Description

ti? 15 253 25 3G 536 801 pen speed gives an etiiiräekiig precision in assessing the function of the starter meter, at least in certain circumstances.

SUMMARY OF THE INVENTION The object of the present invention is therefore to provide a solution which eliminates the need to prepare it, thereby enabling a more accurate diagnosis of a metered electrical starter.

According to one aspect of the invention, the object is achieved by the system described in the preamble, the system comprising a tent temperature measuring means configured to measure at least one temperature related temperature. Preeessern is when kentigure rad ätt eestärnnte status indicator on further basis of the at »minstete a measured tent temperature. Ben measured tent temperature indicates when at least one of an egg temperature in the dry pressure meter, a cooling temperature consumes the dry burning meter, a temperature outside temperature of the dry burning meter a petteri temperature. Furthermore, the preeesser is specifically configured to determine the status indicator on the basis of the at least one measured temperature, whereby the status indicator is determined according to the true value: C RPM + ivrrr) u / Nzrrg where C is a directional tenant, RPM indicates a measured starting value. , U indicates a measured supply voltage at the start test, Nt fi) indicates a speed set at the at least one temperature (T), the NET) indicates a speed save set at the atmirtstene a temperature (T).

This system is drastic, since mitigation changes (for example due to seasonal growths and free radicals in the tooth) are weighed into the diurnal process in a natural and adequate manner. The viscosity of the water in the firing meter varies considerably with the temperature, which in turn is reflected in the step-measured speed.

According to one embodiment of the embodiment of the invention, the processor is configured to look at the status indicator a first value if the start of the starter is considered to be aoeptapei, while a second value if the starter is not considered to function properly. Specifically, the status indicator indicates that the first value of the measured supply voltage exceeds a voltage threshold and that the measured speed exceeds a speed threshold. That is to say, a properly functioning starting meter is expected to result in at least a certain meter speed of the pre-combustion meter when the starting counter is subjected to a certain supply voltage, according to another embodiment of it when the aspect of the invention is preeessively configured to additionally adaptively the at least a measured temperature so that at a tdrnàiiandevis ndg measured temperature for a relatively long time reached rnatningspänning must be metsvar by a tipprnätt varvtai exceeding varvtaistrdskein tär that the adaptive tiiviii- karet should be considered tipptyiiiitet the fipptiiiiit. On the other hand, at a temperature measured separately, a relatively high measured supply voltage can correspond to a measured speed just above the speed limit, whereby the adaptive biviiikeret is considered to be the status indicator titled to the first value. Thus, the influence of temperature on the starting motor's conditions for heavy, rather adaptive piviiikeret is with the reverse inversion of preportionation to the measured temperature is taken into account.

According to yet another embodiment of the invention when the aspect of the invention is configured to give the status indicator a third value representing that the function of the starting meter cannot be determined as the measured intake voltage is less than the voltage threshold. Gm the supply voltage is eaten tär iäg 'iO '35 2G 25 3G 536 801 one can namely not draw any siutsats neträttaitde em the fact that the tdridränningsmatern does not start pears on am the starting motor is teiakt, after dm tetet depends on something else, the season etiii ~ proper battery storage.

According to a further embodiment, when the aspect of thawing is metered, it is configured to feed the technical forces during a network interview, it is pre-configured to distribute the measured technical parameters over the feed interface. The meter is also configured to determine the status indicator on the basis of a rotational value of the supply voltage to the starting meter during the feeding interval and a co-value of the speed below the pressure monitor during the measuring interval. In addition, the temperature supply means is also configured to meet the temperature of at least one temperature during a measurement interval and the processor is also configured to co-value the measured temperature over the measurement interval. The presser is already configured to utilize the value-assisted temperature in the tuning of the status indicator. A careful consideration of co-values is tördei-like, since the mdmentana values for rattungsstänning, where a temperature can be tiittäiiigt misleading for the tactical töräiianden. It can also be tedious to observe other parities, such as a most closely measured supply voltage to the starter note during a compression series.

Yet another dehydration storm of the when the aspect of the invention is assumed to be the dehydration burning meter may be of a certain type of at least two identical types of mites. Preeesssrn is already configured to determine the status indicator on a further basis of the mder type in terdenet. If the engine types are assumed to be associated with such conditions as the starter tractor's function, the starting point from the input to the actuator type can thus be specified parameters for the threshing value chosen for the diagnosis of the starter motor.

In yet another aspect of the invention, the object is achieved by the method described above, wherein at least one temperature measured is measured, but the status indicator is further determined on the basis of the at least one measured temperature, at least one of which indicates the return. an inertia temperature in the drywall, an ityivatertemperature in the drywall, a maturity temperature in the drywall. Furthermore, the status indicator is determined on the basis of the measured temperature according to the relationship: C naive: Where; J u / rvzrr; where C is a dimensional characteristic, RPM indicates a measured speed at a starting torque, U indicates a measured supply voltage at the starting torque, NMT) indicates a speed set at the at least one turn (T), the NZ-width indicates a speed atrninstene a temperature (F).

The advantages of this method, as well as of the drawn-out drying terms thereof, are apparent from the discussion of the tail with reference to the drying system. to control the steps according to the above method when the said program is run on a dater. The Üatarn can in turn be represented by a control unit in the terdenet, a dartiii anstuteit diagnostic unit, a surtpiatta, a smartptiene ete.

