[Abstract]:With the development of science and technology and industry, ultraviolet radiation measurement technology is widely used. The verification of ultraviolet illuminance meter is also very important. At present, the local metrology departments are still using manual verification device to verify the ultraviolet illuminance meter, with low efficiency and poor accuracy. This paper studies the automatic control system of the verification device of ultraviolet illuminance meter according to the verification regulation and the verification characteristics of the ultraviolet illuminance meter. The contents are as follows: first of all, In this paper, according to the present situation of the verification of ultraviolet irradiance meter, the problems existing in the verification work are studied and analyzed. According to the present situation of the study on the verification of ultraviolet irradiance meter and the application technology to realize the automatic verification of the ultraviolet irradiance meter, The significance of the research is determined, and on the basis of this, the system design requirements and the main contents of the research are determined. Secondly, According to the system design requirements, the overall control scheme of the system is formulated. The overall control scheme of the system determines the design structure of the system. The composition of the system and the functions of each part are explained. According to the overall scheme of the system design, the main control technologies of the system application are analyzed. Thirdly, according to the overall scheme of the system design and related working principles, The system design process includes the hardware design and software design of the motion control system controlled by single chip computer and the design of the upper computer. Through the software and hardware design of the system, a simple system experimental platform is built. Some functions of the system are tested through the experimental platform, and the performance of the system is evaluated by the test data. The system has a reasonable allocation of resources, and the system is able to coordinate its work, The function of the system can be realized. The automatic control system designed in this paper uses the upper computer as the man-machine interface to send the control command and display the displacement data of the moving platform. The single chip microcomputer is used as the control core to control the motion platform by receiving the control instructions from the upper computer to verify the related motion. The rotary encoder and the limit switch are used as the main detecting devices to realize the closed-loop control of the movement platform displacement. The system realizes the semi-automatic verification of the ultraviolet irradiometer. The successful design of the system provides a new method for the verification of ultraviolet illuminance in various measurement departments, which will greatly improve the efficiency of the verification of ultraviolet illuminance.
