Universal automatic testing and fault diagnosis system

Abstract

The invention relates to a universal automatic testing and fault diagnosis system which is characterized in that a universal automatic testing platform, input-output equipment and an interface adaptor are included, the input-output equipment is connected with the universal automatic testing platform, tested communication equipment is connected the universal automatic testing platform through a corresponding equipment testing adaptor, the universal automatic testing platform comprises a zero-slot controller and testing instruments, the zero-slot controller is provided with a testing system and a fault diagnosis expert system, the testing system is used for carrying out initial setting on the universal automatic testing platform and the interface adaptor during automatic testing and sending testing orders and testing parameters to the testing instruments according to testing needs, the testing instruments transmit corresponding testing signals to the tested communication equipment for testing through the interface adaptor according to the testing orders and the testing parameters, testing result signals of the tested communication equipment are fed back to the testing instruments through the interface adaptor, the testing system collects the signals of the testing instruments and carries out processing and analyzing, if testing results are not qualified, the fault diagnosis expert system carries out intelligent fault diagnosis, and fault is located to the plate level.

Description

technical field [0001] The invention relates to the technical field of automatic testing and fault diagnosis, in particular to a general automatic testing and fault diagnosis system suitable for twelve types of communication equipment. Background technique [0002] There are many types of communication electronic equipment, complex signal types (according to different classification methods can be divided into analog / digital signals, wireless / wired signals, low-frequency / high-frequency signals, voice / image / data signals, etc.), many technical parameters, and accurate testing Accuracy and real-time requirements are relatively high. [0003] Currently widely used communication equipment test and diagnosis systems are usually based on the detection of typical parameters of products, most of which are a set of test equipment for a type of communication equipment. In addition, for the signal test and processing results, most of the fault diagnosis is carried out by manual judgmen...

Problems solved by technology

In addition, for the signal test and processing results, most of the fault diagnosis is carried out by manual judgment. The efficiency of this manual diagnosis method is relatively low. rich, the diagnosis result may be more accurate, on the contrary, the diagnosis result may be far from the actual fault, which guides the maintenance personnel in the wrong direction and cannot achieve effective maintenance guarantee
