Abstract

The invention provides a matrix switch device and system. The device comprises a control board, a matrix switch and a test connector. The matrix switch is electrically connected to the control board.Each pin of the matrix switch comprises a detection point pin and a test point pin. The detection point pin is connected to an input port of a detection circuit, and the test point pin is connected tothe test connector and is used for connecting an output port of a tested module UUT through the test connector. The control board switches the matrix switch such that a test signal inputted into thetest point pin is switched to the detection point pin. According to the mode of the invention, through the switching control of the matrix switch, the signal of the test point pin is arbitrarily switched to the detection point pin to carry out test of various functions, therefore, the mode can be applied to different functional tests of different products, and the wire connection mode is simplified by the connection of the connector. Therefore, the technical solution of the embodiment of the invention has the advantages that the versatility and flexibility of the test are improved, the development cycle is shortened, and the maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric tool testing, in particular to a matrix switch device and system. Background technique [0002] As a tool powered by an electric motor, an electric tool is a hand-held or movable mechanized tool that drives the working head through a transmission mechanism. It has the characteristics of easy portability, simple operation, safety and reliability. Electric tools are widely used in various fields, and the safety of the switches of electric tools is particularly important during use, so the switches of electric tools are usually tested for various indicators, such as voltage, current, displacement, and minimum steps of drive control. index. [0003] Among them, the switch network is an important part of the automatic test platform, responsible for the task of controlling the signal flow, and is the key to realize the interface design of the automatic test. The general test method is to switch on an...
