, it is necessary to test the performance and accuracy of each part of automobile during automobile production manufactures, such as the transient state oil of automobile
Consume instrument, can not carry out it is self-alignment in the case of, the traceabilities of data is always a knotty problem, and generally Instantaneous Fuel Consumption Monitor is torn open
Descend and return to import producer to be calibrated, calibrate somewhat expensive, and longer at least two moon in cycle, influence project experiment, therefore
A kind of method and system that can be quickly calibrated are provided in the embodiment of the present invention.
Referring to Fig. 1, the calibration method for the Instantaneous Fuel Consumption Monitor that first embodiment of the invention provides, applied to a transient state oil consumption
Instrument calibrating installation, the Instantaneous Fuel Consumption Monitor calibrating installation include controller 10, the magnetic valve 20 that is connected with the controller 10 with
And the electronic scale 30 being connected with the magnetic valve 20, an Instantaneous Fuel Consumption Monitor 100 respectively with the controller 10 and the magnetic valve
20 connections, specifically, methods described includes step S01 to step S02.
Step S01：The instantaneous oil consumption that Instantaneous Fuel Consumption Monitor 100 is all in preset time period is obtained by the controller 10
Value, while weighed by the electronic scale 30 and the Instantaneous Fuel Consumption Monitor 100 is flowed through in the preset time period and from the electromagnetism
The cumulative fuel consumption that valve 20 is fallen.
It should be understood that the upper end of the electronic scale 30 is provided with a measuring cup, fallen for accommodating from the magnetic valve 20
Fuel oil, during work, the controller controls the magnetic valve 20 to turn on, and the fuel oil in the Instantaneous Fuel Consumption Monitor 100 is from described
Fallen into magnetic valve 20 in the measuring cup, electronic scale 30 weighs to the fuel oil in measuring cup again, easy conceivable, Yong Huxu
Measuring cup is cleaned in advance and carries out zero point and is weighed, and to reduce weighing error, specifically, the electronic scale 30 needs high accuracy, it is surveyed
Accuracy of measurement needs to reach 0.1g, more than range 5kg, to reach measurement demand.
For example, (i.e. preset time period is one minute) Instantaneous Fuel Consumption Monitor all winks are gathered in 1 minute by controller 10
When fuel consumption values, while automobile engine is consumed in 1 minute the gross mass of fuel oil is weighed (i.e. by high-precision electronic scale 30
Cumulative fuel consumption).
Step S02：The oil consumption total amount corresponding to the summation of all instantaneous fuel consumption values and institute are calculated by the controller
State the difference of cumulative fuel consumption.
It is to be understood that in test process, Instantaneous Fuel Consumption Monitor measure in real time the unit of display for kg/hr, such as
In console on being installed to automobile, then the synthesis by a variety of data, such as tire wheelbase, gear data, conversion obtain list
Position is to rise/hundred kilometers.
Therefore, in preset time period, there can be multiple instantaneous fuel consumption values, the summation of all transient state fuel consumption values is removed in pre-
If the time of period, you can obtain the gross mass for the fuel oil that Instantaneous Fuel Consumption Monitor is consumed in preset time period, then by transient state

The instantaneous fuel consumption values of instrument are consumed, to obtain the instantaneous fuel consumption values of a display and include the instantaneous fuel consumption values of display in the wink
On state fuel consumption meter.
When showing instantaneous fuel consumption values, only need to by it is currently detected be consumption that instantaneous fuel consumption values are shown according to instant oil consumption instrument
Oil mass does corresponding adjustment with the deviation of the cumulative fuel consumption of actual consumption, you can is accurately shown instantaneous fuel consumption values.
For example, setting in the present invention, preset difference value is 0.09L, and the fuel consumption of Instantaneous Fuel Consumption Monitor is total in 1 minute after conversion
Measure as 1L, and total amount of fuel that high-precision electronic scale is weighed to is 0.9L, therefore, deviation 0.1L, deviation ratio is positive
Percent 1, more than preset difference value 0.09L, when Instantaneous Fuel Consumption Monitor is shown, be by each transient state fuel consumption values up-regulation 1 percent
Can, when such as total amount of fuel for being weighed to of high-precision electronic scale is 0.9L, deviation 0.05, less than preset difference value 0.09L, then wink
State fuel consumption meter is shown by the transient state fuel consumption values detected.
The calibration method of above-mentioned Instantaneous Fuel Consumption Monitor, it is all that Instantaneous Fuel Consumption Monitor 100 in preset time period is obtained by controller

Rapid S12.
Step S10：The preset time period is divided into multiple sub- periods, and obtains corresponding rank in multiple sub- time ends
The instantaneous fuel consumption values of section, while corresponding stage fuel consumption in multiple sub- periods is obtained by the controller 10.
For example, continuous three are gathered in 20 seconds (when i.e. default by main control computer or PLC (controller 10)
Between Duan Weiyi minutes, the period be 3 20 seconds) the stage of Instantaneous Fuel Consumption Monitor 100 instantaneous fuel consumption values, while pass through high-precision electricity
Sub- scale 30 weighs the gross mass (i.e. stage oil mass) of the fuel oil that automobile engine is consumed in each 20 second minute.
Step S11：The controller 10 calculates the difference of the stage instantaneous fuel consumption values and the stage fuel consumption, with
To a stage adjustment amount.
Step S12：When the difference exceedes preset difference value, the instant oil consumption instrument is adjusted according to the stage adjustment amount
Corresponding each stage instantaneous fuel consumption values, to obtain the instantaneous fuel consumption values of display.
