Embodiment Construction
[0040] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0041] In order to solve the problems of the prior art, the present invention provides a data recording and playback method based on Ethernet and SRIO, and the data recording and playback method is implemented based on a data recording and playback device, such as figure 1 As shown, the data recording and playback device includes: an upper layer module, an interface module and a storage module;
[0042] Said method comprises the following steps in recording mode:
[0043] Step 11: start recording;
[0044] The upper layer module sends a start record command to the interface module, and the interface module forwards the command to the storage module after receiving the command; the storage module sends a return order t...

The invention belongs to the technical field of computer network communication, and specifically relates to a data recording and playback method based on Ethernet and SRIO, which is implemented based on a data recording and playback device, and the device includes: an upper layer module, an interface module and a storage module; the method The data recording and playback device based on it adopts VPX architecture, which is divided into two modes: recording and playback. In the record mode, it can receive and store CAN, CameraLink, ARINC, and USB bus data, and display CameraLink images in real time; in the playback mode, CAN, CameraLink, ARINC, and USB data can be uploaded to the upper device for user use. By adopting the design strategy of power failure protection and partition storage, the integrity and reliability of data are improved; the addition of real-time pre-display function improves user experience.
Description
technical field [0001] The invention belongs to the technical field of computer network communication, and in particular relates to a data recording and playback method based on Ethernet and SRIO. Background technique [0002] With the development of troubleshooting and data analysis technology, data recording and playback equipment is widely used. In a certain practical application environment, it is necessary to record and store CAN, CameraLink, ARINC, and USB bus data, and display the received CameraLink image in real time. Traditional devices only have recording and storage functions. When the system suddenly loses power, it is easy to cause loss of online data; when there are many types of received data, there will be confusion of stored data; when users have visualization needs, real-time display cannot be achieved. These problems will affect the integrity of the data and user experience. Contents of the invention [0003] (1) Technical problems to be solved [0...
