Before Fuel Oil Remaining judges, the virtual oscillation power corresponding relation matching experiment of rotating speed-single-point and oil consumption need to be carried out
Coefficient estimates experiment.
Obtain this engine by the raw voltage signals of the vibrating sensor output installed on the attached body of each engine
The principle of rotating speed and Fuel Oil Remaining is:
(1) to vibrating sensor output turnover rate be fsHz(is the sample frequency of vibrating sensor) primary voltage
Signal carries out middle position mean filter, and obtaining turnover rate is fuThe equal threshold voltage of middle position of hz, wherein,
fu=1/tu(2)
I.e. fuIt is state update cycle tuInverse, represent state turnover rate.
(2) process of middle position mean filter is: two parameters of setting, i.e. low level filtering factor flWith high-order filtering factor fh,
Represent the ratio shared by the too low or too high sampled value of the numerical value causing due to environmental disturbances respectively, the two satisfaction:
fl> 0, fh>0,0<fl+fh< 1 (3) by tuThe t being obtained by vibrating sensor in timeu·fsIndividual magnitude of voltage sequence,
And remove minimum tu·fs·flIndividual numerical value and highest tu·fsfhIndividual numerical value, to remaining tu·fs(1-fl-fh) individual
Median takes average, is defined as middle position equal threshold voltage vm.
(3) in order to further filter out the noise in the equal threshold voltage of middle position, and this method is enable to be applied to engine speed
The situation of dynamic change, filters the high-frequency noise causing because rotation speed change leads to frequency alias, in actual measurement rotating speed
During, need to make further filtering process to middle position average voltage.
(4) assume that the equal threshold voltage of middle position acts on unit resistance, corresponding power definition is single-point virtual oscillation power pv
(corresponding to vibrating sensor mount point):
In formula, r0Represent unit resistance, i.e. r0=1 ω, then pvWithIt is numerically equal.Note, single-point is virtual to shake
The dynamic power actual vibration power that not vibration signal has at vibrating sensor mount point, and it is merely possible to a measurement
The index of intensity is vibrated, for matching with engine speed at mount point.
(5) during engine work, the rotation of its rotating shaft is the main driving source of attached body vibration, and rotating speed is faster, then attached body shakes
Dynamic stronger, the voltage of vibrating sensor output is also bigger, and the virtual oscillation power of corresponding single-point is bigger, and therefore, single-point is empty
Intend oscillation power and engine speed positive correlation, by priori experimental data, corresponding relation therebetween can be fitted,
According to this fit correlation, it is capable of tachometric survey by measuring the virtual oscillation power of single-point.
(6) carry out needing yacht state by netting twine during rotating speed-single-point virtual oscillation power corresponding relation matching experiment
The device Host of monitoring terminal equipment is connected with computer, on the one hand, strong to characterize vibration at vibrating sensor collection mount point
The voltage signal of strong degree, calculates the virtual oscillation power of single-point, and uploads to computer by netting twine；On the other hand, operator
Member is with the revolution counter measurement rated rotational frequency corresponding with the virtual oscillation power of single-point, and is input in computer.By computer root
Simulate rotating speed-single-point virtual oscillation power corresponding relation according to the sample data of the virtual oscillation power of single-point and rated rotational frequency, and
Download to the device Host of yacht status monitoring terminal device by netting twine, calculate engine as by the virtual oscillation power of single-point
The foundation of rotating speed.Assume to obtain sample point (pv1, n1), (pv2, n2) ..., (pvm, nm), wherein m represents the number obtaining sample point
Mesh, pv1, pv2..., pvmRepresent engine stabilizer in different rotating speeds, calculated by the raw voltage signals that vibrating sensor exports
The different virtual oscillation power of single-point of the numerical value that obtains, n1, n2..., nmRepresent the corresponding rotational speed criteria recording with revolution counter
Value.Order
itp_pv=[pv1, pv2..., pvm] (5)
itp_n=[n1, n2..., nm] (6)
With sequence itp_pvWith itp_n as sample point, apply interpolation method to be fitted, obtain single-point virtual vibration work(
Rate pvSegment increasing corresponding relation with engine speed n:
n=gi(pv), pv∈[pvi, pvi+1), i=1,2 ..., m-1,
In formula, giIt is single-point virtual oscillation power pvWith rotating speed n in power interval [pvi, pvi+1) in corresponding relation (i=1,
2 ..., m-1), u represents the set of the be possible to value of the virtual oscillation power of single-point.In practical application, defeated by vibrating sensor
After the raw voltage signals going out obtain the virtual oscillation power of single-point, you can engine speed is calculated by formula (7).
