The main controller serves as the data transmission starting point, a needle selection assembly serves as the data transmission terminal point, intermediate links are achieved completely through digital circuit hardware, data transmission paths are shortened on the premise that system complexity is not increased, and reliability and stability of the control system are improved.

Description

technical field [0001] The invention relates to a control method of an electronic jacquard control system, in particular to a control method of an electronic jacquard control system based on multi-loop data transmission. Background technique [0002] During the development of the electronic jacquard machine in recent years, many new processes and technologies have emerged, but at the same time, the market has higher requirements for its technical performance and cost-effectiveness, especially for high-speed machines in the past one or two years. , large needle count, high warp density, etc., the market demand is more prosperous. Therefore, it is particularly important to improve the technical performance and working stability of the jacquard machine itself. The electronic jacquard machine is a high-tech product that is highly integrated and unified in machinery, electronics and software. It has the characteristics of complex electromagnetic environment for operation, huge n...

Problems solved by technology

Therefore, the data link is too long, and the probability of being interfered is very high. In practical engineering applications, data is often interfered, and it is impossible to find intractable diseases;

[0008] (2) In the transmission link, there is a connector for every 8 pins, so there are many connection points, and a poor contact at one point will cause all subsequent data to be destroyed

A large number of single-chip microcomputers work intensively for a long time in a complex electromagnetic environment, high temperature, and high humidity environment, and their stability and reliability are greatly reduced;

[0014] (3) Data storage can not meet the demand: this scheme adopts the method of storing data first and then working, and the single-chip microcomputer used in this system can only be a small-package chip, and it is impossible to use a larger or even larger chip due to size and cost constraints. package, and the storage unit capacity inside the small package microcontroller is generally very small, and the data storage capacity is limited.

However, this scheme adopts multi-level embedded system control, which increases the complexity of software and hardware of the system and increases the difficulty of maintenance;

[0020] 3) For multi-level embedded system control, each group must increase its own storage space, so the cost of the entire system is high

[0021] At present, all improvements made to the stability and reliability of data transmission are basically limited to the above-mentioned control methods of hierarchical transmission and packet transmission
