Development of Highly Reliable Integrated GATS for a Certain Helicopter

The repair factory has developed a universal automatic test system (GATS) for the electronics in a certain type of helicopter, which can automatically detect and quickly isolate the failures of electronics of various systems, speed up the repair of failures, and ensure the completion rate of equipment. Based on the comprehensive analysis of the causes, types and effects of failures, as well as the test requirements, test signals and performance characteristics of the electronics, the hardware platform of GATS was designed and developed by the advanced automatic test technology, bus technology, virtual instrument technology, signal-oriented software architecture and programming language etc. in China and abroad. VXI, GPIB, 1553B and LAN bus instruments were adopted to reduce the volume of GATS on the premise of meeting the test requirements. Virtual instrument technology was used to achieve the independence between the test program and hardware resources. The signal-oriented ATLAS language was applied to write the test programs, which made the test programs easy to be transferred. Thus, the development efficiency of test programs was improved. Long-term application verifies that the GATS can complete the function inspection, performance detection and service failure isolation of various electronics of the helicopter. It is universal, reliable, durable and easy to operate and has certain maneuverability and is suitable for equipment support in ground environment.
