Background technology
Along with deepening continuously of Weaving device automated process, adopt computer and servo drive system to realize that the technical application of warp knitting machine guide bar shogging system is general day by day.Warp knitting machine electronics horizontal movement control system has centralized control and distributing to control two kinds at present; The thinking of these two kinds control systems all is the position signalling of dynamic acquisition master uranium; Change to drive each guide bar shogging executing agency according to the synchronism of this signal, make it accomplish the displacement action of technological requirement according to pattern data.The existing guide bar shogging control system that uses is divided into two-stage on basic framework: with the one-level control module is core; Receive the pattern data that host computer transmits; Dynamic acquisition main spindle's signal also carries out judgment processing; And at the appointed time displacement command is sent to the secondary control module, make it drive servo drive unit and carry out corresponding actions.Can realize basic function though do like this; But because functions such as transfer of data, collection in real time, logic judgement, dynamic response are concentrated on the one-level control module; Be tending towards in the servo drive unit response under the situation of the limit, the whole system real-time all receives the restriction of the response performance and the signal transmission time of one-level control module.Since the hysteresis of response and signals transmission, and can't make sley bar in the effective time of machine high-speed cruising, accomplish the compulsory exercise of flower type, so limited the raising of warp knitting machine spindle speed; In addition, because the problem of communication bandwidth and signal attenuation is difficult in a plurality of secondary control modules of connection under the one-level control module, so limited the quantity of traversing sley bar in practical application.
The utility model content
Cause the deficiency that spindle speed is slow and limited the quantity of traversing sley bar in order to overcome existing warp knitting machine sigal transfering lag, the utility model provides a kind of dedicated control system of high speed warp knitting machine guide bar shogging.
The utility model solves the technical scheme that its technical problem adopted: a kind of dedicated control system of high speed warp knitting machine guide bar shogging; Comprise central processing unit, embedded control chip unit, local area control unit one, local area control unit two, local area control unit three and high-speed serial communication line; Be provided with the embedded control chip unit in the central processing unit; Local area control unit one is connected in series with central processing unit, local area control unit one, local area control unit two with the local control module threeway cross the high speed null modem cable and be connected.
According to another embodiment of the utility model, comprise that further main spindle's absolute encoder and central processing unit are connected in series.
According to another embodiment of the utility model, comprise that further local area control unit three and servo drive unit are connected in series.
The beneficial effect of the utility model is that the dedicated control system of this high speed warp knitting machine guide bar shogging is simple for structure efficient, divides the work clear and definite; Stable performance; Dynamically set up the closed loop online feedback with transmission of open system Bus Real Time and high-speed serial communication, guaranteed real-time, accuracy and the stationarity of machine guide bar shogging in the high-speed cruising process, and system has good autgmentability; Broken through mechanical floral disc installation dimension restriction technology and spent high constraint, be easy to use and promote.
