Embodiment 1

[0027] An automatic fire-extinguishing and explosion-suppression system for public transport vehicles, which at least comprises: a nozzle 2, a fire-extinguishing bottle 3, a control box 4 and an acousto-optic alarm 5, wherein the fire-extinguishing bottle 3 is communicated with a plurality of nozzles 2 through a pipeline 1 to extinguish the fire. The bottle 3 and the sound and light alarm 5 are respectively electrically connected with the control box 4; the control box 4 is electrically connected with a plurality of detectors 8 through the internal CAN bus 7.

Embodiment 2

[0029] On the basis of Example 1, as figure 1As shown in the figure, an automatic fire-extinguishing and explosion-suppression system for public transport vehicles at least includes: a nozzle 2, a fire-extinguishing bottle 3, a control box 4 and an acousto-optic alarm 5. The fire-extinguishing bottle 3 passes through a pipeline 1 and six nozzles 2 The fire extinguishing bottle 3 and the sound and light alarm 5 are respectively electrically connected with the control box 4; the control box 4 is electrically connected with the five detectors through the internal CAN bus 7. The five detectors and the six nozzles 2 are spaced apart; the detectors are purple-infrared flame detectors; the fire extinguishing agent used in the fire extinguishing bottle 3 is hexafluoropropane fire extinguishing agent. The density of hexafluoropropane (HFC-236) fire extinguishing agent is 5 times that of air. After spraying, it will be suspended at the bottom of the car and should not be lost from the w...

Embodiment 3

[0031] On the basis of Embodiment 2, the control box 4 acts as the logical control core of the whole system, such as figure 2 As shown, the control box 4 is composed of a power supply circuit 13, a single-chip microcomputer 14, a fire extinguishing bottle drive circuit 17, an inner CAN interface 12, an outer CAN interface 16 and a display unit 15. The single-chip microcomputer 14 passes through the inner CAN interface 12. The external CAN interface 16 is electrically connected with the internal CAN bus 7 and the external CAN bus 6 respectively; the single chip microcomputer 14 is also electrically connected with the fire extinguishing bottle driving circuit 17 and the display unit 15 respectively; The emergency button 11 ; the single-chip microcomputer 14 , the display unit 15 and the fire extinguishing bottle drive circuit 17 are all electrically connected to the power supply circuit 13 .

[0032] The power supply circuit 13 is a DC / DC power supply module; the single-chip mi...

Abstract

The invention relates to an automatic firefighting explosion-prevention system and method for a bus. The automatic firefighting explosion-prevention system is characterized by at least comprising nozzles, a firefighting bottle, a control box and an audible and visual alarm, wherein the firefighting bottle is communicated with a plurality of nozzles through pipelines; the firefighting bottle and the audible and visual alarm are electrically connected with the control box respectively; the control box is electrically connected with a plurality of detectors through internal CAN buses. Due to the adoption of the whole system, monitoring on fire hazard or explosion in a whole carriage can be achieved, a fire extinguishing agent can be sprayed into the whole carriage in all directions, automatic alarm and automatic firefighting bottle driving can be achieved, and the rapid fire fighting and explosion prevention properties of the bus can be effectively improved.

Description

technical field [0001] The present invention relates to a fire alarm system of public transport vehicles, in particular to an automatic fire extinguishing and explosion suppression system and method for public transport vehicles. It belongs to the field of fire alarm and automatic fire extinguishing of public transportation. Background technique [0002] In order to reduce air pollution caused by vehicle exhaust and alleviate road congestion during urban peak hours, the state advocates green travel for citizens, and continuously develops and improves the urban public transport system, making buses a densely populated place, and it is also a need for public safety. monitoring site. In recent years, the domestic anti-terrorism situation has become increasingly severe. There are more and more typical threats such as arson and improvised explosives in public transport vehicles. Mass casualties and injuries occur frequently, resulting in serious adverse consequences, bringing pa...
