The startup multiple of machine, IeIndicate the rated current of motor.In practical application, it is different to start multiple for different types of motor.It is practical
In, the functional relation can be based on and build above-mentioned computation model (for example, first computation model), and then by computation model
Processing obtains the startup time of motor.
In a kind of implementation of the embodiment of the present invention, heating time constant can be determined by following functional relation：
tfr(n+1)=tfr(n)·tqd(n)/tqd(n-1)；Wherein, tfr(n+1)For the heating time constant after (n+1)th startup of motor, tfr(n)For
Heating time constant after the startup of motor n-th, tqd(n)Start time, t for motor n-thqd(n-1)For motor, (n-1) is secondary opens
The dynamic time.In practical application, the functional relation can be based on and build above-mentioned computation model (for example, second above-mentioned computation model),
And then obtain the startup time of motor by the processing of computation model.
In a kind of implementation of the embodiment of the present invention, the trip time can be determined by following functional relation：tk(n+1)=
tk(n)+(tk(n)-tk(n-1))；Wherein, tk(n+1)For (n+1)th trip time of switch, tk(n)To switch the trip time of n-th,
tk(n-1)For (n-1)th trip time of switch.In practical application, the functional relation can be based on and build above-mentioned computation model (ratio
Such as, the second above-mentioned computation model), and then obtain the trip time of motor by the processing of computation model.It should be noted that
Above-mentioned each functional relation is merely illustrative.In practical application, above-mentioned three kinds of functional relations can be based on and build a kind of computation model, in turn
One of startup time of motor, heating time constant, trip time or multinomial are obtained by the processing of the computation model.
Can also be that (i.e. n-th opens one or more variables on the basis of above-mentioned functional relation in other implementations
When heating time constant, (n-1)th trip time after dynamic time, (n-1)th startup time, n-th startup, n-th trip
Between one of or it is multinomial) increase weight coefficient, by the weight coefficient can adjust functional relation in relevant variable to result of calculation
The influence of (heating time constant, (n+1)th trip time after i.e. (n+1)th time startup time, (n+1)th startup).The weight
Coefficient can be arranged according to actual needs, can be set as fixed value, can also be set as variable value, can dynamically adjust, also can static configuration
(for example, manual setting or update etc.).
For example, when determining the startup time, following functional relation also can be used：tqd(n+1)=a1tqd(n)+(a1tqd(n)-
a2tqd(n-1))/e, wherein a1、a2Respectively tqd(n)、tqd(n-1)Weight coefficient, by reseting a1、a2Value it is adjustable
tqd(n)、tqd(n-1)To tqd(n+1)Influence.Similarly, can also increase in this way when determining heating time constant, trip time
If corresponding weight coefficient, to adjust t by adjusting the value of each weight coefficientfr(n)、tqd(n)、tqd(n-1)To tfr(n+1)Shadow
Ring, and/or adjust tk(n)、tk(n-1)To tk(n+1)Influence.
The case where for needing to control multiple motors, the above method can also include：The weight that computation model need to be used
Coefficient is associated with the device parameter of motor, establishes corresponding mapping table, and the mapping table includes each weight coefficient
The value of corresponding distinct device parameter.Under this scene, it can also start in acquisition n-th and stop parameter and (n-1)th startup
Stop acquiring the device parameter of motor together when parameter.Start the process for stopping parameter at this point, being determined in step 102 (n+1)th time
It can realize in the following way：Corresponding weight coefficient is read from the mapping table pre-established according to device parameter,
It calls the computation model to start the weight coefficient, n-th to stop parameter and start for (n-1)th time to stop at parameter
Reason, obtain the motor (n+1)th time start stopping parameter.
It, can be by the weight system of computation model in a kind of realization method, such as when needing to control same type of multiple motors
Number is associated with motor mark (for example, device number of motor), establishes corresponding mapping table, which includes each power
Weight coefficient corresponds to the value of different motor marks, which can be one-to-one, one-to-many, many-one etc..Another realization side
In formula, such as when needing to control different types of multiple motors, the weight coefficient of computation model can be associated with motor model, be built
Corresponding mapping table is found, which includes the value that each weight coefficient corresponds to different motor models, which can
To be one-to-one, one-to-many, many-one etc..
In practical application, can correspond to respectively the first computation model, the second computation model, third computation model establish it is different
Mapping table can also define weight coefficient, the second calculating mould of the first computation model respectively in same mapping relation table
The correspondence or incidence relation of the device parameter of the weight coefficient of type, the weight coefficient of third computation model and motor.
It should be noted that when number of starts n is 1, it is desirable advance to stop parameter for n-1 0, at this time (n-1)th startup
The specific value of the fixed value of setting, the fixed value can be preset according to actual needs, and empirical value may be used, and can also be adopted
With the other values for meeting computation model computation rule.For different motors, which can also be arranged different values.Specifically answer
In, the startup for the first time which may be embodied in motor stops in parameter (for example, by managing before motor starts for the first time
Member's setting, or be previously written in the allocation list of motor control assembly with default value), it can also be used as the weight system of computation model
Number, is configured in the form of mapping table.That is, be pre-configured with comprising the fixed value correspond to distinct device parameter (for example,
The device number etc. of motor model, motor) value mapping table, calculate the 2nd time start stop parameter when, this can be read
(n-1)th time of corresponding current collected device parameter starts the value for stopping parameter in mapping table, true using the value
Fixed 2nd startup stops parameter and other modes also in addition to this can be used, in this regard, not being restricted herein.