According to yet another aspect of the invention, the object is achieved by means of a computer keyboard medium with a program stored thereon, where the program is adapted to cause a computer to control the steps according to the tail method. 1G 20 25 30 536 801 BRIEF DESCRIPTION OF THE DRAWINGS The following tipptirtning kenwrner now that törkiaras closer rne- cieist titiöringsterrner, viika described sern exernpei, een rned nanvisning tiii the attached drawings.

Figure 1 shows a seniority figure of a proposed sister. Figure 1a-b shows the burrs which illustrate only the status indicator can be shown as a result of the invention. The figure shows a degree of variability illustrated by the method indicator.

DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION We refer, respectively, to Figure 1 which shows a senernatic embodiment of a sister according to the invention for the diagnosis of an electric starter, 119. The electrite starter is shown in FIG. the start meter 11Û is configured to start the t ~G training meter tZG. The electric starter 119 is in turn powered by a battery 135.

The dry system comprises ntatergan 130 een 146, tern »peraturnriätningsergan 1513 een en precesser dense. Iviäterganen 136 een 146 are configured to obtain technical stars related to torciertei.

The temperature at "i" can, for example, refer to an irrigation temperature at the taraenet, a property temperature in the river, a cooling water tripe rate, a temperature temperature, a starter temperature below one! egg and night rider nature. It is tedious to register more than one temperature, since this does not make an assessment of whether the terdonet kaiistartas (normal temperatures are essentially - again tica), verrnstartas (oiietemperatiren i metern een en ityivat »tenternneraturen ettersnivst intivst).

Alternatively, the network interval may be adantatively cepniat tiit one after three compression cycles nes törnranningsrneterit 129, so that the network interview represents a new number of itampression cycles.

A typical kentnreseionseykei is around 15 rns pliers, Since an alternative to a pure rterterieivartsnirting of the RPM speed, the processor close to such a taii can be kentigarareri to register a maximum speed during a nuclear compression cycle. The starting performance is namely shown to be low at the speed when it is taken.

Similarly, the ignition temperature measuring means is tightly configured to measure the temperature at a temperature "i" during a sealing interval. If so, the fat is, of course, the precursor to the fact that the temperature is at least one of the temperatures "t" above the water of the net, one utilizes at least one of the atomic values of the bit value temperature when determining the state indicator S.

It may further be advantageous to adapt the diagnostic procedure performed by the processor 166 depending on seasonal growth rates. Ex »entpeivis, a temperature adjustment can be made in two steps (sera rnarivinter), in ttera steps (sasem below ~ 25 ° C, rnettan 25” C een -290 C, rneitan ~ 2Û ° C een -tÛÛ C, rnettan Itt?

The burr shows an average rated voltage Uavg look at the starter tower "ittlt along the nerisenteiia axis one a generously rotated RPtvtav-g nes tërtaränntngsrneterrw" E26 close to the vertical axis.

It is tedious to calculate the status indicator S the continuous genre to equate a measured speed RPM with an expected speed one to apply at least the level of efficiency (for example, a company level representing an acceptable level of measurement GK it a second level equivalent to a level). ritrr; Urnzrr; S 1: 2: where RPM indicates a measured speed at a starting torque search, T indicates a measured temperature (eäeern en ambientetern »nerattir at terdenet), U indicates a measured supply voltage at atarttdradket, NHT) indicates a speed taisetteet at temperature T, een NÄT) indicates a speed ice parameter at temperature T.

To illustrate this, we refer to Figure Eb, where a second graph 'iO 15 20 25 3G 536 801 shows only the prdeesearn close) tiiídeiar statueindikatnrn S. in the same way as Figure Qa. the graph here shows a genamenittiig ntatningespänning tjat-g titt etartmetern ttt) iänge den harisdnteiia axein den ett ge ~ npmsnittiigt varvtai RPivia-g tips tdrpränningernetdrn tätt iänga den vertikaia axein. i Figure One assumes a measured temperature T na a value TZ> Tt.

The fact that the adaptive piviiikpret is inverted preportieneiit to the measured temperature T means that, at a higher temperature "i". If a given supply voltage Uavg is required, a few revolutions RPtt / iatfg are required in order for the starting meter to be considered to be atzpeptapei (the status indicator S must tiiidetae the first value OK).

In order to further tighten the speed requirement at an increased temperature T, a second supply voltage Ubiz, at a higher temperature TZ> Tt, can also be given a lower value, that is to say Um: <Ubu. where Uefa 72 Unt.

The processor is tightly defined by the third adaptive pulse on the basis of the measured temperature T so that, at a three degree high measured temperature TE, a relatively measured supply voltage Uavg must measure by a measured varvtai varptai. shall be considered to be upptyiit the status indicator S tiiideias the first value OK.

At a temperature measured E12, there is therefore a precursor 166 with the torque configured to indicate the status indicator S, so that a relatively closely measured supply blockage Uavg can be answered by a measured speed just above the speed range, the RP is considered to be RP; upptyiit den statueindikatprn S tiiideåae the first value GK.

If the measured supply voltage Uavg is less than the voltage swamp Urk, it is, as mentioned above, possible to attenuate etartmdtprne function. Accordingly, an invention of the invention is not construed as having a state-of-the-art knowledge of the state indicator S a third quarter UNDEF representing that the function of the starter can not be determined by an invention of the invention......................
