Abstract:With the development of automatic control, the requirements for diversified support of automatic calibration software tasks, easy expansion of functions, and mutual use of system resources in the automatic calibration process are becoming higher and higher. In this paper, the operation mode, data interface format, and secondary development strategy of calibration and verification software are studied, and the information management subsystem, calibration and verification subsystem, and secondary development subsystem are designed according to software development standards, The universal automatic calibration and verification platform covering the whole process of measurement calibration is realized, which meets the requirements of flexible expansion of calibration and verification projects and sharing of resources.
