Study On Dynamic Signal Analysis System With Poly-morphism Function

In the epoch of information, it becomes the more and more important resource in the life and technology domain gradually. Dynamic signal test technology is the very integrated one in order to acquisition and process various dynamic signal. The application domain of the dynamic signal analysis is very broadcast. For example in the domain of aviation, cosmonautics, military, communications and transport, environment, mechanical, medical, daily mechantronic production and the resource of robot.These years, dynamic signal analysis instrument with multiple channel and high performance is widely applied. For the diversification of the test need, the complexity of the design increases gradually. In order to settle the contradictory between the designer and the customer, the design clou, that is"the consumer of the measurement system is also the designer of it"is proposed. In addition, the conception of poly-morphism function is proposed. In the paper, we establish the software architecture of parameter shared model in order to accomplish the design of the dynamic signal analyzing measurement system with poly-morphism function according to the design clou.During the process of the research, three parts of the job is done as following.①In order to decrease on the complexity of test design, as well as increase on the flexibility of the system function, the design clou of the system, that is"the consumer of the measurement system is also the designer of it"is proposed. So that, the partical job of the design, which astrict the flexibility is attorn to the customer. Customer may recombine the data analysis process dynamicly.②According to the design clou, that is"the consumer of the measurement system is also the designer of it", and the conception of the poly-morphism in the technology of Object-Oriented Technology, the conception of poly-morphism is proposed in the paper. Meanwhile, the software architecture of parameter shared model is researched and is applied in the establishing of the system frame successfully. Then the poly-morphism function is implemented. Aim at the analysis function, the interface of the instrument with the style of function flow is designed. Fact means that the interface of the instrument is friendly and is convenient to application.③According to the design target of the system, it achieves the analysis function of four common used instruments which are the oscillograph, frequency spectrum analysis instrument, coherent and transfer function analysis instrument, and noise analysis instrument. In allusion to achieve the analysis function, analytic model and algorithm model are researched in paper, and the application of which is also generalized.According to the theory, we develop the instrument for dynamic signal analysis with poly-morphism function. The correction of the software architecture of parameter shared model is approved in the accomplishing of poly-morphism function. So that, the design clou, that is"the consumer of the measurement system is also the designer of it"is accomplished.
