Abstract
In test and measurement systems, real-time monitoring is the effective method for obtaining the running condi- tions and making fault diagnosis in testing system. In this paper, a universal real-time monitoring system based on User Datagram Protocol (UDP) is discussed. Firstly, the component structure of monitoring system is introduced, and compari- sons of various kinds of data transmission modes between the front-end acquisition module and the back-end monitoring module are made. Secondly, the characteristics and data communication mode of UDP are discussed, and the general pro- cess of real-time data analysis and curve plotting are studied. Meanwhile, a multi-channel data acquisition and monitoring system application instance for aerospace testing is designed and analyzed. It is demonstrated that the proposed design method can satisfy the test requirements, and because of the universality, which can be applied to other test fields by means of appropriate transformation or revise.
