Abstract

The invention provides an aviation ammunition universal test device intelligent interface adapter, and belongs to the field of aviation ammunition universal test systems. The aviation ammunition universal test device intelligent interface adapter aims to solve the problem that an existing interface adapter cannot process a test signal. According to the aviation ammunition universal test device intelligent interface adapter, a functional circuit, an FPGA, a CPU, and a 1553 communication interface circuit are added to the adapter to assist an aviation ammunition universal test device in finishing the ammunition test. The adapter completes corresponding test procedures according to instructions of the test device and returns the test result to the aviation ammunition universal test device. According to the aviation ammunition universal test device intelligent interface adapter, signal conditioning and distribution between the test device and aviation ammunition can be achieved, partial test procedures with strict timing requirements can also be achieved alone and the result is uploaded to the test device, so that burden of the test device is reduced by 60%, and universality of the test device is improved by 70%. The aviation ammunition universal test device intelligent interface adapter is suitable for the test tasks of multiple models of universal aviation ammunitionaerial bombs.

Description

technical field [0001] The invention belongs to the field of general testing systems for aviation ammunition, in particular to an intelligent interface adapter for testing equipment. Background technique [0002] The interface adapter is the intermediate link between the automatic test equipment and the test object, mainly to complete the signal distribution and conditioning tasks of the test object. The test process of aviation ammunition has strict timing requirements and high real-time requirements. The usual interface adapter has no test processing capability and only transfers the test signal to the automatic test equipment. Therefore, the design of the existing automatic test equipment is complicated and cannot The test signal is processed, and the versatility is poor. Contents of the invention [0003] The invention aims to solve the problem that the existing interface adapter cannot process the test signal, and now provides an intelligent interface adapter for gen...
