Description
Technical field
The invention belongs to synthetic aviation electronic system application field, and present invention relates particularly to a kind of software of avionics system
Loading method.
Background technology
With the continuous improvement of avlomcs system integration degree, avionics system software size is increasingly huge, comprehensive
Combination avionics system is undoubtedly software intensive system, the dependence of the realization of each subsystem function of aviation electronics to software
It is increasing, in order to which the software in subsystems is upgraded and safeguarded in time, it is necessary to which external system is constantly inside
The a variety of software datas of portion's system loads, to meet continually changing system requirements.Existing external system is internally
Load mode of uniting is loaded using serial ports more, although disclosure satisfy that loading functional requirement, following defect also be present：
1st, external system needs one by one each node loading software data in internally system, it is necessary to which artificial intervention selects
Different nodes, it is time-consuming, error-prone；
2nd, external system and built-in system use conventional serial interface load mode, for large batch of data in loading speed
It can not meet to require；
3rd, serial data loading no parity check mechanism, security are relatively low.
The content of the invention
In order to solve the defects of pointed in background technology, the present invention carries a kind of method for loading software of avionics system, should
Method introduces first nodes can quickly, quickly and easily realize difference of the external system internally in system by batch processing mode
The software data loading of node, save loading procedure artificially selects to need to load node the step of.
The technical solution of the present invention：
A kind of method for loading software of avionics system, it is characterized in that：Comprise the following steps：
1】Internally system divides the node of two ranks, highest-ranking to be defined as first nodes, and rank time is high to determine
Justice is two-level node, and data sharing memory block is provided with the first nodes；
2】Shaken hands between first nodes in external data loader and built-in system by synch command,
If success is shaken hands, into step 3】；If it fails, exit current sessions；
3】The software data loaded according to needed for user's needs in outside data loader end selection built-in system interior joint,
Form autoexec；The autoexec have recorded source of each software data in first nodes data sharing memory block
Address, each software data need the target two-level node number being loaded into and each software data to be loaded into the target two level section
Destination address on point；
4】External data loader parses autoexec, the software data that the needs described in autoexec are loaded
It is loaded into the data sharing memory block of first nodes；
5】User operates external data loader and sends autoexec to first nodes, and first nodes receive batch processing text
After part, parsing loads the autoexec, draws load information, and the load information includes each software data in first nodes
Source address, each software data in data sharing memory block need the target two-level node number being loaded into and each software number
According to the destination address being loaded on the target two-level node；
6】First nodes form loading command, send loading command to two-level node according to load information；
7】After two-level node receives the loading command of first nodes, the information in loading command, out of first nodes
Data sharing memory block, which obtains, to be needed to load the software data to two-level node, and the software data got is cured into two level
In the destination address of node；
8】Stress state information is returned to first nodes by two-level node；
9】First nodes, which collect the stress state information of whole built-in system first nodes and two-level node, to be returned to outside
Portion's data loader, loading procedure terminate.
Communicated between the first nodes and two-level node of above-mentioned built-in system by Doorbell.
The first nodes and external data loader of above-mentioned built-in system are communicated by industry ethernet, first nodes and two
Pass through VME bus communications between level node.
Advantage for present invention：
1st, the present invention loads batch processing by introducing autoexec, first nodes in software loading process by parsing
Carry out data loading of the file to two-level node, reduces the manual intervention of user, improves loading efficiency.
2nd, the present invention enters line command by Doorbell between first nodes and two-level node and sends and respond, it is ensured that life
Make the real-time of interaction.
3rd, the present invention sets data sharing memory block, first nodes and two-level node to pass through shared storage in first nodes
Mechanism carries out data sharing, avoids the multistage copy of data, improves the efficiency of data communication.
4th, the first nodes of external data loader of the invention and built-in system are led to using Transmission Control Protocol Ethernet
News, ensure that data transfer is functions reliably and efficiently between first nodes and external load device.
Brief description of the drawings
Fig. 1 is a kind of example structure figure of the present invention；
Fig. 2 is first nodes loading procedure state diagram；
Fig. 3 is the loading flow chart of two-level node.
Embodiment
Modules node under this method is divided into first nodes and two level section according to role's difference in system loads
Point.
First nodes are in core status in whole system loading, are handed over by entering row information with external data loader
Mutually, from external data loader obtain system loads need data and support information, meanwhile, first nodes by and two level
Node carries out information exchange, and notice two-level node reads the data for needing to load from data sharing memory block.
Two-level node lays under tribute in whole system loading, by carrying out information exchange with first nodes, from number
The software data for needing to load is obtained according to shared memory, and software data is cured to the specified location of two-level node.
For a kind of example structure figure as shown in Figure 1, first nodes and external data loader pass through ether in this method
Network bus communicates, and passes through VME bus communications between first nodes and two-level node.
First nodes are communicated by Ethernet interface with the loading tool on external node, the order to loading tool
Parsed, loading data and loading autoexec are obtained from loading tool, while loading procedure is returned to loading tool
State.Loading autoexec in have recorded data loading destination node and destination address, first nodes from loading batch processing
After the information is parsed in file, according to corresponding to being organized into the source address and destination address information of destination node numbering and data
Loading command, the loading command is sent to two-level node, two-level node is parsed after receiving loading command, is ordered according to loading
The source address specified and data length are made, the software data is read from data sharing memory block to two-level node, according to loading
The destination address specified in order, the software data is cured on specified address.After the completion of solidification, to first nodes by answering
Answer bag and return to implementing result.The loading procedure state diagram of first nodes and the loading flow chart of two-level node are shown in Fig. 2 and figure respectively
