Abstract
The invention discloses a fuel display system for an automobile, belonging to the mechanical-electronic control field. The fuel display system for the automobile consists of a fuel tank, two flow meters, a fuel pump, a processor, a display and an alarm, wherein the display is a digital liquid crystal display, and the alarm sounds for alarm. According to the fuel display system, the flow meter obtains the information of the oil loading and unloading quantities in the fuel tank in real time, and the processor processes the information so as to obtain the remaining oil quantity in the fuel tank and display the remaining oil quantity on the display. The fuel display system for the automobile has the advantages of stable performance, simple structure and capability of knowing the remaining oil quantity in the fuel tank in real time.
Description
Technical field
The present invention relates to a kind of display system, more particularly, relate to a kind of vehicle fuel display system.
Background technology
Along with the continuous development of auto industry, all is furnished with the fuel oil display system on all kinds of automobiles.Orthodox car fuel oil display system generally adopts the mechanical floats device; No matter fuel oil is in a high position or low level in the fuel tank; The principle that all adopts the buoyancy of fuel oil to change the relative position of float to show qualitatively the surplus of fuel oil in the fuel tank, and comes to show qualitatively the surplus of fuel oil in the fuel tank through the fuel oil pilot lamp.Its shortcoming of this display mode has: 1, can only show the surplus of fuel oil in the fuel tank qualitatively, demonstration that can not be quantitative; 2, when automobile up and down during the abrupt slope, because fuel tank is irregular, this display mode more can accurately not show the surplus of fuel oil in the fuel tank, even can occur that fuel tank is actual to have oil but the fuel oil pilot lamp shows the phenomenon of not having oil.
Chinese patent ZL201120069979.X; Granted publication day is on November 09th, 2011; Invention and created name is: the combination instrument that can show instantaneous oil consumption, non-pointer fuel oil and water temperature indication; This device comprises box body, door is installed on the front panel of box body opens pilot lamp, gear pilot lamp, mileage subtotal display screen and mileage display screen, and characteristic is: water temperature display screen, fuel oil display screen and instantaneous oil consumption display screen also are installed on the front panel of box body; On circuit board, be provided with single-chip microcomputer, fuel oil signal drive circuit, water temperature signal driving circuit and instantaneous oil consumption signal drive circuit, the demonstration range of instantaneous oil consumption display screen is 0-20L/100KM.This device have instantaneous oil consumption, non-pointer fuel oil and water temperature show organically combine and show, practice thrift the instrument desk space simultaneously, visual discrimination is clear, handsome in appearance; But this device can not the display automobile fuel tank in Fuel Oil Remaining, this can make the driver can't understand the information of Fuel Oil Remaining in the fuel tank in real time.
Summary of the invention
The technical matters that the present invention solved is to provide a kind of simple in structure, precise and stable, the vehicle fuel display system that can understand Fuel Oil Remaining information in the fuel tank in real time.
For solving above technical matters, the present invention is achieved through following technical scheme.
A kind of vehicle fuel display system comprises fuel tank, fuel pump, display, and it also comprises flowmeter A, flowmeter B, processor and alarm; Above-mentioned parts connected mode is: flowmeter A links to each other with the oil filler of fuel tank; The output terminal of fuel tank links to each other with fuel pump; The oil-out of fuel pump links to each other with flowmeter B; The input end of processor links to each other with flowmeter B with flowmeter A respectively, output terminal links to each other with alarm with display respectively, and said processor receives and handles two flowmeters and transmits next data and give display and alarm with result transmission.
As a kind of optimization, aforementioned display device is a liquid crystal digital display, and above-mentioned alarm is the voice prompt alarm device.
Adopt technical scheme provided by the invention, compare, have following remarkable result with existing known technology: 1, stable performance, simple in structure; 2, adopt the flowmeter metering, being the Fuel Remained amount with the difference of calculating fuel tank turnover oil mass is principle, and accuracy is high; 3, the interior Fuel Remained amount of fuel tank shows intuitive and convenient with the form of numeral; 4,,, can not occur that fuel tank is actual to have oil but the fuel oil pilot lamp shows the phenomenon of not having oil even if fuel tank is irregular when automobile up and down during the abrupt slope yet.
Description of drawings
Fig. 1 is the functional-block diagram of vehicle fuel display system of the present invention.
Embodiment
For further understanding content of the present invention, the present invention is further described below in conjunction with accompanying drawing.
As shown in Figure 1, this vehicle fuel display system is made up of fuel tank, two flowmeters (flowmeter A and flowmeter B), fuel pump, processor, display and alarm.The connected mode of above-mentioned parts can be known from Fig. 1: flowmeter A links to each other with the oil filler of fuel tank; The output terminal of fuel tank links to each other with fuel pump; The oil-out of fuel pump links to each other with flowmeter B, and the input end of processor links to each other with flowmeter B with flowmeter A respectively, output terminal links to each other with alarm with display respectively.
Below in conjunction with embodiment the present invention is done further description.
This vehicle fuel display system, when the automobile oil, the flowmeter A that is positioned at the fuel tank filler place records the oil inlet quantity of fuel tank, and the real time data information of this oil inlet quantity is sent to processor and stores; In the vehicle traveling process; The flowmeter B at fuel pump outlet place also records the amount of fuel that fuel pump pumps in the fuel tank in real time; And this real time data information that pumps oil mass reached processor; Processor is with certain frequency the oil inlet quantity data that will store and the real-time amount of fuel data subtraction that pumps; And with operation result be in the fuel tank in real time Fuel Oil Remaining be presented on the display with the form of numeral, simultaneously with in the fuel tank in real time the Fuel Oil Remaining data storage in processor as next execution cycle by decrement.
This vehicle fuel display system when automobile adds on the oil cap behind the fuel tank lock, is positioned at the flowmeter A break-off at fuel tank filler place, till opening fuel tank lock next time and refueling.When automobile fuel filler, be stored in processor after real surplus oil mass data can add up with the real time data of this volume read-out in the last time fuel tank.When motor car engine shuts down, the flowmeter at fuel pump outlet place
BRecording the amount of fuel that fuel pump pumps in the fuel tank in real time is zero, and promptly the processor decrement of this moment is zero.When parking; System along with closing of car load Circuits System; And with real surplus oil mass memory in the fuel tank in processor, when the automobile circuit system started once more, memory real surplus oil mass data in the fuel tank in the processor just can be presented on the display.
This vehicle fuel display system, when the real surplus oil mass was lower than a certain setting value in the fuel tank that display shows, alarm can the voice suggestion driver will in time replenish fuel oil.
