Abstract
The invention relates to a natural gas leakage alarm system for an automobile. The natural gas leakage alarm system for the automobile is characterized in that the natural gas leakage alarm system for the automobile comprises a main alarm machine and a detector, the main alarm machine is connected with the detector, the main alarm machine is arranged on an instrument desk of the automobile, and the detector is arranged at a hazardous area, where natural gas exists, in the automobile; when the concentration of the natural gas at the hazardous area reaches a set threshold value, the detector sends out a leakage alarm signal to the main alarm machine, and the main alarm machine gives a sound-light alarm after receiving the alarm signal. Compared with the prior art, the natural gas leakage alarm system for the automobile is reliable to run and capable of improving the safety performance of natural gas automobiles.
Description
Technical field
The present invention relates to a kind of automobile safety system, especially relate to a kind of natural gas used for automobile leakage alarm system.
Background technology
Along with the development of auto industry, at present the development trend of automobile is just towards the future development of energy-saving and environmental protection, increasing new-energy automobile starts to come into the market, comprise fuel cell car, hybrid vehicle, hydrogen-powered vehicles, gas-fueled vehicles and solar telephone etc., its discharge amount of exhaust gas is lower, the development trend of load Hyundai Motor.Wherein, natural gas has become (comprising compressed natural gas and liquefied natural gas (LNG)) main flow of motor vehicle fuel, but the shortcoming of natural gas automobile is that the technological requirement of motivation package system is far away higher than conventional energy resources automobile, rock gas as power source easily leaks, and this has left hidden danger with regard to the security of giving gas-fueled vehicles.
Summary of the invention
Object of the present invention is exactly to provide a kind of natural gas used for automobile leakage alarm system that can improve gas-fueled vehicles security performance in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A kind of natural gas used for automobile leakage alarm system, comprises alarm host machine and detector, and described alarm host machine connects detector, and alarm host machine is located on the instrument desk of automobile, and detector is located at the hazardous location that has rock gas in car; In the time that the concentration of natural gas of hazardous location reaches the threshold value of setting, detector sends alerting signal to leakage alarm main frame, and alarm host machine is carried out sound and light alarm after receiving this alerting signal.
Described detector is provided with 4, is separately positioned in gas cylinder cabin, aerating panel, heat exchanger and the nacelle of automobile.
Described detector is enclosed with waterproof high molecular nanometer film.
Described alarm host machine is provided with the self-checking circuit for detection of alarm host machine and detector running status, and in the time breaking down, self-checking circuit sends failure alarm signal, is reported to the police by alarm host machine.
Described alarm host machine connects the ACC power supply of automobile, and in the time connecting ACC power supply, self-checking circuit starts automatically, carries out fault detect.
Described alarm host machine is provided with self check button, and when self check button was pressed after a period of time, self-checking circuit starts, and carries out fault detect.
Compared with prior art, the present invention has the following advantages:
One, detector of the present invention is high to the detection sensitivity of rock gas, has low-power consumption, strong interference immunity, fast response time, alarm set point is stablized and the strong feature of adaptive capacity to environment, simultaneously detector band waterproof high molecular nanometer film, waterproof, the interference of anti-other gas.
Two, easy for installation, main frame is arranged on instrument desk, small volume, and driver easily discovers.
Three, band auto-alarm function; Natural gas leaking is occurring, and the concentration that detector detects exceedes after the alarming value of setting, and detector output leakage alarm signal is to alarm host machine, and alarm host machine hummer sends chimes of doom, and corresponding red LED lamp is lighted simultaneously.After concentration of natural gas is lower than alarming value, hummer cuts out, and corresponding LED lamp reverts to green light.
Four, can adopt various ways to start the self check of system, comprise the power-on self-test while connecting automobile ACC power supply and the main frame self check of being undertaken by pressing self check button, the system that can guarantee operates in trouble-free state, improves the reliability of system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of natural gas used for automobile leakage alarm system, comprises that 1 and 4 of alarm host machine are arranged on the detector in the hazardous location that has rock gas in car, and alarm host machine 1 connects respectively each detector, alarm host machine 1 is located on the instrument desk of automobile, and driver is easily discovered.4 detectors are respectively gas cylinder cabin detector 21, aerating panel detector 22, heat exchanger detector 23 and nacelle detector 24, are arranged on respectively in gas cylinder cabin, aerating panel, heat exchanger and these hazardous locations of nacelle.
Detector of the present invention is high to the detection sensitivity of rock gas, has low-power consumption, strong interference immunity, fast response time, alarm set point is stablized and the strong feature of adaptive capacity to environment, and detector is enclosed with waterproof high molecular nanometer film simultaneously, waterproof, the interference of anti-other gas.In the time that the concentration of natural gas in any one hazardous location reaches the threshold value of setting, detector sends alerting signal to leakage alarm main frame, and alarm host machine is carried out sound and light alarm after receiving this alerting signal.
In order to guarantee system reliability of operation, alarm host machine is provided with the self-checking circuit for detection of alarm host machine and detector running status, and in the time breaking down, self-checking circuit sends failure alarm signal, is reported to the police by alarm host machine.Self-checking circuit can adopt two kinds of different Starting mode: a kind of is power-on self-test, and due to the ACC power supply of alarm host machine connection automobile, in the time connecting ACC power supply, self-checking circuit starts automatically, carries out fault detect; Another kind is main frame self check, is provided with self check button in alarm host machine, and when self check button was pressed after a period of time, self-checking circuit starts, and carries out fault detect.
