Description
Technical field
The invention belongs to the communications field, and in particular to a kind of time triggered agreement (TTP) bus network adds online
Carry configuration and monitoring method.
Background technology
Time triggered agreement (TTP) bus is a kind of high speed, the binary channels scene transmitted without master control, multi-endpoint
Bus communication protocol bus, with less integrate-cost, strict deterministic communication and low life cycle into
This features such as, can for intelligence control system provide distributed security it is crucial, it is strong when calculate and network application.
In aviation or other safety-critical fields, the application of time triggered agreement (TTP) bus is more and more extensive,
Society of automotive engineers (SAE) is indexed to TTP buses in AS6003 standards.
TTP buses realize communication using a kind of time division multiple access (TDMA) scheduling scheme.The TDMA cycles have
There is identical length, a TDMA cycle is divided into multiple time slots with flexible length again.In communication system
Each LRU have a time slot (sending time slots), and different frames letters are sent in each TDMA cycle
Breath.Message time arranges the characteristic related to the configuration of SNA and other securities, depends on and disappears
Breath descriptor list (MEDL).MEDL tables are defined in design time, by certain method by under it
It is downloaded in each node (LRU), TTP controllers are carried out with main frame and other TTP nodes (LRU) with it
Autonomous communication.Therefore the loading configuration of MEDL tables is essential for the exploitation of TTP bus systems.Equally,
Data in TTP buses are comprehensively and effectively monitored with the message time arrangement to system development, system network
The checking of network framework also plays the role of particularly important.
At present, TTP buses MEDL table loading configuration mainly has two methods, and one kind is point-to-point loading side
Formula, i.e., loaded respectively one by one to each node in TTP buses, and another kind is in system development
Increasing a set of Maintenance bus in system in addition, MEDL table loadings being carried out by Maintenance bus, former approach is
Not on-line loaded, for the system of multiple nodes composition, it is necessary to carry out once individually loading to each node,
Take time and effort, and easily malfunction, the multiple renewal of MEDL tables, later approach during being not easy to system development
Needs additionally increase a set of Maintenance bus on the basis of system, increased system development costs and fault mode.
Many problems are there is also at present to the monitoring method of TTP buses, be first can not in real time overall monitor it is whole
Total data in bus, and the data to recording be which node which time slot send can not
Show depending on changing, the insufficient increase with excessive data housekeeping of system checking is brought to later stage system development
Shortcoming.
The content of the invention
The present invention proposes a kind of time triggered agreement (TTP) bus network on-line loaded configuration and monitoring method,
The method realizes the configuration of time triggered agreement (TTP) bus network MEDL table on-line loaded and monitoring bus simultaneously,
Taking time and effort and easily malfunctioning for individually loading is solved the problems, such as in current loading method, while also will not be
Increase additional designs during system development, therefore system development costs and fault mode will not be increased, while the party
The monitoring bus that method is realized can completely monitor whole bus network, and by data corresponding node number timeslot number
Etc. showing for real-time profilingization of information, solve the problems, such as other monitoring methods, raising system is opened
Send out and verification efficiency.
