Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
When the test of the space flight carrier is realized, the related technology often carries out data transmission in a point-to-point mode, namely one test device is connected with another device to be tested through a data transmission channel, and then the data is sent to the device to be tested by the test device, so that the purpose of testing the device is realized.
However, only by means of point-to-point data transmission, the test mode is single, and if there are multiple nodes for data transmission, it is necessary to test each node, so that the test efficiency is low.
Based on this, the data transmission test system provided in this embodiment, through the manner that the relay forwarding channel of one interface board is connected with the data transmission channel of another interface board, can realize that the interface board receives the data transmission channel of the controller and forwards the test data to the data transmission channels of other interface boards through the relay forwarding channel at the same time, until the test data is transmitted to the interface board connected with the test device, thereby realizing that the layout and wiring of the test environment are more optimized, the flexibility is stronger, and the test data transmission can be more effectively realized when being adapted to more interface boards.
In this embodiment, a data transmission testing system is provided, fig. 1 is a schematic diagram of a data transmission testing system according to an embodiment of the present invention, and as shown in fig. 1, the system includes: a controller 1, at least two interface boards 2 and a test device 3.
The interface board card 2 includes: at least one data transmission channel and at least one relay forwarding channel; the data transmission channel of one interface board card 2 is connected with the relay forwarding channel of the other interface board card 2; and/or, the data transmission channel of one interface board card 2 is connected with the data transmission channel of another interface board card 2, and the relay forwarding channel of one interface board card 2 is connected with the relay forwarding channel of another interface board card, so as to construct the topology structure of the interface board card 2; the topology structure is connected with the controller 1 and the testing equipment 3 and is used for receiving the testing data sent by the controller 1 and sending the testing data to the testing equipment 3; wherein the test device 3 tests the test data to generate a test result.
Specifically, the controller 1 is configured to transmit test data to be tested. When the controller 1 sends test data, two transmission modes exist between the interface boards. The method comprises the following steps: the test data is sent to any one of the interface boards 2. After the interface board card 2 receives the test data, the test data is sent to another interface board card 2 from the relay forwarding channel. At this time, there are two cases: the interface board card 2 receiving the test data is connected with the test equipment 3, and then the test data is directly sent to the test equipment 3 for testing; if there are other interface boards 2, it is necessary to determine the interface boards 2 connected to the test device 3, and then forward the test data between the plurality of interface boards 2, so that the test data is transmitted to the interface boards 2 connected to the test device 3, and further the test device 3 tests the test data.
And two,: the data transmission channel of one interface board card 2 can be connected with the data transmission channel of the other interface board card 2, and the test data can be transmitted to the interface board card 2 connected with the test equipment 3 in a mode that the relay forwarding channel of the one interface board card 2 is connected with the relay forwarding channel of the other interface board card 2, so that the test equipment 3 tests the test data.
Alternatively, the controller 1 may be a terminal device such as a computer, a mobile phone, or the like capable of transmitting test data.
Alternatively, the interface board card 2 may be a Glink interface board card; wherein the Glink interface card may be used to characterize a high-speed transport interface card.
The data transmission test system provided by the embodiment can realize that the interface board card 2 receives the test data sent by the controller 1 and forwards the test data to the data transmission channels of other interface board cards 2 through the relay forwarding channel until the test data is transmitted to the interface board card 2 connected with the test equipment 3 when the interface board card 2 is connected with the data transmission channel of another interface board card 2 through the relay forwarding channel of one interface board card 2, so that the layout and wiring of the test environment are more optimized, the flexibility is stronger, and the test data transmission can be realized more effectively when the test data is adapted to more interface board cards 2.
It should be noted that the present invention relies on the Glink bus for the transmission of test data. Fig. 2 shows a schematic diagram of a type of data transmitted by a Glink bus. As shown in connection with FIG. 2, glink bus nodes 1 and 2 may be characterized as two interface boards 2, with the design of control flow 1-2 and big data flow 1-4 channels depending on the protocol of the interface bus (e.g., JLK1263N GLINK interface bus protocol), the chip protocol layer supporting a maximum of 2 control flow transport signals and 4 big data flow signals. Aiming at the use conditions of different test scenes, the control flow 1 transmits the periodic real-time instruction preferentially, and the control flow 2 transmits the aperiodic real-time instruction preferentially. The control flow is used for sending self-checking instructions to the image transmission system through the interface board card 2 of the Glink bus, automatically powering on, transmitting image data, inquiring state parameters, inquiring image data test results periodically, and the like. And the interface board card 2 of the GLink bus receives state parameter information, self-checking information and image data information returned by the image transmission system.
The big data stream may use at least 4 data streams simultaneously, where big data stream 1 and big data stream 2 are used for the data transmission channel and big data stream 3 and big data stream 4 are used for the relay forwarding channel (i.e., the data relay channel in fig. 2). In the test scenario, the control flow information and the big data flow information actually used are related to the specific test load data size. The control stream and the big data stream support serial or parallel transmission/reception, wherein the FIFO is used as a memory for storing test data and control instructions transmitted by the Glink bus node 1.
