Cnac Xx Hospital Remote Calibration System

Nowadays, science and technology develop rapidly, all kinds of areas put forward new demands of their own development. In the fields of metrology and calibration, traditional calibration methods have some disadvantages, such as long traceable chain, big calibration cycle, manage difficult, high cost and low efficiency, and these disadvantages tend to evident, so it is no longer suitable for the rapid development of metrology and Calibration requirements.A number of international units of metrology and calibration laboratory have researched a new calibration method—Tele-Calibration or e-Calibration, some technology mature research projects even have been used into the practical application. In our country, studies of Tele-Calibration are relatively few, so combine with the objective actual situation of our country's metrology and calibration, researching Tele-Calibration technique is necessary and of practical significance.This topic roots in the topic of Metrological Center of China XX Aviation Academy. On the base of studying the actual demands of calibration, this paper has researched Tele-calibration technology based on LabVIEW. This paper not only analyzes the disadvantages of traditional calibration and the advantages of Tele-Calibration, but also builds the structure of Tele-Calibration system. This paper focuses on the methods of calibration program's remote control, and uses the method of "DataSocket +Remote Panels" to implement the function of calibration laboratory controlling the calibration program of calibration scene and real-time transmission of data. Focuses on the methods of LabVIEW applications accessing database, this paper put forward the method using ".net" constructor in LabVIEW to call DLL in order to accessing database. Then, this paper designs a set of Tele-Calibration system and describes the process of actualizing Tele-Calibration in detail. At last, this paper analyzes the security of Tele-Calibration system.The experimental results show that Tele-calibration technology which this paper has researched realizes the function of Tele-calibration with the advantages of operating simple and low-cost. It can be able to meet the requirements of real-time transmission of data in Tele-Calibration process and implement alternating operation between calibration laboratory and calibration scene.
