Example Analysis of Drawing Frame Networking Technology
In order to realize the informatization of cotton spinning equipment,the characteristics of RS-485 bus communication interface are introduced.Taking the networking of 72 sets of JWF1310 drawing frames as an example,the topological structure of the RS-485 bus network with hand-in-hand connection is described in detail.Using PC as the master device and PLC as the slave device,grouping 18 sets of drawing frames into one group and using four repeaters combined with self-developed e system,the scheme design of data acquisition to the server is re-alized,and its specific implementation points are summarized.It is pointed out that through RS-485 bus+repeater mode,combined with the software and hardware design of e system,the data acquisition and analytical processing of 72 sets of drawing frames can be realized.The problem of data transmission distortion can be solved by adjusting baud rate,terminal resistance and grounding mode.Practice has proved the data transmission of the drawing frame networking scheme is accurate and the work is stable and reliable.
