Aiming at the shortcoming of general ratio controller for Continuously Variable Transmission(CVT),an improved PID control algorithm was presented,which was more suitable for mass production requirements and more adaptive.

To accomplish the demand of continuously variable transmission(CVT) fault diagnosis,the structure of CVT fault diagnosis system is built and the application model of Back-Propagation Neural Network is established aiming at the features of CVT faults.

The reason to shift the gears in the transmission during the auxiliary braking was presented and it was explained that here the fittest gearbox is continuously variable transmission(CVT).

All the parts of high speed braiding machine and their fuction were presented,the implement of man-machine interaction composed of LCD and keyboard was given,the distance stepless speed regulation by transducer and the intelligent handling of other actuators were expounded moreover,the RS-485 LAN makes the unified management of many high speed braiding machine by only one upper PC more convinient.
