As a new type of composite material pipe, Fiberglass Reinforced Plastic Pipe has an extensive application prospect, with its advantages such as light weight, high strength, corrosion resistance, smooth inner wall, flow rate, not scaling, leaving no residue, non-blasting, high reliability, long life to be used and its lower cost. In nowadays, it has been widely used in agriculture, electricity water, urban water supply drainage fields and so on.Fiberglass Reinforced Plastic Pipe Production Line Control System is an important equipment for the production of glass fiber reinfoced plastic pipe RPM, however, most of the winding machine control systems sold in market today are adopted the way that embed NC to PC, in this mode the motion controller integrates with computer. Such machine restricts the completely opening-up characteristic of the system, and also in the actual processing of the production process, because the computer system is vulnerable to outside interference, and it is not stable enough to make the entire winding machine system stability, then the reliability of the whole winding machine system will be declined. In order to solve this above problem, an embedded coarse pipe winding machine which adopts the TRIO MC302 as the core, the touch screen DOP-B07S200 as the support, and also the AC servo system serves as the driven components is designed.This system is an overloaded system, in the production process, as the winding process requirements, motor needs to commutate constantly, and needs to pick up yarn in the winding yarn break occurred during the time, both occasions need to run low-speed motor. When the system is running lowly, the low-speed crawling phenomenon for the electric machine will exist. This will not only affect the system's dynamic operational characteristics, but also will acceler- ate the speed of wearing and tearing of mechanical components, so this paper firstly carries out simulation studies of the friction motor power studies to guide the follow-up to the next bit plane in the PID parameters. Simulation results show that the motor speed curve will appear"volatility"phenomenon and displa-cement curve will appear"wavy line"phenomenon when the motor speed of a low to a certain extent. In order to suppress the occurrence of this phenomenon, using fuzzy PID control method to control the motor, the results show that the fuzzy PID control method can effectively reduce the probability of this phenom-enon, and improve the system dynamic performance. Then the overrall program of this numerical control system is designed and at the same time, the hardware, electrical design, including the electrical design of servo systems, controller's I / O port electrical design are also carried out, with the integration of the morden open design concepts and design process requirements. In the aspect of soft wear design, this system adopts Windows as a development platform and the Screen Editor 2.00.05 programming software as the development tools to complete the soft wear development of this numerical control system, with a set of parameters, I / O port testing, real-time display and other functions. According to the actual processing requirement, this system makes used of TRIO to develop a next-bit machine motion control procedures in order to complete the specific machining operation, the program can be realized in three kinds of operating modes: manual, semi-automatic and automatic. After the test in practice, RPM Pipe Winding Machine CNC System designed in this paper, running in good condition, and reached the pre-design requirements.
