Abstract
The invention relates to the technical field of natural gas detection devices, and in particular relates to a vehicular natural gas detection device; a vehicular gas leakage alarm device comprises a controller; the controller is connected to a signal indication alarm, a natural gas sensor and a temperature sensor; the signal indication alarm is installed on an instrument panel; and the signal indication alarm comprises an indication lamp and a buzzer. The vehicular natural gas detection device disclosed by the invention has the benefits that the vehicular natural gas detection device is specially used for detecting natural gas and alarming gas leakage of a natural gas truck and can be installed at different positions in the truck; if gas is leaked, an alarm signal can be prompted to a host on a workbench; the host correspondingly alarms and indicates a gas leakage position, so that potential safety hazards are processed in time; and the security coefficient is high. Gas leakage alarms are mainly divided into two major kinds including LNG (Liquefied Natural Gas) and CNG (Compressed Natural Gas) gas leakage alarms. The vehicular natural gas detection device is used for detecting and alarming liquefied gas leakage on a liquefied gas bus, and simultaneously detecting and displaying the temperature of an engine compartment; and the vehicular natural gas detection device disclosed by the invention is wide in application range and high in safety.
Description
Technical field
The present invention relates to detection of natural gas device technique field, especially a kind of natural gas used for automobile detection device.
Background technique
LNG Liquefied natural gas LNG as automotive fuel have pollute little, combustion heat value is high, continuous distance travelled is long, Safety performance high, become " green " alternative fuel of a kind of great potential, it has the many advantages such as environmental protection, low running cost, at present apply by increasing commerial vehicle, many car owners have made the dual-fuel automobile of fuel oil/rock gas into the fuel oil type Motor Vehicle of oneself, its advantage one is that cost of use reduces greatly, and the expense of automotive air fuel is 1/2nd of cost of fuel; Two is that noxious emission is little.The vehicle refitting of script fuel oil is become fuel gas vehicle, need to increase vehicle gas cylinder, rock gas just compression is contained in the vehicle gas cylinder of car boot, for ensureing the safety used, mandatory inspection must be carried out according to the rules to vehicle gas cylinder, needing before inspection to process gas cylinder internal rock gas, causing fire or explosive accident to prevent the inflammable gas degree of depth when checking from exceeding standard.
A kind of natural gas recycling device for detecting automotive natural gas bottle is disclosed in CN203176713U, comprise surge flask, storage bottle, nitrogen storage device, concentration of natural gas detection device, buzzer and single chip control unit, between described surge flask and storage bottle, compressor is installed and through tubes connection, described nitrogen storage device is formed primarily of nitrogen pipeline and electromagnetic valve, the pipeline connection automotive natural gas bottle be connected with described electromagnetic valve; Compressor, electromagnetic valve and concentration of natural gas detection device described in described single chip control unit connection control.It can detect in real time to situation remaining in vehicle gas cylinder, but also there is following technical deficiency: 1, can not monitor in real time the temperature of engine compartment; 2, existing detection device does not possess waterproof anti-fog function.
Summary of the invention
The technical problem to be solved in the present invention is: to overcome in prior art not enough, provides one can not only concentration of natural gas in inspection vehicle, and can detect the natural gas used for automobile detection device of temperature of engine compartment.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of automobile-used deflation warning system, described automobile-used deflation warning system comprises controller, and described controller is connected with signal designation alarm, sensor of natural gas and temperature transducer, and described signal designation alarm is arranged on instrument desk; Described signal designation alarm comprises tutorial light and buzzer.
Further, described temperature transducer is arranged in engine compartment.
Further, described sensor of natural gas is arranged on the different parts in car.
Further, described automobile-used deflation warning system comprises LNG liquid gas and CNG rock gas two class deflation warning system.
Further, described sensor of natural gas comprises housing, and described housing comprises base and upper cover, covers and have detection air hole on described.
Further, described instrument desk adopts fire protection flame retarding PC material, and described instrument desk surface adopts the corrosion treatmentCorrosion Science of spark line.
The beneficial effect of technological scheme of the present invention is adopted to be: to be exclusively used in natural gas vehicle and to detect natural gas leakage and report to the police, different parts in car can be arranged on, detect, once gas leakage, alarm signal will be pointed out to main frame on the table, and which road of the corresponding alarm of main frame leaks air and processes potential safety hazard in time; Safety coefficient is high.Leak alarm mainly contains LNG liquid gas, the large class of CNG natural gas leakage alarm two.On liquid gas bus, the detection of gas leak and warning, detect simultaneously and show the temperature of engine compartment.Applied widely, Security is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structured flowchart of the present invention;
Fig. 2 is the structural representation of sensor of natural gas of the present invention;
In figure: 1 is upper cover, 2 is detection air hole, and 3 is base
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of automobile-used deflation warning system, described automobile-used deflation warning system comprises controller, and described controller is connected with signal designation alarm, sensor of natural gas and temperature transducer, and described signal designation alarm is arranged on instrument desk; Described signal designation alarm comprises tutorial light and buzzer.
Working principle: signal designation alarm portion is arranged on instrument desk, alarm buzzer is housed above, the corresponding tutorial light of each gas tank, Test Switchboard, Temperature displaying.After powering on, main frame is reported to the police and is entered self-inspection, and buzzer is three sound, and tutorial light has green to redden look, and numeral method is from showing temperature after 000-999.During normal work, tutorial light is green.Before start, require that driver presses Test Switchboard, now corresponding tutorial light has green to redden look, and buzzer rings, numeral method 888.Unclamp Test Switchboard, tutorial light becomes normal green, and buzzer is sound not.
If the concentration of gas tank gas leakage is greater than 3000PPM, now should report to the police, corresponding tutorial light becomes red by green, and buzzer rings simultaneously.Concentration is lower than 3000PPM, and alarm display is normal, namely tutorial light be green, and buzzer is sound not.
If the line of gas tank and signal processing disconnects, corresponding tutorial light has red green to flash, and check whether corresponding line connects.Numeral method '-E-' will check whether temperature line connects.On a display panel, when the temperature of engine compartment is more than 85 DEG C, buzzer rings reports to the police the normal Temperature displaying of engine compartment; Normal state is recovered, by numeral method temperature value when low dry 85 DEG C
