With the advancement of science and technology, measuring instrument technology is gradually developing towards virtual instrument technology. Simple, universal and expandable development has become an important indicator for virtual instrument development. In order to solve the problem that the virtual instrument development software on the market is not easy to expand and the operation efficiency is low, a method for realizing universal virtual instrument front panel running platform is proposed. The main principle is that the platform instrument component exists in the form of jar package, which is convenient for expansion and platform loading. Different instrument scripts can generate different virtual instruments, and a one-to-many observer-based data exchange mechanism is proposed to facilitate communication between components and facilitate communication between platform and hardware system. An example of a signal generation display demonstrates the feasibility of the universal operating platform.
