Embodiment Construction
[0029] Such as figure 1 Shown is the network topology diagram of the system of the present invention, and its realization principle is exactly that vehicle control module 5 realizes the data communication between man-machine interface 2 (also called man-machine interface or HMI) and incident recorder 1 through MVB bus 4, thereby will The download operation instruction performed by the maintenance personnel on the man-machine interface 2 is forwarded to the event recorder 1, and the relevant download status information fed back by the event recorder 1 is sent to the man-machine interface 2 for display. The event recorder 1 can also directly read the sending port data of the man-machine interface 2, and the man-machine interface 2 can also directly read the sending port data of the event recorder 1. But generally all transfer through the vehicle control module 5 .
[0030] The data visual download control system based on the network embedded system of the present invention comp...
