Abstract
The invention provides a data acquisition method and system. Rotational speed of a wire guide wheel is used to indicate start-stop states of a production nose; if greater than a preset threshold, the rotational speed indicates a normal start state of the production nose; if less than the preset threshold, the rotational speed indicates a stop state of the production nose. A processor continuously acquires the rotational speed of the wire guide wheel; if the rotational speed abruptly changes from being greater than the preset threshold to being less than the preset threshold, a stop moment is recorded; if the rotational speed abruptly changes from being less than the preset threshold to being greater than the preset threshold, a start moment is recorded; a duration between the stop moment and the start moment serves as a fault time. The data acquisition method and system allows the fault time of the production nose to be automatically calculated; compared with the traditional art of manually recording the start-stop states, the data acquisition method and system has the advantage that calculation of the fault time of the production nose is more accurate and more efficient.

As shown in Figure 1, the invention provides a kind of data-acquisition system, described system comprises:
The speed pickup 200 be connected with the line guide wheel 100 producing head, described speed pickup 200 is for gathering the velocity information of described line guide wheel;
The analog to digital converter 300 be connected with described speed pickup 200, described analog to digital converter 300 is converted to the velocity of rotation of the line guide wheel of digital quantity for the velocity information of the described line guide wheel by analog quantity;
The processor 400 be connected with described analog to digital converter.
At enameled wire in process of production, when producing head and being in open state, line guide wheel 100 must rotate with speed along with line, when producing head and shutting down because of a variety of causes, and the inevitable stall simultaneously of line guide wheel 100; Therefore whether the present invention operates as the start-stop foundation of producing head using line guide wheel 100.In order to judge whether line guide wheel 100 operates, speed pickup 200 is arranged on line guide wheel 100, speed pickup 200 is utilized to gather the velocity information of line guide wheel, the velocity information of line guide wheel 100 is analog quantity informations, conveniently subsequent processor 400 carries out data processing, utilizes analog to digital converter 300 velocity information of line guide wheel 100 to be converted to the velocity of rotation of the line guide wheel 100 of digital quantity.

As shown in Figure 2, the invention provides a kind of data capture method, comprising:
Step S101: determine the shutdown moment of producing head, namely the velocity of rotation obtaining described line guide wheel from described analog to digital converter is continued, when in adjacent two moment, the velocity of rotation corresponding with previous moment is greater than predetermined threshold value, and the velocity of rotation corresponding with a rear moment is less than described predetermined threshold value, then confirm that described production head is in stopped status in a rear moment, the record shutdown moment now, wherein, described velocity of rotation is that described AD converter obtains after analog to digital conversion according to the velocity information that described speed pickup gathers;
In theory, when producing head and being in open state, line guide wheel 100 must rotate with speed along with line, when producing head and shutting down because of parts reason, the inevitable stall simultaneously of line guide wheel 100, but due to inertia reason, after production head starts running, the velocity of rotation of line guide wheel 100 should be the process risen gradually, until reach the permanent speed producing head, when after the stall of production head, line guide wheel 100 is inevitable is decreased to zero gradually by permanent speed, therefore known produce head start running and start shut down initial time section in, the velocity of rotation of line guide wheel can not be synchronous with production head, so directly judge that whether the velocity of rotation of line guide wheel 100 is zero judge whether production head stops state, have certain time delay, namely produce head to stop in the T1 moment, line guide wheel be also in rotary state due to inertia, be just zero in the velocity of rotation of T2 moment line guide wheel, the shutdown moment of producing head is in theory T1, but due to inertia reason, measuring the shutdown moment obtained is T2, now the time of T2-T1 is just for shutting down the error in moment.
Therefore do not adopt null value as the basis for estimation of producing head start-stop in the present invention, but arrange a predetermined threshold value, this predetermined threshold value is a value in the middle of zero to permanent speed, and concrete can determine according to actual conditions, does not limit at this.When the velocity of rotation of line guide wheel 100 is greater than predetermined threshold value; represent that line guide wheel 100 operates; produce the open state that head is in normal work, represent that line guide wheel shuts down when the velocity of rotation of line guide wheel 100 is less than predetermined threshold value, produce head and be in stopped status.Adopt the mode of predetermined threshold value to reduce error, improve the accuracy of fault-time further.

When velocity of rotation by velocity of rotation be less than predetermined threshold value sport velocity of rotation be greater than predetermined threshold value time, then illustrate produce head enter open state by stopped status, now record start the moment, this start moment is the fault end time;
Step S103: using the time period between described shutdown moment and described start moment as fault-time.
The present invention can calculate the fault-time of producing head automatically, substantially increases to calculate to produce head accuracy and efficiency fault-time for traditional hand-kept start-stop state.
As shown in Figure 3, after obtaining fault-time, in order to the loss amount obtained between age at failure needs to be further processed:
Step S201: obtain the permanent speed producing head;
Acquisition process can comprise two kinds of modes: the first: from default Specifications Database, obtain the permanent speed corresponding with described production head; The second: gather and record permanent speed when described production head is in open state.
Before according to first kind of way, need in default Specifications Database, to store the permanent speed corresponding with this production head in advance, then can utilize in this step and obtain from default Specifications Database, the manner more for convenience.
The permanent speed producing head at the operational process Real-time Collection producing head is needed in the second way, add Software for Design difficulty but can produce the running speed of head in this operational process exactly compared with first kind of way, real-time is better.
Step S202: described permanent speed was multiplied with described fault-time and obtains enameled wire lost length.
Be multiplied with the permanent speed producing head by the fault-time obtained in step S103, the enameled wire length of losing between age at failure can be obtained.
Step S203: obtain from described default Specifications Database and the enameled wire density of described production head and enameled wire diameter; In described default Specifications Database, the enameled wire density corresponding with described production head and enameled wire diameter was stored in advance before this step.
Step S204: calculate enameled wire bodies lost weight by described enameled wire density, described enameled wire diameter and described enameled wire lost length.
Concrete, by described enameled wire diameter and described enameled wire lost length by volume formulae discovery obtain enameled wire and lose volume; Described enameled wire loss volume is multiplied with described enameled wire density and obtains described enameled wire bodies lost weight.