Fig. 3 shows a schematic structural diagram of a topology. In an alternative embodiment, as shown in fig. 3, the topology is a ring topology, and constructing the ring topology of the interface board card 2 includes: determining a first starting interface board card and a first ending interface board card from the plurality of interface board cards 2, and sequentially connecting the plurality of interface board cards 2 between the first starting interface board card and the first ending interface board card; in the adjacent interface boards 2, a data transmission channel of one interface board 2 is connected with a relay forwarding channel of another interface board 2.
Each node may be an interface board 2. The ring topology structure may include a plurality of nodes, for information exchange and transmission between multiple nodes, taking the node in fig. 3 as an example, assume that the node 1 is a test node, the node n-1 is a node to be tested, and the data of the node 1 can be forwarded by using a relay forwarding channel of a Glink protocol through a relay forwarding channel of the node 2 and the node 3; the node n can also perform relay forwarding of the relay forwarding channel, so that the node n-1 can receive the control instruction and the data information of the node 1. The topology structure scene is particularly suitable for realizing networking requirements of corresponding nodes by utilizing relay forwarding characteristics of a Glink protocol in order to further improve the coverage of a test scene after the existing Glink bus node equipment has completed a layout and wiring scene.
For ease of illustration of the connection of the ring topology in fig. 3, examples are provided below.
Each node may be considered a target object with a string and a rope, the data transmission channel may be considered a string and the relay channel may be considered a rope. When a plurality of nodes exist, the thick ropes and the thin ropes are connected between different target objects to form a ring, so that the ring topology structure is formed.
It should be noted that, the manner in which the test data is forwarded between the multiple nodes is not limited herein, and may be forwarded by repeating clockwise or counterclockwise, and the specific forwarding manner may be implemented by those skilled in the art.
Fig. 4 shows a schematic diagram of a topology. As shown in connection with fig. 4, there are 4 interface cards 2, namely 7, 8, 9 and 10 in fig. 4. The data transmission channel of the second initial interface board card (i.e. 7. Interface board card in fig. 4) is connected with the relay forwarding channel, and the data transmission channel of the second final interface board card (i.e. 10. Interface board card in fig. 4) is connected with the relay forwarding channel. 7. The interface board cards are respectively connected with the data transmission channel by adopting the data transmission channel, and the relay forwarding channel is connected with the relay forwarding channel. Wherein A, B represents data transmission channels such as 7AR, 8BT, etc. in fig. 4, C, D represents relay forwarding channels such as 7CR, 10DT, etc. The topology structure scene is particularly suitable for realizing networking requirements of corresponding nodes by utilizing relay forwarding characteristics of a Glink protocol in order to further improve the coverage of a test scene after the existing Glink bus node equipment has completed a layout and wiring scene.
Fig. 5 shows a schematic structural diagram of a topology. In an alternative embodiment, as shown in fig. 5, the topology is a hybrid ring topology, and constructing the hybrid ring topology of the interface board card 2 includes: determining a plurality of second start interface boards and a plurality of second end interface boards from the plurality of interface boards 2; sequentially connecting a plurality of second initial interface boards and a plurality of interface boards 2 between the second initial interface boards to generate a plurality of ring topology structures; and selecting a common interface board card from the plurality of ring topologies, and connecting the ring topologies through the common interface board card to generate a mixed ring topology.

Compared with a loop networking structure, the topology structure has the advantages that the test coverage is further enhanced, the number of nodes of the network is further increased, the nodes are reasonably utilized as bridging functions of a plurality of ring topologies, and the transmission function of test data among the ring topologies can be realized. Such as: loop 2 is used as a test node, loop1 is used as a node to be tested, and enters a loop 2 through self loop node 1 and node 5, then enters loop1 through node 4, then enters node 1, and finally reaches test equipment to be tested of test node 2. In the whole network, the state information and data instruction interaction of any node of the network can be inquired through the topological structure among the equipment nodes.
Fig. 6 shows a schematic structural diagram of a topology. In an alternative embodiment, as shown in connection with fig. 6, the topology is a redundant topology, the system further comprises at least two switching modules, each switching module comprising a plurality of interfaces; the interface board card 2 comprises at least two data transmission channels and/or a relay forwarding channel; the switching module is used as a relay forwarding channel, the interface board card 2 is connected with any one interface of any one switching module through any one data transmission channel or relay forwarding channel, and the other data transmission channel or relay forwarding channel is connected with the other interface of the other switching module to generate a redundant topological structure.
The system comprises at least two switching modules, namely SWITCH a and SWITCH B in fig. 6, and each switching module is provided with at least a plurality of interfaces (PORTs), wherein the interfaces can achieve the purpose of connecting the nodes with the switching modules. The topology structure is mainly suitable for the ground test application scene of a certain stage of equipment of a rocket or an aircraft, wherein the switching module can extend nodes upwards or downwards, and the nodes 5-8 are assumed to be built-in equipment, and the nodes 1-4 are assumed to be off-board equipment. The node 8 is assumed to be a device to be tested, the node 1 is assumed to be a test device 3, and compared with a ring network topology structure and a hybrid ring topology structure, the redundant topology structure is adopted to more rapidly and correspondingly control instruction and data transmission.
