Adapter with self-checking circuit and system interface integrated structure

Abstract

The invention relates to the technical field of self-checking and testing systems of adapters, in particular to an adapter with a self-checking circuit and system interface integrated structure. The adapter comprises a self-checking circuit module and a system interface adaption module; the self-checking circuit module comprises a DSP (digital signal processor) main-control module, a 1553B module, an RS422 module, an I / O (input / output) module and a power supply module; the system interface adaption module comprises a signal conditioning module, an isolation module and an impedance matching module which are arranged on a motherboard. Since the self-checking circuit module and the system interface adaption module are integrated and then connected with a testing platform, the problem about separation of a detection function and a self-checking function of automatic testing equipment is solved, and the equipment can complete self-checking of analog quantity and discrete quantity and 1553B process self-verification.

Description

technical field [0001] The invention relates to the technical field of adapter self-inspection and testing systems, in particular to an adapter with an integrated structure of a self-inspection circuit and a system interface. Background technique [0002] As system self-inspection technology is more and more used in the production, maintenance and guarantee of equipment, people's requirements for modularization, portability and test accuracy of system self-inspection technology are also increasing. In the past, in order to verify the correctness of the system interface and channel, the traditional general automatic test system needs to be connected to the general test platform through an independent self-test simulator. The self-test simulator simulates the excitation signal, and the test platform performs signal conditioning through the interface adapter. Transfer to measure. The traditional self-inspection test simulator is generally in the form of an industrial computer,...

AI Technical Summary

Problems solved by technology

The traditional self-inspection trial self-inspection simulator is generally in the form of an industrial computer, so that the number of cable connections during the self-inspection test is large, the self-inspection preparation time is long, and the system interface adaptation cannot be injected into the BIT design. Therefore, the rapid self-inspection of the system cannot be achieved.
