Train smoke and fire alarm communication method based on independent modules combination and 3U chassis structure

摘要

The present application relates to a train smoke and fire alarm communication method based on independent modules combination and a 3U chassis structure. By externally connecting a carriage number connector X4 of an IO board to an address line to identify a carriage number, and invoking a detector configuration; acquiring temperature information and smoke concentration information by detectors and transmitting the same to a CPU board to be processed; by the CPU board, determining the acquired information, and outputting alarm information, and transmitting the alarm information to an HMI display screen in a cab; interrupting signals output between the IO board and a train safety loop, and transmitting the alarm information to the HMI display screen in the cab, and lightening a red alarm indicator on the DISP board; and by a DS board, Enet board and wireless board, collecting, storing and uploading the information.
