Description

缝纫机转速控制方法、缝纫机及存储介质 技术领域
本申请涉及缝纫机控制领域,特别是涉及缝纫机转速控制方法、缝纫机及存储介质。
背景技术
在相关技术中,为了避免缝纫机在新出厂时长时间以最高转速运行而发生故障,通常会将缝纫机的控制器内部的最高运行限速设置为低于机器允许运行的最高转速。然而在实际缝纫过程中,用户所期望设定的最高转速往往大于出厂时缝纫机的控制器内部的最高运行限速。
另外,缝纫机的控制器内部的机械参数并不允许用户直接进行调整,用户只能通过缝纫机的操作面板输入期望的最高转速。然而缝纫机控制器内部的机械参数的优先级大于用户输入的面板参数,因此在用户的缝制技能熟练度较高、所期望的最高转速较大的情况下,缝纫机内部控制器限制的最高转速并不能满足实际的缝制需要,进而导致缝纫机的缝制效率较低。
目前针对相关技术中,对于在缝纫机的最高转速无法与用户的技能熟练度不匹配的情况下,缝纫机的缝制效率较低的问题,尚未提出有效的解决方案。

在本实施例中提供了一种缝纫机转速控制方法,图1是本实施例的缝纫机转速控制方法的流程图,如图1所示,该流程包括如下步骤:
步骤S1,获取缝纫机在运行过程中以第一转速运行的时间参数占总运行时间参数的比例,其中,第一转速不低于第一阈值,时间参数包括运行时长或者运行阶段数目;
具体地,第一转速为缝纫机在一次缝纫运行阶段中达到的最高转速,且该最高转速不低于第一阈值。其中,一次缝纫运行阶段指缝纫机主轴电机开始运转到停止,中途连续运转的过程即为一次缝纫运行阶段。第一阈值在数值上与缝纫机内部设定的最高转速上限相等,例如,缝纫机内部设定的最高转速上限为4000,第一次缝纫运行阶段中缝纫机实际运行的最高转速为4000,第二次缝纫运行阶段中缝纫机实际运行的最高转速为3000,那么在进行数据的统计与计算时,第一次缝纫运行阶段的数据将会被记录,而第二次缝纫运行阶段的数据则不会统计在内。
在统计过程中,可以选择在预设时间周期内对缝纫机达到第一转速的时间进行统计,此时获取的时间参数即为缝纫机在周期内以第一转速运行的运行时长;也可以选择在一定的缝纫机运行阶段数目中,对达到过第一转速的运行阶段数目进行统计,此时获取的时间参数即为缝纫机在一定数量的运行阶段中,达到第一转速的运行阶段的数量。
步骤S2,在比例不低于第二阈值的情况下,调高缝纫机的转速上限。
具体地,在本申请的实施例中,第二阈值可以设定为30%。由于第二阈值为缝纫机的常量参数,一般是在缝纫机出厂时默认设置的,可以根据不同的服装工艺类型,在缝纫机的控制器中在一定范围内调整第二 阈值的大小。当缝纫机以第一转速运行的比例超过第二阈值时,反映出用户的缝纫技能熟练度水平较高,用户可操作的最高转速大于当前缝纫机内部限制的最高转速,因此,此时可以提高缝纫机的最高转速,以使得最高转速与用户的技能熟练度进行自适应匹配,提高缝纫机的安全性与适用性,提升缝纫机使用时的缝制效率。
通过上述步骤S1至S2,通过获取缝纫机在运行过程中以第一转速运行的时间参数占总运行时间参数的比例,其中,第一转速不低于第一阈值,时间参数包括运行时长或者运行阶段数目;在比例不低于第二阈值的情况下,调高缝纫机的转速上限,解决了相关技术中在缝纫机的最高转速无法与用户的技能熟练度不匹配的情况下,缝纫机的缝制效率较低的问题。
在其中一些实施例中,缝纫机的运行过程包括多个运行阶段,步骤S1还包括:
获取多个运行阶段的总运行时长,以及获取各运行阶段内缝纫机以第一转速运行的时长,计算缝纫机以第一转速运行的时长之和占总运行时长的比例。
具体地,以图2为例,图2展示了在三个缝纫的运行阶段中,缝纫机的转速变化曲线,缝纫机内部设定的最高转速(即第一阈值)为4000。在第一个运行阶段,缝纫机的运行总时间为T1,以第一转速运行的时间为t1;在第二个运行阶段,缝纫机的运行总时间为T2,在T2时间内用户使用的最高转速并未达到第一阈值;在第三个运行阶段,缝纫机运行的总时间为T3,以第一转速运行的时间为t2、t3。因此在图2中,最终计算得到的缝纫机以第一转速运行的时长之和占总运行时长的比例为:
在其中一些实施例中,缝纫机的运行过程包括多个运行阶段,步骤S1还包括:
获取多个运行阶段的总运行阶段数目,以及获取缝纫机以第一转速运行的目标运行阶段的数目,计算目标运行阶段的数目之和占总运行阶 段数目的比例。
