Multifunctional integrated test system

Abstract

The invention provides a multifunctional comprehensive test system. The test system is characterized in that in the test system, a computer is used as a control and data processing center; by controlling various multifunctional data collection cards, analogue signals and discrete signals are sent to and received from a tested member; an interface conversion circuit puts the same type of signal circuits in one group; AC and DC signals inputted by the interface conversion circuit are conditioned by a signal conditioning board, and the conditioned signals are sent to an analog-digital conversion board; and digital quantity is sent to the computer. The test system has the advantages of conveniently and visually entering test pictures corresponding to members in various models, improving measuring precision and flexibility, along with convenient measurement due to a self detection function and a measuring detection port of the test system.

Description

technical field [0001] The invention relates to a test system, in particular to a multifunctional comprehensive test system. Background technique [0002] Airborne fire control electronic equipment often needs to be tested in the field. The test equipment used in the past was developed in the early 1990s. The signal measurement uses pointer instruments and early digital displays. The measurement error is large, and the data display Unstable; signal conversion uses a large number of switch conversion lines. Due to frequent use, poor contact of switches often occurs; for the measurement of various AC signal parameters, it is necessary to connect external corresponding measuring instruments. The wiring is complicated and the operation is cumbersome. Airborne components are equipped with special testers, and there are many test equipments, which are scattered and inconvenient for management and maintenance.
