Description
Technical field
The utility model relates to a kind of oil mass monitoring device of vehicle.
Background technology
Chinese patent literature CN 2859475Y discloses a kind of automobile electrical sub-figure on January 14th, 2006 and has shown oil meter, comprise oil meter, oil meter links to each other with the contact of resistance and the contact on the floating ball lever respectively by two lines, resistance communicates with sheet metal on the wiring board, and oil meter is that digital gauging table automobile electrical sub-figure shows oil meter.This automobile electrical sub-figure shows the oil meter complex structure, the operation underaction.
The utility model content
The purpose of this utility model aims to provide the oil mass monitoring device of a kind of simple and reasonable, flexible operation, efficiency of management height, vehicle applied widely, to overcome weak point of the prior art.
Press the oil mass monitoring device of a kind of vehicle of this purpose design, the ball float and the signal transmssion line that comprise oil meter and be positioned at fuel tank, it is characterized in that also comprising the oil mass signal line, resistance drop volt circuit, A/D convertor circuit, CPU and the wireless transmitter module that are arranged on the vehicle, and be arranged on manager's the information processing platform and the wireless network of operator; One end of oil mass signal line and the signal transmssion line of oil meter join, and the other end of oil mass signal line is connected in series with resistance drop volt circuit, A/D convertor circuit, CPU and wireless transmitter module successively; The information processing platform is connected in series with the wireless network of operator; Wireless transmitter module and wireless network are corresponding to be provided with.
Also be provided with display screen on the described vehicle, display screen inserts the CPU that is used to control and show the oil mass value.
Oil mass signal line on the vehicle in the utility model is connected to the signal end of the oil meter of vehicle, just with oil meter on original signal transmssion line join, pass through resistance drop volt circuit and A/D convertor circuit then, be converted to the numerical value of voltage by CPU, by wireless transmitter module this numerical value is sent to the wireless network of operator again by CPU, wireless network passes to the information that receives the information processing platform of band display, the information processing platform is carried out formula operation by the oil mass numerical tabular that pre-sets, obtain pairing oil mass, at last oil mass is shown in manager's display with tabulation or curvilinear figure, be convenient to manager the oil mass of vehicle is carried out in good time monitoring, thereby improved the efficiency of management.
The utility model can be used for realizing that long-range oil mass to vehicle manages, and manager wherein can be enterprises and institutions such as factory, school or hotel, and it has simple and reasonable, flexible operation, efficiency of management height, advantage of wide range of application.
Description of drawings
Fig. 1 is the block diagram of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, the oil mass monitoring device of this vehicle, comprise oil meter, be positioned at ball float, the signal transmssion line of fuel tank and be arranged on oil mass signal line, resistance drop volt circuit, A/D convertor circuit, CPU and wireless transmitter module on the vehicle, and be arranged on manager's the information processing platform and the wireless network of operator; One end of oil mass signal line and the signal transmssion line of oil meter join, and the other end of oil mass signal line is connected in series with resistance drop volt circuit, A/D convertor circuit, CPU and wireless transmitter module successively; The information processing platform is connected in series with the wireless network of operator; Wireless transmitter module and wireless network are corresponding to be provided with.Also be provided with display screen on the vehicle, display screen inserts CPU, by CPU control and demonstration oil mass value.
Present embodiment adopts following formula one to calculate when carrying out the oil mass conversion:
L={ (N-N
M-1)/(N
m-N
M-1) * (L
m-L
M-1)+L
M-1Formula one,
The oil mass numerical tabular sees the following form:
| Numerical value | Oil mass |
| N m | L m |
| N m-1 | L m-1 |
| N m-2 | L m-2 |
| …… | ?…… |
Wherein, L is an oil mass,
The numerical value that on behalf of CPU, N draw by the A/D convertor circuit conversion,
N
mBe the numerical value that is provided with on the information processing platform,
L
mFor pairing oil mass value is set on the information processing platform,
For example: the oil mass numerical tabular in the information processing platform pre-sets down column data: N
m=360, represent oil mass L
m=60 liters of oil; N
M-1=340, represent oil mass L
M-1=50 liters of oil; At this moment, the voltage value N=354 of the oil mass that CPU newly collects, the above-mentioned formula one of substitution calculate and can obtain the present oil mass L=57 liter of automobile oil.
