Data communication method of knitting machine needle selector, storage medium and knitting machine

Abstract

The invention discloses a data communication method of a knitting machine needle selector, a storage medium and a knitting machine. The method comprises the steps that action data is set to be N bits,and a data bus DATA is set to be N+1 bits; at the rising edge of the clock signal CLK, a sender latches the address code on a data bus DATA and outputs the address code; at the falling edge of the clock signal CLK, the sender latches the action data and the check code on a data bus DATA and outputs the action data and the check code; a receiver reads the address code from the data bus DATA at therising edge of the clock signal CLK and compares the address code with a preset address value of the receiver; and if the address is matched, the receiver reads action data and a check code from thedata bus DATA at the falling edge of the clock signal CLK, the check value is obtained through calculation according to the action data and the address value, the check value is compared with the check code, and if the check value is matched with the check code, it is judged that the action data is valid. Through the arrangement, the anti-interference capability of the needle selector capable of supporting the maximum path number and data communication is improved.

Description

technical field [0001] The invention relates to the field of textile production, in particular to a knitting machine. Background technique [0002] With the development of the market and the change of production demand, the knitting machine is developing towards the direction of multi-needle and multi-way needle selectors. At present, the existing knitting machine jacquard control system usually supports a maximum of 256 needle selector ways, but Manufacturers have put forward demands for more than 256 needle selectors. [0003] Such as figure 1 As shown, the current communication protocol output signal between the jacquard control system and the needle selector mainly adopts a clock signal plus an 8-bit data bus, and the transmission method is: latch the address code in the data at the rising edge of the clock signal CLK On the bus DATA, the action data of the needle selector is latched on the data bus DTA at the falling edge of the clock signal CLK. In this way, the acti...

Problems solved by technology

[0004] But this method has the following problems: (1) Due to the 8-bit data bus, only one data byte can be transmitted, and the maximum number of channels supporting the needle selector is 256 in theory; (2) The transmission anti-interference ability is poor, there is no Calibrate the data, the reliability cannot be guaranteed, once the signal is disturbed, it will cause the needle selector to malfunction and produce defective cloth, which will affect the product quality
