Abstract
The utility model discloses an automobile oil quantity detection alarm device, which comprises an oil quantity sensor for detecting oil level and an alarm circuit which is connected with the oil quantity sensor, wherein the alarm circuit comprises a power supply module and a single chip microcomputer which is connected with an automobile key switch in series, and the single chip microcomputer is respectively connected with an alarm and the power supply module. The automobile oil quantity detection alarm device has ingenious conception and simple structure, and can detect the change of the oil level in an oil tank through the oil quantity sensor. When the oil level changes, the single chip microcomputer can drive the alarm to alarm, thieves can be scared away when hearing sound, and people also can check the oil tank in time when hearing the sound, thereby being capable of effectively preventing oil from being stolen. Simultaneously, the automobile oil quantity detection alarm device has low cost, and is beneficial to popularize and apply.
Description
Technical field
The utility model relates to a kind of warning device, is specifically related to a kind of being installed in and can effectively prevents the automobile oil mass detection alarm device that oil goes adrift on the automobile.
Background technology
At present, along with the rise of the in short supply and oil price of the energy, not only have the difficult problem of refueling, and increasing lawless person occurs and rely on and steal oil and seek exorbitant profit, it is anti-to allow people's air defense be unequal to.Especially the people's drive time that runs long-distance transport is long, car can be parked in the roadside when feeling fatigue and have a rest, but wake up from a sleep, and discovery oil is snatched a moment but feels simply helpless.People go adrift in order to prevent oil, what have locks fuel tank, and what have thickeies the fuel tank iron plate, and what also have installs anti-theft device at the fuel tank oil-in ... though taked the various precautionary measures, oil in the fuel tank is still usually going adrift unconsciously, results in hand cramps to people.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of being installed in can effectively prevent the automobile oil mass detection alarm device that oil is stolen on the automobile.
Technical scheme: for solving the problems of the technologies described above, a kind of automobile oil mass detection alarm device of the present utility model comprises fuel-quantity transducer that detects oil level and the warning circuit that is connected with fuel-quantity transducer, described warning circuit comprises the single-chip microcomputer that is connected in series mutually with the car key switch, is connected with alarm and power module on the single-chip microcomputer respectively.
It is the integrated circuit power supply that described power module adopts the 78L0578L12 cake core to forward the 24V voltage of automobile to 5V.78L0578L12 cake core operating voltage range is wide, can be between 16～30V operate as normal.
Described alarm is one or both in hummer and the external loudspeaker.Hummer is installed in pilothouse, and the driver can hear warning when pilothouse; External loudspeaker can be matched the high-decibel loudspeaker, and speaker sound can reach 90 decibels, makes the driver also can clearly hear alarm sound outside hundred meters.
A kind of automobile oil mass detection alarm device of the present utility model is connected in series single-chip microcomputer in use with automobile key switch, automobile key switch open, the turn-off transient single-chip microcomputer all can read signal.When key switch was opened, warning circuit was in closed condition.When key switch is closed, warning circuit is started working, can gather current oil level and be stored in the single-chip microcomputer storer at the turn-off transient fuel-quantity transducer, the every 8S of single-chip microcomputer detects oil level and makes comparisons with oil level data before, if oil level descends rapidly (stealing oily situation) or detects less than then Micro Controller Unit (MCU) driving hummer and the warning of high-decibel loudspeaker of oil level (cutting off the line situation), thereby reminds car owner driver to go to check that fuel tank sees if there is the people and steals oil.
Beneficial effect: a kind of automobile oil mass detection alarm device of the present utility model is skillfully constructed, and is simple in structure, can detect the variation of oil level in the fuel tank by fuel-quantity transducer; When oil level changes, monolithic opportunity driven alarm equipment alarm is stolen oily thief and is heard that sound can be frightened away, and people hear that sound also can in time check fuel tank, can prevent effectively that oil from going adrift; Simultaneously, the utility model is with low cost, helps promoting the use of.
Description of drawings
Accompanying drawing is a circuit structure block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in drawings, a kind of automobile oil mass detection alarm device of the present utility model comprises fuel-quantity transducer that detects oil level and the warning circuit that is connected with fuel-quantity transducer, warning circuit comprises the single-chip microcomputer that is connected in series mutually with the car key switch, is connected with alarm and power module on the single-chip microcomputer respectively.
Single-chip microcomputer adopts PIC12F675, can support wide voltage from 2.0V to the 5.5V operate as normal, have the inner 4MHz oscillator of high precision, the analog to digital converter module of 10 bit resolutions, the back off timer that powers on (PWRT) and oscillator starting of oscillation timer (OST), temperature grade is-40 ℃ to 85 ℃.
It is the integrated circuit power supply that power module adopts 78L05 78L12 cake core to forward the 24V voltage of automobile to 5V, and 78L05 78L12 cake core operating voltage range is wide, can be between 16～30V operate as normal.Alarm is one or both in hummer and the loudspeaker, and hummer is installed in pilothouse, and the driver can hear warning when pilothouse; Loudspeaker can be matched the high-decibel loudspeaker, and speaker sound can reach 90 decibels, make the driver also can clearly hear alarm sound outside hundred meters.
The utility model adopts 6 pin connectors, 6 linear speeds are respectively battery power positive pole, battery power negative pole, have the two sensors signal just, oil meter oil mass signal input end, high-decibel loudspeaker positive pole and key switch signal.When the key switch unblanking is 24V, is unsettled when closing; High-decibel external loudspeaker negative pole directly links to each other with ground without this circuit of reporting to the police.The maximum drive power of warning circuit is 5W (24V 200mA).
A kind of automobile oil mass detection alarm device of the present utility model is connected single-chip microcomputer in use with automobile key switch, automobile key switch open, the turn-off transient single-chip microcomputer all can read signal.When key switch was opened, warning circuit was in closed condition.When key switch is closed, warning circuit is started working, can gather current oil level and be stored in the single-chip microcomputer storer at the turn-off transient fuel-quantity transducer, the every 8S of single-chip microcomputer detects oil level and makes comparisons with oil level data before, if oil level descends rapidly (stealing oily situation) or detects less than then Micro Controller Unit (MCU) driving hummer and the warning of high-decibel loudspeaker of oil level (cutting off the line situation), thereby reminds car owner driver to go to check that fuel tank sees if there is the people and steals oil.
