Embodiment
Vehicle management computer is in the main controlled node of network configuration, and it realizes ordering and information interaction by system bus (CC) and other network nodes, realizes the information interaction with other VMC by CCDL bus.After CC bus obtains data message, need to identify whether the data obtained are autonomous forwarding information, when needing to forward, CC bus directly can send information to CCDL bus by the forwarding interface residing in FPGA, and do not need main process to forward, CCDL bus is by polling dispatching, and the transmission message of host processor module and the message time-sharing send of CC forwarding are to other VMC in the future.
The crosslinked model of autonomous forwarding as shown in Figure 2.Wherein the number of remaining passage and the procotol of bus according to system requirements configuration and can be chosen.
In this design architecture, CC bus loads allocation list those message known by power-up initializing to be needed independently to forward, and does not rely on primary processor operating state, even if main processor modules is damaged, CC bus still can picks up data, can not lose the ability of shared resource.
1, based on the enforcement of 1394 protocol bus
CCDL bus adopts 1394 protocol realization, speed S400, long transmission distance, and this universal serial bus is that the application of high-speed transfer provides very large potential, can meet the bandwidth requirement that Aircraft Management Computer system of new generation increases day by day.
This part realizes primarily of FPGA, link layer chip TSB12LV32-EP and physical chip TSB41BA3B-EP, FPGA mainly realize initialization, each chip sequencing control and independently forward scheduling, link layer chip realizes transport layer protocol, and physical chip realizes the connection of electrical characteristic, it realizes functional block diagram as shown in Figure 3.
2, based on 1394 universal serial bus redundance Cross transfer topological structures
CCDL realizes the data cross transmission between each VMC, in order to eliminate interchannel impact, prevents fault from spreading, and CCDL design adopts point-to-point mode, is explained here, as shown in Figure 3 with four remaining topological structures.
The CCDL of every platform VMC adopts 4 1394 buses, comprises 1 and sends bus, and 3 receive bus, every bar bus supporting rate 400Mbps, CCDL sending node is forced to be configured to root node, and its agreement meets IEEE-1394B specification, asynchronous flow bag is adopted to carry out transfer of data, support hardware CRC check.
3, independently enforcement is forwarded
Autonomous forwarding realizes the asynchronous transmission of message by FIFO, its memory bank is provided by CCDL-FPGA internal resource, not plug-in independent FIFO, CC-FPGA realizes the reception of CC bus and the autonomous filling forwarding FIFO, CCDL-FPGA realizes the reading of filling FIFO by polling mode, in time the message independently forwarded is sent to the Aircraft Management Computer VMC of other remainings by CCDL bus.Its structure as shown in Figure 4.
The concrete handling process of autonomous CCDL forwarding messages is as follows:
Step 1: in power up, automatically load the content of separate configurations information FLASH, the content according to allocation list carries out message index;
Step 2: nodes receive messages module, after No. ID that receives message, obtains this message the need of forwarding by inquire-receive allocation list;
Step 2.1: if need the message forwarded, after then waiting until that receipt message completes, CRC check correct (when CRC check is made mistakes, directly abandoning this message), the autonomous forwarding of node receiver module notice has Messages-Waiting to forward, and this message is put into the outer corresponding DPRAM1 of sheet simultaneously;
Step 2.2: if not forwarding messages, then, after waiting until that receipt message completes, put into the outer DPRAM1 of sheet, do not forward;
Step 3: the autonomous forwarding notice of three nodes is dispatched in the training in rotation of autonomous forwarding control module, when training in rotation has to certain node the message needing to forward, read the buffering area of this node, obtain the asynchronous flow bag needing to forward, and add two packet header word 0x5A5A5A5A, 0xA5A5A5A5 and two bag tail words 0xA5A5A5A5,0x5A5A5A5A;
Step 4: by the autonomous forwarding fifo interface between bus node module and CCDL node module, this packet is inserted in the forwarding FIFO of CCDL node module, waits for that CCDL node module sends;
Step 5:CCDL node module inquires and forwards FIFO non-NULL, from this FIFO, then take out data is sent on other remaining VMC by 1394 buses, this computer also can be obtained other VMC and be forwarded the message come by CCDL, and these data is put in the outer DPRAM2 of sheet;
Step 6: remaining passage is by comparing the data of DPRAM1 and DPRAM2, determine the correctness of multiplicated system signal transacting, if result normally, is for further processing, otherwise discovery fault, then multiple computer is by carrying out failure diagnosis and fault location than monitoring and voting mutually, determine faulty computer, and it is excised.
4, configurable autonomous forwarding information
In the present invention, autonomous forwarding information is specified by special configuration information memory FLASH, and this config memory can arrange the message label that user need forward.
Fpga logic selects the position of corresponding configuration table to start to carry allocation list header according to model number and No. ID, LRU, when initialization, bus control unit node (CC) must verify the information that configuration information memory stores, and check result is noticed CC node host application program, this process does not rely on the intervention of host application, and the loading of allocation list has been loaded in power up automatically by hardware.
After this allocation list reads, receipt message configuring area responsible node all should receipt message receiving scheduling configuration, whether the order receiving message according to node is carried out index and is autonomous forwarding messages according to about location differentiates in receipt message control word structure, see table 1.
Table 1 32 receipt message control word structures
Specific information config memory FLASH (GSE signal is ' 0 ') could can only upgrade under specific ground environment, this object prevents from changing arbitrarily under airborne circumstance, allocation list can carry out message agreement according to the different demand of system application simultaneously, the independence of allocation list uses and provides conveniently for user's subsequent upgrade and CCDL forward the flexibility configured, stop software to upgrade on a large scale change, simplify configuration item management.