(7), after obtaining engine speed, consider further that the method obtaining fuel consumption information.Due to engine produce thrust with turn
Square being directly proportional of speed, therefore engine power consumption is directly proportional to the cube of rotating speed, then the three of the oil consumption in the unit interval and rotating speed
Power is directly proportional:
rc=kc·n3(8) in formula, rcRepresent the oil consumption in the unit interval, be defined as rate of fuel consumption (l/s), n represents and starts
Machine rotating speed (r/min), kcIt is to characterize rcWith n3Between relation constant, be defined as oil consumption coefficient (l/s (r/min)-3).Then send out
Motivation volume of fuel consumption within a state update cycle is:
vu=rc·tu(9)
On yacht, whole q engine fuel consumption cumulative volumes within a state update cycle are:
In formula,Represent oil consumption volume within a state update cycle for i-th engine of yacht, i=1,2 ...,
q.
(8) in each state update cycle to yacht Fuel Oil Remaining vremIt is updated:
vrem=vrem-vu_sum(11)
(9), after shipowner is every time for yacht oiling, volume read-out can be informed by remote management center by strange land client terminal
Yacht status monitoring terminal device, to be updated to Fuel Oil Remaining:
vrem=vrem+vfill(12)
In formula, vfillRepresent oiling volume.
(10) after obtaining the respective rotating speed of q engine of yacht, according to formula (8), (9), (10) calculate yacht one
In the individual state update cycle, the most important condition of fuel consumption cumulative volume is the respective oil consumption coefficient of clear and definite q engineI=1,
2 ..., q.All by oil consumption coefficient, the determination of oil consumption coefficient can estimate that experiment completes, and, in yacht status monitoring eventually
After end equipment puts into operation, according to the historical data of yacht status information, oil consumption coefficient constantly can be modified.Detailed below
Describe bright oil consumption coefficient in detail to estimate the process of experiment and according to the historical data of yacht status information, oil consumption coefficient is modified
Method.
(11) carry out oil consumption coefficient to estimate to need during experiment to keep between yacht status monitoring terminal device and computer
Connect, experimentation is: execute s time for yacht and refuel and flight operations, each time oiling volume is respectively vfill_j, j=1,
2 ..., s, after refueling every time, make yacht navigate by water, by yacht status monitoring terminal device, the engine being monitored is turned therebetween
Speed uploads to computer by netting twine, until empty (in order to shorten experimental period, only adds in oiling and flight operations every time
Enter a small amount of fuel oil), by computer by added fuel bulk vfill_jIt is input in computer, as oil consumption.If jth
Secondary oiling, yacht continuous service mjIndividual tuEmpty afterwards, therebetween, i-th engine is in k-th tuRotating speed beI=1,
2 ..., q, k=1,2 ..., mj, then
In formula,Represent the oil consumption coefficient of i-th engine.Note
Then
This formula is an equation group containing s equation, q unknown number, q unknown number therein be yacht each start
The oil consumption coefficient of machine, in the case of meeting s >=q, can be derived that oil consumption coefficient or show that the least square of oil consumption coefficient is estimated
Evaluation.
(12) after yacht status monitoring terminal device puts into operation, the historical data according to yacht status information is to oil consumption
The method that coefficient is modified is: if shipowner confirms the empty in yacht fuel tank, understand before again for yacht oiling,
By strange land client terminal by the feedback of the information of empty to remote management center, remote management center is according to this yacht by upper one
Secondary empty is to the rotary speed information of intrinsic motivation during the total amount of interior institute oil during this empty and this section, knot
Close the data that oil consumption coefficient estimates that experiment obtains, be that equation group (15) increases an equation, have more experimental datas, can be to oil
Consumption coefficient is more accurately estimated, so that oil consumption coefficient is revised.Remote management center by revised oil consumption coefficient with
Parameter setting order sent along to yacht status monitoring terminal device, be allowed to oil consumption coefficient is updated.
Under certain rotating speed, the intensity of attached body vibration is the internal junction by engine itself and delivery vehicle to engine
Structure is determined, is metastable, then the relation between rotating speed oscillation power virtual with defined single-point is relative stable
, therefore, rotating speed is drawn by the virtual oscillation power of single-point according to fit correlation, and then show that oil consumption is rational.
Revolution counter in rotating speed-single-point virtual oscillation power corresponding relation matching experiment can adopt hand revolution counter,
The revolution counter carrying on platform can also be driven using yacht.Even if it should be noted that driving of yacht comprises revolution counter on platform,
Engine speed information can be shown, but because this revolution counter does not have the data-interface with the outside miscellaneous equipment of yacht, and
Only presenting to human pilot by the display that yacht drives platform expires it is impossible to be sent to remote management center by wireless network
