Description

A kind of equipment test verifying system based on FC network

Technical field

The utility model relates to emulation testing technical field, especially a kind of equipment test verifying system based on FC network System.

Background technique

The synthesization degree of Modern Avionics system is being continuously improved, from the discrete aviation electronics of the 1970s System arrives association type avionics system, arrives synthesis type aviation electronic, then advanced synthesis type aviation electronic system till now, Originally the communication of single node is just gradually replaced by the complex communication of multinode, and originally single communication link is just gradually unified Communication network replaced.Avionics network difference of commercial storage area network with is that it mainly operates in aviation Under the exceedingly odious environment such as space flight, for the particularity of its working environment, needed in the design of equipment and network using compared with High reliability and stability.The formulation of optical-fibre channel (FC) agreement, greatly meets the demand, and therefore, FC network is existing Using more and more extensive in the avionics system in generation.

In order to guarantee the higher reliability and stability of avionics FC network, need adequately to test target FC network With verifying.However, it is generally the case that avionics FC network include up to tens sub- EM equipment modules, as radar, electronic warfare, fire control, Navigation fusion etc., even if we build entire test macro, so many sub- EM equipment module by the way of HWIL simulation It each needs to be simulated with a FC artificial card, this scheme cost is still very high, therefore we must use other More inexpensive scheme completes the test and validation to target device.

Avionics FC network is mainly by the FC network switch and joint mechanism at as shown in Figure 1.In avionics FC network, one A node is communicated by interchanger with multiple node devices, therefore, for Mr. Yu single node equipment supplier, it is assumed that The equipment supplier, which produces N number of different node devices, has communication requirement with this N number of node device in avionics FC network Node number is M, and in order to test and verify its this N number of node device function and performance, a FC network switch is essential, The FC artificial card of analog node is further needed exist for, we can use following two semi-physical emulation platform side under normal conditions Case:

1) one piece of FC artificial card simulation of each node device communicated with the equipment

Solution principle is as shown in Figure 2.The program one opens artificial card and simulates a node device, and framework is very close to true boat Electric network, if the function of application at FC artificial card end it is powerful enough in addition can allow tested node device perceive completely less than The other side of communication, which simulates, to come.But using this scheme, there are a major defects to be that the FC artificial card needed is more, leads Cause increased costs.

2) all nodes communicated with the equipment are simulated simultaneously with one piece of FC artificial card

Solution principle is as shown in Figure 3.The feature of program maximum is only with a FC artificial card while to emulate multiple sections Point device, host where artificial card need to emulate multiple node devices, this mode solution by loading multiple node allocation plans It has determined above-mentioned cost problem.But since the data of multiple analog machines are all communicated from a link with the completion of the FC network switch, This is different with the true avionics FC network architecture first, secondly, shared link causes the data communication bandwidth of node also by very Big limitation.

Specific embodiment

With reference to the accompanying drawing, the utility model is described in detail.

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

As shown in figure 4, a kind of equipment based on FC network tests verifying system, comprising: port analog controller, test master Machine, the FC network switch and FC tester, the port analog controller have A generic port, B generic port and C generic port, here A class, B class and C class be used to distinguish different ports, the test host has FC artificial card, the FC artificial card and A class end Message number connection, A generic port only one, the A generic port is connect with C generic port signal, and C generic port has altogether in the present embodiment There are m, the C generic port is connected with FC network switch signal, and the C generic port is connect with B generic port signal, the present embodiment Middle B generic port equally has m, and the B generic port is connect with FC tester signal, and the test host and FC tester signal connect It connects.The message signale of the test of the structure is divided into network management command message and application data message.

The message signale of the test of the structure is divided into network management command message (ELS) and application data message (ASM).

Network management command message communicating (including test host is to equipment under test and equipment under test to testing two sides of host To communication):

(1) test host is to equipment under test direction: test host passes through A of the internal FC artificial card to port analog controller Generic port sends network management command message, and port analog controller is according to source address network management command message distribution to end The C generic port of mouth analog controller, C generic port share m, and the routing table of distribution is as shown in table 1, and C generic port will through interchanger Network management command message is sent to equipment under test；(2) equipment under test is to test host direction: equipment under test is through interchanger by net Network administration order message is sent to the C generic port of port analog controller, then is pooled to the A generic port hair of port analog controller Test host is given, the routing table such as table 2 of process is collected；FC network management command message communicating is in the emphasis of FC network test Hold, the communication of next step application data message can be just entered after only all meshed network interactions are normal.And in view of FC network pipe Reason command messages communication is the application layer communication protocol that belongs to established on standard FC agreement, and different clients is used by it Network management communications agreement may be different, and therefore, this part can only be completed by the FC artificial card customized, due to entire FC net Network management messages data traffic only takes up the bandwidth of very little in network, therefore multiple nodes share a FC link and not will lead to Rate-constrained.
