Specific embodiment
With reference to shown in Fig. 1 to Fig. 3, the present invention is described in further detail.
As shown in Fig. 2 present embodiment discloses a kind of exploitation of CAN and method of testing, the method comprises the following steps
S1 to S3：
Application software needed for S1, actual CAN data Commissioning Analysis sends number to the network service that virtual CAN is created
According to；
Wherein, the application software needed for actual CAN data Commissioning Analysis includes needing application software, the packet capturing of exploitation debugging
The application software such as instrument, real-time data analysis instrument and data implantation tool.It should be noted that not limited in the present embodiment
The type and quantity of application software, the need for art technology can be according to actual conditions, select different application software.
Needed for the data forwarding that S2, the network service will be received to connected other CAN Commissioning Analysis
Application software, and the data forwarding that will be received is to actual CAN；
S3, using the application software needed for the CAN Commissioning Analysis being connected with the network service to the network service turn
The data of hair carry out Commissioning Analysis.
In actual applications, the data for disturbing bag to disturb actual CAN are injected by data implantation tool, in interference
During, gripping tool is captured to the communication data between individual application software and actual CAN, and by other application software
Communication data to capturing carries out Commissioning Analysis.Communication process in the present embodiment between application software and actual CAN is：
The other application that the data of a certain application software are forwarded directly to its connection by the network service created by virtual CAN is soft
Part, multiple application software can realize data transmit-receive by network service with using an actual CAN.And traditional communication
Mode is that each application software needs to be communicated with the equipment in actual CAN by corresponding USB-CAN, realizes number
According to transmitting-receiving, that is, need to connect multiple USB-CAN on one computer.Therefore, it is of the invention compared with traditional communication mode, only
Needing one even can not need USB-CAN, greatly reduce the quantity of USB-CAN, reduce the complexity of whole system
And use cost.
In addition, it should be noted that, the data of the actual CAN in the present embodiment to capturing carry out the mistake of Commissioning Analysis
Journey is identical with existing Commissioning Analysis process, is repeated no more in the present embodiment.
Further, it is necessary to explanation, the data forwarding that the application software that network service will be received sends to actual CAN
After bus, actual CAN is transmitted data in connected equipment, and equipment performs corresponding dynamic according to the data for receiving
Make or return corresponding message data.When equipment returns to corresponding message data, the CAN number disclosed in the present embodiment
Also comprise the following steps according to adjustment method：
The data that the network service will be received are forwarded to actual CAN by USB-CAN, and receive actual CAN
The message data of return；
The message data that actual CAN is returned is forwarded to the network service CAN being connected with the network service
In application software needed for Commissioning Analysis；
Wherein, the message data that described actual CAN is returned is the message number that the equipment being connected with actual CAN is produced
