Research Of Remote Monitor And Maintenance Technique For HuaZhong CNC System

To solve the problem of service after sale and technique support of equipments in global market environment, remote operation, remote monitor and fault diagnostic methods of CNC machine are studied based on the CNC machine of WuHan HuaZhong Numerical Control Association in this dissertation. In the following parts, the details are introduced.Firstly, the architecture of hardware and software and the present state of network application of HuaZhong CNC system are introduced and studied. The whole structure of remote monitor and maintenance system are proposed in view of the requirements of functions of HuaZhong CNC-oriented machines. In addition, the system is divided into two modules of field server and remote monitor according as functions.Secondly, the design and implementation methods of field server module are proposed according to the requirements of the functions of module. The following contents are included: the integrated design of field server, data stream formats, transmission procedures and the way of implementation in communication between CNC machine and field server, remote client and CNC machine.Thirdly, the design and implementation methods of remote monitor module are put forward according to the requirements of functions of module. The following contents are included: the overall design of remote monitor module, the design of reconfigurable remote monitor interface and the safety control hierarchical of remote monitor.Finally, the working conditions about field server and remote monitor modules the author developed are introduced using some running graphs of the HuaZhong CNC network technique support and maintenance system finished by the group in which author attended. The main contents include remote reception of real-time and history information, remote operation of CNC machine, remote performance of test G-code and the fault alarm by e-mail and short message of mobile-phone of CNC machine etc.
