Abstract
The utility model discloses a meter displaying figures of oil volume in fuel tanks of automobiles, comprising a digital display arranged on instrument panels of cabs, a resistance liquid level sensor arranged in the fuel tanks. The resistance liquid level sensor is connected through an A/D circuit with the input end of an SCM, the output end of which is electrically connected with the digital display and a low oil alarm respectively. With simple structure, low cost and long service life, the utility model can accurately display the figure of the oil volume, alarming when the oil runs low to remind the driver of adding oil timely.
Description
Technical field
The utility model relates to a kind of automotive oil tank oil mass numeral gauging table.
Background technology
The most of pointer structure that adopts of present automotive oil tank fuel level gauge, this oil meter metering is not accurate enough, can only show oil mass roughly, and pointer can with oil in the fuel tank rock and deflection; CN200420068846.0 discloses a kind of automotive oil tank oil mass metering device, be that basal surface appropriate location in automotive oil tank is provided with an electron pressure gage probe, at the bridge instrumentation platform digital indicator is set, the electron pressure gage probe is connected by lead with the fluorescence digital display screen.Measure shortcoming inaccurate, the pointer job insecurity though this digital fuel level gauge has overcome, the cost of the electron pressure gage probe of its use is higher, fragile, and can only demonstrate oil mass, reports to the police and can not hang down oil mass.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, low cost of manufacture, the automotive oil tank oil mass numeral gauging table of long service life.
The further purpose of the utility model is to provide a kind of can also hang down the automotive oil tank oil mass numeral gauging table that oil mass is reported to the police.
The purpose of this utility model is achieved through the following technical solutions: it comprises the digital indicator that is installed in the bridge instrumentation platform, is installed in the liquid level sensor in the fuel tank, and described liquid level sensor is selected resistance-type level transducer for use; Resistance-type level transducer is electrically connected with a single-chip microcomputer input end by the A/D circuit, and the single-chip microcomputer output terminal is electrically connected with digital indicator.Single-chip microcomputer converts actual oil mass to according to the data that the A/D circuit provides, and driving display shows the oil mass data on display screen.
The further purpose of the utility model is achieved through the following technical solutions: described single-chip microcomputer output terminal also is connected with a low oil mass alarm, described low oil mass alarm can be hummer or/and warning lamp, warning lamp preferably is installed on the bridge instrumentation platform, so that observe.The work of low oil mass alarm is by Single-chip Controlling: the oil mass in fuel tank not for a long time, single-chip microcomputer makes low oil mass alarm send alerting signal according to setting value.
Described resistance-type level transducer can be the wire-wound structure of straight barrel type, also can be lever ceramics structure.
Described digital indicator can be charactron or LCD display.
Power supply of the present utility model is provided by the storage battery that automobile self is provided with.
The resistance-type level transducer that the utility model is selected for use, simple in structure than electron pressure gage probe, cost is low, long service life; Select for use the A/D circuit to realize analog to digital conversion, handle, convert actual oil mass to, on display, show, make the oil mass data more accurate through single-chip microcomputer.
Be provided with the scheme of alarm, also have low oil mass and report to the police, the function of reminding the driver in good time to refuel.Use conveniently, application prospect is better.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model one embodiment;
Fig. 2 is a circuit block diagram embodiment illustrated in fig. 1.
Embodiment
