Development of Standardized Circuit Solutions for Control and Data Acquisition Systems of a Research Complex on the Basis of Electron-Beam Technological Installations

摘要

The structure, contents, and operations of electrical equipment, which are parts of a test bench for investigating the characteristics of technological electron guns, are reviewed. A list is given of critical problems that were solved with the equipment under which the basic requirements for system control and data acquisition were designed. Based on the classification of the control and recorded signals, the characteristics of input-output modules of digital and analog signals are defined. Taking into account the features of the equipment, standardized circuit solutions were developed that provide acceptable accuracy for control and signaling, as well as trouble-free operation of a computerized data acquisition system. The use of modem solutions providing galvanic insulation by optical transmission channel technology for both digital and analog signals is discussed. A method of selection of specialized microchips on the parameters of control and measurement signals is shown. Recommendations on the use of measuring complex for research and design of control systems of electron-beam welding installations are provided.
