Modularized high speed motor train unit smoke and fire online monitoring system

Abstract

The invention relates to a modular high-speed EMU pyrotechnic online monitoring system, which includes a pyrotechnic display system and multiple single-vehicle network monitoring systems, and multiple single-vehicle network monitoring systems are connected through a dual-way redundant train RS485 network; each single-vehicle network The monitoring system includes a PSSIG power supply module for power distribution of the system, an FSK loop module with two FSK interfaces, two RS485 relay modules and multiple smoke detectors. The signals sent by the FSK loop module and the pyrotechnic display system are passed through The RS485 relay module reaches the car controller; the FSK loop module is connected in series with multiple smoke detectors through two FSK interfaces to form a loop bus. The invention adopts a modular design, the modules are independent of each other and can be replaced separately; the two redundant train networks are independently designed without interfering with each other, and the online monitoring function of the system can be completed only if one line is online; the power line and signal line of the smoke detector Public, no need to lay separate communication cables.

Description

technical field [0001] The invention relates to the technical field of fire monitoring of rail vehicles, in particular to an on-line monitoring system for pyrotechnics of a modular high-speed train set. Background technique [0002] The high-speed EMU is a highly integrated manned tool with the characteristics of fast movement speed and complex structure. The electrical equipment of high-speed EMUs is various and the space is airtight. Once a fire breaks out, if it is not found in time, it is difficult to take corresponding measures in time, which will cause greater casualties and property losses. Therefore, it is of great significance to invent a safe and reliable high-speed EMU pyrotechnics online monitoring system. [0003] Although the traditional fire alarm system can realize fire alarm work, it still has the following deficiencies: [0004] (1) In terms of structure, except for the smoke detector, other components of the fire alarm system are integrated into one, whi...
