Problems solved by technology

For the electronic jacquard machine with a large number of needles, the amount of data per weft X is large, the first method completely uses serial shift transmission, the speed is too slow, and the probability of error is high; the second method uses data shunting, which reduces serial transmission. The amount of data shifted by rows, but the data of each latitude must first be shunted to m I / O interface boards, which has no obvious effect on improving the speed

Abstract

The invention discloses a device and a method for transmitting data of an electronic jacquard machine, and belongs to the technical field of control for jacquard machines. The device comprises a master controller, m lower computer CPUs (central processing units), m driving chips, mXn shift registers and m memories. When the device works, N data of an integral pattern are respectively transmitted to the memories of the m lower computer CPUs at first and then are transmitted to an electromagnetic driver board of the jacquard machine via the shift registers in a unified manner. An electronic jacquard machine with N needles is changed into the jacquard machine with N / m needles, transmission time is shortened to be 1 / m of original transmission time, work efficiency is greatly improved, and problems of high quantity of data of an existing electronic jacquard machine with high quantity of needles and slow speed are solved. In addition, data error rate can be minimized owing to data transmission and detection functions of the lower computer CPUs, and jacquard efficiency of the jacquard machine is improved.

Description

technical field [0001] The invention relates to a jacquard machine control technology, in particular to an electronic jacquard machine data transmission device and method. Background technique [0002] The time and accuracy of the control interface of the electronic jacquard machine to transmit the pattern data of each weft to the electromagnetic jacquard device is the key to determine the working speed and efficiency of the electronic jacquard machine. There are two methods of traditional electronic jacquard machine control transfer interface to transmit data, one is to serially shift and transmit X data of each weft to each electromagnetic drive board of the electromagnetic jacquard device, and the same pattern data cycle Repeated transmission; the second method is to shunt the X data of each weft to m I / O interface boards first, and then serially shift the X / m data in the m I / O interface boards to the electromagnetic jacquard at the same time For each electromagnetic dri...
