Abstract
The invention discloses a device detecting the quantity of oil in an oil tank. The device comprises a power adapter and is characterized by further comprising a main processor, a pressure sensor and a signal transceiver, wherein the main processor is connected with the power adaptor, and the pressure sensor and the signal transceiver are connected with the main processor; the pressure sensor is arranged at the bottom of the oil tank. The device has the advantages of being simple in structure, capable of effectively detecting the quantity of the residual oil in the oil tank, and high in applicability.
Description
Technical field
The present invention relates to a kind of auto parts and components, specifically a kind of fuel tank fuel quantity pick-up unit.
Background technology
Fuel-quantity transducer principle is mainly by the resistance in fuel-quantity transducer inner installation reluctance switch and various different resistances at present.When in automotive oil tank, oil level changes, fuel-quantity transducer float is opened the reluctance switch of differing heights.Fuel-quantity transducer is the different internal resistance reflection automobile Fuel Remained volume percent of output externally.If fuel tank volume, shape are changed, need redesign build-out resistor according to fuel tank volume and the respective function of height, complex process and cost are higher.
Summary of the invention
The object of the invention is the deficiency existing in order to solve above-mentioned background technology, propose a kind of simple in structure, can effectively detect mailbox Fuel Oil Remaining, fuel tank fuel quantity pick-up unit that applicability is wide.
In order to realize above object, a kind of fuel tank fuel quantity pick-up unit provided by the invention, comprises power supply adaptor, it is characterized in that: also comprise the primary processor being connected with power supply adaptor, the pressure transducer being connected with primary processor and signal transceiver; Described pressure transducer is located on the inwall of fuel tank bottom.
Beneficial effect of the present invention: one, owing to adopting the structure that pressure transducer is set on the inwall of fuel tank bottom, carry out computed altitude by liquid pressure, in fuel tank, Fuel Oil Remaining, only in highly relevant, calculates convenient; Its two, adopt a pressure transducer to replace multiple resistance, structure is more simple, applicability is stronger.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
In figure: power supply adaptor 1, primary processor 2, pressure transducer 3, signal transceiver 4.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment: as shown in Figure 1, a kind of fuel tank fuel quantity pick-up unit that the present invention is designed, comprises power supply adaptor 1, it is characterized in that: also comprise the primary processor 2 being connected with power supply adaptor 1, the pressure transducer 3 being connected with primary processor 2 and signal transceiver 4; Described pressure transducer 3 is located on the inwall of fuel tank bottom.
According to formula:
P = ρgh （1）
In formula (1), P is that pressure transducer 3 is at the suffered pressure of mounting points; ρ is fluid to be measured density; G is acceleration of gravity; H is the vertical range of sensor to the water surface.The pressure that known pressure transducer 3 is subject to is relevant with the height of the density of liquid, acceleration of gravity, liquid level.In the time of actual measurement, P is actually atmospheric pressure and liquid level pressure sum, that is:
P = P
0+ ρgh （2）
Have:
P - P
0 = ρgh （3）
Formula (3) illustrates the poor of 3 actual total pressures that are subject to for pressure transducer 3 of suffered liquid pressure of pressure transducer and atmospheric pressure.Can obtain thus:
h=( P- P
0) /ρg （4）
When fuel level in tank changes, can calculate according to formula (4) height of oil level.
In primary processor 2, input the level height of this fuel tank and the funtcional relationship of fuel oil volume, corresponding the level height detecting fuel oil volume, do data processing with software.Output signal to panel board, oil mass information is presented on panel board.
During at every turn to new fuel tank coupling, fuel oil height and Fuel Remained volumetric parameter are demarcated, and need not be changed hardware, reach unitized object.
The above, be only preferred embodiment of the present invention, not structure of the present invention done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical scheme of the present invention.
Claims (1)
1. a fuel tank fuel quantity pick-up unit, comprises power supply adaptor (1), it is characterized in that: also comprise the primary processor (2) being connected with power supply adaptor (1), the pressure transducer (3) being connected with primary processor (2) and signal transceiver (4); Described pressure transducer (3) is located on the inwall of fuel tank bottom.
