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...
