Embodiment Construction

[0032] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used herein in the description of the present invention is only for the purpose of describing specific embodiments, and is not intended to limit the present invention.

[0034] The present invention adopts an isolated transmission circuit and an isolated encoder system including the isolated transmission circuit. The purpose is to adopt a fully isolated manner so that the photoelectric encoder and each unit of the DSP main control unit have no direct electrical relationship. When a lightning strike occurs, a direct disc...

Abstract

The invention discloses an isolated transmission circuit and an isolated encoder system, which are used to solve the problem of sewing machine failure in thunderstorm season. The isolated transmission circuit includes a high-speed optocoupler module, which is used to isolate and transmit the first signal and the second signal of the photoelectric encoder to the DSP main control unit; a low-speed optocoupler module, which is used to isolate and transmit the third signal of the photoelectric encoder to the DSP main control unit. The isolated encoder system includes: an isolated multi-channel power supply, a photoelectric encoder, an isolated transmission circuit and a DSP main control unit, which are used to collect and calculate signals sent by the photoelectric encoder in real time. The present invention adopts a fully isolated manner to improve the anti-lightning strike performance of the controller of the sewing machine and reduce the failure probability of the sewing machine.

Description

technical field [0001] The invention relates to the technical field of sewing machine control, in particular to an isolated transmission circuit and an isolated encoder system. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. With the development of technology and higher and higher requirements for sewing, new and higher requirements have been put forward for the control accuracy and auxiliary functions of sewing machines. Therefore, many electronic components and electronic control systems have been introduced, such as photoelectric encoders, It is used to detect the position of the motor, and it is used more and more in high-end sewing machines. However, the use of photoelectric encoders to detect the position of the motor still has the following problems: [0003] (1) In the thunderstorm season, the photoelectric ...
