Comprehensive CNI system testing device

Abstract

The invention discloses a comprehensive CNI system testing device. A comprehensive CNI system testing host comprises a radio frequency function module combination, a height simulator, a main control computer and a signal interface, and a radio frequency feeder line used for detecting a tested object is connected with the comprehensive CNI system testing host. A tested object is connected with a test accessory used for preventing the tested object from being damaged by no-load state emission signals, and the comprehensive CNI system test interface adapter is respectively connected with the comprehensive CNI system test host and the tested object. Meanwhile, a comprehensive management program is loaded in the comprehensive CNI system test host, and the comprehensive management program is developed by adopting a signal-oriented universal automatic test program; according to the method, the test problem of a traditional comprehensive CNI system is effectively solved, the method has the secondary development capability and the proper expansion capability of a user for the test program, and the user can simply upgrade the test program on the basis of an existing automatic test program soas to meet the test requirement of product change.

Description

technical field [0001] The invention relates to the technical field of testing instruments, in particular to a comprehensive CNI system testing device. Background technique [0002] CNI is the abbreviation of communication navigation identification system, which is an important part of the avionics system. With the rapid development of electronic technology, its technology is developing in the direction of integration, modularization and digitalization. There is a considerable difference between the integrated CNI system and the traditional CNI system. The difference is being transformed from the device level to the module level. With the rapid development of aviation radio technology, the technical complexity is increasing, the types of airborne equipment are diverse, the demand for testing is increasing, and product replacement is fast. It often takes a long time from the start of a generation of product testing to the corresponding test guarantee testing equipment is in ...

Problems solved by technology

With the rapid development of aviation radio technology, the technical complexity is increasing, the types of airborne equipment are diverse, the demand for testing is increasing, and product replacement is fast. It often takes a long time from the start of a generation of product testing to the corresponding test guarantee that the test equipment is in place. Often the equipment is in place, but the peak period of test demand has passed, and the equipment cannot be fully utilized.

At the same time, the traditional test equipment cannot meet the comprehensive CNI system test. The comprehensive CNI system test equipment solution provided by the finished product factory uses multiple traditional test instruments, special test interfaces and software architecture, which is extremely expensive and highly specific. Due to the lack of procurement costs, Equipment matching can not keep up
