The present invention is further illustrated by the following preferred embodiments, but is not intended to be limited thereby.
The embodiment provides a DCS system signal flow configuration module, which includes an intra-chassis backplane communication network module 201, an intra-chassis signal configuration module 202, an inter-chassis signal configuration module 203, and a communication packing module 204.
The backplane communication network module 201 in the case is used for connecting the MPU, the IOU, the CMU, and the CMUE of the DCS system. Referring to FIG. 2, the backplane communication network module 201 includes LVDS-A, LVDS-B, LVDS-C, LVDS-D. LVDS-A is used for the IOU and MPU communication in the group; LVDS-B and LVDS-C form a redundant network, and the redundant network is used for communication between the MPU and the CMU; LVDS-D is used for communication between the CMU and the CMUE.
The signals are divided into two categories, namely safe signals and non-safe signals, the safe signals pass through a safe channel, and the non-safe signals pass through a non-safe channel.
The in-chassis signal configuration module 202 is configured to obtain a path of the in-chassis signal and a physical location of the in-chassis signal according to a source address of the in-chassis signal, a destination address of the in-chassis signal, and a security type of the in-chassis signal. The chassis signal configuration module 202 obtains a first target communication path and a first target communication buffer based on the backplane communication routing table. The communication packing module 204 is configured to pack and send the signal of the first target communication buffer according to the first target communication path.

The inter-chassis signal configuration module 203 obtains a second target communication path and a second target communication buffer according to the user requirement. The chassis-to-chassis signal configuration module 203 is configured according to user requirements, rather than a fixed backplane communication network. The path calculation cannot be performed by means of routing. The inter-chassis signal configuration module 203 provides a communication path (a second target communication path) according to a source address (a transmission start point), a destination address (a transmission end point), a channel type (a security type), and a communication network input of the inter-chassis signal, and specifies a communication buffer (a second target communication buffer).
