[Abstract]:CNC machine tool is a precise electromechanical control equipment with high machining efficiency and high intelligence. Because of the complexity of its own system, the maintenance after the failure is mostly time-consuming and labor-consuming, which seriously delays the production plan. The purpose of the remote monitoring and fault diagnosis of NC machine tool is to monitor and diagnose the condition of the machine tool in the process of machining. Timely detection of machine tool anomalies and failures, to avoid causing greater losses. The data acquisition of NC machine tools is the basis of monitoring and diagnosis. Accurate, effective and timely data is an effective guarantee for monitoring and fault diagnosis of NC machine tools. This subject takes the remote monitoring and fault diagnosis system of NC machine tool as the overall goal. It is implemented in three stages: data acquisition of NC machine tool, network platform construction and fault diagnosis algorithm research. In this paper, the data acquisition of CNC machine tools and the development of related software have done the following work: 1. The research of data acquisition methods of CNC system: the hardware structure and software system of CNC system are studied. In view of the subject application object, Siemens open 840D numerical control system, The data acquisition method based on OPC specification is used to collect the internal data of numerical control system. The data processing method of mass process data is studied. On the basis of studying the related methods of mass process data processing, a data compression processing algorithm based on rotary gate algorithm is proposed. The algorithm is implemented and tested to verify the superiority of the algorithm. The realization of data acquisition software for NC machine tools is realized. According to the OPC specification and the actual situation of Siemens 840D, the coding of data acquisition client software is implemented by using C # language. Including the basic data acquisition function, data compression processing (combined with Matlab mixed programming) and communication with the database. The client software is embedded in HMI by HMI secondary development supported by Siemens. The test of data acquisition software for NC machine tools: whether the data acquisition software can be deployed in MMC and whether it will affect the number of data acquisition software? The problem of the normal operation of the control system, In this paper, the function and performance of the acquisition software are tested. The test results show that the client software embedded in MMC can accomplish the expected work and has little effect on the NC system.
