Cnc Windows Ce-based Handheld Terminal Design

Numerical control machine tool and the manufacturing system constituted by which is important foundation of reforming traditional industry and setting up digital enterprise. Now there is a trend of miniaturization in the programming and control of the NC equipment. According to this, we put forward to develop embedded NC handheld terminal used for NC equipment in the workshop. It will change the operation mode of NC machine tool to use this handheld terminal, turn the priority from the machine to the people. Operators are no longer constrained by the machine tool in whatever position or posture. Operator can operate more machine tools in the more convenient and more comfortable way. Moreover, it is possible to evolve this terminal to NC personal numerical assistant (PDA), thus the NC machine tool will work in a higher level.This thesis mainly completes the following works in designing embedded handheld terminal applied to NC machine tool. First, we analyze the handheld terminal's development and application in the domestic and abroad. The design, realization and relevant technique of the embedded NC handheld terminal are summarized. Based on above, we put forward a whole solution of the embedded NC handheld terminal based on Windows CE.net. According to actual demand and expansionary, the terminal's hardware platform is determined. We design a good software structure. Based on the software structure, it can be very convenient to expand other functions. In the stage of constructing the terminal's OS platform, we develop the drivers for the some peripheral equipments, define the BSP and export the SDK used the next development. In the stage of application development, we primarily develop some NC system software module. In the NC code edition module, the system main interface , document edition and soft keyboard used to input are realized. Then, the NC code is processed by the lexical analysis, syntax analysis and error is displayed on screen in the NC code diagnostic module. In the communication module, it is realized that the handheld terminal...
