Problems solved by technology

This will lead to the need to redesign the circuit and build the circuit if the test requirements are different for the same external resource component
And because different products or DUTs have different circuits, it is often necessary to prepare a large number of spare parts for replacement in case of damage.

Abstract

The invention provides an expansion board, a detection system and a detection method. The expansion board comprises at least one input interface, at least two physical expansion circuits, output interfaces and a resource selector, wherein structures of the physical expansion circuits are different; the output interfaces are in one to one correspondence with the physical expansion circuits; the resource selector is connected with the input interface and the physical expansion circuits, receives a control command transmitted by a control part, and connects a target physical expansion circuit, corresponding to a target output interface, among the physical expansion circuits with a target input interface according to information of the target input and output interfaces in the control command, so that an external resource part of the target input interface is connected to detect a detected piece connected to the target output interface. According to the invention, the same external resource part is prevented from the inconvenience of repeated circuit design caused by different detection requirements.

Description

technical field [0001] The invention relates to the detection field, in particular to an expansion board, a detection system and a detection method. Background technique [0002] In the prior art, various detections, such as current detection and voltage detection, are often required during research and development or production. At this time, various external resource components need to be used. [0003] Due to the different test requirements of various products, some external resource components need to design circuits according to the needs of the DUT to expand the test function of the current external resource components, and then meet the test requirements of the product. In this way, for the same external resource component, if the test requirements are different, the circuit needs to be redesigned and built. And because different products or DUTs have different circuits, it is often necessary to prepare a large number of spare parts for replacement in case of damage...