具体地,以图2为例,图2展示了三个运行阶段的缝纫机转速变化曲线,缝纫机内部设定的最高转速(即第一阈值)为4000。在第一个运行阶段,用户使用缝纫机的最高转速达到了第一阈值,记为一个目标运行阶段;在第二个运行阶段,用户使用缝纫机的最高转速小于第一阈值,不计入目标运行阶段总数;在第三个运行阶段,用户使用缝纫机的最高转速达到了第一阈值,记为一个目标运行阶段。因此在图2中,最终计算得到的目标运行阶段的数目之和占总运行阶段数目的比例为:值得注意的是,一个缝纫运行阶段最多只能被记为一个目标运行阶段,例如在图2的第三个运行阶段中,有两个过程的最高转速达到了第一阈值,但这两个过程只能作为一个整体,使第三运行阶段作为一个目标运行阶段被统计与计算,不能拆分成两个目标运行阶段。
在其中一些实施例中,步骤S2还包括:
根据预设转速参数调高所述缝纫机的所述转速上限。
当S1中获取的缝纫机在运行过程中以第一转速运行的时间参数占总运行时间参数的比例大于第二阈值时,调高缝纫机的转速上限,具体的转速上限调节方法为:缝纫机的电控模块设定了一个常数作为预设转速参数Δn,例如100、200等,预设转速参数Δn可以根据实际的缝纫需要进行设置或更改。在缝纫机在运行过程中以第一转速运行的时间参数占总运行时间参数的比例大于第二阈值时,将缝纫机的最高运行转速上限提高至(N+Δn)转,其中N为调整前缝纫机的初始最高转速运行上限。
在其中一些实施例中,在步骤S1之前,还包括:
获取缝纫机的机械参数与用户参数,其中,机械参数用于控制缝纫机的实际转速上限,用户参数包括用户输入的期望转速上限;
将机械参数与用户参数进行比较,根据比较结果确定是否执行步骤S1。
具体地,机械参数是指缝纫机的控制器内部系统限制的点击最高转速参数,是机修和工厂内部管理使用的参数。用户参数是用户在缝纫机 的操作面板直接能够调整的电机最高转速,是用户根据自身的操作技能熟练度与操作习惯设置的参数。其中,机械参数的优先级是高于用户参数的,也就是说,当用户参数小于机械参数时,缝纫机实际的最高运行转速为用户参数设置的最高转速;当用户参数大于机械参数时,缝纫机实际的最高运行转速仍为机械参数,而非用户参数。
在步骤S1之前,可以将机械参数与用户参数进行比较,当用户参数小于机械参数时,缝纫机的最高转速无需调整,因此直接结束整个流程;当用户参数大于机械参数时,说明缝纫机内部限制的最高转速已经无法满足用户的技能熟练度或操作习惯的需要,因此进行S1的步骤对最高转速进行调节。
在其中一些实施例中,根据比较结果确定是否执行步骤S1包括:
在机械参数小于用户参数的情况下,执行步骤S1;或者,
在机械参数不小于用户参数的情况下,保持缝纫机当前的转速上限不变,并清除当前的数据记录,重新开始下一个缝制过程的数据记录。
具体地,在机械参数小于用户参数的情况下,说明缝纫机当前的机械参数需要进行调整,因此执行步骤S1;在机械参数不小于用户参数的情况下,说明缝纫机当前的机械参数无需调整,因此保持当前的转速上限不变,为了保证下一个缝纫运行阶段数据记录的可靠性,清楚当前的数据记录,重新开始下一个周期缝纫过程的数据记录。
在其中一些实施例中,在步骤S2之后,还包括:
调高机械参数和/或用户参数。
具体地,在计算得到的缝纫机在运行过程中以第一转速运行的时间参数占总运行时间参数的比例大于第二阈值时,还可以根据比例同时调高机械参数和用户参数的值,不仅自动改变缝纫机的实际工况,还自动对用户的设定参数进行调整,以更好地匹配用户的技能熟练度水平。
在其中一些实施例中,在步骤S2之后,还包括:
将第一转速与调高后的转速上限进行比较;
在第一转速不小于调高后的转速上限的情况下,继续执行步骤S1, 或者执行步骤S1与步骤S2。
在步骤S2调高缝纫机的转速上限后,继续对缝纫机的运行阶段进行数据统计,在调整后的转速上限仍然不小于用户操作时缝纫机达到的第一转速的情况下,继续对缝纫机在运行过程中以第一转速运行的时间参数占总运行时间参数的比例进行计算与判断,在比例大于第二阈值的情况下继续对转速上限进行调整,直至转速上限与用户的操作需要的最高转速相匹配。
如图3所示,在其中一个实施例中,图3是本申请缝纫机转速控制方法的整体流程图,包括如下步骤:
步骤S301,开机,并判断N与n的大小,其中N为缝纫机的机械参数,即内部限制的最高转速;n为缝纫机的用户参数,即用户设定的期望最高转速;
步骤S302,在n不大于N的情况下,结束流程;
步骤S303,在n大于N的情况下,统计预设的一个周期内的缝纫机转速数据,计算P值,其中一个周期可以是一定的时间周期,也可以是固定数量的运行阶段,P值为缝纫机在一个周期内的最高转速运行时间参数占比;
步骤S304,判断P值的范围区间;
步骤S305,在P值小于30%的情况下,继续进行下一个周期的数据统计,并返回步骤S303;
步骤S306,在P值大于30%的情况下,提高缝纫机的机械参数至N1;
步骤S307,判断提高后的机械参数N1与用户参数n的大小关系,在N1小于n的情况下,返回步骤S303;
步骤S308,在N1不小于n的情况下,结束流程。
