Train-mounted fireproof monitoring system

The invention discloses a train-mounted fireproof monitoring system. The system comprises a processing unit, a detection module, a bus driving module, an RS485 module and an RS485-to-Ethernet module. The processing unit is provided with a master control chip for data exchange and processing, the detection module is used for performing fire condition detection on a monitoring area in a train, the bus driving module is connected with the processing unit through parallel communication, the bus driving module is connected with the detection module through two buses, the processing unit and the detection module perform data information transmission and exchange through the bus driving module, the RS485 module is connected with the processing unit through serial communication, the RS485 module is used for providing an external communication interface for the processing unit, and the RS485-to-Ethernet module is connected with the RS485 module. The monitoring system can collect the train fiber condition in time by combining a train video monitoring system, and the fault report rate and the missing report rate of the train fireproof monitoring system can be reduced.
