Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the embodiment of the present invention.It should be understood that this
Locate described specific embodiment and be merely to illustrate and explain the present invention embodiment, is not intended to restrict the invention embodiment.
Fig. 1 is the flow chart of the method for determining craning weight of same according to an embodiment of the invention.This method includes following
Step:
Step S110, the initial hoist value of the multiple initial calculations of acquisition time sequentially.Initial hoist value is i.e. using existing
The hoist value for thering is technology to obtain.For example, the input torques such as length of boom, angle, pressure sensor real-time parameter can be limited
Thus initial hoist value is calculated using the input as BP neural network in device.Initial hoist value can also utilize the prior art
In other methods determine.
Step S120, according to current time closest to predetermined number initial hoist value, determine the crane
Current working status.In the crane course of work, each moment can be successively obtained with time sequencing and certain time interval
Initial hoist value.In the current working status for determining crane, according to apart from current time nearest predetermined number just
Beginning hoist value, being capable of accurate judgement current working status.For crane, working condition generally comprises steady state, rises
Hook-shaped state, off the hook state.Steady state, that is, crane hooks up before rear, off the hook normal movement or flexible state in the sky.
Step S130 determines the current hoist value of the crane according to the current working status.
Under steady state, theoretically the hoist of crane should be remained unchanged, but hoist may be due to various
Factor and jump, especially for can carry out with the crane for carrying Telescopic, cantilever crane, wirerope etc. when band carries flexible
Frictional force change dramatically occurs, cause hoist jump serious.In this case, if by hoist value determining in the prior art
It will be unfavorable for the security control of crane as craning weight of same.The hoist value that thus present invention determines the prior art is as just
Beginning hoist value, and determine based on this current working status of crane, and further determine that according to current working status final
Current hoist value.Fuzzy processing is carried out to the hoist obtained in the crane course of work as a result, is jumped so as to eliminate hoist
Become, to obtain accurate current hoist value.
Fig. 2 is the flow chart of the method for determining craning weight of same according to another embodiment of the present invention.As shown in Fig. 2, root
Determine that current working status may include following steps according to the initial hoist value of the predetermined number:
Step S202 determines that the change degree of the initial hoist value of the predetermined number, the change degree indicate the lifting
The hoist variation degree of machine.
Step S203 determines the current working status of the crane according to the change degree.
Fig. 3 is the flow chart of the process for determining crane current working status middle according to one preferred embodiment of the present invention.Such as
Shown in Fig. 3, determine that the process of current working status can preferably include following steps:
Step S301, the determining initial associated a reference value of hoist value with predetermined number.A reference value can be and predetermined
Several initial associated arbitrary values of hoist value, such as any one value that can be chosen in the predetermined sensitive initial value are made
On the basis of be worth.
In the present invention, a reference value is preferably intermediate value, average value or the institute of the initial hoist value of the predetermined number
State the average value when initial baseline value of predetermined number is arranged by the time sequencing positioned at one of middle or both.Example
Such as, the initial hoist value of predetermined number can choose 9 values nearest from current time, as shown in figure 5, can successively be labeled as
M1、M2……M9, at this point, M can be chosen5On the basis of be worth.If choosing 8 values nearest from current time (can be denoted as M according to production1、
M2……M8) initial value as predetermined number, a reference value can be M3And M4Average value.In addition, a reference value can also be pre-
Determine the average value or intermediate value of a reference value of number.Those skilled in the art can select Else Rule to determine a reference value, such as
When predetermined number is 9, M can be2And M8Average value.
Step S302 determines variation of each relative to a reference value in the initial hoist value of the predetermined number
Degree.
It can determine that each is relative to the benchmark in the initial hoist value of the predetermined number according to following equation one
The change degree of value:
Equation one:
Wherein, diIt is i-th of initial hoist value in the initial hoist value of the predetermined number relative to a reference value
Change degree, MiFor described i-th initial hoist value, M is a reference value.
Step S303 determines in the initial hoist value of the predetermined number that the change degree relative to a reference value is greater than
First number of predetermined value.For example, the predetermined value can be 0.5, when change degree is greater than 0.5, it is believed that the hoist of crane
It changes greatly.The statistics available number conduct in the initial hoist value of predetermined number, relative to the change degree of a reference value greater than 0.5
First number, and the current working status is determined according to described first number.
