Example two
Referring to fig. 3, a multi-network-segment gateway routing test device based on hardware-in-loop equipment provided by the embodiment of the invention mainly comprises an HIL (hardware-in-loop) cabinet, a CAN board card, a CAN model, an HIL host computer, a tested gateway and the like.
The CAN model is responsible for simulating a message needing to be routed by a sending gateway and receiving the message forwarded by the gateway; then through CAN board card; the CAN board card is responsible for carrying out physical CAN communication with the gateway, sending the message sent by the CAN model enable to the gateway, and simultaneously receiving the message sent by the gateway and transmitting the message to the CAN model. The CAN board card provided by the company dSPACE of the HIL cabinet supplier has the high-speed simulation function, and the provided automatic test software has the characteristics of simple and convenient operation, modularization of automatic sequence development and high-speed operation response, and CAN realize the ms-level quick operation response when the automatic test is carried out.
In one embodiment of the present invention, by performing gateway detection on the device shown in fig. 3, the message X is first sent by the controller B on the CAN1 segment, and the controller B on the CAN2 segment 2 needs to receive the message, and then the gateway is required to route the message X from the CAN1 to the CAN2. And signals such as signal-1, signal-2, signal-3 and … signal-n are defined in message X. In the test of message routing completion, signal values of signal-1, signal-2, signal-3- … signal-n need to be set (suggested to be respectively set to a maximum value, a minimum value and any intermediate value) in CAN1, then signal-1, signal-2, signal-3- … signal-n signals of message X are monitored in CAN2 and compared with values in CAN1, and the corresponding signals CAN be considered successful when the signal values are equal and sent out in a fixed period. In the test system described above, the signal modules of the response CAN be generated in the matlb/simulink by means of the established CANdbc file, which are generated for example by the above-mentioned signal-1, signal-2, signal-3 … signal-n, CAN1 and CAN2. During testing, the values of signal-1, signal-2 and signal-3 … in CAN1 are respectively defined as a, b and c … n, and are sent according to a period of 100 ms; and then monitoring the message X in the CAN2, and judging that the test is qualified when the message X on the CAN2 is also sent in a period of 100ms and the signal-1, signal-2 and signal-3- … signal-n values are also a, b and c … n.
The step of generating the simulink message signal module is shown in fig. 4, in which the dbc file is imported into CAN configuration software (provided by dstoce and operated in the simulink environment), and the signal module CAN be generated by the configuration of the CAN configuration software. Each message signal may generate a constant module in the simulink that may be set to a desired value by a write module of the automated test software. In the test system, for a message to be routed, a source network segment and a target network segment are required to generate consistent signal modules in a simulink, and the signal modules are mainly used for writing values and reading values.

In the test process, after signal-1, signal-2, signal-3 and signal-n signal modules in the CAN1 simulation model are assigned, corresponding signal values of a CAN1 message X are written into a set value, and then the set value is transmitted to a gateway through a CAN1 bus which is physically connected with the gateway through a CAN board card; after receiving the message X of the CAN1, the gateway CAN route the message X to the CAN2 according to the gateway, the CAN2 bus physically connected with the CAN board card at the gateway is transmitted to the HIL board card, then the simulink model CAN analyze the routed message X according to the dbc file, and then the signal-1, the signal-2, the signal-3 and the signal-n signal modules in the CAN2 simulation model CAN read the true value in the routed message X, and then the real value is compared with the original set value, so that whether the test result is qualified CAN be confirmed.
In the above embodiment, as shown in fig. 5, a schematic diagram of assigning and reading a message signal value is provided for the present embodiment, a write module of DSPACE system automation test software writes signal-1, signal-2, signal-3- … signal-n signal modules of a CAN model X message of a CAN1 network segment into a test value (a, b, c, n), and then sends the test value to a gateway through a CAN line, and then the gateway routes the X message to CAN2; and then, waiting for 100ms (namely, the sending period of the message X) through the wait module in a delay way, reading out the values of the signal-1, signal-2 and signal-3 … signal-n signals of the message X of the CAN2 network segment through the read module of the automatic test software, comparing and judging with the written value (a, b, c, n), and considering that the message routing function passes when the value of the signal CAN2 is equal to the value of the signal CAN 1.
The foregoing embodiments have been provided for the purpose of illustrating the general principles of the present invention, and are not to be construed as limiting the scope of the invention. It should be noted that any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art without departing from the spirit and principles of the present invention are intended to be included in the scope of the present invention.
