Abstract
The utility model relates to a leakage alarm for a gas automobile. According to the leakage alarm, a central processing unit (CPU) is connected with a power supply, a buzzer, an indicator lamp and an interface, and the power supply is connected with a switch. The leakage alarm is characterized by also comprising a plurality of natural gas probes, wherein interfaces, indicator lamps, sensors and sensor probes are arranged in the natural gas probes; the interfaces of the natural gas probes are connected with the interface connected with the CPU by a wiring harness. The leakage alarm has the advantages that the gas leakage condition of the gas automobile can be discovered in time to warn drivers and passengers to leave in time and avoid accidents, so the leakage alarm has a great significance of protecting life and properties of people.
Description
Technical field
The utility model relates to a kind of gas combustion automobile leakage alarm appearance.
Background technology
Just exist so that natural-gas-powered automobile is general at present, gas leakage will bring life danger to chaufeur and passenger.Use if gas combustion automobile is long-time, in case gas leakage takes place, consequence is with hardly imaginable.How taking precautions against this type phenomenon and take place, is the problem that we need solve.
Summary of the invention
The utility model is in order to prevent trouble before it happens; In time find the problem of gas leakage, the technical scheme of employing is: a kind of gas combustion automobile leakage alarm appearance, and it is formed CPU and is connected with power supply, buzzer phone and indicator lamp and interface respectively; Power supply is connected with switch; It is characterized in that: also comprise several natural fuels probes, be provided with interface, indicator lamp and sensor and sensor probe in the natural fuels probe, the interface of natural fuels probe connects through wire harness with the interface that is connected CPU.
During use, controller is installed in the automobile cab conspicuous position; Several natural fuels probes are distributed in each position that vehicle possibly leak natural fuels, confirm used quantity as required; Temp probe is installed in the machinery space.In case detected gas leakage, the gas sensor in the combustion gas probe will send electronic signal to controller immediately, if its concentration reach the warning concentration that controller is set, controller will be simultaneously with sound with manifest the Warning light dual mode and give the alarm.When engine compartment temperature was higher than the temp probe design temperature, controller received temperature sensor signal, sent the sound and light alarm signal.
The beneficial effect of the utility model is in time to find the gas leakage situation and the machinery space overtemperature situation of gas combustion automobile, and caution driver and passenger in time leave, and prevents unexpected the generation, and the safety of life and property to the protection people has crucial meaning.
Description of drawings
Fig. 1 is the utility model concrete structure scheme drawing.
Fig. 2 is the internal circuit configuration scheme drawing of natural fuels probe.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of gas combustion automobile leakage alarm appearance; It is formed CPU and is connected with power supply, buzzer phone and indicator lamp and interface respectively; Power supply is connected with switch; It is characterized in that: also comprise several natural fuels probes, be provided with interface, indicator lamp and sensor and sensor probe in the natural fuels probe, the interface of natural fuels probe connects through wire harness with the interface that is connected CPU.
Be provided with the natural fuels gas sensor in the natural fuels probe, its schematic circuit diagram are seen Fig. 2.After controller power source is connected; The heating power supply energising of probe is heated to its operating temperature to the natural fuels gas sensor, if natural gas leaking takes place this moment; When natural fuels passes through gas sensor; With its generation chemical reaction, cause the magnitude of voltage of gas sensor to change, the magnitude of voltage of different concentration of natural gas gas sensors is also inequality.Probe is transferred to controller with detected magnitude of voltage variable signal, and controller CPU is handled this signal, and greater than the concentration value of setting among the CPU, then this moment, buzzer phone and warning indicator lamp circuit were connected like concentration at this moment, and controller sends the sound and light alarm signal.
When the temperature of machinery space surpassed the design temperature of temperature sensor in the temp probe, the circuit of temp probe was connected, and CPU receives electric signal in the controller, and buzzer phone and warning indicator lamp circuit are connected, and controller sends the sound and light alarm signal.
