A bus array combustible detection and early warning control system

Abstract

The invention provides an array type inflammable detecting and early warning control system for a bus. The system comprises a warming control host computer, a plurality of linear array type volatilizable inflammable detectors, a detector connecting bus and a spraying system; a combustible gas sensor and an MCU (Microprogrammed Control Unit) microprocessor are arranged in each liner array type volatilizable inflammable detector; the plurality of linear array type volatilizable inflammable detectors form a sensing array; the combustible gas sensors are used for transmitting the detected concentration value to the MCU microprocessors to be converted into a digital signal, and then the digital signal is sent to the warning control host; the warning control host is used for outputting a spraying firefighting control signal according to the specific danger level. With the adoption of the system, the components of combustible gas volatiled to the air can be detected after or during the inflammable is discharged, then the early warning can be performed timely before the minimum seconds that the inflammable is ignited, and therefore, the time for stopping and opening the door is obtained for a driver; the driver can control the spraying system to spray before the inflammable is ignited, so as to prevent passengers from being juried by man-made fire or fire caused by accident, and as a result, the possible troubles can be prevented really.

Description

technical field [0001] The invention relates to a traffic safety early warning control system, in particular to a bus array type combustible detection early warning control system. Background technique [0002] Vicious fire accidents caused by intentional arson on public vehicles and leakage of inflammable materials carried by passengers have seriously threatened the lives and property of passengers. Currently, the portable fire extinguishers equipped in buses are too late to deal with such fires. For this hidden danger, although some public transport vehicles are equipped with automatic sprinkler systems, they must be activated by human judgment after the fire breaks out. It takes at least ten to tens of seconds to finally extinguish the fire. Since the passenger density in the bus may be very high, passengers cannot escape the fire source urgently, and ten seconds is enough to cause serious injury to the passengers in the fire source.

[0002] Vicious fire accidents caused by intentional arson on public vehicles and leakage of inflammable materials carried by passengers have seriously threatened the lives and property of passengers. Currently, the portable fire extinguishers equipped in buses are too late to deal with such fires. For this hidden danger, although some public transport vehicles are equipped with automatic sprinkler systems, they must be activated by human judgment after the fire breaks out. It takes at least ten to tens of seconds to finally extinguish the fire. Since the passenger density in the bus may be high, passengers cannot escape the fire source urgently, and ten seconds is enough to cause serious injury to the passengers inside the fire source.

[0003] The automatic fire extinguishing system of the existing bus is started by human control after a fire breaks out. This type of fire spreads quickly, the fire is violent, and the density of people in the bus is high, so it is impossible to avoid the fire in time. Therefore, a few seconds of the fire is enough to cause serious injury to the passengers in the bus, especially near the fire point.

[0004] In the bus, if the inflammables carried by passengers are leaked or deliberately set on fire, they must go through the process of pouring out (or leaking) to form a kindling and igniting the inflammables (such as gasoline, alcohol, etc.). For more than a few seconds, the automatic fire extinguishing system in the prior art cannot detect the combustible gas components volatilized into the air after the combustibles are poured out or when they are poured out, and cannot do it in the shortest few seconds before the combustibles are ignited. Early warning, not prevention in the bud
