Middleware Design In Automatic Test System And Its Application In An Ats

Nowadays,the rapid development of network technology and computer technology has promoted the development of automatic test technology in a new direction.Because the traditional automatic test system is hindered by factors such as test environment and space,the developed automatic test system may not meet the high complexity test requirements.Automatic test systems need to be developed in the direction of networking and information.This topic combines the research status of today's automatic test technology,combined with the existing automatic test system of the teaching and research room,in-depth study of middleware technology,developed a middleware that can be cross-platform automatic test,and realized the distribution during the operation of the automatic test system.Test function and data management functions.In this system,the middleware as a software or service provides a corresponding operation interface for the development of the upper test application software,and shields the operation of the underlying hardware instrument.This paper mainly discusses the remote process call module and data management module of the automatic test system based on middleware.The middleware realizes the distributed test function and data management function in the process of automatic test system operation.The specific implementation content is as follows:1.Based on the software framework and hardware of the existing automatic test system,combined with middleware technology and related software development technology,designed an automatic test system framework based on middleware,realized distributed test system,and realized automatic test system customer.Cross-platform of the terminal program.2.Complete the design and implementation of the remote call module of the automatic test system middleware.The open source gRPC framework is combined with the instrument module of the existing automatic test system to realize the instrument control module based on remote procedure call.3.Complete the design and implementation of the data management module of the automatic test system middleware.The upper layer software of the automatic test system can access the database through the middleware data management module,and save and query the data generated during the test process.4.Apply the middleware to an ATS to complete the self-test function,mainly complete the self-test of the module in the system,display in the test self-test software interface,the application of this module as the middleware,the proof of the normal operation of the self-test software The design of the middleware achieved the expected results.
