0. Preface
The majority of the existing weaving electrical control systems are based on asynchronous motor drives. In the situation where the demand for energy saving is increasing day by day, the energy saving of the permanent magnet synchronous servo motor drive system is getting more and more attention, and the permanent magnet synchronous servo motor is applied to the sword. Rod loom became a reality. In this context, the development of a permanent magnet synchronous servo motor for the drive spindle, winding and let-off servo motor driven servo motor control system has become necessary, but also will greatly promote the technical upgrading of textile equipment.

1.1 The composition of the mechanical system
The rapier weaving electrical control system includes a master control system, a spindle servo drive system, an electronic take-off warp system, an off-machine reel system (optional), a weft selection system, a multi-arm control system, and an indicator light system. As shown in Figure 1.

1.2 Full-servo rapier performance parameters and features
The full servo rapier weaving system provides the total solution for the electrical part of the loom. The main controller adopts 32-bit CPU, fast operation speed and high control precision; 10å‹ color touch screen, simple interface, intuitive interface, easy to learn and easy operation; coiling, let-off, and spindle drive adopt high-precision AC servo system to overcome the traditional The lack of mechanical transmission structure, easy installation, small maintenance workload, and certain energy-saving effects; spindle servo motor oil-cooled motor, more suitable for rapier loom working environment, to avoid the disadvantages of common air-cooled motor cooling effect is not good Due to the use of electronic reeling and let-off, it can effectively eliminate parking stalls, hidden stalls, boot waves, etc., due to fabric tension caused by changes in tension, and at the same time can be achieved without changing the gear weft density function; Because the entire system uses a high-speed main control system and a high-precision full-servo system, the RS2000-1728S2000 rapier weaving control system has high weft density adjustment accuracy, low maintenance, fast weaving speed, and high fabric quality. Features. At present, the entire system can run 550 rpm loom speeds when used with JWG1728 rapier looms, and our design speed can reach 800 rpm;
The machine features are as follows:
Sup2; production management function

n Up to 8 weft selection fingers can be controlled to perform weft selection. At the same time (in the same weft), only one weft finger can be controlled for weft selection.
n can set two multi-arm angle parameters; according to the set multi-arm angle, drive the multi-arm electromagnet in these two parameters, 1 represents the heald frame rise, 0 represents the heald frame drop;
n Two weft angle parameters can be set; according to the selected weft angle, weaving finger motion is driven within these two angle parameters;
n When picking the weft in positive and negative directions, the picking weft finger does not move, but the current picking weft finger number should be calculated according to the pattern;
n can be set for each machine cycle (corresponding to a weft) of the action of each piece of heddle and the weft index number, heddle motion parameters and the weft index number corresponding to a one-to-one; a certain number of continuous data constitute a pattern;
n can set 1100 weft yarns corresponding to the multi-arm motion parameters and weft index number parameters;
n can be set to 5 kinds of patterns, each pattern can be set to the total number of wefts, the current number of weft (dynamic), set the corresponding parameters for each pattern; 5 patterns of the total parameters can not exceed 1100;
n can set the current pattern;
n Flower type setting, setting method, can copy, delete, increase, decrease, all set, all clear and so on;
Sup2; Data saving requirements:
n In addition to the spindle servo and electronic coiling subsystem data, the data is stored in the electronic controller;
n Initialize subsystem data through CAN communication;
n The spindle servo and electronic coiling subsystem data are automatically shared with the electronically controlled data.
n Keep the synchronization with the subsystem when sharing modifications and saves;
Sup2; CAN communication:
n Through CAN and spindle servo, coiling warp, HMI panel communication.
n can achieve shared parameter synchronization.
Sup2; Fault protection requirements:
n cut off, stop;
n Weft break, weft stop;
n The oil pressure is too small;
n pressure difference is too small;
n Multi-arm failure;
n Take-over failure;
n spindle servo system failure;
2. Control system
The control system selected the curly warp delivery drive independently developed by Shanghai Inventronics Technology Co., Ltd., the ARM-based program controller, and the weft detection mechanism. Since all of them are independently developed by Shanghai Inventronics, all equipment can be realized. Seamless links, perfect compatibility. The overall architecture is shown in Figure 2.

3. Conclusion
The full-servo rapier weaving machine is one of the more advanced equipments in the textile machine industry. It has made revolutionary progress in the automation of textile machinery, improving the technological level of enterprises, stabilizing product quality, increasing production efficiency, and achieving civilized production. Has a major role. Over the years, with the rapid development of the domestic textile industry, full-servo rapiers that use servo-drive motors instead of asynchronous motors will surely find wide application. Thanks to the high performance of Shanghai Yueneng Power Products, this all-servo rapier loom based on Shanghai Yueneng Power Electronic Control System has reached the leading level in domestic textile machinery and equipment, which is a very competitive product design.
