Description
The present invention relates to a kind of computer fuel charger flow rate calculation method, be particularly suitable for computer fuel charger and fluid flow and calculate application.
For a long time, the FL/MTR of the employed fuel oil computer fuel charger in market basically all is to adopt volumetric metering type product.At work; The metering piston of positive displacement flowmeter receives the promotion of oil liquid pressure; In the motion process of reciprocation cycle, constantly promote the rotation of metering device Rotating bend; The rotation of Rotating bend has driven the rotation of gage probe, and the metrical pulse signal conveys of generation is made handled control to microcomputer system after microcomputer system is handled signal.
The flow rate calculation mode of present positive displacement flowmeter is with the equivalent pulse stored counts of mechanical volume.Positive displacement flowmeter is the complicated accurate machine construction of a cover; Because of volumetric metering piston and leather cup constantly move; Exist the mechanical moving element wearing and tearing and receive ambient temperature and the fact of breathing, and mechanical type error adjustment means are limited, so metering error is relatively large.And the positive displacement flowmeter volume is bigger, and working accuracy and assembly technology require very high, and it is high to cause the FL/MTR cost of product to occupy.And positive displacement flowmeter the time receives the effect of mechanical moving element resistance in work, and liquid flowing resistance increases, and has influence on directly that fuel charger is fuel-displaced can not to reach bigger flow.Influenced by composite factor, the daily maintenance cost of fuel charger user is also higher relatively.
The objective of the invention is to propose a kind of flow rate calculation method of computer fuel charger FL/MTR, the work that makes the metering of common discharge meter lean on hardware volume dimensional accuracy to guarantee is converted into and lets software do, and realizes that complete machine manufacturing cost-cutting improves system performance.
Compare with the equivalent cumulative measurement method of existing fuel charger, it is simple that the present invention has a method of calculating, avoided the influence factor of the mechanical equivalent precision of fuel charger FL/MTR basically; Adopt intelligent error compensating method; It is more accurate to make complete machine have a Fuel-filling metering, receives such environmental effects littler, and whole aircraft reliability is higher; Manufacturing cost is lower, the characteristics that maintenance cost is lower relatively.
The flow rate calculation method that the present invention proposes comprises computing formula and pulse equivalency parameter list and method of application.
Computing formula is the core constant parameter with the pulse equivalency, and pulse number is a variable, by formula: V=∑ Kp calculated flow rate; Wherein, V: flow volume, K: pulse equivalency parameter, p: metrical pulse number.
It is characterized in that; The pulse equivalency parameter K of every FL/MTR confirms that method is: through FL/MTR to be tested a graduated cylinder that meets national measurement instrument technical standard is injected oil plant and the pulse count sent of recording impulse information sensor simultaneously on the fuel charger test cell;, oil plant shuts down when reaching graduated cylinder sampling unit volume; Accurately measure the volume liter data of graduated cylinder sampling, again divided by the pulse cumulative total, the gained quotient is the equivalent parameter K of this FL/MTR.
The pulse equivalency parameter list; With national measurement standard graduated cylinder is measurer; Be divided into seven zones by the terrestrial latitude symmetry; Classify by each regional height above sea level (high, medium and low) barometric pressure and seasonal ambient temperature (high, medium and low) characteristic, the fuel charger test cell are in actual oiling working environment, do the sampling test of nine standard pulse equivalent parameters at each zone; Produce totally 63 representative pulse equivalency parameter lists of pulse equivalency parameter K composition like this, be stored in the fuel charger computer program.Fuel charger is set up a zone and elevational position heading code by the region; According to position code and the current date that characterizes the seasonal temperature rule, select wherein can represent a K parameter of environmental characteristic to participate in calculating during the computer program calculated flow rate with the mode of sitting in the right seat.
Use the present invention, reduced the machining accuracy requirement to FL/MTR, can make the complete machine metering more accurate, flow is bigger, and reliability is higher, makes complete machine produce assembly technology and obtains simplifying, and cost is reduced.
The flow rate calculation method that the present invention proposes; Formula is simple, and the canonical parameter of participating in calculating all obtains from reality is accurately measured, and adopts the intelligent pattern of software parameter table; Can eliminate the accumulated error of FL/MTR greatly, can greatly approach and obtain approximate accurate flow accumulation result.
Enforcement of the present invention and effect are described below:
Effect of the present invention is that traditional fuel charger is made in the link, and the workmanship of common positive displacement flowmeter will lean on the hardware size precision to guarantee, lets software realize and be converted into.So FL/MTR just need not reduce the FL/MTR manufacture difficulty cost is reduced greatly, and make that simultaneously the metering of fuel charger complete machine is more accurate the high-precision processing requirement of mechanical volume data, unfailing performance obtains bigger raising.Compare the fuel charger that adopts conventional art and realize more easily that also big flow refuels.
