Background technology
Parallel kinematic mechanism machine comes down to the product that parallel robot technology combines with machine tool technology, develop parallel kinematic mechanism machine from the U.S. in 1994 since, this new device has become one of focus of international research, is described as " the lathe of 21 century.Parallel institution is compared with serial mechanism; Have rigidity height, response speed and reach the kinematic accuracy advantages of higher soon, therefore receive the concern of academia and industrial community, though parallel institution has above-mentioned tempting advantage; But it has the little shortcoming of range of movement again simultaneously; Particularly drawback movement is limited in scope, and these shortcomings advantage of serial mechanism lathe just, so the CNC Series-Parallel Machine Tool that parallel connection, series connection are adopted simultaneously has more practical value.String and hybrid mechanism technology are relatively ripe now, but string and series-parallel connection control system are because the complexity in its control has seriously restricted the hybrid mechanism application.There are a lot of colleges and universities and research institution to carry out the research of combined hybrid system at present; But all concentrate on series-parallel connection control algolithm itself; Or series-parallel connection Design of NC system; The series-parallel connection Control System Design is a complicated system engineering, and it relates to the knowledge and technology that software is learned, controlled each side such as and system analysis engineering.Complete exploitation series-parallel connection control system causes the construction cycle long, whole complication system stability checking difficulty.Series connection control system that can not multiplexing existing maturation.
Summary of the invention
The utility model is to the proposition of above problem; And develop a kind of on the path of traditional series connection digital control system control loop intercepting control signal; This control signal is a cascade system Cartesian coordinates signal, through string and series-parallel connection algoritic module this signal is handled, and is mapped as the coordinate signal (real coordinate) on the physical axis to the series connection signal under the cartesian coordinate system (empty coordinate); Accomplish the actual situation coordinate transform, realize that the control of series-parallel machine tool realizes combined hybrid system.
A kind of based on the digital control system that realizes series-parallel connection control on the series connection digital control system, comprise
Receive user input data, and system information is shown the man-machine interaction unit that supplies the user to watch and use;
Connect man-machine interaction unit, and the data of man-machine interaction unit input are carried out interpolation, obtain the interpolation data of each respective shaft, after an interpolation of every completion, generate the interpolation module of an interpolation end mark simultaneously;
Connect interpolation module, and the interpolation data buffer cell stored of the interpolation data that interpolation module is sended over and end mark;
Connect the interpolation data buffer cell, and interpolation data and the end mark that the interpolation data buffer cell sends over sent to the motion output unit on the motor; It is characterized in that also comprising,
Connect the interpolation data buffer cell, be used for detecting the cycle detection unit of the interpolation end mark that the interpolation data buffer cell stores;
Connect cycle detection unit and interpolation data buffer cell, receive the interpolation data storage unit of the interpolation cycle data in the interpolation data buffer cell being stored after the notice of sending the cycle detection unit;
Whether connect interpolation data storage unit and interpolation data buffer cell, be the parallelly connected axis data judging unit that parallelly connected axis data is judged to each interpolation data in the interpolation data storage unit;
