Problems solved by technology

[0004] The above action units cannot be used in the calculation of machine sewing time, because the calculation of machine sewing time is affected by various factors such as machine type, machine speed, fabric type, sewing difficulty, and stop mode. It is impossible to accurately determine the standard man-hours for sewing

Embodiment Construction

[0035] Embodiments of the present invention provide a method and device for determining standard sewing hours, which are used to accurately determine standard sewing hours.

[0036] As a standard work-hour unit, the speed of digital cameras is usually 32 frames per second. Therefore, the minimum time unit is calculated as 1 / 32=0.00000868 hours. Obviously, such a time cannot be used in practical applications. Therefore, 0.00001 hour is recorded as 1TMU (Time Measurement Unit, time measurement unit). Therefore, 1 hour = 100000TMU, 1 minute = 1667TMU, and 1 second = 27.78TMU.

[0037] see figure 1 , an embodiment of a method for determining a standard sewing man-hour provided by an embodiment of the present invention specifically includes:

[0038] 101. Determine the sewing machine speed according to the performance of the sewing machine used;

[0039] In this embodiment, the rotational speed varies according to different sewing machines, and the rotational speed of the sewing ...

Abstract

The invention discloses a standard sewing time determination method and device applied to precisely determine standard sewing time. The method includes: determining sewing machine speed according to the performance of a sewing machine in service; determining stitch length of the sewing machine according to sewing requirements; acquiring fastest sewing time per centimeter according to the sewing machine speed and the stitch length of the sewing machine by means of a first calculation rule; determining a sewing machine controlled allowance coefficient according to the fastest sewing time per centimeter; determining a sewing difficulty level floating coefficient and sewing stop difficulty level allowance according to sewing difficulty; acquiring standard sewing time according to the sewing machine speed, the sewing machine stitch length, the sewing machine controlled allowance coefficient, the sewing difficulty level floating coefficient and the sewing stop difficulty level allowance by means of a second calculation rule. Influences caused by coaction of the multiple factors such as the machine speed, cloth type, sewing difficulty and stop mode are eliminated, and accordingly, the standard sewing time is determined precisely.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of statistical standard man-hours, in particular to a method and device for determining standard man-hours of sewing. Background technique [0002] Standard man-hours are the man-hours required for a process in a standard working environment. [0003] In order to obtain accurate standard man-hours, the existing scheme can split specific work tasks into several work units according to predetermined rules, and determine the standard man-hours of work tasks by counting the number of work units and the time spent. [0004] The above action units cannot be used in the calculation of machine sewing time, because the calculation of machine sewing time is affected by various factors such as machine type, machine speed, fabric type, sewing difficulty, and stop mode. It is impossible to accurately determine the standard man-hours for sewing. Contents of the invention [0005] Embodiments ...