Determine that the process of current working status can preferably comprise according to first number:
Step S304, judges whether first number that current time determines is greater than predetermined number.
Step S305 makes n that 1, n be added to indicate first number until current time when first number is greater than predetermined number
Greater than first number of predetermined number.
Step S306 makes m that 1, m be added to indicate until current time when first number is less than or equal to predetermined number, the
One number is the predetermined number second number below.
It is illustrated below.Until near current time, the ti that t1, t2 is calculated as to the sampling instant of initial hoist value ...,
Ti indicates current time, and t1 indicates the first moment sampled to initial hoist value, with 9 values nearest apart from current time
As the initial hoist value of the predetermined number, predetermined number value is 7.Assuming that current time was the 17th moment (i.e. i=17),
It is delayed until the 9th moment, the current working status at current time can be determined according to 9 initial hoist values.Assuming that when from the 9th
Until quarter plays current time, in the initial hoist value of 9 of each moment number of the change degree greater than 0.5 be followed successively by 5,4,6,8,
9,7,6,8,9.Then after the preceding moment executes step S304-S306, m=5, n=4.That is, making a reservation for a until current time
In several initial hoist values, the number relative to the change degree of a reference value greater than 0.5 have 4 times be more than 7, have 5 times without super
Cross 7.
The value of the predetermined number will affect the delay that can accurately determine current hoist, and those skilled in the art are in reality
When applying the present invention, the value of predetermined number can be determined as the case may be.
Step S307, according to being determined with first number and the associated state subordinating degree function of second number
The current smoothness of crane.Current smoothness indicates that current crane is intended to the degree of steady state, it may for instance be considered that
When current smoothness is greater than 0.5, current working status is steady state.
In a preferred embodiment, the state subordinating degree function is as shown in following equation two:
Equation two:
Wherein, n is first number, and m is second number, and P is the smoothness.
After determining current smoothness, current working status further can be determined according to current smoothness.Specifically may include as
Lower step:
Step S308, judges whether current smoothness is greater than predetermined smoothness.
Step S309 can determine that current working status is steady state if current smoothness is greater than predetermined smoothness.
Step S310, if current smoothness is less than or equal to predetermined smoothness, it is believed that current working status is to hook up
Or off the hook state.
Step S311 resets m, n when determining current working status is steady state.
When the current working status of crane is determined, final current hoist can be determined according to current working status.Ginseng
Fig. 2 is examined, determines that current hoist may include following steps according to current working status:
Step S204 judges whether current working status is steady state.
Step S205, if current working status is steady state, can further determine that and current time closest to the
The average value of the initial hoist value of one predetermined number.
Step S206, judge current initial hoist value relative to the average value error whether in predictive error range
It is interior.
Step S207, if current initial hoist value relative to the average value error in predictive error, can will
The average value is determined as current hoist.When determining current working status is steady state, the actual working state of crane
It may be to remain steady state, it is also possible to start to be turned from steady state to the state that hooks up or off the hook state at current time
It changes.Therefore, if current initial hoist value relative to the error of the average value is within predictive error, it is believed that crane
It is still run to current time with steady state.And if current initial hoist relative to the error of the average value has been more than pre-
When determining error, it is believed that current working status is converted to the state of hooking up or off the hook state by steady state before.For example, the
One predetermined number can be 20, and predictive error can be 8%, if the initial hoist value at current time is relative to from current time
The error of the average value of the initial hoist value of nearest 20 is 9%, then it is believed that actual current working status is by before
Steady state is converted to the state of hooking up or off the hook state.
In step S208, if current working status is not steady state, it is believed that current working status is to hook up
State or off the hook state.
In step S209, if current working status be hook up state or off the hook state, can will current time just
Beginning hoist value is determined as current hoist value.Hook up or off the hook state under, it is normal that variation, which occurs, in craning weight of same, therefore can
Current initial hoist value is determined as current hoist value.Current initial hoist value can also be further processed to make
For current hoist value.For example, if can use most when current initial hoist value is excessive with respect to the variation of the initial hoist value of last moment
The average value at nearly two moment is as current hoist value.
