Design and Implementation of Automated Test System Based on JSON

An automated test system based on JSON data exchange technology is proposed to solve the problems of low efficiency,long period and poor consistency on the aircraft assembly line of the ground manual test.The complex process flow is decomposed into a series of test actions that constitute test process according to certain logical or sequential order.The human-machine interface is developed by using LabVIEW,which can load the test process to complete the automated test and generate the test report.According to modular design,the test process and test procedures are segregated from each other to reduce system coupling and it has good expansibility,high flexibility and good maintainability.Application results show that this system can improve the test efficiency,shorten the test time,reduce the test error rate and be easy to maintain.
