Abstract

The invention discloses a circuit structure and working method of an electromechanical integration device. The circuit structure includes a first CPLD, a second CPLD, a first low-voltage differential signal LVDS interface, a second low-voltage differential signal LVDS interface, a clock and Data line; the first CPLD is electrically connected to the first low-voltage differential signal LVDS interface; the second CPLD is electrically connected to the second low-voltage differential signal LVDS interface; the first low-voltage differential signal LVDS interface and the second low-voltage differential signal The LVDS interface is electrically connected through a clock line and a data line. The present invention utilizes LVDS technology to realize a small amount of 8 wires, pack and unpack data through CPLD integration technology, to transmit a large number of signals in two places separated by a certain distance, to reduce wiring complexity in mechatronics and other equipment, and at the same time It has a significant effect on the reliability of the system and reduces the troubleshooting time.

Description

technical field [0001] The invention relates to a circuit structure, in particular to a circuit structure and working method of an electromechanical integration device. Background technique [0002] With the increase of labor costs, the required automatic processing equipment is more and more complex, and with the popularization of embedded computer control, distributed control has become an inevitable trend. Therefore, in complex distributed control systems, the complexity and reliability of wiring becomes very prominent. In traditional methods, each external signal usually requires a wire to be pulled from one place (such as the main control box) to another place. [Such as on-site], if a system has hundreds or even thousands of signals, this will definitely bring great difficulties to long-distance wiring. For example, in the embroidery machine, pattern machine and shoe upper machine system, the signals arranged on site include: machine head signal, frame four-way offside...
