According to the automobile oil level monitoring device, shortcomings in the prior art can be improved; by arranging a double monitoring device with capacitive detection and resistance detection functions in the center of the oil tank, the detection error is reduced.
Description
Technical field
The utility model relates to automotive meter instruments and meters, especially a kind of automobile oil level monitoring device.
Background technology
Automobile show gasoline number, must rely on device for monitoring oil level.When but existing device for monitoring oil level rocks in fluid generation, there is the shortcoming that error is large.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of automobile oil level monitoring device, can improve the deficiencies in the prior art, by be provided with the double monitoring device that condenser type detects and resistance-type detects at fuel tank center, has reduced detection error.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A monitoring device, structure comprises the capacitor that is arranged on fuel tank center, and the height of capacitor is identical with the height of fuel tank, and capacitor side is provided with gap, makes to be interlinked to the outside in capacitor, and fluid frees in and out capacitor by gap; Capacitor arranged outside has resistor disc, and the outside of resistor disc slidably connects brush, and brush is connected with a float, and the two ends up and down of brush and resistor disc contact position are respectively arranged with amortisseur bar; Capacitor and brush are connected to respectively Vehicle Controller, and Vehicle Controller is connected to display terminal.
As preferably, described resistor disc adopts ceramic resistor sheet.
As preferably, described brush adopts Rhometal brush.
As preferably, described amortisseur bar adopts oil resistant rubber.
As preferably, described Vehicle Controller adopts single-chip microcomputer.
As preferably, described display terminal adopts pointer dashboard or digital instrument panel.
The beneficial effect that adopts technique scheme to bring is: the utility model, by monitoring device being arranged on to the center of fuel tank, can reducing to the full extent liquid level and rock the measuring error of bringing.The double monitoring that adopts measurement by capacitance and resistance-type to measure, and the autokinesis that amortisseur bar reduces brush is set on brush, by capacitor, measure the instantaneous oil level of fuel tank center, by measuring resistance, measure the average oil level of position, fuel tank Chinese and Western.Due on brush with amortisseur bar, so when fluid produces fluctuation, brush can acutely not rock along with the fluctuation of fluid, so just improved the authenticity of measurement.When the oil level of measuring when capacitor and the oil level of brush indication exist long relatively large deviation, illustrate that resistance-type measuring appliance exists error or fault.Vehicle Controller gathers the detection signal of resistance-type measuring appliance when resistance-type measuring appliance works, and can improve the authenticity of detection; When error or fault appear in resistance-type measuring appliance, Vehicle Controller gathers the detection signal of measurement by capacitance device, avoids causing whole oil level detecting device to lose efficacy due to error or the fault of resistance-type measuring appliance.Resistor disc adopts ceramic resistor sheet, and brush adopts Rhometal brush, and amortisseur bar adopts oil resistant rubber, can improve the corrosion-resistant degree of resistance-type measuring appliance, extends its serviceable life.Vehicle Controller adopts single-chip microcomputer, and low in energy consumption, stability is strong.
