debugging
And maintenance interface, but it is different from main computer unit and man-machine interaction unit, expanding element using communication realize debugging and
Maintenance interface can upgrade the software of main computer unit, man-machine interaction unit, expanding element by wireless debugging interface, pass through nothing
Line maintenance interface can safeguard the basic data in main computer unit.The wireless communication module of expanding element, using wireless
Secure communication protocols use transparent transmission mode to wireless data, i.e., only ensure to receive the errorless of data, not to the secure communication of data
Agreement is parsed, and the wireless data received is sent directly to main computer unit, carries out dissection process by main computer unit.
In Fig. 3, main computer unit, man-machine interaction unit, the connection communication mode between expanding element are according to the present invention
One embodiment, as an example, not a limit, external equipment connection can be adjusted according to practical application.
Main computer unit, man-machine interaction unit are communicated using industry ethernet between expanding element, triangular connection communication
Mode specific embodiment is as follows:
1., the logging modle and man-machine interaction unit of main computer unit: logging modle can be according to man-machine interaction unit for interface
Dump command, outgoing dump data；
2., the logging modle and expanding element of main computer unit: the data of record are sent to extension list to interface by logging modle
Member is sent to the relevant devices such as TAX, LAIS after expanding element processing；
3. interface, the main control module and man-machine interaction unit of main computer unit: realizes real-time display, the people of train operation monitoring
The functions such as machine dialogue；
4., the main control module of main computer unit is with expanding element: realizing the function of communicating with portion of external equipment for interface；
5., the main control module of main computer unit and the logging modle of main computer unit: main control module will need the number that records to interface
According to being sent to logging modle and record in real time such as monitoring record information, the accident condition information in train travelling process；
The system structure of CANFD internal bus combination Ethernet external bus of the present invention, with the CAN bus of existing product,
Flexray bus is different.Compared to existing technology, CANFD bus has higher effective traffic load, faster transmission rate, letter
List simultaneously flexibly configures, and the CRC algorithm of CANFD optimization, and anti-interference ability is stronger, is more suitable for railway complicated applications field
Scape.And industry ethernet can satisfy that larger data transmission, speed is fast, configuration is flexible.The specification configuration of interior external bus, is conducive to
Data are effectively treated, and reduce redundancy processing, improve the performance of system.The bus configuration of redundancy can greatly improve system
The reliability and availability of communication.
And flexibly, the debugging interface of multiplicity and existing product the characteristics of not having.The utility model LKJ system can pass through
The debugging interface of any one unit in system, the software upgrading of whole units in realization system, while the expansion of the utility model LKJ system
The distinctive wireless debugging interface of unit is opened up, another form of debugging interface is provided, when practical application can select according to field condition
It is suitble to the interface of field application environment to be installed and safeguarded, greatly improves installation and the maintenance efficiency of LKJ system.
In addition, flexible maintenance interface, can be realized by the maintenance interface of any one unit in LKJ system to master control
Basic data in unit changes the outfit, and is the characteristics of existing product does not have, and greatly improves the efficiency that LKJ system data changes the outfit
And reliability.
The wireless communication module of expanding element uses wireless security communication protocol, is directly transmitted to data using transparent transmission mode
It is the characteristics of existing product does not have to main computer unit, i.e., wireless communication module is to the software document or base to be upgraded received
Plinth data file, the security protocol without data itself parse, and only dock the data of received correct, directly total by Ethernet
Line is sent to main computer unit.The advantages of such transparent transmission communicates is, when variation has occurred in the security protocol of data, it is only necessary to update
The software of main computer unit main control module, the software of the wireless communication module without updating expanding element, reduces the dimension of LKJ system
Shield and update difficulty.
The foregoing is merely the preferable case study on implementation of this new departure, are not intended to limit the protection model of this new departure
It encloses.All any modification, equivalent replacement, improvement and so within the spirit and principle of this new departure, it is new to should be included in this
Within the protection scope of scheme.
