The beneficial effects of the utility model are: the utility model, once energising, without any operation, just enters monitor state automatically.During Normal Alarm main control system send drip, drip, drip between continuous cry, the alarm lamp of relevant position is glittering, illustrates that the position gas concentration corresponding to this gas sensor place exceeds standard.In the inner open circuit of the loose contact of gas sensor connecting line or gas sensor, short circuit, main control system send dichloro-diphenyl-dichlorothane--dichloro-diphenyl-dichlorothane interrupted cry, meanwhile, the alarm lamp of relevant position is glittering, and showing has fault corresponding to the gas sensor of this alarm lamp.If automobile is disturbed and caused reporting to the police by ambient atmos, after confirming that Fei Benche leaks, press reset button and can force to close down main control system 1 minute.In at this moment, can make vehicle break away from scene, if report to the police, not remove, after 1 minute, main control system is controlled closed electromagnetic valve, cuts off gas supply.Have alert fast response time, sensitivity is good, and the feature of strong interference immunity all can be sent alerting signal at storage battery during under-voltage or overvoltage.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model;
Fig. 2 is the structural drawing of gas sensor described in the utility model.
In figure: 1-main control system, 2-is under-voltage over-pressure safety device, 3-gas sensor, 4-solenoid valve, 5-display panel, 31-sensor body, 32-grate opening, 33-mounting clamp, 34-waterproof jacket.
Embodiment
For making that the utility model is done further to understand, below with reference to Figure of description and specific embodiment, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of gas vehicle gas leakage alarm, comprises main control system 1, solenoid valve 4 and some gas sensors 3.Each gas sensor 3 is connected with main control system 1 by the corresponding input port on main control system 1 respectively, it is for the concentration of detection sensor combustion gas environment inside car rock gas, at detection sensor in combustion gas environment inside car during the paranormal safe concentration value of concentration of natural gas, gas sensor 3 produces induced signal, and induced signal is transferred to main control system 1.Described solenoid valve 4 is located on the outlet pipe of fuel gas bottle, and is connected with described main control system 1 by signal wire.At gas sensor 3 detection sensors in combustion gas environment inside car during the paranormal safe concentration value of concentration of natural gas, the signal that gas sensor 3 produces induction is transferred to main control system 1, then main control system 1 is processed and is sent valve shutoff executive signal to solenoid valve 4 through signal, make solenoid valve 4 carry out valve and turn-off action, fuel gas bottle is closed.
Further, described main control system 1 is provided with a display panel 5, and this display panel 5 is provided with reset button, noise elimination button and corresponding to the alarm lamp of each gas sensor 3.At automobile, be subject to ambient atmos and disturb, as the tail gas of other vehicles or just in aerating, during the warning that causes, after confirming Fei Benche natural gas leaking, press this reset button, make main control system 1 quit work 1 minute.In at this moment, can make vehicle break away from scene, if report to the police, not remove, after 1 minute, main control system 1 again sends valve to solenoid valve 4 and turn-offs executive signal, makes solenoid valve 4 carry out valve and turn-offs action, and fuel gas bottle is closed.When gas sensor 3 continues to report to the police because of the inner open circuit of connecting line loose contact or gas sensor 3, the short alarm causing, by pressing noise elimination button, can be forced shutdown loudspeaker.In order to be unlikely, affect the detection of the gas leakage of alarm, in the situation that reporting to the police not releasing, main control system 1 is automatic recovery warning function after 5 minutes, starts loudspeaker and continues to send alarm sound.In order further to prevent causing fault because of automobile storage battery voltage instability; affect use sensitivity of the present utility model and response speed; main control system 1 is connected with a under-voltage over-pressure safety device 2 detecting for automobile storage battery being carried out to under-voltage detection and overvoltage; this is under-voltage, and over-pressure safety device 2 can be made corresponding voltage compensation when automobile storage battery voltage instability, to maintain burning voltage.For saving the equipment occupation space of alarm, in main control system 1, be integrated with the loudspeaker for sounding the alarm.Malfunctioning for preventing that gas sensor 3 from use making moist, gas sensor 3 is arranged with waterproof jacket 34 at the terminals of its sensor body 31, for ease of gas sensor 3 being fixed on to each pipeline location in gas vehicle, waterproof jacket 34 is provided with mounting clamp 33, by this mounting clamp 33, can easily gas sensor 3 be fixed.
In sum, the utility model, once energising, without any operation, just enters monitor state automatically.During Normal Alarm main control system send drip, drip, drip between continuous cry, the alarm lamp of relevant position is glittering, illustrates that the position gas concentration corresponding to this gas sensor place exceeds standard.In the inner open circuit of the loose contact of gas sensor connecting line or gas sensor, short circuit, main control system send dichloro-diphenyl-dichlorothane--dichloro-diphenyl-dichlorothane interrupted cry, meanwhile, the alarm lamp of relevant position is glittering, and showing has fault corresponding to the gas sensor of this alarm lamp.If automobile is disturbed and caused reporting to the police by ambient atmos, after confirming that Fei Benche leaks, press reset button and can force to close down main control system 1 minute.In at this moment, can make vehicle break away from scene, if report to the police, not remove, after 1 minute, main control system is controlled closed electromagnetic valve, cuts off gas supply.Have alert fast response time, sensitivity is good, and the feature of strong interference immunity all can be sent alerting signal at storage battery during under-voltage or overvoltage.