Comprise computing formula and pulse equivalency K parameter list and method of application in the designed flow method of calculating of the present invention.
Computing formula V=∑ Kp
Wherein, V: flow volume, K: pulse equivalency parameter, p: metrical pulse number;
For example, K=1ml, during p=10000, V=∑ Kp=10000ml representes this oiling 10000ml.
Whether pulse equivalency K parameter is accurate, directly has influence on flow rate calculation result's quality height, so pulse equivalency K Determination of Parameters seems extremely important.Very enlightenment property of a classical story is arranged; It is said that Edison has taken a special-shaped glass container as his student of examination question examination then; How many be capacity of this container? His student is awfully busy for this reason, has used up the method for calculating of various higher mathematics, does not all calculate.Edison has seen directly and has shaken the head, and tells them, and " how not using simple method solves.Filling water in the container, pour measuring cup again into and measure not with regard to knowledge of result?
The present invention is inspired by this exactly; Confirm accurate pulse equivalency K parameter with straightforward procedure: carry out the oil plant sampling with any FL/MTR; Fuel charger injects oil plant and the pulse count sent of recording impulse information sensor simultaneously to a graduated cylinder that meets national measurement instrument technology related request;, oil plant shuts down when reaching graduated cylinder sampling unit volume; Use unit volume divided by the pulse cumulative total then, promptly obtain the equivalent parameter K of this FL/MTR to be tested, just as people's fingerprint belongs to unique respective value.How many height of its precision is directly proportional with initial sampling, has just avoided the difficulty of machining accuracy, and reaches the final purpose that improves measuring accuracy.
Same reason; In complete machine manufacturing process, every FL/MTR equivalent parameter K value is separately confirmed in check and correction on the fuel charger test desk, refuels arbitrarily earlier; Shut down the volume amount of back oil plant that accurately measurement adds; Divided by the pulse cumulative total, its quotient is the number of liter accurately that liquid is flow through in each pulse representative again, is the unique corresponding equivalent parameter K of this FL/MTR.
Because the regional height above sea level barometric pressure at each fuel charger work place; The ambient temperature characteristic has nothing in common with each other; Always there is difference so be distributed in each regional accurate conformability of fuel charger gas filed; Employing meets the parameter intelligent compensation way of fuel charger place of working environmental conditions, the accuracy that the quantity that just can realize refueling is calculated the biglyyest.This just need set up one " pulse equivalency parameter list ".
The earth is divided into the torrid zone, subtropics, temperate zone, seven zones, frigid zone by north and south latitude symmetry; Carry out inducing classification by each regional height above sea level (high, medium and low) barometric pressure and seasonal climate temperature (high, medium and low) characteristic; The oiling working environment of simulation fuel charger; With national measurement standard graduated cylinder is the sampling measurer, and each zone is done the sampling test of nine standard pulse equivalent parameters; Get 63 pulse equivalency parameter group so altogether and become a K parameter list.
Behind classification simulation environment experiment test, confirm that the pulse equivalency parameter K is as fuel charger place of working pulse equivalency parameter.All can be endowed after every fuel charger production is dispatched from the factory and installed and use the regional location heading code; Computer program is according to regional height above sea level and the tagsorts such as date that characterize temperature in season during oiling; Set up equivalent parameter math modeling; With the look-up method of sitting in the right seat, the some parameter K in the strobe pulse equivalent parameter list are participated in the calculating of flow V, and are very simple.
Strict saying, the difference of the each volume read-out size of client, the result does accurate measurement to oiling, always has a little error.Adopt " intelligent nonlinear error compensation method " that error is reduced as much as possible.
Method is that several volume read-outs (large, medium and small) sampling point is confirmed in experiment, makes accurate matching measurement with the standard graduated cylinder, determines error information, and these data are built up one " compensating parameter table " is stored in the fuel charger computer program.In refueling process, be directed against the large, medium and small oiling total amount of different user, sit in the right seat with look-up method and select pairing error compensation value in the compensating parameter table, then can the oiling error further be limited in more basically.
Be last up till now; Existing in the world fuel charger is at-20 ℃ of the two poles of the earth perhaps+50 ℃ does not have effective metering error compensatory device basically in the extreme working environment; Standard is set up in the simulation actual environment sampling that the present invention proposes; Software computation of table lookup method can greatly be approached accurate measurement, these be a kind of new ideas of " software algorithm FL/MTR ".Social demand to reality has positive effect.
